Phoenix Mars lander 'tastes' first sample of water ice.
Updated 19:43 01 August 2008 NewScientist.com news service Devin Powell "After weeks of struggling to scrape icy material from just below the surface of Mars, NASA's Phoenix lander has collected and analysed its first sample of water ice. "We've finally touched it and tasted it. It tastes very fine," said team member William Boynton of the University of Arizona in Tucson. "On Wednesday, Phoenix's robotic arm scooped out a sample of dirt from a 5-centimetre deep trench called "Snow White", which it began digging in June. The soil was transferred to one of the lander's eight TEGA (Thermal Evolved-Gas Analyzer) ovens and slowly warmed to 2 °Celsius (36 °Fahrenheit). "When the temperature reached 0 °C (32 °F), the instrument had to add extra heat to continue warming the sample – the signature of frozen ice melting. TEGA's mass spectrometer also directly detected minute traces of water." http://space.newscientist.com/articl...water-ice.html Interestingly, Boynton also said that salts in the soil may have allowed ice to melt that would have the stickiness seen in the Phoenix samples. From the article: "On 15 July, the team used a sort of drill called a rasp attached to the scoop to cut cores out of Snow White and collect the shavings in a compartment on the back side of the scoop. But when the scoop was turned upside down, the sample stuck to the walls inside. Martian salt may have melted the ice and made the soil sticky, says Boynton." Note that the ice just turning into a gas, sublimating, would not make the soil sticky. Keep in mind also that salts also depress the pressure requirements for liquid water as it does the temperature requirements. Bob Clark |

Phoenix then scratches its own butt with shovel until it freezes solid. 8) NASA declares mission "a rousing success." 9) Three remaining Martians attack Earth, retaliating for destruction of their only water reservoir. -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

You’d think by the way it’s getting mainstream touted, that it’s worth 1e8 ppb of nearly pure h2o, though I can’t but wonder what it really is. What's the big ass holdup this time? (too much water? mass spectrometer broken? no frozen bedrock to test? Ovens not getting hot enough? Ovens shorting out? Phoenix farting too many bricks?) Perhaps the “Compost heap of NASA crap” is finally perking, fermenting and flowing up hill like it should. Perhaps their next mission should be launched by Falcon 9 or F9 Heavy, thus once having fallen back into the ocean they’ll have discovered water (salty water none the less), and if their orbit destination manages to get submerged enough, they might even discover an entirely new species of complex life surviving where it’s entirely inhospitable to us mere humans. http://www.spacex.com/falcon9.php (fully submersible orbit capable) http://www.spacex.com/falcon9_heavy.php (bigger submersible payload capable) As per usual, powered by our hard earned public loot and NASA’s perpetual spew of flatulence. To think, all we willage idiots have to do is keep forking out our hard earned loot, and suck it up. ~ Brad Guth Brad_Guth Brad.Guth BradGuth |

As the mothership larger than the planet Earth silently glides through the night sky.... NASA and the owned media are celebrating the so-called discovery of "water" on mars. Nerdy NASA employees are seen cheering and raising their scrawny arms in dorky salutes of their so-called "victory" which means that the possible discovery of LIFE on other planets might even be thinkable now! Maybe some day soon a bacterium or some fossilized Johnson off of a single celled organism will forge the science of mankind's "civilization" forward to new heights! Meanwhile the giantic mothership opens a huge hatch and lands the hundreds of thousands of scout ships that were surveying the primitive planet that night.... NASA! Feh. |

Bob Clark By far the least costly mission of sending humans to Mars, there are any number of robust men and I'd bet a few hot chicks on death row, or of those unfortunate souls in some kind of irreversible terminal illness situation, that would likely pay top dollar (including the ultimate price) for a one-way ticket to Mars. This alone would cut the budget by as much as 75%. So, I would agree and otherwise argue that such willing folks should not be denied their chance at being of the first to step, pee and poop on Mars. I'd bet we'd sell 100 of those one-way tickets to ride within the first year, and over a thousand tickets sold if we allowed all nationalities and devout religious types to apply. We might even raise an extra ten billion dollars this way, especially from those of us willing to pay extra for getting rid of GW Bush, Dick Cheney and Henry Kissinger. Supposedly Mars is still holding onto its water, and thereby we most likely have other than terrestrial life to behold. And yet there’s still not so much as one reported part per billion worth of any objective mass spectrometer accounting for all of that supposed water. You’d think by the way it’s getting mainstream touted that it’s worth 1e8 ppb of nearly pure h2o, though I can’t but wonder what it really is. Is the systematic excluding of evidence their one and only option at their disposal? What's the big ass need-to-know holdup this time? (zero/zilch water? too much water? mass spectrometer broken? no frozen bedrock to test because there’s too much dry-ice in the way? Ovens not getting hot enough? Ovens shorting out? Phoenix farting too many bricks?) Perhaps the forever growing “compost heap of NASA crap” is finally perking, fermenting and flowing up hill like it should. Perhaps their next Mars mission should be launched by Falcon 9 or F9 Heavy, thus once having fallen back into the ocean they’ll have discovered water (salty water none the less), and if their orbit destination manages to get submerged deep enough, they might even discover an entirely new species of complex life surviving where it’s entirely inhospitable to us mere humans that supposedly came from the ocean to begin with. http://www.spacex.com/falcon9.php (fully submersible orbit capable) http://www.spacex.com/falcon9_heavy.php (bigger submersible payload capable) As per usual, rocket powered by our hard earned public loot and NASA’s perpetual spew of infomercial hype and flatulence. To think, all we village idiots have to do is keep forking out our hard earned loot, and then suck it up each time a spendy mission goes for the deep blue kind of station-keeping orbit. ~ Brad Guth Brad_Guth Brad.Guth BradGuth |

Muttering Martians make another trip to Earth to collect the liquid to refill their fountain. /BAH |
