NASA confirms ‘impossible’ thruster actually works, could revolutionize space travel

Filed under: Uncategorized — bferrari @ 11:56 am

“Impossible” microwave engine !

When Roger Shawyer first unveiled his EmDrive thruster back around 2003, the scientific community laughed at him. They said it was impossible, that it was based on a flawed concept, and couldn’t work because it goes against the laws of conservation of momentum. But somehow, despite all of the reasons it shouldn’t work, it does.

Scientists at NASA just confirmed it.

Shawyer’s engine provides thrust by “bouncing microwaves around in a closed chamber.” That’s it. There’s no need for a propellant of any kind like rocket fuel. When filled with resonating microwaves, the conical chamber of the thruster experiences a net thrust toward the wide end. These microwaves can be  generated using electricity, which can be provided by solar energy. In theory, this means that the thruster can work forever, or at least until its hardware fails.

Initially, the idea was met with criticism because it flies in the face of Newtonian physics, which dictate that no closed system can have this kind of net thrust. Shawyer, however, says that net thrust occurs because the microwaves have a group velocity that’s greater in one direction when Einstein’s relativity comes into play. But can it really?

Apparently, yes. The idea was first confirmed by a group of Chinese scientists back in 2009. They built their own version of Shawyer’s thruster and were able to produce 720 milinewtons of force — but even then, nobody really believed it.

Now, American scientists at NASA have given the EmDrive a go, and once again confirmed that it actually works. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio, and astonishingly enough, they are positive. The team behind the drive still doesn’t know why it works, just that it does.

“Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma,” the report reads.

Therefore, we’ve still got a long road ahead of us before we’ve got energy-harvesting, self-propelled intergalactic spacecraft, but these studies (assuming they’re not flawed) suggest we’ve made a major breakthrough in space propulsion systems. With further refinement, microwave thrusters could drastically cut the cost of satellites and space stations, and potentially even make it possible to travel to distant planets, like Mars, in weeks rather than months or years.

One Giant Screwup for Mankind

Stan Lebar

Stan Lebar

WHEN THE EAGLE LUNAR MODULE TOUCHED DOWN ON JULY 20, 1969, all eyes were on astronaut Neil Armstrong. But Stan Lebar’s ass was on the line.

A young electrical engineer at Westinghouse, Lebar had been tasked with developing a camera that could capture the most memorable moment of the 20th century – the Apollo 11 moon landing. The goal of the mission wasn’t merely to get a man on the moon. It was to send back a live television feed so that everyone could see it – particularly the Soviets, who had initiated the space race in 1957 by launching Sputnik. If the feed failed, Lebar, the designated spokesperson for the video setup, would turn the camera on himself at Mission Control in Houston and apologize to more than half a billion TV viewers. “It was my responsibility,” he says. “I’d have to stand up and take the hit.”

Building a camera that could survive the crushing g forces of liftoff and then function in near-weightlessness on the moon was only part of the challenge for Lebar. The portion of the broadcast spectrum traditionally used for video was sending vital ship data to Earth, and there was no room left for the standard black-and-white video format of the era: 525 scan lines of data at 30 frames per second, transmitted at 4.5 MHz. So Lebar helped devise a smaller “oddball format” – 320 scan lines at 10 fps, transmitted at a meager 500 kHz. Tracking stations back on Earth would take this so-called slow-scan footage, convert it for TV broadcast, and beam it to Mission Control, which would send it out for the world to see.

And that was the easy part. To ensure a direct transmission signal from the moon, NASA had to maintain stations in three continents – two in Australia (the Honeysuckle Creek Tracking Station near Canberra and the Parkes Radio Observatory surrounded by sheep paddocks west of Sydney); one at the Goldstone Deep Space Communications Complex in the Mojave Desert of California; and one at the Madrid Manned Flight Tracking Site in Spain. As Armstrong suited up for his first moonwalk, Dick Nafzger, the 28-year-old coordinator of the tracking stations’ TV operations, was as nervous as Lebar. Nafzger was the guy at Mission Control charged with monitoring ground equipment and the conversion of the slow-scan footage to US broadcast standards. “We were all going to be involved in something of monumental historic importance,” he says.

