Police arrest 8 protesters camping illegally on Mauna Kea

8:54 am

Last night police arrested 8 protesters who were camping illegally on Mauna Kea in opposition to the construction of the Thirty Meter Telescope.

I have posted below the fold a video of the arrests. To me, the significant take-away from this video is the scale and permanence of the tent structures that these people have built opposite the Mauna Kea visitors center. The emergency order forbidding camping had gone into effect on July 14. Yet, the impressive buildings they have made of wood and poles have clearly been allowed to stand. This suggests that the state is really not serious about enforcing the law and stopping the protesters from camping on the mountain.

Aerojet Rocketdyne makes $2 billion offer to buy ULA

11:11 pm

The competition heats up: Rocket engine-maker Aerojet Rocketdyne has reportedly made a $2 billion offer to buy the rocket company United Launch Alliance (ULA), a partnership of Boeing and Lockheed.

If this deal goes through, it will put the squeeze on Jeff Bezos’s Blue Origin, which presently has a contract to build rocket engines for ULA. Aerojet Rocketdyne had wanted that contract and had lost out. If they buy ULA, they could then kick Blue Origin out and take on the contract themselves.

I am honestly not sure what to make of this whole thing, however. It could be that Aerojet, having lost a number of contracts and faced with a significant lose in business, has decided it needs to become a rocket company to survive. It could also be that the corporate heads of ULA have decided that the company’s effort to replace its Delta and Atlas rockets with Vulcan is too risky, and they are better off taking the cash and running.

Or it could be any number of other reasons. We shall have to wait and see how this plays out.

Republican revolt over Iran deal vote

9:46 am

The House Republican leadership is facing a revolt from its membership of their plan to vote on the Iran deal.

Speaker John Boehner and other GOP leaders got an earful Wednesday morning from lawmakers who say President Barack Obama has not disclosed so-called “side deals” between the International Atomic Energy Agency and Iran, and therefore is crosswise with the law that gives Congress review power over the accord.

GOP leaders are likely to change their approach Wednesday, and are now considering a vote on Rep. Peter Roskam’s (R-Ill.) resolution that would delay a disapproval vote because they believe Obama has not disclosed some elements of the deal.

The article correctly notes that, because of the Corker-Cardin bill pushed through several months ago by this same Republican leadership, it is almost impossible to block the Iran deal and that this revolt will likely change nothing. However, it also notes that Roskam was once part of that same Republican leadership and was pushed out last year. His actions here suggest to me that he might be maneuvering to position himself as a likely Boehner replacement.

More details here. The story above is from a Democratic-leaning news source. This second link is from a conservative site. This story also notes that the Republican leadership is actually so stupid they are planning the vote on the Iran deal on take place on September 11. I wonder what happened that day 14 years ago?

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Closing in on Ceres’s bright spots

9:33 am

Ceres's bright spots

Cool image time! The Dawn science team has released a new close-up of Ceres’s Double Bright Spot.

The new up-close view of Occator crater from Dawn’s current vantage point reveals better-defined shapes of the brightest, central spot and features on the crater floor. Because these spots are so much brighter than the rest of Ceres’ surface, the Dawn team combined two different images into a single composite view — one properly exposed for the bright spots, and one for the surrounding surface.

They have also released a detailed topographic map of the crater as well as a fly-around video, which I have posted below the fold. The interesting take-away from this new data is that, while the bright spots look at first glance remarkably like the snow-cap on a mountain-top, they are actually at the low spots in the crater. This suggests that they are instead material that has either bubbled up from below, or flowed downward to the crater bottom.

Be sure you click on the link and look at the full resolution image.

Spaceport head says Lynx to launch in early 2016

9:18 am

The competition heats up: The president of the spaceport in Midland, Texas, said today that XCOR’s Lynx suborbital spacecraft will complete its first test launch in the second quarter of 2016.

My readers know that I have been very skeptical of XCOR. They also know, if they have read closely, that I would be thrilled if they proved me wrong and succeeded. I think we shall find out one way or the other next year.

Venus probe about to rise from the dead

9:07 am

Five years after it failed to enter Venus orbit as planned, the Japanese probe Akatsuki is about to try again, in December.

