Is Europa habitable?

08.08.2013
Defining the scientific goals of a NASA mission to explore Jupiter's moon

Europa, the ice-covered moon of the planet Jupiter, may be able to support life. NASA has commissioned a team of expert scientists to consider the science goals for a landed spacecraft mission to the surface of Europa, and to investigate the composition and geology of its icy shell and the potential for life within its interior ocean.


Astrobiology, led by Sherry L. Cady, Ph.D., and a prominent international editorial board comprised of esteemed scientists in the field, is the authoritative resource for the most up-to-date information and perspectives on exciting new research findings and discoveries emanating from interplanetary exploration and terrestrial field and laboratory research programs.

The NASA-appointed Science Definition Team outlines the main priorities of a future lander mission to Europa to study its potential habitability in an article in Astrobiology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Astrobiology website.

The article "Science Potential from a Europa Lander" presents the three main objectives of a future mission designed to land a robotic spacecraft on the surface of Europa and to investigate its potential to support life. NASA's Science Definition Team has clearly identified three main priorities: investigate the composition and chemistry of Europa's ocean; characterize the thickness, uniformity, and dynamics of its icy shell; and study the moon's human-scale surface geology. In addition, the NASA-appointed team describes the types of studies and payload of instruments recommended to achieve these objectives.

R.T. Pappalardo and a large group of coauthors contribute a broad range of knowledge and expertise and represent leading government and academic institutions, including NASA's Jet Propulsion Laboratory, managed by the California Institute of Technology (Pasadena), University of Colorado (Boulder), University of Texas at Austin, NASA's Goddard Space Flight Center (Greenbelt, MD), NASA's Ames Research Center (Moffett Field, CA), University of Iowa (Iowa City), NASA's Marshall Space Flight Center (Huntsville, AL), Southwest Research Institute (Boulder, CO), The Johns Hopkins University Applied Physics Laboratory (Laurel, MD), Arizona State University (Tempe), and Massachusetts Institute of Technology (Cambridge).

"Landing on Europa and touching its surface is a visionary goal of planetary science," says Robert Pappalardo, PhD of NASA's Jet Propulsion Laboratory. "This is a difficult technical challenge that is probably many years away. Understanding the key scientific questions to be addressed by a future Europa lander helps us to focus on the technologies required to get us there, and on the necessary data that might be attained by a precursor mission that could scout out landing sites. Europa is the most likely place in our solar system beyond Earth to have life today, and a landed mission would be the best way to search for signs of life."

"Landing on the surface of Europa is a key step in the astrobiological investigation of that world," says Christopher McKay, PhD, Senior Editor of Astrobiology and a scientist at NASA Ames Research Center, Moffett Field, CA. "The paper by Pappalardo et al. outlines the science that could be done by such a lander. The hope would be that surface materials, possibly near the linear crack features, include biomarkers carried up from the ocean."

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
