The race for taxis, lifeboats and beyond in space


War Games

Published February 14, 2013

America is a giant leap closer to developing a new, made-in-the-USA spacecraft to launch astronauts into space once again.

The Dragon capsule from Space Exploration Technologies (SpaceX) returned successfully from the first private cargo mission in Oct. 2012, making it a clear leader in the race to build a spacecraft suitable for humans. But oddsmakers are scrambling to revise the leaderboard: Lockheed Martin just announced it would join forces with Sierra Nevada to build the competition, the futuristic Dream Chaser.

The Dream Chaser is the only spacecraft with wings. It can carry as many as seven astronauts to space and is designed to land on a conventional runway.  Along with the CST-100 capsule from Boeing, these three shuttles are locked in a race to bring manned spaceflight back to the U.S.

Space dominance is essential to national security, experts agree.


‘Lockheed Martin has joined our Dream Chaser team … [now] how do we get this vehicle really fit to fly safely?’

– Mark Sirangelo, Sierra Nevada’s executive vice president and chairman of its space systems division


Lockheed Martin’s history should help. The company has extensive experience building spacecraft and high-performance aircraft composite structures – the company will be building Dream Chaser’s vehicle composite structure.

In this competition, formally known as the Commercial Crew Program (CCP) initiative, NASA partners with the private sector to leverage the Agency’s five decades of human spaceflight experience against private sector experience and innovation.

Since the launch of this challenge at the close of the space shuttle program, American companies have been competing to restore human spaceflight capabilities to the U.S. with a safe, reliable and cost-effective means into and out of low-Earth orbit for government and commercial customers – in a way, a space taxi.

With the end of the Space Shuttle program, the U.S. lost its own transportation capabilities to the International Space Station. Once CCP is achieved, Americans will no longer have to rely on the expensive lift from Russia’s Soyuz rockets.

Space Taxi or Lifeboat
The teams are competing to create a system that will deliver equipment and a minimum of four astronauts to the space station and return them to Earth at least twice a year.

In the event of an emergency on the launch pad, during launch or ascent, the competing teams must have solutions to assure crew safety.

If there is an emergency while in space, the spacecraft must be able to serve as a 24-hour safe haven, sort of like a space lifeboat.  It also needs to be able to stay docked to the station for at least 210 days.

Of the three designs, NASA will ultimately choose its favorite for ferrying American astronauts to and from the International Space Station, but the end result could be more than one spacecraft to provide safe, reliable and less expensive space access.

Roadmap to Space
These three companies are now beginning the first phase of the certification efforts to confirm their commercial spacecraft is safe to carry crews to the station.

During Phase 1 — which is expected to last about 15 months from Jan. 22, 2013, through May 30, 2014 — NASA and the companies will establish that each spacecraft, launch vehicle, ground operations and mission control center meet flight safety and performance requirements.

Phase 2 next year will mark the start of final development, building, verifying and validating the systems are ready to fly astronauts by 2017.

Dream Chaser, for example, completed its helicopter drop test in late 2012 and has a suborbital test scheduled for this year and an orbital test in 2014. SpaceX is planning for a pad abort test and in-flight abort test, while Boeing will be verifying its spacecraft and launch vehicle compatibility.

Moon and Beyond
Providing the CCP program is successful, NASA will then become a customer using the new spacecraft to transport American flight crew to the International Space Station to continue their critical science research.

While NASA is working with the private sector for low-Earth orbit International Space Station cargo re-supply and crew transportation, NASA has retained responsibility for travel beyond the moon.

As the lead in deep-space exploration, the agency is developing the Orion spacecraft crew capsule and the heavy lift rocket Space Launch System (SLS).

SLS and Orion will provide an entirely new capability for human exploration beyond low-Earth orbit and make new exploration missions of the solar system possible, the agency says.

Earth-buzzing asteroid worth $195 billion, space miners say

By Mike Wall

The space rock set to give Earth a historically close shave this Friday, Feb. 15, may be worth nearly $200 billion, prospective asteroid miners say.

