Artemis II could be NASA's make-or-break moon shot

NASA is preparing Artemis II to launch with four astronauts aboard Orion after years of delays and billions in development costs.

The 322-foot Space Launch System rocket and Orion capsule are at Kennedy Space Center as NASA finalizes preparations for Artemis II. Fueling tests are complete and four astronauts are in quarantine. The mission would be the first crewed launch toward the moon in more than 50 years and a key test for the Artemis program. The program has experienced long delays and rising costs over many years. Key details: - Artemis II could launch as early as Wednesday with four astronauts aboard the Orion spacecraft. - The Space Launch System rocket and Orion spacecraft have cost reported sums in the tens of billions of dollars to develop. - An inspection after Artemis I found damage to part of Orion's heat shield; for Artemis II NASA plans a steeper re-entry profile to reduce time in peak heating. - The SLS design traces to post-shuttle policy choices that reused shuttle-era components, a factor cited for delays and higher costs. - NASA has announced a revised Artemis cadence, moving Artemis III to a low-Earth orbit test in 2027 and aiming for a lunar landing campaign in the following years. Summary: A successful Artemis II flight would give NASA an operational test of crewed SLS/Orion systems and could affect momentum for the broader Artemis timeline. How the mission proceeds will shape the agency's stated plans for more frequent launches and future lunar operations.