When Armstrong opened the hatch on the lunar module, stepped out onto the moon, and uttered his famous words about mankind’s giant leap, the tracking stations with a direct line on the Apollo‘s signal were the ones in Australia. The 200-foot-diameter radio dish at the Parkes facility managed to withstand freak 70 mph gusts of wind and successfully captured the footage, which was converted and relayed to Houston. “When the door opened, I knew the camera was working,” Lebar says, “It was pure elation.”

The world watched in awe as Armstrong took his first steps, and the camera engineers at Mission Control started popping the champagne corks. Amid the celebration, though, Lebar scrutinized the video, and his joy vanished. He had known the converted footage wouldn’t be as good as a standard TV signal. But as Armstrong bounded through the Sea of Tranquility, the astronaut looked like a fuzzy gray blob wading through an inkwell. “We knew what that image should look like,” Lebar says, “and what I saw was nothing like what I’d simulated. We looked at each other and said, ‘What happened?'”

With the rush of history upon him, Lebar let the concern pass. “As much as we may have found it disturbing,” he says, “the public didn’t seem to mind. Everyone seemed happy to see the guy on the moon.” Lebar never even saw the raw transmission; only the few tracking-station engineers did. But as they converted the feed for Mission Control and the worldwide audience, they also recorded it onto huge reels of magnetic tape that were promptly sent to NASA to be filed for safekeeping.

Not long ago, Lebar learned why the footage had looked like mush: The transfer and broadcast had degraded the image badly, like a third-generation photocopy. “What the world saw was some bastardized thing,” says Lebar, now 81. “Posterity deserves more than that.” Good thing the engineers in Australia recorded the raw feed. Now Lebar and a crew of seasoned space cowboys are trying to get that original footage and show it to the world.

There is just one problem: NASA has lost the tapes.

EVERY YEAR, NASA buffs and vets of the Apollo 11 mission reunite for a picnic near Canberra at the site of the Honeysuckle Creek station, which was shuttered in 1981. Seventy-year-old Bill Wood, an engineer at Goldstone during the moonwalk, describes the event as “a bunch of old guys in hard hats looking at an antenna while local TV follows us around.” Sometimes, talk turns to the effort to persuade the Australian government to erect a fitting commemorative on the site. But mostly, they just chat and show off old pictures and memorabilia.

During the 2002 reunion, one of the retirees produced a souvenir he had rediscovered in his garage: a 14-inch reel of magnetic tape from the Apollo era. They passed it around, marveling at how big and clunky it was, and then went back to their barbecue. The next year, a couple of Honeysuckle Creek vets showed up with keepsakes even more impressive: still photos they had snapped of the monitors in the station showing the moonwalk. The images displayed the original slow-scan footage, not the version converted for television.

“When we saw them, we realized they were significantly better than what had been seen in Houston,” says Colin Mackellar, a local minister and self-described space nut. He was only 12 during the Apollo 11 mission, but watching it on TV shaped his life. When he’s not tending his flock at Greystanes Anglican Church, he’s updating his Web site, honeysucklecreek.net, a tribute to the tracking station and the radio wonks he idolized.

Wood dug through his files and found an old Polaroid that showed the slow-scan footage as it appeared on a monitor at Goldstone. Like the Honeysuckle Creek photos, it was of a much higher quality than anyone had imagined. Curious and perplexed, he was determined to figure out whether the raw images of the moonwalk really were more crisp than what the world had seen in 1969.

Manufacturing Begins For Fusion Reactor Parts

Filed under: Uncategorized — bferrari @ 11:58 am

The first components of what will become the world’s largest experimental nuclear fusion reactor are now being manufactured around the world. Once it starts operating in 2020, the multinational ITER demonstration power plant will help scientists understand how to fuse hydrogen nuclei together to make energy, the same phenomenon that powers the sun.

At the heart of the project is the 25,400-ton tokamak, a machine that uses magnetic fields to confine a plasma that burns at 150 million degrees Celsius. The giant magnets used to corral the plasma are now being manufactured at a facility in La Spezia, Italy, as seen in the gifs above and video below.

 

Inside the plasma, hydrogen nuclei will slam together with enough force to turn some of their mass into energy. This demonstration of Einstein’s E=mc2 will produce a huge amount of energy from a small amount of matter—the U.S. ITER office says one gram of hydrogen fuel will generate as much power as eight tons of oil. The trick that still needs to be figured out is how to get more energy out of the fusion reaction than what needs to be put in to start it. Researchers are making significant strides toward that goal.

