Nexus Island – ESA Extension

Discover the new expansion for the game “Nexus Island”. Developed by the European Space Agency, this expansion adds a new scenario and new cards to incorporate the “space observation” element into the game. This expansion is available to download as a supplement to the original “Nexus Island” game.

Coming back to earth safely

In this activity, students will learn about the concept of controlled and uncontrolled satellite return and try to find a way to reduce space debris by modifying satellites so that they return to Earth.

Cleaning up space!

In this activity, students will explore ways to remove space debris and design a debris-capture tool by studying deployable “tentacles.” Finally, students will compare the effectiveness of various adhesive materials.
