Bipropellant rocket engines of the Apollo Lunar Module reaction control system (RCS) Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.
In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth, an orbital maneuver is called a deep-space maneuver (DSM). [1] When a spacecraft is not conducting a maneuver, especially in a transfer orbit, it is said to be coasting.
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
Armadillo Aerospace's quad rocket vehicle showing shock diamonds in the exhaust plume from its propulsion system. Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid.

High hopes aside, SpaceX has been known to embrace fiery mishaps and explosions in the early stages of developing a new rocket. SpaceX has said its approach to rocket development is geared toward ...
Initially scheduled to launch on Wednesday, SpaceX is now targeting Thursday due to weather, the company shared on X, the social media platform formerly known as Twitter that Musk purchased in 2022.
It is possible that such beam-powered propulsion could be useful for long-duration high altitude uncrewed aircraft or balloons, perhaps designed to serve – like satellites do today – as communication relays, science platforms, or surveillance platforms. A "laser broom" has been proposed to sweep space debris from Earth orbit. This is ...
SpaceX's Falcon Heavy rocket, currently the most powerful launch system on Earth, roared into the sky on Tuesday afternoon atop a pillar of smoke.
