Newt, NASA, & the Moon (Updated January 30, 2012)

On Newt Gingrich on the Moon | Vintage Space:

Last week, Republican presidential hopeful Newt Gingrich made a bold claim: “By the end of my second term [2020], we will have the first permanent base on the Moon and it will be American.” On the surface, it’s an intriguing and even exciting prospect to space enthusiasts. A base on the Moon would extend human presence in the Solar System and act as a stepping stone on the way to Mars. Or, it could bankrupt NASA and prove to be little more than an ill-thought out, dead-end program. (Gingrich proposed a lunar base by 2020 in Florida on January 25, 2012.)

Gingrich promises moon base that could become 51st state | The Raw Story:

“By the end of my second term, we will have the first permanent base on the moon and it will be American,” the candidate insisted. “We will have commercial near-Earth activities that included science, tourism and manufacturing.”

“I accept the charge that I am an American and Americans are instinctively grandiose because we believe in a bigger future!” he exclaimed. “I want you to help me both in Florida and across the country so that you can someday say you were here the day it was announce that of course we’d have commercial space and near space. Of course we’d have a man colony on the moon that flew an American flag.”

Do we need a manned space program?  Yes we do. 

Does NASA need to get out of low Earth orbit?  Yes.

Will the private sector get us there?  Probably not.

Is Newt the leader we’ve been waiting for to get us re-focused on space?  Highly unlikely.

Is Newt the second coming of JFK?  Only in his own mind.

UPDATE: January 30, 2012

Phil Plait always has some good thoughts on these subjects.

The Newt-onian Mechanics of Building a Permanent Moon Base | The Crux | Discover Magazine:

I’m also not comfortable with raising the specter of another space race. Any attempts to get political motivation for exploring or exploiting space will inevitably bring to mind the idea of the Chinese. Have no doubts: the Chinese space program efforts are solid, and accelerating. When they say they want to have a moonbase by the 2020s, this is not bluster. They may very well be able to do it. But getting into a second space race with China would be suicide for our space program. Obviously, they have far more money than we do for such an endeavor. But more than that; what is the goal of a race?

Answer: to win. And what happens after you win? Look to Apollo for that. The goal of the first space race in the 1950s and 60s was to beat the Soviets. We did: America got to the Moon first. But after that, enthusiasm for Apollo died rapidly, and Apollos 18–20 were canceled about a year after Armstrong first stepped foot on the Moon. After all, once you’ve won, why keep running?

The point is, if we want to have a sustainable, permanent base on the Moon, then it has to live or die on its merits. As soon as we make it an “us versus them” scenario, the chances of long-term thinking drop precipitously.

Now, don’t get me wrong. When it comes to space exploration, in many ways I’m a starry-eyed optimist, but I’ve learned to temper that optimism with cold, hard, reality. And history shows that building a moonbase by 2020 according to Gingrich’s ideas not only won’t work, but would be a disaster for NASA.

NASA simply can’t do it in that timeframe; there’s no place in the budget for that sort of mission, and it’s unlikely in the extreme they’ll get extra funding for this. Perhaps because of that, Gingrich proposed taking 10% of NASA’s budget—some 1-2 billion dollars—and creating a new X Prize to motivate private industry to be involved. This has worked in the past as a catalyst for companies to work on difficult goals, like launching a piloted vehicle into space. However, going to the Moon and building a base would cost more than 1000 times as much as launching that sub-orbital rocket did, so it’s not at all clear an X Prize like this would work.

Add to that the money needed to keep the base running—an estimated $7.4 billion per year. That’s a lot of cash for a fledgling corporation. Or even a government. It’s more than third of NASA’s annual budget.

A lot of the media have made fun of Gingrich for this plan. The irony is they’re doing it for the wrong reason. A Moon base is being likened to science fiction, just some silly fluff. But that’s grossly unfair.

Space exploration is an issue that’s important. It’s vital to our nation for a host of reasons, but it is also costly in every sense of the word. If we go, we should go for the right reasons, and we should do it the right way. If we go, we must go to stay. The budget for this can’t be set up on political election cycles, it must be based on the real constraints of engineering and technology, and far more importantly it must be based on a commitment to the future. If we do this, we must invest in the long haul.

Gingrich’s plan does not encompass that idea. Ineptly aimed media ridicule aside, what’s clear is that Gingrich’s speech was long on rhetoric but short on actual substance…

The Gingrich Who Stole The News Cycle | Bad Astronomy | Discover Magazine:

In the post for The Crux I was blunt, but held back my tongue a bit because that isn’t necessarily the venue for me to do otherwise. But here, on my blog, I’ll say this: Gingrich’s words were both transparent and hollow. I knew right away what he was claiming was simply not possible, either financially, technologically, or politically. Take your pick. And it was also clear to me that no matter how you slice it, NASA would get screwed royally if his Moon base plan were implemented, since it would mean billions of dollars moved away from NASA projects to finance this. I started digging deeper to see if my first reaction was wrong, and all I found showed I was righter than I first thought. Every way you try to do it, his plan would destroy NASA. And I’m not exaggerating; the amount of money we’re talking about taking away from NASA projects to fund a base his way would leave everything else in NASA facing cancellation. It’s really that simple.

