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?


1 Answer 1


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.

  • $\begingroup$ A15? 8873 kg of propellant loaded, plenty of margin. $\endgroup$ Apr 12, 2019 at 19:58
  • $\begingroup$ My calculations show the amount of fuel required to land on the surface of the moon using descent rocket is 250,000 lb using a lander moon wt of 2,500 lb yet the according to NASA the lander contains 18,000 kg of fuel. $\endgroup$

    $\begingroup$ Then there’s something quite wrong with your calculations. Since you haven’t told us anything about them, it’s impossible for us to tell you where you’ve gone wrong. $\endgroup$ Apr 13, 2019 at 19:37
