The tip of the Parke detector is 15 million miles away from the sun's surface.
The Parke solar probe is also the current "double world record holder". The "phase one" of meeting the sun (starting on October 31) will continue to collect data until November 11.
The Parke detector has a mandate of seven years. On April 4, 2019, it will once again return within 15 million miles of the sun to conduct a closer study of the star.
