## Body

### Definition and Classification
Express AM-11 is defined as an **artificial satellite**, a human-made object placed into orbit around a celestial body, typically the Earth. It falls under the broader category of **spacecraft**, specifically engineered to operate in the space environment. While specific mission details are derived from its classification, the entity is primarily distinguished in structured data by its Wolfram Language entity code, **"28234"**.

### Characteristics of the Artificial Satellite Class
As an instance of an artificial satellite, Express AM-11 shares the defining characteristics of this class of objects.
- **Orbital Mechanics**: It is designed to maintain orbit through a balance of gravitational pull and forward velocity, which creates centrifugal force to counteract gravity.
- **Variants**: The class includes passive satellites (e.g., Project Echo), tethered satellites, and specialized units like orbital power plants.
- **Miniaturization**: The classification also encompasses miniaturized variants such as femtosatellites and picosatellites.

### Operational Context and Applications
Artificial satellites like Express AM-11 serve as the backbone for modern technological infrastructure. Their primary applications include:
- **Communication**: Enabling television, internet, and telephony signals.
- **Navigation**: Supporting GPS and positioning systems.
- **Military**: Providing secure communications and surveillance (e.g., Syracuse 4, Gonets-M).
- **Scientific Research**: Used for geodetic measurements (e.g., PAGEOS) and environmental monitoring.

### Historical Context
Express AM-11 operates within the historical framework of the Space Age, which began with the first artificial satellite, **Sputnik 1**, launched by the Soviet Union on October 4, 1957. This event marked the beginning of humanity's utilization of orbital space for various functional purposes.

### Technical Challenges
Objects in this classification face challenges regarding **space debris** and **orbital congestion**. Thousands of defunct satellites and fragments pose collision risks, leading to the development of space debris removal satellites to ensure the sustainability of orbital pathways used by entities like Express AM-11.
