Apollo W-1

Apollo W1

American manned spacecraft. Study 1962. Martin's W-1 design for the Apollo spacecraft was an alternative to the preferred L-2C configuration. The 2652 kg command module was a blunt cone lifting body re-entry vehicle, 3.45 m in diameter, 3.61 m long.

The propulsion, equipment, and mission modules were identical with those proposed for the L-2C baseline. The RV shape was heavier than the W-1 but provided higher maneuverability (hypersonic L/D ratio of 0.75). Flaps and a parachute landing system being used for final recovery were used as in the L-2C. The circumlunar version had a total length of 11.4 m including a short launch escape tower and a fuelled mass of 6,677 kg.

A single crewmen was seated in the forward part of the vehicle, with the other two behind, in couches that rotated 90 degrees from launch to re-entry positions. A jettisonable mission module (not used on the circumlunar version) could also serve as a solar storm cellar, a laboratory, or even the descent stage of a lunar lander.

Gross mass: 6,677 kg (14,720 lb).
Height: 11.40 m (37.40 ft).

  • Saturn V American orbital launch vehicle. America's booster for the Apollo manned lunar landing. The design was frozen before a landing mode was selected; the Saturn V could be used for either Earth-Orbit-Rendezvous or Lunar-Orbit-Rendezvous methods. The vehicle ended up with the same payload capability as the 'too large' Nova. The basic diameter was dictated by the ceiling height at the Michoud factory selected for first stage manufacture.
