DSP F19

NSSDCA/COSPAR ID: 1999-017A

Description

DSP F19 was a USAF Defense Support Program missile early warning satellite equipped with an infrared telescope to detect rocket launches. The Titan 4B rocket placed the IUS upper stages and payload into a 188 km x 718 km x 28.6 degree parking orbit. The first stage on the IUS burned at 18:14 GMT and put the second stage and payload into a geosynchronous transfer orbit. The IUS second stage fired at 23:34 GMT. However, the two stages of the IUS failed to separate completely. At least one connector remained attached. This meant the second stage motor nozzle did not extend properly. When the stage fired, the vehicle tumbled during the burn and the satellite was left out of control in a useless orbit.
