Astro Pi is 10: A decade of your code in space 

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/astro-pi-is-10-a-decade-of-your-code-in-space/

Today, we are marking the 10th anniversary of the European Astro Pi Challenge.

At 11:03 on 15 December 2015, former ESA Astronaut Tim Peake launched from Baikonur cosmodrome in Kazakhstan on a Soyuz rocket as part of his UK Space agency ‘Principia’ mission to the International Space Station (ISS). Two Raspberry Pi-powered Astro Pi Mark 1 computers were waiting for him in the Columbus module of the ISS, ready to be set up for an experimental education activity called “Astro Pi”.

The European Astro Pi Challenge, an ESA Education project run in collaboration with the Raspberry Pi Foundation, and supported by national ESEROs, has been running every year since. The challenge now features two Python coding ‘missions’ that offer young people the amazing opportunity to write a short computer program to send to run on the ISS: Mission Zero and Mission Space Lab.

Tens of thousands of young people participate in Astro Pi annually, reaching over 160,000 participants since 2015. On 15 December this year, Tim Peake and some of the Astro Pi team were at the Science Museum London running Mission Zero workshops for visiting school groups to create their own pixel art programs to send into space.

“Setting up the Astro Pi computers on the ISS for those first experiments in 2015 was just the beginning of something truly incredible — it’s amazing to see how much impact the programme has had since then! I hope Astro Pi inspires thousands more young people to code, learn about space technology, and feel empowered to reach for the stars in their own careers.” – Tim Peake, former ESA Astronaut

As the challenge has matured, its reach has increased, with over 25,000 participants every year since 2021. Young people from all 27 ESA member and associate states have sent their code into space, with 25% of mentors returning to the challenge year after year.

“I think Mission Zero is a way of connecting not only to a worldwide group of learners, but also to explorers, future scientists, and future astronauts. To see them as part of a larger community and not just an activity or assignment that they have to do in class. They discover their own abilities and potential, and exercise their creativity in a very low-stakes environment and then to see it come to life in that global way is extremely valuable.” – Mission Zero mentor 

Mission Zero has proved to be a great way to engage girls in computing and tech, with an average of 44% of participants identifying as female. This is well above the national averages for other STEM subjects in many countries.

What attracts many teams of young people to Mission Space Lab is the chance to capture data and images from the SenseHats and High Quality Cameras on the Astro Pi computers. This year the Astro Pis will be positioned in the World Observation Research Facility (WORF) window, which means teams can hope for some fantastic, high-quality Earth-observation images with a full field of view. Each team that achieves Flight Status will receive the images and data their program captures.

The next generation of space explorers

Astro Pi is one of the most inspirational coding activities that young people can do and gives the exciting chance to reach beyond the boundaries of what they may have thought possible. In the 2024–25 impact report, mentors reported that the young people participating were highly motivated by the possibility of having their code run on the ISS.

“Honestly, the idea that a kid can send their own code to space is just mind-blowing. It really makes you rethink what ‘possible’ even means.” – Jeanna, Astro Pi enthusiast

Participation increases skills, confidence and motivation for further exploration in coding, digital making and STEM subjects. 

  • 83% of Mission Zero mentors agreed that young people increased their skills and confidence in computing and digital making due to their participation
  • 91% of mentors told us that young people who successfully wrote code for Mission Space Lab were likely, or very likely, to participate in computing and digital making challenges in the future

Join us in this year’s anniversary challenge to celebrate a decade of sending young people’s code into space – and receive some limited edition certificates. You can find out everything you need to participate or to mentor a team at astro-pi.org.

Choose your space mission

Not sure where to start? The European Astro Pi challenge, or Astro Pi for short, has two missions that young people can participate in depending on their coding abilities. Both Missions use Python programming to create short computer programs that will be run on the ISS. Which one will you choose? 

Mission Zero: Your pixel art in space

Mission Zero offers a chance for young people to create a nature-inspired piece of pixel art using Python and have it displayed for astronauts to see on special Raspberry Pi computers, called Astro Pis, aboard the ISS. We wanted to share some of our favourite pixel art creations from last year’s mission — you can find them as new examples in our project guide. If your team needs some inspiration to get started, they can choose to recreate or remix one of these examples, or create their own.

The deadline for Mission Zero submissions is 23 March 2026.

Mission Space Lab: Become a space scientist

For our more experienced coders, Mission Space Lab returns with a real-world scientific task: calculate the speed of the International Space Station as accurately as possible. Teams of between two and six  young people will write a Python program that collects data from the Astro Pi computers on the ISS to perform this calculation. 

This year, we’ve made some user improvements to the Astro Pi Replay tool, which allows teams to test their programs with a real-time simulation using historical ISS data and images. This updated online tool makes it even easier to see how your program would perform in orbit and troubleshoot any errors. 

The submission deadline for Mission Space Lab is 16 February 2026.

Celebrating a decade of your programs in space

For ten years, the European Astro Pi Challenge has given young people the unique opportunity to explore computer science and space. Ever since the first Astro Pis arrived on the ISS with ESA astronaut Tim Peake on his Principia Mission, young people have been writing programs to run in space. This year, we’re excited to see what new ideas you have for your pixel arts creations, and how you approach the speed challenge.

Code, confidence, and community: A look back at Astro Pi 2024–25

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/code-confidence-and-community-a-look-back-at-astro-pi-2024-25/

Taking part in the European Astro Pi Challenge builds young people’s confidence and motivates them to try further digital making and programming activities, according to their mentors. The challenge, a European Space Agency (ESA) Education project run in collaboration with the Raspberry Pi Foundation, offers young people the amazing opportunity to write a short computer program to run on Raspberry Pi computers on board the International Space Station (ISS).

An incredible 27,304 young people from 27 countries got involved in Astro Pi 2024–25, with 26,294 succeeding in having their code run in space across the two challenge activities, Mission Zero and Mission Space Lab. As in past years, we’ve asked mentors and their teams about their experience and the impact participating had on them. So what did they say?

How we listened to feedback

To find out what worked well, what we could improve, and the impact Astro Pi has had on young people’s lives this year, we encouraged mentors to complete a survey after teams submitted their computer programs. We also ran focus group discussions to deepen our understanding. A huge thank you to the 99 Mission Zero and 26 Mission Space Lab mentors who completed our surveys, and the five mentors who participated in our focus groups.