Neal Stephenson discusses America's"Innovation Starvation"

This is a very good essay by a writer I enjoy alot.  His novel Anathem is one of my favorite books ever.  It is the first novel I ever read where, as soon as I finished it, I turned back to the first page and started in again...  He is worth listening to.

Found this one via Brad on Facebook.  Thanks!

Innovation Starvation | World Policy Institute - johniac's posterous:


"I worry that our inability to match the achievements of the 1960s space program might be symptomatic of a general failure of our society to get big things done. My parents and grandparents witnessed the creation of the airplane, the automobile, nuclear energy, and the computer to name only a few. Scientists and engineers who came of age during the first half of the 20th century could look forward to building things that would solve age-old problems, transform the landscape, build the economy, and provide jobs for the burgeoning middle class that was the basis for our stable democracy.
...


The imperative to develop new technologies and implement them on a heroic scale no longer seems like the childish preoccupation of a few nerds with slide rules. It’s the only way for the human race to escape from its current predicaments. Too bad we’ve forgotten how to do it.
...


“You’re the ones who’ve been slacking off!” proclaims Michael Crow, president of Arizona State University (and one of the other speakers at Future Tense). He refers, of course, to SF writers. The scientists and engineers, he seems to be saying, are ready and looking for things to do. Time for the SF writers to start pulling their weight and supplying big visions that make sense. Hence the Hieroglyph project, an effort to produce an anthology of new SF that will be in some ways a conscious throwback to the practical techno-optimism of the Golden Age.
...



China is frequently cited as a country now executing on Big Stuff, and there’s no doubt they are constructing dams, high-speed rail systems, and rockets at an extraordinary clip. But those are not fundamentally innovative. Their space program, like all other countries’ (including our own), is just parroting work that was done 50 years ago by the Soviets and the Americans. A truly innovative program would involve taking risks (and accepting failures) to pioneer some of the alternative space launch technologies that have been advanced by researchers all over the world during the decades dominated by rockets.
...


But to grasp just how far our current mindset is from being able to attempt innovation on such a scale, consider the fate of the space shuttle’s external tanks [ETs]. Dwarfing the vehicle itself, the ET was the largest and most prominent feature of the space shuttle as it stood on the pad. It remained attached to the shuttle—or perhaps it makes as much sense to say that the shuttle remained attached to it—long after the two strap-on boosters had fallen away. The ET and the shuttle remained connected all the way out of the atmosphere and into space. Only after the system had attained orbital velocity was the tank jettisoned and allowed to fall into the atmosphere, where it was destroyed on re-entry.


At a modest marginal cost, the ETs could have been kept in orbit indefinitely. The mass of the ET at separation, including residual propellants, was about twice that of the largest possible Shuttle payload. Not destroying them would have roughly tripled the total mass launched into orbit by the Shuttle. ETs could have been connected to build units that would have humbled today’s International Space Station. The residual oxygen and hydrogen sloshing around in them could have been combined to generate electricity and produce tons of water, a commodity that is vastly expensive and desirable in space. But in spite of hard work and passionate advocacy by space experts who wished to see the tanks put to use, NASA—for reasons both technical and political—sent each of them to fiery destruction in the atmosphere. Viewed as a parable, it has much to tell us about the difficulties of innovating in other spheres.
...


Innovation can’t happen without accepting the risk that it might fail. The vast and radical innovations of the mid-20th century took place in a world that, in retrospect, looks insanely dangerous and unstable. Possible outcomes that the modern mind identifies as serious risks might not have been taken seriously—supposing they were noticed at all—by people habituated to the Depression, the World Wars, and the Cold War, in times when seat belts, antibiotics, and many vaccines did not exist. Competition between the Western democracies and the communist powers obliged the former to push their scientists and engineers to the limits of what they could imagine and supplied a sort of safety net in the event that their initial efforts did not pay off. A grizzled NASA veteran once told me that the Apollo moon landings were communism’s greatest achievement."

What do Republicans have against science anyway?

Okay.  I got sucked in by another headline.  Still transferring files, though, so nothing better to do EXCEPT for getting out and enjoying the gorgeous weather!  Probably the last warm day of the fall, so I am keeping this short.  We've got nothing but drizzle and gloom on the horizon for the next ten days.

