Nasa loses space station contact
The International Space Station has lost contact with Nasa controllers in Houston, officials said.
However, Nasa said the six crew members and station are fine and they expect to fix the problem soon.
Nasa spokesman Josh Byerly said something went wrong during a computer software update on the station. The outpost abruptly 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 all was well and they were working on the problem.
Mr Byerly said the problem should be fixed later. Until then, astronauts can talk with Moscow control for a few minutes every 90 minutes.
