Just 'cause I said I would...
Hopefully, though, this whole episode has made its point -- NASA isn't afraid to tell overbudget missions to stand down. I just *really* wish we could get the magnetometer back on the beastie, though... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

I just *really* wish we could get the magnetometer back on the beastie, though... -the other Doug ah you beat me to this, My title was "DAWN reborn" a new thread was overdue sadly its too late for the magnetometer for technical reasons on the budget, many other recent missions, including our beloved rovers, NH, DI, MESSENGER,etc, have been far more overbudget. DAWN has been much closer to the target and the stand down added to the overrun fortuneately due to the use of ion propulsion, there is a wide launch window extending to at least Oct 2007 and there is no delay in arrival to Ceres and Vesta. |

on the budget, AFAIK NH was on budget - the others were not.many other recent missions, including our beloved rovers, NH, DI, MESSENGER,etc, have been far more overbudget. DAWN has been much closer to the target and the stand down added to the overrun fortuneately due to the use of ion propulsion, there is a wide launch window extending to at least Oct 2007 and there is no delay in arrival to Ceres and Vesta. Hopefully this near-cancellation will serve as a clear warning to future Discovery proposers. Otherwise the way to get a mission flown is going to be to purposefully underestimate costs, include lots of instruments when proposing a mission and once it's approved and spacecraft construction has started a few instruments can be dropped and NASA informed that "oops, we need more $$". If this happens the reinstatement of Dawn is actually bad news. So overall I guess I'm happy that Dawn has been reinstated - but happy with some reservations. |
