Crew-4机组人员在返航前合影

NASA’s SpaceX Crew-4 members Jessica Watkins, Bob Hines, Kjell Lindgren, and Samantha Cristoforetti link arms for a portrait on Oct. 14, 2022, just before boarding the Dragon Freedom crew ship and undocking from the International Space Station.

During their nearly six-month science expedition aboard the orbiting laboratory, the Crew-4 astronauts continued work on investigations documenting how improvements to the space diet affect immune function and the gut microbiome, determining the effect of fuel temperature on the flammability of a material, exploring possible adverse effects on astronaut hearing from equipment noise and microgravity, and studying whether additives increase or decrease the stability of emulsions.

NASA astronauts Watkins, Hines, and Lindgren, and European Space Agency astronaut Cristoforetti safely splashed down on Oct. 14, 2022, off the coast of Jacksonville. They recently answered questions about their mission aboard the International Space Station during an Oct. 20, 2022, news conference.

2022年10月14日，就在登上自由号载人龙飞船和离开国际空间站之前，NASA的SpaceX Crew-4机组人员杰西卡·沃特金斯、鲍勃·海恩斯、杰尔·林德格伦和萨曼莎·克里斯托弗雷蒂挽臂合影。

在轨道实验室近六个月的科学考察中，Crew-4机组人员继续进行研究，记录太空饮食的改善如何影响免疫功能和肠道微生物群，确定燃料温度对材料可燃性的影响，探索设备噪音和微重力对宇航员听力可能产生的不利影响，并研究添加剂是否会增加或降低乳液的稳定性。

2022年10月14日，NASA宇航员沃特金斯、海恩斯和林德格伦以及欧洲航天局宇航员克里斯托弗雷蒂在杰克逊维尔海岸外安全溅落。他们最近在2022年10月20日的新闻发布会上回答了关于国际空间站任务的问题。
