Artemis is a complex series of missions designed to enable human exploration of Moon and Mars.
Artemis I is the first mission, also called Artemis I Moon Mission.
"NASA will hold a media teleconference at 12 p.m. EDT on Friday, May 27, to discuss the status of the next wet dress rehearsal test of the agency’s Space Launch System (SLS) rocket and Orion spacecraft at the agency’s Kennedy Space Center in Florida ahead of the uncrewed Artemis I lunar mission.
"The rehearsal is the final test needed before launch and calls for NASA to test the system including operations to load propellant into the rocket’s tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain the tanks to give them an opportunity to practice the timelines and procedures they will use for launch" as NASA reports.
