A major bottleneck in determining appropriate mitigation methods for Near-Earth Objects (NEOs) has been a lack of experimental data on the efficacy of each approach, forcing a reliance on simulations to determine mission effectiveness. As we move from the concept stage into true mission planning for effective NEO threat mitigation, we must depart fromâ€¦ (More)

An intercept mission with nuclear explosives is the most effective of the practical mitigation options against the impact threat of near-Earth objects (NEOs) with a short warning time (e.g., much less than 10 years). The existing penetrated subsurface nuclear explosion technology limits the intercept velocity to less than approximately 300 m/s.â€¦ (More)

Attempts to deflect a near-Earth object (NEO) from an impact trajectory using high-energy methods, such as nuclear explosions, can plausibly fragment the NEO rather than deflect it. This paper addresses the orbital dispersion problem of a fragmented NEO using the asteroid 99942 Apophis as a model, and presents a physical description of the relative motionâ€¦ (More)

This paper considers the problem of developing statistical orbit predictions of nearEarth object (NEO) fragmentation for nuclear disruption mission design and analysis. The critical component of NEO fragmentation modeling is developed for a momentum-preserving hypervelocity impact of a spacecraft carrying nuclear payload. The results of the fragmentationâ€¦ (More)

The Florida Institute of Technology developed the Orbital Robotic Interaction, On-orbit servicing, and Navigation (ORION) laboratory for the testing of spacecraft guidance, navigation, and control systems for spacecraft proximity maneuvers, and autonomous or telerobotic capture. ORION combines the precise kinematics simulation and large load-bearingâ€¦ (More)

Orbit determination and control problems are sometimes solved using linearized methods, even though nonlinear effects can sometimes dominate the system. This paper addresses ways to parallelize computational algorithms for numerical integrators and nonlinear relative motion equations. An application of the proposed methods to mutual gravitation of aâ€¦ (More)
