Cruz visits NASA

8:46 am

In taking his family on a tour of the Johnson Space Center, Senator Ted Cruz (R-Texas) also met with some local industry businessmen where he expressed support for NASA as well as a desire to get ISS extended to 2028.

Cruz did not take questions from the media, though they were present during the meeting with businessmen. In reviewing the local press reports of that meeting (of which the above link is the most detailed), it appears that Cruz was mostly there to firm up his local constituent support by mouthing vague but strong support for NASA. It also appears that he as yet does not have a clear understanding of NASA’s full circumstances, or if he does he is leaning down the pork road to gain votes.

When my policy paper appears I intend to make sure his office gets it. By his actions after that we shall then see how sincere Ted Cruz really is about fiscal responsibility and private enterprise.

A big Perseid meteor shower on Friday?

8:29 am

According to a new computer model of the Perseid meteor shower, astronomers predict that there could be a big peak of shooting stars on Friday.

Russian astronomer Mikhail Maslov and Finnish astronomer Esko Lyytinen predict that this year the Earth will pass through a stream of cometary material shifted towards us by Jupiter’s gravitational field. According to their model, and work by French scientist Jeremie Vaubaillon, we could see a steep rise in activity from late evening on 11 August to 0500 BST on 12 August.

The Perseids are typically active from around 17 July to 24 August, although for most of that period only a few meteors an hour will be visible. During the peak, and if the predictions by Maslov, Lyytinen and Vaubaillon are right, as many as 100 meteors or more may be seen each hour. This year, the light from the waxing gibbous Moon will interfere to some extent for the first part of the night, so observers are advised to look out in the early morning hours after midnight when the Moon is very low in the sky or has set.

If this is true, Diane and I might have lucked out, as we will be heading for our annual Grand Canyon hike to the bottom on Friday.

NASA finalizes more cubesat deals for first SLS launch

11:19 pm

Lockheed Martin and NASA have signed a deal to put a science cubesat on the first SLS rocket, planned for an unmanned launch of Orion in 2018.

The adapter ring that connects Orion to the rocket will include 13 bays for CubeSats, shoe-box sized payloads that until now haven’t been delivered in significant numbers into deep space. Each of those payload operators is working to finalize contracts with NASA for the ride into space, and on Monday, Lockheed Martin announced a few details of its 6U CubeSat, called SkyFire. Lockheed’s payload will capture high-quality images of the Moon. And in exchange for the ride into deep space, NASA will receive data from the mission.

“The CubeSat will look for specific lunar characteristics like solar illumination areas,” James Russell, Lockheed Martin SkyFire principal investigator, said in a news release. “We’ll be able to see new things with sensors that are less costly to make and send to space.”

This is without doubt a great opportunity for Lockheed Martin and others to test the use of a cubesat in interplanetary space. Whether it makes sense to use SLS to launch them is another matter entirely.

The mystery of Tabby’s Star deepens

11:15 pm

The uncertainty of science: New data from Kepler has made it even more difficult for scientists to explain the strange fluctuations and dimming of Tabby’s Star.

KIC 8462852, as it is more properly known, flickers so erratically that one astronomer has speculated that nothing other than a massive extraterrestrial construction project could explain its weird behaviour. A further look showed it has been fading for a century. Now, fresh analysis suggests the star has also dimmed more rapidly over the past four years – only adding to the enigma. “It seems that every time someone looks at the star, it gets weirder and weirder,” says Benjamin Montet at the California Institute of Technology, who led the study.

There are as yet no natural explanations for the star’s dimming.

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.

Sunspot ramp down continues

9:36 am

Below is NOAA’s monthly update of the solar cycle, posted by them on August 7. It shows the Sun’s sunspot activity in July, with annotations.

July 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.

As expected, there was a recovery in sunspot activity in July compared to June. Also as expected, the recovery was not significant, so that it appears, based on the past two months, as if the ramp down to solar minimum is accelerating so that solar minimum will occur sooner than expected, possibly as soon as two years.

I would not put much stock on that prediction, however. When sunspot activity first reached this level during the past solar cycle in late 2005, it still took three more years before solar minimum was reached. If this cycle matches the last, that would mean that this cycle, from minimum to minimum, will have lasted 10 years, making a short solar cycle though not one of the shortest. However, it is more likely that the ramp down will stretch out, as it usually does, gliding downward to solar minimum in a slow gentle curve that makes for a full cycle of about 11 years.

Trump reveals economic policy team

5:26 pm

Donald Trump has unveiled his list of economic advisers.

The list is quite varied, with some very conservative individuals (Steven Moore of the Heritage Institute for example), a good number of former Reagan administration officials, a bunch of middle-of-the-road businessmen, and at least one past Hillary Clinton contributor (Steven Mnuchin). Overall, this list once again suggests that a Trump administration will be moderate though lean right, while also favoring business. It also suggests that Trump’s administration will not be as reform-minded as he sometimes claims. Instead, it suggests that while Trump will push through some much needed reforms, his administration will mostly work to try to fix the status quo.