What is working well

Low stakes but high impact

Mentors believe that Astro Pi is a great opportunity for young people to build their coding skills and knowledge of STEM concepts. Close to 80% of mentors for Mission Zero and 90% for Mission Space Lab agreed that these outcomes were being achieved for the young people in their teams. Mentors also appreciated that while the programme had real-world application, the learning experience was relaxed and low pressure.

Many of our young participants come from areas of educational disadvantage or traditionally underrepresented groups where confidence with technology and STEM subjects can be low. Mentors reported that the programme empowers young people, increasing their confidence with computing and digital making, and helping them connect with a wider community of learners from around the world. 

“They [young people] come from complicated environments and sometimes their confidence is very low. They don’t believe in themselves and this [Mission Zero challenge] really empowers them.” — Mission Zero mentor

“I think having a space mission, having Mission Zero is a way of connecting not only to a worldwide group of learners, but also explorers, future scientists, future astronauts. To see them as part of a larger community, not just an activity or assignment that they have to do in class. They discover their own abilities and potential, and exercise their creativity in a very low stakes environment… and then to see it come to life in that global way I think is extremely valuable.” — Mission Zero mentor

This increased confidence also encourages young people to take on other opportunities. 78% of Mission Zero mentors and 96% of Mission Space Lab mentors believe that it is likely that their students will participate in other coding and digital making challenges in the future.

Space is cool!

The connection to space and the ISS continues to be a strong motivator, not just for young people but also mentors and other peers. In our survey, 90% of mentors in Mission Zero and 92% in Mission Space Lab reported that the young people participating were highly motivated by the possibility of having their code run on the ISS. In focus groups, mentors highlighted how the excitement of working on a space project extended to them and other adults too.

“They’ve always really enjoyed the sheer fact that you get to send stuff into space because it is really cool.” — Mission Zero mentor

“You know, even the adults I tell about this say, ‘oh, that sounds amazing. Can I do it?’ I go, ‘No, you’re too old. I’m too old.’” — Mission Zero mentor

“We want our code to run in space! We are fascinated by discovery and the opportunity to contribute to a real science experiment on the ISS.” — Mission Space Lab mentor

The resources and guidance are useful

We know how crucial mentors are to the success of Astro Pi. Mentors come from diverse backgrounds and we are committed to making sure they feel prepared and supported. We were thrilled to hear that over 90% of Mission Zero mentors and 80% of Mission Space Lab mentors found the Astro Pi resources useful.

“I had no skills but the support proved to be excellent” — Mission Zero mentor

“Step-by-step instructions were excellent and really clear. Very easy to follow.” — Mission Zero mentor

For Mission Space Lab, the more technical activity, we’ve been working on providing additional support. In 2024–25 we introduced a new online simulator tool for teams to test their programs with historical ISS data. Mentors found the tool to be helpful, allowing them to troubleshoot their code.

What could be improved?

While we celebrate the successes, we’re always keen to understand how we can improve the programme.

As in previous years, mentors reported that young people whose computer programs passed the eligibility criteria and ran on the ISS (or “achieved flight status”, as we call it) benefited most from the experience. While 12% more Mission Space Lab teams achieved flight status this year compared to last year, some registered teams still did not submit programs. 

To understand why, we surveyed mentors who had registered but who did not then submit computer programs. In the 55 responses, the main reasons given were a shortage of time due to other school commitments, and their teams finding the challenge difficult. 

Some survey respondents suggested a need for more simplified, step-by-step instructions for less experienced learners. Additionally, a few teams faced technical issues with the online portal and the testing tool.

Thank you to all the mentors who provided their honest feedback. We’ve read and considered all of it and will use it to make Astro Pi even better in the future.

Astro Pi will be launching for its 10th year on Monday, 8 September 2025. We’ve been working on making it easier than ever to take part in both missions and are looking forward to supporting you and your teams in getting your code into space. If you’re interested in taking part, sign up to our newsletter and get the latest news and information about our resources for this year’s missions.

Astro Pi 2024/25: Another stellar year of space education concludes

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/astro-pi-2024-25-another-stellar-year-of-space-education-concludes/

We’re thrilled to celebrate yet another incredible year of young people reaching for the stars, as the European Astro Pi Challenge 2024/25 draws to a close. Teams from across Europe and ESA Member States are now receiving their well-deserved certificates and data from the International Space Station (ISS). It’s been a truly inspiring year, showcasing the phenomenal talent and dedication of young coders and scientists.

The European Astro Pi Challenge is an ESA Education project run in collaboration with us here at the Raspberry Pi Foundation. It offers young people the amazing opportunity to conduct scientific investigations in space by writing computer programs that run on Raspberry Pi computers on board the ISS, called Astro Pis.

There‘s a lot to celebrate from this year’s Astro Pi, so let’s take a look at some of the highlights for each of our inspiring Missions: Mission Zero and Mission Space Lab.

Mission Zero: Inspiring coding, creativity, and inclusion

Mission Zero reached more young people than ever before in 2024/25, with 25,405 young people participating in 17,285 teams. After passing the rigorous testing and moderation processes, an amazing 17,109 teams (25,210 young people) were successful in getting their programs to run on the ISS. 

One of the great things about Mission Zero is that we see a good gender balance in participation. This year, 44% of participants identified as “female” and 4% as “prefer to self-describe”, “prefer not to say”, or “other”. This means that Mission Zero has achieved a more balanced gender representation than is typically seen in computing subjects, where the ratio is around 20:80 girls to boys.

Mission Space Lab: More teams have their programs run in space

Mission Space Lab gives young people the opportunity to calculate the speed of the ISS in orbit using sensor and camera data collected from the Astro Pis on board the ISS. This year, 1859 young people in 552 teams participated in Mission Space Lab. Notably, 309 Mission Space Lab teams, or 95% of submissions, ran their programs on the ISS and are now analysing the data they collected. That’s 73 more teams achieving flight status than in 2023/24, and a total of 1084 young people receiving unique data sets from space and certificates. 

Running a program in space is very different from testing it on the ground. It’s always interesting to see how well your program has performed and how accurate the final output is. Below, you can see a scatter graph of the team estimates produced by their programs. The actual speed of the ISS is no secret: it’s travelling about 7.67 kilometres per second. How have teams performed with the ISS speed task?

