Astronomers photograph an exoplanet

2:14 pm

51 Eridani b

Cool image time! Astronomers have used the Gemini Telescope on Mauna Kea to take the clearest image yet of a Jupiter-sized gas giant orbiting another star 96 light years away.

Once the astronomers zeroed in on the star, they blocked its light and spotted 51 Eri b orbiting a little farther away from its parent star than Saturn does from the sun. The light from the planet is very faint — more than one million times fainter than its star – but GPI can see it clearly. Observations revealed that it is roughly twice the mass of Jupiter. Other directly imaged planets are five times the mass of Jupiter or more. In addition to being the lowest-mass planet ever imaged, it’s also the coldest — about 800 degrees Fahrenheit — and features the strongest atmospheric methane signal on record. Previous Jupiter-like exoplanets have shown only faint traces of methane, far different from the heavy methane atmospheres of the gas giants in our solar system.

All of these characteristics, the researchers say, point to a planet that is very much what models suggest Jupiter was like in its infancy.

The exoplanet is the bright spot near the bottom of the image.

Cassini’s last fly-by of Dionne on Monday

2:05 pm

Dionne

On Monday August 17 Cassini will make its last close fly-by of Saturn’s moon Dionne, dipping to within 295 miles of the surface.

During the flyby, Cassini’s cameras and spectrometers will get a high-resolution peek at Dione’s north pole at a resolution of only a few feet (or meters). In addition, Cassini’s Composite Infrared Spectrometer instrument will map areas on the icy moon that have unusual thermal anomalies — those regions are especially good at trapping heat. Meanwhile, the mission’s Cosmic Dust Analyzer continues its search for dust particles emitted from Dione.

The image of Dionne above is from a June 16, 2015 fly-by, The diagonal line at the top is Saturn’s rings.

After more than a decade, Cassini’s mission is in its final stages. When completed, we will have no way for decades to get close-up images of this gas giant, its spectacular rings, or its many very different moons.

Obamacare forces schools to cut back

11:30 am

Finding out what’s in it: Public school budgets continue to be squeezed by the cost of Obamacare.

They find they either have to cut employee hours, privatize some services, or eliminate health insurance entirely and pay the Obamacare fines. Otherwise, they can’t afford the costs.

This quote however illustrates the educational cost of Obamacare:

School officials say that it’s hard for students to adjust to having multiple part-time educators throughout the day. Chris Johnson, an administrator with the Penn Manor school district in Pennsylvania, told a publication there that, “If you start doing a half day with this person and then a half day with that person, those students don’t react well.”

Even as it bankrupts us financially, Obamacare is also bankrupting us socially. What a disaster. We desperately need to repeal it, as soon as possible.

A look at Ted Cruz’s election strategy

9:36 am

The presidential election: While other candidates trash Rand Paul, Donald Trump, and their supporters, Cruz refuses to do so, taking the high road in the expectation that he will eventually win those supporters when Paul and Trump drop out of the campaign.

As Cruz is quoted in this different article,

“I would … note that an awful lot of Republicans, including other Republican candidates, have gone out of their way to smack Donald Trump with a stick. Now I think that’s just foolish,” he said. Asked why, Cruz paused and then replied, “Donald Trump had a rally in Phoenix, Ariz. [to which] between 10 and 20 thousand people came out. When you attack and vilify the people at that rally as crazies, it does nothing to help Republicans win in 2016. I’d like every single person at that rally to show up and vote in 2016, knock on doors with energy and passion, and turn this country around. If Washington politicians show contempt and condescension to those [voters,] that is a path to losing at the ballot box.”

Though I don’t post much about election campaigns, this does not mean I do not follow them closely. Most of what happens is childish drivel (such as last week’s debate and the big to-do between Trump and Megan Kelly), but if you look for real nuggets of information about the candidates you can find them. These two stories illustrate the cool-headed strength of Ted Cruz. His track record shows he is not afraid to fight, but it also appears he knows how to choose his fights well.

I have liked Scott Walker for the same reasons. In Wisconsin he was willing to fight, but kept a cool head and held back from fighting over petty issues. The problem for Walker now is that he has seemed too cool-headed during the campaign, unwilling to do anything that might offend anyone. This is not going to win elections. Nor is it going to change things even if he should win.

