Governance Lessons
Lessons from the investigations covering NASA, each attributed to its source investigation.
-
Verify the Interface, Not Just the Specification
The Software Interface Specification correctly demanded newton-seconds; the delivered file used pound-force seconds, and no process checked compliance. A specification without verification is decoration.

Anomalies Are Data — Staff Someone to Chase Them
Trajectory discrepancies and unexpectedly frequent thruster firings were observed for months. With effectively one navigator across three missions, nobody had the capacity to reconcile them. Anomalies that go uninvestigated become root causes.

A Contingency You Never Rehearse Is a Fiction
TCM-5 could have raised the spacecraft to a survivable altitude, but it was never analysed, tested or given commit criteria — so it could not be used. Backup plans require preparation and pre-agreed triggers, or they do not exist.

Handovers Are Where Systems Die
MCO was the first JPL mission handed from its development team to a multi-mission operations team, and almost nobody moved with it. Knowledge of the spacecraft's quirks stayed behind. Staff handovers with people, not documents alone.

Never Cut Assurance to Fund Ambition
'Faster, better, cheaper' traded verification depth for mission frequency. Cost pressure is legitimate — but savings must come from scope, not from the processes whose entire job is catching human error.

Errors Are Normal; Catching Them Is the System
The Board's philosophy: people make errors, so projects need layered processes to catch them. Blaming the units mistake misses the point — eight contributing causes, all organisational, let one error reach Mars.

Put the Right People in the Review Room
Operations navigation staff attended neither the preliminary nor critical design reviews. Reviews conducted without the people who will operate the system cannot surface operational risk.
