New Air & Space is really cool

Every issue of Air & Space is good, but the new one is especially cool for aviation buffs. X-planes, the best and worst ideas in aviation, the quest for the 250-knot helicopter - heck, the cover alone is worth the price.

Weird "green bomber" sea worm

A new marine worm discovered off California has been given a really cool scientific name: Swima bombiviridis , the "swimming green bomber." The animal (the first species in a new genus - others have been spotted) can distract predators by casing off small blobs of tissue that glow green - starting to glow only after being separated from the main creature. Ranging from two to nine centimeters long, the worms are found at depths of 1,800 to 3,700 meters.
COMMENT: There are more species, especially invertebrates, in the oceans that we do not know than that we do. The age of deep-sea exploration is still just beginning.

Florida's "Muck Monster"

This video from the lagoon near Lake Worth, FL, shows an unidentified creature being referred to locally as "the Muck Monster." It's a sizable animal that remains almost entirely under the surface. A Florida Fish and Wildlife Conservation Commission marine biologist hesitated to venture a guess.
COMMENT: A commenter on this website suggested a large ray, and that might be right. Anything that gets people looking at the seas and wondering, though, has a good side. And we don't KNOW it's a ray....

Happy anniversary - to a fossil find

It's the 100th anniversary of the discovery of the Burgess Shale - a formation so filled with fossils that its study led to our understanding of the evolutionary flowering known as the "Cambrian Explosion." Our understanding has evolved over the years, and is still evolving. Some earlier conclusions (including some cataloged in Gould's book Wonderful Life) have changed, but not the importance of the find itself.

MicroSpace News: Conference on Small Satellites

Well, another Smallsat has come and gone. I was only able to spend one day this year, but that was enough to get the feeling of camaraderie that always makes it such a pleasant experience. Our keynote speaker from the Army challenged small-satellite enthusiasts to prove their preferred solution for military tactical intelligence and communications needs (small satellites, of course) was sompetitive or superior to the options of UAVs and airships.My presentation on DARPA's fractionated architecture (F6) project went very well. Thanks to Pat, Jaimie, Yvonne, and all the rest of the USU/Space Dynamics Lab crew who did their usual super job in arranging this meeting!

NASA works on space reactor

NASA, in cooperation with the DOE, is moving ahead with technology testing under NASA's Surface Nuclear Power program. This is intended to produce a relatively small, low-maintenance, durable, and safe fission reactor to power a lunar base. NASA Glenn Research Center engineers are using a Stirling engine generating electricity from the heat provided by a liquid metal working fluid, which will be heated by the fission reactor.
COMMENT: Long-term space exploration, especially human exploration, doesn't work without nuclear energy. Some form of fission or (eventually) fusion reactors must provide stable power where solar energy is insufficient (that is, for any sizable base or spacecraft on Mars or beyond) or unreliable (lunar darkness lasts two weeks, and Martian dust storms are nasty). I understand concerns about nuclear power, but this isn't the 1960s. Our ability to build, launch, and operate nuclear systems safely has advanced enormously, and we have to deal with the fact that there just isn't an equivalent source of power for these kinds of missions.

A new theory of everything?

Ever since we humans came up with the idea of quantum mechanics, we've had trouble conceptualizing it in a way that made any sense. An especially difficult aspect of quantum theory is superposition: the idea that a particle can be in more than one state at a time. The Invariant Set Postulate, suggested by Tim Palmer, says the problem isn't that the particle can actually be in two states at once, any more than Schrodinger's cat can be both dead and alive: the problem is that we don't have the right framework to perceive what state it's in. However, everything does fall into reality and nonreality, according to his postulate, with the former (the "Invariant Set," since everything in it has, and always has been, real) a subset of all possible realities.
COMMENT: It's not clear yet whether this is a law or even a testable theory, since Palmer doesn't suggest any experimental way to verify whether there are or are not states of reality outside the invariant one we can perceive. (I think I got that right.) But, according to this article, the idea may still nudge us closer to the Holy Grail of science, a unified theory of physics. To me, it's just fascinating that human brains can come up with this stuff.

