Cape Canaveral - Two space station astronauts are making a spacewalk to complete a job left undone last month.
Russians Oleg Kotov and Sergey Ryazanskiy ventured outside the International Space Station on Monday to install a pair of commercially provided cameras.
The men hooked up the Earth-observing cameras during a spacewalk right after Christmas. But ground controllers received no data from the cameras, and the spacewalkers had to take everything back inside.
The problem was traced to indoor cabling and fixed.
Images from these new cameras will be distributed by the Canadian company that owns them, UrtheCast.
The cameras were launched to the space station in November in a deal between UrtheCast and the Russian Space Agency. UrtheCast will post video on its website and sell images.