Will that be good for the country? Right now, considering the dire state of the federal government’s budget and the general corruption that increasingly seems to permeate its entire operation, I personally don’t think so. Strong and fearless reform is needed badly, and it looks like the Trump administration won’t really give us that. However, this list of advisers also suggests that a Trump administration will possibly include some positive change, and also be far less harmful than a Clinton administration, which will push to do more of the very things the federal government has been doing so badly during the past two decades.

New evidence suggest lake once existed in Gale Crater

8:53 am

Scientists have concluded that mineral veins seen by Curiosity in Gale Crater were created when a lake existed there.

The study suggests that the veins formed as the sediments from the ancient lake were buried, heated to about 50 degrees Celsius and corroded. Professor John Bridges from the University of Leicester Department of Physics and Astronomy said: “The taste of this Martian groundwater would be rather unpleasant, with about 20 times the content of sulphate and sodium than bottled mineral water for instance!”

Poll shows Hawaiians strongly favor TMT

11:14 pm

A new poll shows that by a 2 to 1 margin Hawaiians are in favor of building the Thirty Meter Telescope (TMT).

  • 89 percent of Hawaii Island residents agree there should be a way for science and Hawaiian culture to co-exist on Maunakea
  • 76 percent of Hawaii Island residents agree that TMT will help create good paying jobs and economic and educational benefits for those living on Hawaii Island
  • 70 percent of Hawaii Island residents agree that failure to move forward with TMT will hurt educational opportunities for Hawaii Island children with the termination of TMT’s annual $1 million contribution to the THINK Fund and workforce pipeline program
  • 69 percent of Hawaii Island residents agree that TMT has followed a lengthy approval process, so work should proceed

Based on what I’ve seen for the past forty years, this poll will mean nothing. The poll also found that the native Hawaiian population was much less supportive, with only 46 percent in support of the project and 45 percent opposed. And since the Democratic Party that runs Hawaii is a party that cares almost exclusively for the concerns of oppressed minorities over that of the non-native majority, you can bet they will do what the native population wants. The telescope will never get built in Hawaii, and the consortium building TMT had better face this reality and find another location.

Three stops on Iceland’s golden circle

6:01 pm

An evening pause: From the youtube webpage: “The three main stops on the Golden Circle route in Iceland: 1. The magnificent Gullfoss waterfall; 2. Haukadalur geothermal area (widely known as Geysir) – famous for its geysers and termal pools (Strokkur being the most active); 3. Thingvellir National Park, where the Icelandic Parliament was established in 930, and where the continental drift between Europe and North America can be easily noticed.”

Another reason to avoid Windows

1:33 pm

For once, this post is not a link to another Windows horror story. Instead, it is a link to a great deal to buy CrossOver 15, the professional version of Wine that allows you to run Windows software on Linux or Apple computers. Normally CrossOver costs $59.99. This deal sells it for $19.99. And the sale ends in one day!

So, if you were thinking of trying Linux but were hesitating because you were unsure about whether you could run Windows software on it, this helps solve the problem. CrossOver does what WINE does, but with full telephone support.

I must add one more thing for full disclosure: If you buy it through the link above, you will also help support Behind the Black, as I will get a credit for the referral. I’m doing this not for that credit but because I think this is definitely a good deal. However, why not get the referral at the same time?

Note that the link above doesn’t take you directly to the CrossOver 15 deal. Click on Categories, then Software. You will see the CrossOver deal link in the second row.

SDO not returning data

8:55 am

For reasons that remain unexplained, the Solar Dynamics Observatory (SDO) did not return to science mode after it passed through the Moon’s shadow on August 2nd.

The only information about this on the SDO webpage simply states, ” The spacecraft did not go back into Science mode at the end of the transit. SDO FOT members are looking into the issue.” Spaceweather.com notes that “Since the transit no new data have appeared on SDO public websites.”

SDO has only been in orbit for six years. It would be a shame to lose it so quickly.

UPDATE: It appears that engineers are getting SDO back into operation. Hat tip James Fincannon.

North Korea’s space goal: Hit the Moon in five years

8:20 am

The competition heats up? According to one North Korean official, that country’s goal in space is to put a spacecraft on the Moon sometime in the next five years.

I actually believe this official. Their dear leader has demanded this, and they are sincerely trying to do it. Since they have had enormous trouble simply launching short range ballistic missiles, I have serious doubts they will make it happen, at least within five years.

Moon Express gets FAA approval for Moon landing

2:59 pm

The competition heats up: Moon Express, one of the leading private competitors in the Google Lunar X-Prize, has gotten FAA approval for its planned 2017 Moon landing.

It is looking like 2017-2018 will be very exciting years for private space. We will not only see the first launches of privately-built manned spacecraft, we will see the first privately-built and -funded missions to both the Moon and Mars.

The interior of Ceres

11:06 am

Using data from Dawn, scientists have created their first rough map of the internal structure of Ceres.

