Marshes of the Moon.

“‘It’s really wet,’ said Anthony Colaprete, co-author of one of the Science papers and a space scientist at NASA Ames Research Center at Moffett Field, Calif. He and his colleagues estimate that 5.6% of the total mass of the targeted lunar crater’s soil consists of water ice. In other words, 2,200 pounds of moon dirt would yield a dozen gallons of water.“

In keeping with recent studies, NASA is set to announce that there appears to be quite a lot of water on the moon, which would greatly facilitate setting up shop there. Alas, “the U.S. likely won’t be involved in manned voyages to the moon anytime soon…But other countries are gearing up. China has pledged to land astronauts on the moon by 2025, and India has plans to do the same by 2020. Japan wants to establish an unmanned moon base in a decade.” And, hey, why go to the moon when you can spend a decade in Afghanistan?

Earth Too.

“‘We’re pretty excited about it,’ admits Steve Vogt, of the University of California, Santa Cruz, a member of the team, in a masterpiece of understatement. ‘I think this is what everyone’s been after for the past 15 years.’” And then some! Apparently, astronomers have discovered the most Earth-like planet yet in Gliese 581g, a relatively short 20 light years away.

“[I]t probably has a solid surface just like Earth. Much more important, it sits smack in the middle of the so-called habitable zone, orbiting at just the right distance from the star to let water remain liquid rather than freezing solid or boiling away. As far as we know, that’s a minimum requirement for the presence of life.“

Some might remember that Gliese 581c was all the rage two years ago. Apparently, this one — in the same solar system but only just discovered — is even closer to the real deal. (Good thing the NASA authorization just passed…)

Titan A.E.?

“We suggested hydrogen consumption because it’s the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth. If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.“

In potentially very big doings, two astrobiology papers suggest that some form of life is currently consuming gas and fuel on Saturn’s moon of Titan (The gas being hydrogen and fuel being acetylane, which would make sense for a methane-based life form.) “We suggested hydrogen consumption because it’s the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth. If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.’” Yes, that would be exciting.

Update: NASA’s Chris McKay advises scientific caution. “This is a still a long way from ‘evidence of life’. However, it is extremely interesting.”

Farewell Atlantis.

“‘We’ve got a new antenna on the space station, a new six-pack of batteries, a new module docked to the station, and generally have defeated the forces of evil, so we’re very happy about how things have gone,’ said spaceman Garrett Reisman.’” Farewell, Atlantis, the first of the three remaining space shuttles to be decommissioned. “This was Atlantis’ 32nd journey; the shuttle logged its 120-millionth mile shortly after midnight.” Update: Amazing pic added via The Big Picture.

Twenty Years of Hubble.

“Nature and Nature’s laws lay hid in night: God said, Let Newton be! and all was light.” Let’s not forget Hubble too: As of today, Humankind’s first great orbital telescope turns 20. And to think we’re only at the beginning… [Greatest hits | A brief history of orbiting observatories | what’s next.]

The Moon Awash.

“Within 40 small craters, one to nine miles wide, they estimated 600 million metric tons of water. Perhaps most notably, ‘It has to be relatively pure,’ said Paul Spudis, the principal investigator for the instrument that made the discovery.“

By way of a friend, scientists find more evidence of lots of water on the moon. “That is significant, because the ice in these craters could be easily tapped by future lunar explorers — not just for drinking water, but also broken apart into oxygen for breathing and hydrogen for fuel.” Hmm. Maybe it’s time to start thinking of ways to get up there…

Partial Eclipse.

“The troubled and expensive Ares I rocket that was to replace the space shuttle to ferry humans to space will be gone, along with money for its bigger brother, the Ares V cargo rocket that was to launch the fuel and supplies needed to take humans back to the moon. There will be no lunar landers, no moon bases, no Constellation program at all.” As expected (and feared) earlier this year, the Obama administration’s proposed NASA budget for the next five years cancels any and all plans to go to the moon anytime soon. “‘We certainly don’t need to go back to the moon,’ said one administration official.“

Sigh.

Ok, first off, the administration official who uttered the last sentence should be filed away next to Mr. Left of the Left and Ms. Pajamas as people who should no longer speak for the White House in any capacity whatsoever. Full stop, end of story. Putting my speechwriter cap on for a second: In most any political situation, ridiculing the dreams of an entire generation does not make for particularly good messaging.

Anyway, anonymous WH official aside, NASA administrator Charles Bolden sounded a better note about all this: “We’re not abandoning anything. We’re probably on a new course but human space flight is in our DNA. We are not abandoning human space flight by any stretch of the imagination. We have companies telling us they’re excited to get humans off this planet and into orbit. I think we’re going to get there and perhaps quicker than we would have done before.“

And, to be clear, the administration’s NASA budget increases the agency’s funding by $6 billion over the next five years. The new budget ups research and development spending into cheaper heavy launch mechanisms, emphasizes more robotic exploration missions and observational experiments into climate change, extends the life of the ISS (although, with only five more shuttle missions remaining, other nations will have to help service it), and works to promote the various commercial space enterprises moving along right now.