The 150-foot-wide asteroid 2012 DA14 — which will zoom within 17,200 miles of Earth on Friday, marking the closest approach by such a large space rock that astronomers have ever known about in advance — may harbor $65 billion of recoverable water and $130 billion in metals, say officials with celestial mining firm Deep Space Industries.


‘While this week’s visitor isn’t going the right way for us to harvest it, there will be others that are.’

– Deep Space chairman Rick Tumlinson


That’s just a guess, they stressed, since 2012 DA14’s composition is not well known and its size is an estimate based on the asteroid‘s brightness.

The company has no plans to go after 2012 DA14; the asteroid’s orbit is highly tilted relative to Earth, making it too difficult to chase down. But the space rock’s close flyby serves to illustrate the wealth of asteroid resources just waiting to be extracted and used, Deep Space officials said.

“While this week’s visitor isn’t going the right way for us to harvest it, there will be others that are, and we want to be ready when they arrive,” Deep Space chairman Rick Tumlinson said in a statement Tuesday.

Deep Space Industries wants to use asteroid resources to help humanity expand its footprint out into the solar system. The company plans to convert space rock water into rocket fuel, which would be used to top up the tanks of off-Earth satellites and spaceships cheaply and efficiently.

Asteroidal metals such as iron and nickel, for their part, would form the basis of a space-based manufacturing industry that could build spaceships, human habitats and other structures off the planet.

The idea is to dramatically reduce the amount of material that needs to be launched from Earth, since it currently costs at least $10 million to send 1 ton of material to high-Earth orbit, officials said.

“Getting these supplies to serve communications satellites and coming crewed missions to Mars from in-space sources like asteroids is key if we are going to explore and settle space,” Tumlinson said.

Deep Space Industries is just one of two asteroid-mining firms that have revealed their existence and intentions in the past 10 months. The other is Planetary Resources, which has financial backing from billionaires such as Google execs Larry Page and Eric Schmidt.

Deep Space aims to launch a phalanx of small, robotic prospecting probes called Fireflies in 2015. Sample-return missions to potential targets would occur shortly thereafter, with space mining operations possibly beginning around 2020.

Planetary Resources also hopes its activities open the solar system up for further and more efficient exploration. The company may launch its first low-cost prospecting space telescopes within the next year or so.

Asteroid 2012 DA14: 5 Surprising Facts About Friday’s Earth Flyby

    5Asteroids like 2012 DA14 fly by Earth every 40 years

While there is no chance that asteroid 2012 DA14 will hit Earth this Friday, the asteroid’s flyby is history-making for several other reasons.

  • 1This is asteroid 2012 DA14’s closest pass ever


    Using intricate mapping techniques, researchers have already plotted the 150-foot space rock’s trajectory far out into the future. When the asteroid flies by Earth, the planet’s gravity will force the asteroid into a new orbit that won’t bring it this close to the Earth for years to come. [Asteroid 2012 DA14’s Close Shave Explained (Infographic)]

  • 2Asteroids like 2012 DA14 have hit Earth before


    Scientists think the “Tunguska Event” over Siberia in 1908 was caused by a 100-foot asteroid. This space rock exploded in midair, leveling trees across 825 square miles in the region.

    If 2012 DA14 did enter Earth’s atmosphere, it probably would react similarly — exploding above the ground and causing destruction over a wide area, but not endangering human civilization or causing other major global problems.

  • 32012 DA14 was discovered by amateur astronomers


    Asteroid 2012 DA14 was discovered by a team of amateur astronomers affiliated with the La Sagra Sky Survey at the Astronomical Observatory of Mallorca in southern Spain on Feb. 23, 2012.

    At the time, the asteroid was about 2.7 million miles away from Earth. After the group reported the finding, NASA and other space agency scientists began tracking the asteroid to track its path and make sure it posed no threat to the planet.

  • 4Its closest approach point will be over Sumatra

    Alexandra Bolling, NRAO/AUI/NSF

    On Friday, when asteroid 2012 DA14 approaches within 17,200 miles of Earth, it will be over Sumatra, Indonesia at its closest point while zipping by the planet. That’s just one-thirteenth the average distance from Earth to the moon.

