Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.

Here is one set of the sol417 stereo pairs, from the left in crosseye/anaglyph/parallel renderings:
"the alien instrument descended as dusts of ages fell away revealing a sort of portal, as if a long buried Cenote emerging from the deep to accept the sacrifice" |

Here is one set of the parallel renderings: Oh WOW. That is a HUGE amount of missing volume! Can that ALL be from compaction? I'm starting to think there is a void UNDER the duricrust, and the mole punched a small hole through which is allowing the soil to drop down into a void? |

Can that ALL be from compaction? It was partly wondering about this that prompted me to ask the question about densities a few posts back. Apart from the visible void there is the volume now occupied by the probe itself. If the regolith here is indeed very porous and lightly packed that would initially have helped the mole to sink. Maybe the hammering causes the stuff to collapse and there is now a much denser sand 'puddle' at the bottom of the hole. |

The presence of duricrust implies the previous presence of saline water from which the water departed. To some extent, this compaction must be showing us how much water there once was.
