| Re: Ancient impact on Mars Have you read my prediction regarding a Martian impact? How long have they been discussing a major impact, anyway? http://hypography.com/forums/earth-s...tml#post198641 |

PSR Discoveries:Hot Idea: Asteroids' low densities The basin in my view, however, would have been caused by melted water ice from the asteroid and not by the heat of impact alone. | |

Even a cursory understanding of materials science and bolide characteristics would demonstrate the impossibility of an impacting asteroid retaining even some of its coherence. Let's keep discussion of such unfounded ideas on the Urantia Book thread where they belong and leave this thread for realisitic discussion of this interesting major hypothetical impact. | |

Toward the topic, I was only addressing the main question which is simply, "Why the dual characteristic of Mars' surface?" In my previous posts, I simply wanted to point out that the prediction I made describes a low density asteroid spiraling inward slowly, almost like a moon, so that the angle of impact is extreme enough to carve the Valles Marineris while bouncing gently in the middle, then breaking up. The second bounce would have to be where Olympus Mons, which is not a verified volcano, and its three fragmented siblings currently reside. Note that asteroids are made of ice and dust/pepples and would not create an impact such as that which you and they conceive. PSR Discoveries:Hot Idea: Asteroids' low densities The two hypotheses are completely unrelated of course, except that in the OP, the "bolide" basin is created by a violent impact that melts/erradicates a lot of material while in my interpretation, the basin was created by melted water ice flowing and settling into the area. The reason there's no observable ice in the basin these days is that daylight melted and evaporated it little by little, forming Mars' pipsqueak atmosphere, oxidizing its red surface, and eventually forming the polar ice caps. The ice in the poles should be stratified with dust from storms. The basin should contain a different kind of dust as well as earth-like mineral and biological deposits. It's a legitimate and testable hypothesis. | |
