International Space Station getting rewired

The astronauts onboard the international space station are working on rewiring the ISS. This job when finished would let the orbiting outpost double the size of its crew. They would also be able to add two more laboratories.

Flight controllers on the ground confirmed that the power was flowing through two electrical channels hooked up by astronauts Robert Curbeam and Christer Fuglesang.

NASA has also started powering up systems aboard a large section of the space station. It had to be turned off initially to let the work on rewiring begin.

This rewiring work involves switching the space station from its old, temporary power source to its new one. They would be hooking up the pair of solar arrays that were delivered in September.
