Mikhailo Lomonosov (satellite)
Mikhailo Lomonosov (MVL-300, or Mikhailo, or more commonly Lomonosov; MVL stands for Mikhail Vasilyevich Lomonosov) is an astronomical satellite operated by Moscow State University (MSU) named after Mikhail Lomonosov. Mission The objective of the mission is the observation of gamma-ray bursts, high-energy cosmic rays and transient phenomena in the Earth's upper atmosphere. Launch The mission launch was initially planned for 2011 when 300 years since the birthday of Mikhail Lomonosov was celebrated. After several postponements the mission was finally launched on 28 April 2016 from Vostochny Cosmodrome by the Soyuz 2.1a launch vehicle. Scientific payload The spacecraft is equipped with seven scientific instruments: *Tracking Ultraviolet Set Up system (TUS) was designed to measure fluorescence light radiated by EAS (Extensive Air Showers) of Ultra High Energy Cosmic Rays (UHECR) in the Earth atmosphere as well as for transients' studies within UV-range. This was the first space b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Observatory
A space telescope or space observatory is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid the filtering and distortion ( scintillation) of electromagnetic radiation which they observe, and avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky (astronomical survey), and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth for satellite imaging, applied for weather analysis, espionage, and other types of information gathering.

Proton Detector
A proton is a stable subatomic particle, symbol , H+, or 1H+ with a positive electric charge of +1 ''e'' elementary charge. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as " nucleons" (particles present in atomic nuclei). One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force which binds the atomic electrons. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol ''Z''). Since each element has a unique number of protons, each element has its own unique atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element. The word ''proton'' is Greek for "first", and this name was giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spektr-RG
Spektr-RG (Russian: Спектр-РГ, ''Spectrum'' + '' Röntgen'' + ''Gamma''; also called Spectrum-X-Gamma, SRG, SXG) is a Russian–German high-energy astrophysics space observatory which was launched on 13 July 2019. It follows on from the Spektr-R satellite telescope launched in 2011. Background The original idea for this X-ray observatory satellite orbiting above Earth's atmosphere, which filters X-rays, was first proposed in the 1980s by Rashid Sunyaev of the Space Research Institute of the USSR Academy of Sciences. Twenty institutions from twelve countries came together to design a large observatory with five telescopes. However, after the collapse of the Soviet Union, the mission was abandoned due to cost-cutting from the Russian space program Roscosmos. The project was resurrected in 2003 with a scaled-down design. Overview The primary instrument of the mission is eROSITA, built by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany. It is des ...

Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.

Ultra-Fast Flash Observatory Pathfinder
The Ultra-Fast Flash Observatory (UFFO) Pathfinder is a space observatory measuring prompt emission of gamma-ray bursts (GRB) both in optical/UV and in X-ray range down to sub-second timescales for the first time. Instead of turning the whole satellite towards GRB location like the Swift Gamma-Ray Burst Mission (that takes about 100 seconds), UFFO employs a slewing mirror telescope approach – the optical path of the telescope is changed by rotation of motorized mirror within ~1 second after burst was detected. UFFO was launched April 28, 2016 on board the Mikhailo Lomonosov satellite during the first launch from the new Russian Vostochny Cosmodrome. Instruments UFFO Burst Alert & Trigger telescope (UBAT) UBAT is a wide-field coded mask X-ray camera. It has a 191 cm2 detecting area, 90.2°×90.2° field of view and is sensitive in the 15-150 keV photon energy range. UBAT is able to localize bursts with an accuracy of 7σ to a region 10 arcmin across in less than one seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamma-ray Bursts
In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. Bursts can last from ten milliseconds to several hours. After an initial flash of gamma rays, a longer-lived "afterglow" is usually emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, microwave and radio). The intense radiation of most observed GRBs is thought to be released during a supernova or superluminous supernova as a high-mass star implodes to form a neutron star or a black hole. A subclass of GRBs appear to originate from the merger of binary neutron stars. The sources of most GRBs are billions of light years away from Earth, implying that the explosions are both extremely energetic (a typical burst releases as much energy in a few seconds as the Sun will in its entire 10-billion-year lifetime) and extremely rare (a few per galaxy per million ...

Soyuz 2
Soyuz 2 (russian: Союз 2, Union 2) was an uncrewed spacecraft in the Soyuz family intended to be the target of a docking maneuver by the crewed Soyuz 3 spacecraft. It was intended to be the first docking of a crewed spacecraft in the Soviet space program. Although the two craft approached closely, the docking did not take place and the first successful Soviet docking of crewed spacecraft took place in the joint Soyuz 4 and Soyuz 5 mission. It served for the radio search and as a target vehicle for docking by the crewed Soyuz 3. Soyuz 2 soft-landed in a predetermined area of the Soviet Union. Mission parameters * Mass: * Perigee: * Apogee: * Inclination: 51.65° * Period: 88.50 minutes "Crew" hoax Conceptual artist Joan Fontcuberta claimed in 1997 that Soyuz 2 was crewed by Ivan Istochnikov and a dog named Kloka, who disappeared on 26 October 1968, with signs of having been hit by a meteorite. According to Fontcuberta, Soviet officials deleted Istochnikov from o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ria Novosti
RIA Novosti (russian: РИА Новости), sometimes referred to as RIAN () or RIA (russian: РИА, label=none) is a Russian state-owned domestic news agency. On 9 December 2013 by a decree of Vladimir Putin it was liquidated and its assets and workforce were transferred to the newly created Rossiya Segodnya agency. On 8 April 2014 RIA Novosti was registered as part of the new agency. RIA Novosti is headquartered in Moscow. The chief editor is Anna Gavrilova. Content RIA Novosti was scheduled to be closed down in 2014; starting in March 2014, staff were informed that they had the option of transferring their contracts to Rossiya Segodnya or sign a redundancy contract. On 10 November 2014, Rossiya Segodnya launched the Sputnik multimedia platform as the international replacement of RIA Novosti and Voice of Russia. Within Russia itself, however, Rossiya Segodnya continues to operate its Russian language news service under the name RIA Novosti with its ria.ru website. T ...

Cosmic Ray
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
