The Mobile Launcher Platform-1 on top of a crawler-transporter. A mobile launcher platform (MLP), also known as mobile launch platform, is a structure used to support a large multistage space vehicle which is assembled (stacked) vertically in an integration facility (e.g. the Vehicle Assembly Building) and then transported by a crawler-transporter (CT) to a launch pad.
The crawler-transporters have featured in television and movies. In a 2007 season three episode of Dirty Jobs, host Mike Rowe helps workers maintain a crawler-transporter and takes the vehicle for a short drive. [18] The crawler was also seen in the 1995 film Apollo 13, the 2011 film Transformers: Dark of the Moon and the 2019 film Apollo 11.
The Crawlerway was originally designed to support the weight of the Saturn V rocket and its payload, plus the Launch Umbilical Tower and mobile launcher platform, atop a crawler-transporter during the Apollo program. It was also used from 1981 to 2011 to transport the lighter Space Shuttles to their launch pads.
The crawler-transporter carried the mobile launcher platform and the Space Shuttle from the Vehicle Assembly Building (VAB) to Launch Complex 39, originally built for Project Apollo. The Shuttle Carrier Aircraft (SCA) were two modified Boeing 747s .

Each crawler weighed 6,000,000 pounds (2,720 t) and was capable of keeping the space vehicle and its launcher platform level while negotiating the 5 percent grade to the pad. At the pad, the ML was placed on six steel pedestals, plus four additional extensible columns. [21]
Space Shuttle Discovery is carried by a Crawler-transporter, a launch tower is visible in the background. A service structure is a steel framework or tower that is built on a rocket launch pad to facilitate assembly and servicing. An umbilical tower also usually includes an elevator which allows maintenance and crew access. Immediately before ...
The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA.
