ATREX mission creates glowing clouds

At 4:58 the first of 5 sounding rockets, 80 seconds apart, to study upper level winds were launched from the NASA Goddard Flight Center facility in Wallops Island, Virginia.  The target for this mission is the upper jetstream, 60 miles above the Earth.  Here windspeeds are 200-300 mph.  The rockets released a harmless chemical that, when combined with the oxygen in the atmosphere, glows.  This allows researches, using 3 cameras placed at the launch site, south in Duck, NC and north near Atlantic City, NJ, to build three dimensional models of these winds.
