Conceptual Design and Analysis of Planetary Defense Technology (PDT) Demonstration Missions 

Abstract

When the warning time of the impact threat of a near-Earth object (NEO) is short, the use of nuclear explosives may become necessary to safeguard the Earth. A variety of nuclear options, such as standoff, surface contact, and subsurface explosions, for mitigating the impact threats of NEOs have been prop

osed and studied in the past two decades. Eventually in the near future, an actual flight demonstration mission may become necessary to verify and validate the overall effectiveness and robustness of such various nuclear options and the associated space technologies. This paper presents the conceptual mission architecture design of such flight validation missions with a consideration of three mission cost classifications (e.g., $500M, $1B, and $1.5B).

Biography

George Vardaxis is a first year graduate student under Dr. Bong Wie. He completed his undergraduate degree here at ISU, earning a double major in Aerospace Engineering and Mathematics. His research areas are mission design and precision orbit determination. After graduate school he plans to pursue a career in Astrodynamics/Orbital Mechanics/Mission Design.
