ISS Crew Install Cables For 2017 Arrival of Commercial Capsules 106
The Associated Press, as carried by the San Francisco Chronicle, reports that
NASA astronauts Butch Wilmore and Terry Virts have attached more than 300 feet of cable to the exterior of the International Space Station in a series of three planned spacewalks; in total, the wiring job they're undertaking will involve 764 feet of power and data cables.
The extensive rewiring is needed to prepare for NASA’s next phase 260 miles up: the 2017 arrival of the first commercial spacecraft capable of transporting astronauts to the orbiting lab.
NASA is paying Boeing and SpaceX to build the capsules and fly them from Cape Canaveral, which hasn’t seen a manned launch since the shuttles retired in 2011. Instead, Russia is doing all the taxi work — for a steep price.
The first of two docking ports for the Boeing and SpaceX vessels — still under development — is due to arrive in June. Even more spacewalks will be needed to set everything up.
Mission Control left two cables — or about 24 feet worth — for the next spacewalk coming up Wednesday. Four hundred feet of additional cable will be installed next Sunday on spacewalk No. 3.
