I'm watching before I gotta go to PT lol.
-
4 minutes
-
No launch today, weather :cry
-
delayed til 14:50GMT.
note: even NASA uses GMT...
-
Why can't they send an unmanned, disposable rocket up through some clouds? Ugh, ya'll just ruined my whole day.
-
Damn you rain cloud!

This test flight contains over 700 sensors to measure various stresses the rocket goes through at launch. They are being careful to treat it just like a manned launch, so they get accurate measurements.

You're right, that cloud sure would mess up those 700 sensors :)
Seriously, you really are right. I'm sure they want video of the thing blowing up.

150 foot parachutes... 1 ton each wow

There are lot of scary things about that big pogo stick. The motor itself sets up hazardous vibrations as it approaches burnout, so they're having to install huge shock absorbers and mass dampers to avoid killing or incapacitating the crew on the way up. Yea they might theoretically save some money by re-using components from the shuttle, but they're adding complexity and losing weight/mass margin with all the kludges being put in place to make it work.
Maybe it'll work but I wouldn't put any money on it. We have better systems already integrated that would be lower risk overall.

LOL!
Don't shoot the messenger eagl. I would rather NASA err to caution than not. They have paid a very high price for not doing so, in the past.
Ares is a risky proposition. The last thing they need is to have it explode during a bad weather launch. The press would kill them.
-
You think the press will be any kinder if (when) it blows up on a clear day? We don't have the budget for an extensive flight test program, so every test has to go perfectly or it will risk the schedule to man-rate the system. Any failures and they'll start to talk about how there aren't many test flights scheduled and how there may not even be an unmanned test flight of the full-up integrated system. It all has to work perfectly the first time.

Has there ever been any loss to weather?
-
Challenger was a loss due to weather...O-rings on the SRB's shrunk.

Weather you say? Not according to official investigation. Cause / factor.
-
That big rocket even caught my missus eyes. Wonder why... she has never tanken an interest in space before :headscratch:

My father works for a company that makes the O-Rings in question. N.A.S.A cheaped out for a while and used a different vendor.
After Challenger, they came back to my father's company :noid
-
Going to try again this morning, looks like @ 30 min from now.

IIRC, NASA was advised against launching in low temperatures (by either the o ring mfg. or company that made boosters, i forget) and they went ahead anyway.
-
It was by the O-ring company.
They knew they made a lesser grade O-ring than GreenTweede did :D
-
8 min till launch :rock
-
3 min till launch :banana:
-
It didn't blow up. I feel cheated somehow.
-
Awesome!

The grade of the O-ring was never in question, the operation limits for the O-ring were exceeded.
Also, engineers at the manufacture of the booster initially called for a scrub due to weather. They were overridden by management at Morton Thiokol and non-engineering personell made the final call. I have read the crash investigation reports for both Shuttle diasters. They had multiple issues capable of bringing the space craft down in a variety of ways.
The booster was just the first one to fail,and many years later the foam, ironically both were well known issues before the diasters......

Ahh, then the poor working stiffs were misinformed (but still relieved) that it wasn't their fault.

Yes...
Which sounds better?
"Ares rocket explodes due to NASAs neglegence"
Or.
"Experimental Ares Rocket explodes"
The press is an eating machine, it'll dig and dig and dig, you just gotta keep feeding it little crumbs to keep it satisfied. If you don't, they'll screw you over. The press isn't into reporting "the truth", rather ratings and money, and unfortunatly, bad news sells. I've been on the recieving end of the media, it isn't pretty.
