Yellowknife students were among the Canadians to have one last chat with astronaut Chris Hadfield before he began the final preparations for his trip home from space.

About 75 students and parents were at the RCMP detachment in the city Sunday to ask the astronaut just 20 questions. Everything from, "can you watch movies in space" to "how do you go to the bathroom in space."

Students had exactly nine minutes to ask their questions. Alex Ketchum, seven, said the whole experience was pretty cool.

"I mean, he's an astronaut. He's like, in space. So that's really exciting."

Hadfield, as usual, charmed the audience with his personal touch.

"The coolest thing is the northern lights coming up underneath my feet. They are beautiful. They're even prettier than they are in Yellowknife," Hadfield said.

Just a few hours after the talk, Hadfield handed over command of the space shuttle to Russian cosmonaut Pavel Vinogradov.

He's expected to land in Kazakstan Monday night at 10:31 ET. CBC’s live coverage begins at 3:50 p.m.
