Short Maneuver Targets Parker Solar Probe for Venus Flyby

On Sept. 29, NASA’s Parker Solar Probe completed a small maneuver that refined its path for a flyby of Venus in two weeks.

The maneuver, monitored from the mission operations center at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, lasted just five seconds and trimmed the spacecraft's velocity by 9.7 centimeters per second, or less than a quarter of a mile per hour. But it was critical for keeping Parker Solar Probe on pace for its next pass by Venus, on Oct. 16, when it will use the planet's gravity to swing toward its 10th close approach to the Sun.

Parker Solar Probe, which was designed and built at APL, is healthy and its systems are operating normally. The spacecraft completed its ninth solar encounter on Aug. 15, at closest approach coming within 6.5 million miles (10.4 million kilometers) of the Sun's surface. The upcoming Venus gravity assist will send the spacecraft even closer to the Sun’s blazing surface – about 5.3 million miles (8.5 million kilometers) -- on Nov. 21.

Assisted by two additional Venus flybys, Parker Solar Probe will eventually come within 4 million miles (6.2 million kilometers) of the solar surface in late 2024.
