Indeed it is; world-class real science explanation, as per her usual.
So that's what happens when you give a talented planetary geologist a computer with word processing capability... 
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Just a reminder
UPCOMING EVENT: NASA Moon Mission News 10:30 a.m. PST (13:30 EST) Thursday, Dec. 13 (18:30 UTC) LINK http://www.ustream.tv/nasajpl2 NASA will host a media teleconference to provide an overview of events leading up to twin spacecraft being commanded to impact the moon's surface on Dec. 17 at approximately 14:28 PST, (17:28 EST). (22:28 UTC) NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, whose two washing machine-sized probes were named Ebb and Flow by elementary school students in Bozeman, Mont., via a nationwide contest, have successfully completed their prime missions and have only days to go on their extended mission science collection. As planned, the duo is running low on fuel. They have been orbiting the moon since New Year's Eve and New Year's Day, respectively, giving scientists unprecedented detail about the moon's internal structure and composition. |

Had no idea they 'caught' LRO up to now. Fascinating!

The scattered fragments will be the most northerly artifacts on the lunar surface, for a while.

And speaking of locations... on the posted graphic the longitude is given as 26.63 degrees East. Oops - it's West! Yes, west of the prime meridian. You could call it 333.37 E if you prefer. Maybe that wacky lunar gravity is playing with the trajectory.
(I just noticed Emily has it right in her blog - well done!) Phil -------------------- ... because the Solar System ain't gonna map itself.

On the other side of the quality scale from Emily's fantastic work we have this from The Grauniad: http://www.guardian.co.uk/science/2012/dec...issance-orbiter
Someone alert the Planetary Protection Officer! |

Let's hope they splash down safely!

QUOTE (SFJCody @ Dec 13 2012, 11:53 PM)  Someone alert the Planetary Protection Officer! I read the article and couldn't see any major problems. However, when I got to the bottom there was an announcement. http://www.guardian.co.uk/science/2012/dec...issance-orbiter "This article was amended on 14 December to amend the subheading, which originally said the probes would "splash down" on the moon. The photograph was also changed; the original showed Saturn's moon Enceladus."

That cross-section chart updating every couple seconds is so cool. Minute left...
And it's done. Goodnight, grail. It's up to LRO to see what it can see when the sun comes up.... |