The article provides an interesting and detailed explanation of what had gone wrong in 2010, and then describes the amazing things engineers have done to make this second attempt even possible. If they succeed it will be one of the most brilliant achievements in the history of space exploration.

Boeing names its CST-100 manned capsule Starliner

2:05 pm

The competition heats up: Boeing today unveiled “Starliner” as the new name for its CST-100 manned capsule.

This intensifies the competition because the new name is something the public can grab and identify. As long as Boeing was using the boring acronym they were holding back to stay in the boring do-nothing pork-laden government-funded NASA environment. Grabbing the public means they want the public to buy this product.

School lunch program collapsing under Obama

7:32 am

Doing the job the Republicans in Congress are too cowardly to do: The more costly and less appealing foods imposed by the Obama administration on the school lunch program in order to promote better eating have been rejected by so many students that the entire program faces bankruptcy

President and first lady Michelle Obama’s bid to cut kid obesity through new demands for more costly but healthier food is financially crushing the nation’s school cafeterias, forcing staff cuts, boosting waste and killing plans to buy new equipment, according to an industry association.

A new survey from the School Nutrition Association reported that 70 percent of the nation’s lunch programs have been financially “harmed” by the new low-salt, low-sugar menus and that a stunning 93 percent report fewer students buying the chow. “Meeting these mandates has harmed the financial health of nearly 70 percent of school meal programs surveyed, with fewer than 3 percent reporting a financial benefit,” said the survey. Some 49 percent of the responding schools said they were forced to cut cafeteria staff as a result.

Not surprisingly, the school cafeteria industry is calling for greater funding to solve the problem. I’d rather see the entire program revamped and trimmed significantly. There is no reason for the government to provide lunches for most of the nation’s children. The program was originally created to feed only the poorest. As with most government programs, it has since grown way beyond that original goal, to a point that is absurd and wasteful.

VA fiddled while sick veterans died

10:56 am

Obamacare will soon make this kind of medical care standard for everyone! A new audit of the Veterans Administration estimates that 307K patients died while waiting for requested treatment.

Read the entire article. The malfeasance and corruption at the VA is far worse than this, and goes back decades to the agency’s very beginnings. Also, giving the VA more money won’t fix it.

[T]he VA has seen its budget grow from $87.6B in 2009 to $152.7B in 2014. The 2016 budget request is $165.5B. This includes $70.2B in discretionary spending, with $63B going to medical care. So the department is asking for plenty of money to “help” veterans, but isn’t spending the money wisely.

Most of the issues mentioned in this audit were first identified in report issued in 2010. So why didn’t the VA act then to attack these problems?

Things move slowly in government, but if the work process system was this bad, why wasn’t it fixed? A part of it might be the VA wasn’t interested in fixing the system because it didn’t want to lose any money. This is a horrible theory, but it isn’t like the VA hasn’t had issues for years.

The time has come to shut these failed government agencies down.

New engineering gives a man paralyzed from the waist down the ability to walk again.

9:45 am

Using a new exoskeleton design combined with non-invasive spinal simulation engineers have made it possible for a man paralyzed from the waist down to walk again.

Leveraging on research where the UCLA team recently used the same non-invasive technique to enable five completely paralyzed men to move their legs, the new work has allowed the latest subject, Mark Pollock, to regain some voluntary movement – even up to two weeks after training with the external electrical stimulation had ended.

Pollock, who had been totally paralyzed from the waist down for four years prior to this study, was given five days of training in the robot exoskeleton, and a further two weeks muscle training with the external stimulation unit. The stimulated and voluntary leg movements have not only shown that regaining mobility through this technique is possible, but that the training itself provides a range of health benefits in itself, especially in enhanced cardiovascular function and improved muscle tone.

The new system has been created as an amalgam of a battery-driven bionic exoskeleton that allows users’ leg movements to propel the unit in a step-by-step way, and a non-invasive external stimulator to trigger nerve signals to create the leg movements. In this way, Pollock made significant progress after being given just a few weeks physical training without spinal stimulation and then five days of spinal stimulation exercise an hour a day over a week-long period. “In the last few weeks of the trial, my heart rate hit 138 beats per minute,” said Pollock. “This is an aerobic training zone, a rate I haven’t even come close to since being paralyzed while walking in the robot alone, without these interventions. That was a very exciting, emotional moment for me, having spent my whole adult life before breaking my back as an athlete.”

