New Research Reveals Europa's Mystery Dark Material Could Be Sea Salt

on May 27, 2015 - 3:30pm
AGU/NASA News:
 
WASHINGTON, D.C.  New laboratory experiments suggest the dark material coating some geological features of Jupiter's moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation.
The presence of sea salt on Europa's surface suggests the ocean is interacting with its rocky seaflooran important consideration in determining whether the icy moon could support life.
 
The new study has been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, and is available online.

Mars Rover’s ChemCam Instrument Gets Sharper Vision

on May 27, 2015 - 8:46am

Yellowjacket is the first rock targeted by the NASA Mars Rover’s ChemCam device after checkout of the auto-focus repair. It is a layered sedimentary rock. The laser analysis yielded a composition very close to that of Mars soil and unlike the lakebed sedimentary compositions observed at lower elevations and earlier in the mission. The soil-like composition may indicate that these rocks formed from sediment transported by wind, rather than by water. The ChemCam image also shows millimeter-size spherules of unknown origin, not seen in most earlier sedimentary rocks.

WIPP: Work Begins On Interim Ventilation System

WIPP News:
 
Recovery operations at the WIPP facility continue to move forward with work beginning on installation of the interim ventilation system.
 
This system will increase the overall amount of airflow in the underground facility from the 60,000 cubic feet per minute (CFM) available under the current configuration up to 114,000 CFM. Following the radiological event of February 2014, all air exiting the WIPP underground passes through High Efficiency Particulate Air (HEPA) filters prior to being released into the environment.
 
As a result, the amount of air that can be used to
