I can’t embed the video as Picture Of The Day, but I enjoyed this piece on astronaut Chris Hadfield from the Australian version of “60 Minutes.” Hadfield is the one who became world-famous for his videos in space, including his version of David Bowie’s “Space Oddity.” He’s both a great teacher and spokesman for human exploration of space, and I’m looking forward to reading his book, “An Astronaut’s Guide To Live On Earth.”

One note: on the TV show, the reporter says Hadfield remembers watching Neil Armstrong and Buzz Aldrin step onto the moon’s surface on July 21, 1969. While that was the date in Australia because of the time zone difference, Hadfield and all the rest of us in North America watched that historic moment late on the night of July 20, 1969.
