NASA’s Parker Solar Probe has traveled to inside simply 3.86 million miles (6.1 million kilometers) of the solar’s floor — a brand new document — on Christmas Eve. You can observe Parker’s landmark second on NASA’s Eyes On The Solar System web page.
In certainly one of humankind’s most spectacular feats of house exploration, Tuesday, Dec. 24 noticed a closely armored NASA spacecraft — no greater than a small automotive — turned the closest human-made object to the solar in historical past. It additionally noticed humanity’s closest-ever strategy to a star and the fastest-ever human-made object break its velocity document.
Monumental Feat
This monumental feat of exploration occurred at 11:53 UTC (6:53 a.m. EST) on Tuesday, Dec. 24, as Parker performed an unprecedented shut flyby of the solar, reaching simply 3.86 million miles (6.1 million kilometers) from its floor. It was its twenty second shut strategy to the solar.
At 96% of the gap between the solar and Earth — properly inside the orbit of Mercury at about 39% — it’s the closest any human-made object has ever been to the solar.
Dr. Nour Raouafi, the venture’s scientist on the Johns Hopkins Applied Physics Laboratory, equates this mission’s significance to the moon touchdown in 1969. “It’s the second we now have been ready for for almost 60 years,” he mentioned throughout a media roundtable on the American Geophysical Union’s annual assembly on Dec. 10, 2024. “In 1969, we landed people on the moon. On Christmas Eve, we embrace a star — our star.”

‘Hyper-Close’
In what NASA calls a “hyper-close regime,” Parker will lower by means of plumes of plasma nonetheless linked to the solar and be shut sufficient to go inside a photo voltaic eruption, “like a surfer diving below a crashing ocean wave,” based on NASA.
The warmth that Parker will likely be subjected to when as its closest to the solar was “almost 500 occasions the most well liked summer season day we are able to witness on Earth,” mentioned Raouafi.
Parker was already the quickest object ever constructed on Earth, however because it reached its closest level to the solar, Parker will go one additional by touring at 430,000 mph (690,000 kph), breaking its information for velocity and distance. According to the mission’s web site, that’s quick sufficient to get from Philadelphia to Washington, D.C., in a single second.
Mission operators on the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland will lose contact with the probe for 3 days and anticipate a beacon tone on Dec. 27, 2024, that may verify its survival.
Parker will full two extra hyper-close passes on the similar distance on March 22 and June 19, 2025.
Wishing you clear skies and extensive eyes.
