The amount of fuel required to launch a spacecraft from the Moon depends on several factors, including the mass of the spacecraft, the desired trajectory, and the propulsion system used. However, I can provide you with a rough estimate based on historical missions.
During the Apollo lunar missions conducted by NASA in the 1960s and 1970s, the Lunar Module (LM) was used to transport astronauts from the lunar surface back to the Command Module (CM) in lunar orbit. The ascent stage of the LM, which carried the astronauts, used a rocket engine called the Ascent Propulsion System (APS).
The APS on the Apollo Lunar Module consumed approximately 2,750 kilograms (6,060 pounds) of a mixed propellant consisting of Aerozine 50 (fuel) and nitrogen tetroxide (oxidizer). This propellant combination is known as Aerozine 50/N2O4.
It's important to note that the LM ascent stage was not launched directly from the Moon's surface into Earth's orbit. After the ascent stage rendezvoused with the CM, the entire spacecraft (CM and LM) performed a trans-Earth injection burn to leave lunar orbit and return to Earth.
If you're specifically interested in the fuel required to launch a spacecraft from the Moon's surface into lunar orbit, the estimate mentioned above can give you a general idea. However, the exact requirements will vary depending on the specific mission parameters and spacecraft design.
