Current Issues • Inputs to the Planetary Science Decadal Survey on future potential sample returns from small bodies, Moon and Mars
• Initiation of an independent review of the status of curation of Stardust samples
• Addressing the issue (in collaboration with ESMD personnel through OSEWG) of a recent increase in the number of requests for lunar samples for engineering/resource utilization studies in anticipation of future lunar exploration

Planetary Science Decadal Survey
• Several white papers (in support of sample return from the Moon, Mars and small bodies & of curation and analytical capabilities), some co-sponsored with LEAG and MEPAG, were submitted.
• Presentations made on behalf of CAPTEM to Decadal subpanels.
• CAPTEM-sponsored white papers can be found at: http://www.lpi.usra.edu/captem/publications.shtml

Stardust Curation Status • Stardust returned samples of Comet Wild 2 in January 2006.
• CAPTEM has initiated a review of the status of curation of these samples.
Stardust (Comet Wild 2) Samples: Returned in 2006; thousands of cometary grains in 1000 cm2 of aerogel.
• Review Team: D. Burnett (Caltech, Chair), A. Brearley (UNM), L. Nyquist (NASA JSC), D. Papanasstassiou (JPL), S. Sutton (U Chicago/ANL)

Lunar Samples for ISRU/Engg Studies
• Dialogue with ESMD personnel (initiated through previous OSEWG co-chair Ruthan Lewis, and continuing with new chair Mike Wargo) to provide guidance in prioritization of ISRU/Engg studies utlilizing lunar samples.
• Presentation made at the recent LEAG meeting (Nov 16-19, 2009) regarding CAPTEM’s role in lunar sample allocation.

New Initiatives under Consideration
• CAPTEM sponsored workshop on Lunar Volatiles in Fall 2010
• Mining the Apollo collections for “new” samples: Apollo special samples and lunar breccias
• CAPTEM sponsored workshops on tying sample science to the latest orbital data sets from Moon and Mars
• New opportunities for upper stratospheric timed collections (new cometary materials)
