NASA is conducting experiments to "better understand the process responsible for the high-altitude jet stream located 60-65 miles (95-100km) above the surface of the Earth". Sounds boring? Watch the video and enjoy the (brief) show.
This morning, NASA's ATREX — Anomalous Transport Rocket Experiment — program launched five suborbital rockets from the space agency's Wallops Flight Facility in Virginia. The rockets fired 80 seconds apart, releasing a chemical tracer on the edge of space, 100km up in the sky. The chemicals created clouds that were seen from many miles away.
