    NASA seems to be asserting that because they are spheres they must have formed in water. Any geologist know why they could not be volcanic and still be spherical?

      Start here if you'd like. Short and sweet, and comes with a nice pretty picture. Dig for more if you'd like, it's out there and it's not even hiding. Them little boogers isn't volcanic. And oh yeah, NASA is NOT "asserting that because they are spheres they must have formed in water." Not at all. Not sure where you got that from, but you might as well go ahead and put it back, 'cause it's wrong.

      I'm not a geologist, but I've read the press release that explained this.

      The spheres appear uniformly through the strata laid down. Volcanic or meteor sources would be more likely to appear in layers of spheres -- one layer of spheres per erruption or meteor impact.

      Secondly, in this picture here, you can see that some of the spheres have merged as they met. If it was volcanic, they would have melted together (and flowed together) rather than merely intersecting. To a geologist, the shape of the merged spheres has "molecular compound formed on-site" written all over it.

  6. Really amazing stuff by Pottsynz · · Score: 3, Insightful

    I'd like to give major kudos to the people behind the rovers, it really is amazing we have a couple of robots buzzing around another planet actively doing science. We're unlocking the mysteries of a world thats not our own, thats pretty damn cool.

    "Now all we have to do is figure out what made the rocks in the first place and how long the water may have been involved in the 'soakings.' What a fun time!"

    Kudos to the rover guys, NASA has failed to produse Martian news like this since before I was born.
