Amendment 64: New Opportunity: A.15 Biosphere - NASA Science (.gov)

New Program Element A.18 Geosphere solicits proposals addressing one or more of the following sub-elements: Forecasting of geohazards and/or assessment of their impact on the Earth System. Proposals focused on this subelement may explore one or more geohazard types, and proposals that seek to characterize process-based connections between hazard cascades (for example, earthquake triggers leading to tsunami or landslides) are strongly encouraged. Proposals seeking to explore forecasting of geohazards could include volcanic deformation analyses or monitoring and modeling of pre-seismic activity. For proposals incorporating analyses of how hazards impact infrastructure or populations, proposers should seek to connect to societal impacts to align with Earth Science to Action objectives.

Lawrence Livermore National Laboratory researcher Isaiah Santistevan led the development of three-dimensional simulations exploring how a nuclear device could deflect or disrupt an asteroid threatening Earth.
