23 wrz 2024 · A new map that details gravitational anomalies on Mars has revealed 20 mysteriously dense blobs, including a dog-shaped mass, buried below the planet's north pole.
orbital data of three spacecraft to map the gravity field of Mars. In this new map, low gravity canyons like Valles Marineris, in blue, stand out from the high-gravity reds and whites of the Tharsis mountains.
21 mar 2016 · A new map of Mars' gravity is the most detailed to date, providing a revealing glimpse into the planet's hidden interior. 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 Odyssey, and the Mars Reconnaissance Orbiter.
21 mar 2016 · 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. “Gravity maps allow us to see inside a planet, just as a doctor uses an X-ray to see inside a patient,” said Antonio Genova of the Massachusetts Institute of Technology (MIT ...
21 mar 2016 · 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.
22 mar 2016 · Scientists have used small fluctuations in the orbits of three NASA spacecraft to map the gravity field of Mars. If Mars were a perfectly smooth sphere of uniform density, the gravitational pull experienced by an orbiting spacecraft would be exactly the same everywhere on the planet.
21 mar 2016 · Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet mapping of Mars' crustal thickness (right).
