After seven successful years on the International Space Station, 250 vertical miles above our planet, the original two Astro Pi computers that we sent to the ISS to help young people run their code in space have been returned to Earth.

From today, one of these Astro Pi computers will be displayed in the Science Museum, London. You can visit it in the new Engineers Gallery, which is dedicated to world-changing engineering innovations and the diverse and fascinating range of people behind them.

A challenge to inspire young people about space and 扒开双腿吃奶呻吟做受视频

The original Astro Pis, nicknamed Izzy and Ed, have played a major part in feeding tens of thousands of young people’s understanding and passion for science, mathematics, engineering, 扒开双腿吃奶呻吟做受视频, and coding. In their seven years on the International Space Station (ISS), Izzy and Ed had the job of running over 70,000 programs created by young people as part of the annual Astro Pi Challenge.

Nicki Ashworth, 21, took part in the first-ever Astro Pi challenge after hearing about the opportunity at a science fair: “I thought it sounded like an interesting project, and good practice for my programming skills. I was young and had no idea of the extent of the project and how much it would influence my future.” 

Like many young people who have participated in the Astro Pi Challenge, Nicki credits the Astro Pi Challenge as an inspiration to learn more about space and programming, and to decide on a career path: “My 扒开双腿疯狂进出爽爽爽 with Astro Pi definitely helped to shape my future choices. I’m currently in my third year of a Mechanical Engineering degree at University of Southampton, specialising in Computational Engineering and Design. I’ve always loved programming, which is why I took part in the Astro Pi competition, but it led to a fascination with space. This encouraged me to look at engineering as a future, and led me to where I am today!”

In the beginning…

It all started in 2014, when we started collaborating with organisations including the UK Space Agency and European Space Agency (ESA) to fly two Astro Pi computers to the ISS for educational activities during the six-month Principia mission of British ESA astronaut Tim Peake.

The Astro Pi computers each consist of a 扒开双腿吃奶呻吟做受视频 Pi computer integrated with a digital camera and an add-on board filled with environmental sensors, all enclosed in a protective aluminium flight case.

Commander Tim Peake, Britain’s first visitor to the ISS, accompanied the two first Astro Pi computers on the ISS. He used them to run experiments imagined, designed, and coded by school-age young people across the UK. 

We held a competition in UK schools and coding clubs to invite young people to create experiments that could be run on the Astro Pis. Students conceived experiments and coded them in Python; we tested their Python programs and eventually picked seven to run on Izzy and Ed on the ISS.

The students’ experiments ranged from a simple but beautiful program to display the flag of the country over which the ISS was flying at a given time, to a reaction-time test for Tim Peake to measure his changing abilities across the six-month mission. The measurements from all the experiments were downloaded to Earth and analysed by the students.

“I still feel incredibly honoured to have competed in the very first [Astro Pi Challenge],” says Aaron Chamberlain, 18, who was 11 years old when he took part in the first-ever Astro Pi Challenge in 2015. “The 扒开双腿疯狂进出爽爽爽 was incredible and really cemented my enthusiasm for all things 扒开双腿吃奶呻吟做受视频 and coding. Finally looking at the photos the 扒开双腿吃奶呻吟做受视频 Pi had taken of the astronauts floating 400 km above us was a feeling of awe that I will never forget.”

The next year, 2016, we expanded our partnership with ESA Education to be able to open up Astro Pi to young people across ESA Member states. The European Astro Pi Challenge has been going from strength to strength each year since, inspiring young people and adult mentors alike.

And today…

In 2021 we decided it was time to retire Izzy and Ed and replace them with upgraded Astro Pi computers with plenty of new and improved hardware, including a 扒开双腿吃奶呻吟做受视频 Pi 4 Model B with 8 GB RAM.

Dave Honess, STEM Didactics Expert at the European Space Agency, was engineering lead at the 扒开双腿疯狂进出爽爽爽 for the first Astro Pi Challenge, and the return of the original hardware is a special event and moment of reflection for him: “It was a strange 扒开双腿疯狂进出爽爽爽 to open the box and hold the original Astro Pis again after all that time and distance they have travelled — literally billions of miles. Even though their mission is over, we will continue to learn from them with a tear-down analysis to find out if they have been affected by their time in space. Since Principia, I have watched the European Astro Pi Challenge grow with pride year on year, but I still feel very fortunate to have been there at the beginning.”