His ability to walk is not achieved easily, and without extensive help and preparation fades. However, the results here are very hopeful that future developments will make it possible for paraplegics to once again walk.

The Earth has a lot of trees!

9:32 am

The uncertainty of science: A new estimate of the number of trees on Earth has increased that estimate seven-fold, from about 400 billion to 3 trillion.

The previously accepted estimate of the world’s tree population, about 400 billion, was based mostly on satellite imagery. Although remote imaging reveals a lot about where forests are, it does not provide the same level of resolution that a person counting trunks would achieve.

Crowther and his colleagues merged these approaches by first gathering data for every continent except Antarctica from various existing ground-based counts covering about 430,000 hectares. These counts allowed them to improve tree-density estimates from satellite imagery. Then the researchers applied those density estimates to areas that lack good ground inventories. For example, survey data from forests in Canada and northern Europe were used to revise estimates from satellite imagery for similar forests in remote parts of Russia.

That these same scientists can, in this same story, also claim with almost certainty that the number of trees on Earth has declined precisely 46% since homo sapiens appeared 12,000 years ago illustrates the difficulty humans have to remain skeptical. How do they get this precise number for the tree count 12,000 years ago? It appears to me that they have allowed the modern environmental agenda of blaming the evil destruction of the environment on humanity to cloud their thinking.

If scientists have discovered a seven-fold error in their count today, I am sure the margin of error for an estimate for 12,000 years ago will be much higher.

High res radar instrument fails on Earth observation satellite

9:18 am

Only seven months after launch one of the two instruments on NASA’s Soil Moisture Active Passive (SMAP) Earth observation satellite has failed.

Launched on Jan. 31, the Soil Moisture Active Passive spacecraft’s objective is to map global soil moisture and to detect whether soils are frozen or thawed. It is the first mission where scientists have attempted to collect high-resolution, high-accuracy soil moisture data, said Kent Kellogg, SMAP’s JPL-based project manager.

NASA budgeted $916 million for the mission and has been working on it for the past eight years. “We do a lot of testing on the ground to make sure the designs will be built properly and will last in the environment,” Kellogg said. “But space is a very unforgiving place, and we can have these kinds of problems where despite our best efforts with design and vigorous testing, something surprises us. It’s very uncommon, but these things can happen occasionally.”

SMAP’s two scientific tools are an active radar and a passive radiometer. They complement each other, making up for the other’s measurement limitations. The broken radar collected soil moisture and freeze-thaw measurements at a higher resolution of up to 1.9 miles. The still functioning radiometer generates more accurate measurements but its resolution is lower at about 25 miles. [emphasis mine]

I am not satisfied by the explanation for the failure expressed above. NASA spent a lot of money for this science satellite over almost a decade. In addition, we have been launching instruments like this for almost half a century, and have by now learned quite well the engineering necessary to keep them operating under the conditions in low Earth orbit. I suspect a screw-up somewhere, which we might or might not ever identify.

Apollo lunar samples crumbling to dust

9:08 am

The uncertainty of science: A comparison between the average particle size of 20 Apollo moon soil samples has discovered that their size has decreased by more than half in the past 40 years.

The differences between the two datasets are stark. For example, the median particle diameter has decreased from 78 microns (0.0031 inches) to 33 microns (0.0013 inches). And in the original sieve data, 44 percent of soil particles were between 90 and 1,000 microns (0.0035 to 0.039 inches) wide; today, just 17 percent of the particles are that large.

The most likely explanation for the degradation is damage caused by water vapor, the scientists say. “Leaching by water vapor causes the specific surface area of a lunar soil sample to multiply, and a system of pores develops,” they wrote in the study, which was published online last week in the journal Nature Geoscience. “These structural changes may be attributed to the opening of existing, but previously unavailable, pore structure or the creation of new surfaces through fracturing of cement or dissolution of amorphous particles.”

