On Friday, fog and freezing rain at the landing site in Kazakhstan prevented helicopters from setting up for the crew’s return to Earth.
In preparation for their departure, Canadian astronaut Chris Hadfield took the helm of the space station on Wednesday, becoming the first Canadian to take command of the outpost.
It is only the second time in the 12-year history of the station, a project of 15 nations that has been permanently staffed since November 2000, that command has been turned over to someone who is not American or Russian.
Hadfield will be part of a three-man skeleton crew until NASA astronaut Chris Cassidy and cosmonauts Pavel Vinogradov and Alexander Misurkin arrive later this month.