Inspiring and impactful

Another highlight from this year has been seeing how impactful participation can be for young people and mentors facilitating the activity. We receive lots of valuable feedback from the Astro Pi community each year, and it’s always heartwarming to hear what your experience has been and how we can improve the challenge. Here are a couple of quotes from the community who took part this year:

Mission Zero mentor: “Having their programs run in space really motivated them to take part because it was an exciting reward and something they wanted to talk about with their friends.”

Parent of a Mission Zero participant: “I was completely inexperienced in Python, but easily managed to help my 7-year-old.”

More Code Clubs participating in 2024/25

It has been great to see lots of Code Clubs taking part in Astro Pi this year, both for Mission Zero and Mission Space Lab. This year, 986 young people from 700 teams did Mission Zero at their Code Club: that’s double the number from 2023/24. Plus, 43 Mission Space Lab teams from Code Clubs took part. That’s 143 young people, or almost double the number compared to the year before. 

We ran two code-alongs for the Code Club community this year, and it is encouraging to see increases for both missions. We will continue to support young people from all settings who want to take part in Astro Pi next year, whether it’s at school, Code Club, or other venues.

Conclusion

In summary, it’s been a great year for Astro Pi. We’ve reached lots of young people through the challenge, met many inspiring mentors, and seen some really positive trends. Plus, all the operations on the space station that make Astro Pi possible went smoothly: when you are running programs in space, that isn’t always the case! 

None of it would have been possible without the tireless efforts of the teachers, mentors, and educators who help run Astro Pi in your communities. From everyone here at Mission Control, thank you. 

If you’d like to tell us how we can provide more support to help you run Astro Pi, please email [email protected].

We’ll be back for more stellar space adventures in coding in September 2025.

The countdown begins! Astro Pi participants to have their programs run in space

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/the-countdown-begins-astro-pi-participants-to-have-their-programs-run-in-space/

This week, young people participating in the European Astro Pi Challenge 2024/25 will have their programs run in space! Astronauts from the European Space Agency (ESA) have been setting up the Astro Pi computers on board the International Space Station (ISS) ready to receive the programs. 

The European Astro Pi Challenge is an ESA Education project run in collaboration with the Raspberry Pi Foundation. It has two strands: Mission Zero, where young people write programs that display pixel art on LED screens on board the ISS, and Mission Space Lab, where more advanced learners attempt to calculate the speed of the ISS by writing programs that gather data from onboard equipment.

This year has already been a great year for the challenge!

Mission Zero reaches more young people than ever

Mission Zero received 17,285 team submissions this year, representing 25,405 young people from ESA member and associate member states. This marks the highest-ever level of participation in Mission Zero since its inception back in 2017. Here at Mission Control, we’re delighted to announce that nearly all the participating teams (17,109 out of 17,285) have achieved ‘flight status’ — meaning that their programs will run in space. 

It’s been great to see so many young people taking part from areas of educational disadvantage too. Through partnerships with youth organisations and community events such as Beyond the Bias and Norwich Science Festival, we’ve seen Mission Zero reach even more young creators from traditionally underrepresented groups.

The 2024/25 Mission Zero project guide featured new coded pixel art examples for teams to remix and reinterpret. Many teams also created their own artworks and animations, with amazing creativity and coding skills on display. We’ll be selecting six submissions from this year to feature as the new code examples in the 2025/26 Mission Zero project guide. Look out for more news on this in the summer.

New highs for Mission Space Lab

Mission Space Lab teams were tasked again this year with writing programs to collect data from cameras and sensors on board the ISS to calculate its speed. We’ve been really pleased to see 562 teams register and 325 submit their programs. This has resulted in an amazing 309 teams being awarded flight status — their programs will each run on the ISS for ten minutes, giving participants the unparalleled opportunity to record sensor data in space and take photos many miles above the Earth. 

More teams have submitted programs and achieved flight status this year than in 2023/24. We believe this uptick is due, in part, to a couple of new additions that have made submissions easier: 

  • Firstly, Mission Space Lab teams can now test their programs online using the Astro Pi Replay Tool. This gives them a chance to see if their program will work on the real Astro Pis on board the ISS by replaying historical data sets captured from previous missions. 

Secondly, teams have been able to use the Picamzero Python library, which makes it easier to use PiCamera2 functionality.

Deployment

Today’s the day when Mission Zero and Mission Space Lab teams with flight status will have their programs sent up to the ISS. Astronauts have been busy setting up the Astro Pi computers ready to receive the programs and putting them into position. Over the next two weeks, the programs will run and the collected data will be sent down from the ISS to Earth.

In June, Mission Zero and Mission Space Lab teams will receive certificates of participation with the exact times their programs ran on the ISS, along with the coordinates of where the ISS was above the Earth. Mission Space Lab teams will also receive a zip file with the data their programs collected. 

None of this would have been possible without the hard work of all the mentors, teachers, and Code Club leaders that organise the teams of young people doing the Astro Pi missions. 

Let’s stay curious, with our eyes upwards on that final frontier!

Looking for ways to keep your creators coding?

While you wait for the next cycle of the European Astro Pi Challenge, there are many other exciting coding opportunities for you and your teams to explore, including:

  • Coolest Projects: Coolest Projects is a free, worldwide showcase where young digital creators share the amazing things they’ve made with technology. There’s an international online showcase as well as in-person events in several countries. Every participant gets certificates and rewards, and projects of any kind and at any level are encouraged.
  • Code Club projects: Our extensive collection of Code Club projects explore Python, Scratch, the BBC micro:bit, and much more — there’s something available for all young people, no matter their level of experience.

We are delighted that new ESA project astronaut Sławosz Uznański will be the ambassador for this year’s Astro Pi Challenge. Sławosz, born in Poland in 1984, has a background in space systems engineering and has conducted research in radiation effects. He recently served as the Engineer in Charge of CERN’s largest accelerator, the Large Hadron Collider.

Mission Zero: Send your pixel art into space

In Mission Zero, young people create beautiful pixel art to display on the Astro Pis’ LED screens. This mission requires no prior experience of Python coding, and it can be completed in around an hour.

To take part, young people design and code pixel art inspired by nature on Earth and beyond, to display on the Astro Pi computers for the astronauts on the ISS to see as they go about their daily tasks.

Using our step-by-step Mission Zero project guide, young people will learn to create simple Python programs in which they will code with variables and use the colour sensors on the Astro Pis to change the background colour in their images. To help your teams create their designs, check out the examples from teams that took part in Mission Zero in 2023/24 in the project guide.

