Hopi Dart
Hopi-Dart was an American sounding rocket used by the NASA Marshall Space Flight Center for aeronomy studies in the early 1960s. Design Hopi-Dart was a two-stage vehicle, combining a solid-fuelled Hopi III first stage with an unpowered Dart second stage. It was originally capable of carrying a payload of to an apogee of ; an upgrade, sometimes known as "Hopi Plus", increased the apogee to .Jacobs and Whitney 1962, p. 80. The Hopi-Dart was developed for NASA Marshall Space Fight Center to obtain wind speeds at altitudes from 70 to 90 kilometers in support of Saturn launches. Design was headed by Charles W. Watson.Morris and Pines 2000, p. 195. Operational history Eleven test and eleven operational aeronomy missions were flown, with Wallops Island, the Tonopah Test Range, and the Cape Canaveral Air Force Station Launch Complex 43 Launch Complex 43 (LC-43) at Cape Canaveral Space Force Station, Florida was a launch complex used by American sounding rockets between 1962 and ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Marshall Space Flight Center
The George C. Marshall Space Flight Center (MSFC), located in Redstone Arsenal, Alabama (Huntsville postal address), is the U.S. government's civilian rocketry and spacecraft propulsion research center. As the largest NASA center, MSFC's first mission was developing the Saturn launch vehicles for the Apollo program. Marshall has been the lead center for the Space Shuttle main propulsion and external tank; payloads and related crew training; International Space Station (ISS) design and assembly; computers, networks, and information management; and the Space Launch System (SLS). Located on the Redstone Arsenal near Huntsville, MSFC is named in honor of General of the Army George C. Marshall. The center contains the Huntsville Operations Support Center (HOSC), also known as the International Space Station Payload Operations Center. This facility supports ISS launch, payload, and experiment activities at the Kennedy Space Center. The HOSC also monitors rocket launches from Cape ...

Aeronomy
Aeronomy is the scientific study of the upper atmosphere of the Earth and corresponding regions of the atmospheres of other planets. It is a branch of both atmospheric chemistry and atmospheric physics. Scientists specializing in aeronomy, known as aeronomers, study the motions and chemical composition and properties of the Earth's upper atmosphere and regions of the atmospheres of other planets that correspond to it, as well as the interaction between upper atmospheres and the space environment. In atmospheric regions aeronomers study, chemical dissociation and ionization are important phenomena. History The mathematician Sydney Chapman introduced the term ''aeronomy'' to describe the study of the Earth's upper atmosphere in 1946 in a letter to the editor of ''Nature'' entitled "Some Thoughts on Nomenclature." The term became official in 1954 when the International Union of Geodesy and Geophysics adopted it. "Aeronomy" later also began to refer to the study of the corresponding ...

Solid Fuel Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Arabs, Chinese, Persians, Mongols, and Indians as early as the 13th century. All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation and because they almost always launch reliably, they have been frequently used in military applications such as missiles. The lower performance of solid propellants (as compared to liquids) does not favor their use as primary propulsion in modern ...

Apogee
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallops Island
Wallops Island is a island in Accomack County, Virginia, part of the Virginia Barrier Islands that stretch along the eastern seaboard of the United States of America. It is just south of Chincoteague Island, a popular tourist destination. Wallops Island proper, originally known as Kegotank Island, was granted to John Wallop by the Crown on April 29, 1692. Ownership was divided through the years, until the Commonwealth of Virginia seized the property in 1876 and 1877 in lieu of unpaid taxes. From 1877, ownership was again divided and subdivided until 1889, when it was held by various trustees for the Wallops Island Club. The Club was incorporated and assumed ownership in 1933 as the Wallops Island Association, Inc. Association members and their families spent the summers fishing and swimming on the island. The Association grazed sheep, cattle, and ponies on the area until the mid-1940s. In 1947, the U.S. Navy began using the upper two-thirds of the island on a lease-rental bas ...

Tonopah Test Range
The Tonopah Test Range (TTR, also designated as Area 52) is a highly classified, restricted military installation of the United States Department of Defense, and United States Department of Energy ( nuclear stockpile stewardship) located about southeast of Tonopah, Nevada. It is part of the northern fringe of the Nellis Range, measuring . Tonopah Test Range is located about northwest of Groom Lake, the home of the Area 51 facility. Like the Groom Lake facility, Tonopah is a site of interest to conspiracy theorists, mostly for its use of experimental and classified aircraft. As such, it is not generally the focus of alien enthusiasts, unlike its neighbor. It is currently used for nuclear weapons stockpile reliability testing, research and development of fusing and firing systems, and testing nuclear weapon delivery systems. The airspace comprises restricted area R-4809 of the Nevada Test and Training Range and is often used for military training. Description The Tonop ...
