Human etchings half a million years old?

3:39 pm

The uncertainty of science: Did an ancestor of humanity etch zig-zags on a shell half a million years ago?

This story is a fascinating illustration of the difficulties of pinning down facts in the field of science. The researchers do an impeccable job of checking all possibilities, and finish by cheerfully admitting that their conclusions could be wrong. If right, however, the discovery is significant, as it tells us that 500,000 years ago an ancestor of the human race was capable of drawing an abstract design on the surface of a shell.

Orion launch on Thursday given go-ahead

1:30 pm

The Thursday test launch of an Orion capsule has been given the go-ahead.

Many of the news reports this week about this test flight have referred to Orion as “the spacecraft that will take humans to Mars.” I must note again that this is hogwash. No humans will ever go to Mars using Orion. It is too small and does not have the capacity to keep humans healthy and alive for the year-plus-long flight time necessary to get to and from Mars.

The most Orion can ever be is the ascent and descent module for a much larger interplanetary space vessel, used just for getting humans up and down from the surface of the Earth. The spacecraft that will really take people to Mars will have to be something more akin to Mir or ISS, a large assembly of modules put together in low Earth orbit.

One other tidbit everyone should know about tomorrow’s test flight: Though it is being touted as a test of Orion’s heat shield, the company that makes this heat shield has already abandoned this design, so the test itself is for a heat shield that will never be launched again on another Orion capsule. In addition, the flight won’t test the rocket to be used, as the SLS rocket isn’t ready. Nor will it test the capsule’s life support systems, which are not on board.

Which immediately raises the question: Why in hell is NASA even bothering with this test flight?

Sadly, I can answer that question. This is all public relations, an effort to lobby for funding. That’s it.

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 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.

Organic material from Mars?

12:55 pm

The uncertainty of science: Scientists theorize that the carbon material found in a 2011 meteorite could be Martian biological material.

Ejected from Mars after an asteroid crashed on its surface, the meteorite, named Tissint, fell on the Moroccan desert on July 18, 2011, in view of several eyewitnesses. Upon examination, the alien rock was found to have small fissures that were filled with carbon-containing matter. Several research teams have already shown that this component is organic in nature. But they are still debating where the carbon came from.

Chemical, microscopic and isotope analysis of the carbon material led the researchers to several possible explanations of its origin. They established characteristics that unequivocally excluded a terrestrial origin, and showed that the carbon content were deposited in the Tissint’s fissures before it left Mars.

Postgraduate plug-n-play cubesat manufacturers ship their first product

9:07 am

The company for cheaply mass-producing cubesats and their components — formed by two brothers while attending college last year — has shipped its first product.

RadioBro, the company founded by Mark and Eric Becnel, reached its first product milestone with a mini-satellite communications transceiver. “We prototyped it in June and did a production run,” says Mark Becnel, company president, who is also finishing up his aerospace engineering master’s degree at UAH. His brother, Eric, who is RadioBro vice president and chief engineer, graduated in 2013. “We accomplished some pre-sales and then did a full run of 100 units,” Becnel says. The MiniSatCom is offered in a variety of kits.

They now are developing a cubesat core that

will save cubesat developers the six months to two years of development time that’s normally required to make a disparate stack of various products work together to serve the same function, Becnel says. If the cubesat is built to generally accepted standards, the core will be plug and play, he says.

These guys have the right idea for space development. Instead of looking for jobs with other companies or NASA, they found a need in the aerospace industry and are filling it, cheaply and efficiently and thus saving everybody time and money. The result: They make money themselves selling their product.

The failure of single payer government health plans

8:10 am

Link here. Read it and be warned. Many Democrats, faced with the complete disaster of Obamacare, like to claim that none of those problems would have happened if they had instead imposed a single payer plan (a euphemism for nationalizing healthcare under a government run system).

Well, read the article at the link. It will give you an idea what to expect under nationalized healthcare, and it ain’t good.

An aside: I despise the term “single payer,” as it attempts to hide the fact that the proposal is nothing more than the nationalization of healthcare, which puts the government in control. No journalist should use it, and if they do, they should either make it clear what it means, or they reveal themselves to be leftwing hacks.

Europe agrees to build Ariane 6

8:01 am

The heat of competition: Faced with a stiff challenge from SpaceX, the European partners in Arianespace have worked out a deal to replace the Ariane 5 rocket with Ariane 6.

