Parker Solar Probe, NASA’s historical mission to solve the sun’s mysteries, lives and well after skimming the sun in just 15 million miles from its surface. This is far closer than anything spacecraft has ever gone – the previous record was determined by Helios B 1976 and broken by Parker on October 29th – and this maneuver has exposed the spacecraft for intense heat and solar radiation in a complex solar wind environment, NASA said in a statement on Thursday.
On November 5th, the spacecraft made the closest approach, called perihelion. Parker Solar Probe achieved a top speed of 21
3,200 miles per hour and introduced a new record for spacecraft speed. At this distance, the intense sunlight heated the sunny side of the Probe heat shield, called the Thermal Protection System, to about 820 degrees Fahrenheit. This temperature will climb to 2500 Fahrenheit, as spacecraft is approaching the sun, NASA said.
“Parker Solar Probe was designed to take care of itself and its valuable payload under this approach, without control from us Earth – and now we know it succeeded,” said Thomas Zurbuchen, Associated Administrator at NASA’s Directorate for science mission in washington On November 7, the mission controllers at the Johns Hopkins University Applied Physics Lab received the status protection from spacecraft at. 16:46.

The background indicates status “A” – the best of all four possible status signals, which means that Parker Solar Probe works well with any instrument that drives and collects scientific data and, if there were any minor problems, they were resolved autonomously by the spacecraft. “Parker is the culmination of six decades of scientific progress. Now we have realized humanity’s first close visit to our star, which will have consequences not only here on earth, but for a deeper understanding of our universe,” added Zurbuchen.

Parker Solar Probes first solar phase began on October 31st, and the spacecraft continues to collect scientific data by the end of the solar phase on November 11th. It will be several weeks after the end of the sunrise phase before the science data begins to link down to the ground. The spacecraft repeatedly breaks its own speed record, as its orbital approaches the star and spacecraft travels faster and faster at perihelion, NASA said.
