Physics of Propulsion: Learn About Space Travel Tech

[VyRianS]

Hey all, first time poster.

I have had a long-standing interest in astrophysics and space-related travel. I read a lot about such topics during my free time and from what I've read, only reaction mass (rocket) engines are currently possible for earth-to-space launches. This gets both inpractical and troublesome due to the exponential growth of reaction mass needed.

A new propulsion system that could circumvent such a limitation would be incredible. Space launches would be simpler and way cheaper (currently at $10,000 per pound).

Does anyone have good starting materials for a student to learn more about space propulsion (theories/mathematics... everything)?

2 types of propulsion used in space other than chemical rockets are ion propulsion and the hall effect propulsion. both are forms of ion propulsion. they offer more bang for the buck. but their is a drawback. they only produce a small amount of thrust, however they can run more than 100 times longer than chemical rockets on the same weight of fuel. deff something worth reading about.
