## Why It Matters
GEOS-B (Explorer 36) is part of NASA's lineage of artificial satellites and represents the GEOS class within that lineage. Its launch demonstrates the use of the Thor-Delta expendable launch system from Vandenberg Space Launch Complex 2 during the late 1960s, and it occupies a defined place in the sequence of U.S. space missions—following Explorer 35 and preceding Solrad 9. As a cataloged spacecraft with COSPAR ID 1968-002A and SCN 03093, GEOS-B contributes to the historical record of spaceflight activities and program continuity for NASA and collaborators. The satellite's documented identifiers and launch details make it a verifiable data point for researchers, cataloguers, and anyone tracking the evolution of satellite classes and launch vehicle usage in that era.

## Notable For
