The Future of Space Travel: Stamp-Sized Thrusters

MIT_microthrustersReducing the cost of space missions is one of the greatest challenges facing engineers and technicians today. With a myriad of planned missions, ranging from everything to a settlement on the Moon, sending satellites to Near-Earth asteroids, and manned missions to Mars, the goal of making space travel more affordable is a persistent and important one.

As it stands, most efforts are directed towards created craft that are either reusable, repurposed, or simply don’t rely on big, expensive and disposable rockets to get them into orbit. But another angle at bringing the cost of missions down is focusing on the size of the space craft themselves. If they could be shrunk down to the point where they are no larger than a paperweight, sending them into space could be done on the cheap.

cubesatAlready we are seeing this idea at work with CubeSats, a new breed of satellites that are roughly the size of a Rubik’s cube. Over the past decade, dozens of these satellites have been sent into space, often as part of University projects. Since most sensor and survey equipment is now small enough that it can fit into a shoebox, the CubeSat design is ideal for departments that cannot afford to mount multimillion dollar space missions.

Expanding on this concept, MIT’s Poalo Lozano, a professor and the director of the Institute’s Space Propulsion Laboratory, has unveiled a new type of “microthruster” which, when added to the scaled-down satellites, could radically reduce the cost of space missions even further.  Roughly the size of a stamp, these tiny ion-engines would prolong the use of satellites by ensuring they could maneuver in space.

CubeSatsUp until now, CubeSat’s have had a limited life expectancy as their orbits inevitably decay and they burn up in the Earth’s atmosphere. But by equipping them with an Electrospray Propulsion System (iEPS), these pint-sized satellites would be able to conduct life-saving maneuvers that would extend their period of service and give them new functionality.

The thrusters are basically a liquid-fuel system that, when a voltage is applied, emit a stream of ions through tiny nozzles that propel the satellite forward. According to Lozano, four of these thrusters could provide attitude control and main propulsion for standard solar-powered “1U” CubeSat, which measures about 10 centimeters (4 inches) on a side and weighs 1 kilogram (2.2 pounds).

europa-lander-2But more exciting are the long-term prospects created by the addition of these tiny thrusters. For the price of sending a large spacecraft, a fleet of CubeSats could be dispatched to explore the moons of Jupiter. Other possible missions include clearing the massive pile of orbital debris floating around the Earth, de-orbiting satellites at the end of their service lives, and correcting atmospheric drag in low Earth orbit.

Part of what makes plans like these so feasible is the fuel-to-weight ratio it allows for spacecraft, something which astronauts and space agencies always have to take into account. As the Space Propulsion Laboratory claims on their website:

Less than 150 g of propellant would be required by a 1U CubeSat to reach Earth’s escape velocity from [low Earth orbit] and explore interplanetary space.

cubesats2Other possibilities arise from the fact that iEPS units require very little in the way of fuel, so even scaled-up versions can be fitted to small satellites to provide cost-effective and fuel-efficient thrust. Scientists in Switzerland, for instance, say they can send a shoebox-size satellite to the moon in six months with only a few drops of fuel.

As Professor Lozano said, in regards to the long term plans for the iEPS concept:

The goal is to make [CubeSats] do most of the things we already do with big satellites, except in a less expensive way. People have very big plans for these very small spacecraft.

cubesats1But in reality, even the outer Solar System is not limit when it comes to this scaled-down satellite technology. Looking even further abroad, tiny satellites could be sent into deep space to map out what lies between our Solar System and other stars, or investigate the mysteries of the Milky Way. Asteroid prospecting could also benefit from small, cost-effective probes that are capable of navigating between rocks.

And when the technology is scaled down even further, perhaps even to the nano level, millions of tiny probes could be sent out into space to study dark matter, high-energy particles, and seek out new life. Combined with new technologies like space penetrators, entire solar systems and even galaxies could be seeded with tiny space sats. Exciting possibilities indeed!

The Future of Transport: High-Speed MagLev’s

hyperloopThis past summer, Elon Musk once again impressed the world with his futuristic design for a high-speed transit tube that could take passengers from Los Angeles and San Francisco in just 30 minutes. It’s known as the Hyperloop, a “fifth form” of transportation that would utilize linear electric motors, solar panels, and air cushions to achieve speeds of up to 1290 kilometers per hour (800 mph).

Unfortunately, Musk also indicated that with his current, busy schedule, it would be many years before a working demonstration could be produced. What’s more, he was unclear on what role, if any, he would play in its creation. The project was unveiled as an open-source venture, and he called upon business investors to take up the role of making it happen.

hyperloop1However, some investors have come forward to do just that. Gathering around the entrepreneurial collaboration platform known as JumpStartFund, these enthusiasts have come together to create a corporation that will see Musk’s concept through to development. This is no small task, seeing as how the price-tag (according to Musk) would be between 6 and 10 billion dollars.

