NASA launches IRIS spacecraft on Pegasus rocket to study sun’s energy

NASA has launched a spacecraft that will study the sun and how its fluctuating and intense heat affects Earth’s atmosphere. IRIS, a 7-foot-long craft mounted to the nose of a Pegasus rocket, blasted off into space after being carried up on an airplane. The Interface Region Imaging Spectrograph will look at the region of sun that lies between the surface and the outer atmosphere called the corona. Scientists hope it will provide clues as to where most of the sun’s ultraviolet emission is generated that impacts Earth’s climate. Report by Ashley Fudge.
