Questions & Answers

Q: What is the purpose of the distant retrograde orbit departure burn?

The burn is essential for leaving the orbit around the Moon and preparing for a return to Earth. It marks a milestone in the Artemis 1 mission.

Q: How does being further from Earth affect astronauts on future Artemis missions?

Being further from Earth means astronauts have limited protection from radiation, especially solar particle events. Monitoring the solar environment and implementing protective measures become crucial.

Q: How do astronauts protect themselves from radiation during a solar particle event?

Astronauts can take shelter in a designated area within the spacecraft, using existing stowage bags and equipment to shield themselves from lower energy particles.

Q: What measures are being taken to mitigate the health impacts of space radiation on astronauts?

The Space Radiation Element team is researching strategies to understand and mitigate the health impacts of space radiation. This includes health monitoring, early disease screening, and potentially developing compounds to protect the body from biological damage.

Summary & Key Takeaways

  • The Artemis 1 mission performed the distant retrograde orbit departure burn, which is necessary to leave the elliptical orbit around the Moon.

  • The spacecraft reached a record distance from Earth, surpassing the previous record set by Apollo 13 during its mission.

  • Future missions will face challenges due to the space radiation environment and will require protective measures to ensure astronaut safety.
