Porosity of phobos
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. WebThe polar body, with haploid DNA, is a small cell produced during the meiosis of an oocyte. Here, we describe the detailed procedures for the detection of the second polar body in …

Phobos has a near-surface porosity of at least 40%, so it seems impossible to sustain 2/5.
WebFeb 1, 2007 · Phobos may have few particles smaller than 30 μm, while Deimos can have particles down to ∼ 15 μm. 20 μm grains are small enough for electrostatic repulsion to possibly become significant enough to increase regolith porosity. Also, Deimos re-accretes any dust grains more efficiently than Phobos. Webcorresponding range of the body’s porosity (30% ± 5%), provide a basis for improved interpretation of the internal structure. We conclude that the interior of Phobos likely contains large voids. When applied to various hypotheses bearing on the origin of Phobos, these results are inconsistent with the proposition that Phobos is a captured ...
