NASA's Parker Solar Probe Survives Historic Christmas Eve Flyby, Closest Ever to Sun
Parker dances with our star
Science breaks new ground
NASA's Parker Solar Probe has achieved a historic milestone, surviving its closest-ever approach to the Sun on Christmas Eve 2024, flying just 3.8 million miles above the star's surface at a record-breaking speed of 430,000 miles per hour.
After seven days of silence, mission control received a beacon tone late on December 26, confirming the spacecraft was safe and operating normally following its daring journey through the Sun's corona. The probe endured temperatures up to 1,800 degrees Fahrenheit, protected by its innovative carbon foam shield designed to withstand up to 2,600 degrees.
'Flying this close to the Sun is a historic moment in humanity's first mission to a star,' said Nicky Fox, head of NASA's Science Mission Directorate in Washington. 'By studying the Sun up close, we can better understand its impacts throughout our solar system, including on the technology we use daily on Earth and in space.'
The groundbreaking mission, launched in 2018, has utilized seven Venus flybys over six years to gradually position itself closer to the Sun. The probe reached its optimal orbit following its final Venus flyby on November 6, 2024, enabling it to study the Sun's processes every three months while maintaining a safe distance from excessive heat and radiation.
'Parker Solar Probe is braving one of the most extreme environments in space and exceeding all expectations,' said Nour Rawafi, project scientist at the Johns Hopkins Applied Physics Laboratory, which designed and operates the spacecraft. 'This mission is ushering in a new golden era of space exploration.'
The probe's measurements are helping scientists understand why the Sun's corona reaches such extreme temperatures, trace the origin of solar wind, and study how energetic particles are accelerated to nearly half the speed of light. These insights are crucial for predicting space weather events that can impact Earth's technology and communication systems.
The spacecraft will continue its mission with upcoming solar passes scheduled for March 22 and June 19, 2025, promising to unlock more secrets about our nearest star and its influence throughout the solar system.
