The crawler transporter is a very large, heavy duty tracked vehicle used at the Kennedy Space Center (KSC) to move launch vehicles from the Vehicle Assembly Building to the launch pads.

• Originally designed and used for the original Apollo missions, two crawler transporters (CT) are now used by NASA to carry the Space Shuttle vehicles. 

• The CT’s weigh six million pounds each and are designed to carry a twelve million pound payload.

• Traveling at one mph, the CT’s are driven by electric motors powered by diesel engines.  The engines consume one gallon of fuel every fifty feet of travel. 

• Including the Apollo years, the transporters have racked up 2,526 miles, about the same distance as a one-way trip from KSC to Los Angeles by interstate highway or a round trip between KSC and New York City.
