Space launch

The Space Launch System of Artemis II. Earliest phase of a flight that reaches space A space launch is the phase of a spaceflight mission during which a launch vehicle reaches space. The launch may be sub-orbital or the launch may continue until the vehicle reaches orbit. A space launch begins at a launch pad, which may be on land or at sea, or when the launch vehicle is released mid-air from an aircraft. History Following the end of the Space Race, spaceflight has been characterized by greater international cooperation, cheaper access to low Earth orbit and an expansion of commercial ventures. Interplanetary probes have visited all of the planets in the Solar System, and humans have remained in orbit for long periods aboard space stations such as Mir and the ISS. Most recently, China has emerged as the third nation with the capability to launch independent crewed missions, while operators in the commercial sector have developed reusable booster systems and craft launched from airborne platforms. In 2020, SpaceX became the first commercial operator to successfully launch a crewed mission to the International Space Station with Crew Dragon Demo-2. [citation needed] Rocket propulsion