DARPA awards phase 2 space plane contracts

9:05 am

The competition heats up: The second phase contracts in the development of a reusable space plane have been awarded by DARPA.

DARPA has awarded $6.5 million each to three companies for developmental design work, including Boeing (in partnership with Blue Origin), Northrop Grumman (in partnership with Scaled Composites and Virgin Galactic), and Masten Space Science Systems (in partnership with XCOR Aerospace).

The requirements are that the plane fly 10 times in 10 days, reach Mach 10+, put a 3,000 to 5000 pound payload in orbit, and cost less than $5 million per flight. In this new phase, the companies are to deliver finalized designs by 2016, with prototype development to follow.

NASA considers using Bigelow module for deep space missions

8:56 am

The competition heats up: Rather than build something in-house for gobs of money and decades of work, NASA is considering using Bigelow Aerospace’s largest inflatable modules for its deep space missions.

What has happened is that NASA has signed a joint agreement with Bigelow to study the possibility of using Bigelow’s B330 module as a transport habitat on long flights. The agency really has no choice, as it doesn’t have the funding to develop the necessary large spacecraft for these missions, and Bigelow can provide them to it for much less.

This description of the background of Bigelow’s inflatable modules illustrates why NASA can’t build these itself:

The B330 evolved from the Genesis I and II modules that Bigelow Aerospace had launched into space. Those technology demonstrators were born out of the NASA project known as TransHab. The TransHab was an inflatable module designed for the ISS but was ultimately cancelled in 1999 due to budget constraints. The module would have provided a 4 level 27.5 feet (8.4 meter) diameter habitat for the astronauts.

After TransHab was cancelled, Bigelow worked with NASA on a technology transfer, giving Bigelow Aerospace exclusive rights to the technology. Using this technology, Bigelow designed, built and launched two technology demonstrators. They are still on orbit today. Genesis I was launched in 2006 with it’s sister ship launching in 2007. Both ships tested flight operations processes and on-board electronics and have performed above design specifications. [emphasis mine]

Unlike NASA, as a private company Bigelow was able to build this technology quickly and at a low cost. With the new agreement, the goal will be study the operation of a B330 in independent flight in low Earth orbit. Whether an actual B330 will be build and launched however is not yet clear.

The Space Show modernization crowd-funding campaign

12:52 pm

For more than a decade David Livingston has been producing and hosting The Space Show, the aerospace industry’s most important outlet for telling the public what is happening in space.

Now David is starting a crowd-funding campaign to finance a major update to The Space Show archives, in order to make them fully searchable and thus accessible to historians and researchers. As he notes,

Our archives as of this morning contain 2, 524 interview programs. These interviews tell the story of the space industry as many guests were there when it started, when we went to the Moon, and even before SpaceX was started. But as it stands, nobody can search our archives for information, program content, breaking news, etc. The closest one can come to a search is the GuestSearch tool on our current website, but searches are not interactive and about two-thirds of our programs have no key words so a search using the GuestSearch tool is not very useful Space Show archives are a treasure of information and history. By making them fully searchable and of archival quality, everyone benefits, even the casual Space Show listener.

As a space historian, I think David’s effort here is essential. The data hidden in the Space Show archives is invaluable, describing the beginning of the commercial space industry better than any other source. Making it searchable would make this history available to future generations that otherwise would never see it.

Check out the campaign as well as the Space Show support site and contribute. Not only can you help future space historians you will help keep the Space Show on the air.

Contract to build upgraded Vega rocket signed

9:58 am

The competition heats up: The European Space Agency today signed a contract to develop an upgraded version of its Vega rocket.

With respect to the VEGA configuration currently in operation, VEGA C aims to increase the load capacity of the orbital launcher up to 50%. Together with a further increase in operational flexibility, while maintaining its unrivalled orbital precision, it is expected to expand the capability to transport in the same flight a larger number of small satellites, in different orbital planes, or larger satellites. The new version of VEGA will be flight qualified in late 2018 for an entry into service as early as 2019. The group of countries which already participated in the development of VEGA, with Italy playing a major role with a 65% participation, welcomes now the entry of Germany.

I get the impression from this article that Vega is being used by ESA to spread the pork around, since to get Ariane 6 built they had to agree to not do so and give the work and control entirely to Airbus Safran. I thus wonder how competitive Vega will truly be.