JumpStartFund launched on August 22, and aims to give entrepreneurs a network through which to both seek funding and support as well as crowdsource the idea and collaborate with others to refine it. The Hyperloop concept, put up on the site by the JumpStart team, became the platform’s flagship project within its first week of launch.

hyperloop2Dirk Ahlborn, CEO and co-founder of JumpStartFund, said in an interview back in September:

We want to be the ones that actually make things happen. So of course we need to create a corporation. Whoever decides to dedicate more time to this than just logging onto the platform deserves to be part of this company.

Because Ahlborn and his co-founders have connections with SpaceX, they were able to talk over the idea with the company’s president, Gwynne Shotwell, and get the green light to feature it on the platform. Joining them are engineers Marco Villa and Patricia Galloway, who worked for SpaceX and the US National Science Board respectively and even held directorial and vice chair positions.

hyperloop3JumpStartFund is also accepting applications from members of the site to work full-time on the Hyperloop project in exchange for equity in the company. Ahlborn has also indicated that even naming the company will be a crowdsourced effort:

We want to find a way to give everyone the ability to be a part of this project. The whole concept is always going to be on the platform. Everything is going to be very transparent, and we intend to reserve a percent of future revenues for people that work with us on the platform.

And the Hyperloop is hardly alone when it comes to the future of mass transit. On the opposite side of the US, along the Northeast Corridor, The Northeast Maglev (TNEM) company is looking to create a superconducting magnetic railway that could take passengers from New York to Washington D.C. in 60 minutes, and from Baltimore to D.C. is just 15.

scmaglev-rendering-marylandAt present, this American company – which is backed by a Japanese government bank – is testing a maglev route in Japan that runs from Nagoya to Tokyo in Japan and is planned to be completed by 2027. In the US, their efforts are aimed at replacing the nation’s aging transit infrastructure, which is unable to cope with modern demand.

As Northeast Maglev CEO and chairman Wayne Rogers said in a recent interview with Co.Exist:

What’s happening is we’re operating on 1940s and 1950s infrastructure and drowning in congestion. This isn’t pie-in-the-sky technology. This is something that you could fly to Tokyo, sit on a train, and actually ride a train that goes 311 miles per hour.

Much like the Hyperloop, the train would run on a bed of air, levitated by a series of electromagnetic coils located on the track. While similar magnetic levitation projects along the corridor have been considered in the past, they repeatedly failed due to curves that would slow down the transit process, and passengers projections were consistently too low.

scmaglev-rendering-new-jersey-high-trafficThe current maglev project plans on using tunnels to bypass the curves, and train ridership is at an all-time high. However, the realization of the project will still require significant funds. As Rogers himself projects, the first leg of the route – from D.C. to Baltimore – will cost some $10 billion. As such, the company imagines it will require some additional federal support.

The company does have some high-profile support working in its favor, though. Its advisory board includes two former transportation secretaries, former majority leader Tom Daschle, Under Armour CEO Kevin Plank, former Northwest Airlines CEO Doug Steenland, and George Pataki, Christine Todd Whitman, and Ed Rendell – the former governors of New York, New Jersey, and Pennsylvania.

scmaglev-rendering-washington-stationAnd ultimately, Rogers and his company are hopeful, citing recent changes and the enthusiasm garnered by the Hyperloop project:

[T]he concept is different, the sponsorship is different, the routing is different, and the technology is different. I think one of the things [the Hyperloop] has done – without commenting on the feasibility of the Hyperloop or not – is it’s brought people’s attention to the problem and brings America back to the things it’s good at, which is thinking big things and implementing cutting-edge technologies on terrific projects.

Who knows? In a few decades times, we could be looking at a world where high-speed maglev trains crisscross every continent, carrying people between all major cities faster than jet planes, and at a fraction of the cost. Meanwhile, intercontinental transit could be taking the form of aerospace travel, jets that fly into the lower atmosphere at hypersonic speeds. It’s important to dream big!

World’s First 3-D Printed Metal Gun

3dmetalgun-640x353Earlier this year, Distributed Defense became the source of much controversy after they unveiled the world’s first 3-D printed gun. Known as the Liberator, this single-shot weapon was entirely composed of ABS plastic, and was the first weapon that could be created using open-source software and a 3-D printer, giving anyone with access the means to build their own firearms.

Predictably, the website was shut down and the design specs were removed, thanks to an injunction filed by the U.S. Department of Defense Trade Control just a few days after the unveiling. However, the issue was far from closed, as the case of Distributed Defense and the Liberator were clearly just a drop in the bucket of a much larger trend.liberatorAnd now, just six months later, the issue is once again rearing its head as the world’s first 3-D printed metal gun was unveiled. Created by the rapid prototyping and 3-D printing company known as Solid Concepts, this 1911 Colt .45 is a major step forward in the realm of weapons that can be built by just about anyone and counted on to remain functional after firing.

