Summary
The astronauts of NASA's Artemis II mission described their intense experience returning to Earth after a 10-day trip around the moon. They explained how the spacecraft heated to 5,000 degrees Fahrenheit and experienced a six-minute communication blackout caused by Earth's atmosphere during reentry.
Key Facts
- The Artemis II crew included commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian astronaut Jeremy Hansen.
- Reentry into Earth's atmosphere is much more intense than rocket launch, creating extreme heat and a plasma bubble around the spacecraft.
- The heat reached up to 5,000 degrees Fahrenheit during reentry.
- The plasma bubble blocked radio signals for about six minutes, causing a communications blackout with Mission Control.
- The astronauts experienced a strong "rumbling" sensation that cannot be replicated on Earth before landing.
- Commander Wiseman reassured the crew by saying "Everything's nominal," meaning everything was working normally.
- Pilot Victor Glover maintained precise control of the spacecraft under four times Earth's gravity for 13 minutes, which was key to a safe reentry and splashdown.
- The splashdown in the ocean was described as textbook, meaning it went exactly as planned.
