▪ Abstract The detailed morphology of impact craters is now believed to be mainly caused by
the collapse of a geometrically simple, bowl-shaped “transient crater.” The transient crater …

The global high‐resolution imaging of asteroid 433 Eros by the Near‐Earth Asteroid
Rendezvous (NEAR) Shoemaker spacecraft has made it possible to develop the first …

We use a smooth particle hydrodynamics method to simulate colliding rocky and icy bodies
from centimeter scale to hundreds of kilometers in diameter in an effort to define self …

Martian moons exploration, MMX, is the new sample return mission planned by the Japan
Aerospace Exploration Agency (JAXA) targeting the two Martian moons with the scheduled …

We describe a version of the smooth particle hydrodynamics (SPH) method suitable for
modeling solids. The model includes strength and implements a von Mises yielding relation …

The probability distribution for impact velocities between two given asteroids is wide, non-
Gaussian, and often contains spikes according to our new method of analysis in which each …

We describe a new numerical tool based on the smooth particle hydrodynamics (SPH)
method which is aimed at modeling impacts and collisions involving small solid objects. Our …

A statistical model of a tensile strength is implemented into the SALE-2D hydrocode. The
well-tested 2D code has been modified to handle multi-material problems and strength …

A survey of particle impact phenomena is provided with a particular emphasis on impacts
resulting in the so-called cold spray phenomenon, ie, in a strong adherence of particles to …

Hubble Space Telescope images of asteroid 4 Vesta obtained during the favorable 1996
apparition show an impact crater 460 kilometers in diameter near the south pole. Color …
