任务简介
Artemis II 是 Artemis 计划中的首次载人任务。Artemis II 将把 4 名宇航员——3 名美国人和 1 名加拿大人——送往月球并返回地球。 该任务将测试 NASA 的 Orion 飞船的核心系统，包括关键的生命支持系统，以及其他在 Artemis I 中因无船员而无法测试的系统。
原文
Artemis II is the first crewed mission as part of the Artemis program. Artemis II will send a crew of 4 - 3 Americans and 1 Canadian around the moon and return them back to Earth. The mission will test the core systems of NASA's Orion spacecraft including the critical life support system, among other systems which could not be tested during Artemis I due to the lack of crew onboard.
