The first rockets were used as propulsion systems for arrows, and may have appeared as early as the 10th century in Song dynasty China. However, more solid documentary evidence does not appear until the 13th century. The technology probably spread across Eurasia in the wake of the Mongol invasions of the mid-13th century.
2018 - The Electron rocket was the first New Zealand rocket to achieve orbit. The rocket is also unique in using an electric pump-fed engine. The rocket also carried an additional satellite payload called "Humanity Star", a 1-meter-wide (3 ft) carbon fiber sphere made up of 65 panels that reflect the Sun's light. [35]
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
A Soyuz-FG rocket launches from "Gagarin's Start" (Site 1/5), Baikonur Cosmodrome. A rocket (from Italian: rocchetto, lit. ''bobbin/spool'', and so named for its shape) [nb 1] [1] is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. [2]
RS-68 being tested at NASA's Stennis Space Center Viking 5C rocket engine used on Ariane 1 through Ariane 4. A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket.
In the early 1930s, Forman and Parsons began to realize that the rocket technology was a more complex subject than they had first assumed. [6]: 64–66 They corresponded with rocketry experts on both sides of the Atlantic, but Forman later reminisced that they learned very little beyond the fact that nobody else had yet achieved much.
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 V. P. Glushko Museum of Cosmonautics and Rocket Technology is a memorial museum telling about the beginning of the domestic space engine industry, including the history of GDL. The museum is located in the Peter and Paul Fortress, which in the 1930s housed GDL stands for testing rocket engines. It was opened on April 12, 1973.
