"The corona is also constantly releasing a stream of charged particles known as the solar wind.
But this isn't the kind of wind you can fly a kite in.
Even the slowest moving solar wind can reach speeds of around 700,000 mph. And while scientists know a great deal about solar wind, the source of the slow wind remains a mystery."

"The solar wind is now know to be a mixture of materials found in the solar plasma, composed of ionized hydrogen (electrons and protons) with an 8% component of helium and trace amounts of heavy ions. The solar wind has been detected inward toward the sun to the orbit of Mercury, and outward past the orbits of Uranus and Neptune."

"The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. The composition of the solar wind plasma also includes a mixture of materials found in the solar plasma: trace amounts of heavy ions and atomic nuclei such as C, N, O, Ne, Mg, Si, S, and Fe. There are also rarer traces of some other nuclei and isotopes such as P, Ti, Cr, 54Fe and 56Fe, and 58Ni, 60Ni, and 62Ni."

"Beyond gases, there’s another state of matter called plasma. And it makes up 99.9% of the observable universe. This is completely different from plasma in our blood. We’re talking about a state of matter, that’s similar to a gas but with different properties."

"If spacetime is a fluid, then according to our calculations it must necessarily be a superfluid.
‘This means that its viscosity value is extremely low, close to zero."

"There are multiple types of drag that one may experience during a flight operation, and each differs in its source and characteristics. As a pilot will regularly face all types of drag during their career, it can be extremely beneficial to be aware of each type and their cause.
Parasite Drag
Parasite drag is a common type, resulting from the movement of an object through a fluid such as atmospheric air."
