Two questions for discussion... 1. How long should we wait before launching another shuttle, if we CANNOT find the cause for the explosion? 2. Should we build another shuttle, or the next generation spacecraft? - Jim Van Zandt

In his news conference, the acting director of NASA stated that if the definite cause isn't found, then a "shotgun fix" will be applied, as has been done in the past, meaning fixing everything that could have caused the problem. That'll be the determining time period. >2. Should we build another shuttle, or the next generation spacecraft? Use the existing ones, but start design on the next generation. Mojo ...

Doesn't look like this will be a problem; there seems to be a new defect uncovered in the shuttle design with each morning's paper. A more serious problem is: 1(a). What do we do if it turns out that the shuttle design is fatally flawed--that we cannot, for any reasonable expenditure, get the chance of catastrophic failure below ~1-2%? > > 2. Should we build another shuttle, or the next generation spacecraft? From a crass political standpoint, the best thing to do would be to rise up in national righteousness and immediately build a replacement while there is still lots of public enthusiasm for carrying on. From the more practical point of view, the three remaining shuttles are sufficient to carry out the real purpose of the program--finding out (the hard way) how one goes about building a good space shuttle. I think we ought to take the latter course, sell shuttle space (for satellites, etc.) for rock bottom with the understanding that there will be delays and risks, and learn all we can with the goal (and commitment) of deploying a real "commercial airliner" quality space shuttle by 1993.