    At its closest approach on Friday at 2:24 p.m. EST (1924 GMT), the asteroid will be 5,000 miles closer to Earth than the ring of GPS, weather and communications satellites in orbit around the planet. Still, the satellites and the planet are safe from impact, researchers say.

  • 5Asteroids like 2012 DA14 fly by Earth every 40 years


    Based on a statistical analysis, NASA researchers have found that asteroids like 2012 DA14 only graze Earth this closely once every 40 years or so. Similar asteroids can actually hit the Earth once every 1,200 years.

    Larger asteroids are even less likely to give the planet such a close shave. NASA researchers say that their Near Earth Object Program has helped to detect and track 90 percent of the largest near-Earth asteroids, and so far none of these behemoths are known to pose an impact threat in the foreseeable future.

    NASA will also be live-streaming the flyby via a telescope at NASA’s Marshall Space Flight Center in Huntsville, Ala. from 6 p.m. to 9 p.m. ET (2100 to 0200 Feb. 16 GMT) on Friday.

An asteroid half the size of a football field will buzz close by Earth on Friday, coming closer than many weather satellites, but there is absolutely no chance the space rock will hit the planet, NASA says.

The asteroid 2012 DA14 will approach within 17,200 miles of Earth when it zips by the planet on Friday (Feb. 15). It will be 5,000 miles closer than the ring of weather, communications and GPS navigation satellites that orbit the Earth, but it poses no impact threat, NASA scientists assured.

According to detailed observations of the 150-foot 2012 DA14 since its discovery last year, “there is no chance that the asteroid might be on a collision course with Earth,” NASA officials said in a statement.


‘There is no chance that the asteroid might be on a collision course with Earth.’

But the space rock encounter will mark the closest-ever known Earth flyby of an asteroid the size of 2012 DA14, with NASA scientists and astronomers around the world preparing to take advantage of the event to take a close look at how asteroids work.

One study in particular seeks to pin down exactly how the asteroid spins on its axis.

“Knowing the direction of spin is essential to accurately predicting its future path, and thus determining just how close it will get to Earth in the coming years,” study leader Michael Busch of the National Radio Astronomy Observatory (NRAO) said in a statement.

Busch and his colleagues will use two huge radio telescopes in New Mexico, the Very Large Array and Very Long Baseline Array, along with NASA’s Goldstone radar antenna in California in an attempt to determine the direction of asteroid 2012 DA’s spin.

The telescopes seek out so-called “speckles” in the radio signals reflected by the asteroid’s uneven surface, and then compare which observatory detected the speckles first in order to determine the spin direction.

Knowing an asteroid’s spin is key to understanding how a space rock radiates heat from absorbed sunlight over time. That, in turn, can allow astronomers to project how an asteroid’s orbit can change over long periods as it circles the sun.

Asteroids, like Earth, have a warmest part of their day, during which time they develop a hotspot that can be observed in infrared light. Later, the asteroid emits the absorbed radiation back out into space, which can serve as a gentle — but firm — jet-like push forward, researchers said.

The phenomenon is called the “Yarkovsky effect” after the 19th-century Russian engineer I.O. Yarkovsky, who first identified it.

“When the asteroid passes close to the Earth or another large body, its orbit can be changed quickly by the gravitational effect of the larger body, but the Yarkovsky Effect, though smaller, is at work all the time,” Busch said.

Asteroid 2012 DA14 was discovered in 2012 by astronomers with the La Sagra Sky Survey at the Astronomical Observatory of Mallorca in Spain. The asteroid will make its closest approach to Earth at 2:24 p.m. EST (1924 GMT) Friday, at which time it may be visible in telescopes and binoculars to observers in Asia, Australia and Europe, where the local time will be nighttime.

Pluto may have been demoted, but its family is getting bigger and bigger. Now, two of the dwarf planet’s tiniest moons need names — but rather than leaving the Plutonian satellites’ naming ceremony to astronomers, that honor has fallen to you.

The discoverers of Pluto’s smallest moons — measuring only 15 to 20 miles across — have designated the moons “P4″ and “P5,” but it’s about time that they grow up and get some real names. Discovered in 2011 and 2012 by the Hubble Space Telescope, this tiny duo joins Charon, Nix and Hydra in a very close-knit family of objects orbiting Pluto.

