This Final Venus Flyby Will Propel Parker Probe Toward a Record-Breaking Encounter With the Sun

NASA’s Parker Solar Probe volition marque its seventh and last flyby of Venus tomorrow, capitalizing connected our next-door-neighbor’s gravitational propulsion to fling the probe backmost towards the Sun.

When the probe gets to the Sun, it volition go the closest immoderate human-made entity has travel to the aboveground of our star. The flyby sets the probe up to execute that feat, and is an accidental to bespeak connected the grade of Parker’s revelations astir Venus, from the ringing of dust astir the satellite to the intriguing vigor signals from its atmosphere.

At its closest attack during the gravity assist, the probe volition walk wrong 233 miles (376 kilometers) of Venus’ surface. In that maneuver, the probe volition alert astir Venus, leveraging the gravitational unit the satellite exerts connected the spacecraft to motorboat itself towards the Sun. Gravity assists are a useful instrumentality for abstraction agencies aiming to minimize the substance spacecraft request to transportation and burn.

The Parker Solar Probe has had erstwhile adjacent shaves with the Sun. In 2021, the probe flew done a coronal wide ejection—an outburst of particles and radiation from the aboveground of the star—and captured immoderate wicked video of that utmost environment. The probe did the same successful September 2022, helping researchers recognize however the Sun’s plasma interacts with the interplanetary particulate astir it.

Flybys supply an accidental to representation the aboveground of worlds up-close. During flybys successful 2020 and 2021, the probe snapped images of the Venusian aboveground that corresponded with information collected by the intrepid Magellan spacecraft 30 years earlier. The Parker probe took its images with its Wide-Field Imager, oregon WISPR, which revealed infrared emissions from the planet’s surface, which glows truthful blistery that the WISPR cameras could spot the emissions done the planet’s dense clouds.

“Because it flies implicit a fig of akin and antithetic landforms than the erstwhile Venus flybys, the Nov. 6 flyby volition springiness america much discourse to measure whether WISPR tin assistance america separate carnal oregon adjacent chemic properties of Venus’ surface,” said Noam Izenberg, a abstraction idiosyncratic astatine the Johns Hopkins Applied Physics Laboratory, successful a NASA release.

When Parker makes its closest attack of the Sun, it volition beryllium wrong 3.86 cardinal miles (6.12 cardinal kilometers) of the star’s surface. The near-pass, which volition spot the probe alert done plumes of plasma spewing disconnected the Sun astatine a grounds 430,000 miles per hour (692,000km/hr), is the probe’s last objective.

The closest attack is scheduled to hap connected December 24, during which the probe volition beryllium retired of interaction with ngo control. But according to the aforesaid release, the probe volition transmit a beacon connected December 27 to notify ngo power of its occurrence and condition.

The Parker Solar Probe ngo is scheduled to extremity successful 2025, aft this dramatically adjacent walk of our star. Whatever comes aft it volition beryllium connected the shoulders of a record-breaking elephantine successful spaceflight.
