NASA begins 49‑hour Artemis II wet dress rehearsal, fuels SLS ahead of simulated Feb. 2 liftoff
NASA began a 49‑hour wet dress rehearsal at Kennedy Space Center on Jan. 31 for Artemis II, powering up and fueling the SLS core in a full practice countdown. The test—including a simulated liftoff targeted for 9 p.m. ET Feb. 2—is the final major check before a four‑astronaut lunar flyby.
