   Explanation: Mars has two tiny moons, Phobos and Deimos, named for the
   figures in Greek mythology Fear and Panic. Detailed surface views of
   smaller moon Deimos are shown in both these panels. The images were
   taken in 2009, by the HiRISE camera on board the Mars Reconnaissance
   Orbiter spacecraft, NASA's long-lived interplanetary internet
   satellite. The outermost of the two Martian moons, Deimos is one of the
   smallest known moons in the Solar System, measuring only about 15
   kilometers across. Both Martian moons were discovered in 1877 by Asaph
   Hall, an American astronomer working at the US Naval Observatory in
   Washington D.C. But their existence was postulated around 1610 by
   Johannes Kepler, the astronomer who derived the laws of planetary
   motion. In this case, Kepler's prediction was not based on scientific
   principles, but his writings and ideas were so influential that the two
   Martian moons are discussed in works of fiction such as Jonathan
   Swift's Gulliver's Travels, written in 1726, over 150 years before
   their discovery.
