Allison Davies has a spacesuit, and she’s not waiting for a call from NASA for a chance to wear it. In fact, she designed it herself to better haunt her sci-fi vistas. Davies’s photography is an amalgam of self-portrait, landscape, and science spoofing satire. These images suggest Davies has traveled to the far reaches of the solar system, or perhaps to the future, in order to conduct urgent but entirely mysterious experiments. All your reasonable questions—where, what and why?—will remain purposefully unanswered. Davies’s book, “Outerland”, edited by Richard Renaldi, was launched on Earth Day by Charles Lane Press.

Human-Neanderthal Mating Left Its Mark in the Human Genome | 80beats

NeanderthalEver since anthropologists figured out that early humans and Neanderthals coexisted for a span of prehistory, they’ve wondered–did the two species, you know, make friends? Now a fascinating new genetics study reveals that Homo sapiens and Neanderthals did indeed interbreed, and the evidence is still to be found in the human genome.

Researchers from Germany’s Max Planck Institute for Evolutionary Anthropology first sequenced the entire Neanderthal genome from powdered bone fragments found in Europe and dating from 40,000 years ago–a marvelous accomplishment in itself. Then, they compared the Neanderthal genome to that of five modern humans, including Africans, Europeans, and Asians. The researchers found that between 1 percent and 4 percent of the DNA in modern Europeans and Asians was inherited from Neanderthals, which suggests that the interbreeding took place after the first groups of humans left Africa.

Anthropologists have long speculated that early humans may have mated with Neanderthals, but the latest study provides the strongest evidence so far, suggesting that such encounters took place around 60,000 years ago in the Fertile Crescent region of the Middle East [The Guardian].

The study, published in Science and made available to the public for free, opens up new areas for research. Geneticists will now probe the function of the Neanderthal genes that humans have hung on to, and can also look for human genes that may have given us a competitive edge over Neanderthals.

Erik Trinkaus, an anthropologist at Washington University in St. Louis, who has long argued that Neanderthals contributed to the human genome, welcomed the study, commenting that now researchers “can get on to other things than who was having sex with who in the Pleistocene” [AP].

For a much deeper dive into these issues, head to Carl Zimmer’s post at The Loom and Razib Khan’s post at Gene Expression.

50 million Neandertals (genetically) | Gene Expression

John Hawks has a very long post up. This part caught my attention:

We don’t really know the answers, but now we have a chance to test hypotheses about ancient population size and expansion in Neandertals. My point at the moment is only this: If today Neandertal genes make up only one percent of the gene pool of the 5 billion people outside Africa, that’s the genetic equivalent of 50 million Neandertals.

As Hawks notes later, this paper comes pretty close to resolving whether Neandertals were of the same species as we moderns, at least using the biological species concept. There were fertile hybrids. That should not be too surprising, a few years ago when the Neandertal introgression story was big I looked into mammalian embryology, and our lineage had to be very special as mammals went for their to be inter-population sterility.

This is not just a science story. Dave Chamberlain observes:

Anyone else notice that the artists depictions of neanderthals have slowly changed from stupid brute monkey men to ruggedly handsome moderns with a protruding brow? Hmmm, I bet they get even more good looking now. Hawks promises all neanderthals all the time, I for one can’t get enough of it.

I think that this will change our perceptions, and “artists’ renderings” quite a bit. A few years ago when it seemed that Neandertals may have been highly depigmented I observed that it was a bit strange that in most depictions they tended to be rather dark and swarthy as Europeans go (most famously in Jean Auel’s work the H. sapiens sapiens were Aryan Übermensch while the Neandertals were small and dark). I think some of the same subconscious dynamic was at play as when Tom Coburn was outraged at the TV nudity of Schindler’s List. Coloured people naked on a National Geographic special is one thing, but white people should be decent! (and please, don’t accuse me of seeing racism where it isn’t. If you know me you know that I’m not super-obsessed with that sort of thing, but I think it’s pretty obvious that there’s a lot of implicit assumptions which go into being a white European, and how one views someone and how they should behave)

Environmental disaster from space | Bad Astronomy

The leaking oil pipeline in the Gulf of Mexico is gearing up to be the worst environmental disaster in American history. It’s still second to the Exxon Valdez incident, but at this rate it will pass the Alaska spill soon. Reading about this is breaking my heart, and angering me a lot. It’s difficult to express in words how truly awful this is… so maybe a picture will help.

aqua_oilleak

This image, taken by NASA’s Aqua satellite, shows the slick as it was on May 4 — well over 50 km (30 miles) long and growing. An earlier image shows the slick when it was half that size, just three days earlier. "Alarming" is a terribly understated word to say the least. Against the natural browns and greens of the land, and the steely blue of the Gulf waters, the gray of the oil is threatening, menacing, sick. It reminds me of The Black Thing from A Wrinkle In Time.

