Crawler-Transporter Passes Milestone Test at NASA's
Kennedy Space Center
The crawler-transporter that will carry NASA’s Space Launch System (SLS) and
Orion spacecraft to Launch Pad 39B for launch on Exploration Mission-1 in 2017
recently passed the first phase of an important milestone test at Kennedy Space
Center in Florida. The Ground Systems Development and Operations Program
completed testing of new traction roller bearings on crawler-transporter 2
(CT-2), on two of the massive vehicle’s truck sections, A and C, in late
January. The new roller bearing assemblies that were installed on one side of
the crawler are visible in this Jan. 31, 2014 image. CT-2 returned to the
Vehicle Assembly Building (VAB) at Kennedy Space Center, where work continues to
install new roller bearing assemblies on the B and D truck sections.
For more than 45 years the crawler-transporters were used to transport the
mobile launcher platform and the Apollo-Saturn V rockets and, later, space
shuttles to Launch Pads 39A and B. Upgrades to CT-2 are necessary in order to
increase the lifted-load capacity from 12 million to 18 million pounds to
support the weight of the mobile launcher and future launch vehicles, including
the SLS and Orion.