A young person smiles while using a laptop.

Young people can create their Mission Zero programs individually or in teams of up to 4 people, and this year, we have added a save function for young people as they code. This will make it easier for mentors to run Mission Zero over more than one session, and also means that young people can finish their projects at home. They will need to use your classroom code and their team name to load their saved projects. 

Mission Space Lab: Calculate the speed of the ISS

Mission Space Lab asks teams to solve a real-world scientific task in space. It is ideally suited to young people who would like to learn more about space science and stretch their programming skills.

In Mission Space Lab this year, the task for teams of 2 to 6 young people is to calculate the speed at which the International Space Station is travelling — as accurately as possible. Teams need to write a Python program that:

  1. Collects data from the Astro Pi computers’ sensors or cameras about the orientation and motion of the ISS as it orbits the Earth, and
  2. Uses this data to calculate the travel speed

This year we have created a new way for teams to test their programs, with an online version of the Astro Pi Replay tool. All teams need to do is select their program and run it in Astro Pi Replay, which will create a real-time simulation of the program running on the ISS, using historical data and images. Astro Pi Replay will also show program outputs and report errors. This means teams can code their program in their preferred code editor, then test with an internet browser. However, if they wish, teams can still run the Astro Pi Replay tool offline with Thonny.

Young people receive their data from space and Astro Pi certificates

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/young-people-receive-their-data-from-space-and-astro-pi-certificates/

Across Europe and beyond, teams of young people are receiving data from the International Space Station (ISS) this week. That’s because they participated in the annual European Astro Pi Challenge, the unique programme we deliver in collaboration with ESA Education to give kids the chance to write code that runs in space.

In this round of Astro Pi, over 26,400 young people took part across its two missions — Mission Space Lab and Mission Zero — and had their programs run on the Raspberry Pi computers on board the ISS.

Mission Space Lab teams find out the speed of the ISS

In Mission Space Lab, we asked young people to team up and write code to collect data on the ISS and calculate the speed at which the ISS is travelling. 236 teams wrote programs that passed all our tests and achieved flight status to run in space. And not only will the Mission Space Lab teams receive their participation certificates this week — they’ll also receive the data their programs captured on the ISS.

Many teams chose a feature extraction method to calculate the ISS’s speed, identifying two points on Earth from which to calculate the distance the ISS travelled over time. Using this method means using the high-quality camera on the Astro Pi computer to take some fantastic photos of Earth from the ISS’s World Observation Research Facility (WORF) window. Teams will receive these photos soon, which are unique views of Earth from space.

The actual speed that the ISS is travelling in space while at normal altitude is 7.66km/s. Its altitude can affect the speed, so it can vary, but the ISS’s boosters fire up if it dips too low.

To help teams with writing programs that can adapt to some of these variances, and to show them the type data they can collect, we gave them a programming tool we call Astro Pi Replay. Using this tool, teams can simulate how their program would run on the Astro Pi computers up in space.

This is the first time we asked Mission Space Lab teams to focus on a particular scientific question. So how did they do? The graph below shows some of the speeds that teams’ programs estimated.

As you can see, a variety of speeds were estimated, but the average is fairly close to the ISS’s actual speed. Teams did a great job trying to solve the question and working like real space scientists. Once they receive their data this week, they can check how accurate their speed estimate was.

Mission Zero pixel art lights up astronauts’ daily tasks 

In Astro Pi Mission Zero, a coding activity suitable for beginners, 16,039 teams of young people created code to make pixel art inspired by nature. Nearly half (44%) of the 24,409 participants were girls! 15,942 of the Mission Zero teams had their code run on the ISS after we checked that it followed the rules.

Mission Zero Submissions

Every team whose program ran on the ISS — with their pixel art showing for the astronauts to see as they worked — will receive certificates with the time, date, and location coordinates of their Mission Zero run. 

We’ve been so impressed with this year’s pixel art creations that we’ve picked some as new examples for next year’s Mission Zero coding guide. That means young people will be able to choose one of a few pixel images to start with and recreate or remix them for their program. More info on that is coming soon, sign up to the Astro Pi newsletter to not miss it.

Let’s get ready for September

Thank you and congratulations to everyone who took part in the missions this year, and our special thanks to all the amazing educators who ran Astro Pi activities with young people.

For us, there is much to reflect on and celebrate from this year’s challenge. We’ve had the chance to run Mission Zero with young people in person and identify a few changes to help make the activity easier. As Mission Space Lab now involves simulating programs running on the ISS with our new Astro Pi Replay tool, we’ll be exploring how to improve this as well.

We hope to engage lots of previous and new participants in the Astro Pi Challenge when it starts up again in September. Sign up for the newsletter on astro-pi.org to be the first to hear about the new round.

Young people’s Astro Pi code is sent to the International Space Station

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/young-peoples-astro-pi-code-is-sent-to-the-international-space-station/

Young people taking part in the European Astro Pi Challenge are about to have their computer programs sent to the International Space Station (ISS). Astro Pi is run annually in collaboration by us and ESA Education, and offers two ways to get involved: Mission Zero and Mission Space Lab.

This year, over 25,000 young people from across Europe and eligible ESA Member States are getting their programs ‘uplinked’ to the Astro Pi computers aboard the ISS, where they will be running over the next few weeks. 

Mission Zero teams send their art into space

Mission Zero is an exciting activity for kids with little or no experience with coding. We invite young people to create a Python program that displays an 8×8 pixel image or animation. This program then gets sent to the ISS, and each pixel art piece is displayed for 30 seconds on the LED matrix display of the Astro Pi computers on the ISS.

We picked the theme ‘fauna and flora’ as the inspiration for young people’s pixel art, as it proved so popular last year, and we weren’t disappointed: this year, 24,378 young people submitted 16,039 Mission Zero creations!  

We’ve tested every program and are pleased to announce that 15,942 Mission Zero programs will be sent to run on the ISS from mid May. 

Once again, we have been amazed at the wonderful images and animations that young people have created. Seeing all the images that have been submitted is one of the most enjoyable and inspiring things to do as we work on the Astro Pi Challenge. Here is a little selection of some of our favourites submitted this year:

Varied approaches: How different teams calculate ISS speed

For Mission Space Lab, we invite more experienced young coders to take on a scientific challenge: to calculate the speed that the ISS orbits Earth. 

Teams are tasked with writing a program that uses the Astro Pis’ sensors and visible light camera to capture data for their calculations, and we have really enjoyed seeing the different approaches the teams have taken. 

