The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. "Hottah" rock outcrop on Mars – ancient streambed [1] [2][3] viewed by the Curiosity Rover (September 12, 2012, white balanced) (raw, close-up, 3-D version). Abundant iron compounds are responsible for the bright brownish-red colour ...
Selenium is a chemical element; it has the symbol Se and atomic number 34. It has various physical appearances, including a brick-red powder, a vitreous black solid, and a grey metallic-looking form. It seldom occurs in this elemental state or as pure ore compounds in Earth's crust.
The isotope selenium-75 has radiopharmaceutical uses. For example, it is used in high-dose-rate endorectal brachytherapy, as an alternative to iridium-192. [8]In paleobiogeochemistry, the ratio in amount of selenium-82 to selenium-76 (i.e, the value of δ 82/76 Se) can be used to track down the redox conditions on Earth during the Neoproterozoic era in order to gain a deeper understanding of ...
It should also be denser than polonium (α-Lv: 12.9 g/cm 3; α-Po: 9.2 g/cm 3); like polonium it should also form an α and a β allotrope. [ 4 ] [ 96 ] The electron of a hydrogen-like livermorium atom (oxidized so that it only has one electron, Lv 115+ ) is expected to move so fast that it has a mass 1.86 times that of a stationary electron ...
Deimos (moon) Deimos / ˈdaɪməs / (systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]
SHERLOC's calibration target aboard the Perseverance Mars rover with Mars Meteorite in the centre of top row. 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 ...
The InSight mission to Mars launched with a C 3 of 8.19 km 2 /s 2. [2] The Parker Solar Probe (via Venus) plans a maximum C 3 of 154 km 2 /s 2. [3] Typical ballistic C 3 (km 2 /s 2) to get from Earth to various planets: Mars 8-16, [4] Jupiter 80, Saturn or Uranus 147. [5] To Pluto (with its orbital inclination) needs about 160–164 km 2 /s 2.

An areostationary orbit, areosynchronous equatorial orbit (AEO), or Mars geostationary orbit is a circular areosynchronous orbit (ASO) approximately 17,032 km (10,583 mi) in altitude above the Mars equator and following the direction of Mars's rotation. An object in such an orbit has an orbital period equal to Mars's rotational period, and so ...