Ares and the future of Marshall Space Flight Center

This article is one of many right now reporting that the Augustine Commission recommendations, which are leaking out all over the place, will doom the Ares-I booster intended to loft the new Orion capsule. As readers know, I never liked the damn thing, and its shortcomings have already caused the Orion's capabilities and capacity to be slashed, so I won't be sorry if it dies. (I will be sorry, of course, about the money poured into it already, but I'm not a believer in the "sunk cost" fallacy that says it always makes more sense to finish the program you began.) As the article points out, though, the rationale for the storied Marshall Space Flight Center, which got its start as the Army's home for Wernher von Braun and company, won't go away. There's plenty of work to do in advacing space propulsion.

Discovery and extinction

Writer Geoffrey Lean takes a rather extreme position regarding human-caused extinction - I've never read anything to suggest we'll lose half the species on the planet in the next century - but he has some interesting nuggets about discovery. In particular, he introduces the Smithsonian's Dr Kristofer Helgen, who has published full descriptions of 23 new mammals and has an astonishing 77 more in the pipeline. Helgen says, "Most people don't realise this, but we are smack-dab in the middle of the age of discovery for mammals."

Elephant teaches herself the harmonica

Seriously. What's amazing about this story is that the elephant in question, an English zoo inhabitant named Five, was not taught to play an instrument by humans in order to amuse the visitors. Someone left a harmonica within trunk range, and Five was toying with it and realized it made interesting noises. She kept experimenting on it and now does what the keepers, at least, call playing a tune.
COMMENT: This story, if it's accurate and not overhyped, raises some fascinating questions about what an elephant finds interesting and how "lower" mammals react to musical tones.

Houston, we have a shortfall.

The Augustine Commission created to examine options for human spaceflight is saying what everyone knew but most would not admit. With the current NASA budget, we're not going anywhere. Not the Moon. Not Mars. Nowhere beyond Earth orbit. Panelist Sally Ride, looking at the cost projections, said, "There was not enough money to even start the lunar systems."
A $3B/year plus-up for NASA, which has the same chance of happening under the current Administration and Congress as the stapler on my desk has of becoming a sentient life form, would put us on the Moon in 2025, five years later than the current schedule (which originally said 2018).

"Put out the stars.
Slam shut the teeming skies.
Abandon in place.
Burn out your eyes."

Giant carnivorous plant discovered (seriously!)

From the Philippines comes news of a new species of pitcher plant: Nepenthes attenboroughii (after naturalist David Attenborough). According to its co-discoverer, "The plant is among the largest of all carnivorous plant species and produces spectacular traps as large as other species which catch not only insects, but also rodents as large as rats."
COMMENT: Almost big enough to catch the smallest deer! (previous post). OK, not really, but darn impressive. The inventiveness of nature is endless....

Smallest deer among new species

World Wildlife Fund scientists report that over 350 species have been discovered in the Himalayan region over the past ten years. While they include a gliding frog and two catfish which have evolved "sticky" bellies to cling to the bottoms of streams, the star is the miniature muntjac, a deer weighing just 11 kg and originally mistaken for a juvenile of a known species. Nepal's forest and soil conservation minister said a more thorough, systematic search of the region might find ten times as many species.

TWO DAYS TO THE CONFERENCE ON SMALL SATELLITES

T. rex stuck to small prey?

As I've said, all Tyrannosaur news is automatically considered cool. Even this article, which suggests the biggest theropods were not actually good at bringing down large prey. Two scientists argue that the paucity of fossils of young herbivores, compared to the large number of eggs that we know were laid, indicates predators were mowing down the youngsters. This and other evidence implies that even the biggest predators avoided the stupendous battles with adult Triceratops, Ankylosaurus, etc. in favor of small stuff they could gobble whole.

