Phobos And Deimos & Mars Environment experiment. PADME could launch on a Medium-lift class launch vehicle. The spacecraft would fit within all Atlas V, Delta IV, and Falcon 9 launch vehicle fairings. If selected, PADME would have been launched in August 2020 and reached Mars seven months later, by March 2021. PADME includes the participation of scientists from Belgium, France, Italy, and Japan. Phobos And Deimos & Mars Environment Phobos And Deimos & Mars Environment (PADME) is a low-cost NASA Mars orbiter mission concept that would address longstanding unknowns about Mars' two moons Phobos and Deimos and their environment. The PADME mission competed for Discovery Program
Transit of Phobos from Mars 57.75 seconds to get a time of 20:49:02.4 UTC for the center of the shadow. Putting in the longitude/latitude/altitude coordinate values -124,14,0 into JPL Horizons gives an expected time of 20:49 for the transit, which is in good agreement once again. On 1 September 1999 the distance between the Earth and Mars was 9.9 light-minutes. Transit of Phobos from Mars A transit of Phobos across the Sun as seen from Mars takes place when Phobos passes directly between the Sun and a point on the surface of Mars, obscuring a large part of the Sun's disc for an observer on
