A pair of astronauts will venture outside the International Space Station as early as Tuesday for an emergency space walk to replace a failed computer, one of two that control major U.S. systems aboard the orbiting outpost, NASA said on Sunday.

The primary device failed on Saturday, leaving the $100 billion orbiting laboratory to depend on a backup system to route commands to its solar power system, radiators, cooling loops and other equipment.

The station's current five-member crew from the United States, Russia and France were never in any danger, the National Aeronautics and Space Administration said in a statement.

NASA expects to make a decision later on Sunday about which astronauts aboard the station will make the two-hour space walk and when the assignment will take place.

    Earlier on Sunday, Whitson assembled and tested a spare electronics box to replace the failed device, which had been installed during a spacewalk on March 30, said NASA spokesman Dan Huot.

    53 days of use before going bad ain't much. Did it fail due bad design? or radiation frying?

    Thursday’s spacewalk will see Kimbrough and Peggy Whitson complete the PMA-3 attachment work on the Harmony’s space-facing port. The duo will also install computer relay boxes containing software upgrades to enable future commercial crew vehicle dockings at the International Space Station.

    No remote upgrade and the computer has a bug? almost seems like the commercial approach to quality has finally reached ISS?

    Well, astronauts are pretty much being spied on at every step of their their work, comms, and movements, so getting phone-app quality code is par for the course.