The project is being run cooperatively between Europe, the U.S., Russia, Japan, China, Korea and India. The tokamak is expected to generate 500 megawatts of power once it is running at full power. The first plasma is expected to be generated in 2020 and fusion might be seen in 2027.

Photos from the first spacecraft to rendezvous with a comet

Filed under: Asteroids, Comets — bferrari @ 4:04 pm

On Wednesday, for the first time ever, a human spacecraft made a controlled rendezvous with acomet. This is what it saw as it approached:

For generations of people raised on sci-fi movies, the video might not look like a huge deal. But it’s pretty amazing to realize that this choppy little clip is an actual image of a real comet — the most detailed look we’ve ever had.

The spacecraft is the European Space Agency’s Rosetta probe, and the comet is 67P/Churyumov–Gerasimenko, a roughly 2.5 mile-wide chunk of rock, dust, and ice that’s currently 250 million miles away from Earth, about halfway between the orbits of Mars and Jupiter.

The probe was launched in 2004 specifically to study this comet, and is now within about 62 miles of it. Rosetta traveled nearly 4 billion miles to get there, looping around Earth and Mars several times in order to use their gravity to add momentum to its flight path. 

Two previous probes have briefly flown by comets, but neither came nearly as close as Rosetta. Additionally, in 2005, NASA’s Deep Impact Probe was intentionally crashed into a comet to analyze its interior.

Rosetta, though, will be the first mission to study a comet close-up for an extended period of time. The plan is for the probe to begin orbiting the comet within the next six weeks and accompany it for about a year, deploying a small landing craft in mid-November to analyze soil and rock samples.

Scientists hope that measurements collected by Rosetta will help us learn more about the composition of comets in general. This sort of information could be quite relevant to understanding the formation of all planets, and even the development of life on Earth: comets formed during the earliest stages of the solar system, and some scientists believe that the water on Earth was originally delivered by comets and asteroids.

For an idea of how big this comet is, we bring you a nice image from the European Space Agency comparing it to some well-known buildings and mountains:

Space plane tech could power hypersonic aircraft for US military

Engine technology being developed for a British space plane could also find its way into hypersonic aircraft built by the U.S. military.

The U.S. Air Force Research Laboratory is studying hypersonic vehicles that would use the Synergetic Air-Breathing Rocket Engine (SABRE), which the English company Reaction Engines Ltd. is working on to power the Skylon space plane, AFRL officials said.

“AFRL is formulating plans to look at advanced vehicle concepts based on Reaction Engine’s heat-exchanger technology and SABRE engine concept,” officials with AFRL, which is based in Ohio, told Space.com via email last month. [The Skylon Space Plane (Images)]

A bold British space plane concept

SABRE and Skylon were invented by Alan Bond and his team of engineers at the Abingdon, England-based Reaction Engines.

SABRE burns hydrogen and oxygen. It acts like a jet engine in Earth’s thick lower atmosphere, taking in oxygen to combust with onboard liquid hydrogen. When SABRE reaches an altitude of 16 miles and five times the speed of sound (Mach 5), however, it switches over to Skylon’s onboard liquid oxygen tank to reach orbit. (Hypersonic flight is generally defined as anything that reaches at least Mach 5.)

Two SABREs will power the Skylon space plane — a privately funded, single-stage-to-orbit concept vehicle t-hat is 276 feet long. At takeoff, the plane will weigh about 303 tons.

The SABRE heat exchanger is also known as a pre-cooler. It will cool the air entering Skylon’s engines from more than 1,832 degrees Fahrenheit down to minus 238 degrees Fahrenheit in one one-hundredth of a second. The oxygen in the chilled air will become liquid in the process. [Skylon's Many Possible Missions (Video)]

“The [pre-cooler] performance has always been pretty much what we predicted,” Bond explained in an interview with Space.com at the Farnborough International Airshow in England on July 16. “We’ve now done over 700 actual tests. It’s now done as much service as a pre-cooler would in a real engine.”

Bond’s team has also successfully tested the pre-cooler for a problem aviation jet engines have to deal with: foreign objects being sucked in.

“We know it [the pre-cooler] can take debris, insects, leaves,” Bond said.

