Squalane is the organic compound with the formula ((CH 3) 2 CH(CH 2) 3 CH(CH 3)(CH 2) 3 (CH 2) 3 CH(CH 3)(CH 2) 2) 2. A colorless hydrocarbon, it is the hydrogenated derivative of squalene, although commercial samples are derived from nature. [3] In contrast to squalene, due to the complete saturation of squalane, it is not subject to auto ...

[36] [37] Although the organic carbon was probably from Mars, it can all be explained by dust and meteorites that have landed on the planet. [38] [39] [40] Because much of the carbon was released at a relatively low temperature in Curiosity's Sample Analysis at Mars (SAM) instrument package, it probably did not come from carbonates in the ...
Mars-1 was the first spacecraft launched to Mars in 1962, [266] but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of ...
Chemical analysis suggests that it originated on Mars [6] [7] when there was liquid water on the planet's surface. [ 8 ] [ 9 ] In September 2005, Vicky Hamilton, of the University of Hawaii at Manoa , presented an analysis of the origin of ALH84001 using data from the Mars Global Surveyor and 2001 Mars Odyssey spacecraft orbiting Mars.
The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
Mars’s orbit is much more elliptical—with an aphelion, or furthest remove from the sun, of 155 million miles and a perihelion, or closest approach, of 128 million miles.
A transit of Mercury from Mars took place on January 12, 2005 from about 14:45 UTC to 23:05 UTC, but camera resolution did not permit seeing Mercury's 6.1" angular diameter. Transits of Deimos across the Sun were seen, but at 2' angular diameter, Deimos is about 20 times larger than Mercury's 6.1" angular diameter.
