The released encounter data encompasses measurements made during the first two solar encounters, spanning the time between Oct. 31 and Nov. 12, 2018, and March 30 and April 19, 2019, when the spacecraft was within 0.25 AU of the Sun, as well as data collected at farther distances. One AU, or astronomical unit, is about 93 million miles, the average distance between the Sun and Earth. The mission will circle the Sun 25 times before it is expiring in 2025. Now it is on 3rd roll
