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 contact@astro-pi.org.

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

The post Astro Pi 2024/25: Another stellar year of space education concludes appeared first on Raspberry Pi Foundation.

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.

The post The countdown begins! Astro Pi participants to have their programs run in space appeared first on Raspberry Pi Foundation.

Young people can take part in two exciting missions for beginners and more experienced coders, and send their code to run on special Raspberry Pi computers, called Astro Pis, on board the International Space Station (ISS).

Meet the new Astro Pi ambassador, Sławosz Uznański

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.

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.

We can’t wait to see your programs!

The post The European Astro Pi Challenge 2024/25 launches today appeared first on Raspberry Pi Foundation.

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.

How fast does the ISS travel? 

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.

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.

The post Young people receive their data from space and Astro Pi certificates appeared first on Raspberry Pi Foundation.

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. 

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.

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.

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. 

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.

The post Young people’s Astro Pi code is sent to the International Space Station appeared first on Raspberry Pi Foundation.

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 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.

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:

• Astro Pi Mission Space Lab live Q&A

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.

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.

If you have any questions about the European Astro Pi Challenge, please get in touch at contact@astro-pi.org.

The post Get ready for Mission Space Lab with our new simulation tool appeared first on Raspberry Pi Foundation.

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.

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.

There are lots of ways to use sensor data from the Astro Pis to calculate the speed of the ISS, so young people can get creative solving their Mission Space Lab task while learning fascinating facts about physics and the inner workings of the ISS.

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.

Kids’ code in space with the Astro Pi Challenge

In the past few months India’s Chandrayaan-3 mission landed near the Moon’s south pole, NASA’s Parker Solar Probe flew by Venus on its way to the sun, and the SpaceX Crew-7 launched to the International Space Station (ISS), led by ESA astronaut Andreas Mogensen. We’re especially excited about Andreas’ mission because he’s the astronaut who will help to run young people’s Astro Pi programs on board the ISS this year.

As you may know, the European Astro Pi Challenge gives young people the amazing opportunity to conduct scientific experiments in space by writing computer programs for the Astro Pis, special Raspberry Pi computers on board the ISS.

The Astro Pi Challenge is free and offers two missions for young people: Mission Zero is an inspiring activity for introducing kids to text-based programming with Python. Mission Space Lab gives teams of young people the chance to take on a more challenging programming task and stretch their coding and science skills.

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.

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.

By following the guide we provide, kids can complete the Mission Zero coding activity in around one hour, for example during a school lesson or coding club session. No coding experience is needed to take part. Kids can write their code in any web browser on any computer connected to the internet, without special equipment or software.

All young people that meet the eligibility criteria and follow the official Mission Zero guidelines will have their program run in space for up to 30 seconds. They will receive a unique and personalised certificate to show their coding achievement. The certificate will display the exact start and end time of their program’s run, and where the ISS was above Earth in this time period.

Mission Zero 2023/24 opens today and is open until Monday 25 March 2024. It’s very easy to support young people to get involved — find out more on the Astro Pi website:

Astro Pi Mission Space Lab will open soon

In this year’s Astro Pi Mission Space Lab, ESA astronauts are inviting teams of young people to solve a scientific task by writing a Python program.

The Mission Space Lab task is to gather data with the Astro Pi computers to calculate the speed at which the ISS is travelling. This new format of the mission will allow many more young people to run their programs in space and get a taste of space science.

Mission Space Lab will open on 6 November. We will share more information about how young people and mentors can participate very soon.

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.

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.

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).

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.

All of the teams whose Mission Space Lab programs ran on the ISS will receive a certificate signed by ESA astronaut Samantha Cristoforetti. The winning and highly commended teams will also be invited to a live video chat with an ESA astronaut in the autumn.

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.

If you know a young person who might be interested in the Astro Pi Challenge, sign up for the newsletter on astro-pi.org and follow the Astro Pi Twitter account for all the latest announcements about how you can support them to take the unique opportunity to write code to run in space.

The post Young people’s amazing experiments in space: Astro Pi Mission Space Lab 2022/23 appeared first on Raspberry Pi Foundation.

For this year’s Astro Pi Mission Zero, young people sent us over 15000 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 15551 Mission Zero programs, and after carefully checking them against the entry and safety criteria, we were able to run 15475 programs. They were sent to us by 23605 learners working in teams or independently, and 10207 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!

All of the participants whose programs ran on the ISS will be receiving a certificate to recognise their efforts, which will include the time and coordinates of the ISS when their program ran. Programs created by young people from across Europe ran on board the ISS in the final week of May. 

Sign up to the Astro Pi newsletter

If you enjoyed Astro Pi Mission Zero this year, we would be delighted to see you again in the next annual round. If you’re feeling inspired by the images young people have created, we invite you to get involved too. We provide guides and help for all adult mentors who want to support young people to take part, and the step-by-step guide for coding a Mission Zero program in 19 European languages.

The activity of designing an image has been really popular, and we have been super impressed with the creativity of young people’s designs. That’s why we’ll be running Mission Zero in the same format again starting in September.

If you’d like to hear news of the Astro Pi Challenge, please sign up to the newsletter on astro-pi.org: 

We are always interested to hear your feedback about Mission Zero, as a mentor or participant. If you would like to share your thoughts with us, please email enquiries@astro-pi.org. 

PS Look out for some cool news about the Astro Pi computers, which we’ll announce soon on this blog!
