Mission Overview
The primary scientific objectives of the Parker Solar Probe are to trace the flow of energy that heats the Sun’s corona, determine the structure and dynamics of the solar wind, and explore the mechanisms that accelerate energetic particles. To achieve these goals, the probe utilizes a series of gravity assists from Venus, progressively reducing its orbital perihelion—the point of closest approach to the Sun.
This intricate trajectory, requiring precise orbital maneuvers, allows the spacecraft to repeatedly sample the Sun’s atmosphere at increasingly closer distances. The mission overcame significant technological hurdles, particularly in designing and building a heat shield capable of withstanding temperatures exceeding 1,370°C (2,500°F).
Instrumentation and Data Collection
The Parker Solar Probe carries a suite of cutting-edge instruments designed to measure various aspects of the Sun’s environment. These instruments collect data on magnetic fields, plasma properties, energetic particles, and solar wind structures. The data is processed onboard before being transmitted back to Earth, where scientists analyze it to reveal the secrets of the Sun.
| Instrument | Function | Data Types Collected |
|---|---|---|
| FIELDS | Measures electric and magnetic fields | Electric field strength, magnetic field strength, wave properties |
| SWEAP | Measures the properties of the solar wind | Electron density, proton density, temperature, velocity |
