Nothing will keep Chris Hadfield from celebrating St. Patrick’s Day…Not even space!

You don't need gravity to have a great St. Patrick's Day, just ask astronaut Chris Hadfield on the International Space Station.

Hadfield, a Canadian Space Agency astronaut, is celebrating the Irish holiday in orbit by wearing a green shirt and a bright green bow tie today (March 17) while photographing Ireland from space.

"Maidin mhaith from the International Space Station! Happy Saint Patrick's Day to the Irish all around the globe. Good morning!" Hadfield wrote in one of several Irish-themed Twitter posts today. Maidin mhaith is Gaelic for "Good Morning."