The mark 2 Astro Pi units spin in microgravity on the International Space Station.

Some teams decided to calculate the distance between two points in photos of the Earth’s surface and combine this with how long it took for the ISS to pass over the points to find the speed. This particular method uses feature extraction and needs to account for ground sampling distance — how many square metres are represented in one pixel in an image of the ground taken from above — to get an accurate output.  

We’ve also seen teams use data from the gyroscope to calculate the speed using the angle readings and photos to get their outputs. Yet other teams have derived the speed using equations of motion and sampling from the accelerometer.

An example of features of the earth’s surface being matched across two different images.
Feature extraction example taken from images captured by the Astro Pis

All teams that took multiple samples from the Astro Pi sensors, or multiple images, had to decide how to output a final estimate for the speed of the ISS. Most teams opted to use the mean average. But a few teams chose to filter their samples to choose only the ‘best’ ones based on prior knowledge (Bayesian filtering), and some used a machine learning model and the Astro Pi’s machine learning dongle to select which images or data samples to use. Some teams even provided a certainty score along with their final estimate.

236 Mission Space Lab teams awarded flight status

However the team choses to approach the challenge, before their program can run on the ISS, we need to make sure of a few things. For a start, we check that they’ve followed the challenge rules and meet the ISS security requirements. Next, we check that the program can run without errors on the Astro Pis as the astronauts on board the ISS can’t stop what they’re doing to fix any problems. 

So, all programs submitted to us must pass a rigorous testing process before they can be sent into space. We run each program on several replica Astro Pis, then run all the programs sequentially, to ensure there’s no problems. If the program passes testing, it’s awarded ‘flight status’ and can be sent to run in space.

The Astro Pi computers inside the International Space Station.

This year, 236 teams have been awarded flight status. These teams represent 889 young people from 22 countries in Europe and ESA member states. The average age of these young people is 15, and 27% of them are girls. The UK has the most teams achieving flight status (61), followed by the Czech Republic (23) and Romania (22). You can see how this compares to last year and explore other breakdowns of participant data in the annual Astro Pi impact report.  

Our congratulations to all the Mission Space Lab teams who’ve been awarded flight status: it is a great achievement. All these teams will be invited to join a live online Q&A with an ESA astronaut in June. We can’t wait to see what questions you send us for the astronaut.

A pause to recharge the ISS batteries 

Normally, the Astro Pi programs run continuously from the end of April until the end of May. However, this year, there is an interesting event happening in the skies above us that means that programs will pause for a few days. The ISS will be moving its position on the ‘beta angle’ and pivoting its orientation to maximise the sunlight that it can capture with its solar panels. 

A picture of the International Space Station.
The International Space Station

The ISS normally takes 90 minutes to complete its orbit, 45 minutes of which is in sunlight, and 45 minutes in darkness. When it moves along the beta angle, it will be in continual sunlight, allowing it to capture lots of solar energy and recharge its batteries. While in its new orientation, the ISS is exposed to increased heat from the sun so the window shutters must be closed to help the astronauts stay cool. That means taking photos of the Earth’s surface won’t be possible for a few days.

What next?

Once all of the programs have run, we will send the Mission Space Lab teams the data collected during their experiments. All successful Mission Zero and Mission Space Lab teams and mentors will also receive personal certificates to recognise their mission completion.

Congratulations to all of this year’s Astro Pi Challenge participants, and especially to all successful teams.

Get ready for Mission Space Lab with our new simulation tool

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/get-ready-for-mission-space-lab-with-our-new-simulation-tool/

Since November, registration is open for Mission Space Lab, part of the European Astro Pi Challenge 2023/24. The Astro Pi Challenge is an ESA Education project run in collaboration with us here at the Raspberry Pi Foundation that gives young people up to age 19 the amazing opportunity to write computer programs that run on board the International Space Station (ISS). It is free to take part and young people can participate in two missions: Mission Zero, designed for beginners, and Mission Space Lab, designed for more experienced coders.

Two young people working together on a tech project.

This year, Mission Space Lab has a brand-new format. As well as introducing a new activity for teams to work on, we have created new resources to support teams and mentors, and developed a special tool to help teams test their programs. 

A young person writes Python code.

A big motivator for these changes was to make the activity more accessible and enable more young people to have their code run in space. Listening to feedback from participants and mentors, we are creating the opportunity for even more teams to submit programs that run on the ISS this year, by offering a specific activity and providing more extensive support materials.

A scientific task

For this year’s mission, ESA astronauts have given teams a specific scientific task to solve: to calculate the speed that the ISS is travelling as it orbits the Earth. People working in science often investigate a specific phenomenon or try to solve a particular problem. They have to use their knowledge and skills and the available tools to find ways to answer their research question. For Mission Space Lab, teams will work just like this. They will look at what sensors are available on the Astro Pi computers on board the ISS, develop a solution, and then write a Python program to execute it. To test their program, they will use the new Astro Pi Replay software tool we’ve created, which simulates running their program on board the ISS.

The two Astro Pi computers.

To help teams and mentors take part in Mission Space Lab, we are providing a variety of supporting materials:

  • Our mentor guide has everything mentors need to support their teams through Mission Space Lab, including guidance for structuring the mission and tips to help teams solve problems.
  • Our creator guide helps young people design and create their programs. It provides information and technical instructions to help young people develop their coding skills and create a program that can be run on the Astro Pis on board the ISS.
  • We have created an ISS speed project guide that shows an example of how the scientific task can be solved using photos captured by the Astro Pi’s camera.

We have also run virtual sessions to help mentors and teams familiarise themselves with the new Mission Space Lab activity, and to ask any technical questions they might have. You can watch the recordings of these sessions on YouTube: 

The Astro Pi Replay tool

Astro Pi Replay is a new simulation tool that we have developed to support Mission Space Lab teams to test their programs. The tool simulates running programs on the Astro Pi computers on board the ISS. It is a Python library available as a plug-in to install in the Thonny IDE where teams write their programs. Thanks to this tool, teams can develop and test their programs on any computer that supports Python, without the need for hardware like the Astro Pi units on board the ISS.

The Astro Pi Replay tool works by replaying a data set captured by a Mission Space Lab team in May 2023. The data set includes readings from the Astro Pi ‘s sensors, and images taken by its visible-light camera like the ones below. Whenever teams run their programs in Thonny with Astro Pi Replay, the tool replays some of this historical data. That means teams can use the historical data to test their programs and calculations.

