It isn't. You can access most content older than 12 months (including Malin & Edgetts paper) for free, but you have to register as a user first. Details at: Thanks. I forgot to check that out. There were several papers being discussed, and I didn't make it clear which one I was talking about. I was trying to get the latest paper titled "Present-Day Impact Cratering Rate and Contemporary Gully Activity on Mars." Thanks to a philanthropic donor, I now have that. http://www.sciencemag.org/about/access.dtl tty The search for life on Mars is a tricky problem. We are only very recently learning what Mars is really like. It seems quite possible that any microbes launched onto the surface environment might be toasted, but life is a resilient and robust thing. Life has managed to evolve quite a number of mechanisms to deal with challenging environments on Earth. Who yet knows what it is capable of elsewhere. Assuming it can not survive on the surface of Mars, we might need to capture it as it is expelled from a more benign, subsurface environment. Drilling down to a wet reservoir seems to be a hit-or-miss proposition unless we can accurately identify and rove to the correct locations. Yes, there are more frigid places near the outer planets where liquid water may exist, but Mars is where we need to do more exploration. -------------------- ...Tom
