RELEASE : 18-06
ST5 Launch Postponed 24 Hours Due to Weather Forecast
The launch of NASA's ST5 spacecraft aboard an Orbital Sciences Pegasus XL rocket has been postponed 24 hours to Wednesday, March 15, due to predicted launch weather conditions.

Due to an approaching weather system, there is an 80 percent probability of not meeting the launch weather criteria within the area of the drop box, the location over the Pacific Ocean where the Pegasus rocket will be dropped from the Orbital Sciences L-1011 aircraft. The forecast conditions improve on Wednesday with only a 20 percent chance of not having acceptable weather.

On Wednesday, March 15, launch is targeted for 6:02 a.m. PST. Launch coverage on NASA Television will begin at 4:30 a.m. PST.
