Robert Salazar has been playing with origami, the Japanese art of paper folding, since he was 8 years old. When he sees a sheet of paper, his imagination takes over and intricate animals take shape.

“Seeing the single uncut sheet, it has everything you need to create all of the origami that have ever been folded. It is all in the single sheet so there is endless potential,” Salazar said.

The endless potential of origami, folding a single sheet of paper into an intricate sculpture, reaches all the way to space.

Salazar’s 17-year experience with origami is appreciated at NASA’s Jet Propulsion Laboratory. As a contractor and intern, Salazar is helping create objects that may one day be used in space exploration.

“Origami offers the potential to take a very large structure, even a vast structure, and you can get it to fit within the rocket, go up, then deploy back out again. So it greatly magnifies what we are capable of building in space,” Salazar said.

Folding a large object into a relatively small space is not a simple task.

“A big challenge in origami design in general is that because all of these folds share a single resource, which is a single sheet … everything is highly interdependent, so if you change just one feature it has an impact on everything else,” Salazar said.

“One of our guide stars really is keep it as simple as can be,” said Manan Arya, a technologist at NASA’s Jet Propulsion Laboratory. “Don’t add unnecessary complexity because every piece of complexity, every piece of hardware you add, that ends up being another potential point of failure.”

Starshade

Folding an object the size of a baseball diamond so that it could fit into a rocket is the goal of a NASA project called Starshade.

Once it opens in space, Starshade would allow a space telescope to better see the planets around bright stars.

“Seeing an exoplanet next to its parent star is like trying to image a firefly next to a search light, the searchlight being the star,” said Arya, who is  working on the Starshade project. “Starshade seeks to block out that starlight so you can image a really faint exoplanet right next to it.”

Origami robot

Origami is also used in designing a robot called the Pop-Up Flat Folding Explorer Robot, or PUFFER. It has a body that can fold itself flat and roll under small spaces. PUFFER has been tested on desert terrains and snowy slopes. It may one day end up on a mission to another planet.

“It [PUFFER] is to explore environments otherwise inaccessible to a robot that could not fold itself to fit inside these cracks, [to] explore cave systems, could be other planets, even on our own,” Salazar said.

Origami antenna

Another application for space origami design is to pack an antenna into satellites the size of a briefcase, called CubeSats.

“The bigger the antenna you have, the more gain your antenna has, so it is useful to have a big antenna that gets packaged into this tiny space that unfolds out to be a large antenna. The biggest CubeSat antennas right now are about half a meter,” Arya said.

Unexplored territory

There are also largely unexplored surfaces that can utilize origami concepts in designing new technologies.

“So often, origami design has been tailored toward materials that are already lying flat,” Salazar said. “But there is actually a vastly, a much larger field of application for which the surfaces are not flat, so they could be parabolic. They could be spherical. They could be many combinations of doubly curved surfaces coming together. All of these things can also be folded.”

In the current origami-inspired technologies being developed at NASA’s Jet Propulsion Laboratory, there is a graceful beauty to the folding and unfolding of designs such as the Starshade, which unfurls into what looks like a sunflower. In origami, Salazar said, art, science and engineering are only superficially different.

“Really, when it comes down to it, you’re looking at the world,” he said. “You’re making observations. You’re finding patterns in these observations. [You’re] developing an understanding of what you see, then using that understanding to create. And when you’re creating, [it] can either be creating with the intention of solving a physical problem or it could be nonphysical. It could be aesthetic. You’re trying to find a particular impact on people when they see your work. So really, the practice is the same.”

In origami, Salazar said art, science and engineering are quite similar. They draw on making observations and creating something that produces an impact.

Paper folding known as origami is widely considered a Japanese art form. From a single piece of paper, an animal, a flower or even a boat can take shape. Besides the fun and artistic side of origami, the art of paper folding also has applications that can take it to outer space.

U.S. President Donald Trump Wednesday ordered the Transportation Department to launch a test program to increase the number of drones for commercial and civil use.

“The program will help tackle the most significant challenges in integrating drones into the national airspace while reducing risks to public safety and security,” the department said.

Under the program, drones will be test flown at night, fly over people for safety tests, fly out of sight of the operators and deliver packages. It would also test technologies to prevent collisions with other aircraft. 

“Drones are proving to be especially valuable in emergency situations, including assessing damage from natural disasters such as the recent hurricanes and the wildfires in California,” Transportation Secretary Elaine Chao said.

A novelty for now

Right now, drones in the United States are largely a novelty. Federal aviation officials say there are about 1 million registered drones in the country. Most of them belong to people who fly them as a hobby.

They are small and relatively inexpensive and can be modified to deliver small packages and even pizzas.

But the lack of federal and local rules and safety regulations have restricted more widespread commercial use.

There is also the inevitable concern that drones could become a tool for terrorists.

