systemic problems at nasa



Systemic Problems at NASA

In a recent blog entry on NASA, I said the following,

We see the government overriding good decisions already made, in

the name of junk science, and over a long period of time. Who, with

any sense of pride or integrity, could bear to work in such an

institutional climate? Who will be left after the predictable brain

drain? And anyone familiar with the bowels of a bureaucracy will,

rest assured, understand what things will be like for any

conscientious newcomer. Think about all this for a moment.

..

For the engineers working at NASA, their choice really is to

continue working there at the risk of their self-respect and mental

health or to get the hell out.

It appears that my speculation on the "corporate culture" of NASA was

right on the money. All bold is my own.

The final report, however, includes supplemental papers, including

one signed by seven members that cites continuing management

problems, engineering shortfalls and schedule pressures in the

shuttle program.

For example, the members wrote that NASA did not plan its return to

shuttle flight by determining what work needed to be done and

setting a realistic schedule. As a result, engineers redesigned the

shuttle's external fuel tank before knowing how vulnerable the

ship's heat shield was to debris impact.

A piece of insulation fell off Columbia's tank during launch and

damaged the ship's wing. The shuttle was torn apart by atmospheric

forces 16 days later as it re-entered the Earth's atmosphere for

landing.

The report also said NASA is too willing to accept risks based on

past performance, an attitude that doomed the Columbia crew.

[Felipe Sediles blogged specifically about this point. -- ed]

Because it had never lost a crew due to debris falling off the tank

and striking the shuttle, NASA considered the issue a matter of

post-flight maintenance, not flight safety.

The members reserved their harshest criticism for NASA management.

"What we observed, during the return-to-flight effort, was that

NASA leadership often did not set the proper tone, establish

achievable expectations, or hold people accountable for meeting

them," the report said.

"On many occasions, we observed weak understanding of basic program

management and systems engineering principles, an abandonment of

traditional processes, and a lack of rigor in execution."

But this is nothing. It's a coin-toss as to which of the following is

more damning:

(1) In another supplemental report, panel member Charles Daniel, a

former NASA engineer, pointed out that NASA never did establish

exactly why the chunk of foam fell off from Columbia's tank.

Instead, the foam in the area was removed and replaced with

electric heaters to ward off potentially dangerous ice formations.

[This is aside from the fact that an inferior type of foam had been

used. NASA does know that little detail. -- ed]

(2) The report was written before NASA launched shuttle Discovery

last month on the agency's first manned mission since the Columbia

accident. Several large chunks of foam fell off during that launch

as well, prompting NASA to halt shuttle flights again until the

problem is fixed.

We launched the shuttle not knowing -- aside from the fact we were

using inferior foam -- why the foam came off? And knowing the contents

of this report?

Keep this in mind the next time you hear someone damn the profit

motive for giving incentives to "cut corners" or "ignore safety".

Suppose you're an astronaut. Would you rather have bureaucrats in

charge of the design of your ship, bureaucrats who will be able to

hide behind their mammoth organization and a report (a big pile of

paper) if something goes wrong? Or would you rather have some greedy

bastard (This expression suddenly sounds fit for family hour now.)

running things who would lose his ass if something bad happens?

I'll go with the greedy bastard.
