标题: NASA猎户座飞船成功返回地球
NASA猎户座飞船“Integrity”于周五以超过音速30倍的速度冲入大气层,安全降落在太平洋,搭载四名宇航员完成近54年来人类首次绕月飞行任务。飞船外部温度高达约5000华氏度,等离子层导致与休斯顿任务控制中心通信中断六分钟。
飞船从西南向东北飞行,精准驶向圣地亚哥西南海域的溅落区,美国海军“约翰·P·默萨”号两栖运输舰已就位待命。地面团队在通信恢复后确认指挥官里德·怀斯曼状态正常。
空中追踪飞机实时传回降落画面,显示飞船依次抛离降落伞罩、展开稳定伞,最终三具总面积达31500平方英尺的主降落伞打开,使飞船于美东时间晚8:07安全溅落。

标题: 四名宇航员顺利出舱接受医疗检查
四名宇航员在溅落后依次出舱,克里斯蒂娜·科赫首先离开飞船,登上充气筏“前门廊”,随后维克多·格洛弗和加拿大宇航员杰里米·汉森相继出舱。指挥官怀斯曼最后离开,确认全员状态良好。
海军潜水员协助宇航员转移至运输舰,两架直升机待命提供支援。初步检查显示四人生命体征稳定,情绪积极,未报告明显不适。
此次成功返回标志着阿尔忒弥斯二号任务圆满完成,为后续登月任务奠定关键基础。回收流程高效有序,验证了深空载人返回系统的可靠性。

标题: 猎户座飞船再入过程承受极端条件
飞船在14分钟内将速度从近25000英里每小时降至安全水平,期间宇航员经历两次约3.9倍重力加速度的冲击。高温等离子层包裹舱体,短暂阻断通信信号。
降落伞系统分阶段展开,确保飞船稳定减速。三具主降落伞每具面积达10500平方英尺,有效控制下降速度,保障溅落安全。
此次再入数据将为未来深空任务提供关键参考,验证飞船热防护与导航系统的实际性能。

- NASA Orion Spacecraft Completes Historic Moon Mission with Safe Pacific Splashdown
NASA’s Orion spacecraft, named Integrity, successfully returned to Earth on Friday after completing humanity’s first crewed lunar voyage in nearly 54 years. The capsule reentered Earth’s atmosphere at over 30 times the speed of sound, enduring external temperatures reaching approximately 5,000 degrees Fahrenheit. A plasma sheath formed around the spacecraft, causing a six-minute communications blackout before contact was restored with commander Reid Wiseman.
The descent was tracked by airborne planes that relayed live video to Mission Control in Houston. Orion deployed a series of parachutes, including three main chutes each covering 10,500 square feet, to slow its descent before splashing down southwest of San Diego at 8:07 pm EDT. In just 14 minutes, the spacecraft reduced its velocity by nearly 25,000 mph, subjecting the crew to two brief periods of 3.9 Gs.
Recovery operations were conducted by the USS John P. Murtha, which deployed helicopters and small boats to retrieve the crew. All four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—were reported in good health. Koch exited first, followed by Glover and Hansen, with Wiseman last. The successful mission marks a critical milestone for NASA’s Artemis program.
Key Takeaways:
NASA completes first crewed Moon mission in 54 years
Orion spacecraft endures extreme reentry conditions safely
All four astronauts recovered in good health after splashdown
Artemis II mission advances future lunar exploration goals
