Beyonce gave the crew of NASA's space shuttle Atlantis a surprise wake-up call Monday (July 18), when she delivered a special message to the astronauts, to prepare them for their 10th day aboard the shuttle.

With her new single 'Run the World (Girls)' playing in the background, the pop star offered the crew of four her gratitude, as well as some words of inspiration.

"Good morning Atlantis. This is Beyonce," the pre-recorded message began. "Sandy, Chris, Doug and Rex, you inspire all of us to dare to live our dreams -- to know that we're smart enough and strong enough to achieve this. This song is especially for my girl Sandy and all the women who've taken us to space with them, and the girls who are our future explorers."

Sandy Magnus, the lone female aboard the shuttle, happily responded to the singer, saying, "Good morning, Houston. A big thanks to Beyonce for taking the time out of her schedule to record us a greeting, and we're ready for another day here on Atlantis."

Atlantis lifted off on July 8, on the shuttle program's final flight, STS-135, a 12-day mission to the International Space Station, with a multipurpose logistics module containing supplies and parts for the space station.

Beyonce's new album '4' is in stores now.
