斯科特凯利和他的兄弟马克都申请成为宇航员并于1996年被接受。斯科特接受过国际空间站的警告和警告系统培训。他的第一次飞行是乘坐哈勃太空望远镜维修任务STS 103上的Discovery号航天飞机。他的下一个任务是将他带到俄罗斯的星城，在那里他担任俄罗斯 – 美国联合航班的运营总监。他还担任过几次国际空间站任务的机组人员的备用。由于2002年哥伦比亚事故（他为此飞行搜索和恢复行动），航班被推迟到NASA可以调查悲剧的原因。斯科特接下来在休斯顿担任宇航员办公室空间站分局局长，然后在NEEMO 4任务中任职。佛罗里达州的水下训练实验室的开发是为了研究在模拟空间条件下在封闭区域内长时间生活在太空和水下的相似性。凯利的下两个航班是前往国际空间站的STS-118，以及25和26号探险队，他在那里工作了几个月。他参与了为该站安装仪器以及各种科学实验。
Scott Kelly and his brother Mark both applied to become astronauts and were accepted in 1996. Scott has received training in warning and warning systems from the International Space Station. His first flight was the Discovery space shuttle on the Hubble Space Telescope maintenance mission STS 103. His next assignment was to take him to the Star City of Russia, where he served as the Director of Operations for the Russian-US joint flight. He also served as a backup for several crew members on the International Space Station mission. Due to the 2002 Columbia accident (he searched and resumed operations for this flight), the flight was postponed to NASA to investigate the cause of the tragedy. Scott then served as the Director of the Space Station of the Astronaut Office in Houston and then served on the NEEMO 4 mission. The Florida Underwater Training Laboratory was developed to study the similarities of living in space and underwater for long periods of time in enclosed areas under simulated space conditions. Kelly’s next two flights are the STS-118 to the International Space Station, and the 25 and 26 expeditions, where he worked for several months. He participated in the installation of instruments and various scientific experiments for the station.
