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.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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.

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.

Shake-ups in the Google Lunar X-Prize competition

10:02 am

One team has withdrawn and two big-name executives have left another team in a shake-up at the Google Lunar X-Prize competition.

This key quote however tells us the real state of the competition, which sadly does not look good:

The competition has repeatedly moved back the deadline to win the prize, which is now set for Dec. 31, 2017. At least one of the 16 remaining teams much announced a launch contract by the end of this year for the competition to continue. The rest of the teams would then have until the end of 2016 to announce launch contracts to stay in the race.

The team that withdrew says it plan to continue its effort but outside the competition. Either way, it looks like someone has to commit to a launch sometime in the next few months or the competition either has to push back its deadlines again or declare no winners. This will be a sad conclusion, as it is entirely possible for private financing to get this done. A failure however would make that appear impossible.

Technical problems for cosmic ray detector on ISS

9:53 am

The failure of a second of four cooling pumps on the Alpha Magnetic Spectrometer on ISS threatens the science instrument’s ability to continue its observations.

The AMS continues to gather science data using the three remaining pumps. They are part of a liquid carbon dioxide cooling system that is meant to dissipate heat as the AMS, which is on the outside of the space station, cycles in and out of sunlight during each 90-minute orbit of Earth Only one pump is needed at any given time. One failed in February 2014 and at least one of the other three is showing possible signs of trouble.

Since the 8.5-tonne AMS began operating in 2011, it has tracked more than 69 billion cosmic rays flying through its detectors. Its goal is to search for antimatter and dark matter. In 2013, AMS scientists reported measuring numbers and energies of positrons that hinted at, but did not confirm, the existence of dark matter.

The news article suggests that the instrument is now working with only one reliable pump. It also is possible that repairs might be done by astronauts on ISS during a spacewalk.

Some background: AMS cost $2 billion and about 20 years to build. It only got launched because Congress ordered NASA to launch one more shuttle mission to ISS to get it there.

Atlas 5 successfully launches U.S. military satellite

9:45 am

The competition heats up: ULA’s Atlas 5 rocket today successfully launched a U.S. Navy military communications satellite into orbit.

ULA’s big selling point for its very high prices is its very high reliability. This was its 99th consecutive launch success for the company, going back to 2006. It was also the 127th in a row for the Atlas 5.

The problem is that a majority of these launches were government payloads, which up until now has been willing to pay top dollar. For ULA to really compete successfully, it needs private customers, and they appear unwilling to pay that top dollar, going instead to SpaceX. It is for this reason the company is pushing hard to develop a more efficient and less costly rocket.

Manned Soyuz heads for ISS with new crew

9:38 am

A new crew was successfully launched into orbit last night by a Russian Soyuz rocket.

This is the mission that Sarah Brightman was originally going to fly on as a tourist — before she backed out or was rejected by the Russians as a unqualified. Instead, it carries one Russian who is going to take over as commander of the station for a long term mission, and two short term astronauts, from Kazakhstan and Denmark, who will remain in orbit for only about 10 days.

They are taking the long, two-day rendezvous route to ISS, so they won’t actually dock until Friday.

Blue Origin wins financial incentives to build in Florida

9:31 am

The competition heats up: Local county officials in Florida have awarded Blue Origins $8 million in grants to encourage it to set up launch operations in Florida.

The money comes from property tax revenue from new commercial and industrial construction in North Brevard, under a process the Brevard County Commission created in 2011 to help spur economic development in North Brevard. Blue Origin plans to build rockets on the Space Coast, and launch them from Cape Canaveral Air Force Station. The company, founded by Jeff Bezos, the billionaire chief executive officer of Amazon.com, would create 330 jobs with an average wage of $89,000, and plans to make a capital investment of $205 million to $220 million.

The company is being referred to as “Project Panther” in county documents, because Blue Origin has not officially disclosed its plans. Bezos is scheduled to be in Brevard County on Sept. 15 for a major announcement on the commercial space industry.

This news helps indicate what Bezos’s September 15 announcement will be about. They are likely to announce that the company is completed its arrangements for building its spaceport in Florida, and is now going to proceed. Up until now the company, which keeps its plans very close to its vest, has been vague about its future launch plans, especially after it lost its competition with SpaceX for leasing a launchpad at the Kennedy Space Center.

Blue Origin abandons patent for barge-landing a rocket

9:24 am

The heat of competition: After losing a decision of the U.S. Patent office in a dispute with SpaceX, Blue Origin has withdrawn the patent it was awarded in March 2014 for vertical landing a rocket on an ocean-going barge.

In an order made public today, the U.S. Patent Trial and Appeal Board granted a motion to cancel the remaining 13 of 15 claims in the Blue Origin rocket-landing patent. Blue Origin itself had made the motion to cancel those claims, effectively acknowledging that its case was lost.

Blue Origin, based in Kent, Wash., has separately filed a “reissue” patent application covering the same general area. However, SpaceX has already attempted multiple rocket landings at sea and would likely be grandfathered in, allowing it to continue the practice, even if Blue Origin were to ultimately succeed in securing a valid patent.

The two companies are definitely in a heated competition. This is not the only legal dispute they have had, with SpaceX winning previously as well. Blue Origin had challenged the award of a 20-year lease to SpaceX of its launchpad at Kennedy. It lost.

In this case, it was absurd on its face for the patent office to award this patent to Blue Origin, especially since, at the time it did so, SpaceX was clearly already doing this exact thing.

Curiosity spots a spoon on Mars!

9:04 am

The spoon on Mars

Very cool image time! In one of Curiosity’s recent images of the Martian surface on the slopes of Mount Sharp appears what looks like a long thin spoon jutting horizontally out of the ground.

The shadow below the feature is strong evidence that that this almost certainly a real object, shaped exactly as we see it. However, it is not an artificially created spoon. If you look at both the full raw image as well as zoom in on the feature itself, you will see that it is something that formed naturally due to Mars’ low gravity and the geology here. The spoon is a thin prong of harder material that has remained intact as the ground below it has been slowly eroded away by the ever-present but very weak Martian wind. If you look close you can see that harder material extend back into the rock behind the spoon.

Some of that erosion might also have been caused by flowing water sometime in the past, but to confirm this will take additional geological research.
