Scientists have concluded that mineral veins seen by Curiosity in Gale Crater were created when a lake existed there.

The study suggests that the veins formed as the sediments from the ancient lake were buried, heated to about 50 degrees Celsius and corroded. Professor John Bridges from the University of Leicester Department of Physics and Astronomy said: “The taste of this Martian groundwater would be rather unpleasant, with about 20 times the content of sulphate and sodium than bottled mineral water for instance!”

    Mars stinks like rotten eggs. I don’t think bottled Martian water will become a big seller on Earth (but who knows, people are crazy). It might however become a successful consumer product on the local Martian market, since it doesn’t have any competitors. You’ll get used to the stench and stop thinking about it, I understand this is how we react to sulfates, it numbs our nose. Just very surprising for your guests.

    Bob, I have sent the following email to the lead scientists who wrote this paper – – –

    Any bets on reply(s)?
    Susanne and John,

    My name is Phillip Veerkamp.  I am a 72-year-old retired un-credentialed “astrobiology hobbyist”.  I have zero scientific reputation at stake.  I am absolutely free to jump to wild conclusions.

    In the past few days Curiosity has returned  pictures from at least two “brushed” rocks from the Mars Hand Lens Imager (MAHLI) images for Sol 1416 –


    Mars Hand Lens Imager (MAHLI) images for Sol 1418 –

    My meager geology training says that there is one and ONLY one explanation for naturally occurring fibers in mudstone – BIOLOGICAL.

    I say we are looking at an ancient Martian “peat bog” [rough analogue].

    What say you?  J

    I do not expect you guys to risk your reputations through casual speculation, but can you comment? . . . safely?

    Kindest regards,

    Phil Veerkamp

  • You might get a reply, but it will be something likely along the lines that we doubt that is the case, but we are looking at these features very closely. And I would not expect them to say much more than that, at this point, if that.
