Phobos and Deimos Solar Transits

by Jim Bell (Cornell University), Mark Lemmon (Texas A&M University), Mike Wolff (Space Science Institute), and the Cornell Pancam Uplink Team (Heather Arneson, Emily Dean, Miles Johnson, Elaina McCartney, Jon Proton, Dmitry Savransky)


Because the rovers are located near the Martian equator, it is possible to occasionally see Phobos and Deimos pass in front of the sun. These images are also helpful in refining the orbits of the Martian moons.