Terrorist tool?

FBI Director Christopher Wray recently told a U.S. Senate panel, “The expectation is it’s coming here imminently.” He called drones “relatively easy to acquire, relatively easy to operate, and quite difficult to disrupt and monitor.”

A drone flown by a hobbyist unintentionally crash landed on the White House lawn in 2015.

Along with Wednesday’s announced test program, the Trump administration wants to enhance the powers of police to track drones and shoot down any that appear to be a threat.

Facebook is partnering with a developer to build a wind power farm in northeast Nebraska that will supply energy for the company’s planned data center.

The social media giant announced last week that it has partnered with Trade Winds Energy to build the Rattlesnake Creek Wind Project in rural Dixon County.

Facebook plans to use energy from the wind farm to power its upcoming data center in Papillion, a suburb of Omaha. Of the 320 megawatts of power the wind farm will create, 200 of them will be allocated to the data center while the remaining will be available for other buyers.

Officials said the project will produce the second-largest wind farm in Nebraska, behind the 400-megawatt Grande Prairie project in Holt County. Officials also said the new wind farm will generate enough energy to power 90,000 homes.

Both projects are examples of the state’s rich wind resource being acknowledged, said David Bracht, director of the Nebraska Energy Office.

“The wind projects that have been installed [in Nebraska] have shown themselves to be very, very productive,” Bracht said.

A new electric rate structure rolled out in January by the Omaha Public Power District means Facebook can power its data center with 100 percent clean energy. The company also aims to get at least 50 percent of its total electricity consumption from clean and renewable energy sources in 2018.

Neither Facebook nor Trade Winds provided a timeline or cost for the wind farm.

A university engineering department has developed what amounts to a Tinder app for criminals — a computer program that matches inmates with suitable prisons.

The software, unique in the corrections field, has saved the Pennsylvania Department of Corrections about $3 million in its first year. It’s resulted in fewer prison assaults, shortened wait times for treatment programs by nearly two months, reduced the number of prison transfers and lightened the workload of corrections staff.

Corrections officials marvel that nobody thought of it sooner.

“It’s pretty amazing, and what we’ve seen so far is the outcomes are a lot better,” said Major William Nicklow of the state prison in Camp Hill, who oversaw the project as the prison system’s director of population management.

On Tuesday, the Lehigh University team that developed the software accepted the Wagner Prize, the top international prize in the field of operations research practice.

Their work has dramatically simplified the job of assigning inmates to prisons.

Previously, corrections staff handled prisoner assignments one at a time, a laborious and inefficient process that meant inmates farther down the list were at a disadvantage when it came to placement in high-demand treatment programs.

The software, in contrast, can assign hundreds of inmates simultaneously, taking into account dozens of factors including age and other inmate demographics, criminal history, mental illness, and educational and vocational interests to come up with the most appropriate placement for each inmate. It also identifies gang members as well as inmates most likely to be violent and separates them, reducing the threat at individual prisons.

The software can finish in minutes what it took a staff of seven an entire week to do.

“This very complex problem is mathematically modeled, put in the system and the system is advising where the inmate has to be assigned,” said Tamas Terlaky, one of the program’s developers and a professor in Lehigh’s industrial and systems engineering department. “The benefits are quite obvious.”

Other corrections departments have taken note. At least three other states as well as the federal prison system have made inquiries about the software, Terlaky said.

Americans could see a lot more drones flying around their communities as the result of a Trump administration test program to increase government and commercial use of the unmanned aircraft.

President Donald Trump gave the go-ahead Wednesday, signing a directive intended to increase the number and complexity of drone flights.

The presidential memo would allow exemptions from current safety rules so communities could move ahead with testing of drone operations.

States, communities and tribes selected to participate would devise their own trial programs in partnership with government and industry drone users. The administration anticipates approving at least five applications, but there is no limit on the number of communities that can join.

The Federal Aviation Administration would review each program. The agency would grant waivers, if necessary, to rules that now restrict drone operations. Examples include prohibitions on flights over people, nighttime flights and flights beyond the line of sight of the drone operator.

Among the things that could be tested are package deliveries; the reliability and security of data links between pilot and aircraft; and technology to prevent collisions between drones and other aircraft and to detect and counter drones flying in restricted areas.

Drone-makers and businesses that want to fly drones have pushed for looser restrictions. Trump discussed the issue with industry leaders at a White House meeting in June.

In the past two years, the FAA has registered over 1 million drones. The majority of them belong to hobbyists. There are now more registered drones than registered manned aircraft in the U.S.

Safety restrictions on drone flights have limited drone use, and U.S. technology companies seeking to test and deploy commercial drones have often done so overseas. For example, Google’s Project Wing is testing drones in Australia, and Amazon is testing drone deliveries in the United Kingdom.

