W8JI made a gross error in his measurement and then tried to rationalize the impossible result. Cecil: How would you have like to be working at NASA, with this group; And, you were the one responsible for not coverting kilometers to miles and SMACKING that spacecraft we lost into Mars? ;-) It wasn't km and miles, it was pounds and newtons AND the error was that Lockheed Martin supplied the thrust data in pounds, unlike the contractual requirement to supply it in Newtons (which is what we at JPL have used for decades). The error wasn't caught because the absolute magnitude of the force is very small, so the differences from predict to observation were on the order of the measurement uncertainty. (We're talking measuring the velocity to mm/sec and range to mm, when its at Mars.) I'd venture that anyone would find measuring distances to 1 part in 1E12 challenging... Crud, I've volunteered on serving on those soup-lines, would hate to have seen ya' there. chuckle Regards, JS |
