For the lunar gravity field, it is conventional to use an equatorial radius of R = 1738.0 km. The gravity potential is written with a series of spherical harmonic functions P nm. The gravitational potential V at an external point is conventionally expressed as positive in astronomy and geophysics, but negative in physics. Then, with the former ...
Combining gravity and Lunar Laser Ranging data gives the 3 principal moments of inertia. [44] The moments indicate that a dense core is small. Combining gravity and lunar Topography, 74 circular impact basins were identified. [45] Strong increases in gravity that are associated with circular impact basins are mascons discovered by Muller and ...
The main lunar gravity features are mascons, large positive gravitational anomalies associated with some of the giant impact basins, partly caused by the dense mare basaltic lava flows that fill those basins. [83] [84] The anomalies greatly influence the orbit of spacecraft about the Moon. There are some puzzles: lava flows by themselves cannot ...
English: This image shows the variations in the lunar gravity field as measured by NASA's Gravity Recovery and Interior Laboratory (GRAIL) during the primary mapping mission from March to May 2012. Very precise microwave measurements between two spacecraft, named Ebb and Flow, were used to map gravity with high precision and high spatial ...
The New Shepard mission is far from the first to carry scientific payloads to the edge of space, but it was the first to mimic the moon's gravity.. The gravitational pull of the lunar surface is ...
A visualization of the lunar gravity field based on spherical harmonic coefficients determined from Lunar Prospector data. The left side of the image shows the far side of the Moon where the increased uncertainty in the gravity field can be seen. The Doppler Gravity Experiment (DGE) was the first polar, low-altitude mapping of the lunar gravity ...
Topography (top) and corresponding gravity (bottom) signal of Mare Smythii on the Moon containing a significant mascon. Map of the Moon's gravity anomalies. In astronomy, astrophysics and geophysics, a mass concentration (or mascon) is a region of a planet's or moon's crust that contains a large positive gravity anomaly.
The Krechet-94 (Russian Кречет, meaning gyrfalcon) is a space suit model developed for lunar excursion during the Soviet crewed lunar program. It was designed by NPP Zvezda. Development began in 1967, concurrently with the Orlan suit for microgravity spacewalks. The developmental model was known simply as Krechet. [1]
