The roadmap embodies the efforts of more than 200 scientists and technologists, including NASA employees, academic scientists whose research is partially funded by NASA grants, and many members of the broader community who have no formal association with NASA. Fundamental Questions Astrobiology addresses three basic questions that have been asked in various ways for generations. How does life begin and evolve?

Moon to Mars Five Year Retrospective: Mars Pathfinder by Astrobiology Magazine Staffwriter Mars Posted: 09/27/02 Summary: Five years ago today, on September 27, 1997, the Mars Pathfinder lander began to tally up its remarkable mission history. The excitement was non-stop beginning only 3 minutes after landing, when the first signals of success came back to rapt Earth-bound listeners. Five Year Retrospective: Mars Pathfinder Five years ago today, on September 27, 1997, NASA and the Jet Propulsion Laboratory began to lose communication and battery power to the Mars Pathfinder mission, ending its highly successful exploration. Artist conception of Pathfinder's dramatic airbag landing Credit: NASA. The Pathfinder lander, formally named the Carl Sagan Memorial Station following its successful touchdown, landed on July 4, 1997 with its Rover, called Sojourner. Pathfinder returned 2.6 gigabits (2.6 billion bits) of data and 16,000 tantalizing pictures of the Martian landscape, including 550 close-up images from the rover. Assisted by an 11- meter (36-foot) diameter parachute, the spacecraft descended to the surface of Mars and landed, using airbags for the first time to cushion the impact.

Feedback I am a graduate student at Michigan State University in the experimental evolution laboratory of Richard Lenski . Currently, I study the evolution of stress tolerance in microbes , particularly the tolerance of dessication and UV-radiation. My study system involves repeatedly exposing the model bacterium Escherichia coli to desiccation and radiation stresses in long-term evolution experiments (i.e., This system allows me to examine de novo evolution of these stress tolerances. Previously, I studied microbialite-forming cyanobacteria and deep subsurface bacteria. My interests include the ecology, evolution and stoichiometry of microbes, geomicrobiology and astrobiology. My ultimate goal is to synthesize my previous training in ecology and my current training in evolution to better understand microbial systems. (Current as of October 2010) © 2010 Brian D. Wade

These unapproved articles are subject to edit intro Astrobiology is the study of the origins evolution , distribution, and future of life in the universe . Astrobiology, the study of life as a planetary phenomenon, aims to understand the fundamental nature of life on earth and the possibility of life elsewhere. To achieve this goal, astrobiologists have initiated unprecedented communication between the disciplines of astronomy biology chemistry , and geology . Astrobiology addresses three fundamental questions: How does life begin and evolve? Is there life beyond Earth and how can we detect it? What is the future of life on Earth and in the universe? Astrobiology requires fundamental concepts of life and habitable environments that will help scientists to recognize biospheres that might be quite different from the Earth's one. It embraces the search for potentially inhabited

56. Panspermia Descriptive entry in The Encyclopedia of astrobiology, Astronomy, and Spaceflight. http://www.daviddarling.info/encyclopedia/P/panspermia.html

ALTERNATIVE FORMS OF LIFE ASTROBIOLOGY A B ... CONTACT entire Web this site panspermia An idea, with ancient roots, according to which life arrives, ready-made, on the surface of planets from space. Anaxagoras is said to have spoken of the "seeds of life" from which all organisms derive. Panspermia began to assume a more scientific form through the proposals of Berzelius Richter Thomson (Lord Kelvin) (1871), and Helmholtz (1871), finally reaching the level of a detailed, widely-discussed hypothesis through the efforts of the Swedish chemist Svante Arrhenius . Originally in 1903, but then to a wider audience through a popular book in 1908, Arrhenius urged that life in the form of spores could survive in space and be spread from one planetary system to another by means of radiation pressure . He generally avoided the problem of how life came about in the first place by suggesting that it might be eternal, though he did not exclude the possibility of living things generating from simpler substances somewhere in the universe. In Arrhenius's view, spores escape by random movement from the atmosphere of a planet that has already been colonized and are then launched into interstellar space by the pressure of starlight ("radiopanspermia"). Eventually, some of the spores fall upon another planet, such as the Earth, where they inoculate the virgin world with new life or, perhaps, compete with any life-forms that are already present.

Examples of such sites are an active or extinct hydrothermal deposit, a dry lake or a specific polar site. Had it been funded, the rover was to be built by NASA's Jet Propulsion Laboratory , based upon the Mars Science Laboratory rover design, it would have carried astrobiology -oriented instruments, and ideally, a core drill . The original plans called for a launch as early as 2016, however, budgetary constraints caused funding cuts.

Chemical evidence buried in rocks that formed during this major extinction indicates a devatated landscape with huge 'dead zones' in the oceans and runaway greenhouse gases in the atmosphere. Trapped Rover Finds Evidence of Water on Mars Topic: Mars Summary: Although NASA's Mars Exploration Rover Spirit is stuck in the soil of Mars, the rover is still gathering important data. The ground around Spirit holds evidence that water trickled into the subsurface fairly recently. The findings could have implications in the search for past or present life on Mars.