The gun was built using the relatively new process known as Selective Laser Sintering (SLS), a process that combines lasers and powdered metals to create finished products. Basically, a high-powered laser is used to fuse small particles of powder together, layer by layer, until the desired shape is created. In addition to being able to create highly intricate objects, sintering is far more efficient than the machining process.

3D-Printed-Metal-Gun-Components-Disassembled-Low-Res-640x480This latest weapon was also an improvement over the Liberator in that it was able to fire over 50 rounds with considerable accuracy, whereas the Liberator broke down after just a few shots. Made of of over 30 separate 3D printed parts, the gun is composed of stainless steel and Inconel 625 (a nickel-chromium superalloy), consistent with the original Colt design.

But before people begin to worry that this is bad news, Solid Concepts was quick to point out that the gun was printed using an industrial printer, the price of which is out of range of your average citizen. In addition, the software is not open-source, meaning people can’t simply download it from any 3-D printing website and begin producing their own private arsenal.

sinteringSolid Concepts also claims that they produced this weapon to demonstrate how 3-D printing is not just for hobbyists anymore, and how sintering is a viable way to produce delicate, precise, specific consumer and professional grade products. The company said that it is currently the only 3D printing service provider with a federal firearms license, and will be looking to provide printed gun parts for legal gun owners.

Regardless, this story serves as an example of how far the technology of 3-D printing has come in just a short amount of time. From printing models with plastic, the technology is now pushing the boundaries of industrial manufacturing and bioprinting, using everything from steel and titanium to liver and kidney cells.

Give more time and refinement, we could be entering into an age where all consumer products and necessities are created from powder and individual cells, possibly even at the atomic level. For those wondering what the next industrial revolution will look like, I suggest you look no further!

And of course, Solid Concepts captured the test firing of their 1911 Colt on video. Check it out:

Alien Spotting by 2020?

alien-worldWith recent observations made possible by the Kepler space telescope, numerous planets have been discovered orbiting distant stars. Whereas previous observations and techniques could detect exoplanets, scientists are now able to observe and classify them, with the ultimate aim of determining how Earth-like they are and whether or not they can support life.

Combined with advanced astronomical techniques, the latest estimates claim that there may be are up to 50 sextillion potentially habitable planets in the universe. With their eyes on the next step, the scientific community is now preparing to launch a bevy of new space telescopes that can peer across the universe and tell us how many of those planets actually harbor life.

TESSOne such telescope is NASA’s Transiting Exoplanet Survey Satellite (TESS), which will launch in 2017. While Kepler was focused on a single patch of sky with around 145,000 stars, TESS will be equipped with four telescopes that keep track of around 500,000 stars, including the 1,000 nearest red dwarfs. TESS is expected to find thousands of orbiting, Earth-sized-or-larger planets around these stars.

But to find out whether or not any of those planets actually house life, another sophisticated telescope needs to be employed – the James Webb Space Telescope.Whereas TESS is Kepler’s successor, the James Webb Space Telescope – a joint NASA/ESA/CSA venture – is the planned successor for the Hubble Telescope and is due to launch in 2018.

TESS_Space_Telescope_Mirror37-640x425The JWST has a primary mirror that’s about five times larger than Hubble’s (pictured above), which means it can resolve much fainter signals, locating stars and other objects that have never been seen before. Because it primarily operates in the infrared band (whereas Hubble was tuned towards visible light), the JWST will also be able to see through dust clouds into hidden areas of space.

The JWST’s scientific payload includes a spectrometer that’s sensitive enough to analyze the atmosphere of distant planets. By measuring light from the parent stars, and how its reflected in the planets atmospheres, it will be able to determine if there are life-supporting elements and evidence of biological life – such as oxygen and methane.

TESS_comparisonBecause these planets are light years away, and because the reflected light is incredibly dim, the James Webb Space Telescope will only be able to do this for large planets that orbit red and white dwarfs. Still, that leaves thousands or even millions of candidates that it will be able to observe, and determine whether or not they are already inhabited by extra-terrestrial life.

And last, but not least, there’s the New Worlds Mission, which aims to put a Starshade – which is essentially a big flying space umbrella – into space. This disc would then fly between the James Webb Space Telescope and the star its observing, blocking out large amounts of light and the result “noise pollution” from nearby bright stars that the JWST isn’t observing.

Starshade_1280x720_H264With the Starshade in place, the JWST would be able to probe thousands of nearby planets for signs of life and return data to Earth that is of far greater accuracy. The New Worlds Mission is currently in the prototyping stage, but NASA hopes to procure the necessary funding by 2015 and and launch it within the JWST’s own lifetime.

