The Independent Oversight Board will guide the joint SS/L-Sea
Launch investigation team, which has been working together for
several weeks to collect and analyze data with the objective of
determining the root cause of damage to one solar array on an
SS/L 1300 satellite that was launched on
Instrument data showed an unexpected, isolated event around 72 seconds after liftoff, which registered on sensors on the rocket. Following the launch, SS/L and Sea Launch each conducted independent investigations to examine and analyze spacecraft and launch vehicle build records, ground test data and flight telemetry data, including readings from accelerometers, pressure sensors, and microphones in the payload compartment. Those analyses identified no shortcomings in the build quality or ground testing, but so far have not identified the root cause of the anomaly.

The Independent Oversight Board and the joint SS/L-Sea Launch team will continue to work together over the coming weeks to consolidate the results of their independent investigations and to identify additional analyses and tests to be performed. With the Independent Oversight Board driving the effort, the goal will be to identify the root cause of the anomaly within three months' time.
