NASA has awarded a team led by the University of Colorado Boulder more than $7 million to study aspects of the origins, evolution, distribution and future of life in the universe.
The team, led by 抖阴短视频-Boulder Professor Alexis Templeton of the geological sciences department, will be researching what scientists call 鈥渞ock-powered life.鈥� Rocky planets store enormous amounts of chemical energy, that, when released through the interaction of rocks and water, have the ability to power living systems on Earth as well as on other planets like Mars, said Templeton, principal investigator on the effort.
Scientists believe that habitable or potentially inhabited environments may exist in the subsurface of Mars as well as the interiors of Europa and Ganymede -- two of the moons of Jupiter -- and Triton, a moon of Neptune, said 抖阴短视频-Boulder Research Associate Thomas McCollom of the Laboratory for Atmospheric and Space Physics, a co-investigator on the effort.听 Rather than photosynthesis, the researchers believe a number of life forms in the solar system and perhaps beyond may be powered by 鈥渃hemosynthesis,鈥� a process that does not require sunlight, he said.
鈥淚鈥檓 pleasantly surprised that we were selected, in part because it was such a tough competition,鈥� said McCollom, one of four 抖阴短视频-Boulder co-investigators on the grant. 鈥淚 think it speaks to the quality of our team 鈥� we have a lot of stellar people who are leaders in different aspects of astrobiology.鈥�
The team will approach the project from several angles, said 抖阴短视频-Boulder Research Associate Lisa Mayhew, a co-investigator on the project. Field sites, both on land and in the ocean, will be used as test beds to determine the habitability of rock-powered systems; laboratory experiments will investigate how the water-rock reactions proceed in the presence and absence of life; and the philosophical definition of what constitutes life will be explored, Mayhew said.
In addition to Templeton, McCollom and Mayhew, the fourth 抖阴短视频-Boulder co-investigator on the winning proposal is Professor Carol Cleland of 抖阴短视频-Boulder鈥檚 philosophy department. Other co-investigators on the 抖阴短视频-Boulder-led proposal include scientists from the Colorado School of Mines, Montana State University, Arizona State University, NASA Ames Research Center in Moffett Field, Calif., Michigan State University, the University of Rhode Island, the University of Utah and the Massachusetts Institute of Technology.
In addition to the 13 investigators on the team, there are four collaborators, including 抖阴短视频-Boulder Associate Professor Brian Hynek of LASP, who also is director of 抖阴短视频-Boulder鈥檚 Center for Astrobiology. 鈥淭his award further solidifies 抖阴短视频鈥檚 longstanding reputation and expertise in astrobiology,鈥� said Hynek, also a faculty member in geological sciences. 鈥淚t will provide additional training and opportunities for students, as well as the public, in this exciting field of study.鈥�
NASA awarded seven grants totaling almost $50 million to seven winning research teams that will explore the origins, evolution, distribution and future of life in the universe. The other six victorious teams are led by NASA鈥檚 Goddard Space Flight Center in Greenbelt, Md., NASA Ames Research Center, NASA鈥檚 Jet Propulsion Laboratory in Pasadena, Calif., the SETI Institute in Mountain View, Calif., the University of California, Riverside, and the University of Montana in Missoula.