Working with the U.S. military

Bond estimates that the pre-cooler is now at a technology readiness level (TRL) of about 5. NASA and AFRL use a 1-to-9 TRL scale to describe a technology’s stage of development. According to NASA’s TRL descriptions, 5 represents “thorough testing” of a prototype in a “representative environment.”

The AFRL work is being carried out under a Cooperative Research and Development Agreement (CRADA) with Reaction Engines that was announced in January. AFRL officials told Space.com that they are using computers to model SABRE.

“The Air Force research laboratories in the States have carried out some modeling to verify that the SABRE does actually work, that it is a real engine, and so I am hoping they are going to confirm that very soon,” Bond said.

“This is obviously opening doors in the United States, and again, I can’t say a great deal about that, but we have very good dialogue going across the Atlantic,” he added. “In the next couple of years, it’s going to be quite exciting.”

Bond declined to confirm rumors of organized support within the U.S. aerospace community that involves former senior program managers of the U.S. military’s most high-profile defense projects.

Bond sees Skylon as an international project that would include the U.S. and Europe.

“We’re in dialogue with people across Europe in regard to supplying [rocket engine components]. We don’t want to reinvent the wheel; we’d like to be the engine integrator and put it on our test facilities and run it,” he explained.

Milestones approaching

Two SABRE engines are expected to be tested in 2019. “Hopefully, the earlier part of 2019,” Bond said. “I’d like to feel we can test them on Westcott. That is where the rocket propulsion establishment used to be.” (In the 1950s and 1960s, the United Kingdom had its own space program; the nation launched a satellite called Prospero with its last rocket, Black Arrow, in 1971. Westcott is about a one-hour drive from Reaction Engines’ headquarters).

The SABRE development program is expected to cost 360 million British pounds ($600 million at current exchange rates). “We’ve got 80 million [British pounds] of the 360 million lined up. We’re well on our way to that,” Bond said.

Of the 80 million pounds, 60 million is from the U.K. government. As with thecommercial ventures NASA supports, Reaction Engines has to meet milestones to acquire those government funds.

“We have to meet milestones, but those are programmatic issues,” Bond said. “There is nothing contentious about that; it is just a matter of getting the work done to get there. I think of it as an R&D program, and we’ve done the ‘R’ bit, and this part forward is the ‘D’ bit. We’ve spent years making sure the technology actually works.”

In January, this R&D program reached its third phase, which is split into four sections, known as 3A, 3B, 3C and 3D. Sections 3A and 3B are being carried out in cooperation with the European Space Agency (ESA).

Section 3A began in January and will last until April 2015. It involves the engine’s system design, revising the engine’s layout and studying the impact on Skylon’s performance. This work will cost 8 million euros ($10.7 million, or 6.4 million British pounds), half of which will come from the U.K. government and ESA and the other half from Reaction Engines’ private investment.

“This is it for real now; this isn’t studies anymore,” Bond said. Section 3A will continue until spring 2015, and section 3B is due to start in January 2015, he added. “That is the preliminary design phase,.” Bond said.”

Section 3B will last until the end of 2015. During this section, the characteristics of the engine components will be defined and technical specifications produced.

Section 3C, which starts from mid-2015, will see 10 million euros ($13.37 million, or 8 million British pounds) from the U.K. government spent. The section 3C work with suppliers overlaps section 3B. This is because some of the components will get specifications during 3B before other parts of the engine are fully defined. Those detailed components with specifications can then be given to prospective suppliers during the first few months of section 3C.

“In 3C, we start to do detailed design — what the bearings will look like, who is the supplier going to be, that sort of stuff. This is really exciting stuff. We’re starting to pull the real engine together during the course of next year,” Bond said.

He explained that for section 3C, his company will spend “some of the U.K. government money alongside some of our own private investment.” The government money has “enabled us to raise quite a few millions of private investment to go alongside that, and we’re continuing that [fund-raising] activity,” Bond said.

Message from a Space Traveller… Far Far in the Future…

Filed under: Cool, Extraterrestrial Life, Life, Religion — bferrari @ 7:01 am

 

I remember when we took our first steps upon the moon. For millennia we had looked upon her as a merciful goddess, who gifted us with light in the darkness and the rule to measure our years. What bounty of life did she hold, we wondered, when we discovered our world was a sphere? Then we invented telescopes, and found her to possess not an alien world of cold white fire, but the rough beauty of the highest, most barren mountains.

