Nasa is set to make a major announcement about its first mission “to touch the sun”.The Solar Probe Plus spacecraft is set to take off in 2018 NASA’s Goddard Space Flight Center/SDO/Joy Ng, producer
The agency wants to send a spacecraft closer to the sun than ever before, where it will face extreme temperatures and radiation levels.
I think this might be relevant to this thread.Solar Probe Plus will plunge directly into the sun’s atmosphere at approximately 4 million miles from the sun’s surface into a region that no other spacecraft has ever encountered. The spacecraft folds its solar panels into the shadows of its protective solar shade, leaving just enough of the specially-angled panels in sunlight to provide power closer to the sun.
The experiments selected for Solar Probe Plus are specifically designed to solve two key questions of solar physics - why is the sun's outer atmosphere so much hotter than the sun's visible surface and what propels the solar wind that affects Earth and our solar system? " said Dick Fisher, director of NASA's Heliophysics Division in Washington.