“In order to maintain American leadership in this emerging industry here at home, our country needs a regulatory framework that encourages innovation while ensuring airspace safety,” Michael Kratsios of the White House Office of Science and Technology Policy told reporters in a conference call.

The trial program will collect data on drone operations that will aid the government’s effort to develop a separate air traffic control system for low-flying unmanned aircraft, he said.

The test zones are expected to start going into place in about a year. The program would continue for three years after that.

Safety concerns over drones have risen recently after the collision of a civilian drone and an Army helicopter over Staten Island, New York, and the first verified collision in North America between a drone and a commercial aircraft, in Quebec City, Canada.

The test program doesn’t address complaints by local governments that low-flying drones present safety, privacy and nuisance risks. The FAA says it has the sole authority to regulate the national airspace, but some communities have passed their own restrictions.

Doug Johnson, vice president of technology policy at the Consumer Technology Association, said the test program recognizes that “the federal government cannot manage policymaking and enforcement by itself” and must work with local governments.

“Public-private partnerships like those that would be created by the program are critical to realizing the economic benefits of drones,” he said.

The association, whose members include drone-makers, has estimated 3.4 million drones valued will be sold in the U.S. this year, 40 percent more than last year. Revenue from those sales is estimated at about $1.1 billion.

A new strain of malicious software has paralyzed computers at a Ukrainian airport, the Ukrainian capital’s subway and at some independent Russian media.

The Odessa international airport in Ukraine’s south, the Kyiv subway and prominent Russian media outlets such as Interfax and Fontanka on Tuesday reported being targeted.

The cyberattack appears to be similar to a major attack in June that locked the computers of hospitals, government offices and major multinationals with encryption that demanded a ransom for their release. The software appeared to have originated in Ukraine.

Moscow-based cyber security firm Group-IP said in a statement Wednesday the ransomware called BadRabbit also tried to penetrate the computers of major Russian banks but failed. None of the banks has reported any attacks.

Moscow-based cyber security company Kaspersky Lab said it was aware of more than 200 companies in Russia, Ukraine, Turkey and Germany targeted by the ransomware.

The Odessa airport said in a statement its information systems have been affected, although it continues to service flights. The subway in the capital, Kyiv, said it cannot process online payments and bank card payments.

The operations of Russia’s only privately owned news agency, Interfax, have been paralyzed since Tuesday.

 
…

Sometime in 2014, a group of analysts walked into the office of Eugene Kaspersky, the ebullient founder of Russian cybersecurity firm Kaspersky Lab, to deliver some sobering news. The analysts were in possession of a cache of files belonging to the Equation Group, an extraordinarily powerful band of hackers that would later be exposed as an arm of the U.S. National Security Agency. But the analysts were worried; the files were classified.

“They immediately came to my office,” Kaspersky recalled, “and they told me that they have a problem.”

According to him, there was no hesitation about what to do with the cache.

“It must be deleted,” Kaspersky says he told them.

The incident, recounted by Kaspersky during a brief telephone interview on Monday and supplemented by a preliminary timeline provided by company officials, could not be immediately corroborated. But it’s the first public acknowledgement of a story that has been building for the past three weeks — that Kaspersky’s popular anti-virus program uploaded powerful digital espionage tools belonging to the NSA and sent them to servers in Moscow.

The account provides new perspective on the U.S. government’s recent move to blacklist Kaspersky from federal computer networks, even if it still leaves important questions unanswered.

To hear Kaspersky tell it, the incident was an accident borne of carelessness.

Kaspersky was already on the trail of the Equation Group when one of its customers in the United States — Kaspersky referred to them as a “malware developer” — ran at least two anti-virus scans on their home computer after it was infected by a pirated copy of Microsoft Office 2013, according to Kaspersky’s timeline. That triggered an alert for Equation Group files hidden in a compressed archive which was spirited to Moscow for analysis.

Kaspersky’s story at least partially matches accounts published in The New York Times, The Washington Post and The Wall Street Journal. All three publications recently reported that someone at the NSA’s elite hacking unit lost control of some of the agency’s powerful surveillance tools after they brought their work home with them, leaving what should have been closely guarded code on a personal computer running Kaspersky’s anti-virus software.

But information security experts reading the bits of information dropped by anonymous government officials are still puzzling at whether Kaspersky is suspected of deliberately hunting for confidential data or was merely doing its job by sniffing out suspicious files.

Much of the ambiguity is down to the nature of modern anti-virus software, which routinely submits rogue files back to company servers for analysis. The software can easily be quietly tweaked to scoop up other files too: perhaps classified documents belonging to a foreign rival’s government, for example.

Concerns have been fanned by increasingly explicit warnings from U.S. government officials after tensions with Russia escalated in the wake of the 2016 presidential election.

