NASA Spacecraft Detects Buried Glaciers on Mars

PASADENA, Calif.-- NASA's Mars Reconnaissance Orbiter has revealed vast Martian glaciers of water ice under protective blankets of rocky debris at much lower latitudes than any ice previously identified on the Red Planet.
Scientists analyzed data from the spacecraft's ground-penetrating radar and report in the Nov. 21 issue of the journal Science that buried glaciers extend for dozens of miles from the edges of mountains or cliffs. A layer of rocky debris blanketing the ice may have preserved the underground glaciers as remnants from an ice sheet that covered middle latitudes during a past ice age. This discovery is similar to massive ice glaciers that have been detected under rocky coverings in Antarctica.
"Altogether, these glaciers almost certainly represent the largest reservoir of water ice on Mars that is not in the polar caps," said John W. Holt of the University of Texas at Austin, who is lead author of the report. "Just one of the features we examined is three times larger than the city of Los Angeles and up to half a mile thick. And there are many more. In addition to their scientific value, they could be a source of water to support future exploration of Mars."…

 

El satélite Orbiter descubrió con sus instrumentos de radar que bajo las rocas y escombros se esconden tan grandes depósitos de agua congelado con cientos a miles de metros de grosor. Tres veces el Tamaño de la ciudad de los Angeles y casi mil metro de profundidad se calcula en un solo lugar analizado. Cada vez se descubre mas y cada vez el descubrimiento es tan significante hacia la posibilidad de albergar vida en nuestro planeta hermano.

Yo digo, la vida tiene mucha pata. Camina o no, piensa o no,pero vida en sus inimaginables formas esta ahí!