Orbital ATK orders second Atlas 5 for launching cargo to ISS

9:43 am

In the heat of competition: Even as it has accepted delivery of two new Russian engines to power its Antares rocket, Orbital ATK has ordered a second Atlas 5 rocket to launch its Cygnus cargo capsule to ISS.

I suspect they want to give themselves some cushion time to test and install these new Russian engines prior to an actual launch. In order to fulfill their contract with NASA, however, they have to launch several times next year, thus requiring more replacements for Antares.

Where is Pluto’s nitrogen coming from?

9:28 am

As New Horizons’ engineers download data and plan future maneuvers to fly past one of two candidate Kuiper Belt objects, the science team today outlined the background mystery of Pluto’s nitrogen.

Pluto’s atmosphere is similar to Earth’s in that it is predominantly composed of nitrogen (N). But Pluto’s atmosphere is ~98% N, while Earth’s is only ~78% N. Pluto’s atmosphere is also considerably thinner than Earth’s with ~10,000 times lower pressure at the surface.

The nitrogen in Pluto’s atmosphere (in the form of N2 gas) is actually flowing away and escaping the planet at an estimated rate of hundreds of tons per hour. We also see what looks like flowing ice on Pluto’s surface in high resolution images made by New Horizons. The water ice (H2O) that we are familiar with on Earth would be completely rigid and stiff at Pluto’s surface temperatures, but ice made out of N2 would be able to flow like a glacier. So where does all of this nitrogen come from?

They have rejected comets as a source, and have predicted that geologic activity on Pluto itself could dredge the nitrogen up from the planet’s interior. (This prediction by the way was made before the New Horizons’ flyby, which has proved it likely.)

If their theory ends up the answer, then they will also prove that Pluto is losing mass, albeit slowly. Nitrogen from within is being processed out of the interior, into the atmosphere as gas, and then into space because Pluto’s gravity is too small to hold it.

Astronomers chart the universe’s slow death

9:40 am

Using data gathered from more than 200,000 galaxies, astronomers have been able to measure the slow decline in the universe’s energy output since the Big Bang.

The fact that the Universe is slowly fading has been known since the late 1990s, but this work shows that it is happening across all wavelengths from the ultraviolet to the infrared, representing the most comprehensive assessment of the energy output of the nearby Universe. “The Universe will decline from here on in, sliding gently into old age. The Universe has basically sat down on the sofa, pulled up a blanket and is about to nod off for an eternal doze,” concludes Simon Driver.

I wish to note the significant uncertainty of this result. While this result is important and does strongly suggest that the universe is dying, 200,000 galaxies is hardly a significant representation of the universe’s galaxy population.

Update on Boeing’s CST-100

8:55 am

This article provides an update on the status of the construction of Boeing’s CST-100 manned capsule.

It also describes NASA’s lobbying effort with Congress to get the full budget it had proposed for the construction of the commercial crew spacecraft.

I note instead the apparent bureaucratic focus of all the work Boeing seems to be doing.

Following the CBR [Certification Baseline Review], Boeing successfully completed the Ground Segment CDR (Critical Design Review) on 4 December 2014 before moving onto the Phase 2 Safety Review (Part B) in early January 2015. By mid-March, Boeing completed the Phase 2 Safety Review (Safety Technical Review Board Readiness) and moved on to the Delta Integrated CDR, which took place on 27 March 2015.

Since then, Boeing has spent the summer months conducting the Phase 2 Safety review (STRB 80%) as well as producing the CDR for the launch elements of the program and the Qualification Test Article Production Readiness Review.

Moreover, in late July, teams at the Kennedy Space Center began building the Structural Test Article (STA) for the CST-100 capsule inside former Orbiter Processing Facility bay 3 (OPF-3).

Lots of reviews, but notice in the last paragraph they have only begun building the first capsule. As much as these reviews might help them make sure they are doing things right, they seem to create a situation where the company is able to slow-walk construction to help NASA with its congressional lobbying effort, while simultaneously making it sound like they are accomplishing a lot.

Sudden outburst activity on Comet 67P/C-G

8:38 am

jet on Comet 67P/C-G

Cool image time! As Comet 67P/C-G approaches perihelion, Rosetta is detecting and imaging more and more activity coming from the nucleus, including a power outburst lasting less than a half hour.