Efforts are underway to mitigate the leak — more on that in a later post — but I want to point out that these satellite images are useful to those on the ground, so to speak, to track the growth and spread of the oil. The efficacy of space exploration may not spring to mind when contemplating environmental disasters, but it’s there nonetheless.

I have one more thing to add, which is somewhat contrary to my point above. There is an irony here: Some images of the leak from space almost make this disaster look less impacting. Here is a shot taken by astronaut Soichi Noguchi, as the space station flew past the Gulf on May 5:

This picture is actually lovely, which is such a disturbing dichotomy from reality! It’s difficult to see how truly apocalyptic 200,000 gallons a day of crude oil gushing up from the sea floor is when looking at this — and it may get far worse.

I am not implying any deeper meanings to this second image, though you may feel free to take away whatever metaphor you wish. But pictures themselves are only telling us a story. It’s up to us to interpret them, and to extract what useful information we can.


A relevant human space program

In all the debate over who has the best plan for NASA, I think something important has been lost.  Right now, I think destinations and architectures aren’t as important as articulating a coherent vision for a space program relevant to America’s needs and values.

Given the shock that has accompanied the pending Shuttle retirement, the continuation of a Space Station that I doubt most Americans know exists, and the proposed cancellation of the Constellation Program (that I think even fewer Americans really knew about), I think it’s clear that we haven’t done that.  Instead, we have people arguing back and forth over what largely amount to platitudes.  I hear friends and colleagues, who are understandably disenchanted with the political process, wishing aloud that the government would just give us the money to go do what we want and leave us alone.

That’s never going to happen, of course.  Whether civil servant or contractor, all of us involved in NASA’s human space flight endeavors are stewards of the taxpayers’ money.  Members of Congress and the President are the duly elected representatives of those same taxpayers.  Between the Executive and Legislative branches of our political triad, policy is crafted, funded, and executed.  Human space flight is inherently tied to the political process and we fail to bridge the technical and policy worlds at our own peril.

There have been many strategies put forth to try to help NASA better navigate the winds of political change.  Most that I’ve seen propose some mechanism to make it more difficult for politicians to change course mid-stream.  The politicians control the purse strings, so that’s never going to happen, either.

I think the most effective strategy for NASA exists at a much more basic level.  It’s something I always kinda knew in the back of my head, but I didn’t really learn how to start explaining it better until I had the opportunity to serve on the Barrier Analysis Team for JSC’s Inclusion and Innovation Council.  Mark Craig, a NASA veteran and senior executive at SAIC, was one of the mentors for our team and I think I learned more from him than anyone else over that period.

If you keep up with OpenNASA, you’ll know that this isn’t the first time I’ve broached the subject.  I think NASA’s best defense is to design and pursue programs and strategies that are relevant because they contribute to solving America’s strategic problems.

On May 5th, I had the opportunity to listen to Mark discuss this topic in more detail.  He was gracious enough to let me share here on OpenNASA what I took away from his talk.

Since it was presented under the auspices of the JSC Storytelling program, Mark opened up by defining what a “story” is, according to his friend and colleague, Bob Rogers.  A story is ” a deeper level of truth by which we explain the world and our place in it to ourselves.”  (Note: Ask yourself how you explain, honestly, the world and your place in it.  How do you relate that story to other people? We’ll come back to that.)

Mark also explained that he sees relevance as having two parts.  There is the “why” and the “value.”  “Why Relevance” explains our reason for being.  It tells us where we go and what we do.  Mark offered the statements of the Augustine Committee and John Marburger, OSTP Director under President Bush, as examples.  The Augustine Committee said we go into space to expand the human presence in the Solar System, while Marburger stated that our goal was “to advance U.S. scientific, security, and economic interests through a robust space exploration program.”

These statements aren’t necessarily contradictory, but they illustrate different perspectives on the “why” that must be taken into account.

