A full moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher at Launch Pad 39B at NASA’s Kennedy Space Center in Florida in the early hours of February 1, 2026.
The agency concluded a wet dress rehearsal for the agency’s Artemis II test flight early Tuesday morning, successfully loading cryogenic propellant into the SLS (Space Launch System) tanks, sending a team out to the launch pad to closeout Orion, and safely draining the rocket. The wet dress rehearsal was a prelaunch test to fuel the rocket, designed to identify any issues and resolve them before attempting a launch. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.

2026年2月1日凌晨，位于佛罗里达州NASA肯尼迪航天中心的39B发射台上，一轮满月映照着矗立在移动发射架上的SLS（太空发射系统）火箭与猎户座飞船。
周二清晨，NASA完成了阿尔忒弥斯2号试飞任务的湿彩排（低温推进剂加注演练）。在此过程中，团队成功将低温推进剂注入SLS火箭贮箱，派遣团队前往发射台完成猎户座飞船的封舱作业，并随后安全排空了火箭燃料。湿彩排是一项包含燃料加注流程的发射前测试，旨在正式发射前识别并解决潜在问题。为预留时间供团队评估数据并进行第二次湿彩排，NASA目前将该试飞任务的最早发射窗口调整至3月。
