Parker Solar Probe reaches a top speed of 213,200 miles at the time

(NASA) – The Parker solar probe is alive and well after flying over the sun just 15 million kilometers from the surface of our star.
It is much closer to all spacecraft – the previous record was set by Helios B in 1976 and defeated by Parker on October 29 – and this maneuver exposed him to intense heat and solar radiation in a complex environment solar winds.
"Parker Solar Probe was designed to take care of itself and its valuable payload during this close-up approach, without any control on our part on Earth – and we now know that it succeeded," said Thomas Zurbuchen, Director NASA Science Mission Directorate associate at the agency. headquarters in Washington.
"Parker is the culmination of six decades of scientific progress. Now we have made the first visit of our star to humanity, which will have implications not only here on Earth, but also for a deeper understanding of our universe. "

Mission controllers at the Johns Hopkins University Applied Physics Laboratory received the probe status tag at 4:46 PM. EST November 7, 2018.
The beacon indicates status "A" – the best of four possible status signals, which means that Parker Solar Probe works well with all instruments operating and collecting scientific data. In case of minor problems, they have been solved autonomously by the spacecraft.
On November 5, at the closest approach to perihelion, the Parker solar probe reached a top speed of 213,200 mph, setting a new speed record for spacecraft. In addition to new records for the closest approach to the Sun, Parker Solar Probe will repeatedly beat its own speed record as its orbit approaches the star and the spacecraft gets would move faster and faster to perihelion.
At this distance, the intense sunlight heated the Solar Parker solar thermal shield, called the sun-facing thermal protection system, to about 820 degrees Fahrenheit.
This temperature will rise to 2500 F as the spacecraft approaches closer to the Sun – but all the while, the instruments and systems of the spacecraft protected by the heat shield are generally kept in the middle of the years 80.
Parker Solar Probe's first phase of solar encounter began on October 31 and the probe will continue to collect scientific data until the end of the solar encounter phase on November 11. Several weeks after the end of the solar encounter phase before science the data begins to approach the Earth.
