NASA is planning a launch of an Interface Region Imaging Spectrograph, or IRIS satellite, to better observe the sun. The satellite is designed for close-up observations of the surface of the sun, but will only be able to see 1 percent of it at a time and resolve features just 150 miles (240 km) across the surface. The satellite, measuring 7 feet high (2.1 meters) and 12 feet across (3.7 meters), will orbit Earth in a polar, sun-synchronous path that will take it over the equator at the same local time each day.
