Facebook now identifies potential suicides for authorities to take action

December 1, 2017 2:56 pm Robert Zimmerman

Reason #3,434,389 why I don’t use Facebook: Facebook has developed software that identifies what it thinks are suicidal thoughts by a user, then sends that information to the government so it can take immediate action.

The social network has been testing the tool for months in the US, but is now rolling out the program to other countries. The tool won’t be active in any European Union nations, where data protection laws prevent companies from profiling users in this way.

In a Facebook post, company CEO Mark Zuckerberg said he hoped the tool would remind people that AI is “helping save peoples’ lives today.” He added that in the last month alone, the software had helped Facebook flag cases to first responders more than 100 times. “If we can use AI to help people be there for their family and friends, that’s an important and positive step forward,” wrote Zuckerberg. “The AI looks for comments like “are you ok?” and “can I help?””

Despite this emphasis on the power of AI, Facebook isn’t providing many details on how the tool actually judges who is in danger.

The potential for abuse here is beyond words. Worse, Facebook’s unwillingness to be transparent about this software makes it even more suspect. From the article:

TechCrunch writer Josh Constine noted that he’d asked Facebook how the company would prevent the misuse of this AI system and was given no response.

As I’ve written previously, companies like Google, Facebook, and Microsoft might be providing their customers some good products, but they are also doing so from a very amoral position, abusing the privacy of their customers in ways that are simply wrong. While this software is likely being used today in a totally correct way, I have strong doubts about it in the long term. As the politics of our time become even more heated, partisan, and childish, the temptation to use this software to target and eliminate those who disagree with either Facebook or its allies in the government will certainly grow. And then, how does one protect oneself from this abuse?

Baby stars at center of galaxy

December 1, 2017 2:40 pm Robert Zimmerman

New observations of the region surrounding Sagittarius A* (Sgr A*), the super-massive black hole at the center of the Milky Way, has confirmed earlier research by finding what appears to be eleven newly formed baby stars.

Prior observations of the region surrounding Sgr A* by Zadeh and his team had revealed multiple massive infant stars but the finding was not conclusive. These objects, known as proplyds, are common features in more placid star-forming regions, like the Orion Nebula. The new measurements provide more conclusive evidence for young star formation activity. Though the galactic center is a challenging environment for star formation, it is possible for particularly dense cores of hydrogen gas to cross the necessary threshold and forge new stars.

The new ALMA observations, however, revealed something even more remarkable, signs that 11 low-mass protostars are forming within one parsec – a scant three light-years – of the galaxy’s central black hole. Zadeh and his team used ALMA to confirm that the masses and momentum transfer rates – the ability of the protostar jets to plow through surrounding interstellar material – are consistent with young protostars found throughout the disk of our galaxy. “This discovery provides evidence that star formation is taking place within clouds surprisingly close to Sagittarius A*,” said Al Wootten with the National Radio Astronomy Observatory in Charlottesville, Virginia, and co-author on the paper.

They have several theories on how new stars could coalesce in such a violent and turbulent region, but none appears that convincing. Essentially, this is a mystery that does not yet have an answer. It does tell us however that star formation can occur almost anywhere.

The organic dust of Comet 67P/C-G

December 1, 2017 11:36 am Robert Zimmerman

A study of the dust released by Comet 67P/C-G and captured by Rosetta shows that carbon molecules appear to comprise the comet’s largest component, and that this material is found in the form of very large macromolecules.

As the study shows, organic molecules are among those ingredients at the top of the list. These account for about 45 percent of the weight of the solid cometary material. “Rosetta’s comet thus belongs to the most carbon-rich bodies we know in the solar system,” says MPS scientist and COSIMA team member Dr. Oliver Stenzel. The other part of the total weight, about 55 percent, is provided by mineral substances, mainly silicates. It is striking that they are almost exclusively non-hydrated minerals i.e. missing water compounds. “Of course, Rosetta’s comet contains water like any other comet, too,” says Hilchenbach. “But because comets have spent most of their time at the icy rim of the solar system, it has almost always been frozen and could not react with the minerals.” The researchers therefore regard the lack of hydrated minerals in the comet’s dust as an indication that 67P contains very pristine material.

…The current findings also touch on our ideas of how life on Earth came about. In a previous publication, the COSIMA team was able to show that the carbon found in Rosetta’s comet is mainly in the form of large, organic macromolecules. Together with the current study, it becomes clear that these compounds make up a large part of the cometary material. Thus, if comets indeed supplied the early Earth with organic matter, as many researchers assume, it would probably have been mainly in the form of such macromolecules.

