NASA has posted a video message for St. Patrick’s Day from Expedition 27 Flight Engineer Catherine Coleman, who’s currently aboard the International Space Station.

Watch the video here below.

Coleman, who is part Irish, brought with her on her ISS mission several Irish flutes, courtesy of the Dublin-based group The Chieftains. In the video, she talks a little bit about the instruments and then plays them as she floats inside the space station.

The astronauts at the International Space Station celebrated the new year 240 miles above the Earth.

The crew recorded a special New Year’s message for all of us here on the planet, which you can watch here below. Each of the space men gave a personal greeting, including two crew members who did so floating upside down.

Space Shuttle Discovery is finishing up its final mission, a 13-day visit to the International Space Station. The ship will make its final landing at Kennedy Space Center in Florida on Friday after which it will be retired. For those of us who have grown up with Discovery, it’s a little sad to see it retire.

Each morning, a special song usually picked by their families awakens the astronauts on board. For this last mission NASA decided to hold an online contest to allow fans to pick the songs. Nearly 2.5 million votes were cast between August 20, 2010 and November 1, 2010 Alexander Courage‘s theme song to the original Star Trek television series was the second most popular song of the ones available getting 671,133 votes or 27.2% of the total votes.
