According to wikipedia, a Jet engine is a reaction engine that discharges a fast moving jet of fluid to generate thrust by jet propulsion and in accordance with Newton's laws of motion. A rocket engine is a jet engine that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law.<br /><br />Thus, the primary difference is that the Jet engine carries only its fuel and takes in a air (oxygen) before combustion, while the Rocket Engine carries both fuel and oxygen (or combustible material).<br /><br />For space exploration, the better option is undoubtedly the Rocket Engine. This is because most of space is a vacuum and there would be no oxygen for combustion.

1. the major difference is that rocket engine carries its own supply of oxygen for combustion while jet engine requires oxygen from the atmosphere for combustion and cannot operate in the vaccum of space 2. Rocket engine is best suited for space exploration because of the reason stated above.

a jet engine sucks oxygen from the atmosphere and combust it with fuel carried in a tank whereas a rocket engine carries both oxygen and fuel in a special tank,thus jet engines can only  be use inside the earth's atmosphere but rocket engines can be use even out of the atmosphere because of the oxygen they carry.so rocket engine is the best to use for such purpose since it can work even in the vaccum(airless zone) outside the atmosphere.

A jet engine sucks oxygen from air and combust it with fuel carried in a tank While a rocket engine carries both fuel and oxygen in seperate supply tanks and does not require any external oxygen source. Hence rocket engines is suitable for space exploration.

A jet engine is an engine that obtains thrust by taking in air at the front, using it to burn fuel, then ejecting the hot combustion products at the rear through a propulsive nozzle; any engine propelled by expelling a high speed fluid jet (jet propulsion), such as a turbojet, turbofan, ramjet etc while a rocket engine is an engine that contains<br />both fuel and oxidizer and that<br />therefore can be operated in the<br />absence of air. Hence the major difference is the ability of rocket engine to operate in the absence of air while jet engine cannot. <br />And for exploration rocket engine is better because Jet engines need oxygen that<br />is pulled from the air outside<br />the aircraft and into the<br />engine to be mixed with fuel<br />and ignited for propulsion while<br />Rocket engines will either use<br />fuel that already contains<br />oxygen in it (such as<br />hydrazine) or pulls in oxygen<br />that is stored onboard the<br />air/spacecraft separate from<br />the fuel.

Well, to start with, a rocket creates thrust by expelling combusted fuel out the back of an opening in the tank or fuel container. The thrust is created by the chemical reaction you might call an explosion. A jet engine uses fans and multiple levels of chambers to compress air which it sucks in the front and blows out the back with greater force.
