Go Away With … Mark C. Lee

Before retiring, Mark C. Lee flew on four NASA space flights, traveled more than 13 million miles, circled the globe 517 times and did an untethered spacewalk. In 1992, he and his then-wife, Nancy Jan Davis, made history by becoming the first married astronauts to fly together in space.

Go Away With … Col. Chris Hadfield

“Travel has always been such an important part of my life,” says Canadian astronaut Col. Chris Hadfield. “It has been wonderful to have been around the world multiple times and to have seen the whole thing. It has been one long whirlwind vacation.” Well versed in social media, Hadfield, 54, had a strong following of science fans before he went up in space. But he garnered the attention of millions of music fans when he released his rendition of David Bowie’s “Space Oddity” on YouTube, which was recorded from the International Space Station during his last mission earlier this year. The video went viral and earned kudos from no less than Bowie himself.
