Шаблон:Infobox spacecraft classШаблон:Short description The 4MV planetary probe (short for 4th-generation Mars-Venus probe) is a designation for a common design used for Soviet unmanned probes to Mars and Venus.

It was an incremental improvement of earlier 3MV probes and was used for Mars missions 2 to 7 and Venera missions 9 to 16. Different versions of the bus exist, for example 4V-1, 4V-M and 4V-2.[1][2] The same base design was also used for earth-orbiting space observatories.[3]

Design

The spacecraft bus has a height of Шаблон:Convert and a solar panel span of Шаблон:Convert. The central section of the bus has a diameter of about Шаблон:Convert and contained propellant. The main engine (KTDU-425) is encircled by a conical instrument compartment with the diameter of Шаблон:Convert at the base.[4] While Mars 2,3 and Kosmos 419 used the KTDU-425, 4MV buses after 1971 used the KTDU-425A).[5]
