Shuttle Launch Delayed Again, Possibly Until December
An anonymous reader writes "NASA engineers worked overnight trying to fix the electrical problem that forced the launch of space shuttle Discovery to be delayed again. Mission managers will meet later Wednesday to figure out if a launch on Thursday is even possible. The tentative plan is to have Discovery lift off Thursday at 3:29pm. If that does not happen it would be rescheduled for Sunday. If it cannot launch Sunday then it will have to wait until December. NASA engineers have a lot of work on their hands Wednesday morning. Discovery has an electrical issue that forced officials to postpone its liftoff, which had been rescheduled for Wednesday afternoon."
Did they check if it's plugged in?
Have they tried turning it off and on?
The shuttle was an misconceived expensive piece of junk designed to make the Russians go broke copying it. (Read Buran). We should have never given up on the Saturn V as out heavy lift platform.
Why not just move the remaining Shuttles to museums like the Smithonian and Wright/Pat and display them as the costly mistakes they are.
We also could build a modern Saturn V with better metallurgy, and computers very easily. I think the reason we don't is that the design is public domain and the usual contractors can't charge 10 times what it is worth.
So there!

Didn't they promise us 50 launches a year with this thing? What ever became of that?

Whoever tagged this "cowardly", I'd like to see you shoot into space when conditions aren't optimal, where conditions not being optimal can mean a horrible death by being vaporized.
This article contains some more specifics regarding the problem. Apparently one of the main engine controller computers (the computers that regulate main engine gimbaling and throttle control) failed to power up properly. There was a short time period where a low-voltage occurred which flagged a boot-up sequence issue. Engineers are trying to figure out what caused the voltage drop and, thus, triggered the error in the processor initialization. More information regarding the SSME controllers can be found here.
Apparently the breaker that controls the processor was cycled five times over night. Engineers are guessing that the cycling caused some funny transient anomalies in the circuit which caused the fault. Despite the fault, the main events controller for the shuttle system was brought to full power and is operating nominally, so it's not like the whole computer is crap. NASA just wants to be sure that, a) the fault was actually caused by the breaker cycling and b) the fault won't cause further glitches in any of the other controller systems on the shuttle.
Interesting stuff indeed. It's probably a good thing that NASA is demanding certainty from it's engineers before clearing Discovery for launch.

Great post!

So your comment is out of order.
Boeing, Arianespace and various other companies launch things into orbit on a regular basis. Putting a capsule on top is easy, finding people willing to pay for it is the hard part.
That depends on what you're trying to get into orbit:

Holy shit man, what's with the summaries lately?? Redundancy all around, everywhere.
Not sure if it made it to Slashdot or not, but the Constellation program (which was prohibitively expensive) has been scrapped in favour of a more affordable SDLV similar to DIRECT's Jupiter.

... ISTR that each time there has been a shuttle disaster, it was during winter.
These fuckin things are old and rickety, and I don't think they should be permitted to launch when ambient overnight temperatures are lower than, say, 45 degrees. Not hard most of the year in south Florida.
you can't fight your own battles? you wish to deny others their opinion?
why do you cower? what are you afraid of?
the truth threatens you. you're completely pathetic.
Pathetic is when you need all those sockpuppet accounts because you can't just maintain a single account in good standing. you are NOTHING. bitch. A single account with a single karma rating threatens you. You're completely pathetic. Keep running away from the down-mods you soundly earn, you coward fuck.
I'd ask you what you are afraid of but we already know. You are afraid of being judged on the merits of what you post. That is why you have to keep creating new accounts.
NASA should just buy truckloads of Viagra. It will help them get it up.
The shuttle is getting to old and stuff like this just gets harder and harder to fix.

Last I checked they are putting payloads into orbit, not humans. And what is the success rate with these less complex payloads?

I made this mistake with him too, just let the mods keep killing his accounts and him keep wasting his life creating new ones.
If you feel you must do something register a bunch of names in the form he would use to kill them off.
Scrap it now and put it out of its misery, its already put the space program back 30 years

So the universe doesn't allow this to happen because it's a paradox and that would mean the end of the wo
Oh, the Shuttle Launch is delayed... Sorry, wrong thread.
