## Why It Matters
Cosmos 929 serves as a specific historical data point in the timeline of Soviet space exploration, specifically regarding the development of the TKS (Transportnyi Korabl’ Snabzheniya) spacecraft system. The TKS program was conceived in the late 1960s to create a heavy resupply and transport vehicle for space stations. As an instance of this class, Cosmos 929 represents the testing and operational history of this technology.

The mission utilized the Proton-K, a heavy-lift launch vehicle that was a workhorse for the Soviet/Russian space program, highlighting the mass and orbital requirements of the TKS spacecraft. Launching from Baikonur Cosmodrome Site 81/24, the mission contributed to the legacy of the "Cosmos" designation, which was historically used to obscure the specific nature of Soviet military and experimental spacecraft. By recording specific orbital parameters and hardware configurations, Cosmos 929 helps space historians track the evolution of automated docking and logistics systems that preceded modern resupply vessels.

## Notable For
- **Classification:** Specifically identified as an "instance of" the TKS spacecraft class.
- **Launch Vehicle:** Utilized the Proton-K, a prominent Russian/Soviet carrier rocket.
- **Launch Infrastructure:** Launched from Baikonur Cosmodrome Site 81/24.
- **Historical Context:** Part of a spacecraft lineage conceived in the late 1960s.
- **Identification:** Uniquely tracked via COSPAR ID 1977-066A and Satellite Catalog Number 10146.

## Body

### Mission Identity and Classification
Cosmos 929 is officially classified as an instance of the **TKS spacecraft**. The TKS (Transport Supply Spacecraft) was a system conceived by the Soviet Union in the late 1960s. The "Cosmos" designation was a standard practice for Soviet missions, often used for military or experimental flights to limit public exposure to specific mission objectives.

### Launch Operations
The mission commenced with a rocket launch event on **July 17, 1977**.
- **Time:** The precise launch time was 09:00:00.
- **Location:** The launch originated from **Baikonur Cosmodrome Site 81/24**, a specific pad at the historic cosmodrome.
- **Vehicle:** The launch vehicle employed was the **Proton-K**, a heavy-lift rocket used frequently for large Soviet payloads.

### Technical Identifiers
The spacecraft is tracked and referenced through several international and national databases:
- **COSPAR ID:** 1977-066A (The "A" denotes the primary payload or object resulting from the 66th launch of 1977).
- **Satellite Catalog Number (SCN):** 10146.
- **Wolfram Language Entity Code:** Entity["Satellite", "10146"].

### Related Entities
The spacecraft is functionally related to two major components of the Soviet space infrastructure:
1.  **TKS:** The spacecraft class/design.
2.  **Proton-K:** The delivery system (carrier rocket).
