Space Shuttle Launch - Systems Go, Fingers Crossed
NASA's Associate Administrator, Bill Gerstenmaier, put it this way: “Even though there are a lot of dimples on the tank, they’re very low mass. It has a slightly higher risk due to the number of repairs. It’s as good — almost — as a regular tank that we would go fly."
COMMENT: I'm not an engineer, and the people working on the Shuttle are among the best engineers you can find on this planet. That said, this decision makes me nervous. I'll be watching June 8 with fingers crossed that all goes well.

Dozens of new mammals - really!
While van Roosmalen is well known as a conservationist and for describing new species of monkeys, his work goes far beyond that. He has, for example, described the largest new mammal to be found since the early 1990s, the Giant peccary Pecari maximus. Awaiting description are a dwarf manatee, a possible new dolphin, another peccary, a tapir, and new species of deer and monkeys (many more monkeys). Most intriguing of all is the black and white jaguar (not a melanistic example of the common jaguar, but a distinct species which Bill Rebsamen so stunningly illustrated for my recent book Shadows of Existence: Discoveries and Speculations in Zoology (on which I corresponded with van Roosmalen during the research phase.)
It's possible, even likely, that some of the many specimens von Roosmalen has or is tracking down will prove to be something less than full species. He has, however, made a gigantic and underappreciated contribution to zoology. He has demonstrated that, as Bernard Heuvelmans, the founder of cryptozoology, once wrote, "The great days of zoology are not done."
Van Roosmalen's new website is a "must see"

R.I.P. - Homer Joe Stewart
Dr. Homer Joe Stewart taught at Caltech and contributed to rocket propulsion and other disciplines at the Jet Propulsion Laboratory (JPL), which he co-founded, for many decades. He had retired from the school in 1980. After WWII, he worked on rocket and missile propulsion systems for the WAC Corporal, Corporal, and Sergeant missiles, among other projects. In 1955, he chaired the Stewart Committee, which, in a controversial decision second-guessed ever since, selected the Navy's Vanguard satellite proposal (based on its potentially greater scientific return) over competing Army and Air Force ideas to become the nation's first satellite program. Stewart encouraged the Army team, headed by Wernher von Braun, to keep working on its idea in case Vanguard faltered. While Vanguard eventually became a significant success, it had a critical failure in a launch attempt shortly after Sputnik 1, and the Army team, in cooperation with JPL, was given the go-ahead to get something up as fast as possible. That project, on which Stewart assisted, became Explorer 1. Homer Joe Stewart was 91.
COMMENT: Erika Lishock and I would have liked to interview Stewart for our book on the first satellites, The First Space Race, but he was already in poor health and was not available. He made major contributions to defense, aerospace engineering, and the exploration of space. We salute a truly great man.

The Megafauna Murder Mystery
Numerous experts have supported the idea that all those megafauna were essentially hunted to extinction. I've always had a problem with the idea that this is the whole answer. Where, in historical times, is one example where we can say with certainty that indigenous people have hunted a an entire ecosystem of large, wide-ranging species to extinction? If all the largest animals in N. America were wiped out, along with their predators, why did Africa (until modern poaching) teem with elephants, rhinos, hippos, and the predators that fed on them? Humans had perhaps 2 million years to spread out and hunt in Africa, but only 13,000 years or so in N. America.
OK, enough editorial comment. Read for yourself why, according to a team led by James Kennett of the University of California, Santa Barbara, it looks likely a celestial body, most probably a comet, had a hand in the mass extinctions. I'm not sure from reading that that I would call it established fact, but it's certainly an intriguing possibility.

All Creatures Great....
Experts with a U.S.-funded wildlife conservation program in war-ravaged Sudan have found a treeless island in the nation’s southern swamps that is home to “hundreds” of elephants. One participant, Tom Catterson, said, "We flew out of a cloud, and there they were. It was like something out of Jurassic Park.” The poachers who have ravaged Sudan’s elephants and other wildlife apparently never knew of this remote spot, whose location is being kept secret.
COMMENT: OK, this episode concerns a chaotic, poor, war-torn nation where travel was difficult and wildlife officers were few. But still… hundreds of elephants living unknown until now? The example will bring smiles, not only to wildlife conservationists, but to cryptozoologists who speculate on what else we might have missed.
...and Small
“Go to the ant, thou sluggard. Consider her ways and be wise.”
The words of King Solomon come to mind amid new research on how army ants move efficiently over terrain which, from an ant’s point of view, is full of holes and other obstacles. The answer: living pothole-fillers. Scott Powell and Nigel Franks of the University of Bristol reported that ants of the species Eciton burchellii fill holes by climbing into them, adjusting their bodies to fit, and letting their sisters march over them. If the hole is too big, several ants will climb in. The behavior observed in Central and South America was duplicated in the laboratory, where ants marching over boards with holes drilled into them essentially took individual action to make the march of the colony more efficient. When the horde has passed, the “filler” ants clamber up and rejoin the march.

Life in the Wedell Sea
Accompanying the article above in The Economist is an editorial discussing just how complex this whole business of describing species really is. Whether a scientists uses morphology, reproductive isolation (aka the Biological Species Concept or BSC) or DNA, classifying and bounding a species remains a fuzzy business.

