Space Junk Cleanup

~60 min · 15 stations

Space Junk Cleanup is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary sources of man-made space debris; explain the typical operational life of modern satellites; describe the relationship between altitude plus orbital speed.

Conductor

The Conductor

All aboard for a trip through the orbital graveyard. We are clearing a path through the debris to keep our future in the stars wide open.
