Éridan (rocket)
The Éridan is a two-stage French sounding rocket, which resulted from the use of the Stromboli engine of the Dragon and/or Dauphin as first and second stage. It belonged thereby to a family of solid-propellant rockets from the Belier (rocket), the Centaure (rocket) Centaure was a two-stage French sounding rocket consisting of a Belier (rocket) starting stage and a Venus upper stage. It was operated by CNES between 1961 and 1986. The Centaure has been built in a number of 230 and has been launched from th ..., to the Dragon, the Dauphin and the Eridan. As the most powerful version of this series it could lift payloads from 100 to 420 kg to heights of 200 to a maximum of 460 km. Its climbing time is between 230 and 350 seconds.Les débuts de la recherche spatiale française 2846082154 IFHE,, Institut français d'histoire de l'espace - 2007 Intéressés, ils demandèrent au CNES d'envisager sérieusement un projet d'astronomie spatiale d'envergure qui serait réali ...

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).

Solid Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants Rocket propellant is the reaction mass of a rocket. This reaction mass is ejected at the highest achievable velocity from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical ... (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Mamluk Sultanate, Arabs, Dynasties in Chinese history, Chinese, Ilkhanate, Persians, Mongol Empire, Mongols, and Delhi Sultanate, 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 sol ...

Centaure (rocket)
Centaure was a two-stage French sounding rocket consisting of a Belier (rocket) starting stage and a Venus upper stage. It was operated by CNES between 1961 and 1986. The Centaure has been built in a number of 230 and has been launched from the CIEES/Hammaguir missile range, Reggane, CELPA, Salto di Quirra, Esrange, Thumba, Sonmiani, and Andøya Andøya is the northernmost island in the Vesterålen archipelago, situated about inside the Arctic circle. Andøya is located in Andøy Municipality in Nordland county, Norway. The main population centres on the island include the villages of .... It had a maximum payload of 60 kg, a maximum height of 140 km, a launch thrust of 44 kN, a launch weight of 457 kg, a diameter of 0.28 m and a length of 6.02 m. It belongs to a family of solid-propellant rockets consisting of the Belier, Centaure, Dragon, Dauphin, and Eridan rockets.

Dragon (rocket)
The Dragon is a two-stage French solid propellant sounding rocket used for high altitude research. The dragon's first stage was a Stromboli engine (diameter 56 cm) which burned 675 kg of fuel in 16 seconds and so produced a maximum thrust of 88 kN. A Bélier engine was used as the upper stage. It belonged thereby to a family of solid-propellant rockets derived from the Bélier, including the Centaure, the Dauphin and the Éridan. A payload of 30 to 120 kg could be carried on parabolic with apogees between 440 km (270 mi) (Dragon 2B) and 560 km (340 mi)(Dragon III) The Dragon was built in several versions including the Dragon-2B, and Dragon-3, Dragons have been launched from Andøya, Norway; Biscarrosse, France; Dumont d'Urville, Antarctica; Chamical, Argentina; CIEES in Hammaguir, Algeria ) , image_map = Algeria (centered orthographic projection).svg , map_caption = , image_map2 = , c ...

Kerguelen Islands
The Kerguelen Islands ( or ; in French commonly ' but officially ', ), also known as the Desolation Islands (' in French), are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than from Madagascar. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district. The main island, Grande Terre, is in area, about three quarters of the size of Corsica, and is surrounded by a further 300 smaller islands and islets, forming an archipelago of . The climate is harsh and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indig ...