COMMENT: It all makes sense - to a point. Predators will chomp anything they can find - the more defenseless, the better, although with an appetite like that of an adult T. rex, there is some minimum size beyond which prey wouldn't be worth the effort.
Here are my (admittedly amateur) thoughts, though. My reaction to this theory is the same one I had to the arguments T. rex was primarily a scavenger. Either way, the damn thing is just over-equipped. Nature may make mistakes in the evolutionary process, but she doesn't turn out animals with greater size and more armament than needed - that would be wasteful. A predator six or seven meters tall, with a head the size of a Smartcar and serrated teeth as big as bananas, just doesn't seem logical unless the demands of getting a meal - the results of the constant "arms race" between predator and prey - required it to become that big and that well-equipped. The carnage among younger herbivores might well have been due to the smaller predators, like Velociraptor, as well as juveniles among Tyrannosaurus, Gigantosaurus, etc. What makes the most sense to me is still the idea that T. rex specialized in big prey.

Pterosaurs: good fliers after all?

The debate in paleontology over how good the "flying reptiles" (pterosaurs) were at actual flying has been long-running and sometimes fierce. New analysis of a well-preserved specimen from China indicates that networks of unique fibers in the animals' wings gave them the kind of precise control birds have today.
COMMENT: I doubt this one find will settle things. Even if the early species in this study was a good flier, were later and larger (including some MUCH larger) pterosaurs equally capable, or were some mainly gliders? Either way, pterosaurs will maintain their hold on the human imagination. Flying vertebrates the size of aircraft have a way of doing that.

More evidence "hobbits" were a separate species

A new study, the first to use a comparison technique called cladistic analysis, reports on the results of examining the bones of the Flores "hobbits." The result: Not only were the hobbits a separate species, but they diverged from our own far earlier than thought - perhaps 2 million years ago.
COMMENT: I understand why some anthropologists have been leery of accepting a new species when we have a key bone, the cranium, from only one individual. However, I think the debate is tipping toward the position this amateur has always held: that we have a fascinating new species of human on our hands.

Augustine Commission public meetings

The latest of the Augustine Commission's public meetings is being held in DC today. A lot of material, some of it from alleged insiders and some openly published, as been trickling out of the Commission's work - although what is popping up in the press has sometimes been contradictory. My problem with the several public meetings the Commission has held in various locations (overall, a good thing) is that, if you review the agenda for each meeting, 15 to 30 minutes is allocated for public comment. Fifteen minutes? What kind of meaningful comment are you going to get in a window like that? Remaining meetings of the Commission (scheduled to report out by 8/31) should be extended so there is at least an hour for members of the public (remember who is funding all this) to make comments.

Follow the Whale

How do you track bowhead whales that spend much of their time in remote, unobserved, icy waters? Answer: with a coalition of agencies deploying all the tools of modern technology, including sonar and satellite transmitters fired by air gun into the whale's wall of blubber. This is an interesting look at how scientists find out what an enigmatic animal (bowheads may be the longest-lived vertebrates on Earth) is up to.

2009: A Space Dud

The premiere of the new space adventure show Defying Gravity had a decent premise and some cool space scenery. Also, it had.... um, well, not much. One problem most space shows and films have is that it's too expensive to simulate everything being in zero gravity, and this show is not set far enough in the future to postulate any form of antigrav breakthrough. The idea of the space suit with some kind of magnetic nanofibers is probably as good a workaround as anyone could come up with, but why doesn't the astronauts' hair float? And the rest is soap opera. The good ship Antares and her mission are interesting, but her crew would never have been cleared for a space mission by the flight surgeons and head-shrinkers of any real agency. Junk it up with a birth-controlling government (which is relevant to what?) and a sinister space agency official (a knockoff of the James Cromwell character from Space Cowboys) and you have....some cool space scenery. Somebody deorbit this turkey soon.
