Solar eclipses on Mars around Mars, the shadow of Phobos was seen in pictures transmitted to Earth. One of these photos was from the NASA rover "Opportunity". Solar eclipses on Mars The two moons of Mars, Phobos and Deimos, are much smaller than the Moon, greatly reducing the frequency of solar eclipses on that planet. Neither moon's apparent diameter is large enough to cover the disk of the sun, and therefore they are annular solar eclipses and can also be considered transits. Due to the small size of Phobos (about ) and its rapid orbital motion, an observer on the surface of Mars would
Solar System Exploration Research Virtual Institute on one or more aspects of lunar science investigations of the Moon (including lunar samples), from the Moon, and on the Moon. In 2013 the NLSI became the Solar System Exploration Research Virtual Institute and expanded its scope to include Near-Earth asteroids and Phobos and Deimos. The Solar System Exploration Research Virtual Institute (SSERVI) is composed of thirteen U.S. teams, and ten international partners. The teams are listed below: US TEAMS: Focus: Formation of terrestrial planets and asteroid belt, modeling of the Moon's origin and Phobos/Deimos, history of NEAs and lunar bombardment, NEA origins, identification and characterization boulder.swri.edu Focus: Studies
