Subsequent missions will analyse the solar wind, three comets and the planet Mercury.
Also, changes in the speed and pressure of the solar wind cause the termination shock to expand, contract and ripple.
Genesis had painstakingly deployed the collector tiles and foil over the last two years to capture atoms from the solar wind.
As a result, it is bombarded by the solar wind and this might have resulted in the loss of water and oxygen.
In addition to these goodies, the solar wind carries light elements such as helium to the moon's surface and leaves them there.
During a short cycle the solar wind (a breeze of electrically charged gas blowing off the sun's surface) is stronger than normal.
An analysis of the solar wind is expected to provide clues about the composition of the sun and origins of our solar system.
On its own, the pressure exerted by the protons and electrons of the solar wind is even more feeble than the photon pressure.

Instead of relying on photon pressure, it would enable a spacecraft to be pushed along by the charged particles of the solar wind itself.

When the sun is at its most active, which is when it is spotty, the solar wind is stronger and fewer cosmic rays penetrate.
Understanding exactly what the Geotail does (something to do with measuring the solar wind's interaction with the Earth's magnetosphere) may require a background in heliophysics.
These craft will study the interaction between the solar wind (the breeze of electrically charged particles emitted by the sun) and the earth's magnetic field.
And when the solar wind is stronger, it is better at shielding the earth from high-energy charged particles from outer space known as cosmic rays.
Effects stemming from the Earth's atmosphere, from ocean tides and from the solar wind of charged particles were all found to be too small to explain the spacecrafts' extra velocity.
The most persuasive evidence that Voyager 1 has crossed the termination shock is its measurement of a sudden increase in the strength of the magnetic field carried by the solar wind, combined with an inferred decrease in its speed.
There will also, according to Charlie Bolden, NASA's administrator, be a mission to the sun, to study the solar wind, and one to improve the agency's ability to detect and catalogue interesting (but potentially dangerous) asteroids that pass near Earth.

How big would the solar, wind and nuclear facilities need to be to supply this halved consumption?
The solar and wind power segments are especially well represented.
Given the likely direction of the new GOP-dominated House of Representatives in Washington, massive federal subsidies for the solar and wind industries, as well as such boondoggles as high-speed rail, are likely to be scaled back significantly.

As a result, a system using wind and solar has to be built with sufficient system capacity from conventional sources to be handle the system full load without the wind and solar systems.

Indeed, various companies, including GE, are investing heavily in ways to come up with cost-effective systems to store the wind and solar energy that their wind turbines and solar technologies capture in combination with other means of generating electricity and power.

Well, how about investment in clean energy so that the solar panels and wind turbines and electric cars are built here in the United States?
At issue is the production tax credit provided to wind and solar energies, although the one for wind is set to expire in December.
It also says that many of the unregulated power generators will need to broaden their fuel options, meaning they will look for other participants not just in the natural gas area but also in the wind, solar and hydro sectors.

Today we have roughly 40 percent of our electricity is in clean energy, if you consider the nuclear, the wind, the solar -- natural gas counting half credit.
But the pending expiration of a crucial incentive, the federal Production Tax Credit, is likely to bring the wind boom and any future hybrid wind-solar projects to a halt unless Congress extends the subsidy that pays producers a premium for each kilowatt-hour they generate.

The thing is that the more solar panels and wind-turbines that are installed, the more the bill rises.

It is making substantial investments in a renewable energy, and is now the largest solar, wind, nuclear and hydropower market.
