Space shuttle Endeavour commander Mark Kelly delivered an out-of-this-world message to a U2 concert after Bono dedicated the song "Beautiful Day" to Kelly's wife, Arizona Rep. Gabrielle Giffords.

Bono told the crowd at Seattle's Qwest Field on Saturday night, "Imagine a man looking down on us from 200 miles up. Looking down at our beautiful crowded planet. What would he say to us? What is on your mind Commander Kelly?"

Kelly then appeared on a video board from the International Space Station and quoted lyrics from David Bowie's `Space Oddity.' "Tell my wife I love her very much," he told the surprised crowd.

NASA says Kelly recorded the message during the recent 16-day mission to the space station. Endeavour returned to Earth on Wednesday.
