It's a big day for Chris Hadfield as he becomes the first Canadian commander of the International Space Station (ISS).
To celebrate, we thought we'd share this neat video of Hadfield talking about how food tastes in space with students from Airdrie, Alberta.
The answer? Different, at first.
Turns out, the body takes time to adjust to zero-gravity and during the first few days, astronauts' sinuses are full, so they can't taste much of anything.
But after that, everything gets back to normal.
In the video, Hadfield also shows off some of the food he's got up there, including a quintessentially Canadian delicacy - maple syrup in a tube.
As for today's changing of the guard, Hadfield has been dreaming of this moment for quite a while.
"In truth, I started training to command the space station when I was 14," he told University of Waterloo students from the ISS last month, CBC News reports.
"I was in the Air Cadets and I went to a junior leaders' course and they taught me the basic precepts of leadership at 14 years old as a young Canadian, and since then I've watched leaders, and you can learn something from every leader."
Hadfield takes over from American Kevin Ford, who's flying back to Earth this week with two Russian colleagues.
Another group of astronauts arrives at the station at the end of the month, leaving Hadfield in command of two American and three Russian crew members.
The Queen sent Hadfield an official message today as he takes command:
"I am pleased to transmit my personal best wishes, and those of all Canadians, to Colonel Christopher Hadfield... Our thoughts and best wishes are with him and the entire crew, as are our prayers for an eventual safe return to family, friends and fellow Canadians."
With such a long mission, Hadfield will have to make sure each crew member gets some personal time and connects with family and friends.
"Astronauts, we're typically Type A behaviour people. We'd work all 24 hours if it was totally up to us. But I think it's important for Chris to be aware of the well-being of each of his five crewmates," said retired Canadian astronaut Bob Thirsk in an interview with CBC prior to the mission.
Hadfield has also become a social media star, with more than half a million Twitter followers (check out his @Cmdr_Hadfield account).
His son Evan spoke with Matt Galloway on CBC Toronto's Metro Morning about how it feels to watch his dad take on dangerous missions, and how he ended up managing his dad's social media profile.
Check out that conversation on Metro Morning's site.
Hadfield also collaborated with the Barenaked Ladies' Ed Robertson on a song called 'I.S.S. (Is Somebody Singing)'.
Robertson was in the red chair recently, and talked about working with an out-of-this-world collaborator:
