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.
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.
Sub-orbital space flights, being at a much lower speed, do not generate anywhere near as much [further explanation needed] heat upon re-entry. Even if the orbiting objects are expendable, most [quantify] space authorities [example needed] are pushing toward controlled re-entries to minimize hazard to lives and property on the planet.

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.
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 ...
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.
The two-stage Super Heavy-Starship, known collectively as the Starship, is the largest, most powerful rocket in the world with twice the liftoff thrust of NASA's legendary Saturn 5 and nearly ...
A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.
