The Reality of Space Junk and Why It Matters

~60 min · 15 stations

The Reality of Space Junk and Why It Matters 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 common sources of man-made objects orbiting Earth; summarize major milestones in human space exploration history; explain how scientists monitor objects currently circling Earth.

Conductor

The Conductor

Welcome aboard this orbital transit. We are navigating the crowded lanes of Earth's orbit to study the debris left by decades of flight. Watch your step as we clear the path ahead.
