Crisis averted…New Horizons back on track

NASA’s New Horizons Plans July 7 Return to Normal Science Operations.

The investigation into the anomaly that caused New Horizons to enter “safe mode” on July 4 has concluded that no hardware or software fault occurred on the spacecraft. The underlying cause of the incident was a hard-to-detect timing flaw in the spacecraft command sequence that occurred during an operation to prepare for the close flyby. No similar operations are planned for the remainder of the Pluto encounter.

Yet another example of how Verification and Validation in the lab simply cannot replicate the operational environment. Quirky things always seem to occur during operations that are never seen in the lab or during system testing.
