Wallops Island, VA (WVNS) — NASA is planning to launch a rocket from their Wallops Island launch pad on May 7, 2021. The Black Brant XII rocket being launched is part of a research project studying how energy is transported in space. As part of the study, a cloud of vapor is set to be released during the flight that may be visible along the east coast. Additional launch windows are scheduled through May 16 in case this launch is canceled due to weather.
The launch window for the May 7 flight opens at 7:58 pm EDT and closes at 8:38 pm EDT. Approximately nine and a half to 10 minutes into the flight, at an altitude of 200+ miles, the rocket will release a cloud of vapor. According to NASA, the clouds will become ionized after their release, which will result in them becoming visible.
Immediately after release of the vapor, the spherical clouds are a mixture of green and violet, but that phase only lasts about 30 seconds when the un-ionized component of the cloud has diffused away.Kevin Koehler, NASA’s Wallops Flight Facility, Virginia
NASA does note in their release, that this will not be as vibrant as previous launches and will be more difficult to see. Partially due to the fact that this launch will be occurring near sunset, and the human eye struggles to perceive the color violet when there’s less light.
