Mars Science Laboratory Mission Status Report
PASADENA, Calif. – After imaging during the holidays, NASA’s Mars rover Curiosity resumed driving Jan. 3 and pulled within arm’s reach of a sinuous rock feature called “Snake River.”
Snake River is a thin curving line of darker rock cutting through flatter rocks and jutting above sand. Curiosity’s science team plans to get a closer look at it before proceeding to other nearby rocks. (more…)
Warmer air temperatures since the 1980s may explain significant increases in zinc and other metal concentrations of ecological concern in a Rocky Mountain watershed, reports a new study led by the U.S. Geological Survey and the University of Colorado Boulder.
Rising concentrations of zinc and other metals in the upper Snake River just west of the Continental Divide near Keystone, Colo., may be the result of falling water tables, melting permafrost and accelerating mineral weathering rates, all driven by warmer air temperatures in the watershed. Researchers observed a fourfold increase in dissolved zinc over the last 30 years during the month of September. (more…)
