A Falcon 9 first-stage booster is a reusable rocket booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX. The manufacture of first-stage booster constitutes about 60% of the launch price of a single expended Falcon 9 (and three of them over 80% of the launch price of an expended Falcon Heavy), which led SpaceX to develop a program dedicated to recovery and reuse of these boosters. After multiple attempts, some as early as 2010, at controlling the re-entry of the first stage after its separation from the second stage, the first successful controlled landing of a first stage occurred on 22 December 2015, on the first flight of the Full Thrust version. Since then, Falcon 9 first-stage boosters have been landed and recovered times out of attempts, including synchronized recoveries of the side-boosters of most Falcon Heavy flights. In total recovered boosters have been refurbished and subsequently flown at least a second time, with a recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SpaceX Reusable Launch System Development Program
SpaceX has private spaceflight, privately funded the development of Orbital spaceflight, orbital spacecraft, launch systems that can be reusable launch vehicle, reused many times, similar to the reusability of aircraft. SpaceX has developed technologies since the 2010s to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle multistage rocket, first stage to the launch site within minutes and to return a second stage to the launch pad, following orbital realignment with the launch site and atmospheric entry, atmospheric reentry in up to 24 hours. SpaceX's long term goal would have been reusability of both stages of their orbital launch vehicle, and the first stage would be designed to allow reuse a few hours after return. Development of reusable second stages for Falcon 9 was later abandoned in favor of developing SpaceX Starship, Starship. However, SpaceX still developed reusable payload fairings for the ...

SLC-4E
Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Space Force Base, California, U.S. It has two pads, both of which are used by SpaceX for Falcon 9, one for launch operations, and the other as Landing Zone 4 (LZ-4) for SpaceX landings. The complex was previously used by Atlas and Titan rockets between 1963 and 2005. It consisted of two launch pads: Space Launch Complex 4 West (SLC-4W, formerly PALC-2-3) and Space Launch Complex 4 East (SLC-4E, formerly PALC-2-4). Both pads were built for use by Atlas-Agena rockets, but were later rebuilt to handle Titan rockets. The designation SLC-4 was applied at the time of the conversion to launch Titan launch vehicles. Both pads at Space Launch Complex 4 are currently leased by SpaceX. SLC-4E is leased as a launch site for the Falcon 9 rocket, which first flew from Vandenberg on 29 September 2013, following a 24-month refurbishment program which had started in early 2011. SpaceX began a five-year lease of Launch C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booster (rocketry)
A booster is a rocket (or rocket engine) used either in the first stage of a multistage launch vehicle or in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are especially important for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as ''booster engine cut-off'' (BECO). Following booster separation, the rest of the launch vehicle continues flight with its core or upper-stage engines. The booster may be recovered, refurbished and reused, as was the case of the steel casings used for the Space Shuttle Solid Rocket Boosters. Drop-away engines The SM-65 Atlas rocket used three engines, one of which was fixed to the fuel tank, and two of which were mounted on a skirt which dropped away at BECO. This was used ...
