All Along the Fractures
The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter often takes images of Martian sand dunes to study the mobile soils. These images provide information about erosion and movement of surface material, about wind and weather patterns, even about the soil grains and grain sizes. However, looking past the dunes, these images also reveal the nature of the substrate beneath.
Within the spaces between the dunes, a resistant and highly fractured surface is revealed. The fractured ground is resistant to erosion by the wind, and suggests the material is bedrock that is now shattered by a history of bending stresses or temperature changes, such as cooling, for example.
Alternately, the surface may be a sedimentary layer that was once wet and shrunk and fractured as it dried, like gigantic mud cracks. In either case, the relative small and indistinct fractures have trapped the dark dune sand marching overhead. Now the fractures have become quite distinct, allowing us to examine the orientation and spacing of the fractures to learn more about the processes that formed them.
This view is one image product from HiRISE observation ESP_042223_1890, taken July 30, 2015, at 2:33 p.m. local Mars time, 8.719 degrees north latitude, 67.347 degrees east longitude.
HiRISE is one of six instruments on the Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the orbiter and collaborates with JPL to operate it.

The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter acquired this closeup image of a light-toned deposit in Aureum Chaos, a 368 kilometer (229 mile) wide area in the eastern part of Valles Marineris, on Jan. 15, 2015, at 2:51 p.m. local Mars time.
The objective of this observation is to examine a light-toned deposit in a region of what is called “chaotic terrain.” There are indications of layers in the image. Some shapes suggest erosion by a fluid moving north and south. The top of the light-toned deposit appears rough, in contrast to the smoothness of its surroundings.

el dispensador dice:
amores,
locuras,
odios y puentes que se fracturan...
intenciones que se ocultan,
mentiras inmaduras,
traiciones y armaduras,
caballeros que no dudan,
el oro salva,
el amor no escuda,
depredación,
huellas que se borran,
mientras las sombras se nublan...
ningún Sol,
muchas brumas,
las arenas cambian,
para mostrarse como dunas,
los humanos creen ver algo,
pero las existencias perduran,
los urgenciados sólo se apuran,
atrapados en mezquindades que empujan,
demasiadas miserias humanas que producen fracturas...
las eternidades presentes,
cambian sus espesuras,
se muestran de una forma,
pero la dimensión verdadera... es la oculta...
hay algo que llama,
hay algo que nadie escucha...
los que hablan con silencios,
saben de distancias que completan lunas...
lo que se rompe por desidia,
no se compone con arcilla...
cuidado con lo que sigue,
la eternidad empecinada no se consigue...
si no te liberas del ego,
te pesa el aura...
y ella se consume,
como fuego que se resume,
en el cinismo que vende,
donde nada se une...
donde todo hace que el futuro se esfume...
no te asomes... donde no te llamen...
donde no veas lumbre...
puede que te sorprenda,
pero allí... ya estuve.
OCTUBRE 07, 2015.-
amor que se miente... siempre se descubre.
