A 31-year-old engineer from Calgary is one step closer to a shot at space travel.

Zac Trolley is among 200,000 people around the world who applied to take part in the first mission to set up a colony on Mars.

Trolley is one of the 1,000 people who made the short list.

"I think I have the skill set that's needed," he said. "I'm healthy and I'm willing to go."

Space travel been a lifelong dream for Trolley and he hopes to make the final cut.

"With astronauts, even nowadays, they say if you're not a little bit scared you're not telling the truth. These are big machines, these are high risks, but the payoffs are also pretty big, so I'm looking forward to it."

Trolley's health will be assessed in the coming months to see if he is suitable for the mission.

Founders of the $6-billion Mars One Mission have turned to crowdsourcing to raise the funds.

The plan is to build machinery and train people over the next 10 years before sending the first group of colonizers by 2025.
