NASA begins Artemis II wet dress rehearsal, fueling the SLS and Orion ahead of a possible Feb. 8 launch window.
NASA conducted a test of its newly redesigned RS-25 engine for future flights of the Space Launch System (SLS) rocket.
On Monday, after rolling the SLS rocket to be used for the Artemis II mission to the pad in January, NASA attempted its first wet-dress test with this new vehicle. At one of the main interfaces where liquid hydrogen enters the vehicle, a leak developed, not dissimilar to problems that occurred with the Artemis I rocket three years ago.
