Common Tools in Industry

Rocket Engines. A rocket engine is a type of propulsion system used for spacecraft, providing thrust to a vehicle by expelling hot gases from a combustion chamber. (e. g. Falcon 9)
Ion Thrusters. An ion thruster is a form of electric propulsion used for spacecraft propulsion, providing thrust by accelerating ions with electricity. (e. g. Dawn spacecraft)
Nuclear Thermal Rockets. A nuclear thermal rocket uses a nuclear reactor to heat a propellant, typically liquid hydrogen, to very high temperatures and then expel it through a nozzle to create thrust. (e. g. NERVA rocket)
Solar Sails. A solar sail uses sunlight pressure to push a spacecraft forward, allowing it to accelerate over time without the need for fuel. (e. g. LightSail 2)
Chemical Rockets. A chemical rocket utilizes a chemical reaction to generate thrust, typically burning a fuel with an oxidizer to generate hot exhaust gases that are expelled through a nozzle to create thrust. (e. g. Atlas V rocket)
