But they aren't going to launch even if just one of them gives a strange reading. If they lose one, that means they only have one backup. They are not going to take the risk. In the previously scheduled launch, they could have even lost a second one and still launched but they didn't. NASA knows what they are doing with safety and they aren't going to take any chances just to get it up in the air. Everyone wants to see it go up, but no one wants to see it go up and fail, or go up and not return home.

That is not entirely true, according to this if the sensor fails again they will try to draw up an exception for the rule and fly with 3 out of the 4. Current rule is 4 for 4

Re: NASA's Return to Flight Mission July 13!
 

The problem with the LH2 ECO (engine cutoff) sensors appears to be a grounding or EMI (Electromecchanical interference) in the wiring harness.
The attached URL shows several good illustrations of the sensors and their locations. The latest information that I have is that the flight might occur as early a Tuesday.

well this stinks im gonna be in vero beach on tuesday. won't be able to see the launch as well as from my back yard. oh well. I hope the launch happens though. it's detrimental not only to the space program but to the economy in my area as well.

Re: NASA's Return to Flight Mission July 13!
 

They are expecting to launch tomorrow!
I hope everything goes well and they can get everything done that thay plan on doing!

Re: NASA's Return to Flight Mission July 13!
 

I'm going to be making sure I get up in time for the launch (and not accidentally sleep till noon like I did this morning :p ). From what I understand, they are "Bending the rules" and may fly even if the issue pops up again, but hopefully it wont.

Re: NASA's Return to Flight Mission July 13!
 

So, I had the date of the original launch off, unfortunately I did not get so lucky with take two. Hoepfully everything goes well though and I can watch it again after work.

Re: NASA's Return to Flight Mission July 13!
 

the countdown is going i cant wait, I will take pictures from were i am located. I am about 25 miles from launch site

Re: NASA's Return to Flight Mission July 13!
 

The launch is being broadcast on CNN, MSNBC, NBC, and also on Yahoo News here:

With a minute or so delay from the TV stations:

14 minutes remaining.

Re: NASA's Return to Flight Mission July 13!
 

Well, according to CNN, on the last fuel sensor test, they all worked. Hopefully it stays that way.

Re: NASA's Return to Flight Mission July 13!
 

And we have liftoff!!! Woo Hoo :cool: :cool:

Re: NASA's Return to Flight Mission July 13!
 

main booster detached and they are in orbit!

Alright, how are they gonna get it down?

Re: NASA's Return to Flight Mission July 13!
 

Usually gravity takes care of most of that. Anyway, we'll see how the next few days go with inspections. :)

Re: NASA's Return to Flight Mission July 13!
 

What happens to the rockets after they detach? How does NASA make sure they dont land on something that they weren't supposed to land on?

Re: NASA's Return to Flight Mission July 13!
 

The Solid Rocket Boosters land about 140 miles downrange in the ocean after they detach at ~40 miles in height. They are recovered and resued.

The external tank detaches even higher and breaks up on the way down.
