If you aren't in the mid-Atlantic eastern seaboard, you can catch the aesthetically pleasing experiment via a NASA livestream slated to start at 8:30 pm ET. NASA will also open the visitor's center at Wallops if you'd prefer to be at the heart of the spectacle.
The glowing sky will be the result of NASA testing a new "ampoule ejection" system used to research the ionosphere and auroras. After launching the rocket, the team will send up ten canisters which will release blue-green and red vapor, known as vapor tracers, to create artificial clouds. (NASA says the tracers do not pose a risk to anyone on the ground.)
