RCS stands for "Reaction Control System"
The two types of RCS control are directional thrusters and reaction wheels
Directional thrusters are the most commonly used.
Did you learn about vectors in math?
Knowing basic vector calculations helps to visualize this
Reaction wheels are used to spin the spacecraft along the longer axis, while RCS thrusters are used to translate and rotate the spacecraft along the other axes
Ok. I got what you’re saying. In order to propel a heavy space vehicle in a vacuum requires an incredible force...especially as there is nothing to push against. Agreed?
Not an incredible force, just a force in general
The "nothing to push against" doesn't matter here, as the rocket engine is a self contained system. The fuel being ejected out the back is why the rocket moves forwards.
How much fuel is needed to lift off from earth, carry that craft to the moon (bearing the weight of a Land Rover, btw), landing successfully, taking off again and coming back to earth?
It depends on the type of fuel used, and the engines used in each stage
For example, Ion engines use Xenon gas, while conventional rockets tend to use kerosene, or a mixture of liquid hydrogen and liquid oxygen.
Certain boosters also use solid fuel, but those are mainly for support
So how much fuel is needed?
In this instance
It depends on the kind of fuel. What mission do you want to analyze?
The engine efficiencies matter as well
First moon landing
There's a reason people say "this isn't rocket science"
It's complex stuff
And even the tiniest change can throw off everything. Case in point, the Challenger Shuttle disaster. The entire shuttle blew up because a singular rubber ring cracked, because it was slightly too cold that morning.
My friend posted this I’m no longer friends with them

Shoot, what did he say, I didn’t get to see it?
He claimed to be s flat earther
Oh, that’s it? Eh
Then posts shit like that
He’s a troll
Oh, nvm, lol
In total, for the Saturn V rocket
That’s not what I asked gohan
