The first Canadian commander of the International Space Station, Chris Hadfield, is scheduled to return to earth this evening with U.S. astronaut Tom Marshburn and Russian cosmonaut Roman Romanenko.
Hadfield's been in orbit for 148 days, and during that time he's not only done whatever it this they do on the ISS, he's maintained constant contact with the people of this strange little blue ball via Twitter and other media. But he obviously saved the best for last.

Godspeed, guys. May you have a safe and uneventful landing.
And eat your heart out, William Shatner.
