1988 Soviet missions to Mars
Phobos probe model The Phobos program (Russian: Фобос, Fobos) was an uncrewed space mission consisting of two probes launched by the Soviet Union to study Mars and its moon Phobos. Phobos 1 was launched on 7 July 1988, and Phobos 2 on 12 July 1988.
Phobos 1 suffered a terminal failure en route to Mars. Phobos 2 attained Mars orbit and made several passes collecting data on the Martian system, but contact was lost before the final phase, prior to deployment of the planned Phobos landers.