ANALYSIS: Pluto Now Has Five (Yes, Five) Moons


‘The Greeks were great storytellers and they have given us a colorful cast of characters to work with.’

– Mark Showalter, Senior Research Scientist at the Carl Sagan Center of the SETI Institute


All of the objects were named after Hades and the underworld in ancient Greek mythology. Hades, god of the underworld, who was also known as “Plouton” (meaning “Rich One”), was Latinized by the Romans to, simply, Pluto. And the ninth planetary body from the sun was given that name by 11-year old schoolgirl Venetia Burney shortly after the small world was discovered by Clyde Tombaugh at Lowell Observatory in 1930. The mythological name for the dark and cold world on the outskirts of the solar system has now been inherited by Pluto’s satellites.

So, the SETI Institute has launched a new website called “Pluto Rocks” to decide new names for P4 and P5. Of the possible mythological names, the following can be selected: Acheron, Alecto,Cerberus, Erebus, Eurydice, Hercules, Hypnos, Lethe, Obol, Orpheus, Persephone and Styx. You can also make your own suggestions.

ANALYSIS: Pluto: Not a Planet; Still Very Interesting

“The Greeks were great storytellers and they have given us a colorful cast of characters to work with,” said Mark Showalter, Senior Research Scientist at the Carl Sagan Center of the SETI Institute in Mountain View, Calif., in a press release.

Voting will remain open till Feb. 25, when the P4/P5 discovery team will take the winning suggestions to the International Astronomical Union so the satellite pair can officially be named.

On Monday (Feb. 11) at 11 a.m., two astronomers involved in the P4/P5 discoveries — Mark Showalter and Hal Weaver, of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland — will be available live to take your questions about the naming of these moons via a special Google+ hangout. If you want to get involved, be sure to use the #PlutoRocks hashtag on Twitter, the SETI Institute Facebook page and the Google hangout.

ANALYSIS: Pluto May Live in a Rough Neighborhood

The naming of P4 and P5 may seem frivolous, but this more than a public outreach project. As NASA’s New Horizons probe flies through interplanetary space toward Pluto, in July 2015 the world will be awestruck by the first close-up photographs of dwarf planet Pluto and its largest companion Charon. The Plutonian moons will likely become household names (and the debate as to the planetary status of Pluto will likely be reignited).

But like any story from the underworld, there is a sinister back-story.

Last year, when Hubble spotted P4 and P5, concern mounted for the possibility of more, sub-resolution debris that may be hanging in Pluto orbit. The current plan for New Horizons is to fly straight between Pluto and Charon (only 6,200 miles from the surface of Pluto, pictured top), but if there’s a cloud (or ring) of debris or many smaller moonlets, there could be a substantial collision risk. This has prompted the NASA New Horizons Team — headed by Alan Stern — to formulate a “bale out” plan should the risk be deemed too great. This means mission managers may opt to command New Horizons to carry out its much anticipated flyby further away from Pluto and any potential dangers that lay in wait.

So, for now, astronomers are carefully surveying the volume of space around Pluto, looking for any hint of the hypothetical debris that may be hiding there.

The hypersonic spaceplanes of yesteryear

By Amy Shira Teitel

Published February 11, 2013

Discovery News

  • spaceliner of of yesteryear.jpg

    A scan of the original Dornberger spaceplane.

Last month, the German Aerospace Center announced its SpaceLiner.

This still-on-paper hypersonic suborbital spaceplane is theoretically capable of taking up to 50 passengers at a time to destinations halfway across the world in a few hours. It’s an exciting prospect, seeing the curvature of the Earth during a business trip.

But it isn’t a new idea. A host of science fiction writers have explored this, as did Walter Dornberger, former director of the V-2 program at Peenemunde in Germany, in 1956.

In 1952, Dornberger was a new immigrant to the United States working as a guided missile consultant for Bell Aircraft in Ohio. He pitched the idea of a hypersonic manned glider to the Air Force as an efficient and reusable precision bomber. The Air Force, intrigued, pursued the idea; it became the basis of the failed Dyna-Soar program. But for Dornberger, a hypersonic gliding bomber was a step on the way to suborbital hypersonic air travel.

