A multistage rocket or step rocket [1] is a launch vehicle that uses two or more rocket stages, each of which contains its own engines and propellant. A tandem or serial stage is mounted on top of another stage; a parallel stage is attached alongside another stage.
Space launch involves liftoff, when a rocket or other space launch vehicle leaves the ground, floating ship or midair aircraft at the start of a flight. Liftoff is of two main types: rocket launch (the current conventional method), and non-rocket spacelaunch (where other forms of propulsion are employed, including airbreathing jet engines).
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
Airlines face a growing headache over rocket launches after Starship's fiery liftoff last week. ... "SpaceX had a rocket launch and, uh, it didn't go so well," an air-traffic controller said in an ...
Rockets were used to propel a line to a stricken ship so that a Breeches buoy can be used to rescue those on board. Rockets are also used to launch emergency flares. Some crewed rockets, notably the Saturn V [46] and Soyuz, [47] have launch escape systems. This is a small, usually solid rocket that is capable of pulling the crewed capsule away ...
Amazon founder Jeff Bezos's space company has blasted its first rocket into orbit in a bid to challenge the dominance of Elon Musk's SpaceX. The New Glenn rocket launched from Cape Canaveral Space ...
All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The ...
Jeff Bezos’ rocket company Blue Origin is cutting 10% of its workforce. This week's move comes a month after the debut of Blue Origin’s New Glenn rocket, which reached orbit on its first try.
