In the days before Parker Solar Probe (PSP), the previous record-breaking spacecraft for speed and closest distance to the Sun were the two Helios probes, launched in the mid-1970s. Now with PSP re-entering the environment inward of the orbit of Mercury, data from these probes is being re-examined with newer tools and compared to the newer data.
