Trails of OH emissions from small comets near Earth
The results are reported for a successful search for the OH emissions associated with an influx of small comets into Earth's upper atmosphere with a camera on board the Polar spacecraft. The spatial distributions of the OH emissions are characterized by a bright core of intensities at or less than the spatial resolution of the camera which is surrounded by a larger dim region of luminosities. T...
متن کاملMigration of Small Bodies and Dust to Near-Earth Space
The orbital evolution of Jupiter-family comets (JFCs), resonant asteroids, and asteroidal, trans-Neptunian, and cometary dust particles under the gravitational influence of planets was integrated. For dust particles we also considered radiation pressure, Poynting-Robertson drag, and solar wind drag. The probability of a collision of one former JFC with a terrestrial planet can be greater than a...
متن کاملYarkovsky Effect on Small Near-Earth Asteroids: MathematicalFormulation and Examples
The Yarkovsky effect is a subtle nongravitational phenomenon related to the anisotropic thermal emission of Solar System objects. Its importance has been recently demonstrated in relation to the transport of material from the main asteroid belt (both to explain the origin of near-Earth asteroids and some properties of meteorites) and also in relation to the aging processes of the asteroid famil...
متن کاملapplication of passive gg-aero stabilization for near-earth small satellites
when the orbital altitude of a small satellite is near-earth, passive stabilization can be considered. the purpose of this paper is to combine the passive gravity gradient and aerodynamic stabilization methods together so that all the three axes stabilizations can be obtained. in this regard, the set of nonlinear equations of motion will be solved numerically with specified initial condition. t...
متن کاملCapturing near-Earth asteroids around Earth
The list of detected near-Earth asteroids (NEAs) is constantly growing. NEAs are likely targets for resources to support space industrialization, as they may be the least expensive source of certain needed raw materials. The limited supply of precious metals and semiconducting elements on Earth may be supplemented or even replaced by the reserves floating in the form of asteroids around the sol...
