The Space Launch System ( SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first SLS launch was the uncrewed Artemis 1, which took place on 16 November 2022.
In 2022 NASA contracted with SpaceX to launch the Nancy Grace Roman Space Telescope on a Falcon Heavy for approximately $255 million, including launch service and other mission related costs. [99] The nearest competing U.S. rocket is ULA's Delta IV Heavy with a LEO payload capacity of 28.4 t (63,000 lb) costs US$12,340 per kg to LEO and US ...
This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets. For the simple list of all conventional ...
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than 50 metric tons (110,000 lb) [1] [2] by the United States and as more than 100 metric tons (220,000 lb) by Russia. [3] It is the most capable launch vehicle classification by mass to orbit, exceeding that of the ...
Despite thick fog around pad 39A, SpaceX's Falcon Heavy rocket launched from Kennedy Space Center with a Space Force mission at 9:41 a.m. EDT.
And by 2019, ULA, with their next-generation, lower-cost Vulcan/Centaur launch vehicle, was one of four launch companies competing for the US military's multi-year block-buy contract for 2022–2026 against SpaceX (Falcon 9 and Falcon Heavy), Northrop Grumman , and Blue Origin , where only the SpaceX vehicles are currently flying and the other ...
The Falcon Heavy is a super heavy-lift rocket developed and produced by SpaceX. It has been certified for the NSSL program after the STP-2 launch completed on 25 June 2019, as confirmed by the commander of the Air Force Space and Missile Systems Center, Lt. Gen. Thompson. [42]
Vulcan Centaur. Vulcan Centaur is a two-stage-to-orbit, expendable, heavy-lift launch vehicle created and operated by United Launch Alliance (ULA). It is principally designed for the United States Space Force 's National Security Space Launch (NSSL) program, which launches satellites for the Defense Department and U.S. intelligence agencies.
