# NASA Apollo 11 fuel used to land on the moon [duplicate]

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?

• This is a (somewhat unintentional?) repost of the same question from yesterday. Considering the number of comments the OP posted there as accidental answers, it looks like you might benefit from slowing down a bit and familiarizing yourself with how to use the site. You can take the tour and also visit the help center to learn more.

• It's not a dupe. The previous question asked about insertion into lunar orbit, this one is asking about descent from lunar orbit to surface. Apr 12, 2019 at 0:32
• That said, @carleto, you may want to take a look at How do we know the Apollo Moon landings are real before going much further with this line. Apr 12, 2019 at 0:35

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.

• A15? 8873 kg of propellant loaded, plenty of margin. Apr 12, 2019 at 19:58
• 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. Apr 13, 2019 at 19:21
• 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. Apr 13, 2019 at 19:37
• How much fuel does it take to launch a 2,500 lb lay load into the earth's orbit? Apr 13, 2019 at 19:49
• That is not a BBC documentary @carleto
