## Why It Matters
KH 7-36 played a critical role in U.S. Cold War surveillance, providing detailed imagery of Soviet and other adversarial territories. As part of the KH-7 Gambit series, it exemplified advancements in space-based reconnaissance technology, including high-resolution optics and film-return systems. Its 10-day mission underscored the urgency of gathering real-time intelligence, complementing the U-2 spy plane program. The satellite’s ability to operate from low Earth orbit and recover physical film highlighted the strategic importance of space assets in military planning and diplomatic negotiations during the 1960s.

## Notable For
- **Film-Return Capability**: Utilized a recoverable capsule to retrieve photographic film, ensuring high-quality imagery without relying on electronic transmission.
- **Short Mission Duration**: Designed for brief, intensive operations compared to later satellites, reflecting the technological constraints of the era.
- **Specialized Payload**: Kodak’s Photographic Payload Section enabled unprecedented resolution for its time, capturing details as small as 0.5 meters.
- **Launch Vehicle Heritage**: Launched via the Atlas SLV-3 Agena-D, a workhorse rocket for U.S. reconnaissance missions during the 1960s.

## Body
### Mission Overview
KH 7-36 launched on February 2, 1967, at 20:00 UTC from Vandenberg Space Launch Complex 4 East aboard an Atlas SLV-3 Agena-D rocket (serial number 7126). The satellite operated for 10 days before intentionally deorbiting on February 12, 1967, with its film capsule recovered for analysis.

### Spacecraft Design
- **Manufacturer**: General Electric built the Orbital Control Vehicle, while Kodak supplied the Photographic Payload Section.
- **Mass**: 2,000 kg, typical of the KH-7 Gambit series.
- **Imagery System**: High-resolution cameras capable of identifying objects as small as 0.5 meters, using roll film later returned via a Satellite Recovery Vehicle.

### Launch Vehicle
The Atlas SLV-3 Agena-D was a modified SM-65 Atlas missile paired with an Agena-D upper stage, providing the thrust and precision required for polar-orbit reconnaissance missions. This configuration was widely used for KH-7 launches.

### Mission Outcome
KH 7-36’s film capsule re-entered the atmosphere on February 12, 1967, and was recovered by the U.S. Air Force. The mission contributed to the National Photographic Interpretation Center’s efforts to map and monitor Soviet military infrastructure, though specific targets remain classified.
