Finds Along the Frontier.


“In a teleconference, Kaltenegger said that the planet is at the warm edge of its star’s habitable zone, as if ‘standing next to a bonfire.’ That means the planet would require a lot of cloud cover — which reflects starlight — to keep the surface cool enough to prevent any water from boiling, she said.“

Gliese 581g, meet HD85512b. Among the 50 new planets astronomers announced on Monday is a “Super-Earth” that lies within the inhabitable zone and could hold water. “The new super-Earth is 3.5 times the mass of Earth.“

And, how are we going to get there, you ask? While DARPA works its mojo, NASA announces its most recent plans for a successor to the Shuttle: A new Space Launch System. “Administration officials said the new rocket system…would be the most formidable launch system deployed since the Saturn V…The new rocket coupled with a deep-space crew capsule already under development should enable an un-crewed test flight of the exploration system in 2017 and a crewed test flight by 2021, officials said.” If history is any guide, you’ll probably want to tack a few years on to those dates.

While we wait, here’s another interesting cosmic find to ponder: Astronomers have found an honest-to-goodness twin-sunned Tatooine in Kepler 16b, 200 light years away. “‘This is an example of another planetary system, a completely different type that no one’s ever seen before,’ Doyle said. ‘That’s why people are making a big deal out of this.’“

Strapped to the Rocket.


“There is no shortage of proposals for radically innovative space launch schemes that, if they worked, would get us across the valley to other hilltops considerably higher than the one we are standing on now–high enough to bring the cost and risk of space launch down to the point where fundamentally new things could begin happening in outer space. But we are not making any serious effort as a society to cross those valleys. It is not clear why.“

In Slate, sci-fi author and technophile Neal Stephenson discourses on what rockets tell us about innovation and the course of technology over time. “The phenomena of path dependence and lock-in can be illustrated with many examples, but one of the most vivid is the gear we use to launch things into space.“

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.

Express Shuttle.

A month into his new gig, new NASA administrator Michael Griffin argues for speeding up the shuttle replacement by four years, with a new proposed launch date of 2010. “To execute the new strategy, sources said, Griffin intends to assemble a small, Apollo-style team of NASA experts and scrap the current plan to have two civilian contractors compete for several years for the right to direct development of the exploration vehicle.”

Moon, Mars, and Beyond.

“I always knew that I would see the first man on the Moon,” once quipped Jerry Pournelle. “I never dreamed
that I would see the last.” Hopefully, we can now prove him wrong. Dubya officially announced his space plan in front of NASA’s DC headquarters today, and the upshot is this: More scientists, less entertainers, a Research Lab in every city, and he’s going to disband all the Spearmen and Pikemen still lying around so he can build the SS Planetary Party Lounge.

Ok, just joking…some of y’all out there might think that was funny. At any rate, the plan is the ISS by 2007, the CEV by 2014, the moon by 2015, and Mars thereafter. Say what you will about election year boondoggles, but I still think creating and funding long-term goals for NASA is a wise investment. (Besides, if you want to cry election-year boondoogle, you don’t need to go any farther than Dubya’s ridiculous $1.5 billion marriage-promotion plan.) NASA still has serious organizational and cultural flaws, sure, but I think it’ll be better able to address them if there’s at least some semblance of a “vision thing” to build on.
