Timeline Of Mars Science Laboratory
The Mars Science Laboratory and its rover, Curiosity rover, ''Curiosity'', were launched from Earth on 26 November 2011. As of , , ''Curiosity'' has been in Gale Crater on the Mars, planet Mars for Sol (day on Mars), sols ( days, total days; ') since landing on 6 August 2012. ''(See Timeline of Mars Science Laboratory#Current status, 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 14 December 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 cont ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

Curiosity (rover)
''Curiosity'' is a car-sized Mars rover Space exploration, exploring Gale (crater), Gale crater and Mount Sharp on Mars as part of NASA's Mars Science Laboratory (MSL) mission. ''Curiosity'' was launched from Cape Canaveral Space Force Station, Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 Coordinated Universal Time, UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than from the center of the rover's touchdown target after a journey. Mission #Goals and objectives, goals include an investigation of the Martian climate of Mars, climate and geology of Mars, geology, an assessment of whether the selected field site inside Gale has ever offered environmental science, environmental conditions favorable for Life on Mars, microbial life (including investigation of the Water on Mars, role of water), and planetary habitability studies in preparation for Human mission to Mars, human exploration.

HiRISE
High Resolution Imaging Science Experiment is a camera on board the '' Mars Reconnaissance Orbiter'' which has been orbiting and studying Mars since 2006. The 65 kg (143 lb), US$40 million instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5m (19.7 in) aperture reflecting telescope, the largest so far of any deep space mission, which allows it to take pictures of Mars with resolutions of 0.3m/pixel (1ft/pixel), resolving objects below a meter across. HiRISE has imaged Mars exploration rovers on the surface, including the ''Opportunity'' rover and the ongoing ''Curiosity'' mission. History In the late 1980s, of Ball Aerospace & Technologies began planning the kind of high-resolution imaging needed to support sample return and surface exploration of Mars. In early 2001 he teamed up with Alfred McEwen of the University of Arizona to propose such ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

Hazcam
Hazcams (short for hazard avoidance cameras) are photographic cameras mounted on the front and rear of NASA's ''Spirit'', ''Opportunity'', ''Curiosity'' and ''Perseverance'' rover missions to Mars and on the lower front portion of Chinese ''Yutu'' rover mission to the Moon. Overview The ''Curiosity'' rover's hazcams are sensitive to visible light and return black and white images of resolution 1024 × 1024 pixels."Hazard Avoidance Camera (Hazcam)". PDS Geosciences Node. Retrieved September 4, 2019. These images are used by the rovers' internal computer to autonomously navigate around hazards. Due to their positioning on both sides of the rovers, simultaneous images taken by either both front or both rear cameras can be used to produce a [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

NBC News
NBC News is the news division of the American broadcast television network NBC. The division operates under NBCUniversal Media Group, a division of NBCUniversal, which is itself a subsidiary of Comcast. The news division's various operations report to the president of NBC News, Rebecca Blumenstein. The NBCUniversal News Group also comprises MSNBC, the network's 24-hour liberal cable news channel, as well as business and consumer news channels CNBC and CNBC World, the Spanish language and United Kingdom-based Sky News. NBC News aired the first regularly scheduled news program in American broadcast television history on February 21, 1940. The group's broadcasts are produced and aired from 30 Rockefeller Plaza, NBCUl's headquarters in New York City. The division presides over the flagship evening newscast ''NBC Nightly News'', the world's first of its genre morning television program, ''Today (American TV program), Today'', and the longest-running television series in American hi ...

Bradbury Landing
Bradbury Landing is the August 6, 2012, landing site within Gale (crater), Gale crater on planet Mars of the Mars Science Laboratory (MSL) Curiosity rover, ''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 si ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. 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. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ...

Health Threat From Cosmic Rays
Astronauts are exposed to approximately 72 millisieverts (mSv) while on six-month-duration missions to the International Space Station (ISS). Longer 3-year missions to Mars, however, have the potential to expose astronauts to radiation in excess of 1000 mSv. Without the protection provided by Earth's magnetic field, the rate of exposure is dramatically increased. The risk of cancer caused by ionizing radiation is well documented at radiation doses beginning at 100 mSv and above. Related radiological effect studies have shown that survivors of the atomic bomb explosions in Hiroshima and Nagasaki, nuclear reactor workers and patients who have undergone therapeutic radiation treatments have received low-linear energy transfer (LET) radiation (x-rays and gamma rays) doses in the same 50-2,000 mSv range. Composition of space radiation While in space, astronauts are exposed to radiation which is mostly composed of high-energy protons, helium nuclei (alpha particles), and hi ...
