NASA's Parker Solar Probe has successfully attempted its closest approach to the sun, reaching within 3.8 million miles of its corona. NASA expects to confirm the probe's condition by Friday. Through this mission, the probe aims to gather crucial data on solar winds, coronal mass ejections, and the sun's impact on Earth. This close pass will aid in understanding longstanding solar mysteries and the behavior of the sun, contributing to space weather forecasting over the next seven years.
