6 "Parker" rushes to explore the solar wind – Parker, Earth, slow, scientist, himself – Technology Daily

Despite the delay in launch, people are still waiting for the good news that Parker was successfully launched. On August 12, Parker Solar Detector was launched at Cape Canaveral Air Force Base. "Parker" is closer to the sun than before, and is expected to play a decisive role in the study of various scientific problems.

In addition to providing light and geothermal energy, high-speed plasma flow called "solar wind" flows from the surface of the sun and flows into the depths of the solar system. When it reaches the Earth, it interacts with the Earth's magnetic field.

In the sun's corona, the plasma temperature of the sun's atmosphere has surged from more than 6,000 degrees Celsius to millions of degrees Celsius. "Parker" will go far to the place where the sun's heat and the acceleration of the solar wind actually occur, and look for abnormally high sundial temperatures.

Scientists have confirmed that fast solar winds at speeds of 450-850 km / s are from caves. However, there is still controversy about where the solar wind is slow at speeds of 250-450 km / s coming from. The "Parker" observation will help scientists find out the origin of the solar wind.

After seven Venus flights, Parker Solar Detector will eventually reduce the altitude of its orbit to less than nine solar radii in seven years, reaching the detection goal near Sundial in the last three rounds.
