Artemis II Crew Prepares for Moon Mission Splashdown

The crew of NASA’s Artemis II mission is facing the most physically demanding and high-risk phase of their journey as they prepare for re-entry into Earth’s atmosphere on April 10, 2026. The return involves a fiery 13-minute descent that subjects the astronauts and their spacecraft to extreme thermal and mechanical stresses.

The Orion spacecraft is expected to plunge through the atmosphere at approximately 24,000 mph (38,600 kph). During this process, the capsule will encounter temperatures reaching up to 5,000 degrees Fahrenheit (2,760 degrees Celsius), relying entirely on a heat shield for protection and parachutes to decelerate before landing.

Managing Re-entry Risks and Heat Shield Integrity

A primary scientific concern for this mission involves the integrity of the Orion heat shield. The critical protective layer sustained unexpected damage during the uncrewed Artemis I test flight in 2022, revealing known design flaws that NASA engineers have had to mitigate for the crewed flight.

To reduce the risk to the crew, NASA implemented a modified re-entry path. The spacecraft is designed to descend at a steeper angle and at a faster speed, a strategy intended to minimize the total duration of time the capsule is exposed to the highest levels of atmospheric heat.

The success of the mission depends on the synchronized performance of several critical systems during these final minutes. NASA Associate Administrator Amit Kshatriya noted on April 9, 2026, that the mission’s outcome relies on the functioning of life support, navigation, propulsion, communications and the recovery systems.

Crew and Mission Milestones

The four astronauts on board—NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen—have set a new record for the farthest distance humans have ever traveled from Earth.

This mission marks the first time in over 53 years that humans have returned to Earth from the moon. The crew spent 10 days on the mission, during which they performed a historic lunar flyby.

Recovery and Splashdown Timeline

The targeted splashdown is scheduled for 8:07 p.m. EDT (5:07 p.m. PDT) on April 10, 2026, in the Pacific Ocean off the coast of San Diego. NASA has confirmed that weather conditions at the splashdown site are favorable for the recovery operation.

Following the landing, the recovery process will involve the following steps:

• NASA recovery teams will extract the four astronauts from the Orion capsule one by one.
• The crew will be transported via helicopter to a waiting U.S. Navy ship.
• A combined NASA and U.S. Military recovery team will manage the immediate post-landing safety and health assessments.

Before the final descent, the crew performed their third return trajectory correction burn at 2:53 p.m. On April 10, 2026, to refine the spacecraft’s path for atmospheric entry. As the capsule descends, the crew will experience a period of radio blackout during the peak of re-entry.
