Commander Chris Hadfield has been making the most of St Patrick's Day aboard the International Space Station but he has also had the ISS' cameras trained on Ireland today.

The Canadian astronaut tweeted these photos of Tralee:

He has also recorded his own version of 'Danny Boy' in orbit: 

Danny Boy strikes home with me, now more than ever. I've recorded a version for today in orbit. Hope you like it! soundcloud.com/colchrishadfie…
