Soyuz capsule undocks from space station

ALMATY, Kazakhstan — A manned Soyuz capsule with two Russian cosmonauts and an American astronaut onboard has successfully undocked from the International Space Station after crew resolved glitches that had prevented departure a day earlier.
Undocking had been thwarted by signaling errors in the onboard computer system and a malfunction with the opening hooks and latches on the space station side of the capsule.
American astronaut Tracy Caldwell-Dyson and Russia's Alexander Skvortsov and Mikhail Kornienko are due to land at 11:21 a.m. local time (0521 GMT) in the barren steppes of Kazakhstan.
The astronauts have been onboard the space station for almost six months.
Friday's incident was the second problem in three months with docking or undocking Russian craft at the space station.
