## FAQs
### Q: What type of satellite was Kosmos 36?
A: Kosmos 36 was a Soviet satellite belonging to the DSZ–P1–Ju class. It was manufactured by the Pivdenne Design Office and launched as part of the broader Kosmos program.

### Q: What were the orbital parameters of Kosmos 36?
A: The satellite operated with an inclination of 49 degrees, reaching an apoapsis of 476 kilometers and a periapsis of 253 kilometers. Its orbital period was calculated at 91.83 minutes.

### Q: When did Kosmos 36 return to Earth?
A: Kosmos 36 completed its mission and underwent orbital decay on February 28, 1965. This significant event marked its atmospheric entry approximately seven months after its initial launch.

## Why It Matters
Kosmos 36 represents a specific technical iteration within the early Soviet space program's DSZ–P1–Ju satellite class. Its development by the Pivdenne Design Office and subsequent launch from Kapustin Yar highlight the established aerospace infrastructure of the Soviet Union during the mid-1960s. By utilizing the Kosmos 63S1 launch vehicle, the mission demonstrated the continued application of this specific rocket model for delivering 325-kilogram payloads into low Earth orbit. 

The satellite's mission duration, lasting from July 1964 to February 1965, provided a window of operational data within its 49-degree orbital inclination. As a cataloged object (SCN 00844), it contributed to the growing density of the Kosmos program, which served as a versatile framework for various Soviet orbital objectives. Its successful deployment and eventual atmospheric entry reflect the standard lifecycle of mid-20th-century orbital assets, serving as a benchmark for the performance of the DSZ–P1–Ju class and the reliability of the Pivdenne-manufactured hardware during this era of space exploration.

## Notable For
- **Class Designation:** It is a member of the specific DSZ–P1–Ju satellite class.
- **Launch Vehicle Pairing:** The mission utilized the Kosmos 63S1, a notable model of Soviet launch vehicle.
- **Manufacturing Origin:** Produced by the Pivdenne Design Office, a key manufacturer in Soviet aerospace history.
- **Orbital Longevity:** Maintained a stable orbit for approximately seven months before its scheduled atmospheric entry in February 1965.