“Value relevance” is defined by Mark as a “critical mass” of benefit delivered to a “critical mass” of stakeholders.  This recognizes that you probably can’t please everyone, but you can and should satisfy enough of your stakeholders to press on.  This form of relevance must actually be experienced by the stakeholders, though.  We can’t just go do something that we think is great and, then, try to sell it to everyone else. Value relevance is fostered through a continual process of research (identify what is important to your stakeholders), creation (make something that meets their needs), delivery (make sure they get it), and self-improvement (evaluate how well you did the last iteration).

This is not just a communications problem.  We’ve labored under the assumption for far too long that we don’t do a good enough job “selling” the space program to the public.  Mark rightly points out that this process of creating value relevance must be built into architectures and designs early on.  The research part is key because we have to meet other people where they are to effectively engage them, both on a technical and emotional level.  One commenter in the audience noted that, in the business world she came from, you have to know your audience or you will fail.

Mark also had a few recommendations and “Red Flags” for us to consider.  First, he advocates the creation of an external guidance and accountability function, similar to the Decadal Survey process, for human space flight.  Having an external group of “thought leaders” in science, industry, art, and culture would provide the outside perspective that we in the human space flight community lack.  This would help keep us from drinking our own bathwater.

NASA would also need its own value management system to engage external marketing experts, employ industry best practices in value management, and document the structure in NASA processes.  This gets back to the point about needing to build value relevance into our system early on.

From his experience as a NASA veteran and consultant to museums, Mark also suggested some areas where we could make a real impact.  For example, the movie Apollo 13 was compelling because it showed, in detail, what the people went through.  NASA TV’s view of Mission Control, by comparison, looks like a security camera.  We have experiences and emotions to share with the public.  Why don’t we?

Mark also believes that we could be doing more in the area of medical research for the benefit of people here on Earth.  My personal opinion is that we have a similar opportunity in the area of energy.  American-owned and operated powersats and miniaturized, passively-safe nuclear power could revolutionize both industry and space exploration while giving us avenues to reduce our dependence on fossil fuels.

Changing our approach to how we build and conduct the space program doesn’t just involve top-down management, though.  Mark also identified what he called “red flags” for us to push back against when we see them.

  1. Don’t just assume change is happening.  Ask how programs are being shaped to bring it about.  Who is in charge? What is the funding and where does it come from?
  2. Ask how something improves sustainability. Changing a vehicle, destination, or program isn’t enough.
  3. In regards to outreach, are we just showing up? Or are we deliberate and thoughtful in our approach so that we listen to what the people we are reaching out to are saying?
  4. “We just need to explain it better.”  Be careful.  It’s a trap to convince ourselves our original idea is right.
  5. “Congress is our customer.”  Be careful.  It’s a trap to blame our missteps on politics.
  6. “The public is our customer.” Be careful.  It’s a trap to abrogate accountability because it’s too nebulous.
  7. “Marketing is illegal.” No, it isn’t. Lobbying and advertising are, but those aren’t all there is to marketing.

I agree with Mark’s argument that we can build human space flight into the fabric of society, if we can build relevance and accountability into the human space flight program.  We just have to remember that this is relevance that is researched, understood, and delivered; not just assumed.

So, with that in mind, I ask you to consider the following questions.

What is the compelling story for the human space program?

How can we make it relevant to America’s needs and values?

How you can be a part of changing the narrative?

The Neandertal Genome & Us | Gene Expression

I’m still digesting the papers on the Neandertals which just came out. You can find them here. If you have questions, please read the papers first. They’re open access, so free to all. There’s a lot to mull over, and I don’t know what I can add right now, but I will note:

1) There’s a lot of stuff that doesn’t have to do with admixture, but focuses on genes where Neandertals and modern humans differ. There is for example an enrichment of differences in genes which relate to skin morphology. But my friends who think that modern human uniqueness can’t be pinned down to changes in SNPs will probably feel even more validated by this paper.

2) The fact that non-Africans as a whole, including Papuans, have Neandertal admixture, presumably from interactions in the Middle East, seem close to falsifying the “two-wave” model of expansion “Out of Africa” which came to prominence in the early aughts. That is, one group of Africans went north through the Middle East, and another swept along the Indian ocean fringe and onto southeast Asia. If there were two waves then they interacted a lot because they both received the same proportion of Neandertal alleles, which makes the idea of two genetically distinct waves a bit useless.
