This July, scientists will launch four rockets from NASA's Wallops Flight Facility, Va., for a five-minute journey some 100 miles up into the atmosphere. The rockets will collect data on the charged particles as well as winds of neutral particles that sweep through the lower ionosphere and how each affects the other, ultimately causing these dynamo currents. The variations matter because all of our communications and GPS satellites send signals through the ionosphere. A disturbed ionosphere translates to disturbed signals, so scientists want to know just what causes the ionosphere to behave in specific ways. Read more
Two NASA Terrier-Improved Orion and Black Brant V sounding rockets will be launched from the Wallops launch site. The launch window is 9:30 a.m. to 1 p.m. (Local time).
