According to the National Aeronautics and Space Administration (NASA) official website, NASA's Parker Solar Probe arrived at 26.55 million miles (42.73 million kilometers) from the Sun at 1:04 am on the 29th of the US Eastern Daylight Time. ), becoming the man-made object that has so far been in close contact with the sun.
The previous record from the Sun was created in April 1976 by the Helios 2 probe developed by Germany and the United States. As the "Parker" solar mission continues, the spacecraft will continue to break its record. Eventually, Parker's closest distance to the Sun is only 3.83 million miles, which is expected to be achieved in 2024.
"Parker" project manager Andy Delhisman said: "The 'Parker' solar probe took off only 78 days and became the closest spacecraft to date. For us, this is A moment to be proud of."
In addition, the "Parker" solar probe also broke the fastest spacecraft record relative to the sun. This previous speed record was 153,454 mph, also set by the "Sun God 2" probe in April 1976. The Parker project team uses NASA's Deep Space Network (DSN) to regularly measure the exact speed and position of the spacecraft. The DSN sends a signal to the spacecraft, which then sends it back to the DSN, allowing the team to determine the speed and position of the spacecraft based on the time and characteristics of the signal.
On the 31st, "Parker" will begin its first "meeting" with the Sun, which will continue to fly closer to the surface of the sun until it reaches the first point of the sun (closest to the sun) The point is about 10:28 pm on November 5th in the US Eastern Daylight Saving Time.
Although the spacecraft will face the sun's roasting and harsh radiation environment, it will provide humans with an unprecedented close-up view of the sun and help us understand the phenomena that have plagued scientists for decades. For example, why the sundial is much hotter than the sun's surface, how the sun's magnetic field is generated, etc., and uncovers the true wind of the sun. (Reporter Liu Xia)
