If you live along the Eastern Seaboard and wake up early Sunday, you could be treated to a colorful sky hours before sunrise.
Blue-green and red clouds could be visible in the predawn sky from New York to North Carolina, thanks to a NASA rocket due to be launched from Wallops Flight Facility on the eastern shore of Virginia.
NASA had hoped to launch the rocket early Saturday, but had to scrub the attempt because of boats in the area where the payload is expected to fall back to Earth.
The Terrier-Improved Malemute sounding rocket is now scheduled for launch between 4:26 a.m. and 4:41 a.m. ET. And in this case, the rocket launch isn't even the cool part.
Four to five minutes after launch, the rocket is expected to deploy 10 canisters about the size of soft drink cans, each containing a colored vapor that forms artificial, luminescent clouds.
The clouds, or vapor tracers, are formed "through the interaction of barium, strontium, and cupric-oxide," according to NASA.
