Collection Item Summary:

This is a single tread taken from the enormous crawler-transporter that carried the Saturn V moon rocket and, later on, the space transportation system, from the Vehicle Assembly Building (VAB) to one of the two launch pads (39A and 39B) at NASA's Kennedy Space Center (KSC), Florida. Each of the tank treads weighs two thousand pounds. The six-million-pound crawler has eight tracks, each of which measures 10 feet in height and 41 feet in length. Each track contains 57 treads.

NASA operated two crawlers at KSC during the Apollo and shuttle programs. Each crawler carried its cargo at a speed of only one mile per hour, covering a distance of 3.4 miles to launch pad 39A and 4.2 miles to pad 39B.

The Marion Power Shovel Company of Ohio began to develop the crawler in 1962. The first one entered service in 1966.

The NASA Kennedy Space Center transferred this to the Museum in 1972.