All of this is well and good, but it would be nice to see some recognition of the civic importance of manned space flight by this administration. In their words, NASA is scrapping Constellation on account of it being “over budget, behind schedule, and lacking in innovation due to a failure to invest in critical new technologies.” And, given that we still had a lot of the expenditures before us, I suppose now was as good a time as any to kill the program if it’s not the right direction to go in.

That being said, how many more times are we going to do this? We keep stopping and starting and stopping and starting our post-Shuttle plans for space, so that now, after five final shuttle missions this coming year, we will longer have the capability anymore as a nation to send men and women into orbit. “If implemented, the NASA a few years from now would be fundamentally different from NASA today. The space agency would no longer operate its own spacecraft, but essentially buy tickets for its astronauts.” Forty-one years after we first reached the moon, that’s just plain sad.

Ultimately, the central finding of the Augustine commission’s final report, released this past October after extensive study of NASA’s current situation, is a sound one: “The U.S. human spaceflight program appears to be on an unsustainable trajectory. It is perpetuating the perilous practice of pursuing goals that do not match allocated resources.” In other words, we’ve been trying to talk the talk without walking the walk. If we’re going to get serious about manned space flight, we need to stop piecemealing NASA and start making manned exploration a funding priority.

In total, the agency is slated to get $100 billion over the next five years. To put that number in perspective, that’s less than a fifth of our defense budget for 2011 alone, and that’s going by the most conservative numbers around — NASA’s five-year budget could be closer to a tenth of next year’s defense spending. (For its part, the Augustine commission set a price tag of $3 billion a year to get serious about manned exploration.)

If we had put anywhere near that kind of money into exploration and R&D over the years, would we now be in this position, where we face the Hobson’s choice of replicating expensive 50-year-old launch tech or being completely grounded as a nation? The lack of thinking about our long-term priorities sometimes is staggering to me. I’ve said this before, but I still believe it holds true: Short of possibly genomic research and advances in AI, nothing we do right now will matter more centuries or millennia hence than establishing a presence off-world…if we even have that long. Not to get all Jor-El up in here, but we really have to start getting serious about this.

We Have Ignition.

“Although that panel suggested a $3 billion boost to NASA’s $18.7-billion-a-year budget in order to take a firm next step in human space flight, Obama’s support for a $1 billion bump next year represents a major coup for the agency given the ballooning deficit and the continuing recession. And NASA just won a $1 billion boost from Congress for 2010 in a bill signed by the president.” By way of another friend, President Obama backs increased funding for NASA’s new heavy launcher. “The president’s decision to go with the second option is a major departure from his 2010 budget plan, which called for a 5% increase in 2010–the boost just approved by Congress–but then remaining flat through 2014.“

Good, although I do wish he’d gone the full $3 billion. In the great scheme of things, not much we do is of larger importance than manned space flight. And 10,000 years from now, people aren’t going to remember or much care how many Joint Strike Fighters we built in the Twenty-Tens. But they will know whether or not we took significant steps to leave the cradle and move off-world.

A Hot Mess.

“‘There’s going to be all kinds of weird stuff out there,’ said Alan Boss of the Carnegie Institute of Washington, who wasn’t part of the research. ‘This is an unparalleled data set. The universe really is a weird place. It’s fantastic.’” In the midst of its current planet–hunting sweep, NASA’s Kepler telescope discovers two examples of a new type of heavenly body that are “too hot to be planets and too small to be stars.” (Although some think they’re recently-born planets; others dying “white-dwarf” stars.) “‘The universe keeps making strange things stranger than we can think of in our imagination,’ said Jon Morse, head of astrophysics for NASA.”

Waterworld.

“Charbonneau said it’s unlikely that any life on the newly discovered planet would be similar to life on Earth, but he didn’t discount the idea entirely. ‘This planet probably does have liquid water,’ he said.” Don’t mean to turn GitM into the We Found a Planet Weekly, but this also seems like big doings: Astronomers discover a watery, Earth-like planet relatively nearby. (As in 40 light years away, orbiting GJ 1214b.) “While the planet probably has too thick of an atmosphere and is too hot to support life similar to that found on Earth, the discovery is being heralded as a major breakthrough in humanity’s search for life on other planets.” I’ll say.

Update: “‘I was instantly excited because the glint reminded me of an image of our own planet taken from orbit around Earth, showing a reflection of sunlight on an ocean,’ Stephan said. ‘But we also had to do more work to make sure the glint we were seeing wasn’t lightning or an erupting volcano.’” Might be some more water closer to home too: NASA confirms liquid on Saturn’s moon of Titan.
