Near - Earth Objects
Because the NEO population is constantly evolving and being replenished from the main asteroid belt and cometary reservoirs, it consists of objects with a variety of compositions and internal structures. These objects present unique opportunities for future planetary science goals and exploration. In order to realize these opportunities for future NASA studies, an expanded program for NEO disco...
متن کاملInvestigate probability of damage of Earth dam under Near-field and Far –field earthquake : Case study Gotvand earth dam
The main goal of preset research is investigate the effects of vertical component of Near-Fault and Far-Field earthquake records on the probability of overtopping induced damage of earth dam due to the reduction of freeboard due to the settlement of dam crest. In this respect 12 different earthquake record are selected. Nonlinear dynamic analysis of earth dam is implemented with FLAC 3D using F...
متن کاملOrigin and Evolution of Near-Earth Objects
Asteroids and comets on orbits with perihelion distance q < 1.3 AU and aphelion distance Q > 0.983 AU are usually called near-Earth objects (NEOs). It has long been debated whether the NEOs are mostly of asteroidal or cometary origin. With improved knowledge of resonant dynamics, it is now clear that the asteroid belt is capable of supplying most of the observed NEOs. Particular zones in the ma...
متن کاملAn Enhanced HL-RF Method for the Computation of Structural Failure Probability Based On Relaxed Approach
The computation of structural failure probability is vital importance in the reliability analysis and may be carried out on the basis of the first-order reliability method using various mathematical iterative approaches such as Hasofer-Lind and Rackwitz-Fiessler (HL-RF). This method may not converge in complicated problems and nonlinear limit state functions, which usually shows itself in the f...
متن کاملComet/asteroid Protection System (caps): a Space-based System Concept for Revolutionizing Earth Protection and Utilization of Near-earth Objects
There exists an infrequent, but significant hazard to life and property due to impacting asteroids and comets. There is currently no specific search for long-period comets, smaller near-Earth asteroids, or smaller shortperiod comets. These objects represent a threat with potentially little or no warning time using conventional ground-based telescopes. These planetary bodies also represent a sig...
