## Why It Matters
4MV represents a distinct Soviet-era spacecraft design used for exploring neighboring planets, specifically Mars and Venus. As a spacecraft model classified under planetary probes, it served as the baseline architecture for multiple Soviet uncrewed missions. Its association with missions such as Venera 9 links the design to established planetary exploration efforts in the 1970s. Documentation and categorization across Wikimedia projects (Wikipedia in several languages and a Commons category) and an entry in the Google Knowledge Graph indicate that 4MV is a recognized and referenced design in spaceflight history. Understanding 4MV helps contextualize Soviet spacecraft engineering approaches to interplanetary missions and provides a reference point for researchers comparing probe classes and mission families in Cold War-era planetary exploration.

## Notable For
- Being a Soviet spacecraft design specifically used for probes to both Mars and Venus.  
- Direct association with Venera 9, the 1975 Soviet uncrewed mission to Venus.  
- Classification as a spacecraft model and as a subclass of planetary probe.  
- Presence across multiple Wikimedia language pages and a dedicated Commons category.  
- Having a Google Knowledge Graph identifier (/g/11cmszmz_g).
