Summary

NASA has successfully completed a wet dress rehearsal for the Artemis 2 mission, marking a significant milestone toward returning astronauts to lunar orbit. The test brings the agency closer to launching its first crewed mission to the Moon since Apollo 17 in 1972.

Key Facts

• Wet dress rehearsal for Artemis 2 has been successfully completed
• The mission will be the first crewed lunar flight since 1972
• Four astronauts will orbit the Moon without landing during the approximately 10-day mission

Context

The wet dress rehearsal involves loading the Space Launch System rocket with propellant and running through the countdown sequence, stopping just before engine ignition. This critical test validates that ground systems, the rocket, and the Orion spacecraft can work together as intended.

Artemis 2 will send four astronauts on a roughly 10-day journey around the Moon without landing, serving as a precursor to Artemis 3, which aims to return humans to the lunar surface. The successful completion of this rehearsal suggests the mission could launch within weeks, though NASA has not announced a specific date.

The Artemis program represents NASA's long-term plan to establish a sustainable human presence at the Moon while developing technologies and experience needed for future Mars missions.