ANALYSIS: When the Dyna-Soar Went Extinct

Inspired by the rapid growth of aviation – from the Wright brothers’ first flight to Mach 2 in half a century – he imagined a future where hypersonic passenger flights would be commonplace in another 25 years. But the first flights could be sooner. Writing in 1956, he saw that the nation had the technology to start exploring the world of hypersonic air travel with glider mounted on boosters. He called them Ultra Planes, and imagined them taking off from commercial airports around the world.

A glider would be mounted on the “back” of a booster such that the flat, gliding bottoms of both vehicles faced the same way. Once mated, the 90-foot tall pair would be turned vertically and loaded on a train that would carry it, by rail, to its underground launch canyon – image a missile silo big enough for crews to access both vehicles for things like fueling and maintenance. Passengers would arrive at the canyon, which would have an ordinary gate number, by bus since it would be too risky to connect a launch canyon to the terminal by jetway.

With the vehicle ready, the crew and passengers would board, the latter sitting in swiveling chairs that would keep them upright throughout the journey. Once their seat belts were firmly fastened, the booster would roar to life and launch, carrying the glider aloft with it.

ANALYSIS: How Neil Armstrong Saved the Dyna-Soar

For the first minute and a half, the glider’s pilot would be in control of both vehicles; the booster’s skeleton crew would be on standby. Then the stages would separate. The glider would slide off guide rails on the booster’s “back” and the pilot would ignite its engine. The glider would rocket up to 140,000 feet at a top speed of 8,400 miles per hour. At the same time, the booster’s crew would take control of their vehicle and return to the airport for refueling and launch with another glider in tow.

Pilot-controlled sun filters on the window’s would ensure passengers had a safe view of the curvature of the Earth as the glider reached its peak altitude. Then, as dictated by the flight plan, the glider’s pilot would shut off its engine and begin a steady glide his designated airport. The remaining ride would be silent and pleasant with stunning views unhampered by clouds out of every window. Stars that we never see from Earth would be as bright as the moon.

The glider would land, unpowered, like a traditional airplane on a runway. Passengers would disembark by a rolling stairway right onto the tarmac then the glider would be towed to a launch canyon where it would be mated to another booster and fueled for its next launch.

ANALYSIS: NASA’s Next Capsule to Land Like a Helicopter?

The few details on the SpaceLiner suggest it will follow more or less this idea laid out by Dornberger in the 1950s. The SpaceLiner will launch passengers up to 50 miles high at Mach 24 (roughly the design limit of Dyna-Soar) before gliding in at 15,000 mph for a runway landing. SpaceLiner’s project coordinator Martin Sippel expects to start gathering funds in 10 years an to have full operations up and running by 2050.

Sippel’s timeline is about the same as Dornberger’s was in 1956, but hopefully the SpaceLiner will have more luck than the ultra planes. Because traveling through (near) space as a regular airline passenger would be absolutely incredible.

The blimps are back! Massive airship off to a flying start

By Jesse Emspak

Published February 06, 2013

Discovery News

Blimps and Zeppelins plied the skies in the early part of the 20th century, carrying passengers and cargo and even serving as military aircraft during the World Wars. But it didn’t take long for airplanes to replace dirigibles for commercial and military flight and by the middle of the 20th century, airships were mostly used for advertising, sightseeing and surveillance.

But blimps may be back. Montabello, Calif.-based Aeros is working on a rigid airship that can fly like a plane and float like a balloon. If realized, the 500-foot-long Aeroscraft would greatly alter the way cargo is shipped. The craft is designed to take off vertically and cruise at up to 130 mph at an altitude of 12,000 feet. It will be able to travel thousands of miles on a single tank of fuel, carrying 66 tons of cargo — that’s three times the capacity of a C-130 and half that of the C-5, the largest military aircraft flown by the United States.

“This vehicle doesn’t need infrastructure,” Munir Tojo-Verge, the flight control systems engineer at Aeros, told Discovery News. “It could even land on water.”