Erasing false balance: the right is more antiscience than the left | Bad Astronomy | Discover Magazine"I write quite a bit about how rabidly antiscience the political right in the US has become. From the attacks on science by the Bush Administration (and Newt Gingrich before that) to the political litmus test of needing to denounce evolution and global warming if you’re a candidate, the Republican party has planted its flag firmly in the ground of nonsense. At the bottom of this article is a section called Related Posts that has links to just a handful of the copious examples of this outrageous behavior.

They have also become masters at spinning this, going on the attack against science they don’t like and using the media to sow doubt. One of the most aggravating of these tactics is the one of false equivalency. For example, in a post I might lambaste yet another Republican candidate saying creationism should be taught in schools, and someone in the comments will say, "Well, people on the left are antiscience as well!"

...
And that’s why you need to read an article by my friend Chris Mooney, "Unequivocal: Today’s Right is Overwhelmingly More Anti-Science Than Today’s Left". He lays out just how big this problem is, why the right has gone this way, and why they have solidarity among their candidates.
_______________________________________________________________________________
Chris Mooney | Unequivocal: Today’s Right is Overwhelmingly More Anti-Science Than Today's Left"Last week, I took to task a really poor USA Today op-ed making the following claim:
"In short, for every anti-science Republican that exists, there is at least one anti-science Democrat. Neither party has a monopoly on scientific illiteracy. Indeed, ignorance has reached epidemic proportions inside the Beltway."

I accused the author, Alex Berezow, of constructing a false equivalence between right and left wing science abuse. The latter does occur sometimes, and I’ve given many examples (ionizing radiation risks, vaccines, GMOs, etc). But it has relatively little mainstream influence today—and can hardly compare with the sweeping denial of huge bodies of knowledge (e.g., all climate science, all evolutionary science) that we see on the right."


'via Blog this'

Here is the quote Plait pulled from Mooney's article:  "The chief reason the political right is anti-science is because it contains the Christian Right (and Tea Party, which is kind of the same thing). There is no force in American politics generating anywhere near so much unreality, in science or in other spheres, as this one. It is not just evolution, or the age of the Earth… When it comes to science, it is also anything having anything to do with abortion, reproductive health, and sexuality. Moreover, we are talking here about the willful advancement of dangerous falsehoods, and the clinging to them in the face of all evidence and refutation—because this is about unwavering certainty, and ultimately, about faith."

Full disclosure: I have yet to read the Mooney article.  See note above about the weather.  But I will.

Story Musgrave kicks ass: Thoughts on NASA's lack of vision

10 Questions with Story Musgrave - TIME:

The best of...

"Obama has no plans. Neither has NASA Washington. They don't have the courage. NASA should create a great vision, communicate it artistically and then ask Congress to execute that."

When asked what NASA's goals should be: "To explore farther out. You need to combine your robotics program with the human programs. You go out there with robots. They mine materials, they manufacture, and they assemble a habitat for humans. That's the most reliable and lowest-cost way to get humans out there. Voyager has now been to four planets. For what the space station costs, we could have had 400 Voyagers. If we'd gone that way, today we would have had 100 satellites sending data back to Earth. That's what we gave up by not having the courage to leap off and go further."

One small step for China, one impossible step for America: Falling behind in space

I told myself I wouldn't get distracted with these little posts today, but this story gets to me. Hooray for China! Now, why the hell can't the U. S. figure it out.

This nails it, for me... "It's not driven so much by science, but by the desire to develop new technologies."  And what can we do with new technologies?  Sell them.  And what does product development and the manufacturing and marketing of new technologies do for a struggling economy?  These things create jobs!

Oh yeah, and there is that whole optimism and hope thing too.

Sure, it could be said that right now they are only repeating steps that NASA took 30 years ago.  But we've, pretty much been sitting on our asses for 20 years, so they are not that far behind overall and right now, bottom line, they can put people in space and we cannot.  They are ahead and they win, for now, at least.

In a related post to follow, I think Story Musgrave does a great job putting words to many of my own concerns about the current state of the U. S. space program.

BBC News - Rocket launches Chinese space lab
"China is investing billions of dollars in its space programme. It has a strong space science effort under way, with two orbiting satellites having already been launched to the Moon. A third mission is expected to put a rover on the lunar surface. The Asian country is also deploying its own satellite-navigation system known as BeiDou, or Compass.

Bigger rockets are coming, too. The Long March 5 will be capable of putting more than 20 tonnes in a low-Earth orbit. This lifting muscle, again, will be necessary for the construction of a space station.

"There are loads of ideas floating around, and they're serious about implementing them," said UK space scientist John Zarnecki, who is a visiting professor at Beihang University, the new name for the Beijing University of Aeronautics and Astronautics.

"There's a sense of great optimism. It's not driven so much by science, but by the desire to develop new technologies. The money is there, although it's not limitless. And they're taking it step by step," he told BBC News."
