Presumably they will go into a polar orbit to cover the surface every 14 days. What is the planned orbital period ? 1.5 to 2hrs ? Moon Circumference (equatorial) 10,921 km suggests the ground track (at equator) of each orbit will shift by how many km (~25-30km?) ? - Rod57 (talk) 10:42, 2 September 2011 (UTC)[reply]
I don't see any need for the launch attempt table to be sortable (on the columns). Bubba73 You talkin' to me? 03:54, 11 September 2011 (UTC)[reply]
I was curious what was used to make these satellites reach the moon (given it has taken them a couple of months since launch), expecting some information about that (and frankly, expecting they were using ion drives or such). That information (if made available in a form that is acceptable to use on Wikipedia) would be valuable for the article. (If nobody objects and I find time, I can try to dig on NASA's web site...) --IllvilJa (talk) 09:17, 30 December 2011 (UTC)[reply]
0.1 micron is not half the width of a human hair. The washington post articlehttp://www.washingtonpost.com/blogs/innovations/post/nasa-to-crash-probes-into-the-moon/2012/12/17/2f2d2b80-4871-11e2-b6f0-e851e741d196_blog.html got it wrong, as did their source, the NASA article http://www.nasa.gov/mission_pages/grail/news/grail20120327.html .
From Hair "The diameter of human hair varies from 17 to 180 micrometers..."
I can't easily find anything of this order of magnitude, perhaps a virus, but they vary a lot. I've deleted the reference to a human hair for now. Perhaps someone else can add a physical-world analogue to the article.

Now digging to find the actual accuracy, the best reference is this:
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120009915_2012010042.pdf
(you might need google cache) shows that the ultimate performance of the ranging system seems to be just under 1 micron, depending on the averaging time. It is a stretch to say it could achieve 0.1 micron.
So the original article is wrong in both ways.
I've updated the article to reference the NASA PDF, and called the range about 1 micron.

Gravity Recovery and Interior Laboratory → GRAIL – In line with the naming conventions for spacecraft on Wikipedia. There is no disambiguation for the all-caps "GRAIL" name. The existing link is, in fact, a redirect to this article. Other examples of this naming convention include LCROSS, MESSENGER, STEREO, SMART-1, and NEAR Shoemaker. WP:COMMONNAME is also applicable in this circumstance, as "GRAIL" is referenced as the mission's name more than its full title. NASA never uses its full title outside a lead sentence, opting to use the acronym to refer to the spacecraft frequently in press releases (Examples 1, 2, 3). The official NASA Solar System Exploration entry for the mission is "GRAIL" The spacecraft's manufacturer Lockheed Martin uses the "GRAIL" name liberally, and news coverage almost exclusively uses the "GRAIL" name in both capitalised and non-capitalised forms (Examples 1, 2) – PhilipTerryGraham (talk · contribs · count) 21:34, 19 February 2018 (UTC)[reply]