PHOTOS: Blimplike Craft Hauls Tons of Cargo Anywhere

The Aeroscraft could serve both military and humanitarian efforts, delivering extremely heavy loads to areas without transportation infrastructure, such as roads, train tracks or airports.

Aeros recently tested a 230-foot-long prototype and has received $35 million from DARPA and NASA to get a full-sized version off the ground.

The Aeroscraft has a rigid shell made of a lightweight, carbon-fiber composite and has special honeycomb-like chambers designed to hold helium. The helium is housed separately in compression tanks. To fly, the compressed helium is released into the chambers. To sink, the helium is pumped back into the tanks and replaced with air. That eliminates the need for ballast. And because helium is nonflammable, there is no risk of a Hindenburg-like explosion.

The gas pressure inside isn’t much different from the outside air, so even if one were to put a hole in the skin of the Aeroscraft, the gas wouldn’t escape very fast. Blimps, by contrast, are under high pressure, so they deflate much faster.

A set of turboprop engines like those on a plane provide thrust, combined with another type that Tojo-Verge said he could not discuss. The airship’s arrowhead shape keeps it stable at higher speeds and helps give it lift.

NEWS: Schools of Sleeper Drones Could Swim Future Seas

All this makes the Aeroscraft much different from blimps, which are basically flexible, helium-filled balloons outfitted with propellers to move and steer, or zeppelins, which have rigid frames containing lots of small, helium-filled balloons called ballonets. Both types of airship need ballast and are difficult to maneuver in rough weather. The zeppelins of the 1930s also needed ground crews with ropes to wrangle the craft to the ground. The Aeroscraft won’t require that.

For cost and capability, the Aeroscraft compares well with helicopters. The biggest helicopter available now is the Sikorsky Skycrane, which travels at 126 mph and is able to carry 10 tons. These copters are often used in rescue missions and to carry heavy equipment. But they cost a lot to operate and their range is only 230 miles with a maximum load of fuel. The Aeroscraft will have a similar speed, carry much more cargo and be able to travel much farther.

While the Aeroscraft is technologically advanced, the next step is making airship transport a viable business, which may be harder than it sounds. Jose Holguin-Veras, director of the Center for Infrastructure, Transportation, and the Environment at Rensselaer Polytechnic Institute, said it would take a lot of airships to make a dent in the service area they aim to fulfill and he’s skeptical that the market will be large enough to give way to that many vehicles.

He cited the 2010 earthquake in Haiti as an example. Some 316,000 people died, 300,000 were injured and about 1.8 million people needed immediate food and supplies. Getting enough supplies to Port-au-Prince would have required hundreds of Aeroscraft airships — each one capable of carrying enough cargo for only about 3,000 people. Most of the supplies were delivered by truck from the neighboring Dominican Republic because even with the airport out of commission there was enough roadway left to get the supplies in after they were flown to Santo Domingo.

Airships may have a role for disasters in remote locations, Holguin-Veras said. “Maybe for something like a blackout in Vermont in winter,” he said, where roads were impassable and the airport wasn’t working, and the amount of cargo needed was small. In that case an Aeroscraft might deliver a generator or two, or fuel for a small town.

In terms of cargo-shipping, the Aeroscraft may not be able to compete with ocean ships or trains, Holguin-Veras said. Shipping of any kind is a tradeoff between how fast cargo has to move, how much can be carried and the cost of moving it. A plane is an expensive way to send anything, but it goes fast enough that high-value, perishable cargo is worth sending. The flower industry is a good example of this: flowers need to get to their destinations quickly and aren’t shipped in high volumes. Meanwhile, a load of iron can sit in a cargo hold for a weeks-long journey, and a ship will carry tens of thousands of tons.

ANALYSIS: Ultra-Efficient Aircraft Wins NASA Prize

In order for the Aeroscraft to be competitive, it would need to carry cargo that wasn’t perishable or didn’t need to be delivered immediately. That limits the market it can service

And even though it doesn’t need a fully equipped airport, future versions of the Aeroscraft able to carry hundreds of tons will be hundreds of yards long, necessitating a big, clear area. So shipping to city centers is less realistic.

