The Parker Solar Probe concept originates in the 1958 report by the Fields and Particles Group, Committee 8 of the National Academy of Sciences' Space Science Board, [19] [20] [21] which proposed several space missions including "a solar probe to pass inside the orbit of Mercury to study the particles and fields in the vicinity of the Sun". [22 ...

It is orbiting at about 1.5 million km from Earth in a halo orbit around the Lagrange point 1 (L1) between the Earth and the Sun, where it will study the solar atmosphere, solar magnetic storms, and their impact on the environment around the Earth. [7] It is the first Indian mission dedicated to observe the Sun. Nigar Shaji is the project's ...

SOLAR-C (official name "High-sensitivity Solar Ultraviolet Spectroscopic Satellite" [1]) is a planned Sun-observing satellite being developed by the Japan Aerospace Exploration Agency (JAXA), the National Astronomical Observatory of Japan (NAOJ), and international collaborators.
Comparison of HMI Continuum images immediately after an eclipse, and then after the sensor has re-warmed. The Helioseismic and Magnetic Imager (HMI), led from Stanford University in Stanford, California , studies solar variability and characterizes the Sun's interior and the various components of magnetic activity.
These types of satellites are almost always in Sun-synchronous and "frozen" orbits. A Sun-synchronous orbit passes over each spot on the ground at the same time of day, so that observations from each pass can be more easily compared, since the Sun is in the same spot in each observation.
