Starting a new thread as we leave the landing site and start the drive around Seitah. It will probably be quite fast unless something interesting turns up in the ejecta of the craters along the path.
Here is a circular panorama for sol 379, already north of the landing site. Maybe there will be some drive-by shots of the landing site itself. Phil -------------------- ... because the Solar System ain't gonna map itself.

QUOTE (tau) A piece of hardware lost or dropped during descent and landing? Nope. Too big.QUOTE (tau) A meteorite? Nope. Shape and how it seems to 'fit' against a back rock suggests in situ.QUOTE (tau) A piece of Martian rock that was hurled here from elsewhere by a meteorite impact? Eh, perhaps, but as above, based on what appears to be a 'fit' to the rock behind, it would have to be hurled, buried, then excavated.QUOTE (tau) What could that bright thing on La Orotava crater wall be? My initial guess would be a pegmatite pipe.When molten rock cools, the result is much like leaving a soda or beer in the freezer too long, aka "apple jack" (early distillers let hard cider freeze out the water, then poured out the concentrated liquor)* When molten rock chambers cool, they 'freeze out' minerals which snow down, until you're left with a magma enriched in the material with the lowest freezing point- which is usually enriched in metals, often white, and called "pegmatite". *disclaimer- don't try at home. Freeze distillation doesn't separate methanol (bad-go blind) from ethanol (good, you've made apple brandy/schnapps). To separate methanol from ethanol, you need heat distillation and condensation (e.g. a moonshine still) |
