The seventh tower segment being constructed to support the Constellation Program is hoisted by crane toward the six segments secured to the launcher's surface.

At NASA's Kennedy Space Center in Florida, the seventh tower segment of a new mobile launcher, or ML, being constructed to support the Constellation Program, is hoisted by crane toward the six segments already secured to the launcher's surface.

When completed, the tower will be approximately 345 feet tall and have multiple platforms for personnel access. The construction is under way at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I rocket, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit. 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 taller rocket.