Because of all this, it is now believed that by 2020 (give or take a few years) we will have the ability to directly image a distant planet and analyze its atmosphere. And if we find methane or another biological marker on just one planet, it will completely redefine our understanding of the universe and the lifeforms that inhabit it.

The answer to the question – “are we alone in the universe?” – may finally be answered, and within our own lifetime. And in the meantime, be sure to enjoy this video of the Starshade space umbrella, courtesy of New Scientist.

News From Space: MAVEN Launched

maven_launchYesterday, NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) space probe was finally launched into space. The flawless launch took place from Cape Canaveral Air Force Station’s Space Launch Complex 41 at 1:28 p.m. EST atop a powerful Atlas V rocket. This historic event, which was the culmination of years worth of research, was made all the more significant due to the fact that it was nearly scrapped.

Back in late September, during the government shutdown, NASA saw its funding curtailed and put on hold. As a result, there were fears that MAVEN would miss its crucial launch window this November. Luckily, after two days of complete work stoppage, technicians working on the orbiter were granted an exemption and went back to prepping the probe for launch.

NASA_mavenThanks to their efforts, the launch went off without a hitch. 52 minutes later, the $671 Million MAVEN probe separated from the Atlas Centaur upper stage module, unfurled its wing-like solar panels, and began making its 10 month interplanetary voyage that will take it to Mars. Once it arrives, it will begin conducting atmospheric tests that will answer key questions about the evolution of Mars and its potential for supporting life.

Originally described as a “time-machine for Mars”, MAVEN was designed to orbit Mars and examine whether the atmosphere could also have provided life support, what the atmosphere was like, and what led to its destruction. This mission was largely inspired by recent discoveries made by the Opportunity and Curiosity rovers, whose surface studies revealed that Mars boasted an atmosphere some billions of years ago.

maven_atmo1During a post launch briefing for reporters, Bruce Jakosky – MAVEN’s Principal Investigator – described MAVEN’s mission as follows:

We want to determine what were the drivers of that change? What is the history of Martian habitability, climate change and the potential for life?

Once the probe arrives in orbit around Mars, scheduled for September 22nd, 2014, MAVEN will study Mars’ upper atmosphere to explore how the Red Planet may have lost its atmosphere over the course of billions of years. This will be done by measuring the current rates of atmospheric loss to determine how and when Mars lost its atmosphere and water.

maven_atmosphereFor the sake of this research, MAVEN was equipped with nine sensors the come in three instrument suites. The first is the Particles and Fields Package – which contains six instruments to characterize the solar wind and the ionosphere of Mars – that was provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center.

The second suite is the Remote Sensing Package, which ill determine global characteristics of the upper atmosphere and ionosphere and was built by CU/LASP. And last, but not least, is the Neutral Gas and Ion Mass Spectrometer, built by Goddard, which will measure the composition of Mars’ upper atmosphere.

As for the long term benefits of the mission and what it could mean for humanity, I’d say that Dr. Jim Green – NASA’s Director of Planetary Science at NASA HQ in Washington, DC – said it best:

We need to know everything we can before we can send people to Mars. MAVEN is a key step along the way. And the team did it under budget! It is so exciting!

Judgement Day Update: Bionic Computing!

big_blue1IBM has always been at the forefront of cutting-edge technology. Whether it was with the development computers that could guide ICBMs and rockets into space during the Cold War, or the creation of the Internet during the early 90’s, they have managed to stay on the vanguard by constantly looking ahead. So it comes as no surprise that they had plenty to say last month on the subject of the next of the next big leap.

During a media tour of their Zurich lab in late October, IBM presented some of the company’s latest concepts. According to the company, the key to creating supermachines that 10,000 faster and more efficient is to build bionic computers cooled and powered by electronic blood. The end result of this plan is what is known as “Big Blue”, a proposed biocomputer that they anticipate will take 10 years to make.

Human-Brain-project-Alp-ICTIntrinsic to the design is the merger of computing and biological forms, specifically the human brain. In terms of computing, IBM is relying the human brain as their template. Through this, they hope to be able to enable processing power that’s densely packed into 3D volumes rather than spread out across flat 2D circuit boards with slow communication links.

On the biological side of things, IBM is supplying computing equipment to the Human Brain Project (HBP) – a $1.3 billion European effort that uses computers to simulate the actual workings of an entire brain. Beginning with mice, but then working their way up to human beings, their simulations examine the inner workings of the mind all the way down to the biochemical level of the neuron.

brain_chip2It’s all part of what IBM calls “the cognitive systems era”, a future where computers aren’t just programmed, but also perceive what’s going on, make judgments, communicate with natural language, and learn from experience. As the description would suggest, it is closely related to artificial intelligence, and may very well prove to be the curtain raiser of the AI era.