The data indicate that Ceres is “differentiated,” which means that it has compositionally distinct layers at different depths, with the densest layer at the core. Scientists also have found that, as they suspected, Ceres is much less dense than Earth, the moon, giant asteroid Vesta (Dawn’s previous target) and other rocky bodies in our solar system. Additionally, Ceres has long been suspected to contain low-density materials such as water ice, which the study shows separated from the rocky material and rose to the outer layer along with other light materials. “We have found that the divisions between different layers are less pronounced inside Ceres than the moon and other planets in our solar system,” Park said. “Earth, with its metallic crust, semi-fluid mantle and outer crust, has a more clearly defined structure than Ceres,” Park said.

Scientists also found that high-elevation areas on Ceres displace mass in the interior. This is analogous to how a boat floats on water: the amount of displaced water depends on the mass of the boat. Similarly, scientists conclude that Ceres’ weak mantle can be pushed aside by the mass of mountains and other high topography in the outermost layer as though the high-elevation areas “float” on the material below. This phenomenon has been observed on other planets, including Earth, but this study is the first to confirm it at Ceres.

In other words, Ceres behaves more like a semi-hardened blob of jello than a rock.

3rd largest insurer begins retreat from Obamacare

10:14 am

Finding out what’s in it: Aetna, the nation’s third largest health insurer and faced with $300 million in loses, has decided against expanding its participation in the Obamacare exchanges.

They also announced that they are re-evaluating their entire participation in the remaining exchanges.

In related news, Obamacare rates are likely to go up from 23% to 45% in Illinois, and 17.3% in Michigan.

But don’t worry, we’ve got the situation covered. We’re going to vote for Hillary Clinton and Democrats, the people that gave us this failed law. They’ll surely fix it!

“News Media Now Giving Trump the ‘Full Palin.’”

9:57 am

Working for the Democratic Party: The expected full-media assault on the Republican Party candidate has begun. As the author at the link notes,

There have been few conservatives who have been more critical of Trump since the start of this insane campaign than me, and he deserves every bit of condemnation he has gotten for needlessly mishandling the Khan situation. However, there is also no doubt that the media became obsessed with the story because they want Trump to lose, got a bit freaked out about his very temporary convention bounce, and smelled blood.

Hillary, while she is less likely to be stupid enough to so publicly take on the parents of a fallen war hero, would also never have been lured by the media into the conflict to the extent Trump was. If she had somehow stepped in it, the news media would have let it go far sooner than they did for Trump (for instance, how many voters are even aware of the controversy over her basically calling some family members of Benghazi victims liars?).

This story has seemed to open the floodgates now on Trump in much the same way that the infamous Katie Couric interview did with regards to Sarah Palin in 2008. Now, everything Trump says seems to be instant fodder for the media’s intensified “gaffe watch.”

It is very important to recognize one more additional fact: Any Republican candidate would have been treated this way by the now openly partisan and decidedly bankrupt mainstream media. The question now is whether the low-information public has finally become aware of this game.

Design problems for Starliner

4:49 pm

In the heat of competition: Boeing is working to correct two serious design problems that cropped up during the construction of its Starliner manned capsule.

First the thing was weighing too much:

One issue involved the mass of the crew capsule, which outgrew the lift capability of the United Launch Alliance Atlas 5 rocket selected to put it into orbit. The CST-100 Starliner will ride an Atlas 5 rocket with two solid rocket boosters and a dual-engine Centaur upper stage, and although Boeing and ULA engineers considered adding a third strap-on motor to compensate for the capsule’s extra weight, managers now have the spacecraft back under its mass allowance, Ferguson said.

Second, the capsule has a shape problem:

Ferguson said Boeing has a model of the Atlas 5 rocket and CST-100 Starliner in a wind tunnel to verify a change to capsule’s outer shape devised to overcome higher-than-expected aerodynamic launch loads discovered in testing. “They had one issue, a non-linear aerodynamic loads issue, where they were getting some high acoustic loads right behind the spacecraft,” said Phil McAlister, head of NASA’s commercial spaceflight development office in Washington.

Something here is rotten. It seems to me that Boeing shouldn’t be having these very basic problems right off the bat. In the past, under the older cost-plus contracts NASA used to routinely hand out, these kinds of problems would simply have meant that Boeing would have gotten more money from NASA, This time, however the contract is fixed-price. If Boeing has problems or delays, the company will have to bear the cost, not NASA. I suspect these problems might have occurred because of some cultural laziness at Boeing. Their management is used to not having to eat the cost of these kinds of mistakes. Now, they will. I expect the culture to therefore begin changing.

Io’s atmosphere freezes and reinflates daily

9:47 am

New data from the ground-based Gemini telescope suggests that Io’s sulfur dioxide atmosphere freezes and then reinflates each time the moon flies through Jupiter’s shadow.

A study led by SwRI’s Constantine Tsang concluded that Io’s thin atmosphere, which consists primarily of sulfur dioxide (SO2) gas emitted from volcanoes, collapses as the SO2 freezes onto the surface as ice when Io is shaded by Jupiter. When the moon moves out of eclipse and ice warms, the atmosphere reforms through sublimation, where ice converts directly to gas.

The data is somewhat uncertain, however, as it based on only two observations.
