NASA research shows Jupiter’s moon Europa may have Chemistry Needed for Life

 

Written by Jia-Rui C. Cook
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new paper led by a NASA researcher shows that hydrogen peroxide is abundant across much of the surface of Jupiter’s moon Europa. The authors argue that if the peroxide on the surface of Europa mixes into the ocean below, it could be an important energy supply for simple forms of life, if life were to exist there.

The paper was published online recently in the Astrophysical Journal Letters.

The bright white and bluish part of Europa's surface is composed mostly of water ice, with very few non-ice materials. (Image credit: NASA/JPL/University of Arizona)

NASA Flies Robotic Lander Prototype to New Heights

NASA Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – NASA successfully completed the final flight in a series of tests of a new robotic lander prototype at the Redstone Test Center’s propulsion test facility on the U.S. Army Redstone Arsenal in Huntsville, AL.

Data from this test series will aid in the design and development of a new generation of small, smart, versatile robotic landers capable of performing science and exploration research on the surface of the moon or other airless bodies in the solar system, such as asteroids or the planet Mercury.

Since early October, the Robotic Lander Development Project at NASA’s Marshall Space Flight Center in Huntsville has subjected the lander prototype to a series of more complex outdoor flight tests maneuvers.

NASA engineers successfully integrated and completed system testing on a new robotic lander recently at Teledyne Brown Engineering’s facility in Huntsville in support of the Robotic Lunar Lander Project at NASA's Marshall Space Flight Center in Huntsville, AL. The lander prototype will aid NASA’s development of a new generation of small, smart, versatile landers for airless bodies such as the moon and asteroids. (Credit: NASA/David Higginbotham)

New NASA Missions to Investigate How Mars Turned Hostile

 

Written by Bill Steigerwald
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Maybe because it appears as a speck of blood in the sky, the planet Mars was named after the Roman god of war. From the point of view of life as we know it, that’s appropriate.

The Martian surface is incredibly hostile for life. The Red Planet’s thin atmosphere does little to shield the ground against radiation from the Sun and space. Harsh chemicals, like hydrogen peroxide, permeate the soil.

Liquid water, a necessity for life, can’t exist for very long here—any that does not quickly evaporate in the diffuse air will soon freeze out in subzero temperatures common over much of the planet.
