Curiosity on Mars roaming, recently brought us new surprises, August 1, to stop it took a rare photograph, that is the two satellites of Mars, Phobos, Deimos, Mars Fair skies and over, a two-screen satellite lunar eclipse, Mars shines from this picture is the first time in human history, dry good, Curiosity!
Although the photo was taken on August 1, but this picture is regarded as a low priority, so dragged a week before returning to Earth.
Phobos English name is Phobos (Phobos), in Greek mythology, Ares, the son of the average radius of 11.1 km, orbit at a distance of 6,000 kilometers from the surface of Mars, Phobos, the larger and smaller Deimos , Deimos, the English name is derived Holmes (Deimos), the son of Ares, the same is Phobos's brother, two brothers are the fear of God, Deimos average radius of 6.2 kilometers, 23,460 kilometers away from Mars .
Phobos and Deimos are smaller than the moon, but because of Phobos from Mars close, so the point of view of Mars, Phobos is probably watching the moon in half the size of Earth.
This photo was taken in addition to meet us outside of science what help? Scientists say that two satellites overlap timing, you can use the gravity tidal phenomena arising from changes to Mars inside, you can also observe the interaction between the two satellites, the impact of each other's orbit, so Curiosity is not just sightseeing Oh nothing.