The official announcement will be made in next few days, but with Germany agreeing to the French proposal, the partnership can now proceed.

The result will be a government rocket which will likely only launch government payloads, since it will likely also cost too much to compete with SpaceX and the other new lower cost commercial companies like Stratolaunch, now developing in the U.S.

Chinese spacecraft reaches L2

10:13 am

The service module for China’s test lunar probe, that circled the Moon before returning to Earth, has reached L2 as planned.

As of Friday, the service module had been flying for 28 days, and was 421,000 kilometers away from Earth and 63,000 km from the moon. All experiments are going well. The service module was separated from the return capsule of China’s test lunar orbiter, which returned to Earth on Nov. 1 after circling the moon in its eight-day mission launched on Oct. 24.

…After two orbital transfers, the service module re-entered the elliptical orbit with an apogee of 540,000 km and a perigee of 600 km. During the flight, the service module again performed orbital transfer actions twice, and flew along the pre-set Earth-moon transfer orbit. On Nov. 23, it reached the perilune and with the lunar gravity it was able to undertake the orbit maneuver to fly to the L2 point.

This is brilliant management. They not only test return-to-Earth capability, they practice flying a robot ship in deep space, doing complex orbital maneuvers. In addition, depending on the equipment on the service module, they get a cheap unmanned probe for observing the near lunar environment.

Hayabusa-2 scheduled for launch

10:07 am

Delayed due to weather twice, the launch of Japan’s Hayabusa-2 asteroid probe has now been scheduled for Wednesday.

This probe comes with four mini-rovers and an impactor!

Hayabusa 2’s target is a 1km-wide asteroid labelled 1999 JU3, after the year when it was discovered. It is a C-type asteroid, thought to contain more organic material than other asteroids, and so might again help scientists understand how the Solar System evolved.

The Japanese space agency JAXA intend for Hayabusa 2 to catch up with asteroid 1999 JU3 in 2018. It will land a small cube-shaped probe called MASCOT (Mobile Asteroid Surface Scout) developed by the German Space Agency (DLR) together with French space partners the Centre National d’Etudes Spatiales (CNES). The lander is able to move its centre of gravity so that it can tip itself over in order to move across the asteroid’s surface. The three small rovers, called Minerva-II, will also roam the asteroid, gathering data. Hayabusa 2 also carries an impactor that will blast a 2-metre-wide crater in the asteroid’s surface, which will allow the spacecraft to collect fragments and bring them home for study in the laboratory. The spacecraft itself is designed to touch down briefly three times to gather samples.

A scrambled SLS/Orion flight schedule

12:40 am

It ain’t gonna happen: In trying to figure out what to do with SLS/Orion, NASA has admitted that the earliest any crew mission to an asteroid can occur is now 2024.

I could quote from the article, but then I’d have to quote the entire article and comment on the absurdity of practically every sentence. NASA hasn’t the faintest idea what to do with SLS, it isn’t designed to do much of anything, and it doesn’t have the funding to anything even if they knew what they wanted to do with it. Hence, the constant scheduling rearrangements, all designed to push the actual manned flights farther and farther into the future.

The article does point out how NASA is now planning to fly its first crewed mission on SLS/Orion using an untested upper stage, since the rocket costs so much to launch they can’t afford to spend the money on an unmanned test flight beforehand. Meanwhile, they are demanding that SpaceX and Boeing do all kinds of unmanned test flights with their manned capsules at great cost to these companies, before allowing any astronauts on board.

As I’ve said repeatedly, this rocket is never going to fly anyone anywhere. By 2020 several private companies will be sending humans into space regularly at far less cost and with far greater capabilities. Congress will finally realize that they can spread their pork around more effectively by funding these companies instead, and they will cancel this bloated and wasteful program.

Philae’s bouncing, tumbling landing sequence

7:31 am

Scientists and engineers have pieced together the bouncing and tumbling land sequence that Philae went through before it came to rest on Comet 67P/C-G, including the possibility that the second touch down was actually the spacecraft grazing a crater rim.

After the first touchdown, the spin rate started increasing. As the lander bounced off the surface, the control electronics of the flywheel were turned off and during the following 40 minutes of flight, the flywheel transferred its angular momentum to Philae. After this time, the lander was now spinning at a rate of about 1 rotation per 13 seconds;

At 16:20 GMT spacecraft time the lander is thought to have collided with a surface feature, a crater rim, for example. “It was not a touchdown like the first one, because there was no signature of a vertical deceleration due to a slight dipping of our magnetometer boom as measured during the first and also the final touchdown,” says Hans-Ulrich. “We think that Philae probably touched a surface with one leg only – perhaps grazing a crater rim – and after that the lander was tumbling. We did not see a simple rotation about the lander’s z-axis anymore, it was a much more complex motion with a strong signal in the magnetic field measurement.”

