  • We all came from Mars, don't you know it? There was a series of "extreme weather events" and we had to escape. Now there is some guy dreaming to get back home. /s

  • It is quite remarkable that the question of life on mars (or not) hasn't been answered conclusively despite a lot of human effort to get an answer.

  • What I like about Mars stories like this is that they are a good antidote to both extremes: "we found life!" and "there is nothing interesting here"

  • Tangential, but really looking forward to what Europa Clipper[0] finds in its flybys.

    The delay in communication makes ambitious manoeuvres challenging - perhaps advances in AI (and by extension robotics) helps build much more autonomous space rovers. This could enable us, for example, to evaluate the samples by sending wet microscopes with the rover itself.

  • It would not be surprising if ancient life did exist on Mars, since impacts would likely have sent life back and forth between Earth and Mars (and possibly Venus).

    For the same reason, the existence of ancient life on Mars would not show that life is likely to arise on Earth-like worlds, since one could not conclude it was an independent event.

  • The article is good but the title is a bit too slippery a statement in my opinion. The article is saying more evidence is consistent with possible ancient life on Mars. In astrobiology the massive problem is that geology can imitate biology. The presences of minerals formed by microbes on Earth does not prove microbes are involved in their production on Mars, it is a big jump to make.

    I don't think I have heard the word benevolent used in that context before.
