Northrop ALSS Rover

American manned lunar rover. Study 1964. Northrop completed Molab Studies under a Apollo Logistic Support Systems contract in March 1964.

Alternate cabin designs were considered, but all had an internal chassis and a range of 400 km with a crew of 2 on a 14 day traverse.

Variants of the standard design were:

  • M-1. Front-end airlock. Horizontal cylindrical cabin. 3010 kg, cabin volume 11.33 cubic meters.
  • M-2. Right circular cylinder, vertical cylindrical cabin. Rear end air lock. 2900 kg, cabin volume 11.33 cubic meters.
  • M-3. Horizontal cylindrical cabin. Rear end airlock. 2860 kg, cabin volume 8.5 cubic meters.
  • M-4. Horizontal truncated cylinder. Rear end airlock. 2570 kg, cabin volume 6.51 cubic meters.
  • M-5. Horizontal cylindrical cabin. Rear end airlock. 3170 kg, cabin volume 8.50 cubic meters. Considered best concept of the five.


Crew Size: 2.

Gross mass: 3,170 kg (6,980 lb).
