This is absolutely a case where space nerds win out over linguist nerds. The name is only pretending to be Greek. The moon is actually named after the discoverer's wife and is just modified slightly to look like it's mythological, to pass IAU inspection.

The early, distant detection of ionized nitrogen seems to be the most unexpected thing thus far.
Presser wrapping up. -------------------- 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.

Does anyone have an estimate of how much of Pluto will not be imaged at all? Either because it's in the dark or just due to the geometry of the encounter?
Best would be a contour map showing resolution in different regions, but just a measure of the invisible amount would be interesting. Same for Charon. |

If I followed Dr. Stern correctly, molecular nitrogen was found five days out of closest approach. Actually at that distance it was ionized nitrogen and is believed to have come from Pluto. The detection was significantly further out than had been expected which *implies* some type of more energetic release mechanism on Pluto. However, the data resolution is too low to really tell at this point.
Also, the methane signature of Pluto's dark regions is significantly lower than that of the polar region. We all get to add this new information to our image interpretations... Andy |

New version of my Pluto map where I have added the 2015-07-11 22:23 image that was released by the NH team last night if I remember correctly (things are happening fast now!). Longitude 0 is at the left edge of the map.
Of course this is probably only hours (or possibly even minutes) from getting completely outdated - and if I want to keep the map up to date I soon need to make a bigger version. |

Next media event will be tomorrow 14 Jul/1130 GMT for closest approach, followed by a presser/image release.

Is the media conference going to be uploaded to youtube? I missed it.

QUOTE (nprev @ Jul 13 2015, 11:42 AM)  Next media event will be tomorrow 14 Jul/1130 GMT for closest approach, followed by a presser/image release. Things are happening fast now. As mentioned in a previous briefing, we may not see all the data for awhile. But I'm sure they will put out some images and data this week. I "accidentally" took a screen grab from a monitor during a live feed from NH Mission Operations today:
It sure doesn't look like telemetry data. Although it's too small to be useful, if it is an image of Pluto or Charon, it could be a teaser of the kind of resolution and detail we can soon expect. Personally, I think it could be a close up on Pluto... |

Björn's map illustrates how the bright areas to the west in the last image release is probably (at the least) a half-decent preview of the rest of heart feature. The bright stuff here is probably similar to the bright stuff in the rest of it. Judging by lower-resolution maps, there were already solid hints that this part would not be some sort of uniform white, however.

The fact that our closest approach view will include the brightest region and part of the dark region together with other parts in between albedos ,should give us a good representation of all terrain types visualized so far on pluto.

Just updated the New Horizons image database: http://nchazarra.duckdns.org/db/
Now you can also download the whole records in .csv. |
