According to NASA, the amount of damage to thermal tiles noted on Discovery was significantly lower after the latest mission. According to the report, there was a 33% reduction in the number of dings on the belly of the orbiter and an almost 50% reduction in the number of hits greater than one inch. This would seem to indicate that the new foam is working better. "The vehicle looked very good," Thomas Ford, a member of NASA's ice-debris inspection team at Kennedy Space Center, said Wednesday. "It's definitely gratifying."
