  2. Atmosphere of Mars - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Mars

    Hydrodynamic escape in the early history of Mars may explain the isotopic fractionation of argon and xenon. On modern Mars, the atmosphere is not leaking these two noble gases to outer space owing to their heavier mass. However, the higher abundance of hydrogen in the Martian atmosphere and the high fluxes of extreme UV from the young Sun ...

  3. Composition of Mars - Wikipedia

    en.wikipedia.org/wiki/Composition_of_Mars

    Mars is differentiated, which—for a terrestrial planet—implies that it has a central core made up of high density matter (mainly metallic iron and nickel) surrounded by a less dense, silicate mantle and crust. [4] Like Earth, Mars appears to have a molten iron core, or at least a molten outer core. [5]

  4. Xenon - Wikipedia

    en.wikipedia.org/wiki/Xenon

    To prevent decomposition, the xenon tetroxide thus formed is quickly cooled into a pale-yellow solid. It explodes above −35.9 °C into xenon and oxygen gas, but is otherwise stable. A number of xenon oxyfluorides are known, including XeOF 2, XeOF 4, XeO 2 F 2, and XeO 3 F 2. XeOF 2 is formed by reacting OF 2 with xenon gas at

    Compared with solar xenon, Earth's atmospheric Xe is enriched in heavy isotopes by 3 to 4% per atomic mass unit (amu). [18] However, the total abundance of xenon gas is depleted by one order of magnitude relative to other noble gases. [15] The elemental depletion while relative enrichment in heavy isotopes is called the "Xenon paradox".

    Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.

    Click on image to see more. Note how close the orbit of Mars is to the asteroid belt. Besides heat generated by molten rock, Mars has had much heat produced when asteroids impacted its surface making giant craters. The area around a large impact may take hundreds of thousands of years to cool. [4] 243 Ida and its moon Dactyl. Dactyl is the ...
