The study published in the Geophysical Research Letters journal in August says the new findings were possible because of the gravity map of mars.
Its large (460-km-wide) and more subtle outer rim is difficult to see in images, but its red coloration makes it stand out in a gravity map.
The new gravity map will be helpful for future Mars exploration, because better knowledge of the planet's gravity anomalies helps mission controllers insert spacecraft more precisely into orbit about Mars.
The researchers fine-tuned their techniques in the initial development of an ultra-high resolution gravity map of Earth, for which they received multiple Australian Research Council grants.
A NASA mission called GRAIL sent two spacecraft to make a gravity map of the Moon.
In producing the best gravity map ever compiled of any planet or moon--Earth included--the mission illustrates how violently the moon's crust was pummeled by meteorites over eons.
Closer geological and structural observation (Figures 1 & 2) of this anomaly's axes suggested that its general trend followed an inferred granite intrusion area known as So'o granite The quite different nature of the Bouguer gravity map on the northern side was marked by gravity highs, bounded by relatively steep gradients occurring over or near higher metamorphic formations (granulite, migmatite and micaschist) and other granitic plutons, suggesting the existence of a suture zone between two of the crust's blocks (Kennedy, 1964).
The location of the event on the Bouguer gravity map of Kadri (1995) is shown in Fig.
The presence of these kinds of traps, whose existence can be established from a more detailed gravity map, will constitute prospects of oil and gas concentration.
To analyze the new gravity map, filtering the noise produced by erroneous or incomplete reductions (e.
The Estonian regional gravity map based on 4195 on-land gravity stations was converted from the Potsdam gravity system into the IGSN 71 gravity system.
A gravimetric and a derived gravity map of the wider area of Roznov pod Radhostem have been compiled in order to analyse the geology of the Silesian nappe, and reflection seismic profiles 221/77, 221A/80, 221B/79 and 221C/80 have been used to refine the interpretations.
