TLDR
The Mars Global Surveyor (MGS) spacecraft achieved a 45-hour elliptical orbit at Mars on 11 September 1997 after an 11-month cruise from Earth.Abstract:
The Mars Global Surveyor (MGS) spacecraft achieved a 45-hour elliptical orbit at Mars on 11 September 1997 after an 11-month cruise from Earth. The mission is acquiring high-quality global observations of the martian surface and atmosphere and of its magnetic and gravitational fields. These observations will continue for one martian year.read more

TL;DR: The Mars Orbiter Laser Altimeter (MOLA) has been used to measure the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of volatile and dust clouds as mentioned in this paper.

Evidence for recent groundwater seepage and surface runoff on Mars
TL;DR: Gullies within the walls of a very small number of impact craters, south polar pits, and two of the larger martian valleys display geomorphic features that can be explained by processes associated with groundwater seepage and surface runoff.

TL;DR: Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars, which includes the low northern hemisphere, the Tharsis province, and the Hellas impact basin.

Mars Global Surveyor Mars Orbiter Camera: Interplanetary cruise through primary mission
TL;DR: More than three years of high-resolution (1.5-20 m/pixel) photographic observations of the surface of Mars have dramatically changed our view of that planet as mentioned in this paper, and some of the most important observations and interpretations derived therefrom are that much of Mars, at least to depths of several kilometers, is layered; substantial portions of the planet has experienced burial and subsequent exhumation; layered and massive units, many kilometers thick, appear to reflect an ancient period of large-scale erosion and deposition within what are now the ancient heavily cratered regions of Mars; and

TL;DR: The strength of the lithosphere beneath the ancient southern highlands suggests that the northern hemisphere was a locus of high heat flow early in martian history and the thickness of the elastic lithosphere increases with time of loading in the northern plains and Tharsis.

TL;DR: Throughout the MGS mission, thermospheric density bulges have been detected on opposite sides of the planet near 90 degreesE and 90 degreesW, in the vicinity of maximum terrain heights, suggesting a wave 2 pattern may be caused by topographically-forced planetary waves propagating up from the lower atmosphere.

TL;DR: The first 18 tracks of laser altimeter data across the northern hemisphere of Mars from the Mars Global Surveyor spacecraft show that the planet at latitudes north of 50 degrees is exceptionally flat; slopes and surface roughness increase toward the equator.

Foreword [to special section on Mars Observer]
TL;DR: The Mars Observer mission as discussed by the authors provides a low, Sun-synchronous, polar orbit about the planet from which the entire surface and atmosphere can be repetitively observed and mapped by remote sensing instruments for an entire Mars year.
