**COLLEGE PARK, MD** – NASA’s Parker Solar Probe, launched in 2018, is venturing closer to the sun than any human-made object before, providing unprecedented insight into the star’s mysteries. At the forefront of this groundbreaking mission are physicists from the University of Maryland, who are making significant contributions to understanding the sun’s behavior.
The Parker Solar Probe, nicknamed “the mission to touch the sun,” endures extreme heat and radiation while traversing the corona, the sun’s outermost layer. Its mission aims to answer long-standing questions about the solar wind and the corona’s unexpected high temperature.
Dr. James Drake, a Distinguished University Professor at UMD, and Dr. Marc Swisdak, a research scientist at UMD’s Institute for Research in Electronics & Applied Physics, are key members of the Parker Solar Probe team. Their expertise in magnetic reconnection, a process where opposing magnetic fields interact, has proven crucial to the mission’s discoveries.
Early data revealed that magnetic reconnection is more common than previously thought, particularly in the heliospheric current sheet, a boundary within the sun’s magnetic bubble. This finding led to further discoveries, including the existence of “switchbacks” – sudden changes in the solar wind’s magnetic field.
UMD researchers, including Dr. Drake and Dr. Swisdak, proposed that these switchbacks are created by magnetic reconnection in the corona. Their simulations support this theory, highlighting the crucial role of magnetic reconnection in driving the solar wind and shaping its behavior.
The Parker Solar Probe continues to collect data, providing valuable information about the sun’s activity and its potential impact on Earth. Understanding the solar wind is essential for predicting space weather, which can disrupt power grids and endanger astronauts.
The UMD team’s research also holds broader implications, providing insights into the behavior of winds throughout the universe. This knowledge contributes to understanding the habitability of planets, as solar wind helps protect them from harmful radiation.
As the Parker Solar Probe prepares for its deepest dive into the sun’s corona in December 2024, the UMD team eagerly anticipates new discoveries that will advance our understanding of the sun and its influence on our planet and the cosmos.
