Cometary collisions on the Moon and Mercury

  author={Peter H. Schultz and Leonard J. Srnka},
Unusual swirl patterns of bright and dark material on the Moon and Mercury are proposed to be remnants of collisions with gas/dust-rich regions within a cometary coma. This interpretation provides important new clues for understanding cometary fine structure, impact effects of low-density material, and the origin of certain pronounced magnetic anomalies. 
Reiner Gamma is the only near side example of the elusive Lunar Swirl features. There exist only three other known examples, two on the moons far side, and another on Mercury. The origin of these
Lunar magnetism, polar displacements and primeval satellites in the Earth–Moon system
The discovery that rocks of the lunar crust possess remanent magnetism is a surprising result in view of the fact that the present Moon does not exhibit a magnetic field, nor was there once evidence
Lunar magnetism—a retrospective view of the Apollo sample magnetic studies
Abstract The rock magnetism and paleomagnetism of the Apollo samples is reviewed and evidence is presented for an era of strong lunar magnetic fields between 3.9 and 3.6 By. The most plausible model
Swirls on the Moon and Mercury: meteoroid swarm encounters as a formation mechanism
We show that plowing of the lunar and mercurian regoliths by dense meteoroid swarms (the remnants of degassed comet nuclei) can be considered as the most probable mechanism of swirl formation.
Some fluid dynamic problems in the studies of planetary collisions with cometary comas
The flow field in a cometary coma varies from free molecular flow to transition flow and finally to continuum flow. General discussions of these flow regimes with two-phase effects are given. Some
Water Group Exospheres and Surface Interactions on the Moon, Mercury, and Ceres
Water ice, abundant in the outer solar system, is volatile in the inner solar system. On the largest airless bodies of the inner solar system (Mercury, the Moon, Ceres), water can be an exospheric
A preliminary global map of the vector lunar crustal magnetic field based on Lunar Prospector magnetometer data
Processing and mapping of the Lunar Prospector magnetometer data is supported by the NASA Discovery Data Analysis Program.
Correlation of a strong lunar magnetic anomaly with a high‐albedo region of the Descartes mountains
[1] Mapping and model simulations of Lunar Prospector magnetometer measurements show that the source of the strongest known magnetic anomaly on the lunar near side (42 nanoTeslas at 18.6 km altitude)
Magnetism of the Moon - a lunar core dynamo or impact magnetization?
Surface and satellite observations of lunar crustal magnetization and the remanent magnetization of the lunar samples returned by the Apollo missions of 1969–72 provide evidence for past magnetic
Mapping of crustal magnetic anomalies on the lunar near side by the Lunar Prospector electron reflectometer
Lunar Prospector (LP) electron reflectometer measurements show that surface fields are generally weak in the large mare basalt filled impact basins on the near side but are stronger over highland


Cometary impact and the magnetization of the Moon
Abstract Collisions of comets with planetary bodies are capable of impressing patterns of magnetization onto them that match those observed for the Moon and possibly for Mercury. The ambient solar
Magnetisation of comets
THE presence of magnetic fields in the plasma tails of comets is suggested by the rayed structures and helical features observed in them1. According to the present picture of the solar wind-comet
The Ancient Lunar Core Dynamo
Lunar paleomagnetism provides evidence for the existence of an ancient lunar magnetic field generated in an iron core, and it is suggested that superheavy elements were present in the early moon.
The origin of lunar palaeomagnetism
THE new determination of magnetic field anomalies over part of the Moon's surface from Apollo 15 and 16 subsatellite magnetometer data has recently been interpreted1 in terms of magnetised areas of
Simulation of cometary magnetic tails
In order to simulate a cometary tail in a laboratory the flow of hydrogen collisionless supersonic plasma with the magnetic field frozen in was used. The wax ball served as a model of the cometary
Correlation of lunar far-side magnetized regions with ringed impact basins
By the method of electron reflection, we have identified seven well-defined magnetized regions in the equatorial belt of the lunar far side sampled by the Apollo 16 Particles and Fields subsatellite.

IUE observations of Solar System objects
During the scientific commissioning phase of IUE several spectra were acquired from objects residing in the Solar System. The activities focused on testing numerous parameters which would indicate
The Moon: Sources of the Crustal Magnetic Anomalies
Previously unmapped Apollo 16 subsatellite magnetometer data collected at low altitudes over the lunar near side are presented, implying that magnetization of lunar crustal materials must have continued for a period exceeding 1 billion years.
On the Theory of Comet Tails
According to Biermann's theory the repulsive force in comet tails is due to a corpuscular radiation from the sun. It is shown that some of the difficulties of this theory can be overcome if the
