How to create propulsion in space?

Question

Is Jet propulsion the only way to accelerate in space? Or can carbon dioxide be expelled and used to propell at any decent rate?

Answer 1

Jet propulsion is never used in space...

Jet propulsion requires atmosphere to work, and space is a pseudo-vacuum with negligible oxygen and free particle content.

CO2 is used sometimes in cold gas propulsion which is mainly used for satellite staionkeeping and pointing... It was also used on Apollo spacecraft for pointing and maneuvering...

Propulsion of any consequence is supplied by rockets, solid and liquid. These are chemically based.

Other space propulsion systems (both used and theoretical) include:

Electric propulsion (used on many satellites), nuclear thermal(test models built, never flown), nuclear-pulsed(theory), hybrid (solid-lquid, built and used) and many other systems either in development or in use.

Answer 2

Anything expelled will produce acceleration. The faster that it is expelled, the more acceleration for a given mass.

However there are other propulsion schemes involving Solar Sails which reflect sunlight for propulsion or magnetic propulsion using earths magnetic field, or laser propulsion either from the space craft itself or fired from earth and bounced off the space craft.

Answer 3

Any time you expell something, it will create propulsion in space. Ultimaltely, this comes from conservation of momentum, so the faster you can expell, the more force you get. Also, the more massive the stuff is that you expell, the more force you get,

Answer 4

Microwave propulsion already exists yet is only too risky ,demands top ability and desires a stable floor to artwork on.besides the shown fact that an identical propulsion called photograph voltaic-Sails exist the place an area craft/sattelite has a sail only like olden ships.This sail is a floor onto which the sunlight's radiation acts thereby pushing the craft.of direction,you may only flow faraway from the sunlight using this technologies. listed under are a number of my very own suggestions of a propulsion that propels by using area . the fabric of area behaves like the previous lumineferous aether.It ability that it conducts easy with 0-resistance.hence easy travels at a relentless velocity by using area without slowing down.to bypass in area using easy you may choose some thing to act against for circulation.in line with probability we would use the shown fact that area itself has resistance prefer to electric powered modern-day and magnetic fields (the two fields exist in easy).It additionally has resistance that forestalls shifting products to exceed the fee of sunshine.in line with probability we would use the fabric of area as a 'floor' to act upon for propulsion.in line with probability if if we forced EM waves previous the fee of sunshine,the waves does no longer bypass previous 3 hundred,000 km in line with 2nd however the greater power would be transferred to the fabric of area as a variety of stress.in this variety,severe power easy would act upon area itself for propulsion.

Answer 5

Gas turbine engines use the brayton cycle and are not used for space travel as there is a need for air to go into the combustor and be compressed.

Answer 6

dude

what ur talkin about is the era of horses and swords



get up to date with tech

Answer 7

gravitational pull is the best way but we are hundreds of years from that capability

Answer 8

Just stick your asre out the porthole and fart.