In the approach to perihelion over the past few weeks, Rosetta has been witnessing growing activity from Comet 67P/Churyumov–Gerasimenko, with one dramatic outburst event proving so powerful that it even pushed away the incoming solar wind.

The comet reaches perihelion on Thursday, the moment in its 6.5-year orbit when it is closest to the Sun. In recent months, the increasing solar energy has been warming the comet’s frozen ices, turning them to gas, which pours out into space, dragging dust along with it.

The three pictures above were taken 18 minutes apart. The first shows nothing, and in the last the jet has almost completed dissipated. In the middle image, however, the jet is well defined, and data from the spacecraft indicated that it was so strong that it “had pushed away the solar wind magnetic field from around the nucleus.”

The mobile launch building at Vostochny

8:27 am

At their new spaceport at Vostochny, the Russians are building a moveable launch building that will enclose their Soyuz rockets prior to launch.

Painted in elegant blue and white and standing almost 50 meters high, the Mobile Service Tower, MBO (for Mobilnaya Bashnya Obsluzhivaniya), is designed to provide personnel access to the Soyuz rocket during the countdown to liftoff from its launch pad in Vostochny. The structure can be also used to service the pad after launch and to process the rocket in case of an aborted liftoff.

With the tower in place, technicians can easily reach practically any part of the rocket as high as 37 meters above the surface of the launch pad. Internal access bridges of the tower surround the upper portion of the first and second stage, the third stage and the payload fairing.

The article also notes that “for decades, Soviet soldiers and officers and later their Russian civilian successors had to brave winter cold and summer heat preparing Soyuz rockets for launch on open-air gantries in Baikonur and Plesetsk. But in a sign how times have changed, the new generation of rocketeers will be protected from snow and rain with a climate-controlled tower completely enclosing the Soyuz rocket before liftoff from its newest launch pad at Russia’s Vostochny Cosmodrome.”

The irony here is profound. Big moveable buildings is how NASA has been doing it since Apollo. It is also what Boeing’s Delta family of rockets uses at Vandenberg in California. It is also why the Saturn 5 was and the Delta is so expensive to launch.

SpaceX abandoned such complicated structures in designing its Falcon 9, and instead decided to copy the old Soviet method of simple buildings for horizontal assembly and the simple horizontal transport to the launchpad. This appears to save a lot of money while simplifying rocket assembly.

That the Russians are now copying NASA’s more expensive but fancy mobile building approach means that, once again, their government is making decisions not based on efficiency but the prestige their political decisions can give them. From a competitive perspective, this is not going to benefit the Russia space effort, in the slightest.

But their workers will be more comfortable while they assembly those rockets!

Mauna Kea visitor center reopens

5:47 pm

The visitor center on Mauna Kea was reopened this weekend after a month closure that supposedly forbid access by the public.

And yet, for that entire month, the state has allowed the protesters opposing construction of the Thirty Meter Telescope (TMT) to remain camped across the street.

To me, this illustrates where the state’s loyalties lie. They might talk a tough game, but they are really doing nothing to enforce the law and the legally negotiated agreements between the astronomical community and the various Hawaiian cultural institutions that had agreed on the conditions for building TMT. By allowing the protesters to continue to break the law and set up house on the mountain, the state is saying they really want construction to cease.

I say, maybe the time has come for astronomers to agree, and move lock, stock, and barrel south to Chile. In addition, maybe tourists should consider other places to visit, rather than a place that exhibits such hostility to outsiders.

Houston trying to steal land from two churches

2:09 pm

Fascists: Having failed to intimidate religious leaders when the city of Houston tried to subpoena their sermons, the city is now trying to use eminent domain procedures to shut down two churches.

The fifth ward is located just outside of downtown. Property values in the area have skyrocketed and continue to climb. The City of Houston offered to purchase the churches. When the churches refused, the city came back with threats of using eminent domain to acquire the property as part of an urban development plan.

More here. Texas state law, written and passed after the Supreme Court decision in Kelo v New London, expressly forbids this kind of eminent domain taking. Moreover, the taking appears to specifically violate the first amendment rights of these two churches.

Quick! Guess what to which political party the Houston mayor belongs!

Scientists narrow the next Mars rover candidate landing sites to 8

9:13 am

Jezero Crater

For the next Mars rover, scheduled to launch in 2020, scientists have now narrowed their candidate landing sites to eight, with Jezero Crater (pictured on the right) the favorite choice.

