A space-science learning adventure for children aged 7-11

An interactive, space science adventure for children aged 7-11 to inspire them in STEM subjects. Designed and delivered by the award-winning Unlimited Space Agency in collaboration with some of the UK’s most brilliant space science organisations. As Cadets, children will complete a series of Missions through the Astro Science Challenge app to become fully fledged Agents of UNSA.

If you’ve only just heard about The Astro Science Challenge: LIVE! which ran between April – June 2020 and you’re worried you missed out on the fun, don’t! The app is still available to download using the buttons above, the Mission resources can be found on our Team Leader Resources page, all the broadcasts (including our interviews with astronauts Samantha Cristoforetti and Suni Williams) are still live on our YouTube channel and you can read all of the emails with news and top tips that we sent to our Team Leaders during the adventure here

The patron of UNSA is the British and European Space Agency astronaut Tim Peake who lived and worked as a scientist on board the International Space Station for 6 months – the first British person to do that. Tim is passionate about getting kids into science and is supporting this project.

“The Unlimited Space Agency is great. Their approach to inspiring children about science is rigorous, fun and it works! I’m proud to serve with them on their mission to inspire the next generation of scientists and space explorers.” Tim Peake
