English: NASA’s Space Launch System (SLS) rocket, with the Orion capsule atop, slowly rolls out of the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida on March 17, 2022, on its journey to Launch Complex 39B. Carried atop the crawler-transporter 2, NASA’s Moon rocket is venturing out to the launch pad for a wet dress rehearsal ahead of the uncrewed Artemis I launch. The first in an increasingly complex set of missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and the first person of color on the lunar surface, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