Organic here does not mean life, but is instead used as chemists use it, to mean the molecule includes the element carbon. The results do suggest however that the early solar system had a lot of carbon available, and that much of it was in a relatively pure form available to interact with other elements.

Watch a rocket tank being built, mostly by robots

December 1, 2017 10:39 am Robert Zimmerman

Capitalism in space: The video below the fold shows the process by which Interorbital Systems built a rocket test tank for the Neptune smallsat rocket it is developing. It is definitely worth watching if you want to see the future of complex manufacturing. Robotic equipment does most of the work, in a precise manner that would be impossible for humans, which therefore allows for the construction of engineering designs that were previously impossible or too expensive. Now, such designs can be built relatively cheaply, and repetitively.

Development at SpaceX’s Texas spaceport to pick up in 2018

December 1, 2017 10:31 am Robert Zimmerman

Capitalism in space: Though construction at SpaceX’s Texas spaceport has been slower than expected, the company expects to accelerate development in 2018.

According to SpaceX, [people] won’t have to wait much longer for an increase in activity at the future spaceport. The recently installed antennas at Boca Chica are expected to be operational next year — although they’ll initially track flights blasting off from elsewhere — and the company also indicated development of the overall launch complex should pick up. “Even as our teams worked to modernize and repair our launch complexes in Florida so that we could reliably return to flight for our customers, SpaceX invested $14 million into the South Texas project,” said Gleeson, the company’s spokesman.

“Now, with our launch construction projects in Florida wrapping up by early 2018, SpaceX will be able to turn more attention to our work in South Texas,” he said.

In other words, once SpaceX has got its two launchpads in Florida both up and running, including the first use by the Falcon Heavy of one of those pads, the company will then be able to shift its launchpad operations down to Texas.

The article outlines in detail many of the reasons the development has been slow, but I think the issues highlighted in the quote above, issues I had not considered previously, might be the most important. After the September 2016 launchpad explosion in Florida, SpaceX had to divert resources to repairing that pad, which put Boca Chica on the back burner.

Moon Express will launch to Moon in 2018, regardless of X-Prize deadline

December 1, 2017 10:23 am Robert Zimmerman

Capitalism in space: The head of Moon Express said yesterday that the company will definitely fly its privately-built lunar rover to the Moon in 2018, regardless of whether that flight occurs in time to win the Google Lunar X-Prize.

The company is competing for the Google Lunar XPRIZE which has a $20 million reward for the first private firm to put a spacecraft on the moon, travel 500 meters, and transmit high definition video and images back to earth. The deadline for doing this is March 2018.

Jain did not give an exact date for the launch and said that getting the prize isn’t necessarily the main priority.

It appears to me that the main reason they will not make the deadline is because Rocket Lab’s Electron rocket won’t be ready in time. This is why its second test launch in the coming weeks is so important. If successful, it increases the chances that Moon Express will be able to meet the X-Prize deadline.

Europe commits $107 million for new rocket and space plane

November 30, 2017 8:56 pm Robert Zimmerman

The European Space Agency (ESA) today allocated $107 million to develop both a new larger version of its Vega rocket as well as an orbital version of the spaceplane engineering test vehicle flown in 2015.

The Vega-E will be larger and will give them another rocket capable of competing for launch business, but the space plane project is more interesting.

ESA awarded 36.7 million split between Avio and Thales Alenia Space Italy for Space Rider, an unmanned spaceplane capable of lifting 800 kilograms to LEO for missions up to two months. A single Space Rider should be capable of six missions with refurbishing, according to Thales Alenia Space.

Space Rider leverages technology from ESA’s Intermediate Experimental Vehicle (IXV), which performed a suborbital mission in February 2015, landing in the Pacific Ocean. Unlike its predecessor, Space Rider is designed for ground landings. ESA tasked Thales Alenia Space with building Space Rider’s reentry module based on the IXV.

It seems Europe wants its own version of X-37B and Dream Chaser.

House panel approves concealed carry reciprocity for all 50 states

November 30, 2017 12:53 pm Robert Zimmerman

The House Judiciary committee yesterday approved a nationwide law that would require states to recognize the legality of concealed carry licenses from other states.

The legislation allows firearm owners with a concealed carry permit issued by their home state to carry the firearm into any other state (all allow some form of concealed carry, although many are highly restrictive). The gun owners wouldn’t have to reveal they are carrying a weapon, though the bill does require they be eligible to possess a firearm under federal law (which requires a background check), carry a valid photo identification and a concealed carry permit. Gun owners from states that don’t require a concealed carry permit will need to obtain some credential from their home state to take advantage of the new law’s provisions. What form that would take isn’t specified in the House bill.

