[1] I develop several statistical indices of cratering on planetary surfaces based on Poissonian probability. These cratering formulas, being both analytic and probabilistic, have advantages over numerical or nonprobabilistic approaches in ease of calculation, clarity of interpretation, and evident flexibility. Specific indices developed include the fraction of a planet's surface expected to be cratered N occasions over a given time interval, expected uncertainty in crater coverage, the depth… Expand
Earth and Mars crater size frequency distribution and impact rates: Theoretical and observational analysis
A framework for the theoretical and analytical understanding of the impact crater-size frequency distribution is developed and applied to observed data from Mars and Earth. The analitical modelExpand

Abstract: One hundred and seventy-six craters on Earth are currently accepted as resulting from bolide impact; this list is growing at a rate of approximately two craters per year because of newExpand
The rate of small impacts on Earth
Asteroids tens to hundreds of meters in diameter constitute the most immediate impact hazard to human populations, yet the rate at which they arrive at Earth's surface is poorly known. AstronomicExpand
Terrestrial crater counts : Evidence of a two to four-fold increase in bolide flux at 125 Ma
(v2.4) Submitted to Earth,Planets and Space. October, 2007 Bounded before and after by long periods of stability, terrestrial crater counts document a rapid (25Ma duration) increase in craterExpand
Ejecta–megaregolith accumulation on planetesimals and large asteroids
– Megaregolith accumulation can have important thermal consequences for bodies that lose heat by conduction, as vacuous porosity of the kind observed in the lunar megaregolith lowers thermalExpand
Asteroid impact tsunami of 2880 March 16
SUMMARY NASA scientists have given a 1.1-km diameter asteroid (1950 DA) a 0.0 to 0.3 per cent probability of colliding with the Earth in the year 2880. This article examines a scenario where 1950Expand
[1] The strike of a cosmic body into a marine environment differs in several respects from impact on land. Oceans cover approximately 70% of the Earth's surface, implying not only that oceanic impactExpand
How will we recognize buried impact craters in terrestrial sedimentary basins
Criteria that are deemed critical for recognition of terrestrial impact craters include features from hand specimens such as shock metamorphic structures. Although these criteria have been selectedExpand
Hydrological modeling of the Martian crust with application to the pressurization of aquifers
[1] We develop a hydrological model of the Martian crust, including both ancient heavily cratered terrains and younger basaltic and sedimentary terrains. The porosity, permeability, andExpand
Impact Phenomena: In the Laboratory, on the Earth, and in the Solar System
Our planetary system exists for about 4.6 billions years. It has been formed from a primordial gaseous nebula composed mostly of hydrogen and helium. On the evolutionary path of the nebula the SunExpand


On the history of lunar impact cratering: The absolute time scale and the origin of planetesimals☆
Abstract From analyses of lunar crater counts, Canadian impact crater counts, and current meteoritic fluxes, combined with absolute datings keyed to Apollo 11 and Apollo 12 ages for the maria, it isExpand
Asteroid Impact Tsunami: A Probabilistic Hazard Assessment
Abstract We investigate the generation, propagation, and probabilistic hazard of tsunami spawned by oceanic asteroid impacts. The process first links the depth and diameter of parabolic impactExpand
Asteroid and comet flux in the neighborhood of the earth
Significant advances in the knowledge and understanding of the flux of large solid objects in the neighborhood of Earth have occurred. The best estimates of the collision rates with Earth ofExpand
Saturation and Equilibrium Conditions for Impact Cratering on the Lunar Surface: Criteria and Implications
A model based on first principles and laboratory results is presented for describing and evaluating long term effects of meteoritic impact against the lunar surface. The evolution of the crateredExpand
Assessment of Kinetic Energy of Meteoroids Detected by Satellite-Based Light Sensors☆
Abstract Radiation energies of bright flashes caused by disintegration of large meteoroids in the atmosphere have been measured using optical sensors on board geostationary satellites. Light curvesExpand
Impact Cratering: A Geologic Process
The mechanisms involved in the formation of impact craters are examined theoretically, reviewing the results of recent investigations. Topics addressed include crater morphology, stress waves inExpand
Observations of the lunar regolith and the Earth from the television camera on Surveyor 7
Surveyor 7, the last spacecraft of the Surveyor series, landed about 30 km north of the rim crest of Tycho, one of the most prominent and well-known features in the southern part of the moon. AboutExpand
Estimates of crater size for large-body impact: Gravity-scaling results
