NASA's Lunar Reconnaissance Orbiter (LRO) launched at 5:32 p.m. EDT on June 18, 2009 and entered orbit around the Moon four and a half days later. LRO will perform reconnaissance of Earth's nearest neighbor in space in preparation for human return around 2020. LRO Homepage.
New Job Opportunity: Antarctic Meteorite Recovery and Planetary Research. This is a Postdoctoral position with Dr. Ralph Harvey. For details: http://geology.cwru.edu/~ansmet/postdoc_ad.pdf Review of applications will begin immediately and continue until the position is filled. [Posted June 10, 2009.]
A workshop on "Experimentation and Modeling in Cosmochemistry" is planned for July 11-13, 2009 in Nancy, France prior to the annual Meteoritical Society Meeting. For more information please see the Workshop Website.

Mars Crust: Made of Basalt
Chemical analyses of rocks on the Martian surface indicate that the Martian crust was built of basalt lava flows not much different from those on Earth.
Better Know A Meteorite Collection: Natural History Museum in Vienna, Austria
PSRD highlights places and people around the world who play central roles in caring for and analyzing meteorites.
Time to Solidify an Ocean of Magma
A small mineral grain places limits on how long it took the lunar magma ocean to solidify.
More Evidence for Multiple Meteorite Magmas
Cosmochemists show that a pair of meteorites formed in an asteroid that erupted a newly-recognized type of asteroidal magma.
The Crazy Mixed-Up Lunar Crust
The horizontal and vertical distribution of well-mixed basin ejecta has lunar-wide geochemical ramifications.
Wee Rocky Droplets in Comet Dust
Tiny flash-melted objects in dust collected from comet Wild 2 were transported from the inner Solar System to the outer reaches where comets formed.
Tiny Molten Droplets, Dusty Clouds, and Planet Formation
Roughly constant sodium concentration during chondrule crystallization suggests that these molten droplets formed in regions of the solar nebula that were enriched in rocky dust.
The Bone-Dry Moon Might be Damp
Cosmochemists have written in stone that the Moon is almost totally devoid of water, but new analyses of volcanic glasses suggest that they need to do some editing.
Heating, Cooling, and Cratering: One Asteroid's Complicated Story
Cooling rate data indicate that the H-chondrite parent asteroid was deeply cratered as it cooled slowly.
Meteorites Found on Mars
No surprise that there are meteorites on other planets. Now that we've seen them on Mars, what do we know about them and what does their geochemistry tell us about the environment where they landed?
In this series of articles PSRD highlights the essential tools and amazing technology used by talented scientists seeking to unravel how the solar system formed.
This section of PSRD contains annotated slide sets that are associated with our articles. We hope you find the slides useful for your own talks and presentations.
