Space Policy: Why Mars should be our top priority.

Derek Lyons wrote:

But, as I stated above, the real problem isn't critical failures. The
real problem is the accumulation of non critical failures steadily
reducing performance while increasing headaches.


In a lot of the Mars flight scenarios you see two or more identical
spacecraft sent on the mission, so that in case one fails, the crew of
the failed ship can transfer to the other one.
This would work fine if it weren't for the problem that both ships might
well have the same fault in their design.

You're just a poser, really. You've never heard of fault tolerance,
failure modes analysis, and fault trees. You just come to the usenet and
say "no can't be done" with this "not invented here" attitude.

I came here to fish for people interested in Mars for my website.

You are not invited.

Laying golden eggs would also be nice. Lots of things 'should' be done

Have you ever had to engineer a major system?

It is what I do for a living...

What a loser.

My point is that system anaylsis and fault trees are not magic wands,

Yeah, yeah yeah. And computers are run by gremlins in the box. You've
never heard of it. Hell, you can't even spell analysis.

This trying to sound smart by saying it can't be done is absurd. You
don't have a clue.

I do engineering for a living. You've obviously never had to engineer
a complex fault-tolerant system.

That's nice. Tell me other things I'm not invited to do, like poke

Apparently not, if you believe what you've been claiming.

Give it up, Derek. He seems to be just another loon, self-obsessed
with his own ideas.

He's not interested in anyone who actually thinks. They're heretics,
you see, questioning his sermonizing from his own personal mount.

Yeah, I'd pretty much decided that last night's exchange would be the
last.

I don't see you to buddies thinking.

At best, your contradictions can be called "mindless gibbering", or
deranged ranting, but thinking....

No.

If what you said about failure modes analysis was meaningless, why say it?

You just GIBBER to see yourselves on the internet. You produce verbal
fecal matter, and then you wonder why people think you're stupid.
