Broglio Space Centre
The Luigi Broglio Space Center (BSC) is an Italian-owned spaceport near Malindi, Kenya, named after its founder and Italian space pioneer Luigi Broglio. Developed in the 1960s through a partnership between the Sapienza University of Rome's Aerospace Research Centre and NASA, the BSC served as a spaceport for the launch of both Italian and international satellites (1967–1988). The center comprises a main offshore launch site, known as the San Marco platform, as well as two secondary control platforms and a communications ground station on the mainland. In 2003, a legislative decree handed the Italian Space Agency management of the center, beginning in 2004, and the name changed from the previous San Marco Equatorial Range. While the ground station is still in use for satellite communications, the BSC is not currently used as a launch site. History The San Marco platform was a former oil platform, located to the north of Cape Ras Ngomeni on the coastal sublittoral of Kenya, ...

Scout (rocket Family)
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970. The original Scout (an acronym for Solid Controlled Orbital Utility Test system) was designed in 1957 at the NACA, at Langley center. Scout launch vehicles were used from 1961 until 1994. To enhance reliability the development team opted to use "off the shelf" hardware, originally produced for military programs. According to the NASA fact sheet: "... the first stage motor was a combination of the Jupiter Senior and the Navy Polaris; the second stage came from the Army MGM-29 Sergeant; and the third and fourth stage motors were designed by Langley engineers who adapted a version of the Navy Vanguard." The first successful orbital launch of a Sco ...

Ground Station
A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna. Ground stations may have either a fixed or itinerant position. Article 1 § III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their interre ...

Uhuru (satellite)
Uhuru was the first satellite launched specifically for the purpose of X-ray astronomy. It was also known as the X-ray Explorer Satellite, SAS-A (for Small Astronomy Satellite A, being first of the three-spacecraft SAS series), SAS 1, or Explorer 42. The space observatory, observatory was launched on December 12, 1970 into an initial orbit of about 560 km apogee, 520 km perigee, 3 degrees inclination, with a period of 96 minutes. The mission ended in March 1973. Uhuru was a scanning mission, with a spin period of ~12 minutes. It performed the first comprehensive survey of the entire sky for X-ray sources, with a sensitivity of about 0.001 times the intensity of the Crab nebula. Objectives The main objectives of the mission were: * To survey the sky for cosmic X-ray sources in the 2–20 keV range to a limiting sensitivity of 1.5 × 10−18 joule/(cm2-sec), 5 × 10−4 the flux from the Crab Nebula * To determine discrete source locations with a precision of a few square ...

Solid-propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which is contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel are two ...

Nike Tomahawk
The Nike stage or Nike booster, a solid fuel rocket motor, was created by Hercules Aerospace for the Nike Ajax (M5) Nike Hercules (M5E1) (and M88 late in Hercules career). It was developed for use as the first stage of the Nike Ajax and Nike Hercules missiles as part of Project Nike. It was subsequently employed in a variety of missiles and multi-stage sounding rockets, becoming one of the most popular and reliable rocket stages, not only in the United States, but also in several other countries around the world.Corliss 1972 p. 24 Sounding rockets based on Nike Booster *The Nike Deacon has a ceiling of 189 km, a takeoff thrust of 217 kN, a takeoff weight of 710 kg, a diameter of 0.42 m and a length of 7.74 m. * The Nike Javelin was launched 34 times between 1964 and 1978.

Nike Apache
The Nike Apache, also known as Argo B-13, was a two-stage sounding rocket developed by Aerolab, later Atlantic Research, for use by the United States Air Force and NASA. It became the standard NASA sounding rocket and was launched over 600 times between 1961 and 1978. Development The TE-307-2 Apache rocket motor was developed by Thiokol as an improvement of its Cajun series of rockets; the Apache was similar in appearance to Cajun, but had an improved propellant that allowed for better performance. Combined with a M5 Nike rocket booster for its first stage by Aerolab,Parsch 2004 the Nike-Apache sounding rocket was capable of lifting of instruments to an apogee of .Corliss 1971, p.82. Operational history The first launch of Nike-Apache was conducted by the United States Air Force on 17 February 1961. Popular due to its low cost (US$6,000) and ability to be fired from many locales, 636 launches were conducted between 1961 and 1978, with the final launch of a Nike-Apache taking pla ...

Sounding Rockets
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). Etymology The origin of the term ...

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 ...

Nairobi
Nairobi ( ) is the capital and largest city of Kenya. The name is derived from the Maasai phrase ''Enkare Nairobi'', which translates to "place of cool waters", a reference to the Nairobi River which flows through the city. The city proper had a population of 4,397,073 in the 2019 census, while the metropolitan area has a projected population in 2022 of 10.8 million. The city is commonly referred to as the Green City in the Sun. Nairobi was founded in 1899 by colonial authorities in British East Africa, as a rail depot on the Uganda - Kenya Railway.Roger S. Greenway, Timothy M. Monsma, ''Cities: missions' new frontier'', (Baker Book House: 1989), p.163. The town quickly grew to replace Mombasa as the capital of Kenya in 1907. After independence in 1963, Nairobi became the capital of the Republic of Kenya. During Kenya's colonial period, the city became a centre for the colony's coffee, tea and sisal industry. The city lies in the south central part of Kenya, at an elevation ...
