I know I am not at my blogging best when I just write, “hey, look at these spectacular images!” But…look at these spectacular images!
An image-of-the-day gadget on my iGoogle home page showed me this picture, which I subsequently spent about a half hour trying to locate at a primary-source web site. It is wicked cool.
Possible Cyclic Bedding in Arabia Terra (HiRISE/MRO)
Click to go to this image’s description page on the University of Arizona HiRISE site. (Be sure to bookmark the 2560×1600 wallpaper version!!!)
I really want to know how these terraced buttes got to be the way they are…it looks like they must have been eroded in stages, with each layer from the top getting peeled back successively, but somehow the individual layers hold together – those are some pretty steep walls. I can see in the southwestern portion of this image that some of the terrace walls are eroding away in chunks; there are a couple good fallen boulders over there. The layers might be some kind of sandstone, because they haven’t eroded away in lots of rocks and boulders, so they don’t seem very friable, but there’s obviously a lot of source material for dunes in this area so the butte walls might be getting ground down into very small grains. I’m not sure what the fluvial history of Arabia Terra is – on Earth, that would be bound to play an important role in creating landforms like this.
I also really love the expression of the more recent aeolian features in this area. Looks like there are prevailing north-south winds on the east side of this image (I’m going to say the wind blows to the north because the north sides of the dunes look more like slip faces to me), but from the east-moving dunes in the terraced valley-like feature at center bottom and the east-west oriented ripples on the larger dune field, the winds are apparently going in rather circuitous routes around these buttes. There are also some confusingly-oriented dunes and ripples in the southwest portion of this image, probably from the wind winding around all the rocky towers. (In my mind, I can hear it whistling.)
Looks like the valley from which the east-going dunes have traveled is an exposed outcrop of one of the terrace layers. This image can resolve objects less than a meter in size, so the various crisscrossing dark lines in the light-toned outcrop might be joints or something.
Anyway, this is not a new image and I haven’t studied or researched this stuff…I just saw it today and wrote a little stream of consciousness of geological ideas. I just think this image looks beautiful and I want to send some rovers/people there. Any planetary science guys want to comment?
Last, and just for grins, here are some goodies I turned up in my search for that image on the UA HiRISE site. Here we have some dramatic contrast between dunes and some lighter, rockier topographically high areas:
Pitted Layers Northeast of Hellas Region
Here’s some great layer exposures around some hills – and if you zoom into the large version of this one, you can find some wild and interesting ripple patterns:
I was very encouraged to read that Sen. Bill Nelson (D-FL) expressed some thoughts on the new NASA budget this past week that agrees pretty well with my own view. I’ve generally been worried about the Senators and Representatives from Florida, Alabama, and Texas; since I am very much a proponent of the new NASA programs, I don’t want to see politicians trying to drag out the generally defunct Constellation program just to get some pork for their districts.
Some of Sen. Nelson’s comments:
“I think they made two tactical mistakes that gave everybody the wrong impression,” the Florida Democrat said. “The first one is that the president didn’t set what the goal is, and everybody knows the goal and that’s to go to Mars.
“The second mistake was that they said they are canceling the Constellation program. That sounds like they were canceling the manned (spaceflight) program, when in the same breath he said we’re doing the research and development for a heavy lift vehicle, and they were putting all their eggs in the same basket of getting to the space station with the commercial boys.”
The most frustrating thing to me about the general space-blogger explosion in response to the new NASA budget and programs is that they all seem to have been screaming, “Obama cancelled the manned space program!” That has never been true; he cancelled the already-way-behind-Constellation program. Cancelling the human spaceflight program would look something more like erasing NASA’s Exploration Systems and Space Operations Mission Directorates. ESMD is, in fact, getting the large bulk of the new NASA money, and it’s earmarked specifically for new human space programs and technology. I have even seen news reports that talk about the NASA “budget cut,” when in fact the budget is increasing by a phenomenal $6 billion in the next five years.
What gives? Why do all the commentators think that what’s going on is the exact opposite of what’s actually happening? It could just be the people at Marshall SFC and the fans of Mike Griffin (who frequently pontificates that CxP’s thrown-together-knee-jerk-Columbia-reaction approach is the best and only way to get into space) don’t want to see Constellation’s vehicles go, but that is hard to understand given how far behind schedule Ares I is, how Ares V and Altair don’t exist yet, and how Orion keeps shrinking in capacity and capability. They’re also not everybody in the space community…and I’d expect the rest to be excited about the expanded budget and the new mandate for NASA to go ahead and put modern technologies on their vehicles, instead of sticking to Shuttle-era (that’s the 70’s, folks) stuff. I think Sen. Nelson hit the nail on the head – most of the media have conflated “Constellation Program” with “Human Space Program,” and the lack of an explicitly articulated space goal direct from the President is hurting right now. NASA Administrator Maj Gen Charlie Bolden clearly thinks that the goal is to get people to Mars by about 2030, and President Obama even asked, in his call to ISS astronauts last week, what it would take to get to Mars and beyond.