One of the key challenge behind this work is matching the brain’s power consumption. The ability to process the subtleties of human language helped IBM’s Watson supercomputer win at “Jeopardy.” That was a high-profile step on the road to cognitive computing, but from a practical perspective, it also showed how much farther computing has to go. Whereas Watson uses 85 kilowatts of power, the human brain uses only 20 watts.

aquasar2Already, a shift has been occurring in computing, which is evident in the way engineers and technicians are now measuring computer progress. For the past few decades, the method of choice for gauging performance was operations per second, or the rate at which a machine could perform mathematical calculations.

But as a computers began to require prohibitive amounts of power to perform various functions and generated far too much waste heat, a new measurement was called for. The new measurement that emerged as a result was expressed in operations per joule of energy consumed. In short, progress has come to be measured in term’s of a computer’s energy efficiency.

IBM_Research_ZurichBut now, IBM is contemplating another method for measuring progress that is known as “operations per liter”. In accordance with this new paradigm, the success of a computer will be judged by how much data-processing can be squeezed into a given volume of space. This is where the brain really serves as a source of inspiration, being the most efficient computer in terms of performance per cubic centimeter.

As it stands, today’s computers consist of transistors and circuits laid out on flat boards that ensure plenty of contact with air that cools the chips. But as Bruno Michel – a biophysics professor and researcher in advanced thermal packaging for IBM Research – explains, this is a terribly inefficient use of space:

In a computer, processors occupy one-millionth of the volume. In a brain, it’s 40 percent. Our brain is a volumetric, dense, object.

IBM_stacked3dchipsIn short, communication links between processing elements can’t keep up with data-transfer demands, and they consume too much power as well. The proposed solution is to stack and link chips into dense 3D configurations, a process which is impossible today because stacking even two chips means crippling overheating problems. That’s where the “liquid blood” comes in, at least as far as cooling is concerned.

This process is demonstrated with the company’s prototype system called Aquasar. By branching chips into a network of liquid cooling channels that funnel fluid into ever-smaller tubes, the chips can be stacked together in large configurations without overheating. The liquid passes not next to the chip, but through it, drawing away heat in the thousandth of a second it takes to make the trip.

aquasarIn addition, IBM also is developing a system called a redox flow battery that uses liquid to distribute power instead of using wires. Two types of electrolyte fluid, each with oppositely charged electrical ions, circulate through the system to distribute power, much in the same way that the human body provides oxygen, nutrients and cooling to brain through the blood.

The electrolytes travel through ever-smaller tubes that are about 100 microns wide at their smallest – the width of a human hair – before handing off their power to conventional electrical wires. Flow batteries can produce between 0.5 and 3 volts, and that in turn means IBM can use the technology today to supply 1 watt of power for every square centimeter of a computer’s circuit board.

IBM_Blue_Gene_P_supercomputerAlready, the IBM Blue Gene supercomputer has been used for brain research by the Blue Brain Project at the Ecole Polytechnique Federale de Lausanne (EPFL) in Lausanne, Switzerland. Working with the HBP, their next step ill be to augment a Blue Gene/Q with additional flash memory at the Swiss National Supercomputing Center.

After that, they will begin simulating the inner workings of the mouse brain, which consists of 70 million neurons. By the time they will be conducting human brain simulations, they plan to be using an “exascale” machine – one that performs 1 exaflops, or quintillion floating-point operations per second. This will take place at the Juelich Supercomputing Center in northern Germany.

brain-activityThis is no easy challenge, mainly because the brain is so complex. In addition to 100 billion neurons and 100 trillionsynapses,  there are 55 different varieties of neuron, and 3,000 ways they can interconnect. That complexity is multiplied by differences that appear with 600 different diseases, genetic variation from one person to the next, and changes that go along with the age and sex of humans.

As Henry Markram, the co-director of EPFL who has worked on the Blue Brain project for years:

If you can’t experimentally map the brain, you have to predict it — the numbers of neurons, the types, where the proteins are located, how they’ll interact. We have to develop an entirely new science where we predict most of the stuff that cannot be measured.

child-ai-brainWith the Human Brain Project, researchers will use supercomputers to reproduce how brains form in an virtual vat. Then, they will see how they respond to input signals from simulated senses and nervous system. If it works, actual brain behavior should emerge from the fundamental framework inside the computer, and where it doesn’t work, scientists will know where their knowledge falls short.

The end result of all this will also be computers that are “neuromorphic” – capable of imitating human brains, thereby ushering in an age when machines will be able to truly think, reason, and make autonomous decisions. No more supercomputers that are tall on knowledge but short on understanding. The age of artificial intelligence will be upon us. And I think we all know what will follow, don’t we?

Evolution-of-the-Cylon_1024Yep, that’s what! And may God help us all!

