Once at the launch site, final assembly of ML2 will begin, which will provide stability, power, coolant, fuel and communications to the spacecraft. The 380-foot-tall launcher will need to interface with the Vehicle Assembly Building and be constructed floor-to-floor, which will require an LR 11350 crawler crane. This massive crane, which has a maximum lifting capacity of 1,350 tons, will be responsible for lifting the modules and e-rooms for assembly. Once ML2 is assembled, and with the help of the hydraulic jacking system, it will need to be placed on the launch pad located at NASA’s Launch Complex 39B at Kennedy Space Center.
