Probe dips into the sun's corona.
A quick update from NASA: the Parker Solar Probe has flown through the sun's upper atmosphere in the latest of a decreasingly distant number of passes around the sun, "sampling particles and magnetic fields." (An actual quotation, not scare quotes.) Apparently this is helpful in determining whence the solar winds, which happen when such flotsam reaches escape-grade parameters and flies outward rather than continuing to participate in the star's primary churn.