Yuri's Night celebrates space exploration
High Tech v. Human Error
An oversight in writing procedures for the spacecraft led to its misalignment relative to the Sun and the loss of power to the solar panels. The craft expired when its backup batteries were gone.
On the plus side, the orbiter, launched in 1996, lasted four times as long as expected. NASA managers class the mission as a resounding success no matter how it ended.
The Stuff of Life - Re-created
A new experiment gives a strong, though not conclusive, indication that Earth could indeed have been the crucible of life without cosmic help. A simulated lighting storm in a re-created primordial atmosphere - an experiment first performed in 1953, but now informed by a much better idea of what the planet was like in those days - produced a "soup" of amino acids necessary for life. Chemist Jeffrey Bada, whose team at the Scripps Institution of Oceanography performed the experiment, says, "Maybe we're over-optimistic, but I think this is a paradigm shift."

Faith, Reason, and Science
COMMENT: I posted this because I basically hold the same views, but Collins states them much better than I could. Science cannot be squared with a literal reading of Genesis, and conflicts with many non-Christian faiths as well. If you set aside aside literalism, though, and allow for the use of allegory and metaphor in religious texts, then it's possible to find, as Collins did, "harmony in the complementary truths of science and faith."

Antisatellite weapons - real, rumored, and false
First, this post needs an extra disclaimer: I have never worked with any intelligence program and have no information other than what's publicly available and my own insights from 15 years of research and writing, as a private citizen, on the capabilities of small spacecraft.
Now, the article. It has two parts. The first concerns questions raised by Democratic Senators about some kind of orbital intelligence-related spacecraft program that reportedly is far over budget. There's no actual information about what the system is, just the inevitable (and if you follow U.S. military space programs, speculation in the press really is inevitable) about whether it's a weapon system, which the U.S. has explicitly said it is not developing.
The second part concerns an alleged satellite called Prowler, launched in 1990, capable of flying from LEO up to GEO and "stealing" signals from other spacecraft close-up. The "expert" who describes this program is unnamed, but there's no reason to think there's truth here. The Air Force has only recently flown its XSS-10 and XSS-11 microspacecraft, which have far less capability than what someone claims we flew 17 years ago. The supposed Prowler also would have needed to fire a large orbit transfer stage, which is a difficult event to hide. You don't just pop up from 300 miles to 22,300.
So all we really know is that some kind of intel program is being attacked for being overbudget. That may be newsworthy in itself, but the rest doesn't merit the hype.

Good news for the American crocodile
COMMENT: An impressive 12-foot specimen was once captured near a construction area I was working on next to the Indian River at Vero Beach, FL. The reptile was kept alive in a covered pool pending a proper return to the wild. The animal got away and was never found again, earning it the name "Houdini." At that point, in 1976, there were as few as 300 of these animals in Florida. There are now an estimated 2,000.
France Opens UFO Files
COMMENT: I've always believed that the small percentage of UFO reports which resist easy explanation might well conceal some important natural electrical, atmospheric, and/or plasma phenomena that were being overlooked due to the ridicule factor. The numbers the French researchers posted, though, are startling: only 9 percent of reports are considered definitely explained, with another 33 percent likely explained. Even the most ardent American UFOlogists assume 90-percent-plus of reports can be traced to to mundane causes. I've not yet read what kind of sorting system the French researchers used, and it may well be the just-quoted numbers apply only to a puzzling minority of reports and not to the entire body of initial data. Still, there will no doubt be a lot in here for students of the bizarre - and just maybe for serious scientific minds as well.

The train wreck has arrived.

Does the Japanese wolf survive?
The subcompact canid is usually listed as extinct as of 1905. However, a photograph has been published showing a specimen killed in 1910. This specimen, though, was later destroyed in a fire, leaving the mounted 1905 specimen (now in the British Museum) as the species' last representative.
COMMENT: As I described in Shadows of Existence (Hancock House, 2006), it's not at all certain the species was extinct before World War One or even World War Two. There's a slim chance it survives even today.

What's New out of Africa
(there is always something new out of Africa)
- Pliny the Elder (23AD - 79AD)
This very old saying is still true in Tanzania's Eastern Arc Mountains, where a patchy collection of forested land equaling roughly a thousand square miles is keeping scientists very busy. In addition to a very distinctive new monkey, the kipunji (Rungwecebus kipunji, described in 2005), new species of frogs and reptiles have been identified, part of a conservation hot spot with one of the world's highest densities of endangered and endemic species. Neil Burgess of the WWF says, “This is a really important place. Biologists who go there just keep finding more and more species.”

Invented before its time
Revisiting the Eastern Cougar
The news that FWS will re-examine the situation gladdens the hearts of researchers whose private networks have shared information on hundreds of Eastern cougar (or puma, panther, etc.) sightings for decades and unsuccessfully attempted to convince state game managers the cat was not extinct. A handful of verified events have led officials in Vermont and Rhode Island to conclude the occasional cougar is living in the wild, but there's continued debate about whether these animals represent escaped or released exotic pets as opposed to a true surviving population.
COMMENT: I've always thought it likely there probably are a couple of pockets, one in Tennessee and one further north, where a few animals just barely hung on out of sight of man. There may have been mixing between wild and domestically-raised cougars, which will ensure things stay confused for a long time. The population of deer, the Eastern cougar's favorite prey, has exploded throughout the East and especially in Pennsylvania, which is likely to lead to increased cougar numbers.

