Glowing Clouds On Their way to Space

This is gorgeous:
"Three rockets launched from the NASA Wallops Flight Facility, Wallops Island, Va., will release a chemical called trimethylaluminum (TMA) into the air 90 km to 175 km above the Atlantic Ocean. TMA burns spontaneously in the presence of oxygen. The harmless by-products of this glowing reaction will be visible from coastal Virginia, North Carolina, Maryland, New Jersey, Washington DC, and possibly parts of lower New York and Pennsylvania."
