Mars was Wet, but was it Warm?
Mars is frozen today, but when it was young there may have been liquid water on its surface. What does the latest evidence indicate about the ancient martian climate? At the recent Astrobiology Science Conference (AbSciCon) 2010, Jim Kasting of Penn State and Brian Toon of the University of Colorado discussed the possibility of a warm and wet Mars. A primary point of debate was whether or not physical features on the surface of Mars required extended warm, wet periods to form, or if short-term warming generated by impacts was enough.Source: [astrobio.net]

Houston, We’ve Had a Conference…
Banner for the 2010 Astrobiology Science Conference.
The 2010 Astrobiology Science Conference was a wild rodeo of ideas, debates, and scientific discovery. Although there was far too much science presented over four days to cover in full, this round-up provides a few highlights.
This years AbSciCon was held in League City, Texas, from April 26 to April 29.Source: [astrobio.net]

AbSciCon 2010 a Success
Researchers debate the astrobiological merits for exploring Jupiter's moon, Europa, and Saturn's moon, Titan, in the dialog session "Titan Versus Europa - Potential for Astrobiology." Left to right, Robert Shapiro, Kevin Hand, Olga Ballesteros and Dirk Shulze-Makuch.
Astrobiologists from around at the world gathered last week near the Johnson Space Center in League City, Texas, to participate in the Astrobiology Science Conference 2010: Evolution and Life: Surviving Catastrophes and Extremes on Earth and Beyond. The official program of AbSciCon took place over four days from April 26-19. Early arrivals on the 25th of April were also treated to primer lectures on some of the scientific disciplines that would feature during the conference, as well as a panel discussion relevant to this years conference focus – ‘Top Ten Catastrophes’.

AbSciCon '08: Second Meeting of the Origins of Life Focus Group
The meeting took place on April 17, 2008 during the AbSciCon 2008 in Santa Clara, California. 38 scientists participated in this meeting. As previously, this report summarizes main conclusions not only from the meeting, but also from a number of conversations that I had with members of the Group during the conference.
The agenda consisted of four items:
- A brief report on the upcoming ISSOL meeting in Florence.
- Report from my presentation on our focus group to the NAI Executive Council on 4/14/2008.
- Presentation of our new website.
- General discussion.
ISSOL. We expected that the ISSOL presentation would be done by...

NAI Student Poster Competition at AbSciCon 2008
The competition was fierce! Of 37 posters representing the full gamut of astrobiology research areas, six finalists moved into second round judging, and four awards were made. Please join NAI in thanking our judges and congratulating this year’s winners:
First place, $2,000, and the Frank Drake Award goes to Tsubasa Otake of Pennsylvania State University for his poster “Theoretical investigations of equilibrium and surface adsorption effects on mass-dependent fractionation in multiple sulfur isotope systems.”
Second place, and $1,250 goes to Pamela Hill of the University of California, Los Angeles for her poster “Non-redox Iron Isotope Signatures.”
Third place, and $750 goes to...

AbSciCon '08: The Astrobiology Universe
The opening speaker at the 2008 Astrobiology Science Conference (AbSciCon), Lord Martin Rees of the University of Cambridge, said that our universe may just be one of many. Multiple universes could be stacked sideways like sheets of paper, separated by only a thin margin of space. We would never know they were there unless we could be awakened to the existence of that other dimension.This could have been the theme of the conference. Every morning and afternoon, nine separate talks were given simultaneously, often just separated by thin walls through...
