TL;DR: In this article, the authors derived the Hugoniot equations for impact cratering, and derived the state of the art for the state for the impact crater problem in the United States.

TL;DR: The molecular laboratory model of spore resistance mechanisms is summarized and attempts to use the model as a basis for exploration of the resistance of spores to environmental extremes both on Earth and during postulated interplanetary transfer through space as a result of natural impact processes.

TL;DR: A large increase in organic material occurred during and after the event, with smaller changes in carbon dioxide relative to water, and a thermal map indicates a surface in equilibrium with sunlight.

TL;DR: In this article, a series of three-dimensional numerical simulations of the collision between the earth and an object of about 1/10 its mass is presented, where assumptions, the equation of state, numerical techniques utilizing the momentum equation and the energy conservation equation, tests, and initial conditions and units are given.

TL;DR: In this article, a detailed study of the production of melt and vapor in planetary impact events is carried out with hydrocode simulations, where Sandia's two-dimensional axisymmetric hydrocode CSQ was used to estimate the amount of melting and vapor produced for widely varying initial conditions: 10 to 80 km/sec for impact velocity, 0.2 to 10 km for the projectile radius.