Following this event, the main rotation period had decreased slightly to 1 rotation per 24 seconds. At 17:25:26 GMT Philae touched the surface again, initially with just one foot but then all three, giving the characteristic touchdown signal. At 17:31:17 GMT, after travelling probably a few more metres, Philae found its final parking position on three feet.

The search for the spacecraft itself, sitting on the surface, continues.

Safely landing the Falcon 9 first stage on the next launch

8:58 pm

The competition heats up: The website SpaceFlightNow takes a close look at SpaceX’s effort on the next Falcon 9 launch on December 16 to recover the rocket’s first stage.

Musk estimates a 50% chance of success on this launch. Though I think his estimate is reasonable, I also think that this number is a testament to the skill and success of his company. Imagine: in less than three years, since Musk first proposed the idea of landing the first stage vertically, they have come so close to doing it! NASA certainly couldn’t have moved that fast. Neither could most of the experienced launch companies like Arianespace, Boeing, Lockheed Martin, or Russia.

Instead, it takes a new company, a fresh outlook, and freedom to change the world. Who would have guessed?

Proton launch postponed

8:49 pm

The heat of competition: Russian engineers have scrubbed Friday’s commercial Proton launch due to a gyro issue with the rocket’s Briz upper stage.

They have begun to destack the rocket to get at the upper stage in order to repair the problem, with the new launch date expected to be no earlier than mid-December.

The problem once again raises questions about the quality control generally within the Russian aerospace industry and specifically in the companies that build Proton and its upper stage. At the same time, it is a good thing they spotted the problem before launch, allowing them to correct it. That is what a company with good quality control does.

Ralph Vaughan Williams:- A Song of Thanksgiving

6:01 pm

An evening pause: Written for the BBC to mark the end of World War II, Vaughan Williams selected text from the Bible, Shakespeare, and Rudyard Kipling.

Teach us the strength that cannot seek,
By deed, or thought, to hurt the weak;
That, under thee, we may possess
Man’s strength to comfort man’s distress.
Teach us delight in simple things,
The mirth that has no bitter springs;
Forgiveness free of evil done,
And love to all men ‘neath the sun.

Go here for the full lyrics. It is absolutely worthwhile to print them out and read them as you watch this video. The images and words work together with amazing force, and illustrate well the importance of giving thanks on this day.

FAA moves to regulate and thus destroy drone use

1:47 am

We’re here to help you: The FAA is considering a new rule to require a pilot’s license in order to operate a private drone, even drones more akin to model airplanes.

The proposed rules would require that a drone owner would have to get certified as a pilot, “certification that can cost $10,000 and demand many hours flying aircraft that control nothing like a little drone.”

“Knowing the proper flap setting on a short runway approach for a Cessna 172 doesn’t do any good for a DJI Phantom [an inexpensive and popular commercial drone],” said Matt Waite, a University of Nebraska professor and founder of the Drone Journalism Lab. “A lot of people out there already running businesses in conflict with FAA policy, who don’t have pilot licenses, are probably looking at this like, ‘You’ve got to be kidding me.'”

Gee, here we have a new industry that is growing and prosperous, with many people coming up with creative ideas for using drones that none of its inventors ever dreamed of, and the government wants to step in and control it, regulating it to a point where it can’t even exist legally. Isn’t that nice of them?

Court demands documents linked to IRS scandal

12:26 am

Working for the Democratic Party: After years of stonewalling, the Treasury Department has now been ordered by a federal court to release about 2,500 documents connected to the IRS’s illegal release to the Obama administration of the personal tax information of its opponents.

Some time in the next month these documents will become public knowledge. Considering the effort the Obama administration has made to keep them secret, I expect we shall then discover that the IRS was routinely and illegally feeding the Democrats the private tax records of their Republican opponents. Since the documents will also likely name names, we will also find out who among the Democrats demanded this illegal information, who in the IRS gave it to them, and who took that information and used it illegally.

