At NASA's Kennedy Space Center in Florida, crawler-transporter No. 2 has been undergoing modifications inside high bay 2 of the Vehicle Assembly Building in preparation to carry the space agency's Space Launch System heavy-lift rocket to the launch pad.
NASA's Ground Systems Development and Operations Program is leading the 20-year life-extension project for the crawler. A pair of behemoth machines called crawler-transporters has carried the load of taking rockets and spacecraft to the launch pad for more than 40 years at NASA’s Kennedy Space Center in Florida. Each the size of a baseball infield and powered by locomotive and large electrical power generator engines, the crawler-transporters will stand ready to keep up the work for the next generation of launch vehicles projects to lift astronauts into space.
