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 ...

2016年12月19日 · These proportionalities can be expressed by the formula g = m/r 2, where g is the surface gravity of Mars (expressed as a multiple of the Earth's, which is 9.8 m/s²), m is its mass –...

2016年12月16日 · Martian gravity is roughly 38% that of Earth's, a fact that will have serious implications for crewed missions and even colonization efforts.

2024年10月3日 · *Mean orbital distance from the center of Mars. Notes on the factsheets - definitions of parameters, units, notes on sub- and superscripts, etc. Planetary Fact Table - metric units

The analysis and processing of MGS, Mars Odyssey, and MRO data allowed us to recover the static gravity field of Mars in spherical harmonics to degree and order 120, named Goddard Mars Model-3 (GMM-3), which is available from the Geosciences Node of the Planetary Data System .

1999年10月1日 · Mars' gravitational potential, or areoid (Fig. 1B), displays two hemispheric-scale quasi-circular features with a dynamic range of more than 2 km, an order of magnitude greater than that observed for Earth. The Tharsis Montes, Olympus Mons, Valles Marineris, and Isidis impact basin are resolved as individual gravitational anomalies in the areoid.

2016年3月21日 · A new map of Mars’ gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. The map was derived using Doppler and range tracking data collected by NASA’s Deep Space Network from three NASA spacecraft in orbit around Mars: Mars Global Surveyor, Mars ...

2016年3月21日 · Goddard Mars Model (GMM) 3 is a global map of the gravity field of Mars. It was created by studying the flight paths of three Mars-orbiting spacecraft — Mars Global Surveyor (MGS), Mars Odyssey (ODY), and Mars Reconnaissance Orbiter (MRO).

2016年3月21日 · A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. Satellites always orbit a planet's center of mass, but can be pulled slightly off course by the gravity of massive features like Olympus Mons, the solar system's tallest mountain.

The average gravitational acceleration on Mars is 3.72076 m/s², which is 62% lower than the 9.8 m/s² gravity of Earth. It means a thing of 100 pounds mass on Earth would have only 38 pounds mass on Mars. If a person jumps on the Mars surface, it would be 2.6 times higher than on Earth.