Kaspersky denied any inappropriate link to the Russian government, and said in his interview that any classified documents inadvertently swept up by his software would be destroyed on discovery.

“If we see confidential or classified information, it will be immediately deleted and that was exactly [what happened in] this case,” he said, adding that the order had since been written into company policy.

An AP request for a copy of that policy wasn’t immediately granted.

Kaspersky’s account still has some gaps. How did the analysts know, for example, that the data was classified? And why not alert American authorities to what happened? Several reports alleged that the U.S. learned that Kaspersky had acquired the NSA’s tools via an Israeli spying operation.

Kaspersky declined to say whether he had ever alerted U.S. authorities to the incident.

“Do you really think that I want to see in the news that I tried to contact the NSA to report this case?” he said at one point. “Definitely I don’t want to see that in the news.”

So did he alert the NSA to the incident or not?

“I’m afraid I can’t answer the question,” he said.

Even if some questions linger, Kaspersky’s explanation sounds plausible, said Jake Williams, a former NSA analyst and the founder of Augusta, Georgia-based Rendition InfoSec. He noted that Kaspersky was pitching itself at the time to government clients in the United States and may not have wanted the risk of having classified documents on its network.

“It makes sense that they pulled those up and looked at the classification marking and then deleted them,” said Williams. “I can see where it’s so toxic you may not want it on your systems.”

As for the insinuation that someone at the NSA not only walked highly classified software out of the building but put it on a computer running a bootleg version of Office, Williams called it “absolutely wild.”

“It’s hard to imagine a worse PR nightmare for the NSA,” he said.

Facebook Inc said on Monday it was testing the idea of dividing its News F eed in two, separating commercial posts from personal news in a move that could lead some businesses to increase advertising.

The Facebook News Feed, the centerpiece of the world’s largest social network service, is a streaming series of posts such as photos from friends, updates from family members, advertisements and material from celebrities or other pages that a user has liked.

The test, which is occurring in six smaller countries, now  offers two user feeds, according to a statement from the company: one feed focused on friends and family and a second dedicated to the pages that the customer has liked.

The change could force those who run pages, everyone from news outlets to musicians to sports teams, to pay to run advertisements if they want to be seen in the feed that is for friends and family.

The test is taking place in Bolivia, Cambodia, Guatemala, Serbia, Slovakia and Sri Lanka, and it will likely go on for months, Adam Mosseri, the Facebook executive in charge of the News Feed, said in a blog post.

Mosseri said the company has no plans for a global test of the two separate feeds for its 2 billion users.

Facebook also does not currently plan to force commercial pages “to pay for all their distribution,” he said.

Facebook, based in Menlo Park, California, frequently tests changes big and small as it tries to maximize the time people spend scrolling and browsing the network. Sometimes it makes changes permanent, and other times not.

Depending on how people respond, two news feeds could mean that they see fewer links to news stories. News has proved to be a tricky area for Facebook, as hoaxes and false news stories have sometimes spread easily on the network.

The test has already affected website traffic for smaller media outlets in recent days, Slovakian journalist Filip Struharik wrote over the weekend in a post on Medium.

Publishers might need to buy more Facebook ads to be seen, he wrote: “If you want your Facebook page posts to be seen in old newsfeed, you have to pay.”

Amazon said Monday that it received 238 proposals from cities and regions in the United States, Canada and Mexico hoping to be the home of the company’s second headquarters.

The online retailer kicked off its hunt for a second home base in September, promising to bring 50,000 new jobs and spend more than $5 billion on construction. Proposals were due last week, and Amazon made clear that tax breaks and grants would be a big deciding factor on where it chooses to land.

Amazon.com Inc. said the proposals came from 43 U.S. states as well as Washington, D.C., and Puerto Rico, three Mexican states and six Canadian provinces. In a tweet, the company said it was “excited to review each of them.”

Besides looking for financial incentives, Amazon had stipulated that it was seeking to be near a metropolitan area with more than a million people; be able to attract top technical talent; be within 45 minutes of an international airport; have direct access to mass transit; and be able to expand that headquarters to as much as 8 million square feet in the next decade.

Generous tax breaks and other incentives can erode a city’s tax base. For the winner, it could be worth it, since an Amazon headquarters could draw other tech businesses and their well-educated, highly paid employees.

The seven U.S. states that Amazon said did not apply were: Arkansas, Hawaii, Montana, North Dakota, South Dakota, Vermont and Wyoming.

Ahead of the deadline, some cities turned to stunts to try and stand out: Representatives from Tucson, Arizona, sent a 21-foot tall cactus to Amazon’s Seattle headquarters; New York lit the Empire State Building orange to match Amazon’s smile logo.

The company plans to remain in its sprawling Seattle headquarters, and the second one will be “a full equal” to it, founder and CEO Jeff Bezos said in September. Amazon has said that it will announce a decision sometime next year.
