As I noted in another group, I did read your article and I'm sorry for delaying my contribution (which was interupted by my recent trip abroad). In fairness, though, since you attended GeoMars 2001 and I did not, perhaps your article should stand alone as is. I'll probably put something more generic together regarding H2O on Mars and send to your for comments before submitting to SpaceDaily. To be sure, there is a great deal of work being published or in the works, and I haven't had time to wade through everything as thoroughly as I normally would like. Currently, I have about 75 papers (including pre-prints from JGR-Planets and Nature) on my "to read" list, with more on the way ;-) In any event, I'll let you (and Simon) know real soon when I have something coherent finished.
