The tower on a new mobile launcher for the Constellation Program continues to grow as the sixth tower segment is balanced in position.

At NASA's Kennedy Space Center in Florida, the tower on a new mobile launcher, or ML, for the Constellation Program continues to grow as the sixth tower segment is balanced in position.

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.
