The Parker spacecraft is the first spacecraft to enter the outer atmosphere of the sun, known as the ‘crown’, an event that occurred in April 2021. The probe collected information about the sun and the ‘The sun wind”. It was able to photograph the sun from a distance of 27 million km, about 122 million km closer to the Earth’s location.
