A powerful theme that permeated the conference is that the key to the search for martian extant life lies in identifying and exploring refugia (i.e., "oases"), where conditions are either permanently or episodically significantly more hospitable than average, that is, the "Refugium Model." Martian life, if it was once more widespread . Separating the chemical signatures of the coatings, the underlying rock, and the ever-present dust on the Martian surface is complex. The Phoenix is capable of performing the same chemical analysis on three more samples. The combination of in situ measurements and element correlations obtained by the martian meteorites implies an ancient basaltic crust with high abundances of incompatible elements (K, Rb, Nd, U .