Space Tourism: The World View Balloon

near-space_balloonWhen the Space Age began, some five decades ago, there were many who predicted that commercial space flight would follow shortly thereafter. This included everything from passenger flights into space, orbital space stations, and even space tourism. Naturally, these hopes seem quite naive in hindsight, but recent events are making them seem feasible once more.

Consider Virgin Galactic, a commercial aerospace carrier that will begin taking passengers into Low-Earth Orbit (LEO) beginning next year. And there’s Inspiration Mars, a private company that wants to send a couple on a round trip to visit the Red Planet. And now, there’s World View Enterprises, a company that plans to send to start sending passengers on a near-space balloon ride beginning in 2016.

near-space_balloon1Based in Tucson, Arizona, World View is a start-up that is looking to entice people into the budding field of space tourism by offering people a chance to get a taste of space without actually going there. Going into space is defined as traveling 100 km (62 miles) from the Earth’s surface, whereas their balloon ride will take passengers to a height of 30 km (18.6 miles), where they will be treated to a spectacular view of the Earth

World View Enterprises recently obtained approval from the US Federal Aviation Administration for its proposed balloon experiences, which will cost US $75,000 a ride, and are projected to begin in 2016. Each flight will consist of two balloon pilots and up to six passengers, which will be contained within a cylindrical capsule that comes equipped with heating and its own air-supply.

near-space_balloon2According to the company’s plan, the capsule – which measures 6 meters in length and 3 in width (approx. 20 x 10 feet) – will be deployed below a parasail (used for recovery) and tethered to a 400,000 cubic meter (14 million cubic ft) helium balloon, which will provide the lift needed to bring the capsule and its occupants to 30 km in altitude or Low-Earth Orbit.

Might sound a little dangerous to some, but the FAA has determined that World View’s design meets the engineering and environmental challenges posed by Low-Earth Orbit. They stressed that the capsule be designed and tested as if it were going to have long-term exposure in space, even though it will not exceed altitudes much above 30 km, and assigned it a safety factor of 1.4 – the same as that required of manned space systems.

near-space_balloon5The flight itself is projected to last about four hours, with the ascent taking 1.5-2 hours. The capsule will then remain at an altitude of 30 km for about two hours, during which time the semi-space tourists will be free to move about the cabin and take in the view. Unfortunately, they will not experience weightlessness during this period.

That’s comes after, when the capsule is cut off from the balloon and begins to fall towards Earth. Once it gains enough speed, the parafoil will provide sufficient lift to slow the descent and bring the passengers in for a safe, controlled landing. Before touching down, the capsule will deploy a set of skids and lands much the same way a paraglider does.

near-space_balloon4All in all, the balloon ride being suggested by World View does appear to hit many of the key points on the space tourism agenda. These include seeing black sky and the curvature of the Earth, and having a view of the planet that only astronauts are ever treated to. That may very well add up to an experience that is as good as being in space without technically getting there.

The only question is, will enough passengers line up for an amazing day’s flight that costs a startling $75K? Only time will tell. One thing is fore sure though. The dream of space tourism appears to finally be upon us, though it is a few decades late in coming. Today’s dreams do tend to become tomorrow’s reality, though they sometimes take longer than expected.

And be sure to enjoy this promotional video from World View Enterprises showing their concept in action:

The Future is Here: The Copenhagen Wheel

copenhagen_wheelFans of the cable show Weeds ought to instantly recognize this invention. It was featured as a product invented by one of the characters while living (predictably) in Copenhagen. In addition, it was the subject of news stories, articles, design awards, and a whole lot of public interest. People wanted to get their hands on it, and for obvious reasons.

It’s known as the Copenhagen Wheel, a device invented by MIT SENSEable City Lab back in 2009 to electrify the bicycle. Since that time, engineers at MIT have been working to refine it in preparation for the day when it would be commercially available. And that time has come, as a new company called Superpedestrian announced that it has invested $2.1 million in venture capital to make the device available to the public.

copenhagen_wheel1Superpedestrian founder Assaf Biderman, who is also the SENSEable City lab associate director and one of the creators of the wheel, along with lab director Carlo Ratti, had this to say:

The project touched an exposed nerve somehow. Aside from news coverage and design awards, people were wanting it. Over 14,000 people emailed saying ‘I want to buy it, sell it, make it for you.

Three years after inventing it, Biderman finally decided that it was time to spin off a company to make it happen. MIT filed all the relevant patents, and Superpedestrian acquired exclusive licenses to the Copenhagen Wheel technology. And by late November, they plan to launch the wheel to the public for the very first time.

copenhagen_wheel2And though the much of the facts are being carefully guarded in preparation for the release, some details are already known. For example, the wheel can be fitted to almost any bike, is controlled by sensors in the peddles, and has a power assist feature that doesn’t require any work on the part of the rider. And according to Biderman, its range “will cover the average suburban commute, about 15 miles to and from work and back home.”