The bill still has to pass both the House and the Senate. A similar bill in the Senate already has 38 co-sponsors.

The article is typical for the modern mainstream press. It spends a lot of time getting quotes from numerous anti-gun groups and Democratic politicians, but never highlights the numerous examples in recent years where entirely innocent individuals have had their lives ruined because they entered places like New Jersey, DC, and New York with a gun that was totally legal in their home states.

More delays in Democratic IT scandal

November 30, 2017 10:52 am Robert Zimmerman

The attorney for Imran Awan, the computer specialist who had worked for numerous Democratic congressmen, including Debbie Wasserman Schlutz and is now charged with bank fraud, has caused a month delay in the court case in an effort to block the use of a laptop and its contents as evidence.

Wasserman Schultz fought to prevent law enforcement from looking at the laptop, threatening a police chief with “consequences” and implying it was “a member’s” laptop. She hired an outside lawyer, Bill Pittard, who specializes in the “speech and debate” clause of the Constitution that is designed to protect lawmakers from persecution for political stances, but lawmakers have used to try to stymie criminal probes in the past.

Now, it is Awans’ lawyers who are seeking the right to keep information in the backpack, including the “hard drive,” from being used as evidence.

The Awan attorneys are claiming that the laptop and all other information found in the backpack should be blocked as evidence because they fall under attorney-client privilege. This is absurd. If the court agrees with this interpretation, it will allow criminals to declare almost all evidence inadmissible, just by claiming it was communications between lawyer and client.

Based on all this effort to keep law enforcement from seeing what’s on that laptop, I suspect it contains some very damning information, both to Awan as well as to Wasserman Schultz and many other Democrats who had hired Awan.

Someone in India finally reads its proposed oppressive space law

November 30, 2017 9:25 am Robert Zimmerman

Link here. The analysis of India’s proposed new space law [pdf] is generally very negative, but strangely it avoids entirely the bill’s worst aspect, its requirement that everything launched by India into space must belong to the government.

Instead, the author focuses on how the bill’s broad language fails to deal with specific issues of insurance, the licensing of different kinds of space activities, and environmental pollution. In other words, it appears he cannot see the forest because of the trees.

In the end, however, in concluding that the bill as written does not serve the private sector he does make one good suggestion that I hope the Indian government takes to heart.

It will not do justice to the entrepreneurial community if this Bill is implemented as is. One of the exercises that can be conducted to align the Bill to enable a competitive ecosystem for commercial space in India is to conduct a review of international best practices in managing the space value chain and inducting them within the Bill.

In other words, read what other nations like the U.S. and Luxembourg are doing to encourage their private commercial space sector. India might find that the last entity allowed to own something in space should be the government.

Chinese space probe detects possible dark matter signal

November 30, 2017 8:56 am Robert Zimmerman

The uncertainty of science: A Chinese space probe designed to measure cosmic rays has detected a pattern that could be evidence of the existence of dark matter.

Researchers launched the spacecraft from the Jiuquan Satellite Launch Center in the Gobi Desert, about 1600 kilometers west of Beijing, in December 2015. Its primary instrument—a stack of thin, crisscrossed detector strips—is tuned to observe the incoming direction, energy, and electric charge of the particles that make up cosmic rays, particularly electrons and positrons, the antimatter counterparts of electrons. Cosmic rays emanate from conventional astrophysical objects, like exploding supernovae in the galaxy. But if dark matter consists of WIMPs, these would occasionally annihilate each other and create electron-positron pairs, which might be detected as an excess over the expected abundance of particles from conventional objects.

In its first 530 days of scientific observations, DAMPE detected 1.5 million cosmic ray electrons and positrons above a certain energy threshold. When researchers plot of the number of particles against their energy, they’d expect to see a smooth curve. But previous experiments have hinted at an anomalous break in the curve. Now, DAMPE has confirmed that deviation. “It may be evidence of dark matter,” but the break in the curve “may be from some other cosmic ray source,” says astrophysicist Chang Jin, who leads the collaboration at the Chinese Academy of Science’s (CAS’s) Purple Mountain Observatory (PMO) in Nanjing. [emphasis mine]

I must emphasize the large uncertainty here. They have not detected dark matter. Not even close. What they have detected is a pattern in how the spacecraft is detecting cosmic rays that was predicted by the existence of dark matter. That pattern however could have other causes, and the consistent failure of other efforts to directly find dark matter strengthens the possibility that this break is caused by those other causes.

