Nasa to launch emergency spacewalk after International Space Station computer breaks

Astronauts are having to climb into space to fix a computer in an emergency move. Two inhabitants of the International Space Station (ISS) will have to venture out on a spacewalk to repair a computer part – a data relay box – that broke over the weekend. The broken computer means that the lab is floating over the Earth relying only on its second computer, potentially putting the astronauts on board at risk. From the International Space Station, Expedition 42 Flight Engineer Terry W. Virts took this photograph of the Gulf of Mexico and U.S. Gulf Coast at sunset This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater. The image was taken by Nasa's HiRISE camera, which is mounted on its Mars Reconaissance Orbiter The Soyuz TMA-15M rocket launches from the Baikonur Cosmodrome in Kazakhstan on Monday, Nov. 24, 2014, carrying three new astronauts to the International Space Station.