On top of that, a regenerative braking system stores energy for later use in a lithium battery. The wheel also comes with an app that allows users to control special features from their smartphone. These include being able to lock and unlock the bike, select motor assistance, and get real-time data about road conditions. An open-source platform called The Superpedestrian SDK also exists to allow developers to make on their own apps.

smartwheelrotatingInterestingly enough,the Copenhagen Wheel also has a rival, who’s appearance on the market seems nothing short of conspiratorial. Its competitor, the FlyKly Smart Wheel, a device which has raised over $150,000 on Kickstarter so far. It is extremely similar to the Copenhagen Wheel in most respects, from its electrical assistance to the fact that it can be integrated via smartphone.

According to Biderman, the appearance of the Smart Wheel is just a coincidence, though it is similar to their product. And her company really doesn’t have to worry about competition, since the Copenhagen Wheel has years of brand recognition and MIT name behind it. In terms of the the target audience, Biderman says that they are looking at targeting city dwellers as well as cyclists:

If you’re an urbanite, you can use it to move all around, and go as far as the edges of most cities with this quite easily. You overcome topographical challenges like hills. The point is to attract more people to cycling.

Though no indication has been given how much an individual unit will cost, it is expected to have a price point that’s competitive with today’s e-bikes.

copenhagen_wheel3The FlyKly Smart Wheel, by comparison, can be pre-ordered for $550 apiece. In total, that campaign has raised $301,867 (their original goal was $100,000) since opening on Oct. 16th. As a result, they have been able to reach their first “stretch goal” of producing a 20″ wheel. If they can reach $500,000 before the campaign closes on Nov. 25th, they will be able to deliver on their other goals: a motor brake and a glow in the dark casing.

For some time, designers and engineers have been trying to find ways to make alternative transportation both effective and attractive. Between these designs and a slew of others that will undoubtedly follow, it looks like e-bicycling may be set to fill that void. Combined with electric cars, self-driving cars, hydrogen cars, robotaxis, podcars, and high speed trains, we could be looking at the revolution in transit that we’ve been waiting for.

Immortality Inc: Google’s “Calico”

calico-header-640x353Google has always been famous for investing in speculative ventures and future trends. Between their robot cars, Google Glass, the development of AI (the Google Brain), high-speed travel (the Hyperloop), and alternative energy, their seems to be no limit to what Musk and Page’s company will take on. And now, with Calico, Google has made the burgeoning industry of life-extension its business.

The newly formed company has set itself to “focus on health and well-being, in particular the challenge of aging and associated diseases.” Those were the words of Google co-founder Larry Page, who issued a two-part press release back in September. From this, it is known that Calico will focus on life extension and improvement. But in what way and with what business model, the company has yet to explain.

DNA-1What does seem clear at this point is that Art Levinson, the chairman of Apple and former CEO of Genentech (a pioneer in biotech) will be the one to head up this new venture. His history working his way from a research scientist on up to CEO of Genentech makes him the natural choice, since he will bring medical connections and credibility to a company that’s currently low on both.

Google Health, the company’s last foray into the health industry, was a failure for the company. This site, which began in 2008 and shut down in 2011, was a personal health information centralization service that allowed Google users to volunteer their health records. Once entered, the site would provide them with a merged health record, information on conditions, and possible interactions between drugs, conditions, and allergies.

Larry_PageIn addition, the reasons for the company’s venture into the realm of health and aging may have something to do with Larry Page’s own recent health concerns. For years, Page has struggled with vocal nerve strain, which led him to make a significant donation to research into the problem. But clearly, Calico aims to go beyond simple health problems and cures for known diseases.

google.cover.inddIn a comment to Time Magazine, Page stated that a cure for cancer would only extent the average human lifespan by 3 years. They want to think bigger than that, which could mean addressing the actual causes of aging, the molecular processes that break down cells. Given that Google Ventures included life extension technology as part of their recent bid to attract engineering students, Google’s top brass might have a slightly different idea.

And while this might all sound a bit farfetched, the concept of life-extension and even clinical immortality have been serious pursuits for some time. We tend to think of aging as a fact of life, something that is as inevitable as it is irreversible. However, a number of plausible scenarios have already been discussed that could slow or even end this process, ranging from genetic manipulation, nanotechnology, implant technology, and cellular therapy.

Fountain_of_Eternal_Life_cropWhether or not Calico will get into any of these fields remains to be seen. But keeping in mind that this is the company that has proposed setting aside land for no-hold barred experimentation and even talked about building a Space Elevator with a straight face. I wouldn’t be surprised if they started building cryogentic tanks and jars for preserving disembodies brains before long!

