Point Arguello
Point Arguello ( Spanish: ''Punta Argüello'') is a headland on the Gaviota Coast, in Santa Barbara County, California, near the city of Lompoc. The area was first used by the United States Navy in 1959 for the launch of military and sounding rockets. It was transferred to the United States Air Force in 1964, at which time it became part of Vandenberg Air Force Base. History In 1769, the Spanish Portola expedition became the first Europeans to explore this area by land. Soldiers of the expedition named a nearby point Los Pedernales or Punta Pedernales, because they found flints there. The point was given that name on some early maps, but in 1792 British naval explorer George Vancouver dubbed it Point Arguello for José Darío Argüello, a Spanish frontier soldier who was Commandant of the Presidio of Santa Barbara and acting governor of Alta California. wrecked off Point Argüello in 1849. A High-frequency direction finding (HFDF) was established here by the Navy dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlas V
Atlas V is an expendable launch system and the fifth major version in the Atlas (rocket family), Atlas launch vehicle family. It was developed by Lockheed Martin and has been operated by United Launch Alliance (ULA) since 2006. Primarily used to launch payloads for the United States Department of Defense, NASA, and commercial customers, Atlas V is the longest-serving active rocket in the United States. Each Atlas V vehicle consists of two main stages. The First stage (rocketry), first stage is powered by a single Russian-made RD-180 engine that burns kerosene and liquid oxygen. The Centaur (rocket stage), Centaur upper stage uses one or two American-made Aerojet Rocketdyne RL10 engines that burn liquid hydrogen and liquid oxygen. Strap-on booster, Strap-on Solid rocket booster, solid rocket boosters (SRBs) are used in several configurations. Originally equipped with AJ-60A SRBs, the vehicle switched to Graphite-Epoxy Motor (GEM 63) boosters beginning in November 2020, except for ...

Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first-stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low Earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V, which is still in use . Background In May 1988, the US Air Force chose General Dynamics (now Lockheed Martin) to develop the Atlas II vehicle, primarily to launch Defense Satellite Communications System payloads under the Medium Launch Vehicle II (MLV-II) p ...

Atlas H
The Atlas H was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas (rocket family), Atlas family of rockets, and was used to launch five clusters of Naval Ocean Surveillance System, NOSS satellites for the US National Reconnaissance Office. Two flights also carried Living Plume Shield (satellite), LiPS satellites, as secondary payloads for the United States Naval Research Laboratory. The Atlas H was a stage and a half rocket, using the enhanced Atlas rocket designed for use as the first stage of the Atlas G rocket, which differed from the Atlas H in having a Centaur (rocket stage), Centaur upper stage. This stage was later reused as the first stage of the Atlas I. In practice, an MSD (rocket stage), MSD upper stage was flown on all five launches. Atlas H could put a payload of 3,630 kg (8,000 lb) into low Earth orbit, or a payload of 2,255 kg (4,971 lb) into a geostationary transfer orbit. Launches The At ...

Atlas E/F
The Atlas E/F (or SB-1A) was an American expendable launch system and sounding rocket built using parts of decommissioned SM-65 Atlas missiles. It was a member of the Atlas (rocket family), Atlas family of rockets. The first stage was built using parts taken from decommissioned SM-65E Atlas, Atlas-E and SM-65F Atlas, Atlas-F missiles, with various solid rocket, solid propellant upper stages used depending on the requirements of the payload. The Atlas E/F was also used without an upper stage for a series of re-entry vehicle tests. On a single launch, an RM-81 Agena liquid-propellant upper stage was used. Variants Atlas E/F Thirty Atlas E/F rockets were launched without upper stages for ABRES and BMRS re-entry vehicle tests between 1965 and 1974. Three of these launches failed. Five ABRES launches were also conducted while the missiles were still operational, but did not use the Atlas E/F configuration. Atlas E/F-Agena An RM-81 Agena upper stage was used on a f ...

Thorad-Agena
Thorad-Agena was an American expendable launch system, derived from the Thor and Delta rockets. The first stage of the rocket was a stretched Thor variant named "Long Tank Thrust Augmented Thor". The Long Tank Thor first stage was later adopted by NASA's Delta program for its "Thrust Augmented Improved Delta", which first flew in 1968. The second stage was the Agena-D, which had already been used in conjunction with the standard configuration Thor, as the Thor-Agena. Three Castor rockets would be used as boosters. Most launches carried Corona (KeyHole) reconnaissance satellites, particularly spacecraft of the KH-4 series, however some scientific and technology development satellites were also flown, mostly towards the end of the program. Configurations The Thorad-Agena was flown in two different configurations, the SLV-2G, and the SLV-2H. These differed in that the SLV-2G used Castor 1 strap-on boosters, whereas the 2H used Castor 2s. Launches Forty-three launches too ...

Thor-Agena
Thor-Agena was a series of orbital launch vehicles. The launch vehicles used the Douglas Aircraft Company, Douglas-built Thor (rocket family), Thor first Multistage rocket, stage and the Lockheed Corporation, Lockheed-built RM-81 Agena, Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta (rocket family), Delta rocket family. The first attempted launch of a Thor-Agena was in January 1959. The first successful launch was on 28 February 1959, launching ''Discoverer 1''. It was the first two-stage launch vehicle to place a satellite into orbit. Missions Among other uses, the clandestine CORONA (satellite), CORONA program used Thor-Agena from June 1959 until January 1968 to launch United States military reconnaissance satellites operated by the Central Intelligence Agency (CIA). During this program, Thor-Agena launch vehicles were used in 145 launch attempts, now known to have been part of satellite surveillance programs. Also, ' ...

Atlas-Agena
The Atlas-Agena was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas (rocket family), Atlas family of rockets, and was launched 109 times between 1960 and 1978. It was used to launch the first five Mariner program, Mariner uncrewed probes to the planets Venus and Mars, and the Ranger program, Ranger and Lunar Orbiter program, Lunar Orbiter uncrewed probes to the Moon. The upper stage was also used as an uncrewed orbital Agena target vehicle, target vehicle for the Project Gemini, Gemini crewed spacecraft to practice space rendezvous, rendezvous and docking and berthing of spacecraft, docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified DoD payloads.

Vandenberg Space Launch Complex 3
Space Launch Complex 3 (SLC-3) is a launch site at Vandenberg Space Force Base that consists of two separate launch pads. Space Launch Complex 3 East (SLC-3E) was used by the Atlas V launch vehicle before it was decommissioned in August 2021 with the final launch taking place on November 10, 2022, at 09:49, while Space Launch Complex 3 West (SLC-3W) has been demolished. Launches from Vandenberg fly southward, allowing payloads to be placed in high-inclination orbits such as polar or Sun-synchronous orbit, which allow full global coverage on a regular basis and are often used for weather, Earth observation, and reconnaissance satellites. These orbits are difficult to reach from Cape Canaveral Space Force Station, where launches must fly eastward due to major population centers to both the north and south of Kennedy Space Center. Avoiding these would require hugely inefficient maneuvering, greatly reducing payload capacity. SLC-3E was the launch site of the Mars lander ''InSight ...
