Or, A Little Mars & Origins of Life History Before Tackling Today’s Space Exploration Debates, Part II
One of the exciting things about blogs is the fact that we can update them with new information, make corrections, add comments. They are not static in time and space like traditional journalism or nonfiction writing.
Yesterday I had an email response from my new scientist friend turned organic cattle rancher, Sherwood Chang, whom I quoted in my previous post (and will be quoting in the next couple of posts). He made a few corrections and additions, which I have added right into the text of the post itself (see below).
I have a Master’s degree in creative nonfiction. Why I chose “creative” nonfiction rather than traditional nonfiction has to do with my respect for creativity itself. One of the reasons that creative nonfiction was established as a genre was in consideration of the need to make the reading of “facts” enjoyable, rather than a dry boring academic, experience. Creative nonfiction allows an author to experiment with style, presentation and content in ways that make the information it contains interesting. Being a new media / multimedia artist as well as author, I also believe that a creative approach to writing about information and facts also allows us writers to present our content more successfully – using new methods to convey information, rather than sticking with traditional dry, emotionless and style-less words and diagrams.
I could have taken the suggestions of Sherwood and simply changed and updated my previous post, but, instead, I went to the text and crossed out the text I was eliminating and typed the new text in bold, so that readers could actually see my process, my interaction with the scientist. To me what is exciting about this is that it brings the words and process itself to life. It makes writing a public process, a shared process. As someone I quoted in an earlier post said, “Blogging is writing out loud.” (I will look up my source later and update this sentence)
Oh, and thank you Sherwood for also recommending two relevant books for us, which I will post on the book page soon, too: “For an historical review and summary of recent (up to 2002) work on the origin of life, I suggest the book, Life’s Origin (2002), ed. J. William Schopf, U. of Ca. Press. A more recent and broader based book is by W. Sullivan and J. Baross, eds.(2007) Planets and Life: The Emerging Science of Astrobiology.”
My next episode on the search for life in space exploration next week. . . .
Or, A Little Mars & Origins of Life History Before Tackling Today’s Space Exploration Debates, Part I
In my post before last I mentioned I’d share some Mars exploration history before moving on to Mars in current events.
In the midst of my interest in the current state of space exploration I coincidentally was offered a ride by a space scientist between my friend Karen’s apartment in Berkeley and my friend Joe’s house in Vallejo last October. I was visiting the Bay Area in order to see and hear the amazing Sixto Rodriguez, who was appearing at Bimbo’s 365 Club in San Francisco.
I’d discovered Sixto was soon to play in San Francisco (my home town) after I saw the documentary about his remarkable life, Searching for Sugarman, in Pasadena. I went home, jumped online, and, in a happy spontaneous act, bought several tickets for his performance. I then called a few friends in the Bay Area to tell them I was coming up for a week visit, and asked them all to join me for the concert. Karen had insisted that I not bother renting a car as I could take BART or hitch rides any where I wanted to go. I saw this as a real adventure, and was later glad I took her advice. One experiences a whole new social world without the “protection and safety” of one’s own vehicle.
Sherwood Chang, the scientist who gave me the lift to Vallejo, is a retired space scientist now living in Northern California and running the largest organic cattle ranch in the state. He spent his previous career as a scientist with NASA ‘s Ames Laboratory in Northern California. I know that scientists David Peat and David Bohm would not have been surprised by what I considered a very happy coincidence (to meet a space scientist on vacation when I am blogging about space), because Peat and Bohm noted that it is of greater interest that we all do not notice more life coincidences given the mathematical likelihood of their abundance.
I hopped into Sherwood’s SUV, buckled up, turned on my GPS as neither of us knew how to get to Joe’s from Karen’s, and asked him, “So. Tell me about your career as a scientist.” He questioned what I wanted to know, and I told him, “Everything.” I also told him that I have read lots of science since I was a very young kid, even though I am professionally a writer and artist, so that he did not have to talk down to me. Sherwood took me at my word, and proceeded to thoroughly entertain me with the most elaborate and compact one hour lecture (about the history of the search for life in space exploration ) I have ever experienced.
This is what I learned:
One way we can begin to understand the history of our universe biosphere is by studying molecular biology. Because the history of living things is stored in the genetic code of all organisms. But if we want a full understanding, we must also glean information from a bunch of other scientific disciplines. Astrophysicists look deep into space, and back in time, and try to figure out how planets formed around stars. Geochemists and Geophysicists help us to understand how planets formed and what the environment is/was like in each of the star systems planets they study. They are all wondering if and when any planets or planetary systems are/were receptive to life or not.
