NASA’s Parker Solar Probe Uncovers The Origin Of Fast Solar Wind
NASA’s Parker Solar Probe, an unprecedented mission to “touch the Sun”, has made a significant breakthrough in solar research. The Probe has discovered the origin of the high-speed solar wind that continually gusts from the Sun, casting light on a longstanding mystery in heliophysics.
The fast solar wind is a stream of charged particles that continually flows out from the Sun, moving at speeds of around 500-800 kilometers per second. This wind shapes the nature of space weather and can impact technological systems on Earth and spacecraft in space. Until now, the precise source and mechanics of this fast wind remained elusive.
The Parker Solar Probe, launched in 2018, was designed to plunge closer to the Sun than any spacecraft before it. Its primary mission is to study the Sun’s outer corona and unravel the mysteries of solar wind and solar energetic particles. This recent discovery marks a monumental achievement in this mission’s goal.
The probe’s findings reveal that the fast solar wind originates from coronal holes – regions of the Sun’s corona that are less dense and cooler than surrounding areas. These holes allow high-speed streams of solar particles to escape into space, which then forms the fast solar wind.
“The Parker Solar Probe’s discovery significantly enhances our understanding of the Sun and its processes,” said Dr. Nicola Fox, director of the Heliophysics Division at NASA Headquarters in Washington. “It provides crucial insights into how solar winds influence our planet’s magnetosphere and overall space weather, which have direct implications for our space-based technology and exploration.”
The results of this landmark research are expected to have broad-ranging implications, from improving space weather prediction models to informing the design of future spacecraft. It will also aid in the preparation of manned missions to the Moon, Mars, and beyond by understanding the radiation environment astronauts will face on these journeys.
The detailed findings of the Parker Solar Probe’s discovery will be published in an upcoming issue of a leading scientific journal.

NASA’s Parker Solar Probe
NASA’s Parker Solar Probe, launched in August 2018, is humanity’s first mission to “touch” the Sun. It aims to uncover the secrets of the Sun’s atmosphere, and the corona, and to understand the origin and evolution of the high-speed solar wind that affects Earth’s magnetosphere and space weather. The Probe is named after astrophysicist Eugene Parker, the scientist who first proposed the concept of the solar wind in 1958.
