"The last Twitter post said it all: "01010100 01110010 01101001 01110101 01101101 01110000 01101000."" Or, in other words, Ground Control to Phoenix Lander: You've really made the grade. Having seemingly succumbed to the Martian winter at last, the Mars Phoenix Lander is pronounced deceased by NASA. "NASA official Doug McCuistion counseled people to view Phoenix’s end as 'an Irish wake rather than a funeral. It’s certainly been a grand adventure.'...While some followers said farewell to Phoenix in computer language today, others kept it simple. 'Good bye Phoenix, I love you :(,' said user patach."
ESA's Mars Express sends back some impressive postcards from Mars. "Over the last five years its stereo, high resolution camera has taken thousands of images of the surface, revealing the planet's awe inspiring beauty in unprecedented detail."
"'There's nothing about it that would preclude life. In fact, it seems very friendly,' said mission scientist Samuel P. Kounaves of Tufts University. 'We were flabbergasted.'" Hope y'all like asparagus: Early tests by the Mars Phoenix seem to indicate that the Martian soil is more nutrient-rich than anyone expected. "Carbon-based organic material, however, has not been found and may be impossible to detect with the equipment now on Mars."
"It's with great pride and a lot of joy I announce today we have found proof that this hard material really is water ice and not some other substance." Signs have pointed in that direction for awhile now, and particularly since the Phoenix landed. But now, it seems we have really, truly, definitively found ice on Mars. "The next questions to answer are what chemicals, minerals and organic compounds might be mixed in with the water. 'Just the fact that there's ice there doesn't tell you if it's habitable,' Smith said. 'With ice and no food it's not a habitable zone. We don't eat rocks — we have to have carbon chain materials that we ingest into our bodies to create new cells and give us energy. That's what we eat and that's what has to be there if you're going to have a habitable zone on Mars.'"
"'We were expecting to find ice within two to six inches of the surface,' said Phoenix principal investigator Peter Smith of the University of Arizona in a statement. 'The thrusters have excavated two to six inches and, sure enough, we see something that looks like ice. It's not impossible that it's something else, but our leading interpretation is ice.'" Well, it sure looks like ice. The Phoenix Mars Lander seems to have found its quarry almost immediately after landing. And where there's water...
"In my dreams it couldn't go as perfectly as it went tonight, we went right down the middle." Touchdown: NASA's Phoenix Mars Lander, soon to look for water in the Martian Arctic, lands without incident in the Vastitas Borealis plains. Congrats!
"Fact:...The density of Saturn is so low that if you were to put it in a giant glass of water it would float." And another pilfered link, which I meant to post last week: Megg of Quiddity points the way to 10 Cool Facts about Space (although, to paraphrase The Smiths, some facts are cooler than others.)
"If the current proposals to restart human exploration fail politically, indeed, the human space flight endeavor conducted under government auspices might well lose its momentum. I obviously hope that doesn’t happen. But it’s far from a slam dunk that we’re going back to the Moon and on to Mars." Two companion pieces to today's reflection on 50 years of Sputnik which I missed earlier: The Grey Lady hypothesizes about the next fifty years of space travel (suggesting its future as a public enterprise might be dubious) and takes a moment to consider the pop culture ramifications of the space age. "'At the level of government, I think we’re still struggling as to why we’re sending people to space,' Dr. Logsdon said. 'It’s a decent question, and I think it’s an unanswered question.'" (My answer to this question, for what it's worth, is here.)
NASA prepares a probe, named Phoenix, to dig for water on Mars. "Upon reaching Mars in May 2008, the spacecraft is to land just as the winter ice begins to recede around the polar cap."
New photos released by NASA from the Mars Global Surveyor seem to suggest the possibility of surface water on Mars, which would make any attempt to visit -- or colonize -- the red planet considerably easier (although, obviously, it's still no walk in the park.)
"'We certainly have not convinced the community, and that's been a little bit disappointing,' said David McKay, a NASA biochemist and leader of the team that started the scientific episode." Ten years later, CNN summarizes the simmering scientific dispute over a Martian meteorite, and the possible (albeit now seemingly quite unlikely) signs of life within.
"'The idea is to look at Mars and not think of it as a mysterious alien place,' Christensen said." Along the lines of Google Moon, one can now journey to Google Mars.
"I think that this mission will re-write the science books on Mars." More happy space news following the discovery of water on Enceladus: NASA successfully pilots the Mars Reconnaissance Orbiter into Martian orbit. "It was picture perfect. We could not have planned it any better." (Phew...looks like everyone successfully converted to metric this time.)
More James Cameron news: Harry of AICN has a wide-ranging conversation with the director which, if you can get past the usual Knowlesisms, reveals that Project 880 is in fact Avatar, and that Cameron has been working with NASA on a "Live Video Stereo Motion Image" (3-D) camera for the next Mars Rover.
