NASA spacecraft Atlantis is gearing up for the scheduled July 8 launch to the International Space Station.

The STS-135 crew members climbed aboard the space shuttle on Friday for the countdown dress rehearsal.

The space shuttle Atlantis will carry a crew of four: Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandy Magnus and Rex Walheim.

As part of the Terminal Countdown Demonstration Test (TCDT), the astronauts are driven to Kennedy's Launch Pad 39A and then are strapped into space shuttle Atlantis to practice the steps that will be taken on the launch day a couple of weeks from now.

Similar to the launch day, the four astronauts put on their bright orange launch-and-entry suits and traveled to Launch Pad 39A at NASA's Kennedy Space Center in Florida aboard the Astrovan. The crew climbed into the space shuttle Atlantis and participated in a countdown dress rehearsal.
