That was offset by other issues, including taking everything out of Enterprise that could be used and re-installing it in the STA. Brian |

As if the name of a vehicle truly makes any difference in public interest in what NASA is doing. The fact is that the shuttle program was dull, dull, dull to most Americans. Yes they knew it was flying missions, but it appeared routine since all they ever did was go round and round the earth in LEO. ISS is much the same. Sure people know there are astronauts on ISS, but most have no clue what they're even doing there.
