If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck.

    The duck test.

    Currently there are several countries focussing on Mars. There is a lot of excitement because what returning images are suggesting is that Mars is just a more mature version of Earth, that it once had running water and geological processes just like Earth. And that rock formations that we can see through the lens are very similar to ones to be found on Earth. But should we believe what we see? Are we seeing what we think we see? I don’t trust my wing mirrors on my car too readily and prefer to check over my shoulder if changing lane on a motorway. And similarly much prefer to be on location rather than look through the lens of a camera. Maybe this time around, some of the images we get back will be a bit more convincing but many so far leave me wondering that we aren’t necessarily seeing what we think we see.

    Landing site for Mars 2020 Rover. It looks like someone has been driving a four by four down there already?

    I haven't followed this mission and I've not looked up the landing site, but isn't that a mud slide through that breach?

    edit:

    This is from the Nasa site, it's a bit clearer

    I don't see anything that looks artificial. Looks natural, dead and barren to me?

    For scale the entire crater is 30 miles wide.

    I agree it is natural but I am sure John knows that :)

    This is Jezero crater, very old I expect, you can see the landing site to the left, you can explore all this in Google Earth Pro by switching to Mars :)

    I gather Jezero is Czech for the word lake. I wonder why they chose that site.
    Actually aerial photos can be very revealing such as ones NASA produce for Earth. So hopefully they can come up with some really good shots of Mars.

    I get it :lol:

    Yeah I wonder if they will find an abandoned Land Rover Discovery somewhere :D

    This is a more extreme example of what I was referring to... if we go by a photo of the moon we might say that it is a man’s face peering down.

    That's a very pushed photo :D (the one on the right)

    This is one of mine :)

    I find it very hard to see the man in the moon unless there is a lot of atmosphere blurring it a bit and it is low in the sky, like harvest moon time.

    The shot was taken a very long time ago in Scotland with this rig

    Yeah humans are driven to find pattern, we find pattern everywhere.

    At various times we actually get to see a little further round the back of the moon at both sides, due to angle of view, although the moon is tidally locked its distance varies by a lot over time and this affects our view, the illusion is more prominent I think when some of these features are more central to our view.

    I thought it was because my eyesight is not as good as it once was and I wasn't wearing specs ;)

    This explains the reason behind the site selection. Jezero Crater



    It looks like they are sending up a miniature helicopter type drone called “Ingenuity” as a step forward in surveillance of the planet. And they aim to cut some geological cores that they aim to store until they can be retrieved at a later date.

    Yes. According to NASA they believe it is a river canyon slicing through the the crater rim and depositing material in the crater lake when it was a lake. They mention clay. So they think there might be an abundance of evidence of life. So I can see what they are getting at. It looks plausible.

    As a for instance, features like the one they hope to look at are commonplace in the Gulf of Mexico where huge oil deposits exist and are being produced from. Deepwater Horizon was drilling in such deposits.

    So it will be interesting to see what they find. Maybe even some Unobtainium.