Obamacare and amnesty: working together to screw Americans

11:46 pm

Finding out what’s in it: Because of the way Obamacare is written, it provides employees an incentive to hire illegal immigrants — temporarily and illegally given amnesty by Obama — instead of legal Americans.

Under the president’s new amnesty, businesses will have a $3,000-per-employee incentive to hire illegal immigrants over native-born workers because of a quirk of Obamacare. President Obama’s temporary amnesty, which lasts three years, declares up to 5 million illegal immigrants to be lawfully in the country and eligible for work permits, but it still deems them ineligible for public benefits such as buying insurance on Obamacare’s health exchanges. Under the Affordable Care Act, that means businesses who hire them won’t have to pay a penalty for not providing them health coverage — making them $3,000 more attractive than a similar native-born worker, whom the business by law would have to cover.

Just remember: Obama and the Democrats care! Though what they care about is maybe something more Americans should ask themselves.

Billion-dollar-plus NASA medical research contract under dispute

11:24 pm

A bidding dispute has forced NASA to again put up for bid a $1.5 billion contract for space medicine.

The dispute has to do with two dueling contractors, Wyle and SAIC, both of whom want the big bucks.

After Wyle won the Human Health and Performance contract in March 2013, SAIC filed a protest with the GAO, ultimately prompting NASA to reopen the competition.

When NASA reawarded the contract in August 2013, it chose SAIC. The following month, the McLean, Virginia-based firm — which had announced plans the previous summer to split into two companies — rebranded itself as Leidos and spun off its $4 billion government information technology and technical services unit as a publicly traded firm that kept the name SAIC and was slated to get the Human Health and Performance contract.

But Wyle filed its own protest with GAO in September 2013, arguing that NASA should discount SAIC’s lower bid — at $975 million, nearly 10 percent lower than Wyle’s — because it was submitted when the unit was still part of a much larger company with deeper pockets. This time, the GAO sided with Wyle.

The article says practically nothing about what all this money buys me, the taxpayer. And it is an awful lot of money. Is it for medical research on ISS? Is it for monitoring the health of the astronauts? Is it for biological research? What is it for exactly? I honestly can’t imagine how this kind of research or medical monitoring on ISS can cost this much. My skeptical nature has me wondering if this contract might instead be a bit inflated, much like SLS and Orion, in order to funnel pork to congressional districts to employ as many voters as possible.

First 3D part manufactured in space

11:07 pm

Astronauts on ISS have used a 3D printer, shipped to the station on the last Dragon flight, to print the first item ever manufactured in space.

“Everything worked exactly as planned, maybe a little better than planned,” Kemmer told NBC News. He said only two calibration passes were needed in advance of the first honest-to-goodness print job, which finished up at 4:28 p.m. ET Monday and was pulled out of the box early Tuesday. “It’s not only the first part printed in space, it’s really the first object truly manufactured off planet Earth,” Kemmer said. “Where there was not an object before, we essentially ‘teleported’ an object by sending the bits and having it made on the printer. It’s a big milestone, not only for NASA and Made In Space, but for humanity as a whole.”

The part made was a faceplate for the printer itself. This printer is a demonstration project, launched to test the engineering and to see how 3D printing operates in weightlessness. Eventually the goal is to have most of the spare parts on a interplanetary vehicle manufactured in space in this manner, using a supply of standard material, called feedstock, that would be much cheaper to ship from Earth.

Looking down a comet’s neck

2:09 pm

Looking down Comet 67P/C-G's neck

Because all the focus in past two weeks has been on the attempt to land Philae on the surface of Comet 67P/C-G, no one has been paying much attention to the images that Rosetta has continued to produce. On the right however is a humdinger, released on November 17. The image looks into the neck or saddle of the comet, from the side. The giant boulder Cheops can be seen in the saddle, with a jet visible against the black sky above it.

What I like about this image is that I can imagine hiking up the sandy slope to this narrow saddle, where I could stand next to Cheops and look out at that jet. For the explorer in all of us this sure wets the appetite for the future. If only people could go and do that now!

Italy’s legislature rejects additional funding for space

12:11 am

The Italian legislature has refused to add an additional $250 million to the budget of its space program, money requested to help pay the country’s share in the development of Arianespace’s next generation commercial rocket, Ariane 6.

The money was also needed for several other ESA space projects. Not having it puts a question mark on Italy’s future in space. The article also illustrates how the committee nature of Europe’s cooperative space effort makes it almost impossible for it to compete in the commercial market.
