Google has a doodle to commemorate the New Horizons flyby of Pluto.

I love it when science makes great art!
A new global map of water surface temperatures is so visually stunning that it easily may be mistaken for art.

That's it. The last talk has been given. The last drink at the bar has been drunk. And the last goodbyes with old friends have been said. Farewell #LPSC2015. You were a great conference for me.
Till next year....

Dr. P. Boehnke pointed out that only about 50% of all lunar impact samples were heated to temperatures hot enough to reset their Ar/Ar ratios during the impact that formed them. Thus, about 50% of Ar/Ar dates from these samples will show ages that are older than the impact event. This needs to be considered. #lpsc2015

Dr. Pete Schultz gave an amazing talk about the impact that formed South Pole-Aitken (SPA) basin. First he showed spectacular high speed movies of experimental impacts into glass spheres, which demonstrate the disruption and damage that occurs at the antipode of the impact site. These also showed that the antipode of the impact site is not the same as the antipode of the crater for oblique impacts. Next, Dr. Spudis evaluated geological features of SPA , showing that SPA is an oblique impact and that the antipode of the impact site (but not the crater) coincides with the centre of a system of tectonic features related to Procellarum. He thus concludes that the SPA impact would have disrupted the crust under Procellarum, allowing significant melts to form and migrate into the crust. These melts would have differentiated, forming a KREEP layer that was later exposed by the Imbrium impact event. Wow!! #lpsc2015

Interesting point about the antipode of the impact changing if the impact is oblique....

Dr. H. Nekvasil conducted experiments that show how crystallization of plagioclase under high pressures can make the plagioclase more anorthitic with cooling. At low pressures, cooling plagioclase becomes more albite-rich, making it difficult to explain the high anorthite content of the lunar highlands crust. Dr. Nekbasil's work suggests the highland plagioclases could have cooled under higher pressures at depth in the lunar mantle and then been transported to the surface.

Dr. Rebecca Ghent looked at radar data of the lunar regolith and found that rocks on the surface break down and disappear within about 1 billion years. Rocks within the regolith, on the other hand, persist for long periods of time, well beyond their brethren on the surface.

Awesome photo of the Space Station crossing the Moon. Read the article to find out just how hard it was to get this shot!
As the International Space Station (ISS) zoomed over Australia on June 30, Dylan O'Donnell captured this amazing view of the orbiting lab crossing in front of the moon.

Zack Morse is doing some great work mapping the ejecta of Orientale basin on the Moon. This impact has been mapped before, but the last extensive work on this was in 1977. Zack is re-visiting these deposits using more recent data sets like the LROC WAC and NAC images. #lpsc2015

One of the themes for the Moon at LPSC this year has been the composition of the lunar mantle. Considering the variety of studies and findings, it is clear that we really don't know what the lunar mantle is made of.  #lpsc2015

A big thank you to Scott at the JMARS booth, who took time during Thursday's poster session to try and solve my JMARS issues.
