Porosity of phobos
WebNov 17, 2015 · Long, thin "stretch marks" on the surface of Phobos are early signs that the Martian moon is falling apart, new research suggests. Phobos is a tiny moon that is closer to Mars than any other... WebJun 1, 2010 · Mass heterogeneities correspond to either an excess of porosity or a compaction of material under Stickney crater, or a deficit of porosity in the upper layers of Phobos, or a concentration of ice either in depth inside Phobos or in shallow layers. We then discretize the shape of Phobos using 500m-length cubes to fit its volume and total mass.

WebJul 23, 2024 · Phobos' density is too low to be pure rock, however, and it is known to have significant porosity. These results led to the suggestion that Phobos might contain a substantial reservoir of ice. Spectral observations have ruled out the presence of water on the surface. Phobos is highly nonspherical, with dimensions of 27 × 21.6 × 18.8 km.

WebFeb 1, 2014 · The second degree gravity field of Phobos ( C 20, C 22) could not be solved for at sufficient accuracy. The low bulk density suggests a high porosity and an inhomogeneous mass distribution but the large errors of C 20 and C 22 are still consistent with a homogeneous as well as an inhomogeneous mass distribution.
