Solar wind
Wikipedia, the free encyclopedia - Cite This Source
The solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of the sun.

The Solar Wind
"Plumes" of outward flowing, hot gas in the Sun's atmosphere may be one source of the solar "wind" of charged particles.

Solar wind (stream of particles from the Sun) is usually around 0.001 joules per square meter per second -- about a million times less than sunlight.

It takes the solar wind about 4.5 days to reach Earth; it has a velocity of about 250 miles/sec (400 km/sec). Since the particles are emitted from the Sun as the Sun rotates, the solar wind blows in a pinwheel pattern through the solar system.

SOLAR WIND - Supersonic flow of high-speed charged particles continuously blowing off a star (mostly e- and p+). When originating from stars other than the Sun, it is sometimes called a "stellar" wind.

Solar wind--hot solar plasma spreading from the solar corona in all directions, at a typical speed of 300-700 km/sec. It is caused by the great heat of the corona.

Streams of charged particles flowing from the Sun at millions of kilometers an hour. The composition of this high-speed solar wind may vary, but it always streams away from the Sun.

Solar Winds
As the Sun burns hydrogen at its core, it releases vast amounts of atomic particles, or pieces of atoms into outer space. These atomic particles, along with the Sun's radiation create a sort of wind, known as the solar wind.

The solar wind (heliospheric) termination shock is the shock that occurs as the solar wind hits the and its speed slows greatly (down to about 20 km/s).

The solar wind has an electron density of about 5 per cc over path lengths of about 150 million km giving an even greater optical depth. This would not affect moonbounce work but would make VHF radio astronomy impossible.

The solar wind has large effects on the tails of comets and even has measurable effects on the trajectories of spacecraft.
Spectacular loops and prominences are often visible on the Sun's limb (left).

The solar wind is not the major problem for a trip to Mars - shielding agains that is easy enough with a few cms of perspex or a few mm of Al. The real challenge is high-energy cosmic rays.

The corona is also the source of the solar winds, steady streams of particles that are blown off from the Sun. These particles can on occasion interact with the Earth's atmosphere and produce the aurora, or northern lights.

The issue of the solar wind eroding the atmosphere of a terraformed Mars has not been addressed in detail, because it is still unclear whether humans have the economic means to terraform Mars.

I remember a news flash earlier that day from SpaceWeather that one of NASA's spacecraft detected a sudden increase in particle density and speed of the solar wind.

It was reasoned that the apparent motion of the pulsar was actually due to the modulation of the solar wind in that direction.
