Purpose edit

The Lunar Bus Group is in charge of transport the Lunar Lander and the Rover to the Moon Orbit.

Overview edit

The following section is based on some forum posts.


Decent thrusters serve to hold the top of the Arrow up while the bottom hangs down by inertia & gravity. Decent thrusters act like a parachute and don’t have any control action except to push against the Arrow’s inertia and the moon’s gravity.

Three ideas for decent thrusters:

1 – At least 3 liquid engines at the top of the Arrow blowing down and to the side. May possibly be modulated or controlled by altitude.
2 – Bunches of smallish solid rockets at the top that fire down and to the side in balanced gangs. Firing is sequenced by altitude.
3 – A single liquid rocket held above the top of the Arrow that thrusts down and directly at the top of the Arrow similar to the Apollo capsule emergency escape tower that was to lift the capsule away from the launch pad in the event of a launch disaster prior to or during the Saturn V liftoff. This could be modulated via altitude.
4 – Solid fuel version of item 3 above.

Work needed:
For Items 3 & 4 above: Sort out the relationship between length of “escape” tower and materials protection given that the rocket blast will be right onto the top of the Arrow. I am only guessing but I suspect liquid rockets are less dirty than solid fuel.