The top vote getter was Jezero crater, which contains a relic river delta that could have concentrated and preserved organic molecules. “The appeal is twofold,” says Bethany Ehlmann, a planetary scientist at the California Institute of Technology (Caltech) in Pasadena. “Not only is there a delta, but the rocks upstream are varied and diverse.”

The image clearly shows the scientific attraction of Jezero Crater, with an obvious meandering river canyon opening out into an obvious river delta. The crater in the delta will also give them an opportunity to do some dating research, since that crater had to have been put there after the delta was formed.

The choice however illustrates the difference in goals between scientists and future colonists. Scientists are looking for the most interesting locations for understanding the geological history of Mars. Future colonists want to find the best places to establish a home. Jezero Crater, as well as the other eight candidate sites, do not necessarily fit that settlement need. For a colonist it might be better to put a rover down on the flanks of Arsia Mons, one of Mars’ giant craters where scientists have evidence of both water-ice and caves. None of the candidate sites, however, are aimed anywhere close to this volcanic region, because scientifically it is not as interesting.

This is not to say that the candidate sites might not be good settlement sites. It is only to note that the focus of these scientists is research only. Furthermore, it is probably premature anyway to look for settlement sites. We need to know more about Mars itself.

Stratolaunch shifts to the small sat market

5:07 pm

The competition heats up: Even as Vulcan Aerospace, the company building the Stratolaunch air-launch system, considers its options for the second stage rocket that it will use, it has decided to shift its focus towards the small satellite market, including cubesats.

In a sense, they are now aiming at the same cubesat/smallsat market that Virgin Galactic wants with its LauncherOne air-launched rocket. Whether they can build a system cheap enough for these small satellites to afford, however, remains the big question. Their shifting focus, like Virgin Galactic’s, does not bode well for them.

Stratolaunch of Huntsville, Alabama, has already gone through two earlier iterations of its launch vehicle. When Stratolaunch unveiled its plans in December 2011, it planned on using a variant of SpaceX’s Falcon 9 rocket. Less than a year later, though, Stratolaunch announced it was ending that agreement because SpaceX wanted to focus on the standard version of its Falcon 9.

Stratolaunch then teamed with Orbital Sciences Corp., now Orbital ATK, to develop a launch vehicle. That rocket, called Thunderbolt, featured two solid-fuel stages provided by ATK and an upper stage powered by RL-10 engines from Aerojet Rocketdyne. Like the earlier SpaceX design, Thunderbolt was designed to launch medium-class payloads.

Stratolaunch, though, has set that design aside as it seeks to launch smaller satellites, where the company sees a burgeoning market.

One wonders if the cost of building Stratolaunch will be more than this smallsat market can bear.

The bog bodies of Europe

3:37 pm

Link here. The peat bogs preserve the bodies, providing scientists a window into the past. However, the bodies exhibit one mysterious tendency: violent death.

Since the 18th century, the peat bogs of Northern Europe have yielded hundreds of human corpses dating from as far back as 8,000 B.C. Like Tollund Man, many of these so-called bog bodies are exquisitely preserved—their skin, intestines, internal organs, nails, hair, and even the contents of their stomachs and some of their clothes left in remarkable condition. Despite their great diversity—they comprise men and women, adults and children, kings and commoners—a surprising number seem to have been violently dispatched and deliberately placed in bogs, leading some experts to conclude that the bogs served as mass graves for offed outcasts and religious sacrifices. Tollund Man, for example, had evidently been hanged.

Read it all. It is a fascinating combination of history, archeology, and forensics.

Russia delivers to Orbital ATK the first two new Antares engines

9:15 am

Even as Orbital ATK begins to wrap up their investigation into the October launch failure of their Antares rocket, Russia delivered on July 16 the first two new replacement engines.

The RD-181 motors will be used in the first stage of the rocket. They will replace aging AJ-26 engines the company decided to stop using after one of them exploded during a launch last October. The AJ-26s are revamped NK-33 engines left over from the Soviet Union’s manned lunar program.

The first launch of the revamped Antares booster is set for next March. The rocket will carry a Cygnus cargo ship bound for the International Space Station.

Though these Russian new engines will allow Orbital to get Antares back into operation, they do limit that rocket’s marketability in the U.S.

