Mars Orbiter 96 Spacecraft Information
The Mars 94 spacecraft is built around the PHOBOS-type spacecraft structure (modified with due account of the experience gained in the PHOBOS mission).
The spacecraft will consist of an orbiter with two rotating platforms for pointing optical instruments, two small autonomous stations, two penetrators, and autonomous engine unit.
Orientation
constant sun/star (three-axis), accuracy 1deg.;
sun orientation is possible (with the spacecraft spinning around the axis directed to the
Sun)
