The solar probe was "alive" after it was closest to the Sun: NASA



Parker Solar Probe, a NASA mission to solve the mystery of the Sun, is alive and well after the imitation of the Sun at just 15 million miles from its surface.

This is much closer than any spacecraft that has already departed – the previous record was designated by Helios B in 1976 and broken by Parker on October 29 – and this maneuver highlighted the spacecraft with intense heat and solar radiation in a complex solar wind environment, NASA said in a statement on Thursday.

On November 5, the space ship made the closest approach, called perihelion. Parker Solar Probe reached its highest speed of 213,200 miles per hour, setting a new speed record for spacecraft.

At this distance, intense sunlight was heated by the sun at the side of the thermal shield Probe, called the thermal protection system, at about 820 degrees Fahrenheit.

This temperature will rise to 2,500 Fahrenheit when the spacecraft approaches the Sun, said NASA.

"Parker Solar Probe has been designed to take care of itself and its precious benefit with this close approach, without control from us on Earth – and now we know it has succeeded," said Thomas Zurbuchen, associate administrator of the NASA Science for Science Washington.

On November 7, mission controllers at Johns Hopkins Applied Physics Lab received a status lighthouse from a spacecraft at 4:46 AM. (EST).

The signal has marked the status "A" – the best of the four possible status signals, which means that Parker Solar Probe works well with all the instruments that run and collect scientific data, and if any minor problems have occurred, they have been solved solely by spacecraft .

"Parker is the culmination of 60 years of scientific advancement. We have now come to know our first visit to neighboring humanity, which will have consequences not only on Earth, but also for a deeper understanding of our universe," added Zurbuchen.

The first stage of the solar probe Parker Solar Probe began on October 31, and the spaceship will continue to collect scientific data by 11 November, until the end of the solar winding phase. Only a few weeks after the end of the phases of the sunset before the start of scientific data, descending to the Earth.

Space ship will repeatedly break its own speed record when its orbit approaches the star, and the space ship travels faster and faster in perihelion, NASA said.
