Vandenberg Air Force Base Space Launch Complex 6
Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts. The site was originally envisioned to support Titan IIIM rockets and the Manned Orbiting Laboratory, however, these projects were terminated before SLC-6's completion. Between 1979 and 1986 the facilities received extensive modifications to accommodate the Space Shuttle. However, budgetary constraints, safety considerations, and political factors ultimately led to the cancellation of Shuttle operations from the West Coast. SLC-6 facilitated four launches of Athena rockets between 1995 and 1999 with minimal modifications. Subsequently, it underwent modifications to support the Delta IV and Delta IV Heavy, which conducted ten successful missions between 2006 and 2022. I ...

Delta IV Heavy
The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It had the highest capacity of any operational launch vehicle in the world after the retirement of the Space Shuttle in 2011 until the Falcon Heavy debuted in 2018, and it was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024. It was manufactured by United Launch Alliance (ULA) and was first launched in 2004. Delta IV Heavy was the last operating member of the Delta IV family, and its final flight was on 9 April 2024. It is succeeded by the Vulcan Centaur rocket. The Delta IV Heavy first stage consisted of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift-off, all three rocket engines would operate at full thrust, and 44 seconds later the central engine would throttle down to 5 ...

OmegA
Omega (, ; uppercase Ω, lowercase ω; Ancient Greek ὦ, later ὦ μέγα, Modern Greek ωμέγα) is the twenty-fourth and last letter in the Greek alphabet. In the Greek numerals, Greek numeric system/isopsephy (gematria), it has a value of 800. The word literally means "great O" (''o mega'', mega meaning "great"), as opposed to omicron, which means "little O" (''o mikron'', mikron meaning "little"). In Phonetics, phonetic terms, the Ancient Greek Ω represented a vowel length, long open-mid back rounded vowel , comparable to the "aw" of the English language, English word ''raw'' in dialects without the cot–caught merger, in contrast to omicron, which represented the close-mid back rounded vowel , and the digraph (orthography), digraph ''ου'', which represented the vowel length, long close-mid back rounded vowel . In Modern Greek, both omega and omicron represent the mid back rounded vowel or . The letter omega is transliteration, transliterated into a Lati ...

Space Shuttle Discovery And SCA Over Vandenberg AFB SLC-6 - DF-SC-85-09923
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as ''spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a better model for ...

Mothball
Mothballs are small balls of chemical pesticide and deodorant, sometimes used when storing clothing and other materials susceptible to damage from silverfish, Mold (fungus), mold or moth larvae (especially clothes moths like ''Tineola bisselliella''). Composition Older mothballs consisted primarily of naphthalene, but due to naphthalene's flammability, many modern mothball formulations instead use 1,4-dichlorobenzene. The latter formulation may be somewhat less flammable, although both chemicals have the same NFPA 704 rating for flammability. The latter chemical is also variously labeled as 1,4-Dichlorobenzene, para-dichlorobenzene, p-dichlorobenzene, P-DCB, pDCB, or PDB (Palm OS), PDB, making it harder to identify unless all these names and initialisms are known to a potential purchaser. Both of these formulations have the strong, pungent, sickly-sweet odor often associated with mothballs. Both naphthalene and 1,4-dichlorobenzene undergo Sublimation (phase transition), subli ...

Titan III
Titan was a family of United States expendable rockets used between 1959 and 2005. The Titan I and Titan II were part of the US Air Force's intercontinental ballistic missile (ICBM) fleet until 1987. The space launch vehicle versions contributed the majority of the 368 Titan launches, including all the Project Gemini crewed flights of the mid-1960s. Titan vehicles were also used to lift US military payloads as well as civilian agency reconnaissance satellites and to send interplanetary scientific probes throughout the Solar System. Titan I missile The HGM-25A Titan I, built by the Martin Company, was the first version of the Titan family of rockets. It began as a backup ICBM project in case the SM-65 Atlas was delayed. It was a two-stage rocket operational from early 1962 to mid-1965 whose LR-87 booster engine was powered by RP-1 (kerosene) and liquid oxygen (LOX). The ground guidance for the Titan was the UNIVAC ATHENA computer, designed by Seymour Cray, based in a har ...

LORAN
LORAN (Long Range Navigation) was a hyperbolic navigation, hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee (navigation), Gee system but operated at lower frequencies in order to provide an improved range up to with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater during World War II. LORAN, in its original form, was an expensive system to implement, requiring a cathode ray tube (CRT) display and a well trained operator. This limited use to the military and large commercial users. Automated receivers became available in the 1950s, but the same improved electronics also opened the possibility of new systems with higher accuracy. The U.S. Navy began development of Loran-B, which offered accuracy on the order of a few tens of feet, but ran into signi ...

Point Arguello Light
Point Arguello Lighthouse is a lighthouse on Point Arguello in Santa Barbara County, California, serving the Santa Barbara Channel on the Gaviota Coast adjoining Vandenberg Space Force Base near the city of Lompoc, California. The original Point Arguello lighthouse, built in 1901, had a white square tower attached to a one-story keeper's house. It had a fourth order Fresnel lens, which was transferred from the Point Hueneme Lighthouse. The tower was replaced in 1934 by a square pyramidal skeletal steel tower, which was in turn replaced by the current post light. History Point Arguello The area of land now known as Point Arguello was originally known by the ' Chumashan—Canalino Indian' name "Nocto" and was part of the territory ruled by Chief Salipuata at the time of the occupation by the Spanish missionaries. The Native Americans were part of the third indigenous people in the area, the Canalino branch of the Chumash people. In Paleo-indian times, a people of Mongolian her ...

Eminent Domain
Eminent domain, also known as land acquisition, compulsory purchase, resumption, resumption/compulsory acquisition, or expropriation, is the compulsory acquisition of private property for public use. It does not include the power to take and transfer ownership of private property from one property owner to another private property owner without a valid public purpose. This power can be legislatively delegated by the state to municipalities, government subdivisions, or even to private persons or corporations, when they are authorized to exercise the functions of public character. The most common uses of property taken by eminent domain have been for roads, government buildings and public utility, public utilities. Many railroads were given the right of eminent domain to obtain land or easements in order to build and connect rail networks. In the mid-20th century, a new application of eminent domain was pioneered, in which the government could take the property and transfer it to ...

Athena (rocket Family)
Athena was a 1990s Lockheed Martin expendable launch system which underwent several name changes in its lifetime. Development began at the Lockheed Corporation in 1993, where the design was known as the Lockheed Launch Vehicle. The name was subsequently changed to the Lockheed Martin Launch Vehicle when Lockheed merged with Martin Marietta. In 1997 the name was finally changed to Athena, and all of the launches after the demonstration flight in August 1995 were conducted using that name. Athena was retired from service in 2001, but in September 2010 Athena was added to NASA's Launch Services II contract. It was announced that it would be put back into production, with launches set to resume in 2012. All production had ceased by March 2017. Variants The Athena comes in two versions, Athena I and Athena II. The Athena I has two stages, the Thiokol Castor (rocket stage), Castor-120 first stage and a Pratt & Whitney ORBUS 21D upper stage, both powered by Solid-fuel rocket, solid pr ...
