NASA loses regular communication with ISS
The U.S. space agency NASA announced on Tuesday that flight controllers lost regular communication with the International Space Station (ISS) in the morning, but the station was fine and the crew was doing well.
According to an alert from NASA, Houston's Mission Control was updating software of the space station's onboard flight computers at 8:45 a.m. EDT (1245 GMT) when one of the station's data relay systems malfunctioned. Although a backup computer took over critical station functions from the primary computer, the station lost all communication, voice and command from Houston.
About an hour later, while flying over Russia, station commander Kevin Ford was able to briefly radio Moscow that everyone was well and they were working on the problem.
"This is the same way they used to do it in the 1960s, with Gemini and Apollo," NASA spokesman Josh Byerly said. "The crew is working on this, and they'll get it back up and running."

The ISS, which is carrying one American astronaut and two Russian cosmonauts, does not appear to be in danger.
"It's not a panicked mood that takes over mission control," Byerly said. "Anybody who's been here has seen that."
Byerly said the problem should be fixed later on Tuesday. Until then, astronauts can talk with Moscow control for a few minutes every 90 minutes.
美国航天局19日发布消息称，国际空间站当天在进行软件升级时与休斯敦地面控制中心失去日常通信联络，不过宇航员一切安好。
美国航天局表示，美国东部时间8时45分(北京时间21时45分)，国际空间站的飞行计算机在进行日常升级时，其中一个数据中继系统出现故障，尽管备用计算机立即“接管”了主计算机的主要功能，但空间站突然失去来自控制中心的通信、语音和命令。大约一小时后，空间站指令长凯文·福特联系上莫斯科地面控制中心，告知他们一切安好并在处理故障。
航天局发言人乔希·拜尔利当天表示，类似情况以前曾多次出现，控制中心工作人员都见识过，因此“控制中心并没有被惊慌情绪左右”。
目前，空间站共有3名宇航员，其中福特为美国人，另两人为俄罗斯宇航员。空间站故障预计将于19日得到解决。在此之前，宇航员只能每90分钟与莫斯科地面控制中心短暂联络一次。 |
