A launch loop or Lofstrom loop is a published design for an active structure maglev cable transport system intended for orbital launch that would be around 2,000 km (1,240 mi) long and maintained at an altitude of up to 80 km (50 mi). A launch loop would be held up at this altitude by momentum of the belt as it circulates around the structure. This circulation, in effect, transfers the weight of the structure onto a pair of magnetic bearings, one at each end, which support it.

Launch loops are intended to achieve non-rocket spacelaunch of vehicles weighing 5 metric tons by electromagnetically accelerating them so that they are projected into Earth Orbit or even beyond. This would be achieved by the flat part of the cable which forms an acceleration track above the atmosphere.[1]
The system is designed to be suitable for launching humans for Space tourism, Space exploration and Space colonization, and provides a relatively low 3g acceleration.[2]
