美国宇航局当地时间29日宣布,继出现电源故障之后,哈勃太空望远镜的主照相仪又遭重创,丧失了三分之二的观测能力。据美宇航局介绍,望远镜上的高级巡天照相仪再次关闭,这是在不到一年内第三次出现类似故障。目前正绕轨道运行的哈勃太空望远镜已于27日晨进入保护性的“安全模式”,美宇航局对这一故障初步调查表明,该照相仪的备用电源已经损坏。不过哈勃望远镜有望使用其它设备于本周继续执行观测任务。
NASA announced on the 29th local time that following the power failure, the Hubble Space Telescope’s main camera was hit again and lost two-thirds of its observation capacity. According to NASA, the high-level survey camera on the telescope was closed again, which was the third time a similar failure occurred in less than one year. The Hubble Space Telescope currently orbiting has entered a protective “safety mode” on the morning of the 27th. NASA’s preliminary investigation of this failure showed that the camera’s backup power supply has been damaged. However, the Hubble Space Telescope is expected to use other equipment to continue its observation mission this week.
