The Impact Cratering Record on Triton
Science, 1990Impact craters on Triton are scarce owing to the relatively recent resurfacing by icy melts. The most heavily cratered surface has a crater density about the same as the lunar maria. The transition diameter from simple to complex craters occurs at a diameter of about 11 kilometers, and the depth-diameter relationship is ...

Calculations are made to determine the sizes of stony and iron meteoroids which could penetrate the atmosphere of Venus and cause hypervelocity impact craters on the planet's surface. Using scaling relationships based on kinetic energy, impact crater size is related to meteoroid size.

Polygonal impact craters on mercury
Planetary and Space Science, 2015The existence of polygonal impact craters (PICs) on Mercury is confirmed by this study, which was performed by analyzing 291 named impact craters greater than 12 km in diameter, photographed by the spacecraft Mariner 10 and MESSENGER. All 15 quadrangles of Mercury were scanned for polygonal impact craters with at least two straight rim segments.

Abstract A summary of experimental and theoretical studies of atmosphere-related phenomena accompanying high velocity impact processes is presented, including asteroid and comet passage through the atmosphere, their impact on the surfaces of different planetary bodies, blast waves in the atmosphere and their influence on surface life. These phenomena

IMPACT! - BOLIDES, CRATERS, AND CATASTROPHES
Elements, 2012It is now universally accepted that the impact of planetesimals, asteroids, and comets has been a fundamental process throughout the Solar System. Catastrophic impact events have been instrumental in developing the early history of the planets and have caused environmental disasters throughout Earth history.

Meteorite impact crater inventory of turkey
Proceedings of 2nd International Conference on Recent Advances in Space Technologies, 2005. RAST 2005., 2006Interplanetary space is populated with large numbers of small bodies known as meteorites, which are in orbits that can intersect those of planets and moons. Therefore, individual impacts appear on the surfaces of planetary bodies which are called impact craters.

Laboratory Craters: Modeling Experiments for Meteorite Impact Craters?
IEEE Transactions on Plasma Science, 2008In this paper, we reveal the feasibility of obtaining laboratory craters to investigate planetary events such as meteorite craters. Experiments were performed by using 0.44-mum laser beam with energy of les15 J in 350 ps (full-width at half-maximum) on aluminum targets.

Impact cratering by high-velocity projectiles is an important process in the evolution of planets. Observations on planets and satellites with solid surfaces show that small impact craters are bowl-shaped and deep. Larger impact structures are shallow, they have overall flat interiors with several characteristic morphological elements, such as central ...

Impact cratering on porous asteroids
Icarus, 2003Abstract The increasing evidence that many or even most asteroids are rubble piles underscores the need to understand how porous structures respond to impact. Experiments are reported in which craters are formed in porous, crushable, silicate materials by impacts at 2 km/s. Target porosity ranged from 34 to 96%.

In this chapter, various experiments of impact cratering performed at a laboratory scale will be reviewed. As discussed in Chap. 5, natural planetary craters have a wide variety of shapes. Very high-speed and large-scale impact events must be reproduced to fully mimic the actual planetary craters, which is evidently impossible to accomplish.
