We’re lighting up the night! We’re going to release blue-green and red vapor to form artificial clouds to allow scientists to visually track particle motions in space. The clouds may be visible along the mid-Atlantic coastline from New York to North Carolina, but the vapors are not harmful to people, animals or the environment. Join us tonight between 9:04 and 9:19 p.m. EDT. Learn more: http://go.nasa.gov/2sVKTeE
