[IGPP Everyone] Congrats to EPSS cosmochemists Young, Kohl, and Warren

[Kevin McKeegan]

Hi Everyone.  Here's a smashing news item:


Congratulations to Ed Young, Issaku Kohl, Paul Warren, and their
collaborators on their paper “Oxygen isotopic evidence for vigorous mixing
during the Moon-forming giant impact” which appears in tomorrow’s edition
of Science.  Using their new Panorama high-resolution mass spectrometer,
the team has performed ultra-high precision oxygen isotope analyses of
lunar samples.  The compositions match those of Earth’s mantle rocks to
within a few parts-per-million (in the Δ17O parameter), demonstrating that
the Earth and Moon formed from the exact same reservoir of well-mixed
material.  Their data also constrain the composition of the so-called “late
veneer” materials added to the Earth after the Moon-forming impact.


A shout-out also goes to the UCLA Panorama instrument, a photo of which
appears in an editor’s news item accompanying the article.  You can read
about it here
<http://science.sciencemag.org/content/351/6272/431.full-text.pdf+html>  or
you can see it for yourself, literally, by looking through the picture
window at the west-end of the first floor of Geology!

Congratulations Ed, Issaku, and Paul.
