Sunspot activity crashes

10:19 am

The monthly NOAA update of the solar cycle was released yesterday, showing the Sun’s sunspot activity in April. It is annotated and posted below.

April 2016 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

After four months of steady decline matched exactly with the low prediction from 2007 (the lower green line curve), in April sunspot activity plummeted to the lowest level seen since January 2011.

This decline shouldn’t surprise anyone. The now ending solar maximum has been the weakest in a century and, as noted here, it is now more than a year since the last X-class solar flare, the most powerful kind, with this solar maximum seeing only 45 X-class events, compared to 126 during the previous solar maximum.

As I have noted repeatedly, the big question now is what will happen during the next solar cycle. Will we get another weak solar cycle or will the sun’s sunspot activity recover? Or will sunspots vanish and will the sun enter a grand minimum, with no sunspots for decades? At the moment no one knows, though some solar scientists favor the latter.

Saturn’s moon Epimetheus

9:14 am

Epimetheus

Cool image time! The picture on the right was taken by Cassini on December 6, 2015, and shows the asteroid-like misshapen moon, too small (only 70 miles across) for gravity to force it into a sphere. Behind it, filling the frame, is gigantic Saturn.

If you look close, you can see one crater that appears elongated, as if the impact was only a glancing blow.

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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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

Long March 7 heads to spaceport

9:01 am

The competition heats up: The first of China’s new generation of rockets, Long March 7, is now on its way to its spaceport for its first launch next month.

The first flight of the 53-metre-tall Long March 7 will take place in late June, according to CASC’s Yang Baohua, and will test the design and performance indicators. The 600 tonne, 3.35m diameter rocket will carry a scaled-down version of a new Chinese re-entry capsule for human spaceflight, chief designer of China’s human space program Zhou Jianping revealed in March.

The article provides some good detailed information about China’s new rockets, noting that this rocket has been designed to launch manned and cargo spacecraft into orbit, making it the equivalent of Russia’s Soyuz rocket. The more powerful Long March 5, set for launch later this year when it will put China’s next space station prototype into orbit, will be their equivalent of Russia’s Proton. In both cases, however, they will be better than Russia’s rockets, more advanced and upgraded with greater capabilities.

The article also makes note of China’s new Wenchang spaceport on the coast, which took six years to build.

Mercury’s transit today

8:50 am

Here are a few links on today’s transit of the Sun by Mercury, which is going on right now.

I could give more, but this event is hardly as important as many new media are saying. It is interesting, and rare, and important in that it helps scientists get a better understanding of the uncertainties in their exoplanet research, but hardly important scientifically.

Consider this however: Mercury’s real orbit has it circle the sun every 88 days. If we could only detect it by the transits seen from Earth, we would only see it cross the Sun in 2006, 2016, 2019, and 2032. Figuring out its real orbit from that data would likely be impossible. Now, I realize that these seemingly random transits are partly determined by the Earth’s own orbit around the Sun, but they still illustrate that our use of transits to detect and characterize exoplanets has its limits. And in science one must always be aware of one’s limits.

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.

Trump calls for a minimum wage increase

9:51 pm

Researching the November Democratic primary: Republican Party presidential candidate Donald Trump on Sunday called for an increase in the minimum wage.

He did add that this is something the states should decide. However, with him pushing it he is helping to make it a political issue that will force an increase, something that has routinely damaged economies and hurt the poorest and lowest income members of society. He also added that he will negotiate with Democrats on his tax plan (which he now called “only a concept”) which will likely cause increased taxes on the wealthy.

As I’ve said, we now have a choice between a liberal Democrat and an avowed socialist/communist. Ain’t that just wonderful?

Death threats to vegan restaurant owners for eating meat again

9:41 pm

Fascists: The owners of a chain of vegan restaurants in California are now faced with boycotts and death threats because, after 40 years of being vegetarians, they have started eating meat again.

Protesters outside of the Cafe Gratitude restaurant in Venice, Calif., over the weekend carried signs that read “It’s not food/It’s violence” and “No animal is grateful to die.” One poster depicted a cow hanging from a rope with the speech bubble “No gracias, madre!” A stick figure of Matthew held up a knife over a pool of blood and said, “I love you…”

The Engelharts told the Hollywood Reporter that they have been receiving death threats. “People have taken up the mob mentality,” Matthew said. “It saddens me that the choices we made in the privacy of our home would lead people to feel so betrayed that it’s elevated to threats on our lives.”

How dare they leave the reservation of liberal/leftwing beliefs and do something different? How dare they? Time to set up concentration camps for traitors like these!

