SHERLOC
Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is an ultraviolet Raman spectrometer that uses fine-scale imaging and an ultraviolet (UV) laser to determine fine-scale mineralogy, and detect organic compounds designed for the ''Perseverance'' rover as part of the Mars 2020 mission. It was constructed at the Jet Propulsion Laboratory with major subsystems being delivered from Malin Space Science Systems and Los Alamos National Laboratory. The Principal Investigator is Luther Beegle, and the Deputy Principal Investigator is Rohit Bhartia. SHERLOC has a calibration target with possible Mars suit materials, and it will measure how they change over time in the Martian surface environment. Goals According to a 2017 Universities Space Research Association (USRA) report: Construction There are three locations on the rover where SHERLOC components are located. The SHERLOC Turret Assembly (STA) is mounted at the end of the rover arm. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perseverance (rover)
''Perseverance'', nicknamed ''Percy'', is a car-sized Mars rover designed to explore the Jezero crater on Mars as part of NASA's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at 20:55 UTC. As of , ''Perseverance'' has been active on Mars for sols ( Earth days, or ) since its landing. Following the rover's arrival, NASA named the landing site Octavia E. Butler Landing. ''Perseverance'' has a similar design to its predecessor rover, ''Curiosity'', although it was moderately upgraded. It carries seven primary payload instruments, nineteen cameras, and two microphones. The rover also carried the mini-helicopter '' Ingenuity'' to Mars, an experimental aircraft and technology testbed that made the first powered flight on another planet on April 19, 2021. As of December 22, 2022, it has made 37 successful flights. '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rocks On Mars
This is an alphabetical list of named rocks (and meteorites) found on Mars, by mission. This list is a sampling of rocks viewed, and is not an exhaustive listing. A more complete listing may be found on the various NASA mission web sites. This listing does ''not'' include Martian meteorites found on Earth. Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than are not to be given official names. Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion. Often rocks are named after the children or family members of astronauts or NASA employees. The name ''Jazzy'', for example, was taken from a girl named Jazzy who grew up in Grand Junction, CO, USA. Her father worked for NASA and cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planetary Instrument For X-Ray Lithochemistry
Planetary Instrument for X-Ray Lithochemistry (PIXL) is an X-ray fluorescence spectrometer to determine the fine scale elemental composition of Martian surface materials designed for the ''Perseverance'' rover as part of the Mars 2020 mission. PIXL is manufactured and made by NASA Jet Propulsion Laboratory. Science objectives The scientific objectives of the instrument are the following: # Provide detailed geochemical assessment of past environments, habitability, and biosignature preservation potential. # Detect any potential chemical biosignatures that are encountered and characterize the geochemistry of any other types of potential biosignatures detected. # Provide a detailed geochemical basis for selection of a compelling set of samples for return to Earth.

Mars Suit
A Mars suit or Mars space suit is a space suit for EVAs on the planet Mars. Compared to a suit designed for space-walking in the near vacuum of low Earth orbit, Mars suits have a greater focus on actual walking and a need for abrasion resistance. Mars' surface gravity is 37.8% of Earth's, approximately 2.3 times that of the Moon, so weight is a significant concern, but there are fewer thermal demands compared to open space. At the surface the suits would contend with the atmosphere of Mars, which has a pressure of about . On the surface, radiation exposure is a concern, especially solar flare events, which can dramatically increase the amount of radiation over a short time. Some of the issues a Mars suit for surface operations would face include having enough oxygen for the person as the air is mostly carbon dioxide; in addition the air is also at a much lower pressure than Earth's atmosphere at sea level. Other issues include the Martian dust, low temperatures, and radiation. Ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars2020Rover-SHERLOC-20140731
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the 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 and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period and tilt o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
