where G is the universal constant of gravitation (commonly taken as G = 6.674 × 10 −11 m 3 kg −1 s −2), [10] M is the mass of Mars (most updated value: 6.41693 × 10 23 kg), [11] m is the mass of the satellite, r is the distance between Mars and the satellite, and is the angular velocity of the satellite, which is also equivalent to (T ...
The atmosphere of Mars has been losing mass to space since the planet's core slowed down, and the leakage of gases still continues today. [ 4 ] [ 8 ] [ 9 ] The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature , which is about 210 K (−63 °C ...
The holiday was founded by the Smålander Jonas Svenningson, who was amused by the way his aunt, who had a particularly strong local accent, referred to 1 March as fössta mass. Building on this, he added tossdan (the Småland pronunciation of torsdagen , 'the Thursday') to create the phrase fössta tossdan i mars , and in February 2010 he ...
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.
The Phobos monolith (right of center, casting long shadow) as taken by the Mars Global Surveyor (MOC Image 55103, 1998). The location of the monolith (HiRISE image PIA10368) The Phobos monolith is a large rock on the surface of Mars' moon Phobos. [1] It is a boulder, about 85 m (279 ft) across and 90 m (300 ft) tall.
Olympus Mons (/ ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ-/; [4] Latin for 'Mount Olympus') is a large shield volcano on Mars.It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level.

where M is the total mass of the two bodies and k 2 is Moulton's notation for the gravitational constant. He defines c 1 , c 2 , and c 4 to be other constants of the motion. The notation C 3 probably became popularized via the JPL technical report TR-32-30 ("Design of Lunar and Interplanetary Ascent Trajectories", Victor C. Clarke, Jr., March ...
