NASA has awarded five-year grants totaling almost $40 million to five research teams to study the origin, evolution, distribution, and future of life in the universe. The newly selected teams are from the University of Washington; Massachusetts Institute of Technology; University of Wisconsin, Madison; University of Illinois, Urbana-Champaign; and University of Southern California. Average funding to the teams is almost $8 million each. The interdisciplinary teams will become members of...

Arctic Bacteria Help In The Search To Find Life On Europa
2012-05-31 02:53:51

In a fjord in Canada scientists have found a landscape similar to one of Jupiter's icy moons: Europa. It consists of a frozen and sulphurous environment, where sulphur associated with Arctic bacteria offer clues for the upcoming missions in the search for traces of life on Europa. It is not easy to find a place on Earth where ice and sulphur come together, supposedly like on Europa, Jupiter's moon. Nonetheless, this place has been located at Borup Fjord Pass in the Canadian High Arctic....

Biologists have been unable to agree on a definition of the complex phenomenon known as "life." In a special collection of essays in Astrobiology, a peer-reviewed journal from Mary Ann Liebert, Inc., leaders in the fields of philosophy, science, and molecular evolution present a variety of perspectives on defining life. Tables of content and a free sample issue are available online. Why is a definition of life so important yet so elusive? As David Deamer, Guest Editor and Research Professor...

U.S. and British scientists have developed a cleaning protocol for space hardware that could be used on missions to other planets. The protocol was developed as part of a project to investigate life that exists in extreme Arctic environments, which are the closest analogue on Earth to the surface of Mars. The protocol, developed and tested by scientists at the University of Leeds and the National Aeronautics and Space Administration, deals with the dilemma known as forward contamination --...

Data from the Mars Reconnaissance Orbiter (MRO) suggest the discovery of ancient springs in the Vernal Crater, sites where life forms may have evolved on Mars, according to a report in Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Hot springs have great astrobiological significance, as the closest relatives of many of the most ancient organisms on Earth can thrive in and around hydrothermal springs. If life forms have ever been present on Mars, hot spring deposits...

SAN FRANCISCO, Calif. -- Hunting for traces of life on Mars calls for two radically different strategies, says Arizona State University professor Jack Farmer. Of the two, he says, with today's exploration technology we can most easily look for evidence for past life, preserved as fossil "biosignatures" in old rocks. Farmer is a professor of geological sciences in ASU's School of Earth and Space Exploration, where he heads the astrobiology program. He is reporting on his work today (Feb. 16)...

High in the Arctic, just below Earth's north polar ice cap, a collaboration of nearly two dozen biologists, geologists, and engineers have embarked on an expedition to Mars. The scientists and researchers are spending two and a half weeks at the Svalbard archipelago in the Arctic Ocean north of Norway. The goal of this annual expedition, called the Arctic Mars Analogue Svalbard Expedition (AMASE), is to characterize the geology, geophysical features, biosignatures, and possible life forms of...
