At NASA's Kennedy Space Center in Florida shows a new mobile launcher for the Constellation Program under construction.

At NASA's Kennedy Space Center in Florida, this aerial view of the mobile launcher park site area north of the 525-foot-tall Vehicle Assembly Building shows a new mobile launcher, or ML, for the Constellation Program under construction. In the background are the Atlantic Ocean and the Launch Complex 39 Observation Gantry, at upper right.

When completed, the tower will be approximately 345 feet tall and have multiple platforms for personnel access. Its base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket.
