Atmospheric Secondary Particles In Near Earth Space
In June 1998, the Alpha magnetic spectrometer AMS [1] had a test flight on board space shuttle and recorded some 108 events. The AMS proton and leptons spectrum [2, 3] have a magnetic latitude dependence. The spectral shape of primary cosmic rays can be explained by the geomagnetic rigidity cutoff. However, below the rigidity cutoff, a second spectrum was clearly seen. The energy of this second...
متن کاملThe Near-Earth Space Radiation for Electronics
The space radiation environment can have serious effects on spacecraft electronics. For example, accumulated damage from electron and proton exposure will limit system endurance. Transient effects from individual high-energy protons or cosmic rays can disrupt system operation, perhaps irreversibly. Of particular importance in assessing the impact of the space radiation on electronic devices are...
متن کامل1 Science and Technology Text Mining : near - Earth Space
Database Tomography is a patented system for analyzing large amounts of textual computerized material. It includes algorithms for extracting multi-word phrase frequencies and performing phrase proximity analyses. This report shows how Database Tomography can be used to derive technical intelligence from the published literature. One potential application of Database Tomography is to obtain the ...
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 کاملLaboratory Investigation of Near - Earth Space Plasma Processes
Introduction: Energetic particles and plasma dynamics in the near-Earth space environment can significantly impact operation of both military and civilian systems. The underlying physical mechanisms relevant to two important space plasma issues, radiation belt dynamics and auroral ionospheric space weather, are under investigation in the NRL Space Physics Simulation Chamber (SPSC). Plasma condi...
