Despite the postponement of the launch, people were still waiting for the good news that Parker was successfully launched. On August 12th, Parker's sunlight detector was released at the Cape Canaveral Air Base. "Parker" is closer to the sun than ever before, and is expected to play a decisive role in studying more scientific issues.
In addition to giving light and heat on Earth, at high speed, a plasma current called the "sunny wind" moves from the surface of the sun and moves to the depths of the solar system. When it reaches Earth, it will communicate with the magnetic field on Earth.
In the solar corona, the plasma temperature of the sun's atmosphere has risen from more than 6,000 degrees Celsius to millions of degrees Celsius. "Parker" will go deep in the place where the heat of the sun and the acceleration of the solar wind will indeed occur, and will seek the abnormal high temperature of the probe.
Scientists have confirmed that the rapid solar wind at a speed of 450-850 km / s originates from the cave. However, there are still controversies about where the slow solar wind is coming at a speed of 250-450 km / s. Parker's observation will help scientists find out about the origin of the solar wind.
After seven Venus flights, Parker's solar detector would ultimately lower its orbital altitude to less than nine solar radii in seven years, achieving the goal of near-probe detection in the last three laps.
