Canadian Space Agency narrows astronaut candidates down to 17

They are doctors, they are engineers, they are scientists and they are the next group of Canadians who may one day find themselves staring down on Earth from the International Space Station.

On Monday, the Canadian Space Agency together with Navdeep Bains, Minister of Innovation, Science and Economic Development, announced the newest 17 astronaut candidates, the last remaining from 3,772 applicants. The list will be narrowed downthis summer to the final two.

These Canadians have undergone rigorous physical and mental testing in Quebec and Halifax. The tests are designed to leave them exhausted andfrustrated and to see how they performed under unusually difficult conditions.

Vanessa Fulford, originally from Fort McMurray, Alta., was one of the latest candidates to make the cut.

"It was a difficult process, but something I've wanted to do all my life," she told CBC News.

Fulfordstudied space science as well as flight test engineering before workingas an aerospace engineer in the RoyalCanadianAir Force. Today she isflight test engineer, and saysher experience there helped her prepare for her training as an astronaut.

"I work in a team, under stressful circumstances," she said. "You're used toworkingas a team and communicating effectively and also working in the close quarters of an aircraft. So it's something that I do in my everyday job."

As a child,Fulfordalways had an avid interest in science. But her goal to become an astronaut was ignited during a family trip to Florida where she watched a night launch of the space shuttle Endeavour.

"Just watching that, I'd never had a feeling like that beforewatching those astronauts blast off into the most amazing adventure. So from then onI knew that's what I wanted to be."

As for being one of five female astronaut candidates,Fulfordsaid she's happy, but had never been deterred from applying to traditionally male-dominated careers in the first place.

"In my experience so far, in both the military and this new process, is that I'm treated as a personI'm a flight test engineer, I'm an astronaut candidate. I'm looked at for my qualities, my skills and not my gender."

Fulfordultimately hopes to inspirefuture generations and also young girls who may not look to careers in science. And, of course, she has her sights set on something big.

"I could get on a mission to Mars," she said. "I think that would be the ultimate exploration."

Jesse Zroback, who works as a doctor in Marathon, Ont., was also one of the final candidates.

"It has been a life-changing experience," he said.

Zroback said the training was exhausting: they had limited sleep, tested with military trainersand took part in activity after activity for 14 hours straight.

"They do a really good job of layering the different stress factors to see how you'll be able to perform," he said. But the most challenging part for himwas the unknown.

"In Halifax, they'd give you an Arctic dry suit," he said. "So you knew they could throw anything your way, whether it's jumping in a wave pool that's simulating a storm in the ocean, or the next thing they could do is some hand-eye co-ordinationtest, or the next could be some problem-solving test that you have to write on paper. So you just don't know what's coming next."

Words of advice

While training for theas-yet-unannounced future mission to space, astronaut Jeremy Hansen has been also been working closely with the recruitment program. It brings back some memories of his own recruitment process, and the challenges he faced.

"The floodscenarios, the fire scenarios I mean, it was exhausting," he told CBC News. "And your body was just saying, 'I'm done.' But you keep on going."

As for words of advice to the newest shortlisted candidates, Hansen said theyshould be proud of what they've accomplished.

"You've proven yourselves;you're great examples," he said. "We know you're not perfectso just be yourself."