So I think President Obama desperately needs to give a Space Address, in which he articulates The Goal and expresses American spaceflight ambitions in a way that deals with the issues that Sen. Nelson identified. I think I know, from the budget documents, Bolden’s remarks, and what little we’ve heard from the White House, what would be in this address (again, see my post “NASA, unleashed!“). So, here’s what I think he should say. Everything here is factually accurate, based on the budget numbers and Bolden’s statements. The dramatic difference is that it leaves no ambiguity as to the positive position of our human space program. Obama could give this speech, or something like it, tomorrow. And he should!

“Mike, if you’re CapCommin’ and you’re lookin’ for folks and you can’t find ’em…they’re probably in here.”
That was a radio call from the STS-130 crew to Mission Control in Houston from early on Wednesday, after all seven windows in the ISS Cupola were opened for the very first time. I have been watching NASA TV and trawling their multimedia galleries all the time I’ve been at my desk today…the views out the Cupola – of Earth, the Moon, the Station, and the Shuttle – are simply spectacular. Here is a small selection of the currently available images, available here. (I can’t wait till they release some of the photos looking out at the Shuttle cargo bay and the Soyuz spacecraft on the ISS exterior. Future robot arm work is also going to look amazing.)

I am reluctant to bump “Conference” down on my front page with this can of worms, especially now that my readership has been on the up-and-up, but hey, it’s my blog….
Yesterday I made the mistake of trolling around the New York Times web site for a few minutes between a lunch meeting and getting back to work. It was a mistake because I discovered this magazine article on the influence of religion in textbook revisions. It caught my attention with its headline, but it’s not really about how Christian the American Founding Fathers were. It’s about how Christian the Texas state school board thinks they were.
It’s a long article, and it covers a lot of ground. And I find a lot of it, honestly, terrifying.
I’m not just talking about the despicable attempts to get Christian creationism into science classrooms. (Side notes on semantics: “intelligent design” is a form of creationism, so I will not distinguish between the two; also, I will generally use the word “creationism” as a shorthand for “Christian creationism” – a necessary distinction, as there are hundreds of religions, each with their own creation story, to choose from.) Nor am I talking about the insidious efforts to insert the beliefs and practices of specific Christian sects into our government. I am talking about the repeated references to concepts like manifest destiny – the idea that American history has been guided by divine providence, that westward expansion was an effort to bring the One True Religion to the inferior heathen natives, that God has chosen America for divine purpose. It’s the divine right of kings all over again. And it’s the very reason why we have the First Amendment. A lot of that article made me so angry that I couldn’t do any useful work for about half an hour. Continue reading terrifying influences on school boards→
Cook the onions, peppers, and carrots in a pan over medium heat until the onions start to turn translucent. Throw in the ham and let that cook for a bit. At this point, I put some water on to boil for the pasta. I then added:
about two teaspoons chopped garlic (though I would have liked sliced fresh garlic)
about one to one and a half tablespoons parmesan cheese
a bunch of basil
some crushed red pepper
some oregano
a dash of paprika
Cook that while the water boils. When its time to put the pasta in, throw it in the water and then pour some white cooking wine over the veggies and ham. Turn the heat down to low and simmer until the pasta is done. (I left mine a little al dente.) Drain the pasta, then combine everything, cover it, and shake it all up.
or, The “Apollo on Steroids” Critics Have Their Way
or, President Obama Comes Through On Space
I am simply thrilled at the prospects offered by the NASA budget released earlier today. In that budget, President Obama directed that NASA’s mission shift in scope in a dramatic way – a new paradigm, as all the media proclaim. That paradigm is this: NASA is going to stick its neck out. The space exploration business has grown to become incredibly risk-averse. NASA is now going to start experimenting more, trying new technologies, pushing the envelope, and playing with new strategies while leaving the more conservative aspects of spaceflight to others. NASA is going to lead while others follow. This ends a decades-long effort in which NASA was, essentially, playing catch-up with itself.
Pre-State of the Union buzz is that NASA’s Constellation program is dead.
Now, I haven’t really seen the White House rationale for this, but I suspect it goes something like this: “This country is in a pretty crappy economy right now. We’re bogged down with health care policy in Congress. And global climate change will be a more pressing problem in the future. We don’t have the time, money, or resources to devote to something like space exploration that doesn’t return any direct benefits.”
