Before sunrise on March 27th, sky watchers up and down the eastern seaboard of the United States witnessed a strange apparition. A quintet of milky-white plumes appeared in the night sky, twisting in the winds at the edge of space. The plumes were chemical tracers (trimethyl aluminum) deposited in the upper reaches of Earth’s atmosphere by five rockets launched rapid-fire from NASA’s Wallops Flight Facility in Virginia. The goal of the experiment, named ATREX (Anomalous Transport Rocket Experiment), is to study 3D turbulence in the thermosphere.