Finger Rock Fire update

8:57 am

During the night the fire seemed to subside somewhat, and today it is raining. I can still see smoke, but no flames. However, the cloudy weather, plus morning is a poor time of day to observe details in the Santa Catalinas because of the angle of the sun, means that this is not a certain observation.

The Forest Service has sent crews up to check on the situation and will report an update later this morning. This news report says nothing about the fire spreading into Ventana Canyon, as it appeared to do to me last night. Hopefully I was wrong and the fire only appeared larger than it was.

Auschwitz commandant outraged over Mengele video

10:10 pm

Heh.

Rudolph Hoess, family man and commandant of the Auschwitz-Birkenau concentration camp, has been desperately trying to restore the camp’s reputation after some damaging remarks by one of its doctors, Joseph Mengele, were caught on tape and posted online.

Dr. Mengele, who oversees medical services at the camp, was recorded casually speaking of a girl who was suffering complications as a result of HitlerCare. The girl, Eva Mozes Kor, complained of fever, trembling, and swollen limbs that resulted from a series of five free government-funded injections. Mengele is seen on the tape laughing off the matter saying, “Too bad she is so young. She has only two weeks to live.”

To Hoess, such behavior is unacceptable. “I want to be clear,” said Hoess, “that I find the tone of Dr. Mengele’s remarks inappropriate, and that he has been properly reprimanded. Furthermore, I wish to emphasize that nobody on the staff at this concentration camp in any way profits from the clothing, valuables, cash, and gold fillings that are reallocated from our guests. While some evidence, which was tragically burned, may have indicated an occasional impropriety, we nevertheless pride ourselves in offering compassionate care at this facility, no matter what.”

Read it all. His outrage at the way the video was obtained will tell you who the real villains are in this story. How dare someone slander the reputation of these fine individuals!

NASA extends Russian crew ferry contract through 2019 for $490 million

8:09 pm

Lobbying Congress: Claiming that the unwillingness of Congress to fully fund its effort to build commercial manned space ferries, NASA announced today that it has extended its contract with the Russians through 2019, at a cost of $490 million.

For the next fiscal year, House Republicans have proposed allocating nearly $250 million less than the request, while Senate Republicans would offer $300 million less. If Congress doesn’t increase the allocation, Boeing and SpaceX likely will receive orders to immediately suspend all operations either next spring or summer, Bolden said. And if those orders are issued, Bolden said the existing contracts “may need to be renegotiated, likely resulting in further schedule slippage and increased cost.”

According to this article, the extension has also increased the cost per astronaut flight from $71 to $82 million.

The irony here is that I do not believe Congress’s cuts to this program have slowed SpaceX’s effort down in the slightest. I expect that, barring more flight failures or orders from NASA to stop work, they could fly their first manned Dragon flight by 2017.

Boeing however is probably dragging its feet, since it really isn’t that much interested in achieving manned flight as much as squeezing cash out of Congress. It is probably thus eagerly working with NASA in this lobbying effort.

Meanwhile, the Republican idiots in Congress are claiming — falsely — that these cuts are forced on them by sequestration. This is a lie, as they have, at the same time they have cut commercial crew, increased the budget for SLS. If they were really interested in serving the needs of the nation they would have cut SLS, which can’t accomplish anything and is a terrible waste, and sent the money to commercial crew instead.

But then, who said they were interested in serving the needs of the nation? It doesn’t appear that way to me.

TMT protesters gather outside IAU conference in Hawaii

4:20 pm

Two quotes from the article I think clarify what is going on here. First, one of the protester signs illustrated very clearly the level of ignorance and foolishness of the protesters;

“We don’t want your big toy telescopes on our sacred mountain.”

Then there was this significant point noted in the article:

The demonstrators are a diverse group but are generally led by men and women in their twenties who were educated in modern Hawaiian-language immersion schools. Decades ago, children were beaten for speaking the language; today it is a source of cultural pride and a touchstone for Hawaii’s burgeoning sovereignty movement.

In other words, for the past few decades the public schools in Hawaii have been focused on teaching young Hawaiians to hate American culture and whites. Instead, race and ethnicity come before concepts of freedom and individual rights. How nice. (If you don’t believe me spend just a little time studying what these native peoples courses teach. I’ve seen it here in Arizona as well as in New York. They really do teach anti-Americanism and a hatred of whites.)

