The objects created by humanity break existing records and come closest to the sun.

NASA has announced that NASA's "Solar Solar Probe" solar access probe, launched in August, has reduced its distance from the sun's surface to 42.73 million kilometers at 13:04 (ETH). ;Is) . This distance is the distance at which Helios 2, the solar probe, jointly developed by Germany and the United States in 1976, was the closest.

NASA also announced that the Parker Solar Probe had crossed the border at 22,669 km / h at 22:54 the same evening, the speed at which Helios 2 accelerated the fastest. This speed is around 265,000 km / h, the highest speed ever built by Jupiter, the fastest man ever created by Jupiter.

The Parker Solar Probe observes the Sun seven times above Venus in overflight (using a gravity, such as a planet, to jump like a spring and change direction or direction). In this process, the closer the sun is, the faster the speed. After the last overflight in 2025, the distance to the sun's surface is reduced to 6.16 million km and, because of the gravitational force of the sun, the speed accelerates and the maximum speed should reach 690 000 km per hour (192 km per second).

The Parker Solar Probe has 24 solar access missions by 2025. The current approach is the first solar access mission. The first close mission begins on the 31st of this month and goes through the perihelion (nearest point of the sun) at 22:28 on November 5 (US local time). At this point, the distance to the sun should be 25 million km. After that, we approached the sun about every 150 days, then proceeded gradually to the approach cycle, before approaching the sun 88 days apart and completing the mission.

When the Parker Solar probe approaches the sun, solar energy reaches 475 times the Earth's maximum. The Parker Solar Probe is designed to withstand heat by using a carbon shielding film less than 11 cm in thickness to prevent this. It can withstand temperatures up to 1370 degrees.
