Parker Solar Probe

Definition

The Parker Solar Probe is a NASA spacecraft designed to study the outer corona of the Sun, providing crucial data about solar magnetic fields and solar wind. Launched in 2018, it aims to improve our understanding of solar activity cycles and their effects on the interplanetary magnetic field and heliosphere. By getting closer to the Sun than any previous spacecraft, it plays a vital role in shaping future solar exploration and advancing space mission technology.

5 Must Know Facts For Your Next Test

1. The Parker Solar Probe is designed to get as close as 4 million miles to the Sun's surface, much closer than any previous spacecraft.
2. It carries a suite of instruments to measure electric and magnetic fields, plasma waves, and energetic particles in the Sun's atmosphere.
3. One of its key goals is to help scientists understand how solar wind accelerates and why the corona is much hotter than the Sun's surface.
4. The mission will last approximately seven years, with multiple close passes around the Sun, allowing for extensive data collection over time.
5. Findings from the Parker Solar Probe are expected to enhance our ability to predict space weather events that can affect satellites and power grids on Earth.
