NASA's Artemis II mission reaches its climactic moment today as the Orion spacecraft carrying four astronauts prepares for its return from the Moon. The crew—Reid Wiseman, Christina Koch, Victor Glover, and Jeremy Hansen—is scheduled to splash down off the San Diego coast at approximately 8:07 PM ET. The agency will broadcast the historic landing live across multiple platforms, including YouTube, NASA+, Netflix, and HBO Max, with coverage beginning at 6:30 PM ET.
Artemis II crew prepares for splashdown today
Following a nine-day journey through space aboard NASA's powerful SLS rocket, the Artemis II mission now faces what many consider its most critical phase. The Orion spacecraft will endure approximately 13 minutes of atmospheric re-entry, exposing it to extreme temperatures reaching 5,000 degrees Fahrenheit. This particular challenge carries additional significance given lessons learned from the Artemis 1 mission, which experienced unexpected complications during re-entry.
Critical re-entry phase tests spacecraft durability
During the uncrewed Artemis 1 flight, the Orion vessel executed a "skip reentry" maneuver, briefly using aerodynamic lift to hop back into space before descending again. This phenomenon resulted in excessive heat damage to the spacecraft's exterior. Following extensive investigation, NASA engineers determined the craft remained flight-worthy but adjusted procedures for the crewed mission. The Artemis II descent will employ a more gradual approach to Earth, deliberately reducing the vehicle's exposure to extreme thermal stress.
Lessons from Artemis I improve procedures
This mission holds particular historical weight: it marks the first time in 53 years that NASA will bring human astronauts back from lunar orbit. The crew will have completed a remarkable 695,081-mile journey, capturing unprecedented imagery and demonstrating the ongoing capabilities of international space collaboration.
Historic return after 53-year lunar gap
As the world watches this pivotal moment unfold, the successful completion of Artemis II will represent a major milestone in humanity's renewed commitment to lunar exploration and deep-space missions.
