IRIS aims to solve mysteries of the sun’s atmosphere - Rocket Launch [video]

They are also hoping that the mission will help explain the mysterious heat surge that solar particles undergo when they reach the chromosphere.

According to NASA, the sun's mass rises up from its core, the sun's hottest zone, and gradually lowers in temperature as it nears the surface. Then its temperature spikes again as it travels through the photosphere to the corona and, eventually, out into space. Astronomers agree that some unidentified process is conveying heat energy to the corona and, in turn, to the chromosphere. IRIS may help them figure out what it is.

Whatever is taking place in the corona and chromosphere, it makes a big difference for life on Earth. These interactions drive the solar wind and are responsible for most of the sun's ultraviolet radiation. The solar wind impacts Earth's atmosphere, creates the aurora borealis phenomenon, and occasionally interferes with radio transmissions here on our planet, while the ultraviolet energy is what makes Earth's climate hospitable to life.