If you’ve been reading my blog since my time at NASA last summer, you know that I am a big fan of manned space exploration, but not necessarily a fan of the current Constellation architecture. I’m fine with seeing Constellation go, but only if we replace it with something gutsier. So I am not okay with axing Constellation and flatlining NASA’s budget. (Though Constellation was pretty much crippled in the first place by the “do it on the existing budget!” directive in 2004.)
The argument against NASA will likely be one of limited resources and the perception that space exploration doesn’t return anything for the average US citizen. As a counter, let’s start writing the White House and our legislators in the Senate and House, and ask them which terrestrial problems can NASA solve for us? The answer is a laundry list – and a compelling one, just off the top of my head!
Want to grow the US economy and create jobs?
— Give NASA a strong mandate and plenty of resources!
Funding NASA is one of the very few sure-fire ways for this country to glean direct economic benefits. For every $1 that the United States government puts into NASA, the US economy grows by as much as $8. (One source here). This makes it one of – if not the – most effective ways for the federal government to have a positive effect on the economy. That’s a gain of 800%. Compare that to the ambiguous and uncertain economic growth from bailouts, tax cuts for the richest 2%, two wars, unspent stimulus funds, or Congressional shenanigans. NASA creates high-tech jobs, administrative jobs, IT jobs, engineering jobs, research jobs, custodial jobs, manufacturing jobs, analysis jobs. NASA creates technologies, hardware, and software, and puts out contracts for the development of more technologies, hardware, and software. Money going to NASA boosts the economy of every state in the union, some by hundreds of millions – or even billions – of dollars.
Economic growth by state from federal NASA funding (click for full size)
NASA can best provide these economic benefits if it has an ambitious, driving goal – pushing it to turn out as much of a return on the investment as it can – and sufficient resources to pull it off. If it’s the economy we’re worried about, we should be afraid of not funding NASA enough!
Want to keep this country competitive in technological development and scientific progress?
— Fund NASA!
The White House web site recognizes that “the United States is losing its scientific dominance.” Are iPod apps and Twitter really going to carry the tech sector of the US economy in the future? Especially when we are exporting a lot of tech jobs and highly educated workers to other countries? If we want to secure our national future, we need to make sure that we produce plenty of high-powered brains in our own country, and that we work on the latest in science and technology in the research labs and R&D centers available to us. Down the line, if Americans stop caring about science and technology, we are going to be producing smaller quantities and lower quality goods and services. Our development will stagnate when compared to other countries. We will have to look abroad for solutions. Even if that’s not a bad thing outright, why wouldn’t we want high-tech developments and cutting-edge science produced close to home?
We can only derive so much benefit from all the MBAs and lawyers we churn out. But technological and scientific fields develop whole new markets and whole new disciplines that we can use to create better products, better services, better knowledge, and a better society. Remember that when President Kennedy directed NASA to land on the Moon, we had a grand total of 15 minutes of human spaceflight experience. New industries, spun off by fields from specialized materials science to computer technology, that had not even been conceived yet had to be invented. The very foundations of the US manufacturing industry had to be advanced forward a decade to meet the tolerances required for the Apollo vehicles. Imagine what could come out of a similar program today!
NASA is a leading agency in funding both basic science research and technological development. The conclusions from this research percolate into the biotech, electronics, computer, aviation, communications, materials, chemical, defense, and medical industries – just to name a few! The science funding goes to universities and research labs all over America. Technologies developed in the course of pursuing the space program find their way into cars, airplanes, traffic control systems, manufacturing, construction, the food services industry, and even the average American home. If that money keeps flowing, those industries keep growing – and new industries sprout up!
Want to keep the next generation interested in science and technology, so we – and they – invest in their education?
— Give NASA an exciting mission and the money to pull it off!
President Obama has made appreciative statements in the past about the role NASA plays in inspiring American youth to pursue higher education, especially in challenging scientific and technical fields. This must continue. We cannot let children think of science and engineering as the sole domain of nerds and geeks, unpopular kids or unrelatable kids. For the US to be competitive in science and engineering, we need scientists and engineers. That means we must have children who develop and maintain an interest in science and engineering. So we need to make science and engineering, and education in those fields, popular. Fun. Invigorating. Sexy.
