Parker’s ground team found out soon after launch that the probe is capable of a higher downlink rate. In fact, they’re taking advantage of that ability by instructing the probe to send back even more data from the second encounter in April. During that event, the spacecraft’s four suites of science instruments kept busy collecting information. That’s why the mission team is expecting to receive an additional 25GB of science data between July 24th and August 15th.
The mission team will release the data from the first two encounters to the public later this year. Before that happens, the spacecraft will conduct its third flyby, which will start on August 27th and reach closest approach on September 1st. Researchers are hoping that over the net few years the mission can gather the information we need to unravel some of the sun’s biggest mysteries, including why the sun’s corona (its aura of plasma) is far hotter than its visible surface.
