Journal ArticleDOI
Radio science observations with Mars Global Surveyor: Orbit insertion through one Mars year in mapping orbit
G. Leonard Tyler,Georges Balmino,David P. Hinson,William L. Sjogren,David E. Smith,Richard A. Simpson,Sami W. Asmar,Patricia Priest,Joseph D. Twicken +8 more
TL;DR: In this article, the authors used the 3.6-cm λ radio path of the Mars Global Surveyor (MGS) during periods of atmospheric occultation to estimate the vertical temperature-pressure structure T[p(r)] to accuracies at the surface of ΔT ≈ 0.4 K and Δp ≈ 2 Pa, and ∼10 K and ∼0.6 Pa at altitudes of 40-50 km; the error in radius is Δr ≈ 1 m at all levels.

Radio science investigations with Mars Observer
G. Leonard Tyler,Georges Balmino,David P. Hinson,William L. Sjogren,David E. Smith,Richard Woo,Sami W. Asmar,Michael J. Connally,Carole L. Hamilton,Richard A. Simpson +9 more
TL;DR: In this article, the authors used an improved radio transponder for two-way spacecraft tracking and a highly stable on-board oscillator for atmospheric occultation measurements for radio science investigations.
Journal ArticleDOI
Mars without Tharsis
Maria T. Zuber,David Smith +1 more
TL;DR: In this article, the authors presented a numerical technique to remove Tharsis from the Martian gravitational field by rotating the spherical harmonics back to the original coordinate system, in which the z-axis is coincident with the planetary rotation axis.

Mars: Change in Axial Tilt Due to Climate?
TL;DR: The average tilt of Mars' equator with respect to its orbital plane may have increased significantly over the age of the solar system, although Earth-like effective viscosities can account for virtually the entire present obliquity.
Journal ArticleDOI
Constraints on density models from radial moments: Applications to Earth, Moon, and Mars
TL;DR: In this article, an envelope of acceptable density models can be generated by scanning the transition depth from the center to the surface, and any monotonic model with specified mean density and mean inertial moment must lie within that envelope.

Some remarks on polar wandering
Peter Goldreich,Alar Toomre +1 more
TL;DR: For example, Earth polar wanderings attributed to rotation axis angular displacements generated by density redistribution on geologic time scale are attributed to density redistribution as discussed by the authors. But this is not always the case.
Journal ArticleDOI
Gravity and lithospheric stress on the terrestrial planets with reference to the Tharsis Region of Mars
TL;DR: In this article, improved stress models for isostatic compensation on Mars are obtained, based on fracture patterns on Mars and compared with the stresses predicted by the isostatics theory, and the computed stresses are in reasonable agreement with tectonic features on Mars.
Journal ArticleDOI
Tectonic patterns on a reoriented planet: Mars
TL;DR: In this article, Anderson et al. show that the positive mass anomaly associated with the Tharsis volcanoes may have reoriented Mars' lithosphere by as much as 25°.
Journal ArticleDOI
The moments of inertia of Mars
TL;DR: In this paper, the second degree gravity field of Mars is decomposed into a hydrostatic oblate spheroid and a non-hydrostatic prolate sphere with an equatorial axis of symmetry.

More about the moment of inertia of Mars
TL;DR: The most probable value of I/MR-squared is slightly less than 0.3650 as mentioned in this paper, which is the smallest value known to exist for any terrestrial planet in the solar system.
