International Mars Exploration Working Group
The International Mars Exploration Working Group (IMEWG) is an organization of all major space agencies and institutions participating in the exploration of the planet Mars. Conceived in 1993, the working group meets twice per year to discuss an international strategy for the exploration of Mars. at atmos.washington.edu.

List Of Space Agencies
This is a list of government agencies engaged in activities related to outer space and space exploration. As of 2022, 77 different government space agencies are in existence, 16 of which have launch capabilities. Six government space agencies—the China National Space Administration (CNSA), the European Space Agency (ESA), the Indian Space Research Organisation (ISRO), the Japan Aerospace Exploration Agency (JAXA), the (US) National Aeronautics and Space Administration (NASA), and the Russian State Space Corporation "Roscosmos" — have full launch capabilities (ability to launch and recover multiple satellites, develop and deploy cryogenic rocket engines and operate space probes) and extraterrestrial landing capabilities. The name given is the English version, with the native language version below. The acronym given is the most common acronym: this can either be the acronym of the English version (e.g. JAXA), or the acronym in the native language. Where there are multiple ...

Space Exploration
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by robotic spacecraft, uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...
