To land on the surface of the moon required the lander to descent onto the lunar surface. How much rocket fuel was used to descend to the surface of the moon?
According to Apollo By The Numbers, the LM descent stage for Apollo 11 started with 8248 kg of propellant (fuel + oxidizer), and consumed 7899 kg of it in descent. 3050 kg of that was Aerozine-50 fuel, the rest nitrogen tetroxide oxidizer.
Additional equipment was added to later Apollo missions, so the LMs tended to get progressively heavier, and so used more fuel on descent; Apollo 15 used the most, at 8334 kg of 8873 kg loaded.
