Martian Moons Block Sun In Unique Eclipse Images From Another Planet
Pasadena - Mar 17, 2004 This image shows the transit of Mars' moon Phobos across the Sun. The images were taken by the Mars Exploration Rover Opportunity on the morning of the 45th martian day, or sol, of its mission. This observation will help refine our knowledge of the orbit and position of Phobos. Other spacecraft ma be able to take better images of Phobos using this new information. This event is similar to solar eclipses seen on Earth in which our Moon passes in front of the Sun. The images were taken by the rover's panoramic camera.
The image was taken by the MER-A on sol 39 of its mission. Deimos passed slightly closer to the center of the Sun than expected, and arrived about 30 seconds early. This observation will help refine our knowledge of the orbit and position of Deimos.

Previously, on Sol 39 the rover Opportunity caught a transit, of the martian moon Deimos over the Sun. This event was more similar to solar transit of Mercury or Venus as seen from Earth but the apparent size of the transiting moon is still large enough to be readily seen without the aid of a telescope from the surface of Mars.
