NASA Artemis Program

After completing a flight readiness review in which all teams were polled "go," NASA narrowed Artemis II's launch target to a primary window on April 1 at 6:24 p.m. ET with a backup opportunity April 2 at 7:22 p.m. ET for the 10‑day crewed lunar flyby. Ground teams repaired a helium‑system seal discovered after a February fueling test and plan to roll the Space Launch System and Orion back to Launch Pad 39B around March 19 with no additional wet dress rehearsal; the crew will enter quarantine March 18 and travel to Kennedy Space Center on March 27, though officials say remaining work in the Vehicle Assembly Building and at the pad continues.
