Mission: Starlight - a global experiment on UV protection


Your mission is to protect astronauts from the effects of harmful UV light. Experiment with different materials to discover which blocks UV light the best. Tell us about your results to receive a mission completion certificate and patches, and to unlock a secret video featuring Tim Peake.

This experiment is now closed and data cannot be posted to the website.
You can however run a class investigation from the available worksheet.

Instructions for taking part are also available in Welsh.
