That article is a mess. It needs serious clean-up. Themanwithoutapast 11:52, 5 August 2006 (UTC)[reply]

Resolution

[edit]

The resoltion isn't cited but just a reality check on a resolution of 160m, thats saying an object would need to be roughly the size of Guam to be picked out from another object, this seems like a poor tool to use for "Drawing "pictures" of the Moon and obtaining three-dimensional images of the lunar surface" Especially considering a much more powerful tool to do this is certinly not a technological problem, just a weight and design porblem. Even including a lens that poor seems useless. Just looking to see if anybody found the original source of the info. —Preceding unsigned comment added by 132.61.176.6 (talk) 06:09, 25 October 2007 (UTC)[reply]

The page http://lunar.gsfc.nasa.gov/library/05_CHANGE_Guiness_Slavney.pdf says the CCD camera resolution is 120m, image interferometer has 200m resolution, microwave radiometer has 30km resolution. Narayanese 21:39, 25 October 2007 (UTC)[reply]
you mean the Guam is only 160m? Perhaps I misunderstand you. 120m is not very good, but it is enough. It's moon, not earth... Hhyy best (talk) 17:08, 27 November 2007 (UTC)[reply]

Footprints on icon

[edit]

On the logo for the program, those grey spots. Do they look like footprints to anyone? Roswell Crash Survivor 03:26, 23 September 2006 (UTC)[reply]

could be, the entire it also look like the word for "moon" in chinese.218.186.9.3 22:57, 13 August 2007 (UTC)[reply]
Yes, if you go to the CLEP site the flash animation clearly shows footsteps morphing into the logo. --Adzze 09:42, 25 October 2007 (UTC)[reply]

Ref for postponement reason?

[edit]

The ref for:

is entirely in Chinese. I clicked on the English link on the page, but it doesn't work. (A) Does anyone have an English link for this, and (B) can we reword this sentence? I'm thinking something more like "Originally scheduled for April 2007, the launch was postponed to allow a better time for sending the satellite to orbit." If we really feel like we need to qualify that reason, then perhaps "Originally scheduled for April 2007, the state media reported the launch was postponed to allow a better time for sending the satellite to orbit."

Inacurate Information

[edit]

Can someone verify the statement "Being Chinese, it is also comprised mostly of lead (1,950 kg) melted down from childrens' toys originally intended to be exported to the United States." This statement doesn't seem reasonable for a myriad reasons and there is no footnote to support it. —Preceding unsigned comment added by 216.36.70.149 (talk) 18:29, 24 October 2007 (UTC)[reply]

It was obvious vandalism that was correctly reverted. Ben Hocking (talk|contribs) 18:36, 24 October 2007 (UTC)[reply]


Some brain damaged kids did it....Deathkenli 07:41, 25 October 2007 (UTC)[reply]

Brain damaged kids can type? They need better poison! 24.89.245.62 14:53, 28 October 2007 (UTC)[reply]

Element listing

[edit]

Article says : "China hopes to expand the number of the useful elements to 14 (potassium (K), thorium (Th), uranium (U), oxygen (O), silicon (Si), magnesium (Mg), aluminum (Al), calcium (Ca), tellurium (Te), titanium (Ti), sodium (Na), manganese (Mn), chromium (Cr), and lanthanum (La)), compared with the 10 elements (K, U, Th, Fe (iron), Ti, O, Si, Al, Mg, and Ca) previously probed..."

By my count, if the chinese discover all the elements in their list the total number, taking into account the first list, will be fifteen - K, Th, U, O, Si, Mg, Al, Ca, Te, Ti, Na, Mn, Cr, La, and Fe. Xt828 01:29, 25 October 2007 (UTC)[reply]

The Chinese document didn't mention Fe, hence the 14. Of course, it also was somewhat ambiguous, as there was an "etc." at the end of the list. I encourage others to read the linked to document and see if they can find better wording for that statement. For those who read Chinese, perhaps they can refer to the original document to clear things up. (Please let us know on the talk page where these documents differ, if they do.) I edited this bit quite heavily, as it initially said the US had only previously probed 5 elements. In looking to make those 5 elements explicit, I discovered the statement was completely wrong.

Lunar Soil?

[edit]

Shouldn't it rather be Lunar Regolith? —Preceding unsigned comment added by 58.2.238.143 (talk) 03:18, 25 October 2007 (UTC)[reply]

who cares? Soil is regolith by another name. It's just dirt and rocks. 204.52.215.107 05:53, 26 October 2007 (UTC)[reply]

How often do we need to update?

[edit]

It just completed its 2nd course correction (or as the Chinese called it --- 'Transfer').

http://www.cctv.com/english/20071026/104373.shtml

So it's on the way to the moon, do you think we should update that in the main article? TheAsianGURU —Preceding comment was added at 06:26, 27 October 2007 (UTC)[reply]

I don't have strong feelings about it, but I'd argue that the article only needs to be updated for significant milestones or unexpected events. IMO, course corrections that come off as planned do not necessitate an article update. Ben Hocking (talk|contribs) 13:23, 27 October 2007 (UTC)[reply]

China says lunar image authentic

[edit]

Anyone know the story on this? "China's space program has defended a photo of the moon's surface taken by its lunar probe as authentic, dismissing critics who suggested it had been copied from a similar image captured by a U.S. orbiter." -- http://news.yahoo.com/s/ap/20071203/ap_on_re_as/china_lunar_skeptics_2 Ewlyahoocom (talk) 19:22, 6 December 2007 (UTC)[reply]

Lunar surface is an ever changing surface with new craters are found everyday.
http://www.planetary.org/blog/article/00001248/
Besides, 2 years is a long time, I don’t think it will be the same for even 2 days.
Also, when you take picture from an orbit, you mix all the pictures that you take from different orbits with different heights to improve pixel. Whoever says it's a fake, I doubt the person has deep understanding of Space Imagery. If the Chinese wanna fake something, they would cheat you on something else. TheAsianGURU (talk) 22:53, 6 December 2007 (UTC)[reply]
I was astonished by these news reports. They discuss a "conspiracy theory" (that the Chinese stole their image because the probe doesn't work), while ignoring the obvious explanation (the Chinese would want to start by testing the quality of their optics against a known location). If the satellite orbits the Moon for months and never images a spot no one photographed before, then I'll start considering conspiracy theories. 70.15.116.59 (talk) 02:21, 7 December 2007 (UTC)[reply]

Apoapsis and Periapsis

[edit]

The infobox gives apoapsis and periapsis as 200 km. This puts the vehicle well below the surface of the moon, since those figures refer to the distance from the centre of mass of the system. —Preceding unsigned comment added by Ronstew (talk • contribs) 08:19, 25 January 2008 (UTC)[reply]

Note On Naming

[edit]

should the fact that the name of this mission was based off the chang'e myth be included in some form? --75.193.34.255 (talk) 00:34, 5 May 2009 (UTC)[reply]