Judgement Day Update: Banning Autonomous Killing Machines

drone-strikeDrone warfare is one of the most controversial issues facing the world today. In addition to ongoing concerns about lack of transparency and who’s making the life-and-death decisions, there has also been serious and ongoing concerns about the cost in civilian lives, and the efforts of both the Pentagon and the US government to keep this information from the public.

This past October, the testimonial of a Pakistani family to Congress helped to put a human face on the issue. Rafiq ur Rehman, a Pakistani primary school teacher, described how his mother, Momina Bibi, had been killed by a drone strike. His two children – Zubair and Nabila, aged 13 and 9 – were also injured in the attack that took place on October 24th of this year.

congress_dronetestimonyThis testimony occurred shortly after the publication of an Amnesty International report, which listed Bibi among 900 other civilians they say have been killed by drone strikes since 2001. Not only is this number far higher than previously reported, the report claims that the US may have committed war crimes and should stand trial for its actions.

Already, efforts have been mounted to put limitations on drone use and development within the US. Last year, Human Rights Watch and Harvard University released a joint report calling for the preemptive ban of “killer robots”. Shortly thereafter, Deputy Defense Secretary Ashton Carter signed a series of instructions to “minimize the probability and consequences of failures that could lead to unintended engagements.”

campaignkillerrobots_UNHowever, these efforts officially became international in scope when, on Monday October 21st, a growing number of humans rights activists, ethicists, and technologists converged on the United Nations Headquarters in New York City to call for an international agreement that would ban the development and use of fully autonomous weapons technology.

Known as the “Campaign To Stop Killer Robots,” an international coalition formed this past April, this group has demanded that autonomous killing machines should be treated like other tactics and tools of war that have been banned under the Geneva Convention – such as chemical weapons or anti-personnel landmines.

UAVsAs Jody Williams. a Nobel Peace Prize winner and, a founding member of the group said:

If these weapons move forward, it will transform the face of war forever. At some point in time, today’s drones may be like the ‘Model T’ of autonomous weaponry.

According to Noel Sharkey, an Irish computer scientist who is chair of the International Committee for Robot Arms Control, the list of challenges in developing autonomous robots is enormous. They range from the purely technological, such as the ability to properly identify a target using grainy computer vision, to ones that involve fundamental ethical, legal, and humanitarian questions.

As the current drone campaign has shown repeatedly, a teenage insurgent is often hard to distinguish from a child playing with a toy. What’s more, in all engagements in war, there is what is called the “proportionality test” – whether the civilian risks outweigh the military advantage of an attack. At present, no machine exists that would be capable of making these distinctions and judgement calls.

X-47B_over_coastlineDespite these challenges, militaries around the world – including China, Israel, Russia, and especially the U.S. – are enthusiastic about developing and adopting technologies that will take humans entirely out of the equation, often citing the potential to save soldiers’ lives as a justification. According to Williams, without preventative action, the writing is on the wall.

Consider the U.S. military’s X-47 aircraft, which can take off, land, and refuel on its own and has weapons bays, as evidence of the trend towards greater levels of autonomy in weapons systems. Similarly, the U.K. military is collaborating with B.A.E. Systems to develop a drone called the Taranis, or “God of Thunder,” which can fly faster than the speed of sound and select its own targets.

campaign_killerrobotsThe Campaign to Stop Killer Robots, a coalition of international and national NGOs, may have only launched recently, but individual groups have been to raise awareness for the last few years. Earlier this month, 272 engineers, computer scientists and roboticists signed onto the coalition’s letter calling for a ban. In addition, the U.N. is already expressed concern about the issue.

For example, the U.N. Special Rapporteur issued a report to the General Assembly back in April that recommended states establish national moratorium on the development of such weapons. The coalition is hoping to follow up on this by asking that other nations will join those already seeking to start early talks on the issue at the U.N. General Assembly First Committee on Disarmament and International Security meeting in New York later this month.

AI'sOn the plus side, there is a precedent for a “preventative ban”: blinding lasers were never used in war, because they were preemptively included in a treaty. On the downside, autonomous weapons technology is not an easily-defined system, which makes it more difficult to legislate. If a ban is to be applied, knowing where it begins and ends, and what loopholes exist, is something that will have to be ironed out in advance.

What’s more, there are alternatives to a ban, such as regulation and limitations. By allowing states to develop machinery that is capable of handling itself in non-combat situations, but which require a human operator to green light the use of weapons, is something the US military has already claimed it is committed to. As far as international law is concerned, this represents a viable alternative to putting a stop to all research.

Overall, it is estimated that we are at least a decade away from a truly autonomous machine of war, so there is time for the law to evolve and prepare a proper response. In the meantime, there is also plenty of time to address the current use of drones and all its consequences. I’m sure I speak for more than myself when I say that I hope its get better before it gets worse.