May 6, 2016 Zimmerman/Pratt podcast

9:13 pm

On Friday afternoon I spent 90 minutes with Robert Pratt on his radio show, Pratt on Texas. Unlike most radio hosts, Robert wanted to hear my thoughts not just on the state of the aerospace industry, but also on today’s politics. The conversation thus ranged beyond space during the last half hour. If anyone wants to hear this conversation, the podcast be found here.

Why I use Linux

2:27 pm

Linux can be a pain sometimes, and it requires a bit more hands-on work by the user to make it function, but overall in the ten years since I abandoned Windows and switched to Linux (first with the Debian operating system and now with Kubuntu) I have found my work on my computer to be far more satisfying and successful. I can mostly get things done the way I like to do them, not as dictated by some software geek working at Microsoft’s headquarters.

Which is why this story interested me: “I thought my daughter clicked on ransomware – it was the damn Windows 10 installer.” It describes a number of stories where Windows 10 took control of a person’s computer and imposed an upgrade, against their will.

This story, among many others, only confirmed for me that my decision in 2006 was a wise one. I will never return to Windows, and if I was certain that computer projectors could read Linux laptops I’d switch the laptop to Linux as well.

It is just a shame however that so many people still stick with Windows, as it often makes doing their work difficult, if not impossible. When a product doesn’t work for you, you find another product. That’s how freedom and competition work.

Increased earthquake activity at Mount St. Helens

12:37 pm

Though the increase is not large enough to indicate the likelihood of another eruption, scientists have noted that for the past eight weeks the earthquake rates under Mount St. Helens has been increasing.

Over the last 8 weeks, there have been over 130 earthquakes formally located by the Pacific Northwest Seismic Network and many more earthquakes too small to be located. The earthquakes have low magnitudes of 0.5 or less; the largest a magnitude 1.3. Earthquake rates have been steadily increasing since March, reaching nearly 40 located earthquakes per week. These earthquakes are too small to be felt at the surface.

Once again, these quakes do yet not signal another eruption. They are more likely signs of the mountain’s continuing but long and slow adjustment back to silence after the 1980 eruption. Nonetheless, they bear watching, as a volcano will do what a volcano wants to do.

A review of Al Gore’s movie “An Inconvenient Truth”, ten years later

12:29 pm

climate data showing pause in warming since 1998

The uncertainty of science: A new review of Al Gore’s movie “An Inconvenient Truth”, ten years later after its release, looks closely at the predictions the film made to see if they have come true, or were at least pointed in an accurate direction.

Guess what? The film’s predictions have turned out to be generally wrong. From predicting an ice-free Arctic to a snow-free Mt. Kilimanjaro to more extreme weather to a continuing warming as carbon dioxide increased, Gore’s predictions have each failed.

I especially like the last one, that as carbon dioxide rose the temperatures would rise in lockstep, as predicted by all climate models. The article notes that temperatures have not done so, that the global climate temperature has been practically unchanged since 1998, and backs up this point with a paper published by the science journal Nature.

The graph above is from that paper. The black line that rises above the red, blue, and gold lines is one of the more respected climate models. The other lines are from the actual data. As you can see, the climate model fails to predict the climate, meaning that the theory used to create it is incomplete or inaccurate.

This is not to say that the theory might not be true. Global warming, initiated by the increase in carbon dioxide in the atmosphere, might very well happen. The data shows however that the climate scientists touting this theory do not yet understand the Earth’s complex global climate well enough to prove their theory true. There are other factors influencing the climate they have not yet recognized, factors such as the Sun’s variability and the fact that CO2 by itself is a actually a trace gas and not the atmosphere’s chief global warming component, which is water.

SpaceX’s second first stage barge landing

9:10 am

Below is video of the Falcon 9 first stage landing last night. There isn’t really much to see, because this happened at night. However, I must repeat that this happened at night. In other words, SpaceX was able to bring its first stage down accurately in the middle of the ocean onto a tiny barge in the dark.

Who says the impossible is not possible?

During the live telecast, the audience broke out into a chant of “USA! USA!”, as they did after the previous first stage landings. Can you guess why?

Does Trump have the best space policy?

8:59 am

This opinion column looks at the three remaining politicians campaigning for president, and finds that Donald Trump probably has the most favorable position toward commercial space.

While all three candidates mouth favorable platitudes towards NASA and space exploration, all three also express reluctance to fund a giant government space program. Trump however was the only one to note the positive aspects of commercial space and express

…support for the government partnering with private space companies like Elon Musk’s SpaceX. “I think there needs to be a growing partnership between the government and the private sector as we continue to explore space,” Trump told AIAA. “There seems to be tremendous overlap of interests so it seems logical to go forward together.”