Tomb of Jesus? Perhaps Not.
Not so fast, Jim.
First, the BBC aired a documentary on this 11 years ago, which came under a withering fire of criticism, not just from Christian leaders, but from archaeologists. While no one doubts the genuineness of the find, the names involved were among the most common in Jerusalem 2000 years ago. More tellingly, whatever one thinks of the divinity of Jesus, there's nothing in any history to indicate he was part of the middle-class or upper-class Jerusalem society that could have afforded a family tomb of this sort. That a carpenter's son from the "hick town" of Nazareth would wind up buried in Jerusalem in this fashion along with his parents (remember, his father had died some 20 years before) seems an improbability of the highest degree.
Amos Kloner, the first archaeologist to examine the site, dismissed the idea this was the Biblical Jesus as made-for-television hype. "They just want to get money for it,'' he said.

Clovis People were not the first
COMMENT: I always thought the pre-Clovis "Adam and Eve" scenario was much too simplistic. I have no credentials in this area, but I've always been interested in this fascinating problem and try to keep up on the literature. I've found it hard to believe that all the claims for dates of 20,000 years and older from sites scattered all over the Americas could be wrong. I think archaeologists are slowly migrating to a more complex view, that there were several migrations, by sea as well as land, over thousands of years.

New Species from WAY Down Under
R.I.P. John Heyning
Heyning, deputy director of the research and collections at the Natural History Museum of Los Angeles County, was 50 years old. While he researched everything from dolphins to whale lice, his specialty was ziiphids, or beaked whales, a group of little-known, deep-diving species we are still discovering and classifying. Heyning was instrumental in learning much of what we do know, constantly traveling to beaches wherever a cetacean was washed up. Some years he hauled as many as 30 carcasses to his laboratory. Among other accomplishments, Heyning documented that the common dolphin was actually two species, the short-beaked and the long-beaked.
It is always true that great scientists leave us too soon. Sometimes, though, it really strikes home. Heyning was passionately curious, open-minded, brilliant, and everything else a scientist should be. He spread his knowledge among his colleagues through many papers and monographs and to the public in the book Masters of the Ocean Realm: Whales, Dolphins, and Porpoises (University of Washington Press, 1995).
Goodbye and Godspeed.

NASA and private space firm join forces
"NASA officials signed a memorandum of understanding Tuesday with a U.S. company, Virgin Galactic, LLC, to explore the potential for collaborations on the development of space suits, heat shields for spaceships, hybrid rocket motors and hypersonic vehicles capable of traveling five or more times the speed of sound. Under the terms of the memorandum, NASA Ames Research Center, located in California's Silicon Valley, and Virgin Galactic LLC, a U.S.-based subsidiary of Sir Richard Branson's Virgin Group, will explore possible collaborations in several technical areas employing capabilities and facilities of NASA's Ames Research Center."
COMMENT: This is smart thinking on NASA's part. The agency is not getting, and apparently is not going to get, the funding it needs to develop all the technology needed for future exploration. Collaboration is a must. It's also a welcome change from the days when Dan Goldin was NASA's administrator and dismissed private space efforts as a joke.

THEMIS mission successfully launched
As NASA puts it,
"THEMIS is a mission to investigate what causes auroras in the Earth's atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of color. Discovering what causes auroras to change will provide scientists with important details on how the planet's magnetosphere works and the important Sun-Earth connection."
A really cool video animation is available here:
http://learners.gsfc.nasa.gov/mediaviewer/THEMIS/
The five microsatellites (dry mass 77kg) are incredibly sophisticated, packed with instruments and with booms that telescope out as far as 20 meters. The prime contractor, Swales, explains the spacecraft in detail at this site:

Good and Bad News on Science Literacy
The good news was offset by a rise in the number of people who believe in pseudoscience such as astrology and things that, at the very least, cannot be proved, such as extraterrestrial visitors.
COMMENT: Prof. Miller lumped "belief in Bigfoot" with fortune-telling, etc., and I must object cryptozoology does not belong there. Cryptozoology deals in falsifiable hypotheses (e.g., there either is or is not a large unclassified North American primate) and thus is a legitimate branch of zoology, even if overenthusiastic holders of particular ideas are often unscientific in their approach.

Stone Age Chimps?
The Science of the Lizard
COMMENT: In other dino-science milestones, The Annals of Improbable Research in 1995 published a learned (ahem) scientific paper titled, "The Taxonomy of Barney."
Actually, as a parent, I always wanted to make a film called "Barney vs. Godzilla," in which the Purple Pest tries to drive off Godzilla by singing his incredibly inane "I Love You" song, which spurs Godzilla to melt Barney into the pavement with his atomic breath and then stomp the remains into a layer about half a molecule thick to eliminate all chance of resurrection.