A photo the Irish Sea with the coastlines of the UK and Ireland

A photo the Coastline of Southern Egypt and the Red Sea
The coastline of southern Egypt and the Red Sea

One of the benefits of using this simulation tool is that it gives teams a taste of what they can expect if their program is run on the ISS. By replaying a sequence of data captured by the Astro Pis in space, teams using sensors will be able to see what kind of data can be collected, and teams using the camera will be able to see some incredible Earth observation images.

If you’re curious about how Astro Pi Replay works, you’ll be pleased to hear we are making it open source soon. That means you’ll be able to look at the source code and find out exactly what the library does and how.

Get involved

Community members have consistently reported how amazing it is for teams to receive unique Earth observation photos and sensor data from the Astro Pis, and how great the images and data are to inspire young people to participate in their computing classes, clubs, or events. Through the changes we’ve made to Mission Space Lab this year, we want to support as many young people as possible to have the opportunity to engage in space science and capture their own data from the ISS. 

If you want a taste of how fantastic Astro Pi is for learners, watch the story of St Joseph’s, a rural Irish school where participating in Astro Pi has inspired the whole community.

Submissions for Mission Space Lab 2023/24 are open until 19 February 2024, so there’s still time to take part! You can find full details and eligibility criteria at astro-pi.org/mission-space-lab.

Explore space science and coding with Astro Pi Mission Space Lab

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/european-astro-pi-challenge-mission-space-lab-2023-24/

Today we’re calling all young people who are excited to explore coding and space science, and the mentors who want to support and inspire them on their journey. Astro Pi Mission Space Lab is officially open again, offering young people all over Europe the amazing chance to have their code for a science experiment run in space on the International Space Station (ISS).

With this year’s Mission Space Lab, astronauts from the European Space Agency are setting young people a task: to write a computer program that runs on the ISS and calculates the speed at which the ISS is orbiting planet Earth. Participation in Mission Space Lab is completely free.

Here’s ESA astronaut candidate Rosemary Coogan to introduce this year’s mission:

The mission: Calculate the speed of the ISS

Mission Space Lab invites young people up to age 19 to work in teams of 2 to 6 and write a Python program for the Astro Pi computers on board the ISS to collect data and calculate the speed at which the ISS is travelling. 

Your role as a mentor is to support teams as they design and create their program — with our free guidance resources to help you and your young creators.

I want to sign up as a mentor

We want as many young people as possible to have the chance to take part in Mission Space Lab, so the way in which teams solve the task set by the ESA astronauts can be different depending on the experience of your team:

  • Beginner programmers can follow the guided project we provide (more info below) to write their program.
  • Teams with more programming experience can get creative to come up with their own innovative solution and calculate the speed of the ISS as accurately as possible.

The Astro Pis are two Raspberry Pi computers stationed on the ISS, each equipped with a High Quality Camera, a Sense HAT add-on board with a number of sensors, and a Coral machine learning accelerator. Each Astro Pi has a hard casing designed especially for space travel.

All Mission Space Lab participants whose programs run on the ISS will receive a certificate recognising their achievement, and they’ll get the chance to attend a Q&A webinar with an ESA astronaut. Teams also receive back data from the ISS based on their Mission Space Lab programs, for example photos or sensor measurements. That means you’ll have the option to explore and use that data in follow-on activities with your young people.

Support for you to get started with Mission Space Lab

We are providing lots of supporting materials to help you and your team with Mission Space Lab:

  • A new Mission Space Lab mentor guide helps you assemble and support teams of young people who want to take part. It gives you as a mentor everything you need to answer your team’s questions and help them solve problems. It also includes tips on how to structure the Mission for your team. So young and your young people can make the most of Mission Space Lab, we suggest you run a series of sessions where your team can learn about the ISS, think about how they could use the different Astro Pi sensors, and design and create a program. The guide shows you how to help them use a design thinking approach during the Mission and develop problem solving and collaboration skills that are very important for careers in tech.
  • The Mission Space Lab creator guide helps young people design and create their Python programs. It contains all of the information they need to write a program that can be run on the Astro Pis. It includes discussion points for the team’s planning and design process. The technical instructions support young people to create a program that accomplishes its goal in the allocated runtime of 10 minutes.
  • We’re also providing a ISS speed project guide that shows one way for teams to complete the Mission Space Lab task: writing a program that calculates the ISS speed using photos taken by the Astro Pi’s camera. 

Mission Space Lab is open for submissions from today, 6 November 2023, until 19 February 2024.

Participation in Astro Pi is open to young people up to age 19 in ESA Member States (see the Astro Pi website for eligibility details).

Astro Pi Mission Zero opens today

In Astro Pi Mission Zero, young people write a simple Python program to take a reading using a sensor on one of the ISS Astro Pi computers and display a personalised pixel art image for the astronauts on board the ISS. They can take part by themselves or as coding teams.

Logo of Mission Zero, part of the European Astro Pi Challenge.

The theme for Mission Zero 2023/24 is ‘fauna and flora’: young people are invited to program pixel art images or animations of animals, plants, or fungi to display on the Astro Pi computers’ LED pixel screen and remind the astronauts aboard the ISS of Earth’s natural wonders.

Young people’s amazing experiments in space: Astro Pi Mission Space Lab 2022/23

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/astro-pi-mission-space-lab-2022-23-results/

Celebrate another year of young people’s computer programs in space with us: today we and our collaborators at the European Space Agency can finally announce the winning and highly commended teams in this year’s Astro Pi Mission Space Lab.

Mission Space Lab: Young people’s experiments in space

In Mission Space Lab, teams of young people work together to create computer programs for scientific experiments to be carried out on the International Space Station. The programs they design and create run on the two Astro Pi computers: space-adapted Raspberry Pis with cameras and a range of sensors.

Teams’ programs were deployed on the ISS during May and ran for up to 3 hours, collecting data for their experiments. Once we’d sent the teams their data, they started analysing it in order to write their Phase 4 reports. To identify patterns and phenomena they were interested in, many teams chose to compare their data with other sources.

We were especially excited to see the results from the experiments this year, particularly given that the upgraded Astro Pi units with their High Quality Cameras were positioned in a new observation window (WORF) on the ISS. This allowed teams to capture high-resolution images with a much wider field of view.

