The two mysteries prompting this mission are the high temperature of the sun's corona and the puzzling acceleration of the solar wind:

Mystery #1—the corona: If you stuck a thermometer in the surface of the sun, it would read about 6000o C. Intuition says the temperature should drop as you back away; instead, it rises. The sun's outer atmosphere, the corona, registers more than a million degrees Celsius, hundreds of times hotter than the star below. This high temperature remains a mystery more than 60 years after it was first measured.

Mystery #2—the solar wind: The sun spews a hot, million mph wind of charged particles throughout the solar system. Planets, comets, asteroids—they all feel it. Curiously, there is no organized wind close to the sun's surface, yet out among the planets there blows a veritable gale. Somewhere in between, some unknown agent gives the solar wind its great velocity. The question is, what?

This is one ultra COOL mission

Hopefully they'll be able to collect alot of interesting information about why the solar wind and the corona temperature both seem to defy logic.

Industry uses electromagnets to heat up metal (induction) so I wonder if that might be part of the process going on away from the surface?

Or a "greenhouse" type effect where some of the sun's radiant energy is being held and concentrated above the surface.

It will be interesting to see if we can find out.
