Canadian Chris Hadfield blasts off into space for 3rd time

Canadian astronaut Chris Hadfieldblasted offinto space this morning aboarda Soyuz spacecraft and is on his way to the International Space Station, where he is set to make history.

Hadfield, American Tom Marshburn and Russian Roman Romanenko lifted off at 7:12 a.m. ET (6:12 p.m. local time) in the freezing steppes of Baikonur, Kazakhstan, where temperatures were hoveringaround30 C.

The astronauts could be seen waving, and giving the thumbs-up inside the spacecraft.

Just a few hours after the launch, Hadfield's sons took over their father's Twitter account and posted a message. "The Soyuz launch was an incredibly emotional experience," they wrote."Godspeed, Dad. Your achievement has literally brought us all to tears."

Hadfield's sons will be posting on his Twitter account over the next few days.

The current Soyuzis an upgraded version of theunmanned spacecraftfirst used by the Soviet space program in 1966.

All three had been in Baikonur for the past two weeks to prepare for the trip, which includes a two-day journey to the International Space Station, where they will be in orbit forfive months. Hadfield will take over command of the ISS in Marchthe first time a Canadian has done so.

"Yes I'll take it seriously and yes it's important for Canada, but for me as just a Canadian kid, it makes me want to shout and laugh and do cartwheels," Hadfield told CBC News recently.

The crewwill spend 147 days in orbit before their scheduled landing on May 14.

Canadians at home and abroad will be watching Hadfield's journey closely. Gov. Gen. David Johnston joined other officials at the Canadian Space Agency east of Montrealon Wednesdayto watch the spacecraft carrying the Canadian astronaut blast off.

"What a great day to be here at the Canadian Space Agency, a great day for Canada, a great day for the world of discovery and innovation," Johnston said."We're so proud that Chris Hadfield is now up in space, the first Canadian to be commanding the space station."

Former Canadian astronaut Robert Thirsk, who also watched the launch from thespace agency,added, "Pride is what I feel. I'm part of this Canadian astronaut corps which has existed for over a quarter century now. We've taken small baby steps which have culminated today."

Hadfield, aMilton, Ont., native, still cant believe what he's about to do.

"You expect someone to come in and go, 'Wait a minute, you aren't a guy that could command a spaceship, come on.' You expect to get busted by somebody because it's just such an unlikely thing to ever happen in your life, and so it absolutely thrills me just as a person."

Influences include Star Trek

For Hadfield, its a pinnacle of achievementthats been 20 years in the making.

ACanadian Forces fighter pilot with a mechanical engineering degreefrom the Royal Military College in Kingston, Ont., Hadfield was chosen to become one of four new Canadian astronauts in 1992.

Since then, he's flown on two NASA space shuttle flights and was the first Canadian to operate the Canadarm in orbit. He has done two spacewalks, and was the first Canadian to float freely in space. Training for the space station mission has consumed the past four years.

Among his many influences, he names the movie 2001: A Space Odyssey and the TV series Star Trek, recalling that one of his childhood heroes was fictional: "You know, James Tiberius Kirk commanding the Enterprise."

Hadfield says he didnt need another space flight for personal fulfilment.

"I instead feel an obligation to fulfil this role, to do this thing right. I would not have felt hard done by if I didnt get a third space flight."

Nonetheless, he is going on another space journey and orbiting for six monthsquite long for a human body, which means the muscles, the heart and bones tend to atrophy.

'An incredible accomplishment'

Marc Garneau, the first Canadian to shuttle into outer space, says he's proud of Hadfield's accomplishments and wishes him well.

"This is a first," he said Tuesday. "The first [Canadian] commander of the International Space Station."

"That's an incredible accomplishment. He's an incredible guy."

Thirsk, the last Canadian astronaut to gointo space for a long-duration flight,said he hadoffered one piece of advice to Hadfield: enjoy it.

"Just to enjoy the fact that you're up there. Take time to look out the window, fly around like Superman.Make sure you enjoy those moments. That's what you'll miss the most when you come back home."

Space music

One of the things Hadfield is looking forward to aboard the ISS is a special song set to premiere on Feb. 8, which will be featured on CBC-TV, radio and CBCMusic.ca

"It'll be really nice to be able to play music, to try and capture the experience as best I can," Hadfield said of his song about space flight, Is Somebody Singing? or ISS, which he wrote with Ed Robertson of the Barenaked Ladies.

Starting in January,CBCMusic will team up with Hadfieldand Robertson to produce a series of blog posts, behind the scene photo galleries and playlists.

Also while aboard the ISS, Hadfieldwill also be involved with more than 130 experiments, including Microflow, a Canadian blood-sampling experimentthat he compared to a hospital in a box.
