 | | Phobos and the smaller, more distant satellite, Deimos, were discovered in 1877 by Asaph Hall, an astronomer at the United States Naval Observatory in Washington, D.C. Hall had been hunting for martian satellites for some time, and was about to abandon the search when he was encouraged by his wife to continue. |
 | | Phobos was the target of the ill-fated Phobos 1 and Phobos 2 spacecraft, launched by the Soviet Union in 1988. |
 | | Phobos 2 actually reached Mars in 1989 and obtained a few pictures of the satellite---it also captured the shadow of Phobos cast upon the martian surface using its thermal infrared imager, Termoskan. |