Soyuz failed because it was programmed for Baikonur, not Vostochny

November 30, 2017 8:39 am Robert Zimmerman

It now appears that the Soyuz rocket failure this week occurred because the Fregat upper stage had not been programmed for a launch from Vostochny.

Although the information is still preliminary, it is increasingly clear that all the hardware aboard the Fregat upper stage performed as planned. But, almost unbelievably, the flight control system on the Fregat did not have the correct settings for the mission originating from the new launch site in Vostochny, as apposed to routine launches from Baikonur and Plesetsk. As a result, as soon as Fregat and its cargo separated from the third stage of the launch vehicle, its flight control system began commanding a change of orientation of the stack to compensate for what the computer had perceived as a deviation from the correct attitude, which was considerable. As a result, when the Fregat began its first preprogrammed main engine firing, the vehicle was apparently still changing its attitude, which led to a maneuvering in a wrong direction. [emphasis mine]

This reminds me of the NASA’s epic failure with Mars Climate Orbiter in 1998, where some programming used the metric system and other programming used the English system, and no one noticed.

Review of all Soyuz upper stages ordered by Russian manufacturer

November 29, 2017 6:44 pm Robert Zimmerman

According to anonymous sources, the Russian manufacturer of the Freget upper stage that failed yesterday during a Soyuz commercial launch has ordered a review of all Fregets.

The Lavochkin research and production association will check all manufactured Fregat boosters, a source in the space industry told TASS on Wednesday after a recent failed launch. “The Lavochkin Research and Production Association will check all Fregat boosters produced earlier. If defects are found, they [the boosters] will be sent for further development,” the source said.

The Lavochkin Research and Production Association did not comment on this information for TASS.

The problem is that Russia already spent almost a full year beginning in early 2016 checking all its rocket engines for substandard construction done by a corrupt manufacturer. Even though the Fregat is built by another manufacturer, did they not check the Fregat upper stages then also?

NASA confirms next Dragon launch will be on used first stage

November 29, 2017 6:32 pm Robert Zimmerman

Capitalism in space: NASA today confirmed that it has finally approved the use of a Falcon 9 used first stage for the next Dragon launch on December 8.

NASA had said back on November 12 that they were considering this idea. It seems to me that SpaceX has probably been proceeding under the assumption they would say yes, which essentially at this point, only a few weeks from launch, put pressure on the timid NASA bureaucracy to finally get on the bandwagon.

India’s next launch might slip to 2018

November 29, 2017 9:22 am Robert Zimmerman

India’s next PSLV commercial launch might slip to 2018, despite months of effort to resume launches in 2017 following the August 31 PSLV launch failure when the rockets fairing did not release.

“We are working towards it. It will be in the end of December or first week of January. In that time frame,” ISRO Chairman A S Kiran Kumar said.

Kumar also said ISRO will try to launch on an average of once a month in 2018. The article also mentions the new and very oppressive Indian space law that has been proposed.

Asked whether the Space Activities Bill, 2017 would come up during the Budget session of Parliament, Kiran Kumar said “We have now put it in public comments. It would have to go through a set of discussions. The process has started.”

The draft of the proposed Bill to promote and regulate space activities of India, along with encouraging the participation of the private sector, has been uploaded on the ISRO website for comments from stakeholders and the public. [emphasis mine]

The highlighted text is typical of all news reports coming from India. The law does no such thing, and in fact will strongly discourage any work by the private sector. It appears that in India reporters either do not read the text of laws they are reporting on, or they really do not have freedom of the press there.

“Yeti” DNA found to come from bears and dogs

November 29, 2017 8:59 am Robert Zimmerman

Scientists analyzing DNA samples said to come from either the legendary yeti in the Himalayas or sasquatch in North America have found that all come from known ordinary animals, mostly bears.

Of the nine “yeti” samples, eight turned out to be from bears native to the area, the researchers report today in the Proceedings of the Royal Society B. The other sample came from a dog. Similar studies of hair samples supposedly related to North America’s big hairy hominid, the sasquatch (aka Bigfoot), have revealed that those fibers came from bears, horses, dogs, and a variety of other creatures—even a human.

Debunking aside, the new study also yielded lots of scientifically useful info, Lindqvist says. The analyses generated the first full mitochondrial genomes for the Himalayan brown bear (Ursus arctos isabellinus) and the Himalayan black bear (Ursus thibetanus laniger), for example. That could help scientists figure out how genetically different these rare subspecies are from more common species, as well as the last time these groups shared maternal ancestors in the past.

While we must always recognize the uncertainties of science, we must also recognize when it provides us clarity. This is an example of the latter.

