Rover images confirm Jezero crater is an ancient Martian lake: The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.:

The first scientific analysis of images taken by NASA's Perseverance rover has now confirmed that Mars' Jezero crater -- which today is a dry, wind-eroded depression -- was once a quiet lake, fed steadily by a small river some 3.7 billion years ago.

The images also reveal evidence that the crater endured flash floods. This flooding was energetic enough to sweep up large boulders from tens of miles upstream and deposit them into the lakebed, where the massive rocks lie today.

[...] "We now have the opportunity to look for fossils," says team member Tanja Bosak, associate professor of geobiology at MIT. "It will take some time to get to the rocks that we really hope to sample for signs of life. So, it's a marathon, with a lot of potential."

    It doesn't even need to be superconductor. A power line this big would cost few billion dollars on Earth.

    True, but you'd need an ongoing source of power. Be a toss up whether that was cheaper than an ongoing source of cooling for 12,000 km of cable. Either way, it would be a small cost relative to re-gassing the planet.
