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.
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 end result is a layer of foam insulation 3.0 cm (1.2 in) thick on the LH 2 tank, with certain areas covered by up to 5.1 cm (2.0 in) of insulation. [ 25 ] Spray-on insulation is also applied to two of the dry elements, the intertank and the forward skirt.
Block 1 variant of SLS rocket SLS with the Orion capsule stacked in the Vehicle Assembly Building, March 2022. SLS/Orion is assembled by stacking its major sub-assemblies atop a mobile launcher platform inside the NASA Vehicle Assembly Building (VAB). First, the seven components of each of the two boosters are stacked.
Months before a launch, the three stages of the Saturn V launch vehicle and the components of the Apollo spacecraft were brought inside the Vehicle Assembly Building (VAB) and assembled, in one of four bays, into a 363-foot (111 m)-tall space vehicle on one of three Mobile Launchers (ML).
English: The enormous Vehicle Assembly Building at Kennedy Space Center, and the Launch Umbilical Towers seen here were constructed by NASA for one purpose… to build and launch moonships. In this January 1966 image (restored today from a faded 4"x5" NASA transparency) these structures are brand new, and launch tower #1 is being moved by a ...
The crawlers traveled along the 5.5 and 6.8 km (3.4 and 4.2 mi) Crawlerways, to LC-39A and LC-39B, respectively, at a maximum speed of 1.6 kilometers per hour (1 mph) loaded, or 3.2 km/h (2 mph) unloaded. [8] [11] The average trip time from the VAB along the Crawlerway to Launch Complex 39 is about five hours. [1]
In the time frame from 1969 to 1971 the cost of launching a Saturn V Apollo mission was between $185,000,000 to $189,000,000, [1] [2] of which $110 million were used for the production of the vehicle [68] (equivalent to $1.18 billion–$1.2 billion in 2023).
