Project Progress

Accretion modeling coupled with D/H data produced consistent water delivery scenarios for Earth and Mars (Lunine et al., 2003).

Preliminary results from terrestrial and experimentally shocked minerals showed low D-enrichment, supporting the hypothesis that high D/H rations in Martian rocks do not result from shock (Minitti et al, in prep.).

Carbonaceous chondrite analyses provided constraints on aqueous environments on asteroids (Airieau et al., 2003; Benedix et al., 2003).

C isotope data provided new constraints on magmatic and surficial carbon reservoirs in the Martian carbon cycle (Goreva et al., 2003, Niles et al., in prep.).
