He is on top of the world — both physically and emotionally.

Astronaut Chris Hadfield is not wasting a single minute of his time in space because this is an experience of a lifetime, he said in his first news conference since becoming commander of the International Space Station last Wednesday.

He is the first Canadian to do so.

“My resolution has been to make the absolute most of it, to spend as little time sleeping as I can,” he said.

“If I get an extra three or four minutes, go look out the window. When I get back from this, I’m going to regret every minute that I didn’t spend looking at the world.”

His five-month visit, which began in late December, ends in mid-May.
