I thought about this a few days ago.
What changes an outer space vehicles direction and how?
What do thrust against?Thrust engines

So- a lack of gravity? Or, just against gravity?anti-gravity

I know they use "thrust"- I'm just wondering what they thrust against. Thrust propels using an/our atmosphere to push a mass someplace it wasn't. Right?
Newton's Third Law of Motion states: 'To every action there is an equal and opposite reaction'. ... The action and reaction are equal and opposite.What do thrust against?Thrust engines
Doesn't that apply just to gravitational forces?Newton's Third Law of Motion states:
Sit on a skateboard and throw a baseball, you will travel some small distance in the opposite direction. Same thing will happen on the moon or in space. The thrusters are sending masses of hot gas out their nozzles, just like you throwing a baseball.Doesn't that apply just to gravitational forces?Newton's Third Law of Motion states:
If not can we stop debating the "blow back" and realize what we're doing in the ME is a direct reaction to the action taken in 1953?
I digress- sorry.
If a thruster device thrusts against nothing how can it work?
If on a straight trajectory and a course correction is necessary- or, as the movies have depicted, turning the ass end to the surface of wherever, how does that happen?
I don't understand. I'll admit to not being formally educated but I have a pretty good grasp on energy, energy conversion, aeronautical lift, heat transfer etc,. but, like I said this is just a question that came to mind the other night and I was hoping someone here could could provide a layman's answer.
Thanks! I think- LOL that is a great example of "rocket science".
Not exactly.just like you throwing a baseball.
Essentially themselves. It's a physics thing. Every action has an equal and opposite reaction. This is why they call the fuel for thursters "reaction mass". The act of accelerating the reaction mass out of the thruster accelerates the spacecraft in the opposite direction.What do thrust against?Thrust engines

reading prior to posting helps one not look a fool-

When I started this thread I was a bit concerned with the use of the term "outer space" but decided to keep it as simple as a simple mind can put it.
The link explains a lot and outer space, as we believe(d) it to be, is not really a void of nothing-
Each "system" still uses thrust, for lack of a better word. The space we call outer has different than what we're acquainted with in terms of atmosphere, or gravity. I was aware of the orbiting explanation it cited which relies of gravity, but I was wondering about the rest of it. And now I know!
LOL- did I hurt your feelings, punk? Your lame reaction doesn't change a thing I said.Keep in mind I'm not the one who asked the question, kid.
No, my feelings aren't hurt. I tried to help and you insulted me.LOL- did I hurt your feelings, punk? Your lame reaction doesn't change a thing I said.Keep in mind I'm not the one who asked the question, kid.
It is thrusting against itself. You have lit a bottle rocket before, right?If a thruster device thrusts against nothing how can it work?
No, exactly. You hurl a mass in one direction, you move in the opposite direction.Not exactly.just like you throwing a baseball.