However, considering that Hawaii has been controlled exclusively by leftwing Democrats for decades, no one should be surprised.

Curiosity looks ahead at its future travels

2:17 pm

The future terrain at Mt Sharp

Cool image time! The above image is a cropped version of a full resolution image taken by Curiosity of the terrain the rover will be traveling in the coming years.

I have also enhanced the contrast slightly to bring out the details. The terrain is rugged and very diverse, from rounded buttes to rocky outcrops.

Gravel and sand ripples fill the foreground [not shown in my cropped version above], typical of terrains that Curiosity traversed to reach Mount Sharp from its landing site. Outcrops in the midfield are of two types: dust-covered, smooth bedrock that forms the base of the mountain, and sandstone ridges that shed boulders as they erode. Rounded buttes in the distance contain sulfate minerals, perhaps indicating a change in the availability of water when they formed. Some of the layering patterns on higher levels of Mount Sharp in the background are tilted at different angles than others, evidence of complicated relationships still to be deciphered.

Traversing this rugged terrain will be a challenge but it is necessary to obtain data that will help decipher its origins. The immediate goal will be to reach the light brown terrain in the distance. In the full image, that region gently slopes upward to the left to the mountain summit, providing a route to the rover’s eventual goal.

Texas government officials kidnap 11 children illegally from parents

9:29 am

Fascists: Because of a single false report to Child Protection Services (CPS), government officials illegally kidnapped the eleven children from their parents, and are now imposing their rule on the family.

The mother was in the hospital for three days being treated for pancreatitis. During that time period, her husband came to visit twice, bringing their youngest baby with him while leaving the remaining kids under the care of the oldest kids, 16, 14, and 12 years old, a perfectly reasonable thing to do. Members of a church the family formerly attended reported this to CPS. CPS then lied to a visiting judge, claiming the children had been left alone for three days, in order to get the court order to remove them. Moreover,

The order for the removal of the children was signed by visiting Judge Curt Henderson, while the sitting judge was on vacation. The sitting judge had reportedly previously denied the removal. According to protocols, the visiting judge reportedly should not have signed the emergency removal order without notifying the parents’ attorneys first. The apparent violation is believed to be the reason that the children were returned home.

In addition, they now have less than a week to find a new place to live.

They also have to find a house to move to, and move, by August 8, because a police officer who accompanied the social worker decided to phone the Rembis’ landlord and allegedly accused them of violating their lease. They received the eviction notice the day after the children were seized. When no lease violations were found, the landlord reportedly decided not to renew their lease. They still have to move. [emphasis mine]

Worse, even though the removal was illegal, CPS now has its claws in the family. If the parents do not do exactly as the government demands it will then steal the children again, and will be in a better position to make that removal stick.

Read the whole story. It will make you ill.

Airbus patents design for a supersonic ramjet airplane

8:55 am

The competition heats up: Two Airbus engineers have gotten a patent for a supersonic jet that would use suborbital space engineering, including hydrogen-oxygen engines as well as a ramjet, to fly at 20 to 30 miles elevation.

On a typical flight, it would take off like a conventional plane using ordinary turbojet engines, but once in the air, an open door in the stern of the plane reveals a rocket motor. When this fires, it sends the aircraft into a near vertical trajectory, accelerating it to supersonic speeds.

As the airplane approaches Mach one, the turbojets shut down and retract into the fuselage. On completion of the acceleration phase the plane is now flying at anywhere from Mach 4 to Mach 4.5 at an altitude of 30,000 to 35,000 m (100,000 to 150,000 ft). The rocket motor shuts down and is again concealed as the aft door slides shut to reduce drag. A ramjet now kicks in and the aircraft cruises along its flight path and can cover a range of 9,000 km (5,600 mi) in three hours – the equivalent of Tokyo to Los Angeles or Paris to San Francisco. Meanwhile, the wing fuselage design dissipates the sonic shock wave over 110 to 175 km (68 to 109 mi) and angles it at 11 to 15 degrees so it doesn’t reach the ground. At the end of the journey, split flaps reduce speed and the turbojets take over for approach and landing.

As the article notes, it is unlikely this jet will ever be built, as patented. The patent however illustrates the growing interest by commercial operators of these radical aerospace designs. While this specific design might never fly, many aspects of it are going to start appearing in flying ships in the next few decades.
