The top of the Vehicle Assembly Building is seen from the tower of NASA's new mobile launcher or ML support structure.

At NASA's Kennedy Space Center in Florida, the top of the 525-foot-tall Vehicle Assembly Building, or VAB, is seen from the tower of NASA's new mobile launcher, or ML, support structure. It took about two years to construct the launcher in the Mobile Launcher Park site, north of the VAB.

The 355-foot-tall structure will support NASA's future human spaceflight program. The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket. The next step will be to add ground support equipment, such as umbilicals and access arms, for future rocket launches. For information on NASA's future plans, visit www.nasa.gov.