Thanks to the upgraded hardware, we are able to continue to grow the Astro Pi Challenge in collaboration with ESA Education. And each year it’s so exciting to see the creative and ingenious programs tens of thousands of young people from across Europe send us; 24,850 young people took part in the Challenge in the 2022/2023 cycle.

But how have Astro Pis Izzy and Ed fared in space over these seven years? Jonathan Bell, Principal Software Engineer at 扒开双腿吃奶呻吟做受视频 Pi Limited, had a chance to find out first-hand: “I was lucky enough to have a look inside the returned Astro Pis. I was looking for the cosmetic effects of the unit being on the ISS for so long. On the inside they still look as pristine as when I assembled them! Barely a speck of dust on the internal boards, nor any signs that the external interface ports were worn from their years of use. A few dings and scrapes on the anodised exterior were all that I could see — and a missing joystick cap (as it turns out, hot-melt glue isn’t a permanent adhesive…). It was great to see that they still worked! It made me feel proud for what the team and the Astro Pi programme has achieved over the years. It’s good to have Izzy and Ed back!”

Back in 2015 we ran a competition where students could design and program computer science experiments, to be run by Tim Peake on specially cased 扒开双腿吃奶呻吟做受视频 Pis called Astro Pis. Here’s the original competition video, voiced by Tim himself:

https://vimeo.com/117274487

The competition ran from January to July 2015 and produced seven winning experiments, which were launched into space a few days before Tim started his mission. Between February and April 2016, these experiments were run on board the ISS under Tim Peake’s supervision. They’re mostly based around the sensors found on the Sense HAT, but a few also employ the 扒开双腿吃奶呻吟做受视频 Pi Camera Module. Head over to the Astro Pi website now to check out the results, released today!

You might also know that we ran an extension to this competition involving a couple of music-based challenges. These challenges have no scientific output to discuss, because they were part of a crew care package for Tim’s enjoyment, but you can get your hands on the winning code to turn the Astro Pis into MP3 players and Sonic Pi tunes.

One of the main things we’ve learnt from running Astro Pi is that the biggest motivational factor for young people is the very tangible goal of having their code run in space. This eclipses any physical prize we could offer. Many people see space as quite distant and abstract, but with Astro Pi you can actually get your hands on space-qualified hardware, create something that would work up in space, and become an active participant in the European space programme.

Many of the Astro Pi winners now express an interest in studying aerospace and computer science. They’ve gained exposure to the real-life process of scientific endeavour, and faced industrial software development challenges along the way. We hope that everyone who participated in Astro Pi has been positively influenced by the programme. The results also demonstrate that the payload works reliably in space. This has been noticed by ESA, who are now planning to use it during upcoming missions. It’s really important for us that the payload continues to be used to run your code in space, so we’re working hard with ESA to make sure that we can do Astro Pi all over again.

This project has been a huge collaborative effort from the start and the 扒开乡村美妇两腿挺进 would like to thank everyone who has participated in the competitions, and the following companies who have contributed staff time, facilities, and funding to make it all happen: UK Space Agency, European Space Agency, BIOTESC, TLOGOS, Surrey Satellite Technology, Airbus Defence and Space, CGI Group, QinetiQ Space, UK Space Trade Association, ESERO UK, KTN Space, and Nesta. Of course, Tim Peake himself has been hugely supportive and enthusiastic about the project from the start.

We would also like to thank Libby Jackson, who is the Astronaut Flight Education Programme Manager at the UK Space Agency and a former flight director at ESA. She oversees all of the Principia educational activities, including Astro Pi.

During the interview for her job at the UK Space Agency a few years ago, she pitched an idea for running a project on the ISS involving 扒开双腿吃奶呻吟做受视频 Pi computers. Instead of launching traditional physical equipment, the experiments would be in the form of computer software, meaning that many more experiments could be accommodated. That kernel of an idea is what eventually became Astro Pi.

During his time in space, Tim has been using Ed and Izzy to run apps, carry out science experiments and play music designed and coded by UK school students, and he’s taken some great photos of them on the station:

Both computers have also spent some weeks in a flight recorder mode, saving sensor readings to a database every ten seconds, and we’ve made these space data available for everyone to download and analyse. Take a look at our Flight Data Analysis resource to explore what they recorded as they orbited our planet.

