From left to right, CSA (Canadian Space Agency) astronaut Jeremy Hansen and NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman stand outside before boarding their Orion spacecraft inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida as part of the Artemis II countdown demonstration test, Saturday, Dec. 20, 2025. Because the SLS (Space Launch System) rocket upon which they will launch is not yet at the launch pad, the crew boarded Orion inside NASA Kennedy’s Vehicle Assembly Building, where engineers are conducting final preparations on the spacecraft, rocket, and ground systems. During the rehearsal, teams went through all the steps that will be taken on launch day, winding the clock down to just a few seconds before liftoff.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars, for the benefit of all.

从左至右，加拿大航天局宇航员杰里米·汉森（Jeremy Hansen）以及NASA宇航员克里斯蒂娜·科赫（Christina Koch）、维克托·格洛弗（Victor Glover）和里德·怀斯曼（Reid Wiseman）在佛罗里达州肯尼迪航天中心车辆组装大楼内登上猎户座飞船前，在建筑外合影。这是2025年12月20日星期六进行的阿尔忒弥斯二号任务倒计时演练测试的一部分。由于用于发射的太空发射系统火箭尚未转运至发射台，机组成员在肯尼迪航天中心的总装大楼内登船，此时工程师正在对飞船、火箭以及地面系统进行最后准备。演练过程中，各团队完整走查了发射当天将执行的全部流程，将倒计时推进至起飞前仅剩数秒。
通过阿尔忒弥斯计划，NASA将把宇航员送往月球开展科学探索并创造经济效益，同时为人类首次载人火星任务奠定基础，惠及全人类。
