Timeline Of Mars Science Laboratory
The Mars Science Laboratory and its rover, ''Curiosity'', were launched from Earth on November 26, 2011. As of , , ''Curiosity'' has been on the planet Mars for sols ( total days; ') since landing on August 6, 2012. ''(See Current status.)'' Prelaunch (2004–2011) In April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for the Mars Science Laboratory and rover mission. Launch was proposed for September 2009. By December 14, 2004, eight proposals were selected, including instruments from Russia and Spain. Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15 to 100 percent thrust with a fixed propellant inlet pressure. By November 2008 most hardware and software development was complete, and testing continued. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gale Crater
Gale is a crater, and probable dry lake, at in the northwestern part of the Aeolis quadrangle on Mars. It is in diameter and estimated to be about 3.5–3.8 billion years old. The crater was named after Walter Frederick Gale, an amateur astronomer from Sydney, Australia, who observed Mars in the late 19th century. Aeolis Mons is a mountain in the center of Gale and rises high. Aeolis Palus is the plain between the northern wall of Gale and the northern foothills of Aeolis Mons. Peace Vallis, a nearby outflow channel, 'flows' down from the hills to the Aeolis Palus below and seems to have been carved by flowing water. Several lines of evidence suggest that a lake existed inside Gale shortly after the formation of the crater. The NASA Mars rover ''Curiosity'', of the Mars Science Laboratory (MSL) mission, landed in "Yellowknife" ''Quad 51'' of Aeolis Palus in Gale at 05:32 UTC August 6, 2012. NASA named the landing location Bradbury Landing on August 22, 2012. ''Curiosity' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradbury Landing
Bradbury Landing is the August 6, 2012, landing site within Gale crater on planet Mars of the Mars Science Laboratory (MSL) ''Curiosity'' rover. On August 22, 2012, on what would have been his 92nd birthday, NASA named the site for author Ray Bradbury, who had died on June 5, 2012. The coordinates of the landing site on Mars are: . The rover drove away from this specific landing location in the summer of 2012, but because of the nature of landing there is no actual lander there. The track prints and blast marks are slowly blowing away in the Martian wind, as recorded by Mars orbiters. Description Gale Crater was the MSL landing site in 2012. Within Gale Crater is a mountain, named Aeolis Mons ("Mount Sharp"), of layered rocks, rising about above the crater floor, that ''Curiosity'' will investigate. The landing site is a smooth region in "Yellowknife" ''Quad 51'' of Aeolis Palus inside the crater in front of the mountain. The target landing site location was an elliptical ...

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Health Threat From Cosmic Rays
Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, but space radiation health risks also occur for missions in low Earth orbit such as the International Space Station (ISS). In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars. The deep-space radiation environment The radiation environment of deep space is different from that on the Earth's surface or in low Earth orbit, due to the much larger flux of high-energy galactic cosmic rays (GCRs), along with radiation from solar proton events (SPEs) and the radiation belts. Galactic cosmic rays (GCRs) consist of high energy protons (85%), alpha particles (14%) and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlas V 541 Into The Flight
An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a region of Earth. Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it. Etymology The use of the word "atlas" in a geographical context dates from 1595 when the German-Flemish geographer Gerardus Mercator published ("Atlas or cosmographical meditations upon the creation of the universe and the universe as created"). This title provides Mercator's definition of the word as a description of the creation and form of the whole universe, not simply as a collection of maps. The volume that was published posthumously one year after his death is a wide-ranging text but, as the editions evolved, it became simply a collection of maps and it ...
