“Then fix it.”
“You don’t care about the historical significance?”
“No.”
“You’re disappointing.”
“So I’m told.”
OBSIDIAN-7 remained operational.
The mission plan was revised.
The propulsion anomaly consumed part of its expected service life, but the stabilized valve behaviour held.
Every few months Eleanor sent Isaac a telemetry screenshot.
No explanation.
Just the graph.
Flat harmonic.
Stable pressure.
Green.
Isaac usually replied with one word.
Good.
The audit produced changes beyond people losing positions.
Combined-environment modelling became mandatory earlier in certain review pathways.
Independent engineering concerns could no longer be removed from customer-facing risk packages without documented disposition.
Technical dissent procedures were rewritten.
Not perfectly.
Systems never became perfect.
But harder to ignore.
That mattered to Isaac more than Cameron’s resignation.
One afternoon, an engineer in her first year on the lunar program knocked on Isaac’s office door.
His office surprised people.
Small.
No awards.
No framed mission photographs.
One picture of Robert Merritt standing beside the garage in 1984.
One coffee mug.
A box of mechanical pencils.
The young engineer held a tablet.
“Do you have a minute?”
“Probably.”
She entered.
“I think there’s a problem with the actuator-cycle assumptions.”
Isaac looked up.
“Who else have you told?”
“My lead.”
“What did they say?”
“That the margins are conservative enough.”
“What do you think?”
“I think they’re looking at each loading case separately.”
Isaac sat back.
The sentence entered him like an old sound.
“What do you need?”
“I want somebody to check my model before I push it again.”
Isaac stood.
“Show me.”
They worked for two hours.
Her concern was partially correct.
Not catastrophic.
Not mission-ending.
But real enough to require a design change.
The lead engineer accepted the result.
Schedule moved six days.
Nobody was fired.
Nobody buried the report.
Nobody summoned legal.
The program simply changed the part.
That evening Isaac called Eleanor.
“You knew.”
“Knew what?”
“You assigned her to my group.”
“I assign many engineers.”
“She’s stubborn.”
“Coincidence.”
“She notices coupling effects.”
“Lucky.”
“She reminds you of me.”
Eleanor laughed.
“Isaac, nobody reminds me of you. I make active efforts to prevent that.”
He ended the call.
But he was smiling.
Years later, people would tell OBSIDIAN-7 as a story about genius.
They would say a forgotten engineer working in a small Texas garage solved a problem the biggest aerospace minds in the country could not.
Isaac disliked that version.
It misunderstood everything.
The NASA engineers were not fools.
Adrian was brilliant.
Grace was brilliant.
Eleanor was one of the best systems leaders Isaac had ever met.
The failure happened not because nobody was smart enough.
It happened because the organization had separated a system into departments and then convinced itself the divisions on an org chart existed in physics.
Thermal engineers studied heat.
Structural engineers studied vibration.
Propulsion engineers studied pressure.
Managers studied schedule.
Lawyers studied exposure.
Everyone did their job.
The vehicle experienced all of it at once.
