I'm not sure where to write this as I have just started adding articles to Wikipedia. I'm a JPL engineer that has delivered hardware and is now working ATLO on the DAWN spacecraft. I'd like to add comment to the page but would like to channel the info through the main person running the page. One change is... Technically ,L3 Communications Electron Technologies Inc. (L-3 ETI) (formerly a devision of Boeing) of Torrence CA built the ion thrusters. JPL provides the integration and control of the Ion Propulsion System (IPS) which includes the Thruster Gimbal Assembly (TGA)(this is what I delivered), DCIU, PPU, XFS, and the Ion Thruster. Also, is there a page that shows the phase breakdown of NASA missions and can this article publish the cost profile (and any other info) per phase? I'd like to help, let me know. -gg3369 3 August 2006
- There isn't any "main person running the page", in fact there's an official policy against that sort of thing (Wikipedia:Ownership of articles). If you have an idea for a way to improve the article then by all means just dive right in and make the change. The stuff you mention above looks interesting, though I have insufficient background knowledge to feel comfortable adding it myself. I would suggest, though, that you might want to include some sort of external reference to allow the information you add to be verified by third parties. Doesn't have to be something as rigorous as a journal article, just something to reassure people the information isn't coming out of thin air. Bryan 07:01, 4 August 2006 (UTC)
I'm really curious to know how ceres might look like. I dindt knew this project (but so many years to reach it...) PPl plz upload images to commons. It is better for all of us. -Pedro 20:00, 26 August 2005 (UTC)
- There are some very, very low-grade images of Ceres currently existing; however, they're good enough that some features can be identified. Image:1 ceres.png. Shimgray 20:21, 26 August 2005 (UTC)
- thx ppl. I don't like that pic of Ceres. LOL. But at least is something! In the italian wiki there is a nice artwork on it:1 Ceres. But as we know this maybe different from what's out there. -Pedro 00:06, 29 August 2005 (UTC)

[edit] Postponement
At IAF in Fukuoka last week it was announced that Dawn will be postponed by six to nine months, probably launched early 2007, with no impact on the overall schedule thanks to ion propulsion.Hektor 11:03, 23 October 2005 (UTC)
- Getting worse, there are now cancellation rumors circulating at NASA.12.163.163.195 00:19, 4 November 2005 (UTC)

- Seems to take this direction [3]
- No more rumors, it's over. :( [4] i 7 s 03:51, 3 March 2006 (UTC)
- Oh no it's not! :-) [5] smyles 19:57, 27 March 2006 (UTC)
[edit] Images
I've dropped the one fair-use image, as part of our program of clearing out nonfree images. I notice the Dawn website has some photos of the real craft that would make nice substitutes (already on commons perhaps?) Stan 14:38, 9 December 2005 (UTC)
- Plz upload pics to commons. :\ It is a very nice pic!!! :) --Pedro 21:31, 9 December 2005 (UTC)
[edit] Dawn is back
Source: NASA news release. It should be public domain as a U.S. gov't work, so I'll post it here, and we can work the information into the article. Jonathunder 22:59, 27 March 2006 (UTC)
NASA senior management announced a decision Monday to reinstate the Dawn mission, a robotic exploration of two major asteroids. Dawn had been canceled because of technical problems and cost overruns.
The mission, named because it was designed to study objects dating from the dawn of the solar system, would travel to Vesta and Ceres, two of the largest asteroids orbiting the sun between Mars and Jupiter. Dawn will use an electric ion propulsion system and orbit multiple objects.
The mission originally was approved in December 2001 and was set for launch in June 2006. Technical problems and other difficulties delayed the projected launch date to July 2007 and pushed the cost from its original estimate of $373 million to $446 million. The decision to cancel Dawn was made March 2, 2006, after about $257 million already had been spent. An additional expenditure of about $14 million would have been required to terminate the project.
The reinstatement resulted from a review process that is part of new management procedures established by NASA Administrator Michael Griffin. The process is intended to help ensure open debate and thorough evaluation of major decisions regarding space exploration and agency operations.
"We revisited a number of technical and financial challenges and the work being done to address them," said NASA Associate Administrator Rex Geveden, who chaired the review panel. "Our review determined the project team has made substantive progress on many of this mission's technical issues, and, in the end, we have confidence the mission will succeed."
[edit] Definition of Planet debate...
So.. what do you wanna bet that if Ceres is actually re-declared a planet, Dawn won't have to worry about getting cancelled again? :P --Patteroast 15:45, 16 August 2006 (UTC)
[edit] Cracking up
Sorry, but this toggling of the launch date between 20 and 21 June that occurs every couple of weeks in the article is cracking me up. I just had to mention it ;-) Returning to lurk mode. Deuar 22:08, 10 September 2006 (UTC)
- If you find that sort of thing amusing, check out Wikipedia:Lamest edit wars. I doubt in this case it's actually a war, I bet there's just two prominent sources out there that disagree and new people keep coming along and thoughtlessly "fixing" the "mistake" back and forth, but the effect is similar. :) Bryan 23:35, 10 September 2006 (UTC)
