Protecting the Space Shuttle from Meteoroids and Orbital Debris by National Research Council,Division on Engineering and Physical Sciences,Commission on Engineering and Technical Systems,Committee on Space Shuttle Meteoroid/Debris Risk Management Pdf
The space shuttle orbiter has already been struck many times by small meteoroids and orbital debris, but it has not been damaged severely. There is a real risk, however, that a meteoroid or debris impact could one day force the crew to abort a mission or might result in loss of life or loss of the shuttle itself. Protecting the Space Shuttle from Meteoroids and Orbital Debris assesses the magnitude of the problem and suggests changes that the National Aeronautics and Space Administration can make to reduce the risk to the shuttle and its crew.

Lunar Meteoroid Impacts and How to Observe Them by Brian Cudnik Pdf
The genesis of modern searches for observable meteoritic phenomena on the Moon is the paper by Lincoln La Paz in Popular Astronomy magazine in 1938. In it he argued that the absence of observed fashes of meteoritic impacts on the Moon might be interpreted to mean that these bodies are destroyed as luminous meteors in an extremely rarefed lunar atmosphere. The paper suggested the possibility of systematic searches for such possible lunar meteors. With these concepts in mind, I was surprised to note a transient moving bright speck on the Moon on July 10, 1941. It appeared to behave very much as a lunar meteor would – except that the poorly estimated duration would lead to a strongly hyperbolic heliocentric velocity. Thus, the idea of systematic searches for both p- sible lunar meteors and meteoritic impact fashes was born. It was appreciated that much time might need to be expended to achieve any positive results. Systematic searches were carried out by others and myself chiefy in the years 1945–1965 and became a regular program at the newly founded Association of Lunar and Planetary Observers, or ALPO.
Mathematical Modelling of Meteoroid Streams by Galina O. Ryabova Pdf
Modern computer power and high-precision observational data have greatly improved the reliability of meteoroid stream models. At present, scientific research calls for two kinds of models: precise ones for individual streams, and statistically averaged ones for Solar System dust distribution models. Thus, there is a wide field of study open to stream modellers. This brief describes step-by-step computer simulations of meteoroid stream formation and evolution. Detailed derivations of relevant formulae are given, along with plenty of helpful, digestible figures explaining the subtleties of the method. Each theoretical section ends with examples aimed to help readers practice and master the material. Most of the examples are based on the Geminid meteoroid stream model, which has been developed by the author in the last 30 years. The book is intended for researchers interested in meteor astronomy and mathematical modelling, and it is also accessible to physics and astrophysics students.
Meteoroid Threat to Extravehicular Space Suit Assemblies by Frank J. Zimmerman Pdf
This report utilizes most recent meteoroid flux data and illustrates the method used in calculating the probability of meteoroid puncture for a space-suited crewman in earth orbit. An example of the method is shown and uncertainties in the prediction are reviewed. Finally, guidelines are presented that could be followed in planning an experimental program of penetration studies on space suit materials intended to resolve some of these areas of uncertainty.
