Why does Artemis II practice building a radiation shelter onboard?
Show answer & explanation
Answer: Deep-space crews need a plan for solar storms
Deep-space crews need a plan for solar storms ✓ — Correct! Outside Earth’s stronger protection, deep-space crews face more radiation risk. Artemis II tests how astronauts could use onboard supplies to create better temporary shielding.
Orion already blocks all radiation — Wrong. Orion offers some protection, but not total protection from every high-radiation event.
Radiation matters only at launch and landing — Wrong. Radiation is a concern throughout deep-space flight, not just during launch or reentry.
