Humans do it quickly

Marshall Islands

A team of scientists from Japan have found evidence that the human settlement of the Marshall Islands in the central Pacific Ocean occurred almost immediately after those islands emerged from beneath the sea. Though it had been previously believed that a thousand years had to pass until these newly emerged islands had developed sufficient vegetation for humans to occupy them, the evidence from this study shows that humans not only showed up almost immediately, they acted to vegetate the island themselves in order to make it habitable.

The scientists drilled four cores just off the western shore of Laura Island, the largest island of Majuro Atoll, as well as thirteen trenches on that same island, in order to determine when the island first emerged from under the sea. They also excavated a well-preserved bank at the center of Laura Island to study the human occupation of the island.

What they found was that the Atoll emerged from underwater approximately 2000 years ago, triggered by a fall in sea level. More surprising, the first evidence of human settlement appeared to occur at almost the same time.

Apollo astronaut has been forced to return camera to NASA

7:43 am

Apollo astronaut Edgar Mitchell has been forced to return to NASA the camera he used on the Moon.

[He had been allowed to keep the camera after his return in accordance with] a practice within the 1970’s astronaut office that allowed the Apollo astronauts to keep equipment that hadn’t been intended to return from the moon so long as the items did not exceed weight limitations and were approved by management.

Chile’s powerful Cerro Hudson volcano is threatening to erupt

1:41 pm

Chile’s powerful Cerro Hudson volcano has come back to life and is threatening a major eruption.

Patagonians are worried. Many remember Mount Hudson’s catastrophic eruptions of 1971 and 1991. The latter eruption was one of the most violent registered eruptions in Chile, and lasted for five months. At its peak it turned day into night, making the banks of nearby Huemules, Cupquelan and Ibáñez Rivers collapse with ash. Many areas in the region are still covered with ash, pumice and other volcanic rocks. “These are the characteristics of this highly explosive volcano,” said Juan Cayupi, a volcanologist at the National Emergency Office.

LHC’s first year’s hunt for the Higgs is ending

8:35 am

The first year’s hunt by the Large Hadron Collider for the Higgs particle is ending.

Vivek Sharma of the University of California, San Diego, who heads the search for the Higgs at [one experiment], points out that results . . . have already ruled out, with a confidence of 2 sigma, a Higgs mass of between about 145 and 400 gigaelectronvolts, and that the LHC’s predecessor, the Large Electron Positron collider, ruled out a Higgs mass below about 114 gigaelectronvolts. So the Higgs, if it exists, almost certainly lies in the gap between the two. According to Sharma, the extra data to be collected in 2012 once proton-proton collisions resume in March will allow the CERN scientists to “either find the Higgs in this mass range, or wipe it out”.

If the Higgs particle turns out not to exist, it will mean that physicists will have to go back to the drawing board to explain all the phenomenon seen in the subatomic world.

NASA Inspector General Paul Martin Is Not Going to Comment About An Abused Elderly Woman in Botched Moon Rock Sting

8:26 am

NASA Inspector General Paul Martin has refused to comment on his office’s abuse of an elderly woman during botched moon rock sting.

Due to the fact that Inspector Generals are independent of the agency they “inspect” (this is actually a very good thing) NASA management has near zero ability to affect the behavior of the IG’s office – or publicly comment on it. Paul Martin is apparently quite comfortable with not explaining to taxpayers (he works for them too) why an elderly woman was roughed up and detained by half a dozen police officers with weapons and then released – with no charges filed after 5 months. That is his call to make. Alas, only a truly insensitive creep would think that it was O.K. not to at least express regret that this situation happened to a small, elderly woman the way that it did. But Martin is tone deaf and oblivious to the real world aspects of what his office does.

Astronomers have proposed that the cloud of dust that surrounds about 50% of the supermassive black holes at the center of galaxies comes from destroyed planets

8:13 am

Science better than fiction: Astronomers have proposed that the cloud of dust surrounding about 50% of the supermassive black holes at the center of galaxies comes from planets that were ripped apart and smashed by that black hole.

Collisions between these rocky objects would occur at colossal speeds as large as 1000 km per second, continuously shattering and fragmenting the objects, until eventually they end up as microscopic dust. Dr. Nayakshin points out that this harsh environment – radiation and frequent collisions – would make the planets orbiting supermassive black holes sterile, even before they are destroyed. “Too bad for life on these planets”, he says, “but on the other hand the dust created in this way blocks much of the harmful radiation from reaching the rest of the host galaxy. This in turn may make it easier for life to prosper elsewhere in the rest of the central region of the galaxy.”

Obama Administration Pushing for Solar Projects on Public Lands

10:57 pm

Coming to a state near you (until the project goes bankrupt and leaves behind a financial and environmental ruin): The Obama administration this week identified seventeen sites in six Western states, all on public land, as prime locations for solar energy projects.

To me, the best indication that something is not quite right with this proposal is that the solar industry itself has doubts.

Environmental groups hailed the announcement, but the solar industry was guarded in its response. Rhone Resch, president and CEO of the Solar Energy Industries Association, said he had “some significant areas of concern” about the solar energy zones@ Flexibility in project siting and access to transmission were crucial to financing and development of utility-scale solar power plants, Resch said, adding that he was optimistic a balanced approach could be found.

You would think the solar industry would be thrilled to get this support from the government. That they have reservations is a serious red flag.

Two hacker attacks of American climate satellites in the past four years

1:12 pm

A congressional report today revealed that two American climate satellites were attacked by hackers in the past four years.

