2MV

The 2MV planetary probe (short for 2nd generation Mars-Venus) is a designation for a common design used by early Soviet unmanned probes to Mars and Venus. It was an incremental improvement of earlier 1MV probes and was used for the Venera 5 and Venera 6 missions to Venus. It was standard practice of the Soviet space program to use standardized components as much as possible. All probes shared the same general characteristics and differed only in equipment necessary for specific missions.[1] Each probe also incorporated improvements based on experience with earlier missions. It was superseded by the 3MV family.

2MV-4 type spacecraft

Design

The probe consisted of three primary parts.

Orbital Compartment

The core of the stack was a pressurized compartment called the Orbital Compartment measuring 2.1 meters with a diameter of 1.1 meters. Also mounted on the Orbital Compartment was a parabolic high-gain antenna, used for long-range communications.

Payloads

Depending on the mission, the probe would carry specific instruments or a detachable landing module.[2]

Engine

Course correction capabilities were provided by a KDU 414 engine attached to the top of the Orbital Compartment.

Variants[3]
gollark: I mostly use it to follow somewhat interesting stuff like a thread on exotic political compasses.
gollark: Also his actual tweets, quite often.
gollark: The mostly irrelevant village I live in has had 4G connectivity for a year or so, which is nice. I wish they'd roll that out more rather than overhyping pointless 5G.
gollark: The law is with you as long as few enough people start saying wrong things™ on the internet (or, well, specifically your platform) that people start complaining a lot. Public opinion might not be. The issue with making a new less-moderated version of something is that it inevitably attracts a few people who genuinely care about free speech a lot, and probably a lot who want to say terrible/stupid things somewhere.
gollark: My website is very size-optimized and does a lot of caching.
