In the 1960s, Dr Ernst Steinhoff and Dr Fred Singer stated the potential of the Martian moons as subjects for space exploration. An examination of the Martian satellites could. This Viking 2 Orbiter image shows the surface of Mars’ moon Deimos from a distance of 30 km.
29 lis 2021 · For example, how were Deimos and Phobos produced? Where are their geological histories similar, and where do they diverge? Why are the global densities of Deimos and Phobos different from each other, and why are these densities less than typical rocky bodies?
Basic Properties of Phobos and Deim (Cont.) Mars is blessed with two natural space stations, enabling teleoperations on the surface, eliminating comm delays of up to 40 min round-trip .. Mars dominates the sky on Phobos, blocking solar and cosmic radiation from that direction
Phobos is the larger of the two moons of Mars, with a mean diameter 2 of about 22 km and an orbital radius of 9,376 km. Phobos orbits faster than Mars rotates, so it rises in the west and sets in the east as viewed from the planet’s surface. The low orbit has made it a target for robotic spacecraft orbiting Mars.
By adjusting the apoapsis altitude of the elliptical Mars orbit, resonance with Phobos and Deimos is achieved, with a total of 16 Phobos and 9 Deimos flybys yielded by the trajectory designed for the PADME spacecraft, with details presented herein. Trajectory Designer, Mission Design Division, NASA ARC, Moffett Field, CA 94035, AIAA Member.
Where did the two natural satellites of Mars, Phobos and Deimos, come from? For a long time, their shape suggested that they were asteroids captured by Mars. However, the shape and course of their orbits contradict this hypothesis. Two independent and complementary studies provide an answer to this question.
I will present our best current understanding of the composition of Phobos and Deimos, focusing on visi-ble and near-infrared spectroscopy, and the implica-tions possible compositions have for the origin of the satellites. I will also discuss the prospects for future measurements.