In October 2007 and July 2008, a NASA-managed Landsat-7 satellite experienced 12 or more minutes of interference, and a Terra AM-1 satellite was disrupted for two minutes in June 2008 and again that October for nine minutes, according to Bloomberg Businessweek’s analysis of the annual report by the U.S.-China Economic and Security Review Commission. The report says the hackers gained access to the satellites — both are used for Earth climate and terrain monitoring — through the Svalbard Satellite Station in Spitsbergen, Norway. It’s believed the attackers may have hijacked the Internet connection at the Norway ground station to interfere with the operation of the satellites.

Dismantling the last U.S. hydrogen bomb

9:40 am

Dismantling the last American hydrogen bomb.

The [9 megaton] B53 was designed in the 1950s and replaced 500 B41s, which had a yield of 25 megatons. The largest nuclear device ever built and tested was the 27 ton Russian AN602, which had a yield of 50 megatons. It was eight meters (26 feet) long and 2.1 meters (6.9 feet) in diameter. Only one of these was built. The Russians followed the Americans in phasing out large yield bombs in favor of smaller, and more numerous ones. This was largely the result of ICBM warheads designed to carry multiple nuclear weapons.

According to Zubrin, Obama about to terminate all NASA science

8:32 am

According to Robert Zubrin, the Obama administration is planning to terminate all funding to NASA’s planetary program, while cutting back significantly on its astronomy program.

Word has leaked out that in its new budget, the Obama administration intends to terminate NASA’s planetary exploration program. The Mars Science Lab Curiosity, being readied on the pad, will be launched, as will the nearly completed small MAVEN orbiter scheduled for 2013, but that will be it. No further missions to anywhere are planned. After 2013, America’s amazing career of planetary exploration, which ran from the Mariner probes in the 1960s through the great Pioneer, Viking, Voyager, Pathfinder, Mars Global Surveyor, Mars Odyssey, Spirit, Opportunity, Mars Reconnaissance Orbiter, Galileo and Cassini missions, will simply end.

Furthermore, the plan from the Office of Management and Budget (OMB) also leaves the space astronomy program adrift and headed for destruction. The now-orbiting Kepler Telescope will be turned off in midmission, stopping it before it can complete its goal of finding other Earths. Even worse, the magnificent Webb Telescope, the agency’s flagship, which promises fundamental breakthroughs in our understanding of the laws of the universe, is not sufficiently funded to allow successful completion. This guarantees further costly delays, with the ensuing budgetary overruns leading inevitably to eventual cancellation.

I suspect these cuts have been leaked now, months before the budget is publicly released, in order to whip up support for funding these programs. I also find it distressing that these programs, which cost practically nothing, are targets, while others that cost many many more billions (in NASA and elsewhere) remain fully funded.

Doubts on Display from Congress during hearing on Private Space

8:59 pm

Several Congressmen expressed doubts about and resistance to the new private space manned effort by companies like SpaceX during hearings today in the House.

Let’s be honest: it’s all about pork and only pork. Unfortunately, the new companies don’t deliver the same kind of pork to the right congressional districts, even if they might deliver a real product faster and for less money. To quote the article:

Dana Rohrabacher, R-Calif., rallied to the industry’s defense, citing a “hostility” to the private space industry. “Much to my dismay, I see some of the worst elements of decision making,” he said. “I see an anti-commercial-space attitude that could have very negative consequences.” Rohrabacher (who represents a district near SpaceX’s headquarters) seemed to chide Hall and Johnson, the two Texans who chair the panel, for parochial views. “Focusing on one’s own district and directing federal funds seems to be having a major impact on this decision,” he said.

As we anticipated yesterday, there were other regional pleas connected to the word of choice heard in the halls of Congress: jobs. Rep. Hansen Clarke, D-Mich., for instance, asked how the space contract could be used to create jobs in his district of metropolitan Detroit. The witnesses made the most diplomatic kowtows they could. “I’ve been pushing SpaceX to use more automotive suppliers,” Musk responded. Other space industry execs went on to claim Michigan subcontractors, to praise the auto industry, and to speak of spin-offs from space science programs.

Catching an avalanche on Mars, as it happens

4:38 pm

The Mars Reconnaissance Orbiter team today released this really cool image from Mars, showing an avalanche near the North Pole, in progress. The image looks directly down the cliff face from above. At the base of the cliff we can see the dust cloud from the crash of material billowing out away from the scarp.

What impresses me most about this image is that it was taken by an orbiting spacecraft approximately 200 miles above the planet’s surface, moving at thousands of miles an hour. Yet, the camera not only had the resolution to see the cloud of dust, it could snap the image fast enough to capture the actual fall of material (the white wisps down the side of the cliff that are reminiscent of a waterfall).

Also intriguing is the visible steep face of the cliff face itself. I know a lot of rock climbers who would love to literally get their hands (and chocks) on that rock face. And in Mars’s one-third gravity, rock climbing would surely be different.

The cause of white nose, the killer of bats

11:14 am

Scientists today confirmed that the fungus, Geomyces destructans, causes white nose syndrome, the deadly killer that has been wiping out cave-hibernating bats throughout the eastern United States.

A science team led by David Blehert of the National Wildlife Health Center in Madison, Wisconsin captured healthy little brown bats and infected them with the fungus while they were in hibernation, some by direct application and others by putting them in contact with already infected bats. After 102 days, all of the first group had developed white nose on their muzzles and wings, while 16 of 18 of the second group had become infected as well.
