NASA’s Parker Solar Probe is set to make a groundbreaking achievement as it reaches its closest approach to the Sun on Christmas Eve. The spacecraft, launched in August 2018, will come within a record-breaking 3.8 million miles (6.2 million kilometers) of the Sun’s surface at 6:53 am Eastern Time (11:53 GMT) on December 24. This historic event marks a major milestone in the seven-year mission aimed at improving our understanding of the Sun and space weather.
To put its proximity into perspective, if the distance between the Earth and the Sun were scaled to an American football field, Parker would be just four yards (3.65 meters) away from the end zone. This unprecedented close approach, known as perihelion, will temporarily disrupt direct communication with the probe, but mission teams will confirm its status through a beacon tone before the probe’s instruments begin collecting valuable data.

Parker’s heat shield will face extreme temperatures of up to 1,700°F (930°C) while its internal instruments are kept at a comfortable 85°F (29°C). Traveling at an incredible speed of 430,000 mph (690,000 km/h), Parker will explore the Sun’s outer atmosphere, or corona, offering insights into phenomena such as solar wind, coronal heating, and coronal mass ejections.
This flyby is the first of three record-breaking close encounters scheduled for March and June 2025, further advancing humanity’s knowledge of our star. The mission promises to unveil new data from uncharted territory and continues NASA’s legacy of bold scientific endeavors.
