NASA rockets leave glowing trails against the night sky
Five sounding rockets released 80 seconds apart Tuesday morning left glowing trails in the night sky as they traveled through the upper-level jet stream.Posted — Updated
The rockets released a harmless chemical which, when combined with the oxygen in the atmosphere, created glowing clouds. Cameras positioned at the Virginia launch site along with others in Duck, N.C., and near Atlantic City, N.J., tracked the clouds. Imagery from those cameras will be used to create a three dimensional model of the winds, which can reach 300 mph, for further study.
The launch, originally scheduled for March 14, was scrubbed several times due to weather. Mission requirements included clear weather not just at the launch site but also at the other two camera sites. This morning's launch came just minutes before the end of the launch window due to high surface winds at the launch site.
