There are many strange and ordinary lights in the sky. There are the stars, moon, planets and the Aurora Borealis for example. High in the sky, 60 to 65 miles above Earth’s surface, winds rush through a little understood region of Earth’s atmosphere at speeds of 200 to 300 miles per hour. Lower than a typical satellite’s orbit, higher than where most planes fly, this upper atmosphere jet stream makes a perfect target for a particular kind of scientific experiment: the sounding rocket. Some 35 to 40 feet long, sounding rockets shoot up into the sky for short journeys of eight to ten minutes, allowing scientists to probe difficult-to-reach layers of the atmosphere. When they go up, they will release materials that will be visible milky white clouds which will make the jet stream velocity and direction trackable. There will be a new light in the sky just off the US Atlantic coast.
