Planetary scientists sharing ideas and discoveries.

Planetary Science Research Discoveries (PSRD) is an educational site sharing the latest research being made by NASA-sponsored scientists on meteorites, planets, and other bodies in our Solar System. The website is supported by the Cosmochemistry Program of NASA's Science Mission Directorate and by Hawai'i Space Grant Consortium and is a vital link for planetary and space sciences, and for learning how science works.

Supported by NASA's Cosmochemistry Program and Hawai'i Space Grant Consortium.

Archive of PSRDpresents Slide Sets

These annotated slide sets are associated with PSRD articles, which provide the full context, additional graphics, and references. If your browser does not open the notes associated with the slides, then please download the file to view the entire presentation. Beginning in November, 2009 we use .pptx file extension (files created before this date use .ppt extension). We hope you find the slides useful for your own talks and presentations.

DATE POSTED	PSRDpresents (PowerPoint Slides)	ARTICLE
13 NOV 09	An Even More Precise View of Aluminum-26 in the Solar Nebula New, precise analyses of the short-lived isotope aluminum-26 indicate it was distributed uniformly throughout the early solar system, an important clue to its origin.	Al-26-distribution.html PSRD-Al-26-distribution.pdf
26 OCT 09	Kaidun--A Meteorite with Everything but the Kitchen Sink This unique breccia is called a single-stone meteorite collection.	Kaidun_meteorite.html PSRD-Kaidun_meteorite.pdf
18 SEPT 09	The Growing Diversity of Lunar Basalts A lunar basaltic meteorite adds complexity to the already complicated story of mare basalt volcanism on the Moon.	NWA032.html PSRD-NWA032.pdf

8 MAY 09	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.	Mars.Basaltic.Crust.html PSRD-Mars.Basaltic.Crust.pdf
25 MAR 09	Time to Solidify an Ocean of Magma A small mineral grain places limits on how long it took the lunar magma ocean to solidify.	magmaOceanSolidification.html PSRD-magmaOceanSolidification.pdf
19 FEB 09	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.	asteroidalMagmas.html PSRD-asteroidalMagmas.pdf
27 JAN 09	The Crazy Mixed-Up Lunar Crust The horizontal and vertical distribution of well-mixed basin ejecta has lunar-wide geochemical ramifications.	lunarBasins.html PSRD-lunarBasins.pdf
14 DEC 08	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.	cometDust.html PSRD-cometDust.pdf
20 NOV 08	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.	chondrule_sodium.html PSRD-chondrule_sodium.pdf
22 SEPT 08	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.	MoonWater.html PSRD-MoonWater.pdf
8 JULY 08	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.	H-chondrite-parent.html PSRD-H-chondrite-parent.pdf
30 MAY 08	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?	MetsOnMars.html PSRD-MetsOnMars.pdf
29 APRIL 08	A Farside Geochemical Window into the Moon Findings show geochemical enhancements in the Dewar region are caused by thorium-rich mare basalt fragments in the regolith.	Dewar-Th.html PSRD-Dewar-Th.pdf
22 FEB 08	Compositional Balancing Before Moon Formation The identical oxygen isotopic composition of Earth and Moon might be explained by exchange of material between the proto-Earth and the surrounding proto-lunar disk.	EarthMoonFormation.html PSRD-EarthMoonFormation.pdf
19 DEC 07	Chips Off an Old Lava Flow Lunar meteorite Kalahari 009 contains fragments of basalt about 4.35 billion years old, a record-breaking old age for mare basalt.	cryptomareSample.html PSRD-cryptomareSample.pdf
27 NOV 07	Getting to Know Vesta Scientists are primed with geochemical data from HED meteorites for Dawn's encounter with asteroid 4 Vesta.	HEDs-Vesta.html PSRD-HEDs-Vesta.pdf
30 OCT 07	Did an Impact Make the Mysterious Microscopic Magetite Crystals in ALH84001? Tiny crystals of magnetite in Martian meteorite ALH 84001 might have been made when shock waves decomposed iron carbonate.	magnetite-origin.html PSRD-magnetite-origin.pdf
