OBJECTIVE

Describe the cause, change or relationship that explains space debris, planetary protection, and a sustainable future.

HEAR & UNDERSTAND

Sustainable exploration reduces debris, prevents harmful contamination and protects future science and access to space. Missions plan safe disposal, avoid unnecessary biological transfer and use resources responsibly. What do you predict will happen next?

PARTICIPATE

Build a paper mission card with a destination, science question, instrument, safety rule, power source and way to send results home. Connect what you notice to space debris, planetary protection, and a sustainable future using space debris and planetary protection. Make a prediction before trying it.

SUCCESS LOOKS LIKE

Explain the idea in your own words using space debris and planetary protection.

The big idea

Sustainable exploration reduces debris, prevents harmful contamination and protects future science and access to space.

Missions plan safe disposal, avoid unnecessary biological transfer and use resources responsibly.

HOW SCIENTISTS KNOW

Debris tracking, collision analysis and planetary-protection procedures measure and reduce risk.

WORDS TO OWN

A COMMON WRONG MODEL

Space is too large for litter to matter.

REBUILD IT WITH EVIDENCE

Useful orbital regions are limited; fast debris can damage spacecraft and create more fragments.

A scientifically true sentence can still create a false picture. This repair makes the relationship visible.

Check understanding

Which statement best explains space debris, planetary protection, and a sustainable future?

Choose the explanation that matches the evidence—not just the most familiar words.

Three things to remember

✓Sustainable exploration reduces debris, prevents harmful contamination and protects future science and access to space.
✓Missions plan safe disposal, avoid unnecessary biological transfer and use resources responsibly.
✓Evidence matters: debris tracking, collision analysis and planetary-protection procedures measure and reduce risk.
