description Overview

Phobos 2

Phobos 2 was a Soviet spacecraft launched in 1988 as part of a mission to study Mars and its moon Phobos. It entered orbit around Mars in 1989 and returned observations of the planet before contact with the spacecraft was lost shortly before its planned encounter with Phobos. The mission was intended to combine Mars-orbiting measurements with close study of the Martian moon.

Mars 3

Mars 3 was a Soviet robotic mission consisting of an orbiter and a lander, launched on 28 May 1971. Its lander reached the Martian surface in December 1971 and became the first spacecraft to make a soft landing on Mars. It transmitted data for about 20 seconds before contact was lost, while the orbiter continued observations from Mars orbit.
