Description

About the NASA Postdoctoral Program

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Description:

Understanding the potential threat to earth due to asteroid impact is an interdisciplinary pursuit which requires studying the population of near earth asteroids and their properties, how an asteroid behaves as it passes through the earth's atmosphere and the damage caused by airbursts, ground impacts and tsunamis. In addition, assessing this threat can require probabilistic models of the effects of impact and possible mitigation options in order fully understand the range of possible outcomes.

Opportunities exist to participate in all areas of the asteroid threat assessment. Some of the active areas of research in planetary science include observational studies of near earth asteroids, modeling their thermal emission, inferring asteroid properties from meteorites, and developing representations of the distribution of physical parameters of the entire population. Areas of research in atmospheric entry include experiments and models to elucidate the behavior of asteroid material during atmospheric entry, modeling of fragmentation during entry, aerothermodynamics of asteroid entry, and the aerodynamics of multi-body flight. Impact hazard research involves the creation of reduced order models that are based on detailed simulations but are computationally efficient enough to run inside a Monte Carlo framework requiring millions of evaluations. Particular hazards of interest are ground winds, overpressure, and thermal radiation produced by airburst and impact cratering events, tsunami produced by ocean impacts, and regional/global climatic changes due to large impacts. Research related to risk modeling includes incorporation of improved reduced-order hazard models into the Monte Carlo framework. In addition, inclusion of mitigation options into the probabilistic asteroid impact risk model is an ongoing area of research.
