Corona is the outermost layer of Sun’s atmosphere. Here, strong magnetic fields bind plasma as well prevent turbulent solar winds from escaping.
Prior to April 28, spacecraft had been flying just beyond the Alfven point.
The Alfven point is when solar winds become greater than critical speed and can break free of Sun’s corona and magnetic fields.
Parker Solar Probe is a NASA space probe. It was launched on August 12, 2018. It was launched with objective of making observations of outer corona of the Sun. It reached to within 9.86 solar radii from Sun’s center. By 2025, it will travel at closest approach. It is the first spacecraft to fly into low solar corona
