WASHINGTON D.C.: NASA has conducted a confidence test on its Artemis II spacecraft ahead of the first crewed mission of the Artemis program, which will carry astronauts around the Moon and back.
In a post on X, the space agency stated that following the Feb. 12 test, teams are reviewing data and assessing findings before scheduling the next test, a second wet dress rehearsal, later this month. The earliest possible launch window remains in March.
According to NASA, the test involved partially filling the Space Launch System (SLS) core stage liquid hydrogen tank to evaluate newly replaced seals in a propellant fill area. During the test, ground support equipment experienced an issue that reduced hydrogen flow into the rocket. Despite this, engineers achieved confidence in several key objectives and gathered critical data at the core stage interfaces, the same area that had experienced a leak during the previous wet dress rehearsal.
“Engineers will purge the line over the weekend, inspect the equipment, and replace a filter suspected to have caused the reduced flow,” NASA said. Findings from this review will guide the timeline for the next wet dress rehearsal.
Artemis II marks a significant step in NASA’s plan to return humans to the Moon. Unlike the uncrewed Artemis I, this mission will carry four astronauts onboard the Orion spacecraft to test life-support systems and deep-space operations. The mission will also lay the groundwork for Artemis III, which aims to land astronauts on the lunar surface and enable long-term lunar exploration.
