Bad weather has prompted NASA to reschedule the launch of five rockets from its Wallops Facility in Virginia.
The rockers are part of a study of the upper-level jet stream.
The launch had been set for Wednesday morning but has now been pushed back to early Thursday. Bad weather has postponed the launch several days.
The Anomalous Transport Rocket Experiment (ATREX) will help scientists understand the process behind the jet stream located 60 to 65 miles above Earth's surface.
The rockets will release a chemical tracer that will form white clouds that allow scientists and the public to visualize the winds in space. Residents from South Carolina to southern New Hampshire and Vermont might be able to see the clouds for up to 20 minutes.
