Space station power glitch could delay SpaceX launch plans

An electrical distribution unit aboard the International Space Station malfunctioned Monday, taking down two of the lab's eight power channels. The crew is in no danger while engineers troubleshoot the problem, officials said, but if it can't be resolved, the electrical box in question might have to be replaced with a spare, possibly prompting NASA to delay launch of a SpaceX Dragon supply ship Wednesday. Assuming an on-time launch atop a Falcon 9 rocket, the Dragon cargo capsule, loaded with nearly 5,500 pounds of equipment and supplies, is expected to catch up with the station early Friday and then stand by while the lab's robot arm locks on and pulls it in for berthing.
