Migration of Jupiter-family comets and resonant asteroids to near-Earth space [PDF]

arXiv, 2003
We estimated the rate of comet and asteroid collisions with the terrestrial planets by calculating the orbits of 13000 Jupiter-crossing objects (JCOs) and 1300 resonant asteroids and computing the probabilities of collisions based on random-phase approximations and the orbital elements sampled with a 500 yr step.

What fuel for a rocket? [PDF]

Revista Mexicana de Fisica, 49, 191 (2003), 2012
Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel.
