"NASA is gearing up to launch Artemis II, the agency's highly anticipated first crewed mission to moon in more than half a century. A crucial step is Artemis II's wet dress rehearsala major test of the Space Launch System (SLS) rocket and the Orion capsule that will house the mission's four astronauts. At Florida's Kennedy Space Center, engineers will attempt to fuel the rocket and simulate a countdown to launch as soon as January 31, the agency said in an update on Monday."
"The wet dress rehearsal will see NASA technicians load up the uncrewed spacecraft's rocket with more than 700,000 gallons of cryogenic fuelspecifically, liquid oxygen and liquid hydrogenbefore running through a countdown to launch.

NASA is preparing Artemis II, the first crewed lunar mission in more than fifty years, to send four astronauts around the moon and back. A critical wet dress rehearsal will load the Space Launch System rocket and Orion capsule with over 700,000 gallons of cryogenic propellants—liquid oxygen and liquid hydrogen—and simulate a full countdown at Kennedy Space Center as soon as January 31. If the rehearsal completes successfully, a crewed launch could proceed as early as the first week of February. Previous testing on Artemis I revealed recurring liquid-hydrogen leaks that caused significant delays, and similar issues could force rollback for further troubleshooting.