Other companies have tried to make airships viable. Northrop-Grumman has developed an airship for surveillance for the U.S. Army. Meanwhile Cargolifter, a German company, tried to design and build an airship that could carry 176 tons. The company declared bankruptcy in 2002. Cargolifter sill exists, but it is selling a balloon-based crane system rather than a cargo-carrying dirigible. Lockheed-Martin designed and built a prototype for the Army as well, the same contract that Northrup-Grumman won. Now called the SkyTug, the rights to the design were taken over by a Canadian company, Aviation Capital Enterprises.

Jojo-Verge said Aeroscraft isn’t trying to compete directly with other modes of transport, but to address markets that are more difficult for trucks or planes. Remote areas is one of those — there are many places, he said, that have poor road connections and where an Aeroscraft carrying 66 tons would be more efficient than a truck picking its way through a remote trail. If anything, the Aeroscraft might just be in the “sweet spot” that other cargo methods don’t handle well.

In addition, Aeros plans to build bigger airships. “The thing is, our design gets more efficient as you get bigger,” Jojo-Verge said. A 200-ton Aeroscraft would not use much more fuel than the 66-ton version, and it would go just as fast.

And he sees disaster relief as a good initial market. “Imagine an earthquake in L.A.,” he said. “You could get one of these in anywhere in the city.” While it won’t ever be as cheap as a truck or train, it’s faster than a cargo ship. “We’re trying to fill a gap,” he said.

What evil lurks in the brain? German neurologist says he’s found a ‘dark patch’

After studying the brains of violent killers, rapists and robbers, German neurologist Gerhard Roth claims to have found a “dark patch” in the center of the brain — he calls it the evil spot, a genetic source of violent behavior.

Roth, a professor at the University of Bremen, told Germany news site that he had shown short films to criminals and measured their brain activity. A small section at the front of their brains showed no reaction to violent scenes; it remained “dark” when shown dark scenes.

“Whenever there were brutal and squalid scenes, the subjects showed no emotions. In the areas of the brain where we create compassion and sorrow, nothing happened,” Roth said.

BioEdge, a blog dedicated to bioethics news, translated Roth’s German into English: “This is definitely the region of the brain where evil is formed and where it lurks.”

Not so fast. Human behavior, affect and emotion is likely a far more intricate thing, explained Dr. Steven Galetta, chairman of the neurology department at the NYU School of Medicine.


‘It’s probably not as simple as X marks the spot for a particular behavior.’

“People look at the blood flow to one area and they say, ‘aha, this is the evil patch.’ It’s probably a lot more complex than that,” Galetta told

“Certain areas are likely important for certain behaviors, certain attitudes. But it’s probably not as simple as X marks the spot for a particular behavior.”

Roth’s study, according to, was conducted for the German government on violent convicted offenders. He said the dark mass that he has identified appears in all CT scans of people with such records — and taking it out ended their “evil” behavior.

Roth did not respond to requests for more details on his study.

Terre Constantine, executive director of the Brain Research Foundation and the former director of the Jack Miller Center for Peripheral Neuropathy, expressed skepticism at the report, but agreed that brain abnormalities such as tumors can affect behavior.

“It absolutely can affect the brain and your personality and how you communicate. And it can make you aggressive — not all tumors, of course: it depends where it is,” Constantine told

Her foundation, which funds research into neuroscience seeking to understand the brain’s workings, has aided research similar to Roth’s with more advanced imaging techniques.

One recent study from a University of Chicago researcher studied parenting behavior. It found activity in the amygdala — a portion of the brain connected to the limbic system — correlated to parenting style. It “lit up” in the brains of normal mothers, while “harsh parents” didn’t react to scenes of bad parenting.

“There’s clearly differences in the brain depending on what sort of disease or abnormality a person has,” she told And many things can cause abnormal behaviors. “They’re either wired differently or there might be some disease that’s causing the brain to atrophy.”

But Constantine agreed with Galetta: Complex topics and behaviors are likely linked to other areas of the brain, rather than concentrated in one “evil area.”

“I would argue it’s probably not the only “evil” spot,” she said. “There are other areas in the brain, there are lots of … empathy areas or violent areas or just social reaction areas within the brain.”

“This may be one of the spots, but I’d be surprised if it’s the spot.”
