The astronauts taking part in NASA's last space shuttle flight have received best wishes from the original 'Rocket Man'.
Elton John's special message was beamed up by NASA - as well as part of his song which was inspired by space exploration.
All four shuttle astronauts gathered for the wake-up song - and were joined by the six residents of the International Space Station.
Sir Elton said: "Good morning, Atlantis, this is Elton John. 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."
Atlantis' commander, Christopher Ferguson replied: "Elton John. Music legend. Wow. That is absolutely fantastic".
Rocket Man was on Nasa's Top 40 list of wake-up music for public voting earlier this year.
It won more than 4,300 votes for 17th place.