I was surprised that in the article above the scientists made no mention of gravity as a factor. These particles were originally formed under lunar gravity, 1/6 that of Earth. I would have thought that their structural strength was partly determined by this, and once brought to Earth’s heavier gravity would have thus slowly deteriorated over time.

Either way, the study illustrates why saving these samples for future researchers was a foolish mistake. Time changes all things, and that change has made these samples no longer a good representation of the Moon. The NASA scientists and managers who decided to store these samples instead of distributing them all for immediate study forgot this basic fact.

The scientists who did this study appear to have not learned this lesson as well. They suggest future samples be stored off-Earth, in a place like ISS. I say, we should instead go to the Moon so often we don’t need to store any samples. When we want a sample, we go and get one.

Soyuz capsule maneuvers to avoid space junk

8:53 am

The manned Soyuz capsule bringing three astronauts to ISS was forced to make a maneuver this morning to avoid a collision with a fragment from a Japanese rocket launched in 1989.

While space junk is an increasing problem, for a object to threaten a manned capsule making maneuvers in low Earth orbit is extremely rare. It appears from the story however that U.S. and Russian trackers thought there was a very good chance of an actual collision and took action to avoid it.

First Falcon Heavy launch now scheduled for April/May 2016

11:22 pm

The competition heats up: SpaceX is now aiming for a spring launch of the first Falcon Heavy.

That first launch will be a demonstration mission without a paying customer. That launch will be followed in September by the Space Test Program 2 mission for the Air Force, carrying 37 satellites. Rosen said the company was also planning Falcon Heavy launches of satellites for Inmarsat and ViaSat before the end of 2016, but did not give estimated dates for those missions.

Though no one should bet a lot of money on this launch schedule, if they get even half this accomplished they will be doing quite well. This, combined with the possibility that they will safely land the first stage of the Falcon 9 by then as well, will put SpaceX in an undeniably dominate position in the launch market.

Iran deal gets enough Democratic votes to pass

10:22 am

Democrats now have enough votes to sustain a veto and thus allow President Obama’s Iran deal to go into effect.

Ed Morrissey says it best:

What’d the GOP get out of all this? What did their huge advantage in the House and their eight-seat majority in the Senate ultimately amount to in terms of concessions? It’s one thing to lose a momentous fight on foreign policy, ceding all of your constitutional leverage in the process, but if you can get some goodies for your side at least you can say it’s not a total loss. Unless I missed something, we got … nothing. Not a thing — not even, in all likelihood, the right to crow and say that our resolution of disapproval passed the Senate with plenty of Democratic support. This fiasco will end with an essentially party-line vote on cloture, leaving Obama free to argue to the world that the deal has the acquiescence of the U.S. Congress. The only thing we get from this is the right to point out later, when this agreement eventually ends with Iran going nuclear and the Middle East being further destabilized, that this disaster is owned lock, stock, and barrel by the Democratic Party. That’s a nice consolation prize, but we’ve known since the beginning that we’d be getting that. What we’ve added to our “winnings” since this congressional kabuki began is precisely nothing.

The reason the Republicans failed here is that the leadership, led by Bob Corker (R-Tennessee), wrote and passed a bill that allowed this treaty to pass without even a majority of Congress. In other words, before they even saw the treaty they agreed to it. And once they saw the treaty they made loud noises, including Corker, about how bad it was, but they themselves had already made it impossible for them to block it.

It is time for these Republican leaders to be fired. It isn’t just Democrats who have betrayed the American people and our friends in the Middle East with this deal, it is this Republican leadership that has decided to help Obama and the Democrats get everything they want. And in turn, this has given the Iranians — still eager to instigate terrorism attacks and war against the U.S. and Israel — everything they want as well.

170 million guns purchased, crime drops by half

10:10 am

More guns, less crime: According to federal government data Americans have purchased more than 170 million guns since 1991, and in that time violent crime has dropped 51 percent.

This evidence strongly suggests that the presence of guns in the hands of honest Americans helps to reduce violence. And while there are many factors contributing to the fall in crime, many which have nothing to do with the purchase of guns by Americans, the statistics here should not be ignored. Gun control advocates always argue that if gun limits are reduced, a blood-bath will follow. This claim has always been proven false, and these statistics do so again.
