国际空间站乘组因医疗问题提前返回

NASA启动了首次从国际空间站(ISS)的医疗撤离行动,因一名乘员出现严重但未披露的健康问题,将四名宇航员提前送回地球。该团队包括两名美国人、一名日本宇航员和一名俄罗斯宇航员,比原计划提前一个多月在太平洋海域溅落。此举优先考虑地面医疗护理,同时确保该宇航员的稳定状况。

SpaceX“龙”飞船于2026年1月14日星期三从国际空间站脱离,搭载四名乘员进行紧急返回飞行,此举由一名宇航员的严重但未披露的医疗状况引发。NASA于1月8日宣布此事,这是该机构65年人类太空飞行史上首次医疗撤离行动。 返回的乘员包括NASA宇航员泽娜·卡德曼(38岁),她是一名生物学家和极地探险家,此次为首次太空飞行,以及指挥官迈克·芬克(58岁),他是一位退役空军上校,拥有四次任务和九次太空行走经历。他们与日本宇航员由井龟美也(55岁)同行,后者是一位前战斗机飞行员,此次为第二次飞行,最近累计太空时间达300天,以及俄罗斯宇航员奥列格·普拉托诺夫(39岁),他是一位前战斗机飞行员,此次为首次任务,曾因健康问题推迟。该团队于2025年8月发射,原计划停留至2月底,但将167天的任务缩短了一个多月。 脱离时间约为美国东部标准时间下午5:20,计划于1月15日星期四早间在加利福尼亚海岸外太平洋海域溅落,下降过程历时10.5小时。“此次离开的时机出乎意料,”卡德曼在出发前表示,“但令我并不意外的是,这个乘组如何像家人一样团结起来,互相帮助和照顾。” 受影响的宇航员“状况稳定、安全且得到良好照顾”,芬克在本周早些时候在社交媒体上表示。“这是一个深思熟虑的决定,以便在地面进行适当的医疗评估,那里有完整的诊断能力。”官员强调,此事与空间站运行或1月7日取消的太空行走无关,也非紧急情况,并援引医疗隐私规定。 NASA新任局长、亿万富翁贾里德·艾萨克曼于12月上任,他表示:“宇航员的健康和福祉始终是我们最高优先事项。”目前,ISS上仍有1名美国人和2名俄罗斯宇航员,他们的任务已进行1.5个月,原计划为8个月。NASA和SpaceX计划将下一批乘员从佛罗里达的发射提前至2月中旬。此次撤离让人联想到1985年的苏联案例,但对NASA而言尚属首次,暂时使空间站乘组减半,并暂停太空行走。

NASA's Artemis II astronauts are returning to Earth after a 10-day journey to the far side of the moon, with splashdown scheduled for Friday evening. The agency will livestream the historic homecoming. NASA administrator Jared Isaacman stated that the mission is not over until everyone arrives home safely.

NASA has named veteran astronaut Mike Fincke as the crew member who suffered a medical event on the International Space Station (ISS), leading to the historic early return of the Crew-11 mission—the first medical evacuation from the ISS in 25 years.

NASA's Artemis II crew returned to Earth on Friday, splashing down in the Pacific Ocean west of San Diego after a 10-day journey that circled the moon. Commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch and Canadian astronaut Jeremy Hansen emerged healthy from the Orion capsule named Integrity. The mission marked several historic firsts and set a new record for human distance from Earth.

NASA has set March 6 as the earliest possible launch date for the Artemis II mission following a successful second fueling test of its Space Launch System rocket. The test at Kennedy Space Center resolved issues from an earlier attempt marred by a hydrogen leak. The mission will send four astronauts around the Moon in a crewed test of the Orion spacecraft.

Following their successful launch, NASA's Artemis II astronauts aboard the Orion spacecraft resolved a jammed toilet fan and Microsoft Outlook software glitches during the initial phase of their 10-day lunar orbit mission. The crew—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Jeremy Hansen and Christina Koch—marks historic firsts: Glover as the first Black astronaut, Koch the first woman, and Hansen the first Canadian to venture toward the moon.

NASA has delayed the Artemis II mission to April 1 following a helium flow problem that rolled the rocket back from the pad, building on prior fixes for hydrogen leaks during fueling tests. This first crewed lunar orbit since 1972 faces ongoing maintenance before returning to the launch site.

NASA Administrator Jared Isaacman told lawmakers that SpaceX and Blue Origin expect their lunar landers to be ready for the Artemis III mission in late 2027. The mission will now test the landers in Earth orbit rather than attempting a lunar landing. This change aims to reduce risks and increase launch frequency.
