t. e. Non-rocket spacelaunch refers to theoretical concepts for launch into space where much of the speed and altitude needed to achieve orbit is provided by a propulsion technique that is not subject to the limits of the rocket equation. [1] Although all space launches to date have been rockets, a number of alternatives to rockets have been ...
The vacuum-sealed centrifuge is able to spin a rocket at speeds of up to 4,700 mph (7,500 km/h; 2.1 km/s) before releasing it on a trajectory path headed towards low Earth orbit. Once the rocket reaches an altitude of roughly 200,000 ft (60 km), the rocket would then ignite its engines in order to reach an orbital speed of 17,150 mph (27,600 km ...
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.

The BE-3 is a family of rocket engines made by Blue Origin with two variants, the BE-3U and BE-3PM. The rocket engine is a liquid hydrogen/liquid oxygen (LH2/LOX) cryogenic engine that can produce 490 kN (110,000 lbf) and 710 kN (160,000 lbf) of thrust
During its pre-merger presentation, Rocket Lab predicted it could grow its revenue at a compound annual growth rate (CAGR) of 97% from $35 million in 2020 to $267 million in 2023. It ended up ...
