  Chryse Planitia - Wikipedia, the free encyclopedia
Chryse Planitia is a smooth circular plain in the northern equatorial region of Mars close to the Tharsis region.
Chryse Planitia shows evidence of water erosion in the past, and is the bottom end for many outflow channels from the southern highlands as well as from Valles Marineris and the flanks of the Tharsis bulge.
It has been theorized that the Chryse basin may have contained a large lake or an ocean during the Hesperian or early Amazonian periods since all of the large outflow channels entering it end at the same elevation, at which some surface features suggest an ancient shoreline may be present.

This story is one all people should know, for in an age in which we have yet to set a human foot on Mars, the legacy of this manmade mechanical explorer should stand with those of Neil Armstrong and Sputnik.
In 1877, Schiaparelli observed with the aid of a telescope a bright region on Mars and named it Chryse after a golden land rumored in ancient times to be located east of the Indian Ocean.
Chryse Planitia was chosen as the landing site, not only because from the Viking I observations it appeared to be very smooth, but also because those same pictures showed large channels running into the desert plains which seemed to indicate that large amounts of water had been emptied into this region.

 PSR Discoveries: Outflow Channels in Chryse Planitia, Mars
MOLA data show that Chryse Planitia is not a closed basin, as thought previously, but rather a low area with a gentle regional slope to the north-northeast.
The absence of a topographic low within Chryse Planitia, and lack of a barrier between the channel mouths and the northern lowlands, suggests that channels emptied and spread out beyond Chryse into the North Polar basin.
Some of the channels continue out of Chryse Planitia for hundreds of kilometers into the North Polar basin, but their patterns are subdued and very different once past their recognized termini.

 Chryse - Wikipedia, the free encyclopedia
In Greek mythology, Chryse (Greek: Χρύση, Khrýsē) was a lover of Ares and mother of Phlegyas.
Chryse (Greek: Χρύση, Khrýsē) is also an island in the Mediterranean where, in Greek mythology, Philoctetes was bitten by a snake.
Chryse is also the name of a town mentioned in The Iliad, from which Agamemnon took Chryseis.

Teardrop-shaped "islands" are shown at the mouth of Ares Vallis near the southern boundary of Chryse Planitia.
Flow was from the south and apparently diverged around obstacles such as craters and low hills to form a sharp prow upstream and an elongate tail downstream.
The west side of Chryse Planitia has been extensively sculpted by flow from Maja Vallis, which is situated just to the left of this mosaic.

High-resolution (1:500,000-scale) geologic mapping of a 300 -km-wide and 1500-km-long strip, or geotraverse, across the transition from the Xanthe Terra cratered highlands to the Chryse Planitia lowlands encompasses an area on the margin of the Chryse Basin unaffected by outflow channels.
Erosion of the moat-filling deposit along the outer margins of the Chryse basin accounts for the streamlined tables formed during outflow channeling throughout the margins of Chryse Planitia.
The geology of the central basin interior, where the Viking 1 Lander is located, is consistent with the presence of fluvial sediments derived from both the adjacent highlands and remobilized from the marginal moat-filling unit, and deposited near the termini of the Maja and Kasei Valles outflow channels.

 Pathfinder's Port of Call
The landing site was in a region called Chryse Planitia, which means Plain of Gold.
Chryse Planitia is a wind-whipped flood plain, thought to have been formed when massive flows of water, enough to fill all five of Earth's Great Lakes, rushed over the northern lowlands a few billion years ago.
The closest low-elevation, flat area lies on Chryse Planitia.

The Viking 1 lander set down on Chryse Planitia, a flood plain at 23 degrees north latitude.
"It was a very different environment from the flood plains of Chryse." The weather at Utopia Planitia was different -- a result of its more northern latitude, there were curious pedestals that scientists thought might be small volcanoes, and the terrain was littered with the ejecta of the nearby impact crater.
At its northern latitude in Utopia Planitia, Viking 2 frequently saw a thin layer of frost (water ice) dusting the terrain.

The density of impact craters in the 100 m to 2 km range is close to half the average for lunar maria.
No traces can be seen of the large channels that scour the surface of Chryse Planitia 200 km to the southwest and trend toward the site.
The plains appear volcanic, and the absence of fluvial features suggests either that the channels did not reach as far as the site or that fluvial features are covered by younger deposits.

Chryse Planitia may once have been an ocean.
Dr Coleman says his latest study shows that nowhere is the evidence for vast quantities of running water clearer than the outflow channels of Chryse Planitia.
Consider the associated Kasei Valles, he suggests, it is a system of intertwined flood-carved channels more than 2,000 km long that begins in near the equator in Echus Chasma and ends in Chryse Planitia.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an impact crater in Chryse Planitia, not too far from the Viking 1 lander site, that to seems to resemble a bug-eyed head.
The two odd depressions at the north end of the crater (the "eyes") may have formed by wind or water erosion.
This region has been modified by both processes, with water action occurring in the distant past via floods that poured across western Chryse Planitia from Maja Valles, and wind action common occurrence in more recent history.

 BBC NEWS | Science/Nature | Mars was a water world
Neil Coleman has studied some of the most dramatic and significant scenery on Mars: the enormous outflow channels of Chryse Planitia.
Neill Coleman's work, published in the Journal of Geophysical Research, is, he believes, conclusive evidence that water, not carbon dioxide, is responsible for the features seen on the planet's surface.
He suggests it is a system of intertwined flood-carved channels more than 2,000 kilometres long that begins in near the equator in Echus Chasma and ends in Chryse Planitia.

These represent the 'highlands' (Ascraeus Mons), the 'lowlands' (Hellas Planitia), and at the mouth of the large canyon structure Valles Marineris (Chryse Planitia).
Although no water was found within the first 100 meters of the surface, indications of subsurface water were found after 100 meters and materials with significantly higher water content (.05% by mass) were found after 300 meters.
In the Chryse Planitia region this water content was found somewhat closer to the surface (200 meters) while in the Hellas Planitia region, no significant water was found to the depth of 300 meters.

The site is also at a low enough elevation to allow the parachutes sufficient atmosphere to brake the lander’s descent, has few steep slopes down which the tiny probe may have to bounce as it lands, and doesn’t seem to be too dusty.
Further studies, however, showed that the probe would be unable to function properly at these sites because their latitudes make them too cold in early spring.

At the resolution of the orbiter images, the surface had appeared featureless apart from impact craters and wrinkle ridges---there was little, indeed, to distinguish it from one of the wide gray plains of the Moon.
Unlike the rather varied rock forms of Chryse, Utopia's rocks proved to be larger on average and more evenly distributed across the surface, with no bedrock outcrops or large drifts, and this created a singularly monotonous appearance.
Whereas the Chryse site consisted of gently rolling plains, Utopia proved to be remarkably flat, presumably because of its proximity to the 90-kilometer impact crater, Mie, whose rim lay 170 kilometers east of the landing site.
