Parker Solar Probe
21 The Parker Solar Probe is getting closer to the Sun than ever before, with an ambitious plan to ‘touch’ the outer corona. The probe is designed to be highly automated as radio contact will take eight minutes, and the spacecraft will need to react more quickly to sudden changes in the Sun’s output.
Its goals are to track the flows of energy within the Sun that heat its corona and power the solar wind. It hopes to determine the structure of the Sun’s magnetic field, and determine how energetic particles are accelerated. Its orbits around the Sun will cross those of Mercury and Venus, and the probe will make seven flybys of Venus as it shrinks its orbit to get closer to the Sun.
