## Why It Matters
Magion 4 played a crucial role in advancing our understanding of Earth's magnetosphere and its interactions with solar wind. As part of the Interball program, it contributed to a broader scientific effort to study plasma processes, which are essential for comprehending space weather and its effects on Earth. The satellite's data helped scientists analyze the behavior of charged particles in the magnetosphere, improving models of geomagnetic storms and their potential impacts on communication and navigation systems. Additionally, Magion 4 represents the Czech Republic's continued involvement in space science, building on the legacy of the Czechoslovak Magion program.

## Notable For
- Being the fourth satellite in the Magion series, following Magion 3 and preceding Magion 5.
- Its role as a subsatellite in the Interball program, which focused on studying Earth's magnetosphere.
- Launching from the Plesetsk Cosmodrome, a major Russian spaceport, using a Molniya-M rocket.
- Contributing to the understanding of plasma processes in the magnetosphere, which are critical for space weather research.
- Representing the Czech Republic's scientific and technological capabilities in space exploration.

## Body
### Overview
Magion 4 is a small scientific satellite developed by the Czech Republic. It is part of the Magion series, which began under Czechoslovakia and continued after the country's dissolution. The satellite was designed to study plasma processes in Earth's magnetosphere, particularly focusing on the interactions between solar wind and the Earth's magnetic field.

### Launch and Deployment
- **Launch Date**: August 2, 1995
- **Launch Vehicle**: Molniya-M rocket
- **Launch Site**: Plesetsk Cosmodrome Site 43, Russia
- **COSPAR ID**: 1995-039F

Magion 4 was deployed as part of the Interball program, a collaborative effort to study the Earth's magnetosphere using pairs of satellites. The program aimed to gather data on plasma processes, which are essential for understanding space weather and its effects on Earth.

### Technical Specifications
- **Mass**: 58.7 kilograms
- **Classification**: Artificial satellite
- **Country of Origin**: Czech Republic

### Role in the Interball Program
The Interball program consisted of two pairs of spacecraft: one pair above the polar aurora and another in the magnetospheric tail. Magion 4 served as a subsatellite, working in conjunction with other satellites to collect data on plasma processes. This data was crucial for improving models of geomagnetic storms and their potential impacts on communication and navigation systems.

### Legacy and Successors
Magion 4 was preceded by Magion 3, a Czechoslovak satellite, and followed by Magion 5, another Czech satellite. The Magion series has been instrumental in advancing the Czech Republic's capabilities in space science and technology.
