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 …

An accurate assessment of the bulk chemical composition of Mars is fundamental to
understanding planetary accretion, differentiation, mantle evolution, the nature of the …

A planet's crust bears witness to the history of planetary formation and evolution, but for
Mars, no absolute measurement of crustal thickness has been available. Here, we …

Abstract The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat
Transport) mission landed in Elysium Planitia on Mars on 26 November 2018 and fully …

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

Martian valley networks have long been viewed as some of the best evidence of prolonged
surface water on Mars. Analysis from Viking data showed that valleys were primarily …

Constraints on the composition of Mars principally derive from chemical analyses of a set of
Martian meteorites that rely either on determinations of their refractory element abundances …

The ancient cratered terrain of the southern highlands of Mars is thought to hold clues to the
planet's early differentiation,, but until now no meteoritic regolith breccias have been …

Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

We report maps of the concentrations of H, Si, Cl, K, Fe, and Th as determined by the
Gamma Ray Spectrometer (GRS) on board the 2001 Mars Odyssey Mission for±∼ 45° …