What have Mission Space Lab teams investigated this year?

We feel very privileged to see the culmination of the team’s experiments in their final reports. So let’s share a few highlights from this year’s experiments:

Team Aretusa from Sicily explored the effects of climate change by cross-referencing the images they captured with the Astro Pis with historical images from Google Earth. They used Near Infrared photography to capture images, and NDVI (Normalised Difference Vegetation Index) image processing in their analysis. Below you can see that they have compared data of Saudi Arabia from 1987 to 2023, showing increasing levels of vegetation grown in attempts to restore degraded land.

Images taken from space of plant cover in Saudi Arabia.

Team Barrande from the Czech Republic trained AI models on images they gathered to identify topographical features of Earth. Their Mission Space Lab program used the Astro Pi computer’s machine learning dongle to train one AI model in real time. Later, the team also used the collected images to train another model back on Earth. Comparing the outputs of the two models, the team could tell how well the models had identified different topographical features. The below selection shows an image the team’s experiment captured on the left, the same image after processing by the AI model trained on the Astro Pi computer in the middle, and the image processed by the AI model trained on Earth.

Three images showing how two image classifier machine learning models perform in comparison.

Team DAHspace from Portugal measured the intensity of the Earth’s magnetic field along the orbit path of the ISS. Using the magnetometer on the Astro Pi, their experiment recorded data allowing the team to track changes of intensity. The team mapped this data to the ISS’s coordinates, showing the difference in the Earth’s magnetic field between the North Pole (points 1 and 2 on the chart below) and the South Pole (points 3 and 4).

Magnetic field data plotted against latitude.

And the winning teams are…

We and our collaborators at ESA Education have been busy reviewing all of the reports to assess the scientific merit, use of the Astro Pi hardware, experiment design, and data analysis. The ten winning teams come from schools and coding clubs in 11 countries. We are sending each team some cool space swag to recognise their achievement.

Congratulations to all 2022/23 participants

Huge congratulations to every team that participated in Astro Pi Mission Space Lab. We hope you found it fun and inspiring to take part. 

A big thank you to everyone who has been involved in the European Astro Pi Challenge this year. An amazing 24,850 young people from 29 countries had their programs run in space this year. We can’t wait to do it all again starting in September.

And it’s not just us saying thanks and well done — here’s a special message from ESA astronaut Matthias Maurer:

Looking forward to the next Astro Pi Challenge

On 18 September 2023, we’ll launch the European Astro Pi Challenge for 2023/24. Mission Zero will open in September, and we’ll announce exciting news about Mission Space Lab in September too.

Young people designed 15,000 images for astronauts in Astro Pi Mission Zero 2022/23

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/15000-young-people-astro-pi-mission-zero-2022-23/

In the Columbus module of the International Space Station (ISS), there are two Astro Pi computers called Marie Curie and Nikola Tesla. These computers run the programs young people create as part of the annual European Astro Pi Challenge.

A young person takes part in Astro Pi Mission Zero.

For this year’s Astro Pi Mission Zero, young people sent us over 15,000 programs to show the ISS astronauts colourful images and animations of animals and plants on the Astro Pi displays and remind them of home.

A space mission inspired by nature

Mission Zero is a free beginners’ coding activity. It gives young people the unique opportunity to follow our step-by-step guide to write a simple program in Python that can run in space on the ISS orbiting planet Earth.

The Mission Zero activity this year was to write code to use the Astro Pi’s colour sensor to measure the lighting conditions in the Columbus module, and to then use that measurement to set a colour in an image or animation on the Astro Pi’s 8×8 LED display. We invited young people to design images of fauna and flora to give the astronauts on board the ISS a reminder of the beautiful creatures, plantlife, and landscapes found on planet Earth.

The Mission Zero activity is ideal for learners trying text-based programming for the first time. It covers some key programming concepts, including variables, sequence, and iteration.

Tens of thousands of young people had their programs run in space

This year we received 15,551 Mission Zero programs, and after carefully checking them against the entry and safety criteria, we were able to run 15,475 programs. They were sent to us by 23,605 learners working in teams or independently, and 10,207 of this year’s participants were girls.

This year the most Mission Zero programs came from young people in the UK, followed by Spain, France, Italy, and Greece. Lots of different organisations supported young people to take part, including publicly funded primary and secondary schools, as well as educator- and volunteer-led Code Clubs and CoderDojos we support. 

We’re celebrating the many different people involved in this year’s mission with a mosaic of the Mission Zero logo made up of lots of the inspiring designs participants sent us. You can explore an interactive version of the image too!

Over 15,000 teams of young people from across Europe had their computer programs run on board the International Space Station (ISS) this month as part of this year’s European Astro Pi Challenge.

Astro Pi is run in collaboration by us and ESA Education, and offers two ways to get involved: Mission Zero and Mission Space Lab.

Mission Zero: Images of Earth’s fauna and flora in space 

Mission Zero is the Astro Pi beginners’ activity. To take part, young people spend an hour writing a short Python program for the Astro Pi computers on the International Space Station (ISS). This year we invited them to create an 8×8 pixel image or animation on the theme of fauna and flora, which their program showed on an Astro Pi LED matrix display for 30 seconds.

This year, 23,605 young people’s Mission Zero programs ran on the ISS. We need to check all the programs before we can send them to space and that means we got to see all the images and animations that the young people created. Their creativity was absolutely incredible! Here are some inspiring examples:

Mission Space Lab: Young people’s experiments on the ISS

Mission Space Lab runs over eight months and empowers teams of young people to design real science experiments on the ISS, executed by Python programs they write themselves. Teams choose between two themes: ‘Life in space’ and ‘Life on Earth’.

This year, the Mission Space Lab programs of 1245 young people in 294 teams from 21 countries passed our rigorous judging and testing process. These programs were awarded flight status and sent to the Astro Pis on board the ISS, where they captured data for the teams to analyse back down on Earth.

Mission Space Lab teams this year decided to design experiments such as analysing cloud formations to identify where storms commonly occur, looking at ocean colour as a measure of depth, and analysing freshwater systems and the surrounding areas they supply water to.

Teams will be receiving their experiment data later this week, and will be analysing and interpreting it over the next few weeks. For example, the team analysing freshwater systems want to investigate how these systems may be affected by climate change. What their Mission Space Lab program has recorded while running on the Astro Pis is a unique data set that the team can compare against other scientific data.

