The Universe

[Stupie82]

Only as much as to escape our atmosphere, as said before once in space there's 0 gravity so with conservation of energy the spacecraft is essentially using no fuel from around 100 miles up. There is a very small supply of fuel in the landing module used to fire up a reverse thrust to slow the craft down on final descent to the lunar surface, and also to provide literally a few seconds thrust to escape the lunar atmosphere on returning to earth. (Remember the lunar atmosphere and gravity is about one sixth of that on earth, coupled with the fact the mass of the  landing module is tiny compared to that of the launch rocket at take off from Cape Canaveral, where some of the fuel initially used is in effect used to carry the fuel required to escape our atmosphere).

 

Exactly just what i was away to write!    Well said!!

 

Here are some images I took from Cape Canaveral in 2009 and Johnson Space Center 2014
