I watched the launch Saturday night. It took half a minute to clear the launch pad. Great night launch. HT Florida Today.
Weighing 5,200 pounds, the DSP-23 satellite completed a 6 hour, 20 minute mission and was deployed into its proper orbit at 3:10 a.m., today. The DSP-23 launch completes the deployment of this important constellation of satellites. DSP satellites provide early warning for intercontinental ballistic missile launches and have been used by the military for more than 30 years.
