Searching for origins of life in Yellowstone’s hot springs

April 17, 2007

A few hours ago I posted a notice on satellite studies of the uplifting of a part of the Yellowstone Caldera, and I suggested some (weak) links to how to use it in the classroom. In passing I noted that the volcanic rock site southwest of Yellowstone, the Craters of the Moon National Monument, had been used to show astronauts what the Moon would be like when they landed Apollo missions there.

Yellowstone and especially its volcanic features also provided dramatic insights to the origins of life on Earth, especially the rise of life in hot water. These findings advanced the science we now call astrobiology, or the search for life on other planets.

This evening I stumbled across an interesting feature: A full text of a classic 1978 book on thermophilic life in Yellowstone, explaining in greater detail the research conducted there and its significance in astrobiology and evolution. Thomas D. Brock’s book, Thermophilic microorganisms and life at high temperatures (Springer-Verlag, New York, 1978; 465 pages) is just sitting there, online, for anyone to read. Thermophilic microorganisms, book cover
In this book there is more real science to this one tiny facet of the study of the evolution of life than there is in the entirety of the intelligent design political movement.

I wonder what other gems there may be in that digital collection at the University of Wisconsin.

“Penetration however slight”: More on a good and noble hoax – the U.S.S. Pueblo

March 9, 2007

1968 brought one chunk of bad news after another to Americans. The year seemed to be one long, increasingly bad disaster. In several ways it was the mark of the times between the feel-good, post-war Eisenhower administration and the feel-good-despite-the-Cold-War Reagan administration. 1968 was depressing.

What was so bad? Vietnam manifested itself as a quagmire. Just when Washington politicians predicted an end in sight, Vietcong militia launched a nationwide attack in South Vietnam on the Vietnamese New Year holiday, Tet, at the end of January. Civil rights gains stalled, and civil rights leaders came out in opposition to the Vietnam war. President Johnson fared poorly in the New Hampshire primary election, and eventually dropped out of the race for the presidency (claiming he needed to devote time to making peace in Vietnam). Labor troubles roiled throughout the U.S., including a nasty strike by garbage collectors in Memphis. It didn’t help to settle the strike that the sanitation workers were almost 100% African American, the leadership of Memphis was almost 100% white, and race relations in the city were not so good as they might have been – the strike attracted the efforts of the Southern Christian Leadership Conference, and Martin Luther King, Jr. – who was assassinated there in early April. In response, riots broke out in 150 American cities.

More below the fold, including the key confession to “penetration.” Read the rest of this entry »

Blue Origin brings space exploration back to Texas

January 5, 2007

Texas plateTexas’ regular license plate features a Space Shuttle, some stars and a crescent Moon, but a lot of Texas 8th graders are foggy on just why. I hope kids living near Houston have a better idea, since the Houston Johnson Space Center is in their area. To most kids under the age of 20 in Texas, space exploration is not a part of Texas history. I had one student in class ask why it was that in the movie version of the Apollo 13 story, the astronauts said “Houston, we have a problem.”

The drive to get a private spacecraft into commercial use has at least one company using Texas as a base. Space exploration may once again become a current event item in Texas social studies classes.

Jeff Bezos’ company, Blue Origin, tested their space craft in November, and the tardy news is bustling around the internet — and present in print and broadcast media, too. That the story is so hot on the internet should be a cue to mass media that it’s time to start paying attention.

The company’s test site is in Culberson County, in far west Texas — far away from the giant media markets in San Antonio, Houston and Dallas-Fort Worth. El Paso is the closest major market, and it’s in a different time zone from the rest of the state.

This space exploration group reverses NASA’s Houston-to-Cape Canaveral style of operations — Blue Origin is headquartered in Kent, Washington, closer to Bezos’ Amazon roots.

Blue Origin is hiring engineers, by the way.

Watch that space.

Hall of Fame: Debunking the Moon landing hoax hoax

December 10, 2006

Apollo 14 on the moon - Alan Shepard?

In a classroom discussion of “how do we know what we know” about history, another student brought up the allegations that the National Aeronautics and Space Administration (NASA) faked the manned Moon landings. That makes about a dozen times this year a kid has mentioned this claim (who thinks to start counting these things?). The kid was pretty unshakable in his convictions — after all, he said, how can a flag wave in a vacuum?

I usually mention a couple of things that the fake claimers leave out — that dozens, if not hundreds, of amateur astronomers tracked the astronauts on their way to the Moon, that many people intercepted the radio transmissions from the Moon, that one mission retrieved debris from an earlier unmanned landing, etc. Younger students who lack experience in serious critical thinking have difficulty with these concepts. They also lack the historic background — the last manned Moon landing occurred when their parents were kids, perhaps. They didn’t grow up with NASA launches on television, and the whole world holding its breath to see what wonders would be found in space.

Phil Plait runs a fine blog called Bad Astronomy. Five years ago he got fed up with the Fox Television program claiming the Moon landings were hoaxes, and he made a significant reply that should be in some hall of fame for debunking hoaxes. Since the claim that the Moon landings were hoaxes is, itself, a hoax, I have titled this “Debunking the Moon landing hoax hoax.”

In any case, if you’re wondering about whether the Moon landings were hoaxes, you need to see Phil Plait’s post. Phil writes:

From the very first moment to the very last, the program is loaded with bad thinking, ridiculous suppositions and utterly wrong science. I was able to get a copy of the show in advance, and although I was expecting it to be bad, I was still surprised and how awful it was. I took four pages of notes. I won’t subject you to all of that here; it would take hours to write. I’ll only go over some of the major points of the show, and explain briefly why they are wrong.

Also, consider these chunks of evidence, which Phil does not mention so far as I know:

First, the first Moon landing left a mirror on the surface, off of which Earth-bound astronomers may bounce laser transmissions in order to measure exactly the distance from the Earth to the Moon. Read the rest of this entry »
