CAPE CANAVERAL, Florida, July 1: A small NASA telescope was launched into orbit on Thursday on a mission to determine how the sun heats its atmosphere to millions of degrees, sending off rivers of particles that define the boundaries of the solar system. The study is far from academic. Solar activity directly impacts Earth’s climate and the space environment beyond the planet’s atmosphere. Solar storms can knock out power grids, disrupt radio signals and interfere with communications, navigation and other satellites in orbit. (agencies)
