黎明时分的太空发射系统火箭

NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen at sunrise atop a mobile launcher at Launch Complex 39B, Monday, April 4, 2022.

From April 1-4, the Artemis I launch team is conducting the wet dress rehearsal test at NASA’s Kennedy Space Center in Florida. Ahead of the Artemis I flight test, the wet dress rehearsal will run the launch team through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch.
