News From Mars
A NASA probe has spotted hundreds of small surface fractures near Mars' equator that may have acted as underground natural plumbing to channel groundwater billions of years ago.
Geologists compare the fractures in the sandstone rock deposits on Mars to features called deformation bands on Earth, which can arise from the influence of groundwater in the underground bedrock. The bands and faults have strong influences on groundwater movement on Earth, and seem to have played the same role on Mars. Other research has examined how surface water from rain or snow shaped the planet surface, but many agree that groundwater has an equally important influence.
"Groundwater often flows along fractures such as these, and knowing that these are deformation bands helps us understand how the underground plumbing may have worked within these layered deposits," said Chris Okubo, a geologist with the U.S. Geological Survey in Flagstaff, Ariz. who headed up a new study of the Martian fractures.
The observations, made by NASA's Mars Reconnaissance Orbiter (MRO), showed how water has already changed the color and texture of the Martian sandstone along the fractures. Okubo's report on the finding is detailed online this month in the journal Geological Society of America Bulletin.
"This study provides a picture of not just surface water erosion, but true groundwater effects widely distributed over the planet," said Suzanne Smrekar, deputy project scientist for MRO at NASA's Jet Propulsion Laboratory in Pasadena, Calif., who was not part of the study. "Groundwater movement has important implications for how the temperature and chemistry of the crust have changed over time, which in turn affects the potential for habitats for past life."
Okubo and his study coauthors looked to similar patterns in Utah sandstones on Earth, where fractures are typically a few yards wide and up to several miles long. Such cracks reveal themselves as the rock layers on top erode away.

Terraforming Mars

A picture by the Martian Terra forming command of the early stages of the greening of Mars.
The Terra-forming of Mars by the Martian Caliphate was the largest engineering project ever accomplished in the solar system and brought about a huge expansion in the solar systems economy. Many historians note all of mankind was moved by this achievement to stride to do better. And while there was a some protest by the Red Mars movement who demanded that humanity leave Mars unchanged, calling for recognition of mars natural beauty; they were a very small minority.
