The four crew members of NASA's Artemis II moon mission returned to Earth Friday evening, splashing down in the Pacific Ocean at 8:07 p.m. ET. NASA extracted the astronauts from the Orion spacecraft and flew them via helicopter to a U.S. Navy ship, completing a record-breaking 10-day mission that took them around the moon.
The Artemis II mission began with the successful liftoff of NASA's SLS (Space Launch System) rocket on April 1 at 6:35 p.m. During the mission, the astronauts completed a historic lunar flyby, marking humanity's return to the vicinity of the Moon for the first time in more than 50 years.
The final mission numbers from NASA's Flight Dynamics team are extraordinary: the crew flew 700,237 miles, reached a peak velocity of 24,664 miles per hour, hit their flight path angle target within 0.4%, flew an entry range of 1,957 miles, and landed within less than a mile of their target.
The crew consisted of NASA astronauts Reid Wiseman (commander), Victor Glover (pilot), Christina Koch (mission specialist), and CSA (Canadian Space Agency) astronaut Jeremy Hansen (mission specialist).
The spacecraft, named Integrity by its crew, became a symbol of both technical achievement and human resolve.
Returning from the moon, the Orion capsule slammed into the atmosphere, compressing air that heated up to about 2,700 degrees Celsius, hotter than lava. To survive this, Orion used a specially designed ablative heat shield made from a material called Avcoat, which slowly burns and erodes away, carrying heat with it and protecting the astronauts inside.
After Orion dropped into the Pacific Ocean, Mission Control called it "a perfect bullseye splashdown." Commander Reid Wiseman radioed that all four crew members were doing well.
Before the crew was seen after splashdown, NASA's landing and recovery director reported they were already out of their seats having a good time with the medical team inside the capsule, taking selfies.
During the 10-day Artemis II mission, the crew became the first humans to travel toward the moon in more than 50 years and set a new record for the farthest distance ever traveled from Earth. Re-entry was particularly notable because Orion's heat shield had known design flaws, yet in the end, the astronauts emerged from the capsule safe and in high spirits.
NASA Associate Administrator Amit Kshatriya highlighted the extraordinarily narrow margin of error: "Yesterday, flight director Jeff Radigan said we had less than a degree of an angle to hit after a quarter of a million miles to the moon and their team hit it. That is not luck; that is 1,000 people doing their job."
NASA Administrator Jared Isaacman declared the mission a milestone in humanity's return to the moon: "We are back in the business of sending astronauts to the Moon." He emphasized that this is not meant to be a once-in-a-lifetime moment "This is just the beginning."
NASA aims to land astronauts on the lunar surface in 2028, with Artemis III, setting the stage for building a permanent base on the Moon.