Obviously, one can’t and shouldn’t put much faith in what any politician says during the campaign. Nonetheless, this might be a hopeful sign that if elected, Trump would push to dump NASA’s SLS/Orion and have NASA instead focus on buying space exploration services designed and operated by private companies.

Pima county files motion to dismiss World View lawsuit

8:49 am

In the heat of competition: The Arizona county government that made a deal with the space tourism balloon company World View to help them build their launch facilities in Tucson has filed a motion to dismiss the lawsuit by the Goldwater Institute that claims the deal is illegal.

I don’t know if the deal was illegal, but I suspect that even if it was the county will win and the deal will go through. Too much money at stake.

Global elevation map of Mercury

8:39 am

The science team for Messenger have now released a new digital elevation model of Mercury’s global surface.

The new product reveals a variety of interesting topographic features, as shown in the animation above, including the highest and lowest points on the planet. The highest elevation on Mercury is at 4.48 kilometers [2.78 miles] above Mercury’s average elevation, located just south of the equator in some of Mercury’s oldest terrain. The lowest elevation, at 5.38 kilometers [3.34 miles] below Mercury’s average, is found on the floor of Rachmaninoff basin, a basin suspected to host some of the most recent volcanic deposits on the planet.

If you watch the animation at the link, you will notice that the high points tend to cluster in the lower latitudes, while the low points tend to favor the high latitudes, suggesting a very slightly bulged shape, which is not surprising considering Mercury’s close proximity to the Sun.

The data release today also included an additional map showing the known geological features in more detail.

SpaceX lands the first stage again!

12:08 am

The competition heats up: In tonight’s launch, SpaceX not only put a commercial satellite into geosynchronous orbit, it successfully landed the first stage on a barge, a landing they did not expect to succeed.

Go here to watch a launch replay. The landing is at about 38 minutes.

With this success, I think they have demonstrated that they can recover that first stage in almost every circumstance. The next big challenge: Launch Falcon Heavy and recovering all three of its first stages.

Future Republican battle leans right and anti-establishment

1:10 pm

Three more stories today, in addition to this already posted story (Cruz’s political stature enhanced by campaign) suggest that the Republican Party is going to move rightward and anti-establishment.

The headline of the last story is misleading. What it is really about is how Cruz’s yearlong effort to enlist conservatives who agree with him as Republican delegates will result in giving him and his views a great deal of influence at the convention and within the party. Similarly, Trump as nominee puts him in a powerful position to influence policy. Meanwhile, the old guard establishment of moderate Republicans who specialized in failure theater and giving Democrats everything they want are not showing up.

So, what will we have? We will have a Republican convention dominated by either Cruz conservatives or Trump outsiders. This is good news, even if I myself am not enthused about Trump. It likely means that the days of nonchalant surrender to liberal demands are ending. Though what will happen instead remains unknown, and might very well be as bad, the change is more likely to be a good thing.

Luxembourg signs deal with asteroid mining company

10:32 am

The competition heats up: As part of its outer space development program, the government of Luxembourg has signed a deal with asteroid mining company Deep Space, Inc. to build an orbital demonstration test satellite.

The inaugural project of this exciting new partnership is Prospector-X™, an experimental, low Earth orbit technology demonstration mission, designed to test the company’s innovative deep space technology. These key enabling technologies will be instrumental to the success of the company’s first deep space resource exploration missions in the near future. The Prospector-X spacecraft will be built at Deep Space Industries’ new European headquarters, in Luxembourg, in conjunction with the company’s international and American partners, including the Interdisciplinary Centre for Security, Reliability, and Trust (SnT) at the University of Luxembourg.

It essentially appears that Luxembourg is creating its own space program, focused entirely on profit by acting as the venture capitalist for private commercial companies. Most interesting.

Cruz’s political stature enhanced by campaign

10:06 am

Good news: Ted Cruz’s strong campaign has positioned him to likely be “a leading GOP voice for the foreseeable future.”

Read it all. The article’s main point, which I had noticed earlier when Cruz was doing the hard work to forge allies throughout the grassroots Republican Party, is that Cruz’s success during the campaign, becoming a strong #2 while all establishment picks (Bush, Rudio, Walker, Huckebee, Christie) did poorly, places him in the position to dominate the loyal opposition against either Trump or Clinton.

