Successful Ninth Solar Flyby for Parker Solar Probe

On Aug. 13, 2021, at 5:50 a.m. EDT, mission controllers at the Johns Hopkins University Applied Physics Laboratory, in Laurel, Maryland, received a “tone one” beacon from Parker Solar Probe, indicating that all systems were healthy and operating normally after the spacecraft’s ninth close approach to the Sun on Aug. 9.

During this close pass by the Sun — called perihelion — Parker Solar Probe matched its own records for spacecraft distance from the Sun and speed, coming to within about 6.5 million miles (10.4 million kilometers) of the Sun’s surface, while moving faster than 330,000 miles per hour (532,000 kilometers per hour).

Science data collection for this solar encounter continues through Aug. 15.
