A dart is the free flying final stage of a sounding rocket, and contains the payload. Its form is very aerodynamically designed. After the launch stage burned out the dart is detached and continues to rise only with its own inertia.
Some sounding rockets are available both with or without dart. The version without a dart is able to transport more payload, but reaches lesser height.
An expendable launch system is a launch vehicle that can be launched only once, after which its components are either destroyed during reentry or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2022, most satellites and human spacecraft are currently launched on ELVs. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are proven technology in widespread use for many decades.
The Ariane 4 was a European expendable launch vehicle, developed by the Centre national d'études spatiales (CNES), the French space agency, for the European Space Agency (ESA). It was manufactured by ArianeGroup and marketed by Arianespace. Since its first flight on 15 June 1988 until the final flight on 15 February 2003, it attained 113 successful launches out of 116 total launches.
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 above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km and the minimum for satellites is approximately 121 km. Certain sounding rockets have an apogee between 1,000 and 1,500 km, 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.
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket stages, each of which contains its own engines and propellant. A tandem or serial stage is mounted on top of another stage; a parallel stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched.
The Black Brant is a family of Canadian-designed sounding rockets originally built by Bristol Aerospace, since absorbed by Magellan Aerospace in Winnipeg, Manitoba. Over 800 Black Brants of various versions have been launched since they were first produced in 1961, and the type remains one of the most popular sounding rockets. They have been repeatedly used by the Canadian Space Agency and NASA.
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs.
The Mohr Rocket was a sounding rocket developed by Ernst Mohr in Wuppertal, Germany.
Aries is an American sounding rocket and target rocket, developed by Space Vector Corporation from retired LGM-30 Minuteman I intercontinental ballistic missile (ICBM) stages for use by the United States Air Force and NASA. Taken over by Orbital Sciences Corporation, Aries, as the Target Test Vehicle, remains in use.
Loki, officially designated 76mm HEAA Rocket T220, was an American unguided anti-aircraft rocket based on the German Taifun. Like the Taifun, Loki never saw service in its original role, but later found widespread use as a sounding rocket. It was so successful in this role that several advanced versions were developed on the basic Loki layout, including the final Super Loki.
The Judi-Dart is a United States solid fueled sounding rocket .It was manufactured by Rocket power Inc .It belonged to the Loki rocket family. The Judi-Dart was launched 89 times between 1964 and 1970. The Judi-Dart has a length of 2.70 metres, a diameter of 0.08 metres, a maximum flight altitude of 65 kilometres and a launch thrust of 9000 newtons.
Hopi-Dart was an American sounding rocket used by the NASA Marshall Space Flight Center for aeronomy studies in the early 1960s.
S-Series is a fleet of sounding rockets funded by the Japan Aerospace Exploration Agency (JAXA) that have been in service since the late 1960s. Manufactured by IHI Aerospace and operated by the Institute of Space and Astronautical Science (ISAS). The nomenclature of the S-Series rockets is the number of "S"s indicates the number of stages, and the following number details the diameter of the craft in millimeters. For example, the S-310 is a single stage rocket with a diameter of 310 mm.
Falcon 9 is a partially reusable medium-lift launch vehicle that can carry cargo and crew into Earth orbit, designed, manufactured and launched by American aerospace company SpaceX. It can also be used as an expendable heavy-lift launch vehicle. The first Falcon 9 launch was on 4 June 2010. The first Falcon 9 commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012. In 2020 it became the first commercial rocket to launch humans to orbit and remains the only such vehicle. It is the only U.S. rocket certified for transporting humans to the ISS. In 2022, it became the U.S. rocket with the most launches in history and with the best safety record, having suffered just one flight failure.
Rehbar is a series of sounding rockets launched into the upper atmosphere by Pakistan's Space and Upper Atmosphere Research Commission (SUPARCO). Rehbar-I was the first rocket launched by SUPARCO, on 7 June 1962. Rehbar-I was a two-staged solid fuel rocket.
The Atlas E/F 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 family of rockets.
Rohini is a series of sounding rockets developed by the Indian Space Research Organisation (ISRO) for meteorological and atmospheric study. These sounding rockets are capable of carrying payloads of 2 to 200 kilograms between altitudes of 100 to 500 kilometres. The ISRO currently uses RH-200, RH-300,Mk-II, RH-560 Mk-II and RH-560 Mk-III rockets, which are launched from the Thumba Equatorial Rocket Launching Station (TERLS) in Thumba and the Satish Dhawan Space Center in Sriharikota.
The Terrier Malemute is a two-stage American sounding rocket typically used for smaller payloads. Both the Terrier first stage and the Malemute second stage use solid fuel. The Terrier burns for approximately 5.2 seconds, and the Malemute burns for approximately 21.5 seconds. The first stage booster consists of a surplus Navy Terrier MK 12 Mod 1 rocket motor with four 0.22 m2 (340 sq in) fin panels arranged in a cruciform configuration. The Terrier rocket booster has a diameter of 460 mm (18 in). The second stage solid rocket is a Thiokol Malemute TU-758 rocket motor, specially designed for high altitude research rocket applications. Apogee is approximately 400 km (220 nmi) for a 230 kg (510 lb) payload or 700 km (380 nmi) for a 41 kg (90 lb) payload. For a payload weight of 200 lb (91 kg), the acceleration during the boost phase is 26 g. Its first flight was on November 11, 1974, from Barking Sands. Other launch sites have included Poker Flat, Wallops Island and Fort Yukon, Alaska.
