For the first time, NASA, the U.S. space agency, has handed over the reins of one its spacecraft to a group of ordinary people. The International Sun Earth Explorer 3 was launched in 1978 to study space weather and collect data on the streams of particles flowing from the sun. Those particles, also known as solar wind, can damage satellites, interrupt radio signals and knock out electric systems that power our homes. Rosanne Skirble reports.
