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!”

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, 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

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.

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.

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.”

The music is “The Most Beautiful Things” by Michael Murphy.

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.

NASA delays asteroid redirect mission one year

8:48 am

NASA has decided to delay by one year the planned launch dates for both its unmanned and manned missions to an asteroid.

And why might you ask?

Mr. Gerstenmaier further stated that “We had trouble getting the funding together for this thing. So this slip of the one year that you see wasn’t caused by technical. It was really caused by budget availability. We just didn’t have the budget available to go do this.”

Also, the article notes that the launch rocket for the unmanned mission, now set for 2021, will be one of three possible rockets.

No elaboration was given as to what those “three rockets” are, though SLS, one of SpaceX’s Falcon family of rockets, and Atlas V are understood to be the prime contenders at this time.

The unmanned mission might happen (though I wouldn’t bet on it). As for the manned mission, there is a reason NASA has had trouble getting funding. SLS/Orion cost too much. Congress simply doesn’t want to spend that much for the actual missions. They will dole out a lot of cash for development (and the pork that goes with it), but even they can’t afford the gigantic budgets NASA needs to actually fly real missions.

Millennials favor GOP, want Clinton imprisoned

11:51 am

There is hope: Despite oversampling Democrats, a new poll shows that millennials now favor the Republican Party, with a plurality calling for Hillary Clinton’s imprisonment.

Among ages 18 to 29, only 36 percent have a favorable view of the Democrat Party, and 47 have an unfavorable view. The low favorability number can likely be tied to young voters who were upset by how the DNC attempted to favor Hillary Clinton over millennial-favorite Bernie Sanders. And, some of these millennials are even saying they view the Republican Party more favorably. The GOP is leading the Democrats by 5 percent, scoring 41 percent favorability. Millennials have the most favorable view of the GOP versus other age demographics.

Later in the poll, we might have found out why: a plurality of millennials believe Clinton should be in prison. In fact, millennials are the only age demographic where more voters believe she should be in prison than those opposed to arresting her. 40 percent of millennials want her jailed, while just 39 percent oppose it (21 percent not sure).

For the past century the Democratic Party has had a lock on young voters. No matter the issue or candidate, voters under 30 routinely voted for Democrats in large majorities. For this poll to show such a trend away from the Democratic Party suggests that maybe the youngest voters are finally waking up to the reality facing them, due largely because of that Democratic Party.

Top IRS officials approved and supervised harassment of conservatives

11:44 am

Working for the Democratic Party: Newly released FBI interviews prove that top IRS officials in Washington, like Lois Lerner and Holly Paz, organized and ran the harassment of conservatives prior to the 2012 election.

The FBI documents also reveal that IRS officials stated that the agency was targeting conservative groups in the summer of 2011 because of their ideology and political affiliation. According to one senior tax law specialist, “The case seemed to be pulled because of the applicant’s political affiliation and screening is not supposed to occur that way … [Redacted] said he thought the cases were being pulled based upon political affiliations.” And IRS senior official Nancy Marks, appointed by Miller to conduct an internal investigation stated, “Cincinnati was categorizing cases based on name and ideology, not just activity.” [emphasis mine]

In others, the evidence shows beyond a shadow of a doubt that the IRS was being used by Democrats in Washington for the express purposed of harassing and attacking their political opponents.

Angara gets a customer

9:47 am

The competition heats up: Russia has signed its first international contract for its new still-underdevelopment Angara rocket.

Leading Russian rocket developer, GKNPTs Khrunichev, signed up the first foreign commercial passenger for the light version of its new-generation Angara rocket. The South-Korean Kompsat-6 remote-sensing satellite (a.k.a. Arirang) was booked for a ride on the Angara-1.2 launch vehicle from Plesetsk around 2020. Equipped with a Synthetic Aperture Radar, SAR, the 1.7 ton spacecraft should be inserted into the Sun-synchronous orbit.

China’s Chang’e 3 finds no water on Moon

9:44 am

The uncertainty of science: After more than 2 1/2 years on the lunar surface China’s Chang’e 3 lunar lander has detected no water at its landing site.

This result, while not in direct conflict with the orbital data from India’s Chandrayaan-1, suggests that the question of water on the Moon is a very complex one. Chandrayaan-1 detected evidence that suggested their might be deposits of water in certain surface regions, locked up in the regolith. Chang’e 3 found no water at its specific location. The two results do not have to conflict, but the latter does raise the uncertainty of Chandrayaan-1’s detection.
