The American space agency announced that the Parker probe had passed as close as possible to the most important star in the solar system on Tuesday, December 24.
NASA signs a new space exploit at Christmas time. According to the BBC, the Parker probe, launched into space in 2018, came closest to the Sun on Tuesday, December 24. A feat which is not insignificant for this device which has already had the opportunity to come close to the star 21 times, reports BFMTV.
But this time, Parker set a new proximity record by coming close to six million kilometers from the surface of the Sun. A figure that seems distant. For comparison, the Earth is located 93 million kilometers from the Sun, explains Nicola Fox, responsible at NASA, to the BBC. Thus, if we placed ourselves one meter from the Sun, the Parker probe would in fact be only four centimeters from the star, adds the source.
Average speed: 690,000 km/h
For the moment, Parker's passage near the Sun has not yet been analyzed by the American space agency. NASA explains that it lost contact with the probe due to its attraction to the Sun for several days, and hopes to have a first signal this Friday. “This is an example of NASA's bold missions, accomplishing something no one has ever done before to answer long-standing questions about our universe,” program scientist Arik Posner said in a statement. Parker Solar Probe.
With an average speed of 690,000 km/h, the ship faces incomparable heat on Earth. According to BFMTV, the probe endured temperatures between 870 and 930 degrees. However, the internal instruments of the device were kept at an ambient temperature of approximately 29°C. One of Parker's main goals is to understand why the outer part of the Sun, called the corona, is two hundred times hotter than the rest of the body.
