NASA’s Parker Solar Probe Makes Final Venus Flyby Before Historic Sun Encounter

NASA’s Parker Solar Probe will make a detailed method to Venus on Wednesday, marking the spacecraft’s seventh and last flyby of the planet. This manoeuvre will set the probe on a course for its historic plunge towards the solar, bringing it inside 3.8 million miles of our star’s floor — nearer than any human-made object has ventured. Nour Raouafi, Project Scientist on the Johns Hopkins University Applied Physics Laboratory, described this method as “nearly touchdown on a star,” likening it to the importance of the 1969 moon touchdown.

Venus Flybys as Critical Milestones

The Parker Solar Probe, launched in 2018, depends on gravitational assists from Venus to regularly scale back its distance from the solar, utilizing the planet’s gravitational pull to regulate its orbit. Yanping Guo, Mission Design and Navigation Manager on the Johns Hopkins Applied Physics Laboratory, emphasised that this last Venus flyby is essential in positioning the probe for its upcoming shut encounter with the solar.

While designed for photo voltaic exploration, the probe’s devices have offered precious knowledge on Venus. During earlier flybys, Parker’s Wide-Field Imager (WISPR) managed to seize pictures by way of Venus’s thick ambiance, revealing floor particulars like continents and plateaus. The probe additionally recorded emissions from Venus’s nightside, offering insights into its floor composition and temperature, which is round 860 levels Fahrenheit (460 Celsius).

A Closer Look at Venusian Surface

This week’s flyby will enable scientists to level WISPR towards Venus as soon as extra to seize new floor pictures, together with areas with diverse landforms. Noam Izenberg, a planetary geologist at APL, famous that this shut method provides a novel likelihood to review variations in Venus’s floor options, doubtlessly uncovering details about its geology and thermal properties.

Approaching the Sun’s Frontier

On December 24, the Parker Solar Probe will skim the solar’s outer layer at speeds of as much as 430,000 miles per hour (692,010 km/h). Although mission management will lose contact throughout this shut move, engineers hope to obtain a sign on December 27 confirming the probe’s success. This achievement may unlock important insights into the solar’s outer ambiance, its intense warmth, and its magnetic dynamics, additional advancing our understanding of photo voltaic phenomena.
