What are you talking about?

Post #137,286 by admin 1/23/04 8:31:32 AM Reply	What are you talking about? They don't KNOW what the real problem is, so how can you expect them to give a detailed explanation? The aren't getting any telemetry. There's no way to diagnose on anything other than a gross level. Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."

Evidence? 4. Is something unknown busted? Lack of evidence? These NASA reports are famously empty of content, across the board. Everything out of their press agent's mouth is spun into the best possible form, as if planets and spacecraft were running for re-election. -drl

I hope they considered that, NPR was not too clear) -- Select [link\|http://www.glumbert.com/pictures/Default.asp?index=30\|here].

Post #137,321 by deSitter 1/23/04 10:28:56 AM Reply	Re: They've given us those. Why not just assume bad software and upload a new start? If that doens't work it's dead anyway. I was listening to one of the team leaders describe his local tests involving an impossible scenario. He was testing an impossible scenario, just in case it magically became possible on Mars. Another example I linked involved shock testing a flight instrument when the test would prove nothing other than, yes, you can break this instrument if you shock it. I just get the feeling again and again that NASA has some of the sharpest balloons in the world. -drl

On the other hand, if they can get telemetry first before rebooting (which they can always do as a last resort), they can do some actual debugging instead of acting like NT admins. Now that Spirit has responded with 20 minutes of data, I'd say that the NASA guys are right on with what they're trying to do. Your solution is a last resort only.

Post #137,382 by deSitter 1/23/04 7:08:04 PM Reply	New info It's spontaneously attempting to reboot again and again. There is only one OS I know of that does this - NT. I would not be surprised if this fucker is running some version of embedded NT. I did find out it has a VME bus - perhaps our embedded engineer (Scott2? ChrisR? Burns?) could tell us something. -drl

I notice that Windows is an allowed development platform. Maybe this thing is klezzed.
