## FAQs
### Q: What is Dodecahedron?
A: Dodecahedron is a technology demonstration spacecraft — a spacecraft class used to demonstrate experimental technologies — launched on 1965-03-09. It is cataloged under COSPAR ID 1965-016H and SCN 01272.

### Q: When and where was Dodecahedron launched?
A: Dodecahedron was launched on 1965-03-09 from Vandenberg Space Launch Complex 2. The recorded significant event is a rocket launch at that site on that date.

### Q: Which rocket launched Dodecahedron?
A: Dodecahedron was launched on a Thor-Agena D launch vehicle. This launch is recorded with the same 1965-03-09 launch date and Vandenberg SLC-2 start point.

## Why It Matters
Dodecahedron represents a class of spacecraft specifically used to demonstrate and test new or experimental space technologies. As a technology demonstration spacecraft, its primary role is to provide flight heritage and operational data for technologies that may later be used on operational missions. The concrete identifiers and launch details — COSPAR 1965-016H, SCN 01272, launch on 1965-03-09 from Vandenberg SLC-2 aboard a Thor-Agena D — place Dodecahedron within the historical context of mid-1960s spaceflight activity. That context is useful for researchers tracing the development and testing of space technologies, cataloguers maintaining satellite registries, and historians documenting launch vehicle use and launch-site operations. The available media and identifiers (image link, Google Knowledge Graph ID, and a Polish-language Wikipedia link) support cross-referencing and verification across archival and knowledge resources.

## Notable For
- Being classified explicitly as a technology demonstration spacecraft (used to demonstrate experimental technologies).  
- Having a precise launch record: 1965-03-09 launch from Vandenberg Space Launch Complex 2.
