A radioactive power source emplaced between a dry martian surface layer and underlying icy regolith can result in meltwater that persists for weeks or months.

Summary: We describe the response of icy martian soil to a localized heat source using analytical and numerical models. Our motivation is to understand the implications of a landing failure in which a radioisotope power source is deposited along with terrestrial microbes within or near icy regolith, resulting in the production of liquid water and the proliferation of microbes.
