What If I Told You Rockets Just Don't Work In Space?

Why do you post idiotic folderol?

It's tiresome.

I would tell you you're an idiot, opie.

I'd say, you are an idiot.

Tell that to prehistoric backward NASA.

And I am taking this light speed invention to the grave.

Fuck TPTB

Would say you need to go back to school

You can't keep picking and choosing to promote your weirdo agenda. You discount almost everything else that enables rockets to work in space you dolt! Please learn basic physics and try again.

I'd say you just proved ignorance is everywhere.

The experament you need to try is sit in a wheeled chair with a large book in your hands and with your feet off the floor throw the book away from you and see if you don't roll in the opposite direction.

That's early elementary science when and where I grew up.

Really, let see ... what did NASA use in rockets ...

.. Prehistoric backward fire? ...

... must have oxygen in rockets to make fire work

You need to go back to Nursery School with the rest of NASA scientist

Are you serious?

I think if you have a vehicle it has to push against something. Cars push against the road, aeroplanes push against the air. There is nothing to push against in space so NASA would have to bring there own stuff with them to push against, I think.

Close.

Rockets work by forcefully expelling gas, which is created by burning liqud or solid fuels. So yes, nasa sorta brought their own.

The expelled gases push the rocket forward because of the 'equal and opposite reaction'. This force (expelled gas) acts upon the mass (the rocket) regardless, a reference mass (air, water, solids) is not required for this law to apply.

What if I told you that you're entitled to draw whichever conclusions you like, however stupid they are?

And you would be correct. It's called a nozzle.

Do you really think that baloon below will moves into space?

rocket thrust counter gravitational pull, momentum is then free fall. thrust loses potential in a lesser gravitational environment. the less gravitational pull the less effective rocket thrusters are comparitively. to say that rocket thrusters don't work in space is a big misunderstanding of the principals at work.

Idiots all in the UK it seems.

I know it will.

"What If I Told You Rockets Just Don't Work In Space?"

I'd say, go back to High school, or try for your GED.

Like a standard kilogram you mean?

Hey! don't forget Italy.

Cars don't push against their wheels, they push against the road.

"There are two ways to do this, first you can pack oxygen in the form of LOX or liquid oxygen. You then feed LOX with your fuel in the rocket engine and you have combustion. This can be difficult as LOX must remain under pressure, and can get very cold."

"The second and sneakier way is to carry chemically bound oxygen. This is a stable compound which has oxygen as part of its chemical formula. We call these chemicals "oxidants." Examples are Potassium Permanganate KMnO4, Hydrogen Peroxide H2O2, and Nitric Acid HNO3. When kept by themselves, they are fairly easy to handle. When mixed with other compounds, violent reactions can occur."

Always holds true.... Italians are imbeciles.

Meanwhile, in America....

@OP

A vacuum environment does not stop action/reaction from happening.

Only a tiny fraction of a rockets thrust is a result of pushing against the air, in fact that extra push is less than the friction incident upon the nose due to the air.

So a rocket is actually more efficient in space.

The bulk of the rockets thrust is just a result of throwing mass out the back at high speed.

The total integrated kinetic energy of the complete system (rocket and exhaust) remains zero, the rocket exhaust speeding one way, the rocket body the other.

An ion thruster uses this effect also, only it throws a tiny mass out at very high speed.

To understand it conceptually imagine you are in free space clinging onto an asteroid the size of a car. Now you stand up and jump as hard as you can, you would depart the asteroid and move in one direction, but the asteroid would start moving a little in the opposite direction.

Now imagine you are in space clucthing a fist sized rock, you throw it as hard as you can, the rock flies forward but you fly backward a little.

If the rock is the same mass as you then you both fly in opposite directions at equal velocities.

WORD!

Actually rockets maintain the speed that they left orbit in when they reach space although thrusters do not work in space... their needs to be a certain amount of gravity for thrusters to work.

Indeed, a parabolic nozzle ensure the exhausts last contact with the rocket is dead in line with the rockets body. Without the nozzle lots of radial force is generated which is cancelled and wasted.
