The eleventh time was a charm at Wallops Flight Facility.
At 4:25 this morning NASA launched its sounding rocket that will release vapor into the upper atmosphere to study the motion of particles in space.
The red and blue-and-green clouds could be visible along the mid-Atlantic coast from New York to North Carolina.
They are expected to reach more than a hundred miles in space.
The launch had been delayed 10 times before because of cloudy weather and rain.
