Nighttime clouds shed light on space weather
NASA is looking for the opportunity, beginning Monday, to launch rocket experiments that will form nighttime clouds in a project intended to shed light on space weather. Three of the four rocket experiments, launched from the NASA Wallops Flight Facility, Virginia, will include the formation of milky, white clouds. The clouds will allow scientists to view winds in a high and poorly accessible layer of Earth's atmosphere called the ionosphere.
