Artemis II Commander Recounts 219,669-Nautical-Mile Overshoot, Fearing Crew Would Not Return

3 articles · Updated · Livescience.com · Oct 22

Summary

  • 219,669 nautical miles from Earth, Artemis II commander Reid Wiseman said he felt “real fear” when Orion’s distance kept rising past the planned turn-back point before finally dropping.
  • Three minutes after mission control’s stated maximum of 219,667 nautical miles, the odometer still climbed, leading Wiseman to think the spacecraft had gone too far on the moon flyby.
  • The scare went unnoticed inside the cabin: Victor Glover and Christina Koch were observing the moon, while Jeremy Hansen was reporting to mission control, until Wiseman saw 219,668 and told them, “We’re going home.”
  • Wiseman credited NASA’s flight controllers and engineers for the safe return from the nearly 10-day mission, launched April 1 as the first crewed Orion flight and the first human lunar mission since Apollo 17 in 1972.
