Launcher
An orbital launch vehicle is a multi-stage rocket that is used to transport people or payloads into earth orbit or an escape path and is thus a system for operating space travel . The payload is almost always located under a payload fairing that protects it from external influences before and during take- off.
distribution
Using launch vehicles such as the American Atlas , Titan , Saturn , Falcon , as well as the Soviet Vostok , Voschod , Soyuz and the Chinese Long March 2E , people were and are being transported into space . The American space transportation system , consisting of a space shuttle , tank and boosters , was also a launch vehicle.
The most famous European launcher is the Ariane in the current Ariane 5 ECA . It is one of the few missile types that have a double launch device and are designed for the launch of two large payloads.
The most powerful launch vehicles ever built were the American Saturn V and the Soviet Energija . The most powerful launch vehicle currently in use is the Falcon Heavy , developed and built by SpaceX , which made its maiden flight from Kennedy Space Center on February 6, 2018 . The most powerful Russian launch vehicle in use is the Proton-M . The most powerful European launcher is the Ariane 5 ECA , and the most powerful Chinese launcher is the Langer Marsch 5 .
Overview of today's launch vehicles
This table contains all currently available orbital launch vehicles as well as rockets that will with sufficient certainty complete their first flights in the near future or for which launches have already been booked.
Status: January 2021
- ↑ a b c d e f g h i j k l m n o p q r s t u Rocket not yet flown with booked payloads
- ↑ a b c d So far only false starts
- ↑ So far only suborbital test flights; Payloads have already been booked.
- ↑ a b Not yet flown rocket with no published payloads
- ↑ a b With the additional level " interplanetary photon " currently being developed, GTO or GEO missions are just as possible as interplanetary flights; a first start is planned for mid-2021 with the lunar orbiter Capstone .
- ↑ a b Rocket not yet flown, payloads so far only booked for LEO flights, also takes part in tenders for GTO missions.

Reusability
Most launch vehicles built today can only be launched once. Therefore, they are referred to as disposable rocket or disposable rocket . The rocket stages are detached after burnout, fall back to Earth, and are destroyed when re-entering the atmosphere. Upper grades often remain in orbit as space debris for long periods of time .
An exception was the space shuttle , where the solid fuel boosters and of course the orbiter were used several times. Only the external tank was lost. The boosters of the Soviet Energija rocket were also designed to land on parachutes, but the program was discontinued before this could be tested.
SpaceX is pursuing a different approach with the launchers Falcon 9 and Falcon Heavy . Here the stage separation takes place before the first stage is burned out. It then lands, controlled by grid fins , on a floating platform in the ocean ( autonomous spaceport drone ship ) or flies under its own power to the landing zone and lands softly there . This was achieved for the first time on Falcon 9 Flight 20 in December 2015. Reusability was demonstrated in March 2017 when a first stage that had already been flown was used for the first time.
Various manufacturers are now developing systems similar to SpaceX. The New Glenn and the Chinese Langer Marsch 8R and Hyperbola-2 rockets are said to have a reusable, vertically landing first stage. The ArianeGroup is also working on such a project under the name Themis . In the case of the Vulcan and Prime , however, only the engine unit of the first stage should be dropped and used again.
With the new two-stage large rocket Starship and Super Heavy , SpaceX is aiming for complete reusability for the first time.

The relatively low success rate in 2020 can be explained by the relatively high number of first flights of new rocket models. The frequency of failures is many times greater than with tried-and-tested rocket types.
The launches were distributed among countries, launch vehicles and launch sites as follows:

Launcher projects
The following orbital launch vehicles have been in active development for several years, and information on the structure and payload capacity as well as planning for the first flight are already available; however, they do not yet meet the criteria for inclusion in the overview of today's launch vehicles .
In addition, there are numerous projects for new launch vehicles that are still at an early stage or no longer show any progress.
