" If Chris Hadfield weren&amp;#039;t married, he would be the perfect guy to set up with Martha Stewart. Not only does he possess a handsome moustache, he&amp;#039;s also used to living in industrial conditions of extreme hygiene. He also has a sense of humor, bringing a much-needed jolt of charisma to space. As commander of the International Space Station for the past three months, he has had, if not the most successful, then at least the most widely publicized run in the Space Station&amp;#039;s history. In the future, a good singing voice and ability to play the guitar may well become requirements for astronauts.  There have been questions for a while about the point of space travel. When Neil Armstrong died last summer, it was hard to see who could replace him as an icon of human potentiality. We&amp;#039;re not going to space to prove the limits of ourselves anymore. The coolest things we send to other planets now are machines. Hadfield is no Armstrong, of course, but he has found a new role for the old profession of spaceman. He is the astronaut as entertainer. It may be just as good as any of the other reasons we have ever had for leaving the planet. We go to space because it&amp;#039;s awesome. Since Hadfield is returning to earth today, here&amp;#039;s a brief guide to the greatest hits from his season in the sky. It began with a duet with the Barenaked Ladies:      He took some of the most amazing pictures of earth you&amp;#039;ll ever see:      He described just how freaky it is to live in space:      And he gave one of the best Bowie covers ever:      It&amp;#039;s going to be a tough act for new commander Pavel Vinogradov to follow. At least he has nearly as good a moustache.       Follow The Culture Blog on RSS and on Twitter at @ESQCulture. "^^<http://www.w3.org/2001/XMLSchema#string>