The challenges of running programs in space

For the ‘Life on Earth’ category of Mission Space Lab experiments this year, the Astro Pis were positioned in a different place to previous years: in the Window Observational Research Facility (WORF). Therefore the Astro Pis could take photos with a wider view. Combined with the High Quality Camera of the upgraded Astro Pi computers we sent to the ISS in 2021, this means that the teams got amazing-quality photos of the Earth’s surface.

Once the experiments for ‘Life on Earth’ were complete, the astronauts moved the Astro Pis back to the Columbus module and replaced their SD cards, ready for capturing the data for the ‘Life in Space’ experiments.

Running programs in an environment as unique as the ISS, where all hardware and software is put to the test, brings many complexities and challenges. Everything that happens on the ISS has to be scheduled well in advance, and astronauts have a strict itinerary to follow to keep the ISS running smoothly.

As usual, this year’s experiments met with their fair share of challenges. One initial challenge the Astro Pis had this year was that the Canadarm, a robotic arm on the outside of the ISS, was in operation during some of the ‘Life on Earth’ experiments. Although it’s fascinating to see part of the ISS in-shot, it also slightly obscured some of the photos.

Another challenge was that window shutters were scheduled to close during some of the experiments, which meant we had to switch around the schedule for Mission Space Lab programs to run so that all of the experiments aiming to capture photos could do so.

What’s next for Astro Pi?

Well done to all the young people who’ve taken part in the European Astro Pi Challenge this year.

  • If you’ve mentored young people in Mission Zero, then we will share their unique participation certificates with you very soon.
  • If you are taking part in Mission Space Lab, then we wish you the best of luck with your analysis and final reports. We are excited to read about your findings.

Mission Space Lab 2022-23 – 294 teams achieved Flight Status

Post Syndicated from Fergus Kirkpatrick original https://www.raspberrypi.org/blog/294-teams-experiments-iss-astro-pi-mission-space-lab-2022-23/

In brief

We are excited to share that 294 teams of young people participating in this year’s Astro Pi Mission Space Lab achieved Flight Status: their programs will run on the Astro Pis installed on the International Space Station (ISS) in April.

Mission Space Lab is part of the European Astro Pi Challenge, an ESA Education project run in collaboration with the Raspberry Pi Foundation. It offers young people the amazing opportunity to conduct scientific investigations in space, by writing computer programs that run on Raspberry Pi computers on board the International Space Station.

In depth

To take part in Mission Space Lab, young people form teams and choose between two themes for their experiments, investigating either ‘Life in space’ or ‘Life on Earth’. They send us their experiment ideas in Phase 1, and in Phase 2 they write Python programs to execute their experiments on the Astro Pis onboard the ISS. As we sent upgraded Astro Pis to space at the end of 2021, Mission Space Lab teams can now also choose to use a machine learning accelerator during their experiment time.

In total, 771 teams sent us ideas during Phase 1 in September 2022, so achieving Flight Status is a huge accomplishment for the successful teams. We are delighted that 391 teams submitted programs for their experiments. Teams who submitted had their programs checked for errors and their experiments tested, resulting in 294 teams being granted Flight Status. 134 of these teams included some aspects of machine learning in their experiments using the upgraded Astro Pis’ machine learning accelerator.

The 294 teams to whom we were able to award Flight Status this year represent 1245 young people. 34% of team members are female, and the average participant age is 15. The 294 successful teams hail from 21 countries; Italy has the most teams progressing to the next phase (48), closely followed by Spain (37), the UK (34), Greece (25), and the Czech Republic (25).

Life in space

Teams can use the Astro Pis to investigate life inside ESA’s Columbus module of the ISS, by writing a program to detect things with at least one of the Astro Pi’s sensors. This can include for example the colour and intensity of light in the module, or the temperature and humidity.

81 teams that created ‘Life in space’ experiments have achieved Flight Status this year. Examples of experiments from this year are investigating how the Earth’s magnetic field is felt on the ISS, what environmental conditions the astronauts experience compared to those on Earth directly beneath the ISS as it orbits, or whether the cabin might be suitable for other lifeforms, such as plants or bacteria.

Life on Earth

In the ‘Life on Earth’ theme, teams investigate features on the Earth’s surface using the cameras on the Astro Pis, which are positioned to view Earth from a window on the ISS.

This year the Astro Pis will be located in the Window Observational Research Facility (WORF), which is larger than the window the computers were positioned in in previous years. This means that teams running ‘Life on Earth’ experiments can capture better images. 206 teams that created experiments in the ‘Life on Earth’ theme have achieved Flight Status.

Thanks to the upgraded Astro Pi hardware, this is the second year that teams could decide whether to use visible-light or infrared (IR) photography. Teams running experiments using IR photography have chosen to examine topics such as plant health in different regions, the effects of deforestation, and desertification. Teams collecting visible light photography have chosen to design experiments analysing clouds in different regions, changes in ocean colour, the velocity of the ISS, and classification of biomes (e.g. desert, forest, grassland, wetland).

Testing, testing

Each of this year’s 391 submissions has been through a number of tests to ensure they follow the challenge rules, meet the ISS security requirements, and can run without errors on the Astro Pis. Once the experiments have started, we can’t rely on astronaut intervention to resolve any issues, so we have to make sure that all of the programs will run without any problems. 

This means that the start of the year is a very busy time for us. We run tests on Mission Space Lab teams’ programs on a number of exact replicas of the Astro Pis, including a final test to run every experiment that has passed all tests for the full three-hour experiment duration. The 294 experiments that received Flight Status will take over 5 weeks to run.

97 programs submitted by teams during Phase 2 of Mission Space Lab this year did not pass testing and so could not be awarded Flight Status. We wish we could run every experiment that is submitted, but there is only limited time available for the Astro Pis to be positioned in the ISS window. Therefore, we have to be extremely rigorous in our selection, and many of the 97 teams were not successful because of only small issues in their programs. We recognise how much work every Mission Space Lab team does, and all teams can be very proud of designing and creating an experiment.

Even if you weren’t successful this year, we hope you enjoyed participating and will take part again in next year’s challenge.

What next?

Once all of the experiments have run, we will send the teams the data collected during their experiments. Teams will then have time to analyse their data and write a short report to share their findings. Based on these reports, we will select winners of this year’s Mission Space Lab. The winning and highly commended teams will receive a special surprise.

Congratulations to all successful teams! We are really looking forward to seeing your results.
