任务简介
STS-125，即HST-SM4（哈勃太空望远镜第4次维修任务），是第五次也是最后一次前往哈勃太空望远镜（HST）的航天飞机任务。亚特兰蒂斯号航天飞机为哈勃太空望远镜携带了两台新仪器：宇宙起源光谱仪和广角相机3。该任务还更换了一个精细导星传感器、六个陀螺仪和两个电池单元模块，以使望远镜至少能运行到2014年。机组人员还安装了新的隔热毯绝缘板以提供更好的热保护，以及一个软捕获机构，该机构将有助于在望远镜运行寿命结束时由无人航天器安全地将其脱离轨道。
原文
STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final space shuttle mission to the Hubble Space Telescope (HST). Space Shuttle Atlantis carried two new instruments to the Hubble Space Telescope, the Cosmic Origins Spectrograph and the Wide Field Camera 3. The mission also replaced a Fine Guidance Sensor, six gyroscopes, and two battery unit modules to allow the telescope to continue to function at least through 2014. The crew also installed new thermal blanket insulating panels to provide improved thermal protection, and a soft-capture mechanism that would aid in the safe de-orbiting of the telescope by an unmanned spacecraft at the end of its operational lifespan.
