I discovered his Twitter feed about three months ago. Many times each day Commander Hadfield would share comments about his daily routine and tasks, but also he would post spectacular photographs taken from the ISS as it orbited the earth. His twitter feed can be found here. Here are a few of his images,I just love seeing how amazing the Earth looks from space!
Finally, before returning to Earth this recording of Space Oddity was posted to You Tube.
I'd just like to say to Commander Hadfield, thanks for keeping us all in touch with things on the ISS and I loved looking at the amazing images of Earth every evening. Hopefully a new crew member will carry on this work!
