CAPE CANAVERAL, Fla. (AP) - Two Russian space station astronauts took a spacewalk Monday to complete a camera job left undone last month.
    
Oleg Kotov and Sergey Ryazanskiy ventured outside the International Space Station 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 in.
    
The problem was traced to indoor cabling and fixed, according to NASA.
    
Images from these new cameras will be distributed by the Canadian company that owns them, UrtheCast (pronounced EARTH-cast)Corp.
    
The cameras were launched to the space station last November in a deal between the Vancouver-based UrtheCast and the Russian Space Agency.
    
UrtheCast will post near-real-time video on its website, and sell images as well. The company envisions customers wanting video feed for environmental, agricultural and humanitarian purposes.
    
One camera is high-definition, the other medium resolution.
    
Because of all the camera data trouble during the Dec. 27 spacewalk, which dragged on for eight hours, Kotov and Ryazanskiy had to put off other chores. Those tasks were on Monday's to-do list.
    
The four other space station astronauts - two Americans, one Japanese and another Russian - kept tabs on the spacewalk from inside.
    
Russian flight controllers outside Moscow directed Monday's 260-mile-high excursion.
