A coronal mass ejection can cause problems on Earth. The energetic particles can damage satellites, cause communication and navigation problems in airplanes, and disrupt electrical power in homes and businesses. To understand the Sun and its effects on Earth, NASA has 17 missions, including STEREO, observing the Sun. On February 11, 2010, the fleet grew by one when NASA launched its most advanced solar spacecraft, the Solar Dynamics Observatory, to study the causes of solar variability and its impacts on Earth.
