Apollo Application Program: BALLOS
Concept art of BALLOS (BALlistic LOgistic Spacecraft), an Apollo-derived logistics spacecraft. It was studied by NASA, Lockheed and McDonnell-Douglas for the transportation of Astronauts to and from the Large Orbiting Research Laboratory (LORL) space station for the Apollo Application Program.
It came in three variants, a 6 astronaut version (2 crew, 4 passengers), 9 astronaut version (2 crew, 7 passengers) and a 2 astronaut version (2 crew, 10 passengers).
It would potentially be launched onboard either the Saturn IB or Titan III-C (in hammerhead configuration). The Saturn IB was preferred. Despite being bigger than the base line Apollo CSM, it would weigh roughly the same.
The 12 astronaut version has the following description:
"It is conical in shape with a spherical segment base. The base diameter of the spacecraft is 190 inches. The cargo-maneuver module is conical in shape and located immediately aft of the crew module. The conical shape adapts the 190-in. diameter crew module to the 260-inches diameter of the launch vehicle. This module is capable of carrying 13,455 lb of packaged cargo and 3,755 lb of maneuver propellant. This propellant is sufficient to meet the maneuvering impulsive velocity requirements of 1,050 fps which is provided by a modified LEM descent engine located in the module. Three solid-propellant retrorockets are located at the fore end of this module also.
This vehicle fulfills the mission requirements of delivering 12 men and 13, 455 lb of packaged cargo to a space station orbiting at an altitude of 260 nmi and an inclination of 29.5°. The launch vehicle puts the spacecraft in a 105 nmi parking orbit from which a Hohmann transfer is used to reach the rendezvous altitude of 260 nmi. Impulse for the Hohmann transfer and injection into final orbit is provided for in the 1,050 fps of impulsive velocity capability of the maneuver propulsion system. The maximum dynamic pressure of 525 psf is reached approximately 85 sec after launch. The maximum longitudinal acceleration during launch is approximately 4 g's."
At the end of the mission, the capsule would return to Earth for recovery, refurbishment and reuse. The propulsion module would be allowed to burn up.
"On an operational basis, prelaunch preparation time for a new [Ballos] spacecraft is 40 days. This time period includes receiving and shop processing prior to mating to the erected launch vehicle.
The projected 1968 to 1970 time period estimate for on-pad preparation time for the Saturn IB launch vehicle is 48 days. Of this, 23 days are allowed for payload mating and integrated vehicle checkout. The total prelaunch processing time required for the [BALLOS] vehicle, therefore, would be 63 days."
BALLOS never progressed past the study phase, like many proposals of the Apollo Application Program.
