## FAQs
### Q: What is the primary function of Luch 5B?
A: Luch 5B is a telecommunications satellite designed to provide relay and data transmission services. It specifically functions as part of the System for Differential Corrections and Monitoring (SDKM).

### Q: Who manufactured and operates Luch 5B?
A: The satellite was manufactured by JSC Information Satellite Systems Reshetnev and is operated by the Roscosmos State Corporation, the national space agency of Russia.

### Q: How was Luch 5B placed into orbit?
A: It was launched from Baikonur Cosmodrome Site 81/24 using a Proton-M heavy-lift rocket. A Briz-M space tug was utilized to assist the satellite in reaching its designated geostationary orbit.

## Why It Matters
Luch 5B is a significant asset in Russia's orbital telecommunications infrastructure. As a part of the System for Differential Corrections and Monitoring (SDKM), it plays a role in enhancing the precision and reliability of satellite-based data. Its deployment highlights the capabilities of the Ekspress-1000AM spacecraft bus and the continued use of the Proton-M heavy-lift vehicle for complex orbital missions. By maintaining a geostationary orbit, Luch 5B ensures consistent communication coverage, which is essential for both civil and specialized telecommunications requirements.

## Notable For
- **System Integration:** Serves as a dedicated component of the System for Differential Corrections and Monitoring (SDKM).
- **Heavy-Lift Heritage:** Launched using the Proton-M, a heavy-lift vehicle from the long-standing Soviet/Russian Proton rocket family.
- **Technical Platform:** Built on the Ekspress-1000AM spacecraft bus, a standard platform for modern Russian communication satellites.
- **Geostationary Positioning:** Operates as a fixed-point relay station in geostationary orbit to provide stable telecommunications.

## Body

### Mission and Purpose
Luch 5B (also known by the alias LUCH 5B) is an instance of a communications satellite. Its primary mission is to facilitate telecommunications as part of the broader Russian space infrastructure. It is specifically integrated into the System for Differential Corrections and Monitoring (SDKM), which provides specialized data corrections and monitoring services.

### Technical Profile
The spacecraft was constructed by JSC Information Satellite Systems Reshetnev, utilizing the Ekspress-1000AM spacecraft bus. It is identified in international satellite catalogs by the SCN number 38977 and the COSPAR ID 2012-061A. For computational and astronomical tracking, it is recognized by the Wolfram Language entity code "Satellite 38977".

### Launch Details
The launch of Luch 5B occurred on November 2, 2012. The mission originated from the Baikonur Cosmodrome, specifically Site 81/24. The launch sequence involved:
*   **Launch Vehicle:** The Proton-M, a heavy-lift vehicle known for carrying significant payloads into high orbits.
*   **Upper Stage:** A Briz-M space tug was employed to maneuver the satellite from its initial launch trajectory into its final orbital position.

### Orbital Operations
Luch 5B is a satellite of the geostationary orbit, meaning it orbits the Earth at the same rate the planet rotates, allowing it to remain over a fixed longitudinal point. This positioning is standard for telecommunications satellites requiring constant contact with ground stations. The satellite is managed and operated by the Roscosmos State Corporation.