While these scientists are doing their research, mathematicians and computer scientists are busy analyzing the data these scientists come up with, and developing theories based on that data. One can certainly imagine that we are able to understand a great deal more today with the powerful computers at everyone’s disposal for modeling, calculating and analyzing, than we were able to understand when all we had was a roomful of mathematicians sitting around calculating on their own (as recently as WWII to my knowledge) or working with a room-sized computer that had about 100K of memory!
Sherwood began his career in the 1950s as a chemist. Chemists study reactions. And the reactions Sherwood and his buddies were interested in were those that occurred in ancient, primordial, environments on Earth and on other planets in our solar system. If we are going to understand the beginning(s) of life, a great place to start is on the young Earth at the time our planets formed. And the first thing we would need to know, is what was the environment like then, before life appeared. Of course the goal then was to understand when and why life appeared here on Earth, and if it did on other planets as well.
Back in the day (as my college design students are fond of saying) not much was known about primordial (earliest stage of development) environments. Many scientists thought that the early atmosphere of Earth was similar to that of Jupiter. That belief was based on actual science according to my space history travel guide, Sherwood; it was just that Jupiter’s was the only atmosphere they thought relevant to early Earth’s.
So in 1952 at the University of Chicago, two scientists, Stanley Miller and Harold Urey, decided to create chemical reactions that would simulate Jupiter’s atmosphere . . . to be continued
Coincidentally, immediately after my last post – making reference to the importance of Earth protection and our meager atmospheric protective shield, I learned that a Riley Duren would be speaking at JPL on Feb 14 about that very subject. Specifically on global warming and the geoengineering research being conducted to save our planet from it. I am happy to report that Dr. Duren is more supportive of the idea of mitigation than geoengineering (i.e. let’s try to do everything we can to stop, or lighten, this global warming we have started before we resort to the extravagant, and expensive, engineering methods to stop it). Dr. Duren’s lecture would probably win a riffingonbooks award if I were handing them out (maybe I will start!), for he was not afraid to tackle the tough, controversial questions, and he spent considerable time addressing the need for cross-discipline and public participation in the challenges we all face due to global warming. The scientists cannot solve this problem alone, he told us. We need the public, leaders, legislators, physical and social scientists, etc. involved because the work and decisions are so complex as to need the input of everyone. I will write a full post about this lecture and subject after I complete the next few posts on Mars and space exploration.
Will post my next piece about Mars in a day or two. I am just waiting for the scientist I interviewed in northern California to get back to me with the answers to a couple of follow-up questions.
The news media is rife with stories about missions to Mars and to asteroids lately. A great deal of the interest has been spawned by the fact that we have a mission on Mars currently, Curiosity. My guess is that there are also many stories being placed and encouraged by the public relations arms of our various space agencies and by some of the new private space tourist and exploration firms – to drum up more public and political interest.
There are huge questions looming: should we be sending personned explorations to Mars, Jupiter’s moons, asteroids? What do we want to learn about Deep Space? How should the private sector be involved in space missions, and if they are, what kind of oversight should the public and leaders require? Can we learn as much from Earth as we can from traveling in space? What does space travel teach us that simulations cannot? Should we try to establish human colonies on Mars, and if so, why? How much money should we be spending on space exploration? Is space travel for humans really a possibility? What are we actually looking for, trying to accomplish?
Before the public can be expected to participate intelligently in any discussion or debate about where we are headed as Space Explorers, some history is certainly in order. I know it was for me. So I began some rudimentary research in order to make myself a more educated participant in the discussion. One of the greatest disservices that scientists have done to the public, and ultimately to themselves, over the last decades is to have constructed messages telling the public that science is too complicated for their feeble brains. Nonsense.
For as long as I can remember, space travel enthusiasts have compared our need to explore space with the early European exploration of the Americas. With their discovery of new worlds and the fact that the earth was not flat. But, as I have studied space exploration the last months, interviewing scientists, reading up on its history, attending lectures, etc., I have come to believe that this is actually an unworkable analogy. Yes, we have a human need to explore, to understand our world, our universe, our reality. Yes, we have a relentless need to know if we are alone in the universe, or if there are some others like us.
But it may be that humans simply cannot bodily explore the universe because our bodies cannot survive such an exploration. It may be that we can explore our universe more effectively by staying put here on Earth and developing exploration tools and simulations.This may not be as glamorous or exciting as the Space Cowboy scenarios so many have been weaving over the last decades, but that is even more reason why the public needs to be let in on realistic lessons about science if we are going to encourage their continued support of a space exploration something more akin to seated in an armchair and watching on the TV screen.
Thus far my research has taught me that the most important thing we need to do right now is to protect our Earth and the human/animal/life protective atmosphere it houses because we may very well be stuck here! Of course I will keep myself open to alternative ideas as I continue my exploration, but so far everything points in that direction. If we lose the protection of our planet, we won’t be available to explore the universe in the future.
