内容总结：

美国东部时间4月10日晚8时07分，执行“阿尔忒弥斯2号”载人绕月飞行任务的“猎户座”飞船在加利福尼亚州圣迭戈附近海域成功溅落，标志着此次为期10天的历史性绕月飞行任务圆满结束。此次任务是为未来载人登月计划进行的关键试飞。

飞船返回过程按计划完成多项关键动作：服务舱于晚7时33分分离并在大气层烧毁；乘员舱于晚7时53分进入大气层，经历6分钟通讯中断后，在2.34万英尺（约7130米）和5400英尺（约1646米）高度先后展开减速伞与主降落伞，最终以每秒约61米的速度平稳溅落。

回收团队随后乘充气艇抵达飞船，协助四名宇航员出舱。晚9时34分，全部宇航员由直升机转移至“约翰·P·默瑟”号两栖舰接受健康评估。此次任务机组由美国宇航员威斯曼、格洛弗、科赫及加拿大宇航员汉森组成，于4月1日启航，在为期近10天的任务中抵达了载人航天史上最远的深空距离，并首次由宇航员亲自用手机拍摄了月球背面特写影像。

NASA在溅落后的发布会上透露，“阿尔忒弥斯3号”载人登月任务机组名单即将公布。该任务将验证SpaceX和蓝色起源开发的商业着陆器与“猎户座”飞船在近地轨道对接的能力，为实现人类重返月球表面奠定基础。

阿尔忒弥斯二号宇航员完成为期十天的绕月之旅顺利返回
宇航员按计划乘坐猎户座飞船在海上溅落。

搭载阿尔忒弥斯二号宇航员的猎户座飞船于东部时间4月10日晚8时07分在圣迭戈海岸附近成功溅落，标志着这次为期十天的绕月测试任务圆满结束。此次任务旨在为未来人类重返月球表面的计划进行关键技术验证。当晚7时33分，载有宇航员的返回舱与服务舱分离。服务舱按设计将在地球大气层中焚毁，而返回舱则承担着护送宇航员平安回家的使命。

晚7时53分，返回舱进入地球高层大气。由于飞船在制导下降过程中与大气摩擦产生高温等离子体，通信信号中断持续六分钟。飞船配备11具降落伞，当高度降至23400英尺（约7130米）时，先导稳定伞展开以调整姿态并减速。降至距地面5400英尺（约1645米）高度时，稳定伞脱离，三具主降落伞随即展开，将飞船下降速度降至每秒200英尺（约61米/秒），最终实现平稳溅落。

在回收团队乘充气艇抵达前，NASA工程师对溅落后的飞船进行了一系列检测。晚9时34分，四名宇航员全部出舱，由直升机转运至停泊在附近的约翰·P·默瑟号两栖舰接受健康评估。

阿尔忒弥斯二号任务于4月1日发射升空，搭载NASA宇航员里德·怀斯曼、维克多·格洛弗、克里斯蒂娜·科赫及加拿大航天局宇航员杰里米·汉森。在近十天的任务中，他们抵达了载人航天史上前所未有的深空区域，不仅拍摄了地球永远无法观测到的月球背面影像，更通过智能手机记录了月球表面的震撼特写，成为人类历史上首批亲眼直观月球背面景象的探索者。

在溅落后的新闻发布会上，NASA宣布将很快公布阿尔忒弥斯三号任务的乘组名单。该任务计划与SpaceX和蓝色起源公司正在研发的一至两艘商业着陆器在近地轨道对接，这些着陆器将承担运送人类登陆月球表面的重任。在正式实施载人登月前，NASA将通过此次任务验证着陆器与猎户座飞船的对接能力。

欢迎回家，里德、维克多、克里斯蒂娜和杰里米！🫶

The Artemis II astronauts are back after a 10-day journey around the moon
The astronauts splashed down aboard their Orion capsule as planned.
The Orion capsule carrying the Artemis II astronauts has successfully splashed down off the coast of San Diego at 8:07PM Eastern time on April 10. It signals the conclusion of Artemis II’s 10-day journey around the moon, which is meant to be a test flight for a future mission that would bring humanity back to the lunar surface. The Orion crew module carrying the mission’s astronauts separated from the service module at 7:33 PM. While the service module was designed to burn up in the Earth’s atmosphere, the crew capsule was built to bring the astronauts back home safely.
By 7:53 PM, Orion reached our planet’s upper atmosphere, where a six-minute communication blackout occurred due to the capsule heating up as it started its guided descent. The capsule has 11 parachutes, with its drogue parachutes being deployed at 23,400 feet to stabilize and slow it down. When Orion reached 5,400 feet above the ground, the drogue parachutes were cut off so that the three main parachutes could be deployed. That decreased the capsule’s velocity to 200 feet per second, enabling a safe splashdown.
NASA’s engineers conducted several tests while the capsule was in the water before the recovery team headed to the capsule on inflatable boats to extract the crew from Orion. By 9:34 PM, all four crew members were out of the capsule. They were then hoisted into helicopters and flown to the USS John P. Murtha dock ship, where doctors will assess their health.
Artemis II launched on April 1 with four astronauts on board: NASA’s Reid Wiseman, Victor Glover and Christina Koch, as well as Canadian Space Agency’s Jeremy Hansen. They traveled around the moon for almost 10 days, reaching distances no other crewed mission has before it. The astronauts took photos of the far side of the moon, the side we don’t see from our planet, including amazing closeups of the lunar surface using their smartphones. That makes them the first humans to directly and personally view the lunar far side.
During NASA’s post-splashdown news conference, the agency said it will announce the Artemis III crew soon. Artemis III will rendezvous with one or both commercial landers being developed by SpaceX and Blue Origin in low Earth orbit, which will take humans to the lunar surface. It will test the lander’s ability to dock with Orion before NASA lands humans on the moon again.
Welcome home Reid, Victor, Christina, and Jeremy! 🫶
