The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [6] is a NASA space probe launched in 2018 to make observations of the Sun's outer corona. It used repeated gravity assists from Venus to develop an eccentric orbit, approaching within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ] [ 8 ] from ...
The Parker Solar Probe zoomed by the sun on Tuesday during a record-breaking flyby, coming within 3.8 million miles (6.1 million kilometers) of the solar surface during humanity’s closest ...
English: Parker Solar Probe has now “touched the Sun”, passing through the Sun’s outer atmosphere, the corona for the first time in April 2021. The boundary that marks the edge of the corona is the Alfvén critical surface.

IS☉IS hardware being prepared for its mission, EPI-Lo hardware shown in 2017. Integrated Science Investigation of the Sun or IS☉IS, is an instrument aboard the Parker Solar Probe, a space probe designed to study the Sun. IS☉IS is focused on measuring energetic particles from the Sun, including electrons, protons, and ions. [1]
NASA's Parker Solar Probe is intended to approach the Sun to a distance of approximately 9.5 solar radii to investigate coronal heating and the origin of the solar wind. It was successfully launched on August 12, 2018 [ 36 ] and by late 2022 had completed the first 13 of more than 20 planned close approaches to the Sun. [ 37 ]

Researchers were unsure exactly where the Alfvén critical surface of the Sun lay. Based on remote images of the corona, estimates had put it somewhere between 10 and 20 solar radii from the surface of the Sun. [5] On April 28, 2021, during its eighth flyby of the Sun, NASA's Parker Solar Probe (PSP) encountered the specific magnetic and particle conditions at 18.8 solar radii that indicated ...