But NASA can’t simply “inspire the youth” just by its mere existence. It needs to be in the news. In the news, doing cool things. In the news, doing cool things, constantly. For that, NASA needs a really high-profile, risky-yet-achievable, demanding, sense-of-surmounting-the-impossible mission. As if this nation had dedicated itself to a goal, before this decade is out, of something on par with landing a man on the Moon and returning him safely to the Earth. Something that captivates a youth with an Internet-induced, ever-shrinking attention span. I propose establishing a permanently crewed base on Mars within the next 15 years, by 2025. Such a mission will not only keep the young scientists and engineers of our nation rooting for the space program, and interested in the space program, while they are learning – it will also give them something productive to work on when they finish! NASA is both a means and an end, but only if it has sufficient resources and a mission far more ambitious than the 2004 Vision for Space Exploration.
Want to find ways to feed the hungry?
— Tell NASA to put a permanently crewed base on Mars!
If we try to establish a self-sustaining colony on the Moon or Mars, we need to feed the crew. And if we go for Mars, a self-sustaining base is pretty much a requirement to make the launches feasible. The astronauts would not be able to rely on regular resupply missions.
This means taking what we know about how things live and grow, and finding a way to develop food sources in a space outpost. We would have to leverage everything we know about hydroponics, algae growth, genetic engineering of bacteria, nutrition – the alchemy of turning raw materials into nutritious, palatable food for humans. And since launches to Mars would have severe mass limits, all this will have to be packed into as lightweight and small a package as possible.
Once developed, those technologies would be perfect for taking to the Third World, to the deserts, to impoverished nations and soup kitchens on Earth. We could solve global hunger once and for all, by finding ways to provide families with self-sufficient food-generating equipment. The kind of equipment that comes from NASA ingenuity and NASA money – but it will only do so if the government directs NASA to tackle the problem!
Want to get medical care to as many people as possible in poor, remote countries with little infrastructure?
— Send NASA astronauts to Mars!
If we send astronauts to Mars, they are going to be completely out of reach of medical care. The nearest emergency room will be – at minimum – 45 million miles and half a year away. The Mars base crew are going to have to take care of themselves. This means that, not only is at least one of them going to have to be an ER surgeon or something, but they are going to need medical equipment. Not just any medical equipment, either; ultra-rugged equipment that functions on little to no power with near 100% reliability. Equipment that gives fast, comprehensive test results. Equipment that is easy to use and understand. Equipment that is, or folds up to be, very small and ultraportable. You know – tricorders.
The Mars base is also going to need treatments. Treatments that are easy to administer. Patches, drugs, capsules, ultra-miniaturized subcutaneous infusion pumps, and the like. But again, getting things to Mars requires that they be small and low-mass – five years’ supply of daily vitamins for a dozen or so astronauts would hardly fit the bill! So, they are going to need rugged, reliable equipment to manufacture those drugs on Mars with super-limited resources.
Imagine if Doctors Without Borders could get their hands on all that. Or the Red Cross. Or the Peace Corps. They could…but only if we tell NASA to go to Mars and give it the means to do so!
Want to solve global climate change?
— Tell NASA to keep people permanently in space!
Yeah, that’s right – I didn’t say “mitigate” or “delay.” I said solve.
NASA drives innovation in batteries, photovoltaic cells, Stirling converters, fuel cells, and nuclear power. NASA has to squeeze every last drop of electrical power out of every battery on every spacecraft. NASA has to build their electronics to take meager power supplies.
Crewed spacecraft are closed environments that must support human life. They have to recycle, to reuse, to be careful what they bring in and out. They have limited supplies, limited fuel, limited electrical power, and they must accomplish ambitious science and exploration goals.
Send astronauts to Mars, and they will have to make more use of the scarce resources of the Red Planet than even Space Station astronauts do on ISS, because they will be so far from assistance. They are going to have to maximize what they can do for any input of solar power or raw material. Everything that comes from Earth is going to be incredibly precious, and will have to stretch out its useful lifetime for months or years. The astronauts are going to have to recycle their air. And they’re not going to be able to rely on taking their equipment to the shop every few months or replacing it every few years – it’s all got to work reliably for decades.
Those high-efficiency solar cells, low-power electronics, extreme-reliability equipment, 100% recyclable materials, CO2 scrubbers and chemical recyclers are sure going to come in handy for replacing coal and oil here on Earth.
So let’s solve some problems here on the ground. Let’s go out into space!
He’s my Senator now, and I will accept that. But it also means I get to write him letters. I will send this again to his Senate address once his official Senate contact page is up and running.

Subject: health reform
—
Dear Senator-Elect Brown,
I am writing to remind you that you were elected by the citizens of the state of Massachusetts, not by the national Republican Party or by the health insurance industry.
