Why use the phrase "grounded"? It's not like they are planning more launches while Discovery is up there! It would be far better from a p.r. perspective to say that they are concerned about this, and that their only priority now is to return the crew safely home, and then once it is on the ground, THEN AND ONLY THEN do you announce you are "grounding" the fleet. Sheesh!
The families of those astronauts must feel unbelievably freaked out right now.
What are you talking about...Atlantis is in the assembly building...
IMHO, this means that if they decide to keep the Columbia docked to the Space Station, rescue using Atlantis or Endeavor IS NOT AN OPTION.
Atlantis was scheduled for lift-off September 9.
