## Body
### Launch Details
Shijian-2B was launched on September 19, 1981, at 00:00 UTC from Launch Complex 2 at the Jiuquan Satellite Launch Center in the Gobi Desert of Inner Mongolia. The launch window and exact time are documented in space tracking records.

### Technical Specifications
The spacecraft was launched aboard a Feng Bao 1 (Chinese: 风暴一号, meaning "Storm" or "Tempest") carrier rocket, which was China's first liquid-fueled carrier rocket developed for satellite launches. The Feng Bao 1 was a three-stage rocket standing approximately 32 meters tall with a diameter of 2.3 meters.

### Mission Classification
As a Shijian-series satellite, Shijian-2B was part of China's space technology development program. The Shijian series (meaning "practice" in Chinese) was designed for various space technology experiments and applications. The "2B" designation indicates it was the second satellite in this particular series.

### Orbital Information
While specific orbital parameters are not provided in the source material, as a spacecraft launched in 1981, Shijian-2B would have been placed in low Earth orbit, typical for satellites of that era and mission type.

### Documentation and Tracking
The spacecraft is documented in international space tracking databases with the COSPAR designation 1981-093A and satellite catalog number 12842. It is recognized in the Wolfram Language as Entity["Satellite", "12842"], indicating its inclusion in computational knowledge systems for satellite tracking and analysis.
