NASA's rocket launch could light up sky on Saturday

NASA says residents in some parts of the U.S. could be entertained with a sweet treat on Saturday with a light show in the sky.

According to NASA, the lights will be seen by people in the eastern United States and Bermuda, all thanks to a launch of a suborbital sounding rocket, which is being launched from NASA’s Wallops Flight Facility in Virginia.

The agency said the launch is scheduled for 8 p.m. ET with a 40-minute launch window.

The mission will consist of the release of barium vapor, which is not harmful to the environment or public health, that will form two green-violet clouds that may be visible for about 30 seconds.

The agency said the spherical clouds, which are a mixture of green and violet, will appear immediately after the vapor release.

They'll appear for about 30 seconds.

They will then take on a violet color after exposure to sunlight.
