See the red ball in the upper portion of the lander? That is the fuel used to escape the moons gravity.
The Apollo 11 rocket needed 260,000 pounds of fuel to get into earths orbit.
Apollo 11 used RP1 propellant which is more efficient than aerozine-50.
Aerozine 50 was used in the lander to escape the moons gravity.
The moons gravity is about 1/6 of the earth, the escape velocity needed is about 1/6 also.
So how much Aerozine-50 would have been needed to get the lander off of the moon?
I know the rocket is larger than the lander but it still seems to me that the lander has a VERY SMALL amount of fuel compared to the Apollo 11 rocket.
Also, seen as there is no oxygen in space, where is all the oxygen stored that is needed to burn the Aerozine-50???
