( CNN ) -- Two cosmonauts and an American astronaut were on their way back to Earth from the International Space Station Saturday morning after engineers used jumper cables to fix a glitch that delayed their departure , NASA said . The trio undocked from the space station in a Russian Soyuz spacecraft at 10:02 p.m . ET , NASA said . They are scheduled to land in Kazakhstan on Saturday morning after spending 176 days in space and 174 aboard the station . An undocking glitch earlier had delayed the departure of Cmdr . Alexander Skvortsov and flight engineers Mikhail Kornienko and Tracy Caldwell Dyson . NASA said the opening hooks and latches on the docking port would not release . To resolve the problem , flight engineer Fyodor Yurchikhin installed jumper cables to a failed sensor Friday , allowing the hooks to open . According to NASA , a Soyuz space capsule took the first crew to the orbiting laboratory in November 2000 . After the February 2003 Columbia accident , the Soyuz became the means of transportation for crew members going to or returning from the International Space Station . CNN 's Ninette Sosa contributed to this report .
