I have my doubt also.
The escape velocity of the earth is 11.2km/s
The escape velocity of the moon is 2.4km/s
Where is the fuel kept in the video linked to below? I know a basic way to look at it and that it is going into orbit not escaping the gravity completely but to put a small satellite into earth orbit takes A LOT of fuel. Even if only 1/10th were needed on the moon due to no atmosphere and less gravity it does not seem like the ship they occupy is big enough to carry the fuel. Also why no visible exhaust, flames, fumes, smoke?
Am sure someone far smarter than me can explain it, honestly would love to know.
