The groundbreaking Parker Solar Probe from NASA made a remarkable achievement on Tuesday, approaching the sun closer than any other spacecraft in existence, with its thermal shield subjected to extreme temperatures that exceed 930 degrees Celsius (1,700 degrees Fahrenheit).

Since its launch in August 2018, the spacecraft has been on a seven-year mission aimed at enhancing our scientific comprehension of the sun and aiding in predicting space-weather phenomena that could influence life on Earth.

This landmark flyby was scheduled to take place at exactly 11:53 Greenwich Mean Time, although mission experts will need to wait until Friday for validation due to a temporary loss of contact with the spacecraft while it nears the sun.

“At this moment, the Parker Solar Probe is flying nearer to a star than any object has previously accomplished,” stated NASA representative Nicky Fox in a social media video on Tuesday morning, being 6.1 million kilometers (3.8 million miles) away.

“It’s just a complete ‘yay, we achieved it’ moment.”

If the gap between Earth and the sun parallels the distance of an American football field, measuring 109.7 meters, the spacecraft should have been approximately four meters from the goal line at the instant of closest approach — referred to as perihelion.

“This exemplifies one of NASA’s ambitious missions, undertaking achievements that no one has ever accomplished to resolve longstanding inquiries regarding our universe,” said Parker Solar Probe program scientist Arik Posner in a statement on Monday.

“We’re eager to receive the first status report from the spacecraft and begin gathering scientific data in the weeks ahead.”

Thanks to the efficiency of the heat shield, the probe’s internal equipment remains near ambient temperature — about 29 C (85 F) — while it examines the sun’s outer atmosphere, the corona.

Parker will also travel at an astonishing speed of approximately 690,000 kilometers per hour (430,000 miles per hour), swift enough to cover the distance from Washington, D.C. to Tokyo, Japan in less than a minute.

“Parker will genuinely return data from uncharted regions,” remarked Nick Pinkine, mission operations manager at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.

“We are excited to receive communications from the spacecraft as it circles back around the sun.”

By venturing into such extreme environments, Parker has been aiding scientists in unraveling some of the sun’s most significant enigmas: the origin of solar wind, the reason the corona is warmer than the surface beneath, and how coronal mass ejections — enormous plasma clouds that traverse space — are generated.

The flyby on Christmas Eve marks the first of three record-breaking close encounters, with the next two — on March 22 and June 19, 2025 — both anticipated to bring the probe back to a similarly close proximity to the sun.
