Near - Earth Objects

چکیده
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 discovery and characterization should be undertaken, and NEO exploration and sample return spacecraft missions should be developed and implemented over the next decade (2013-2022), both for scientific and exploration considerations. 1 Subdiscipline Overview 1.

Asteroid Destinations Accessible for Human Exploration: A Preliminary Survey in Mid-2009
Theflexible path is one of several space exploration strategy options developed by theReview ofU.S.HumanSpace Flight Plans Committee in 2009. Among proposed flexible path destinations are near-Earth objects, those asteroids and comets having perihelions of less than 1.3 astronomical units and periods of less than 200 years. Heliocentricorbit element criteria have been developed with the objecti...
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 کاملThe Euphrosyne Family’s Contribution to the Low Albedo Near-earth Asteroids
The Euphrosyne asteroid family is uniquely situated at high inclination in the outer Main Belt, bisected by the 6 n secular resonance. This large, low albedo family may thus be an important contributor to specific subpopulations of the near-Earth objects. We present simulations of the orbital evolution of Euphrosyne family members from the time of breakup to the present day, focusing on those m...
متن کاملMigration of small bodies and dust to the terrestrial planets
We integrated the orbital evolution of 30,000 Jupiter-family comets, 1300 resonant asteroids, and 7000 asteroidal, trans-Neptunian, and cometary dust particles. For initial orbital elements of bodies close to those of Comets 2P, 10P, 44P, and 113P, a few objects got Earthcrossing orbits with semi-major axes a<2 AU and moved in such orbits for more than 1 Myr (up to tens or even hundreds of Myrs...
متن کاملInto the Beyond: a Crewed Mission to a Near-earth Object
ABSTRACT Aside from the exploration of Mars, the objects that most capture our interest for a new human visit are the Near-Earth Objects (NEOs). These objects are ideal candidates for deep space operations and explorations as we extend the human presence out into the solar system. The notion of a crewed mission to a NEO was first discussed in the Apollo era. The most recent assessment has been ...
متن کاملUNCLASSIFIED PREPARING FOR PLANETARY DEFENSE: Detection and Interception of Asteroids on Collision Course with Earth Subject and Problem Statement
As the Earth revolves around the Sun, it orbits through planetary debris left from the formation of the solar system. Many of the debris objects are asteroids and comets in orbits bringing them close to the Earth and are referred to as Near-Earth-Objects (or NEOs). Of the total NEO population, some portion are in orbits actually intersecting or crossing the orbit of the Earth. The asteroids of ...
