Chang’e-5 samples reveal two-billion-year-old volcanic activity on the Moon and its source characteristics

Abstract Returning humans to the Moon presents an unprecedented opportunity to determine the origin of volatiles stored in the permanently shaded regions (PSRs), which trace the history of lunar volcanic activity, solar wind surface chemistry, and volatile delivery to the Earth and Moon through impacts of comets, asteroids, and micrometeoroids. So far, the source of the volatiles sampled by the Lunar Crater Observation and Sensing Satellite (LCROSS) plume (1, 2) has remained undetermined. We show here that the source could not be volcanic outgassing and the composition is best explained by cometary impacts. Ruling out a volcanic source means that volatiles in the top 1–3 meters of the Cabeus PSR regolith may be younger than the latest volcanic outgassing event (~ 1 billion years ago; Gya) (3).

Tidal Heating

<p>Tidal dissipation is thought to power volcanism or cryovolcanism on a number of moons, most notably Io and Enceladus. The&#160;amount and distribution of tidal heating within the moon are however still misunderstood, and intricately related to surface&#160;observations like heat flow and distribution of volcanic activity. From an extensive benchmark between a set of numerical and&#160;semi-analytical models, we show that, in the presence of a subsurface (magma or&#160;water) ocean, librations (i.e. spin rate variations) along the orbit trigger additional deformation mechanisms, enhancing the amount of dissipation&#160;compared to traditional tidal dissipation (by at least 25% for Enceladus), and affecting the distribution of dissipation within the&#160;moon. We illustrate these mechanisms with numerous animations, and identify librational loading as the most relevant process.</p>

The Relationship

The determination of the relations, if any such exist, between volcanic activity and certain astronomical or meteorological phenomena, cannot fail to throw much light upon the vexed question of the solid or liquid condition of the earth’s interior. M. Perrey, as the result of his careful catalogue of earthquake phenomena, believed himself to have proved that these could be shown to have certain maxima and minima, which correspond with positions of the moon in relation to the earth and sun; there are many considerations which point to the conclusion that great and sudden changes in barometric pressure may be followed by outbursts of volcanic violence; and, finally, if the eruptions of volcanoes, as many geologists believe, are due to water percolating from the surface to a heated magma, rainfall must have no inconsiderable influence in determining the periods of their occurrence.

The Mean

The motion of an artificial satellite around the Moon is much more complicated than that around the Earth, since the shape of the Moon is a triaxial ellipsoid and the effect of the Earth on the motion is very important even for a very close satellite.The differential equations of motion of the satellite are written in canonical form of three degrees of freedom with time depending Hamiltonian. By eliminating short-periodic terms depending on the mean longitude of the satellite and by assuming that the Earth is moving on the lunar equator, however, the equations are reduced to those of two degrees of freedom with an energy integral.Since the mean motion of the Earth around the Moon is more rapid than the secular motion of the argument of pericentre of the satellite by a factor of one order, the terms depending on the longitude of the Earth can be eliminated, and the degree of freedom is reduced to one.Then the motion can be discussed by drawing equi-energy curves in two-dimensional space. According to these figures satellites with high inclination have large possibilities of falling down to the lunar surface even if the initial eccentricities are very small.The principal properties of the motion are not changed even if plausible values ofJ3andJ4of the Moon are included.This paper has been published in Publ. astr. Soc.Japan15, 301, 1963.
