On Tue, 29 Jul 2003 04:13:20 GMT, in a place far, far away,
h (Rand Simberg) made the phosphor on my monitor glow in such a way as to indicate that: Stop trying to attribute all ills of the space program to the fact that people happen to be going as part of the mission, Greg. It's a loser's game, and one that its practioners would (or at least should) have eschewed long ago Doh!

It was bad management, of course. (Although to be fair, Mars is a particularly unforgiving target.) As I said at the beginning of the other thread: With a good mandate, management may be good or bad. But with a bad mandate, management is invariably bad. Public relations has always been the principal purpose of manned spaceflight, not only in the United States but worldwide. It has not been a good mandate since the 1960s. Even then, it was only good in a perverse context, namely the Cold War. How about the original shape of the Hubble mirror--what did that have to do with the fact that it was launched on an Evil Manned Launch System? It was either bad management or bad luck, although flying on the shuttle was an unwelcome distraction for the mission. -- /\ Greg Kuperberg (UC Davis) / \ \ / Visit the Math ArXiv Front at http://front.math.ucdavis.edu/ \/ * All the math that's fit to e-print * |

The loss of Mars Climate Orbiter was 99% bad management -- the units error would have been caught and corrected in a well-run project, because there were plenty of hints that something was wrong. Mars Polar Lander was much more of a routine engineering screwup, but one can still reasonably argue that poor management was at least a major contributing factor. The Deep Space Two micropenetrators that were lost with MPL were simply not ready to fly, but management decided to fly them anyway. Several of Galileo's problems can be traced back to management. (I mean, a star tracker that's only tested in two or three orientations??? Who was running *that*?) Hubble's main mirror was a management screwup through and through. The essentially-total loss of WIRE was not because there hadn't been hints that the pyro circuitry had something wrong with it, but because management didn't insist that those be followed up on. X-33 was a management disaster from beginning to end. X-34 wasn't much better. Mars Observer's loss was mostly an engineering failure, but management over-optimism about "flight proven" subsystems did contribute. -- MOST launched 1015 EDT 30 June, separated 1046, | Henry Spencer first ground-station pass 1651, all nominal! | |

Yes, except that management was compelled to deny those estimates. If not in its words (this time), certainly in its attitude. Likewise NASA management is also compelled to insist that microgravity research is of megaimportance. -- /\ Greg Kuperberg (UC Davis) / \ \ / Visit the Math ArXiv Front at http://front.math.ucdavis.edu/ \/ * All the math that's fit to e-print * |

Where does the nature of the launcher figure into that? |

The Deep Space Two micropenetrators that were lost with MPL were simply
not ready to fly, but management decided to fly them anyway. Is there anything but the grapevine to support that? It did seem a good idea, a rush job, and strange amounts of silence after the fact... Several of Galileo's problems can be traced back to management. (I mean, a star tracker that's only tested in two or three orientations??? Who was running *that*?) Hadn't heard of that one... Hubble's main mirror was a management screwup through and through. Interestingly enough, a BBC program that airead yesterday here in Germany presented it as basically bad luck - that a flake of paint was missing in just the right place on the null corrector for things to go wrong. On the other hand, they kept records and even the original measurement hardware was still in place so that the causes for that screwup could be reasonably determined. Now that is _good_ management! (Please excuse me while I fetch a mop to take up the sarcasm.) Jan |

What makes you think it doesn't? What I meant is that unmanned spaceflight doesn't ALWAYS fall to bad management, not that it doesn't ever. That is clearly true: NASA unmanned spaceflight does great things every year. -- /\ Greg Kuperberg (UC Davis) / \ \ / Visit the Math ArXiv Front at http://front.math.ucdavis.edu/ \/ * All the math that's fit to e-print * |

Actually landing on Mars is harder than merely orbiting Venus or even Jupiter, or than landing on the moon. Your basis for this statement is suspect. And certainly you realize that there have been at least one (marginally) successful landing on Venus, don't you? Furthermore, your original statement didn't qualify itself as limited to landings, just that ". . . Mars is a particularly unforgiving target." And on that point, I'd have to remind you of Vikings 1 and 2 and Mars Pathfinder; landing is difficult on any body from orbital or interplanetary velocities. It is not, however, impossible. Your penchant for broad, unqualified generalizations is partly why the sci.space long-term regulars don't take you very seriously. Although interestingly they discovered a new difficulty of an inner Jovian orbit mission: massive charged particle radiation. -- Herb Schaltegger, Esq.