Wind eating away the Martian terrain

November 28, 2017 9:44 am Robert Zimmerman

Yardangs on Mars

Cool image time! The Mars Reconnaissance Orbiter (MRO) image on the right, cropped and reduced in resolution to post here, shows the transition zone between the lower flat plain to the north and the higher but rougher region to the south. What makes it interesting is the north-south aligned mesas. These are yardangs, a geological feature that actually acts like a weather vane.

Yardangs are composed of sand grains that have clumped together and have become more resistant to erosion than their surrounding materials.

As the winds of Mars blow and erode away at the landscape, the more cohesive rock is left behind as a standing feature. (This Context Camera image shows several examples of yardangs that overlie the darker iron-rich material that makes up the lava plains in the southern portion of Elysium Planitia.) Resistant as they may be, the yardangs are not permanent, and will eventually be eroded away by the persistence of the Martian winds.

For scientists observing the Red Planet, yardangs serve as a useful indicator of regional prevailing wind direction. The sandy structures are slowly eroded down and carved into elongated shapes that point in the downwind direction, like giant weathervanes. In this instance, the yardangs are all aligned, pointing towards north-northwest. This shows that the winds in this area generally gust in that direction.

Crater splash

The wind comes from the southeast and blows to the northwest, and is slowly wearing down the southern rougher terrain. Why some of these yardangs are surrounded by dark material remains a mystery, as noted I noted in a previous post.

Meanwhile, the northern plain is not as boring as it seems. Only a short distance to the north is an unusual crater, cropped from the full image to show here on the right. To my eye, when this impact occurred it literally caused a splashlike feature of compressed and more resistant material. Over time, the prevailing wind has eroded away the surrounding less resistant regolith to better reveal that splash, leaving behind a mesa with a crater in its center.

Why the impact created this splash tells us something about the density and make-up of the plain. It suggests to me a surface that was once muddy and soft that over time has hardened like sandstone.

Worms on Mars!

November 28, 2017 9:09 am Robert Zimmerman

Scientists growing plants on Earth using a simulated Martian soil have found that earthworms like it.

These slimy invertebrates play a key role in making Earth soil healthy by digesting dead organic matter and excreting a potent fertilizer that helps release nutrients like nitrogen and phosphorus. Their constant burrowing also helps lighten up the soil, allowing air and water to seep through better.

That’s an important improvement for the simulated Mars soil, which water struggled to soak through in previous tests. Altogether, the tests showed that the combination of worms and pig slurry helped the plants grow in Martin soil, and the worms not only thrived but reproduced. “Clearly the manure stimulated growth, especially in the Mars soil simulant, and we saw that the worms were active,” says Wamelink. “However, the best surprise came at the end of the experiment when we found two young worms in the Mars soil simulant.”

Obviously, we do not know yet how the worms would respond to the lower Martian gravity, but it sure would be a significant experiment to see them reproduce there.

SpaceX raises another $100 million in investment capital

November 28, 2017 9:03 am Robert Zimmerman

Capitalism in space: In its current round of stock sales SpaceX had raised another $100 million in investment capital.

In August, the space exploration company sold $349.9 million worth of shares, a Securities and Exchange Commission (SEC) filing showed. That amount has now risen to $449.9 million, a new filing showed on Monday, adding an extra $100 million onto the current fundraising effort.

The latest injection of cash values SpaceX at $21.5 billion, according to Equidate, a platform that facilitates the trading of shares in private technology firms. SpaceX was not immediately available for comment on the valuation when contacted by CNBC.

If I was a big money investor I too would be interested in buying some SpaceX stock. Meanwhile, Aviation Week is reporting that the first Falcon Heavy launch has slipped to 2018. I am not surprised, but I have also not seen any other news reports on this, so I am withholding judgement.

Second Soyuz launch from Vostochny a failure

November 28, 2017 8:50 am Robert Zimmerman

The second Soyuz rocket launch from Russia’s new spaceport in Vostochny ended in failure this morning due to a problem with the rocket’s upper stage

It is presently unclear what happened. One Russian news report suggests “human error,” though I do not understand exactly what they mean by that. Either way, all 19 satellites, including a new Russian weather satellite and 18 smallsats, were lost.

For Russia, this failure comes at a bad time. Roscosmos had been striving to recover from last year’s recall of all rocket engines due to corruption at one of their factories. A new launch failure, especially if it is due to another engine issue, will not encourage sales from the international market. Worse, the lose of the 18 smallsats on this launch will certainly make future smallsat companies more reluctant to fly on a Russian rocket.
