Former NASA astronaut Shane Kimbrough is photographed as he left the airlock hatch during a spacewalk on Jan. 13, 2017. Kimbrough performed nine spacewalks during his three spaceflights. He retired in July 2022.
Astronauts conduct spacewalks to perform maintenance on the space station, install new equipment, or deploy science experiments. These activities also inform future missions like the Artemis campaign and exploring Mars; through NASA’s Extravehicular Activity and Human Surface Mobility Program, the agency develops next-generation spacesuits, human-rated rovers (pressurized and unpressurized), and tools, along with all the necessary spacewalking support systems for use in microgravity, on the lunar surface and, eventually, on other planets.

前美国国家航空航天局（NASA）宇航员谢恩·金布罗在2017年1月13日进行太空行走时，被拍摄到正从气闸舱口离开的瞬间。金布罗在三次太空飞行中共完成了九次太空行走，并于2022年7月正式退役。
宇航员进行太空行走，通常是为了维护空间站、安装新设备或部署科学实验。这些活动也为未来的任务提供了宝贵经验，例如“阿耳忒弥斯”计划和探索火星。通过NASA的舱外活动与人类地表移动计划，航天局正在研发新一代宇航服、适用于人类的探测车（包括加压与非加压型）、工具，以及所有必需的太空行走支持系统，以满足微重力环境、月球表面乃至未来其他行星任务的需求。
