Orbital Deflection of Comets by Directed Energy
Qicheng Zhang, Philip M. Lubin, Gary B. Hughes
Cometary impacts pose a long-term hazard to life on Earth. Impact mitigation techniques have been studied extensively, but they tend to focus on asteroid diversion. Typical asteroi…
Directed Energy Missions for Planetary Defense
Philip Lubin, Gary B. Hughes, Mike Eskenazi +14
Directed energy for planetary defense is now a viable option and is superior in many ways to other proposed technologies, being able to defend the Earth against all known threats.…
Orbital Simulations on Deflecting Near-Earth Objects by Directed Energy
Qicheng Zhang, Kevin J. Walsh, Carl Melis +2
Laser ablation of a Near-Earth Object (NEO) on a collision course with Earth produces a cloud of ejecta which exerts a thrust on the NEO, deflecting it from its original trajectory…
The Transient Optical Sky Survey Data Pipeline
E. Hadjiyska, G. Hughes, P. Lubin +3
The Transient Optical Sky Survey (TOSS) is an automated, ground-based telescope system dedicated to searching for optical transient events. Small telescope tubes are mounted on a t…
Calculating ellipse overlap areas
Gary B. Hughes, Mohcine Chraibi
We present a general algorithm for finding the overlap area between two ellipses. The algorithm is based on finding a segment area (the area between an ellipse and a secant line) g…
