Canadian astronaut Chris Hadfield is packing his bags as he wraps up his five-month mission aboard the International Space Station.
Hadfield tweeted this morning that he "proudly" hands command of the station to Pavel Vinogradov, a Russian cosmonaut.
He also tweeted that it's "time to rev up the Soyuz" for the trip home.
Plans call for Hadfield and two other crewmembers to leave the station Monday just after 7 p.m. E-T aboard a Russian Soyuz spacecraft.
They're due to land in Kazakhstan about three and-a-half hours later.
A helicopter will take them to a local airport, where a waiting NASA plane will fly them to Houston, Texas.
