Atlantis' booster requires troubleshooting

By Chris Bergin, 2/13/2007 10:26:10 AM

United Space Alliance (USA) engineers are working on a troubleshooting plan,
following 'erratic' chamber pressure readings on the right hand SRB (Solid
Rocket Booster).
The issue - which was noted last night without specifics - is still expected
to delay rollout by 24 hours, although engineers are looking at possibly
continuing their evaluations on the launch pad. However, two of the IPRs (In
Process Reviews) are officially classed as constraints to rollout.

Well I've read that page, and I'm not much wiser. there is so much text
mixed up on that page that reads in with the text that its a bit like those
spams with embedded  rubbish you sometimes get.

So what is it, the nozzle moving or what?

I hope they are 100 percent happy that there is no leak in a booster. I mean
look what happened last time there was a leak...

The problem is a faulty pressure sensor... one of three in each SRB.
The other two show 'normal'. It is being likened to the ECO fiasco.

I think the plan is to replace all six, just to be safe.
