The Soyuz TMA-06M spacecraft, with two Russian cosmonauts and a NASA astronaut aboard, is scheduled to land 30 miles north of the town of Arakalyk at 7:06 a.m. Moscow time (10:06 p.m. EST Friday), Russia's Federal Air Transport Agency Rosaviatsia said.
Weather conditions had forced the Russian space agency Roscosmos to postpone the undocking and landing of the Expedition 34 crew members -- Oleg Novitsky, Yevgeny Tarelkin and NASA astronaut Kevin Ford -- by one day, RIA Novosti reported.
The three have been aboard the ISS since October.
Later this month, three new crew members -- Russian cosmonauts Pavel Vinogradov, Alexander Misurkin and NASA astronaut Christopher Cassidy -- will launch to the ISS aboard a Soyuz TMA-08M spacecraft.
They will join the current ISS crew of cosmonaut Roman Romanenko, U.S. astronaut Thomas Marshburn and
Canadian astronaut Chris Hadfield, who took over as ISS commander from Ford on Wednesday.
