Interplanetary Meteoroid Environment Model Update
Journal of Spacecraft and Rockets, 1998The effects of the sporadic meteoroid environment on interplanetary spacecraft have an important impact on mission design. A reformulation is described of the Divine interplanetary meteoroid model, called the meteoroid engineering model (METEM), that is capable of estimating many ofthoseeffects.

Conference summary: Meteoroids
Earth, Moon, and Planets, 1996Summarizing our meeting for its meteoroid part is mostly the task of definition, what meteoroids are. Some are certainly small pieces of comets as we know from meteor-stream comet associations. Jewitt in his invited talk draw our attention to definition of terms: asteroid and comet. It is certainly used as phenomenalistic description of the bodies, but

RADAR MEASUREMENTS OF METEOROID DECELERATIONS
Earth, Moon, and Planets, 2004Measurements of meteoroid velocities and decelerations have been obtained from post-t 0 diffraction patterns present in echo signatures obtained from the multi-site AMOR radar operated at the University of Canterbury’s research facility. The system allows the sampling of a meteoroid’s velocity at separated points along the body’s trajectory to yield ...

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">The effects of meteoroid protection weight requirements on space exploration costs are examined. A basis is developed for selecting upper and lower bounds to the acceptable risk. The quality of present knowledge of the meteoroid environment and of hypervelocity impact penetration is reviewed.

Science, 1974
Data on interplanetary and near-Jupiter micrometer-sized particle encounters from the meteoroid-detection experiment on Pioneer 10 indicate that Jupiter is much 'dustier' than interplanetary space. Whereas the near-earth particulate flux showed very little increase over the interplanetary flux, the near-Jupiter penetration flux was over two orders of ...

Solar System Research, 2001
The density of the Galactic meteoroid background formed by the loss of large dust grains escaped from circumstellar disks during the formation of a star is estimated. This density is shown to be substantially higher than the local density of meteoroids that escaped from dusty stellar disks as a result of two-star collisions.

The size of meteoroid constituent grains: Implications for interstellar meteoroids
2002The most widely accepted model for the structure of cometary meteoroids is a dustaball with grains bound together by a more volatile substance [1]. In this paper we estimate the size distribution of dustball grains from meteor flare duration, using image intensified CCD or 1998 Leonid meteors.

We have already mentioned repeatedly the great significance of the fragmentation of meteoroids (see Sections 20, 31, and 34). Now let us consider the main observational data attesting to this phenomenon [194]: (1) a high rate of ablation and, as a result, shorter trajectories and higher fadeout altitudes than are to be expected from the ...

Probability of meteoroidal penetration
AIAA Journal, 1964The past technique of calculating the flux of meteoroids capable of penetrating the skin of a spaceship is critically reviewed A new, more rigorous technique, compatible with any assumed meteoroidal flux, velocity distribution, and penetration equation, is derived using integral calculus Several values of a constant convenient for calculating the ...

Ablation is defined as a removal of meteoroid mass via phase transformations of the solid surface layer to the liquid or gaseous state. Ablation involves: (a) fusion of the outer layer, followed by spraying of the liquid layer by the oncoming air flow; (b) vaporization of the solid phase or liquid layer, and removal of mass in the ...
