GRIMM'S CURRENT RESEARCH

Measurement of scattering and absorption losses in ground-penetrating radar, with implications for understanding the subsurface properties of Mars Grimm et al., 2006a; Heggy et al., 2006a,b).

Instrumentation and missions for geophysical exploration of Mars, the Moon, and asteroids.

Laboratory NMR assessment of the abundance of interfacial ("unfrozen") water at subfreezing temperatures of Mars-analog materials, in order to understand possible habitability of the near-surface. Measurement of the low-frequency and radiofrequency properties of interfacial water for remote-sensing assessment (Grimm et al., 2006b).

Modeling groundwater flow on ancient Mars; assessing potential recharge zones and effects of climatic variation; mapping effects of outflow discharge (Keith Harrison, Science PI).

Joint thermal and collisional modeling of ordinary chondrite parent bodies (Grimm et al., 2005).

Hydrothermal circulation and aqueous alteration on carbonaceous chondrite parent bodies.
