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
Mars Terahertz Microsatellite Wave Instrument) on board the Jupiter Icy Moons Explorer, which the institute jointly developed with ESA and DLR (German Aerospace Center). Unlike the Japanese Space Agency (JAXA), which is under the jurisdiction of the Ministry of Education, Culture, Sports, Science and Technology, NICT's parent agency is the Ministry of Internal Affairs and Communications (MIC). MIC formally approved the Mars Terahertz Microsatellite in early 2017. The preliminary lander's dimensions are a 50 cm cube, and may have a mass of including propellant. Its landing system is proposed to employ an inflatable aeroshell decelerator, and an airbag. Mars Terahertz Microsatellite The Mars
