NASA announced that it's postponed its Saturday rocket launch at NASA’s Wallops Flight Facility in Virginia to Sunday.
The reason behind the postponement was "due to upper-level winds not being within the required limits for a safe launch."
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, a mixture of green and violet, will appear immediately after the vapor release.
They'll appear for about 30 seconds and then take on a violet color after exposure to sunlight.
