LORL

Three-armed LORL is shown in this artist’s sketch. Center hub, which contains parking area for several space ferries, does not rotate and thus remains weightless. Under the parking area is a laboratory for study of weightlessness. The three arms rotate around the hub to create artificial gravity. Cutaway of one arm shows it to contain a series of rooms for other laboratory requirements and studies.
