An Apollo Meme is a joke, not the one its author intended

 This has been shared over 250 times on Facebook - that was some months ago and I'm not counting again. 

Let's start with the image - it couldn't have been taken in space, as all the Apollo astronauts were inside the spacecraft when the Command and Service Module was docked with the Lunar Module in lunar orbit.  So it must be a model, and so it is, from the LEGO IDEAS site.

But what about the "one tank of gas and oxygen"?  First, let's give the memester some credit for not asking how Apollo burned fuel in the vacuum of space.  The various engines and reaction control systems used oxidizers, either liquid oxygen or nitrogen tetroxide.  And how much fuel did the mission carry?  See this video for more information than you thought you were asking for

As usual, this meme shows that while flat-earthers tell you to engage in research, that's something they don't do themselves
