Atlantis' re-entry has been delayed due to a mysterious object:
I hope its not a piece of something important. Another lost shuttle would likely mean the end of American space flight until NASA can develop a new orbiter.
NASA has been forced to hold off Wednesday's landing of the Shuttle Atlantis because of an object — possibly debris — floating nearby, shortly after sensors in the craft's wings indicated the shuttle had been hit by something.
NASA officials want to make sure it's not a piece of the spacecraft, something that might in some way endanger the crew and ship on re-entry.
No one knows what it is for certain, though some reports allege that the object may have come from the craft's cargo bay. The mysterious, gray round object is orbiting near Atlantis at an altitude of 187 nautical miles.
