I've been enjoying Astro_Mike's Twitter feed. Mike Massimino was one of the astronauts on the just-concluded shuttle mission.
A couple days ago he wrote:
"From orbit: Flying over the Pacific Ocean at night there were some thunder storms, it is so cool to see lightning go off below the clouds"
Hard not to be a little envious of an experience like that.
Here's a photo set of the mission from the always excellent Big Picture.
