Abstract The Heat Flow and Physical Properties Package HP 3 for the InSight mission will
attempt the first measurement of the planetary heat flow of Mars. The data will be taken at the …

▪ Abstract The bulk of the∼ 50-km-thick Martian crust formed at∼ 4.5 Gyr BP, perhaps from a
magma ocean. This crust is probably a basaltic andesite or andesite and is enriched in …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

Mars accumulated and differentiated into crust, mantle and core within a few tens of millions
of years of Solar System formation. Formation of Hellas, which has been adopted as the …

With 2years of tracking data collection from the MRO spacecraft, there is noticeable
improvement in the high frequency portion of the spherical harmonic Mars gravity field. The …

Venus is Earth's twin in size and radiogenic heat budget, yet it remains unclear how Venus
loses its heat absent plate tectonics. Most Venusian stagnant-lid models predict a thick …

We present a spherical harmonic solution of the static gravity field of Mars to degree and
order 120, GMM-3, that has been calculated using the Deep Space Network tracking data of …

Enceladus's gravity and shape have been explained in terms of a thick isostatic ice shell
floating on a global ocean, in contradiction of the thin shell implied by librations. Here we …