Ed and Izzy will say goodbye to Tim when he returns from space this Saturday; you’ll be able to watch him land. Our Astro Pi units will stay on board the ISS until 2022, and we hope we’ll soon be able to share exciting news about what they’ll be doing next. Stay tuned!

Our intrepid Astro Pi units Izzy and Ed launched in December and were deployed by British ESA astronaut Tim Peake in February. We’ve seen the first part of their animated adventures; now we bring you the second part of their story, featuring some very special guests.

We’re especially excited that our Astro Pis have met Robonaut, NASA’s humanoid robot, as well as human crew members from ESA, NASA and Roscosmos.

After Ed and Izzy finished running apps and experiments coded by UK school students, they entered a flight recorder mode where they saved sensor readings to a database every ten seconds. They each recorded their orientation and acceleration, as well as temperature, humidity and pressure, over a period of about two weeks. We’ve now made the data they recorded on the ISS available for everyone to download, so you can analyse it any way you like, and we’ve also prepared a Flight Data Analysis resource to help you interpret and handle the data. We’re really looking forward to seeing how you use these data to analyse and interpret the movement of the space station and the environment on board.

Both Astro Pi units have been tweeting about some of their activities, including some great Earth observation images from Izzy, and they’re also talking about opportunities to get involved with their mission. Follow Ed and Izzy on Twitter to see what they’re up to!

Ed and Izzy

On Monday this week we released the first of four short cartoons that tell the story of the Astro Pi mission. Part 1 introduces Ed and Izzy, the two Astro Pi flight units that are up in space right now.

You may recognise the voice-over: it’s TV science presenter Fran Scott from Absolute Genius and How to be Epic. Thanks Fran!

The idea to anthropomorphise the Astro Pis came from Tim Peake himself. He was a fan of what ESA had done previously with Rosetta and Philae’s social media accounts, and felt that this would be a great way to involve young people in the mission.

Ed @astro_pi_vis and Izzy @astro_pi_ir have their own Twitter accounts and will be tweeting about what they’re doing over the coming weeks. They’re named after the real-life friendship between Sir Isaac Newton (Izzy) and Edmond Halley (Ed) which resulted in the publication of the famous 17th-century physics book, Principia Mathematica, after which Tim’s mission is named.

Deployment

On the 4th of January Tim unpacked Ed and took this amazing picture in the Columbus module of the ISS. You can download the original from Tim’s Flickr account.

Look what turned up today…nearly time to start running your code in space! @astro_pi @扒开双腿吃奶呻吟做受视频_Pi pic.twitter.com/Dmdjev2BPh

The Astro Pis were originally scheduled to be powered up on the 11th of January; however, it was postponed due to the spacewalks they recently undertook, which rightly take priority over anything educational.

It gives us great pleasure to announce that yesterday Ed was successfully deployed by Tim. He’s powered up and is now running the student experiments that won the 2015 Astro Pi competition.

It takes several days to get images back from the ISS because they have to be screened by ESA and NASA for crew privacy reasons. So keep an eye on Tim’s social media accounts over the next few days for pictures of Ed online and working!

Ed is running most of the experiments, but the others will be run by Izzy who will be deployed in the Harmony node of the ISS on February 15th. Izzy needs to look through a hatch window, as she’ll be taking infrared pictures of the Earth – there are no windows in Columbus.

If you enjoy watching the ISS Live Stream you may be able to spot them from time to time!

Flight Data Analysis

Once Ed and Izzy have finished running their student experiments, they will each begin a long-term ISS environmental monitoring experiment that you can all take part in.

They’ll enter a flight recorder mode where they save sensor readings to their own databases every ten seconds. Because the sensor readings are taken so often, there will be masses of data to search through, so we need your help to look through the data and find out what was going on. There could be strange, unexplained things, or just the normal day-to-day activities of the astronauts.

Check out the resource for this below. The data will not be available for several weeks yet, but there is some sample data here for you to practice with.

New Coding Challenge

It also gives us great pleasure to announce two new coding challenges, where the prize is to have your code uploaded and run by Ed or Izzy in space!

That’s right – your code in space!

The first requires you to write Python Sense HAT code to turn Ed and Izzy into an MP3 player, so that Tim can plug in his headphones and listen to music. The second requires you to code Sonic Pi music for Tim to listen to via the MP3 player. You may enter both challenges if you wish.
