Venera 7
Venera 7 () was a Soviet spacecraft, part of the Venera series of probes to Venus. When it landed on the Venusian surface on 15 December 1970, it became the first spacecraft to soft land on another planet and the first to transmit data from there back to Earth. Design The lander was designed to be able to survive pressure of up to and temperatures of . This was much greater than what was expected to be encountered but significant uncertainties as to the surface temperatures and pressure of Venus resulted in the designers opting for a large margin of error. This degree of hardening limited the amount of mass available for scientific instruments both on the probe itself and the interplanetary bus. The interplanetary bus carried a solar-wind charged-particle detector and a cosmic-ray detector. On the lander were temperature and pressure sensors as well as an accelerometer to measure atmospheric density. The probe also carried a radar altimeter. Launch The probe was launched f ...

Sergei Pavlovich Korolyov Museum Of Cosmonautics
The Serhiy Pavlovych Korolyov Museum of Cosmonautics () is a technology museum in Zhytomyr, Ukraine, dedicated to Sergei Korolev, Serhiy Korolyov. Korolyov led the Sputnik project and was chief engineer for the Soviet Union's rocket and space program from the late 1950s until his death in 1966. He was born in Zhytomyr, then part of the Russian Empire. In 1970, the house in which Korolyov was born was dedicated as a memorial to him, a campus of the Zhytomyr Regional Museum. The museum achieved independent status in 1987, and the present museum building was constructed in 1991. The museum houses around 11,000 exhibits related to rocket and space exploration, including the Soyuz 27 descent module, a small sample of lunar soil, full-size replicas of a complete Soyuz (spacecraft), Soyuz spacecraft, the Vostok 1 descent module, and the Lunokhod 2 lunar rover. From 2013, 2.5 million visitors have passed through the museum's doors. Next to the exposition space, a rocket launches a g ...

Accelerometer
An accelerometer is a device that measures the proper acceleration of an object. Proper acceleration is the acceleration (the rate of change (mathematics), rate of change of velocity) of the object relative to an observer who is in free fall (that is, relative to an inertial frame of reference). Proper acceleration is different from coordinate acceleration, which is acceleration with respect to a given coordinate system, which may or may not be accelerating. For example, an accelerometer at rest on the surface of the Earth will measure an Gravitational acceleration, acceleration due to Earth's gravity straight upwards of about Standard gravity, ''g'' ≈ 9.81 m/s2. By contrast, an accelerometer that is in free fall will measure zero acceleration. Accelerometers have many uses in industry, consumer products, and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. In unmanned aerial vehicles, accelerometers help to stabili ...

Springer New York
Springer Publishing Company is an American publishing company of academic journals and books, focusing on the fields of nursing, gerontology, psychology, social work, counseling, public health, and rehabilitation (neuropsychology). It was established in 1951 by Bernhard Springer, a great-grandson of Julius Springer, and is based in Midtown Manhattan, New York City. History Springer Publishing Company was founded in 1950 by Bernhard Springer, the Berlin-born great-grandson of Julius Springer, who founded Springer-Verlag (now Springer Science+Business Media). Springer Publishing's first landmark publications included ''Livestock Health Encyclopedia'' by R. Seiden and the 1952 ''Handbook of Cardiology for Nurses''. The company's books soon branched into other fields, including medicine and psychology. Nursing publications grew rapidly in number, as Modell's ''Drugs in Current Use'', a small annual paperback, sold over 150,000 copies over several editions. Solomon Garb's ''Laborator ...

Reefed
Reefing reduces the area of a sail, usually by folding or rolling one edge of the canvas in on itself and attaching the unused portion to a spar or a , as the primary measure to preserve a sailing vessel's stability in strong winds. Restoring full sail area is termed ''shaking out'' a . Whereas fore-and-aft rigged vessels store the unused portion of the sail on a boom (below the sail), square-rigged vessels stow the unused portion on a spar above the sail. Reefing may occur by rolling the sail around its luff or foot, either on a rotating stay or within a spar. Fore-and-aft rigs Sails may have built-in alternative attachment points that allow their area to be reduced. In a mainsail, reefing cringles may be installed in the sail; a cruising boat will typically have two to three pairs. These are pulled down to the boom to form a new tack and clew, reducing the sail's area. The first pair closest to the boom is called a single reef, the next pair is called a double reef, ...

Atmosphere Of Venus
The atmosphere of Venus is the very dense layer of gases surrounding the planet Venus. Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen, with other chemical compounds present only in trace amounts. It is much denser and hotter than atmosphere of Earth, that of Earth; the temperature at the surface is 740 Kelvin, K (467 °C, 872 °F), and the pressure is , roughly the pressure found under water on Earth. The atmosphere of Venus supports decks of opaque clouds of sulfuric acid that cover the entire planet, preventing optics, optical Earth-based and orbital observation of the surface. Information about surface topography has been obtained exclusively by radar imaging. Aside from the very surface layers, the atmosphere is in a state of vigorous circulation. The upper layer of troposphere exhibits a phenomenon of Atmospheric super-rotation, super-rotation, in which the atmosphere circles the planet in just four Earth days, much faster than the p ...
