NASA has called a 2 p.m. news conference for Thursday "to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life." The group includes Pamela Conrad, author of a paper on geology and life on Mars; and James Elser, an Arizona State University professor involved in a NASA-funded program that emphasizes looking at the chemistry of environments where life evolves (and not just looking at water or carbon or oxygen); Felisa Wolfe-Simon (an oceanographer) has written extensively on photosynthesis using arsenic recently (she worked on the team mentioned in this article); Steven Benner (a biologist) is on the "Titan Team" at the Jet Propulsion Laboratory; they're looking at Titan (Saturn's largest moon) as an early-Earth-like chemical environment. This is likely related to the Cassini mission.
The space agency did not release more details, but the list of news conference participants is telling, according to blogger Jason Kottke.
"So, if I had to guess at what NASA is going to reveal on Thursday, I'd say that they've discovered arsenic on Titan and maybe even detected chemical evidence of bacteria utilizing it for photosynthesis (by following the elements)," Kottke wrote.
We'll find out in short order...
