Space probe "Parker" aerospaceNASA is in space for only about two and a half months, but is already breaking records. The device approached a distance of 42.73 million kilometers to the surface of the Sun, becoming the probe closest to our luminary in history. Previously, this record belonged to the German-American probe Helios 2, which set it in April 1976. In addition, Parker broke another record, developing a maximum speed relative to the Sun - above 246 960 kilometers per hour.
Recall that at the moment the title itselfThe fast-moving spacecraft relative to the Earth belongs to the Juno probe - its speed is 265,000 kilometers per hour. By the end of his mission, Parker worth $ 1.5 billion will be able to break this record.
Recall that the main task of the apparatusis to study the solar corona. To do this, he will make 24 rounds of our luminary within 7 years, getting closer and closer to the star. The last flyby of Parker around the Sun should take place in 2025. At this point, the device will be located at a distance of only 6.16 million kilometers from the surface of the Sun. According to NASA experts, the powerful gravity of the star will ultimately be able to accelerate the probe to a speed of about 690,000 kilometers per hour.
Preparations for the first flyby around the Sun will begin on October 31. The device will reach perihelion (the nearest point from the object) on November 5th.
“Only 78 days have passed since the launchof the Parker solar probe, but we have already approached our Sun as much as no spacecraft in history has approached the sun. This is a momentous moment for our team. Now we are completely focused on our first flyby around the Sun, which we will start on October 31, ”comments Andy Drysman, head of the Parker program from the Johns Hopkins University Laboratory of Applied Physics.
The solar probe is equipped with a special carbona composite shield that protects the apparatus itself and its scientific devices from direct exposure to solar heat and radiation. In addition, the device has on board many scientific instruments for researching our luminary. The probe will allow scientists to better understand the structure of the Sun, its composition, as well as activity. Thanks to these data, scientists want to solve two very old puzzles. The researchers are interested in why the temperature of the outer atmosphere of the Sun (corona) is much higher than its surface, as well as the reason for the acceleration of charged particles of the solar wind to incredibly high speeds.