I did not vote for you in this election, in large part because I viewed a vote for you as a vote against my own life. Your campaign revolved around a pledge to vote against any Democratic reform of this country’s corrupt and failing health care system, without providing any specific alternative proposals. I have very strong feelings about the issue of health care because I have Type 1, or insulin-dependent, diabetes.
Type 1 diabetes does not result from any lifestyle choices, risky behaviors, or unhealthy habits. The exact causes of diabetes are still unknown. When I was three years old, my parents had to take me to the hospital for a weeklong stay, at which point the doctors diagnosed me with this chronic disease. My first concrete memories are from that hospital. Ever since then, I have had to inject myself with insulin and perform blood tests. I now wear an insulin pump which is constantly connected to my body, and do about ten blood tests every day, just to stay alive. I pay hundreds of dollars every month to live with this condition – and that is with health insurance!
Fortunately, and thanks to the late Senator Edward Kennedy, there is a federal law that prohibits insurance companies from rejecting patients with Type 1 diabetes. However, that doesn’t stop corporations from jacking up their rates so much as to be prohibitively expensive for someone like myself. Under our current health care system, unless I encounter a peculiarly gracious insurer, it is most likely that I must rely on my employer to provide me with health care. If I ever lose my job in the future, and have to pay for health insurance on my own, it’s quite possible that I will not be able to afford insurance. And not being able to pay the high cost of my ongoing diabetes care would put my life in jeopardy. This is not a free-market issue of supply meeting demand; I have no choice. I need good health care in order to live, but health insurers constantly raise their costs and charge a premium for patients with chronic conditions like diabetes.
The most medically and financially effective health care for me would involve a reform of the current inferior American system, preferably with a public insurance option. In fact, many reputable impartial studies indicate that a public option would be the most cost-effective way to provide health care to all Americans, even those who obtain private insurance plans, and would reduce the amount our national government spends on health care. That makes a public option both morally right and financially responsible.
I strongly urge you to be an independent voice in the Senate, to carefully analyze your votes, and to consider what is moral, fiscally responsible, and in the best interests of your constituents – like myself. Do not just vote “no” to any and all proposals from members of the Democratic Party, simply because that is what the national Republican Party or insurance-industry lobbyists want you to do. Keep your state and the individuals in it in mind. Do not make shortsighted decisions based on whether or not taxes will go up – especially if health-care premiums would decrease by a larger amount, lowering total costs.
I fear that my pleas will be falling on deaf ears, since you campaigned in Massachusetts on a platform built around refusing Democrat-proposed health care reform. If it is too far at odds with your own principles that you consider a “no” vote and its implications for your constituents very carefully before you cast it, then I strongly suggest that you instead offer your own counterproposal for health care reform. That proposal should involve specific plans to expand health care coverage, lower total health care costs for the public, and lower total health care costs for the government. I have been unable to find any such specific counterproposals in your campaign materials.
I ask you to honor the memory of the man whose Senate seat you will hold, and consider the needs of your constituents. Don’t let petty party vindictiveness or big-industry lobbying dictate your votes. We are in this situation together – Bay Staters, diabetic patients, Senators, Democrats, Republicans, and the President of the United States. We all need a solution. I hope you will work constructively with Senate Democrats and will not disappoint us.
Sincerely,
Joseph Shoer

Before “Avatar,” I’d seen a couple of movies in 3D and had not really been impressed with what the extra five bucks got me. Up until that point there was really only a single scene in a single movie in which I thought the 3D effect actually added anything to my experience. (It’s the shot in Pixar’s “Up” in which the house floats in front of the sunset…all the colors of the sunset shine through all the colors of the balloons, each balloon is a nice round object, and the whole collection of balloons looks three-dimensional. Beautiful.) For the most part, though, I tend not even to notice that a movie is 3D unless I’m specifically looking for the three-dimensionality – if it’s a good movie, the story and characters ought to hold my attention more than that – or if the filmmakers try some cheesy, gimmicky, amusement-park-style 3D “popping” effects, a la “Beowulf.”
“Avatar” changed my mind a little, in that many more of the scenes looked so damn cool in 3D. But the more I thought about it, the more I became convinced that while the 3D experience was pretty neat, if I go see “Avatar” any more it will be in 2D, because it really didn’t add that much to the movie. The forest creatures and sweeping panoramas will look just as good projected in 2D. The only aspects of that movie that would miss out are the holographic computer displays, and those aren’t really that important.
In fact, I think that Hollywood ought to just abandon this 3D movie kick. It’s not that I get a headache or think that cool things can’t possibly be done in 3D. It’s that even when filmmakers do the cool things, it adds so little to a movie that I’m definitely not inclined to shell out for a 50% surcharge on a ticket. Here’s why…
