CLPS Landing Site at a Young Thrust Fault Scarp Cluster [#8027]
With the detection of a global population of young thrust fault scarps, the investigation of these potentially active faults is a major priority.  We propose a CLPS landing site to investigate a cluster of these scarps and their associated seismicity.

Ina:  Recent Lunar Volcanism? [#8012]
Crater distributions suggest that volcanic landform, Ina, formed <100 Mya. This contradicts the results of thermal evolution models which suggest that lunar volcanism ended >1 Gya. In situ geochronology or sample return could resolve this conflict.

Robinson M. S. *   Denevi B. W.   Speyerer E. J.

Ina – Old or Young [#8034]
Ina is an enigmatic landform thought to have formed as a result of basaltic volcanic processes. One hypothesis proposes that Ina formed <100 my ago, and another >3.0 by ago. We will test these competing hypotheses to determine the age of Ina.

12:55 p.m.

Speyerer E. J. *   Robinson M. S.

Understanding the Impact Process by Exploring a Newly Formed Impact Crater [#8031]
