Pioneer Venus Multiprobe
The Pioneer Venus Multiprobe, also known as Pioneer Venus 2 or Pioneer 13, was a spacecraft launched in 1978 to explore Venus as part of NASA's Pioneer program. This part of the mission included a Satellite bus, spacecraft bus which was launched from Earth. The bus carried one large and three smaller probes, which, after separating, each penetrated the Venusian atmosphere at a different location, returning data as they descended into the planet's thick atmosphere. The entries occurred on December 9, 1978. In context There was also an orbiter launched in 1978, part of the overall Pioneer Venus project along with this entry probe mission. Whereas the probes entered the atmosphere in 1978, the Pioneer Venus Orbiter would stay in orbit throughout the 1980s and the early 1990s. The next major mission was the Magellan (spacecraft), ''Magellan'' spacecraft, which was an orbiter capable of mapping Venus by seeing through its opaque clouds with radar.

Water On Mars
Although very small amounts of liquid water may occur transiently on the surface of Mars, limited to traces of dissolved moisture from the atmosphere and thin films, large quantities of ice are present on and under the surface. Small amounts of water vapor are present in the atmosphere, and liquid water may be present under the surface. In addition, a large quantity of liquid water was likely present on the surface in the distant past. Currently, ice is mostly present in polar permafrost. More than 5 million km3 of ice have been detected at or near the surface of Mars, enough to cover the planet to a depth of . Even more ice might be locked away in the deep subsurface.Carr, 2006, p. 173. The chemical signature of water vapor on Mars was first unequivocally demonstrated in 1963 by spectroscopy using an Earth-based telescope. In 2008 and 2013, ice was detected in soil samples taken by the Phoenix lander and ''Curiosity'' rover. In 2018, radar findings suggested the pre ...

Solar Panel
A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in battery (electricity), batteries. Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems. A photovoltaic system consists of one or more solar panels, an solar inverter, inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as charge controller, controllers, Measuring instrument, meters, and solar tracker, trackers. Most panels are in solar farms or Rooftop solar power, rooftop solar panels which grid-connected photovoltaic system, supply the electricity grid. Some advantages of solar panels are ...

Beagle 2
The ''Beagle 2'' was an inoperative British Mars lander that was transported by the European Space Agency's 2003 ''Mars Express'' mission. It was intended to conduct an astrobiology mission that would have looked for evidence of past life on Mars. The spacecraft was successfully deployed from the ''Mars Express'' on 19 December 2003 and was scheduled to land on the surface of Mars on 25 December. ESA, however, received no communication from the lander at its expected landing time on Mars, and declared the mission lost in February 2004 after numerous attempts to contact the spacecraft were made. The ''Beagle 2'' fate remained a mystery until January 2015, when it was located on the surface of Mars in a series of images from NASA's '' Mars Reconnaissance Orbiter'' HiRISE camera. The images showed it landed safely but two of its four solar panels failed to deploy, blocking the spacecraft's communications antenna. The ''Beagle 2'' is named after , the ship that took the naturalis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soft Landing (aeronautics)
A soft landing is any type of aircraft, rocket or lander (spacecraft), spacecraft landing that does not result in significant damage to or destruction of the vehicle or its payload, as opposed to a hard landing. The average vertical speed in a soft landing should be about per second or less. A soft landing can be achieved by * Parachute—often this is Splashdown, into water. * Vertical rocket power using retrorockets, often referred to as VTVL (vertical landing referred to as VTOL, is usually for aircraft landing in a level attitude, rather than rockets) — first achieved on a suborbital trajectory by Bell Rocket Belt and on an orbital trajectory by the Surveyor 1. * Horizontal landing, most aircraft and some spacecraft, such as the Space Shuttle, land this way accompanied with a parachute. * Being caught in midair, as done with Corona (satellite), Corona spy satellites and followed by some other form of Takeoff and landing, landing. * Reducing landing speed by impact wit ...
