NASA’s Parker Solar Probe astonished scientists by making an unprecedented close flyby of the sun on December 24, 2023. This remarkable spacecraft, roughly the size of a small car, ventured within 3.86 million miles of the sun’s surface, a record distance for any human-made object. Traveling at an incredible speed of about 430,000 mph, it embarked on its daring journey early that morning.
The goal of this mission is to investigate the sun’s outer atmosphere, or corona, and unravel the mysteries behind solar storms. The probe’s observations during this close encounter could reveal why the corona is significantly hotter than the sun’s surface itself. As it skims closely to the sun, the probe may pass through intense solar plasma streams and observe the dynamic regions of the star.
NASA anticipates receiving the first images from this extraordinary close approach in January 2024, after a brief communication blackout during the maneuver. These valuable insights will aid scientists in predicting space weather events that could impact Earth, such as solar flares and charged particle emissions, which can damage satellites and disrupt power grids.
Launched in 2018, the Parker Solar Probe has completed over 20 orbits around the sun, and this encounter marks the start of its final close observations, set during the sun’s active solar maximum phase. Named after astrophysicist Eugene Parker, who first proposed the existence of solar wind, this mission represents a significant leap forward in our understanding of solar phenomena that influence our planet.
