Yes it's happening after all these years, the mission to the last planet!
And maybe to celebrate the confirmation of budget, NASA approval preparations and the fueling of the RTG (radioisotope thermoelectric generator), there is an updated web site at http://pluto.jhuapl.edu/ Launch will be January 2006 with arrival at the Pluto Charon system July 2015 (mark your calender!) and then on through the Kuiper belt during 2016-2020 and beyond. 20.8-centimeter telescope for 100m resolution at closest approach IR/UV spectrometers 2 x 8GB data recorders data rate: 768 bps (sic) to 70m DSN 465kg including fuel $650m 336 days to launch -------------------- |

QUOTE (DEChengst @ Feb 19 2005, 09:15 PM) QUOTE (Alan Stern @ Feb 19 2005, 09:09 PM) The RTG and the necessary fuel are both in good shape. Previous problems resolved. All needed fuel is now ready. We expect 190 W or a tad more at Pluto in mid-2015. The s/c requires ~165W, so there is a healthy margin. Why does bad news always make big headlines and the good news somehow just doesn't get mentioned ? They scare the hell out off you by telling telling New Horizons may fly late or not at all due to lack of plutonium, but once the problems are solved the press somehow keeps silent. Thanks for the update and making me sleep a little bit better tonight The shortage of plutonium was caused by an alleged security problem at one of the labs. A couple of CDs with classified information on them went missing and everything stopped while they reviewed security protocols etc. I read recently that the CDs that were susposedly missing never existed and all the fuss was over an inventory problem. |
