The mobile launcher platform that was turned over from the shuttle program to the Constellation Program is being moved underneath.

At NASA's Kennedy Space Center in Florida, the mobile launcher platform that was turned over from the shuttle program to the Constellation Program last month is being moved from Kennedy's Launch Pad 39B via the crawler-transporter underneath. At left is seen the payload changeout room in the open rotating service structure. The platform will be rolled into the Vehicle Assembly Building's High Bay 3 in preparation for the Ares I-X flight test this summer. Ares I-X is the test vehicle for the Ares I, which is part of the Constellation Program to return men to the moon and beyond. Ground Control System hardware was installed in MLP-1 in December 2008. The platform was moved to the launch pad to check out the installed hardware with the Launch Control Center Firing Room 1 equipment, using the actual circuits that will be used when the fully stacked Ares I-X vehicle is rolled out later this year for launch.
