AUSTIN, Texas — In a finding of relevance to the search for life in our solar system, researchers at The University of Texas at Austin’s Institute for Geophysics, the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have shown that the subsurface ocean on Jupiter’s moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.
Scientists believe Europa is one of the planetary bodies in our solar system most likely to have conditions that could sustain life, an idea reinforced by magnetometer readings from the Galileo spacecraft detecting signs of a salty, global ocean below the moon’s icy shell. (more…)
AUSTIN, Texas — Scientists at the University of Texas at Austin’s Institute for Geophysics helped develop a blueprint for a possible future NASA lander mission to Europa, an icy moon of Jupiter that has a global ocean covered by an ice shell. Europa’s large reservoir of liquid water has long enchanted planetary scientists with the possibility of harboring life. Many experts believe it to be the most likely place in our solar system besides Earth to host life today. The proposed mission is designed to assess the moon’s habitability by studying its surface composition, ice shell, ocean and geology.
Don Blankenship, senior research scientist at the institute, is part of the science definition team commissioned by NASA to draft the report, which appears in the August 2013 issue of Astrobiology. Blankenship and two colleagues — Krista Soderlund, postdoctoral fellow at the institute; and Britney Schmidt, formerly a postdoctoral fellow at the institute, now assistant professor at the Georgia Institute of Technology — developed a part of the mission scenario that would use sound waves to study the moon’s icy shell, deep ocean and possible shallow lakes.

PASADENA, Calif. — Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.
The data suggest there is significant exchange between Europa’s icy shell and the ocean beneath. This information could bolster arguments that Europa’s global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings are published in the scientific journal Nature.(more…)
