Sir Elton John has sent a special message to the astronauts making NASA's last shuttle flight.
In honour of the event, NASA beamed up a pre-recorded message by the British singer, as well as a half-minute clip of his 1972 song Rocket Man.
"Good morning, Atlantis, this is Elton John," the star said.
"We wish you much success on your mission and a huge thank you to all the men and women at NASA who worked on the shuttle for the last three decades."
"Elton John. Music legend. Wow. That is absolutely fantastic," Atlantis' commander Christopher Ferguson said.
"I think it just illustrates ... the amount of people globally who have been affected by the shuttle program itself."
Rocket Man has awakened previous shuttle crews and was on NASA's top 40 list of wake-up music for public voting earlier this year.
