Vulcan Centaur is a heavy-lift launch vehicle [a] developed and operated by United Launch Alliance (ULA). It is a two-stage-to-orbit launch vehicle consisting of the Vulcan first stage and the Centaur second stage.
It was launched on the maiden flight of Vulcan Centaur on 8 January 2024, 07:18 UTC. [1] The Vulcan Centaur successfully placed Peregrine into trans-lunar injection , however, following a fuel leak with the spacecraft unrelated to the Vulcan Centaur, the lander failed in its attempt to land on the moon.
On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. As of July 2024, Vulcan Centaur has completed one certification flight launch and another is left be fully certified for national security launches.
The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum.
The Vulcan Centaur is a heavy-lift launch vehicle developed by ULA integrating technology from both its prior Atlas and Delta rocket families along with advancements. Vulcan has been designed to meet the requirements of the National Security Space Launch (NSSL) program and be capable of achieving human-rating certification to allow the launch ...
Good news and bad news. The good news is that losing a nozzle only decreased the rocket's efficiency. The fuel still burned. It still got pushed out in the right direction (i.e., down).
First fired in 2020, it is used on the Vulcan launch vehicle beginning with the first launch on January 8, 2024. [4] [9] [10] Up to 6 of the boosters will be mounted on a single Vulcan core, depending on customer needs. [11] It is currently used on Vulcan Centaur rocket. [2]
The Centaur D-1T (powered by RL10A-3-3 engines) was an improved version for use on the far more powerful Titan III booster in the 1970s, [48] with the first launch of the resulting Titan IIIE in 1974. The Titan IIIE more than tripled the payload capacity of Atlas-Centaur, and incorporated improved thermal insulation, allowing an orbital ...
