No, the van Allen radiation belts weren't deal breakers for the Apollo astronauts. They really did go to the Moon. Want weekly Vintage Space ? Don't forget to SUBSCRIBE! www.youtube.com/channel/UCw95T_TgbGHhTml4xZ9yIqg
And tell us why there are no jets of flame or exhaust under it. Do you honestly think it connected with the rocket orbiting earth at 4000 mph thru space for the return trip?
Two places where rocket motors can't functtion: under water and in a vacuum. All they had was compressed air and momentum. I don't think they've been to the moon/Levan.

Rockets can certainly work in a vacuum. Jet's cannot as they burn oxygen in the environment, but rockets mix both oxygen and fuel, both stored on board, to produce the thrust. In the vacuum of space, rockets are more efficient as there is no aerodynamic drag on the ship, which factors in favor of the lunar modules lift-off from the moon surface.

To be exact, not "compressed air" but compressed oxygen. Air is only about 20% oxygen, with most of it nitrogen. For space flight, they use pure oxygen, and the Apollo missions used oxygen so compressed it was a liquid, not a gas. And of course, it was more than oxygen but fuel as well.
I've seen tests. Rockets can barely fizzle in a vacuum before going out.
This is the first time I've heard of such a thing. Rocket engines simply need fuel and oxygen to function, both of which are stored on board. Liquid fueled rockets typically carry liquid oxygen & liquid hydrogen, or perhaps kerosene or similar. Both are continuously piped to the exhaust chamber where they will burn and generate thrust. Solid rockets, like the shuttle boosters, have the oxidant and fuel mixed together into a solid material which burns away smoothly. The entire inside of booster is the burn chamber.
In neither case is any air from outside of the rocket required, so they will work in a vacuum.