Note also that the conventional wisdom, that shutting down the government would hurt a candidate and the Republican Party, did no such thing for Cruz. In fact, it helped him. The anger the public feels because of the Republican Party’s unwillingness to stand up to Obama and the Democrats, was reflected in the fact that in the end Trump and Cruz were the top vote getters.

Sadly, I do not expect the rest of the Republican Senate to learn this lesson.

Obamacare includes 171-word definition of menu

9:54 am

Finding out what’s in it: The Food and Drug Administration has released its final regulations on how restaurants must write their menus as mandated by Obamacare.

The final guidance includes a 96-word definition of “combination meal” and a 163-word definition of “restaurant-type food.” The government also goes into when “Aunt Cora’s French toast breakfast” must have its calories listed and tells restaurants not to use plus or minus signs on their menus because they are too “confusing” to Americans.

But drawing the biggest criticism is the government’s definition of menu and strict rules for calorie labeling of toppings. The government considers a menu to be the “primary writing of the covered establishment from which a customer makes an order selection, including, but not limited to, breakfast, lunch and dinner menus; dessert menus; beverage menus, children’s menus, other specialty menus (such as catering), electronic menus, and menus on the Internet.” The full definition is 171 words. Merriam-Webster has a 12-word definition for menu.

The phrase “from which a customer makes an order selection” opened the door for coupons and advertisements to be included in the mandate. The FDA said calories must be listed on coupons if they have the restaurant’s phone number, and advertisements can be “considered a menu.”

There’s more at the link. Read it all to find out how deeply Obamacare is working to organize and regulate our lives.

But don’t worry. The same people who wrote the law are going to be running things after November. They will surely fix it!

Trump’s new finance chief donates 2x more to Democrats than Republicans

9:37 am

Researching November’s Democratic primary: The man Donald Trump just appointed as his finance chairman routinely donates twice as much to Democrats than he does to Republicans, and has deep ties with the Democratic Party’s most liberal wing.

Beyond his contributions, Mnuchin’s past employers don’t fall in line with Trump’s rhetoric on the campaign trail. Mnuchin is a former Goldman Sachs partner and worked for liberal mega-donor George Soros’s hedge fund. He also contributed to a group called America Coming Together, which was largely funded by Soros and unions.

But don’t worry. We now have two candidates who will fix Obamacare and make sure the foreign policy of the United States is run by the same people that have been doing it for the past eight years.

Putin signs Russian homesteading act

9:26 am

On Monday Russia’s president Vladimir Putin signed a new law that is a variation of the American homesteading acts that helped settle the west in the 1800s.

Trutnev’s initial suggestion was to “create a mechanism for the free allocation of a 1 hectare (2.5 acres) plot of land to every resident of the Far East and to anyone who is willing to come and live in the region so that they could start a private business in farming, forestry, game hunting or some other enterprise.” He added that the agreement could be signed for five years, and then it should either enter full force if the new landlord follows the plan, or be declared void if the land is not used.

They might be doing it wrong in aerospace, but if this story is correct Putin’s government has got it right when it comes to land ownership.

Manager resigns as investigation pinpoints issues during first Vostochny launch

9:02 am

The first head rolls: Even as the investigation into the one day delay for the first Vostochny launch uncovers number of issues, including an incorrectly installed cable, the manager of one division has already resigned.

The problem with a cable made in violation of designer documents delayed the launch of a Soyuz-2.1a rocket from the Vostochny Cosmodrome, the newspaper Izvestia wrote on May 5. “Academician Semikhatov NPO Avtomatiki modeled that situation, saw it with their eyes and certified the results. The rocket’s cable was made in violation of designer documents and lacked a number of vital straps,” a representative of the Roscosmos administration told the newspaper. “Heads of the Yekaterinburg-based NPOA and those responsible for the integrity of methods used in testing the ground control system at the cosmodrome will be definitely held responsible for the contingency,” he said.

They have also found an additional “20 problems”. Expect more heads to roll, which might be a good thing, as it might help fix some of the quality control problems that have become an increasing problem in the Russian aerospace industry.

Problems with nanosat launched from Vostochny

5:48 pm

Of the three satellites launched on the first liftoff from Russia’s Vostochny spaceport, the nanosat is having communication problems.

The problem with establishing a radio contact with the SamSat-218D nanosatellite is caused by its fast spinning, TASS the Samara State Aerospace University that designed the spacecraft told TASS on Wednesday. “When the spacecraft was placed into orbit, it started to spin round too quickly. It has a very little mass – less than two kilograms. As a result, its antenna cannot catch the information, the satellite is rotating rapidly,” the source said.

For Russia this nanosat is the first built entirely by college students, something that U.S. students have been doing for years.
