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.

  • $\begingroup$ A15? 8873 kg of propellant loaded, plenty of margin. $\endgroup$ – Russell Borogove Apr 12 '19 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. $\endgroup$ – carl eto Apr 13 '19 at 19:21

    $\begingroup$ 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. $\endgroup$ – Russell Borogove Apr 13 '19 at 19:37
  • $\begingroup$ How much fuel does it take to launch a 2,500 lb lay load into the earth's orbit? $\endgroup$ – carl eto Apr 13 '19 at 19:49

    $\begingroup$ That is not a BBC documentary @carleto $\endgroup$ – user20636 Apr 14 '19 at 23:35
