MetNet
Mars MetNet is a planned atmospheric science mission to Mars, initiated by the Finnish Meteorological Institute (FMI) and under development by Finland, Russia and Spain. By September 2013, two flight-capable entry, descent and landing systems (EDLS) have been manufactured and tested. As of 2015 baseline funding exists until 2020. As of 2016, neither the launch vehicle nor precursory launch date have been set. The objective is to establish a widespread surface observation network on Mars to investigate the planet's atmospheric structure, physics and meteorology. The bulk of the mission consist of at least 16 MetNet impact landers deployed over the Martian surface. History The basic concepts of Mars MetNet were initiated by the Finnish Meteorological Institute (FMI) team in late 1980s. The concept was matured over a decade, and eventually the development work started in the year 2000. MetNet can be considered as a successor of the NetLander, Russian Mars 96 and the earlier ESA Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exploration Of Mars
The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, ''Spirit'' and ''Opportunity'' which operated for years beyond their specification. Current status , there are three operational rovers on the surface of Mars, the ''Curiosity'' and ''Perseverance'' rovers, both operated by the United States of America space agency NASA, as well as the ''Zhurong'' rover, part of the ''Tianwen-1'' mi ...

NetLander
In late 2007 (or 2009) CNES (the French Space Agency) and ESA (the European Space Agency) had planned to send a remote sensing orbiter and four small Netlanders to Mars. They planned to land them in four different locations. The CNES and ESA cancelled this mission because it was too expensive; both agencies planned to send other orbiters and landers for missions like ExoMars. The Landers' mission was to take pictures of the landing site and explore Mars' internal surface and atmosphere. Each of the four landers was to carry instruments for the following measurements: * Seismometer, IPG, France * Panoramic camera, DLR, Germany * Atmospheric sensors, FMI, Finland * Atmospheric electricity sensor, CETP, France * geodesic and ionospheric measurements, GRGS, France * Soil properties measurements, University of Münster, Germany * Ground Penetrating Radar, CETP, France * Magnetometer, CETP, France * Microphone, University of California, Berkeley, USA The Orbiter's mission was to take ...

Phobos Grunt
Fobos-Grunt or Phobos-Grunt (russian: link=no, Фобос-Грунт, where ''грунт'' refers to the ''ground'' in the narrow geological meaning of any type of soil or rock exposed on the surface) was an attempted Russian sample return mission to Phobos, one of the moons of Mars. Fobos-Grunt also carried the Chinese Mars orbiter Yinghuo-1 and the tiny Living Interplanetary Flight Experiment funded by the Planetary Society. It was launched on 8 November 2011, at 20:16 UTC, from the Baikonur Cosmodrome, but subsequent rocket burns intended to set the craft on a course for Mars failed, leaving it stranded in low Earth orbit. Efforts to reactivate the craft were unsuccessful, and it fell back to Earth in an uncontrolled re-entry on 15 January 2012, over the Pacific Ocean, west of Chile. The return vehicle was to have returned to Earth in August 2014, carrying up to of soil from Phobos. Funded by the Russian Federal Space Agency and developed by Lavochkin and the Russian Spa ...

Finnish Meteorological Institute
The Finnish Meteorological Institute (FMI; fi, Ilmatieteen laitos; sv, Meteorologiska institutet) is the government agency responsible for gathering and reporting weather data and forecasts in Finland. It is a part of the Ministry of Transport and Communications but it operates semi-autonomously. The Institute is an impartial research and service organisation with expertise covering a wide range of atmospheric science activities other than gathering and reporting weather data and forecasts. The headquarters of the Institute is in Kumpula Campus, Helsinki, Finland. Services FMI provides weather forecasts for aviation, traffic, shipping and media as well as private citizens via internet and mobile devices. It also has air quality services. For sea areas, it provides information about ice cover, sea level changes and waves. In 2013 FMI made openly available data sets such as weather, sea and climate observation data, time series and model data. The open data is targeted to b ...

Climate Of Mars
The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be directly observed in detail from the Earth with help from a telescope. Although Mars is smaller than the Earth, 11% of Earth's mass, and 50% farther from the Sun than the Earth, its climate has important similarities, such as the presence of polar ice caps, seasonal changes and observable weather patterns. It has attracted sustained study from planetologists and climatologists. While Mars' climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. Mars' atmosphere has a scale height of approximately , 60% greater than that on Earth. The climate is of considerable relevance to the question of whether life is or ever has been present on the planet. The climate briefly received more interest in the news due to NASA measurements indicating increased sublima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars 96
Mars 96 (sometimes called Mars-8) was a failed Mars mission launched in 1996 to investigate Mars by the Russian Space Forces and not directly related to the Soviet Mars probe program of the same name. After failure of the second fourth-stage burn, the probe assembly re-entered the Earth's atmosphere, breaking up over a long portion of the Pacific Ocean, Chile, and Bolivia. The ''Mars 96'' spacecraft was based on the Phobos probes launched to Mars in 1988. They were of a new design at the time and both ultimately failed. For the ''Mars 96'' mission the designers believed they had corrected the flaws of the Phobos probes, but the value of their improvements was never demonstrated due to the destruction of the probe during the launch phase. History Mars 96, the only Soviet/Russian lunar or planetary probe in the 1990s, was an ambitious mission to investigate the evolution of the Martian atmosphere, its surface, and its interior. Originally planned as two spacecraft, Mars 94 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Shield
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

ExoMars
ExoMars (Exobiology on Mars) is an astrobiology programme of the European Space Agency (ESA). The goals of ExoMars are to search for signs of past life on Mars, investigate how the Martian water and geochemical environment varies, investigate atmospheric trace gases and their sources and by doing so demonstrate the technologies for a future Mars sample-return mission. The first part of the programme is a mission launched in 2016 that placed the Trace Gas Orbiter into Mars orbit and released the ''Schiaparelli'' EDM lander. The orbiter is operational but the lander crashed on the planet's surface. The second part of the programme was planned to launch in July 2020, when the ''Kazachok'' lander would have delivered the ''Rosalind Franklin'' rover on the surface, supporting a science mission that was expected to last into 2022 or beyond. On 12 March 2020, it was announced that the second mission was being delayed to 2022 as a result of problems with the parachutes, which could ...
