there are aircrat that can fly higher, but they have to fly faster to get lift

i mean like military jets

yeah

if a rocket couldnt work in a vacuum wouldnt the jets not work

Jet engines require a medium to run, dont they?

There is a key difference between a rocket and a jet. A rocket doesn't use lift to fly. So an airplane can't work in a vacuum since nothing to push the wings up. A rocket ejects super heated gas backwards, which then push it forward

Also, while not extremely important. A jet engine uses oxygen from the air, while rockets have their own oxygen internally

That last part is key. Rockets bring their own oxygen, while airplanes get it from the air they move through.

that is just fuel of the engines, not how they propel things through the air/stay up

Rockets use pure thrust

yes, and jets use the differnce of air pressure under and over the wing to stay up

Yes

my point, rockets use thrust, while jets use difference in air pressure. thus you can say just because a jet doesnt work in a vacuum doesnt mean a rocket works in a vacuum

Oh thats not what I'm saying

I was thinking that a jet would work in a vacuum

but i guess not?

Idk

Eventually it would not have enough oxygen for injection so no

some very basics behind each

Sorry I was referring to a jet engine, not the whole jet.

just not enough stuff to push off of in a vacuum

rockets basically don't work in a vacuum

Why not there's nothing that stopping it

rockets use atmosphere to push off of

No

They don't

throwing gas into nothingness does nothing

Propellers use that

Rocket's are different from propellers

There's a difference between thrust and lift

rockets use propellent in the form of gas thrown out the back end to move forward

ignited gas

this prepellent needs an atmosphere to work to push off of something

otherwise its got no thrust

There's liquid and solid fuel as well

doesn't matter what type of fuel it is

its still propellant that propels the ship forward, and works well in an atmosphere

we can see it working

The amount of thrust can differ based on fuel
