Kosmos 3M
The Kosmos-3M (russian: Космос-3М meaning "''Cosmos''", GRAU index 11K65M) was a Russian space launch vehicle, member of the Kosmos rocket family. It was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name. The Kosmos-3M used UDMH fuel and AK27I oxidizer ( red fuming nitric acid) to lift roughly of payload into orbit. It differed from the earlier Kosmos-3 in its finer control of the second-stage burn, allowing operators to tune the thrust and even channel it through nozzles that helped orient the rocket for the launching of multiple satellites at one time. PO Polyot manufactured these launch vehicles in the Russian city of Omsk for decades. It was originally scheduled to be retired from service in 2011; however, in April 2010 the Commander of the Russian Space Forces confirmed that it would be retired by the end of 2010. One further launch, with Kanopus-ST, was planned; however, this was cancelled in late 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

Unsymmetrical Dimethylhydrazine
Unsymmetrical dimethylhydrazine (UDMH; 1,1-dimethylhydrazine, НДМГ or codenamed Geptil) is a chemical compound with the formula H2NN(CH3)2 that is used as a rocket propellant. It is a colorless liquid, with a sharp, fishy, ammonia-like smell typical for organic amines. Samples turn yellowish on exposure to air and absorb oxygen and carbon dioxide. It is miscible with water, ethanol, and kerosene. In concentration between 2.5% and 95% in air, its vapors are flammable. It is not sensitive to shock. Symmetrical dimethylhydrazine, 1,2-dimethylhydrazine is also known but is not as useful. Production UDMH is produced industrially by two routes. Based on the Olin Raschig process, one method involves reaction of monochloramine with dimethylamine giving 1,1-dimethylhydrazinium chloride: :(CH3)2NH + NH2Cl → (CH3)2NNH2 ⋅ HCl In the presence of suitable catalysts, acetylhydrazine can be N-dimethylated using formaldehyde and hydrogen to give the N,N-dimethyl-N'-acetylhydrazine, w ...

BILSAT-1
BILSAT-1 (formerly just ''BILSAT'') was an earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY) and produced in Turkey as part of the Disaster Monitoring Constellation (DMC) project in the context of a show-how program led by DMC International Imaging of Surrey Satellite Technology (SSTL). Launch BILSAT-1 was launched from Plesetsk Cosmodrome Site 132/1, Arkhangelsk Oblast in Russia by a Kosmos-3M space launch vehicle on September 27, 2003 at 06:12 UTC in a multiple-satellite payload launch along with six other satellites, namely Mozhayets-4 and Larets of Russia, NigeriaSat of Nigeria, UK-DMC from the United Kingdom, South Korean STSAT-1 and Germany's Rubin 4-DS. It was placed in a polar, circular, sun-synchronous geocentric orbit at an altitude of with orbital parameters as period 98.5 min, apogee , perigee and inclination 98.2°.

Nadezhda (satellite)
Nadezhda (Russian: Надежда, means Hope in English) was a civilian satellite navigation system. Overview The system consisted of four satellites, each with a mass of 870 kg, diameter of 2m and length of 3.5. They orbit at an inclination of 89 degrees and an altitude of 1,000 km. The first three satellites received designations Kosmos 1383 (1982), Kosmos 1447 (1983), and Kosmos 1574 (1984). The satellites were first introduced in 1989. A newer version, called Nadezhda-M is reportedly smaller than the original one. It was due to be replaced by the Sterkh satellites. Nadezhda-M6 was launched on 28 June 2001.

Plesetsk
Plesetsk (russian: Плесе́цк) is an urban locality (a work settlement) and the administrative center of Plesetsky District, Arkhangelsk Oblast, Russia, situated about northeast of Moscow and south of Arkhangelsk. Municipally, it is the administrative center of Plesetskoye Urban Settlement, one of eight urban settlements in the district.

ABRIXAS
A Broadband Imaging X-ray All-sky Survey, or ABRIXAS was a space-based German X-ray telescope. It was launched on 28 April 1999 in a Kosmos-3M launch vehicle from Kapustin Yar, Russia, into Earth orbit. The orbit had a periapsis of , an apoapsis of , an inclination of 48.0° and an eccentricity of 0.00352, giving it a period of 96 minutes. The telescope's battery was accidentally overcharged and destroyed three days after the mission started. When attempts to communicate with the satellite — while its solar panels were illuminated by sunlight — failed, the $20 million project was abandoned. ABRIXAS decayed from orbit on 31 October 2017. The eROSITA telescope is based on the design of the ABRIXAS observatory. eROSITA was launched on board the Spektr-RG space observatory on 13 July 2019 from Baikonur to be deployed at the second Lagrange point (L2).
