Well .. ya go away for a week … and it all seems to revert back to those boring old conformist mainstream ideas … so here we go … yet another scientist seeing Mars for what it is … and what it may have always been … dry !
Martian water vs. the volcanoes
Quote:
For decades NASA has been "following the water" on Mars with hopes of finding signs of alien life there; or at least signs that future colonists won't die of thirst. Now a Texas geologist has dared to revive an old, almost heretical idea -- backed up with all the latest data -- that the Red Planet has been bone dry for billions of years.
…
Mars' spectacular grand canyons were not carved by catastrophic floods, says Texas Tech's David Leverington, but by slippery, low-viscosity lavas. This lava hypothesis fits happily within a wider geological framework of Mars and compares well with similar channel-like features on the moon and Venus, he said.
If Leverington is right, the odds of life on Mars plummet to near zero.

Yep … well whilst some of the flows we see on Mars may have originated from lava, some may have been carved by ablating CO2 also .. but the noteworthy item here is the realisation that the past "big" water on Mars, is now being referred to as a hypothesis:

Just because there are some problems with the water hypothesis is no reason to throw it out entirely

… Ok .. so finally we see some truth coming out in the media … all this business about the overwhelming geological evidence for big water flows in Mars' past is now devolving into mere hypothesis ! And the follow-on impact of this is that there may have
never been any major planetary-wide environmental catastrophe resulting in the disappearance of any major water (it may never have been there to start with !) … like what we've all been led to believe for yonks !
Cute ..
