There are so many of these things; the soil all around the crater rim and bedrock is covered with them. They might be concretions all right, but why so many of them, as compared to most earthly examples? The vast number of them may itself indicate biological involvement, a fascinating idea. Could so many have just eroded out of bedrock in the normal sense? Squyres himself has said in earlier JPL briefings that some spherules come from the bedrock (we can see that) but that many probably do not. If the rover goes out onto the flat plain and the plain itself is covered with them, then what? Some of the pancam images I've looked at so far seem to hint at that, but they may be clustered just around the crater(s), we don't know yet. But soon now we will see. They could still be just "normal" concretions, with no biological involvement, but I think this hypothesis is an interesting possibility at this point, that should not be dismissed too quickly. There are also similar ideas now regarding zinc spherules on earth that can be created by colonies of microbes: http://www.sciencenews.org/20031115/bob9.asp Also, in this new Astrobiology Magazine article, they mention how even the sulfate-eating bacteria can produce round spores when they go dormant, with a photo of one, although those are probably a lot smaller, not sure (no size indication given). It includes quotes from Benton C. Clark who was in the NASA press conference panel and seems rather open-minded to the possibility of Martian life, at least in this form (see below): http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid=858&mode=thread&order=0&thold=0 or http://tinyurl.com/ytjvz As for there being no biologists in the press conference panel, as I've seen mentioned in various places - not quite accurate. I found this reference in another forum for Dr. Benton C. Clark (who presented the spectrometer results). His background is biophysics and he chairs the External Advisory Committee for the NASA Center for Research and Training in Exobiology at the University of California San Diego and Salk Institute: http://nai.arc.nasa.gov/video_archive/clark.cfm http://stardust.jpl.nasa.gov/news/bio_bclark.html There's a lot more to his bio than just Lockheed-Martin which was mentioned in the official press release (and so the reporters there probably didn't know this either).
