This video was taken on 17 April 2009 at Camp 2 on Mount Everest at 21,500 feet. In it, IMG climber Scott Parazynski talks live via satellite phone Michael Barratt aboard the International Space Station on the occasion of his 50th birthday. In the background are three sherpas - the middle one, Danuru, will accompany Scott to the summit. Together they are known as the "Singing Sherpas". Video courtesy of Ed Wardel.
