Plunging into the sun

NASA is working on a mission called Solar Probe Plus that will delve deeply into the sun's atmosphere in an attempt to answer two long-standing questions: why the sun's outer atmosphere, or corona, is about 2 million degrees Fahrenheit hotter than its surface, and why solar wind seems to have no organizing force.

Scientists hope the mission launches in 2015 Sweet!
