Stafford-Covey Group Finding Probably Won't Cause Launch
Delay
Just three weeks before the space shuttles' Return to Flight, a
NASA advisory group says the space agency has failed to address
three critical safety issues: eliminating critical launch debris,

boundaries unlike any seen previously on Titan.
