Four astronauts are preparing to come home — and the final leg of their journey is among the most physically demanding moments any human being can experience. The crew of NASA’s Artemis II mission is set to re-enter Earth’s atmosphere at speeds approaching 23,839 mph before splashing down off the Southern California coast near San Diego on Friday evening, bringing a historic 10-day lunar mission to a close.
The Orion capsule, which launched from Florida last week, carried the crew on a trajectory past the far side of the moon — a region of space no human had ever reached before. In doing so, the 4 crew members became the farthest-flying humans in the history of spaceflight, surpassing the distance record previously held by the Apollo 13 crew at approximately 252,000 miles from Earth.
4 astronauts, 1 defining moment
The crew making the return journey consists of 1. NASA mission commander Reid Wiseman, 2. NASA mission pilot Victor Glover, 3. NASA astronaut Christina Koch and 4. Canadian Space Agency astronaut Jeremy Hansen. Together they represent the first crewed mission under NASA’s Artemis program, which is working toward returning humans to the lunar surface by 2028 and establishing the foundation for future missions to Mars.
As re-entry approaches, the Orion capsule’s heat shield will face an extreme test. The friction generated by the spacecraft’s collision with the upper atmosphere at those speeds produces conditions comparable to a fireball — a moment that has been on the minds of the crew since well before launch. Glover, for his part, has been mentally preparing for re-entry since the day the crew was assigned to the mission back in April 2023. He has spoken about the emotional weight of the experience, noting that the crew has accumulated far more stories and images than they have yet had time to absorb, and that the re-entry itself — as intense as it is — represents one final profound chapter of everything they have been through.
A lunar flyby and a deeply personal moment
During the mission, the crew conducted a six-hour flyby of the moon, observing its surface from approximately 4,000 miles above and providing scientists on the ground with real-time human observations that automated systems simply cannot replicate. The perspective from that altitude, looking out at the moon’s shadowed far side from a crewed spacecraft, marked a milestone not seen since the Apollo era.
One moment during the flyby carried a deeply personal dimension for Wiseman. As the Orion capsule approached the moon, Hansen suggested naming a newly observed lunar crater after Wiseman’s late wife, Carroll, who passed away from cancer in 2020. Wiseman accepted the gesture with visible emotion, acknowledging that while he embraced it wholeheartedly, he was unable to find the words to fully speak to what it meant in that moment.
The crew also had brief windows during the mission to connect with their families back on Earth — exchanges that Wiseman described as profoundly meaningful, with crew members moved to laughter and tears in equal measure while reaching out to the people they love from a quarter of a million miles away.
What comes next for Artemis
Koch has spoken about the mission in the context of a larger relay effort among astronauts, with each crew building on what the last one learned and preparing the path for those who follow. The next phase, Artemis III, will focus on docking procedures in low-Earth orbit involving Orion and the lunar landers being developed for future moon landings. Artemis IV, targeted for 2028, is expected to deliver the program’s first crewed lunar landing since Apollo 17 in 1972.
Scientists at NASA‘s Mission Control in Houston have been monitoring the mission continuously, and the crew is expected to splash down at approximately 8 p.m. ET on Friday.
