Parker Solar Probe launched in 2018, heading to the centre of our solar system. It has already swept past the Sun 21 times, getting ever nearer, but the Christmas Eve visit is record-breaking.
The spacecraft passed 3.8 million miles (6.1 million km) from the solar surface on Dec. 24, flying into the sun's outer atmosphere called the corona, on a mission to help scientists learn more ...
Within two months of launching, the Parker Solar Probe in October 2018 moved within 26.55 million miles of the sun's surface, breaking the previous mark set by the Helios-2 spaecraft in 1976.
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 ...
Polarimeter to Unify the Corona and Heliosphere (PUNCH) is a future mission by NASA to study the unexplored region from the middle of the solar corona out to 1 AU from the Sun. PUNCH will consist of a constellation of four microsatellites that through continuous 3D deep-field imaging, will observe the corona and heliosphere as elements of a ...
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 ...
NASA's Parker Solar Probe is about to make its closest approach to the sun. The spacecraft will fly within 3.8 million miles of the solar surface. The spacecraft is collecting essential data that ...