Even though our imaginations had failed us, we still sought to visit her, this great beautiful land that had occupied our nights and dreams since the dawn of our species. From swan-pulled boats to great hot-air balloons, we struggled to reach the land that we could never touch. Then came the wars, the terrible wars, and we found ourselves thrust out of our gentle lives. Great new weapons were forged, new realms of science uncovered. And the secret of spaceflight discovered.

When I finally reached her, after travelling for three days aboard my tiny rocket pod, I touched down in one of the great basalt seas that dotted the moon’s surface. And there, I found the first signs of life on the moon; a flag in brilliant colours, a ship much larger and more alien than my own and a bronze plaque bearing the image of a world and an unknown language.

When we tested the dust upon these artifacts, we came to a startling conclusion. They were more than four million years old, the product of a civilisation little more advanced than our own. The world on the plaque was unrecognisable except to paleogeologists, as the state of our continents and seas in the distant past, when our race had swum through primordial seas. Imagine! Some other life had lived and breathed and touched the heavens, and vanished, yet still its creations endured upon the merciful moon.

When we walked the rust-red surface of Geyes, we bore the inscription upon the plaque with us, engraved on our ships. When we sailed the endless skies of Jalbador, we bore the inscription on our atmosuits. When we launched our first interstellar spaceship, she bore the inscription upon her brow and carried the plaque upon her bridge. And when we first made contact, we learned what the inscription said.

“We came in peace, for all mankind.”

The European Space Agency says comet-chasing space probe Rosetta has reached its destination after a journey lasting more than a decade.

Scientists and spectators at ESA’s mission control in Darmstadt, Germany, cheered Wednesday after the spacecraft successfully completed its final thrust to swing alongside comet 67P/Churyumov-Gerasimenko.

ESA chief Jean-Jacques Dordain says the probe’s rendezvous with 67P is an important milestone in Rosetta’s life.

The goal of the mission is to orbit 67P from a distance of about 60 miles and observe the giant ball of dust and ice as it hurtles toward the sun. If all goes according to plan, Rosetta will drop the first ever lander onto a comet in November.

Scientists hope this will help them learn more about the origins of comets, stars and planets.

Meet the Starship Enterprise of the Sea

Filed under: Cool, Gadgets — bferrari @ 2:27 pm

 SeaOrbiter can carry a mix of scientists and crew members.

SeaOrbiter can carry a mix of scientists and crew members.

A French architect’s audacious plans for a ship that will change the ocean exploration is done.

Garnering comparisons to Star Trek’s starship Enterprise, the SeaOrbiter is the brainchild of French architect Jacques Rougerie. Set to begin construction this spring, the 190-foot-tall semisubmersible vessel will be the culmination of nearly 30 years of Rougerie’s research and development.

Six of the SeaOrbiter’s 12 floors are below sea level, allowing for uninterrupted underwater observation. Although the ship’s main mission is to research the biodiversity and climate of the sea, the real goal for Rougerie is to give the public a better understanding of how crucial the ocean is to Earth’s well-being.

Ninety-nine percent of the $50 million project was financed through the French government and private companies. To get people more involved, Rougerie is crowdfundingthe last 1 percent of the project. “The more humans understand about the underwater world, the more respect they will have for it,” he says. 

22 People: Number the SeaOrbiter can host. The ship will carry a mix of scientists and crew members. 

Quite a View: ‘We want people to appropriate the project to themselves,” says Rougerie. Which is why he raised money through KissKissBankBank, a French crowdsourcing website, to fund construction of the Eye of the SeaOrbiter. Equivalent to a ship’s crow’s nest, the Eye towers 60 feet above the surface. It serves as a lookout and houses a communications system that lets the crew send live broadcasts of life on board.

Hard at Work: Keeping busy won’t be a problem for the crew. The “modular lab” can be used as a laboratory for scientists as well as a fitness room equipped with treadmills. The lab also includes a medical zone. A certified doctor with basic surgery skills will be on board in the event of an emergency.

2,600 Tons Displacement: The overall weight of the ship. It is built from 500 tons of Sealium, a recyclable aluminum designed for marine environments.

A Life Aquatic: Given that voyages will last three to six months, there will be ample time to collect data and perform experiments. The underwater area, known as the hyperbaric lab, is equipped with an observation deck made of transparent polycarbonate panels, allowing for direct underwater observation. Because the conditions underwater are similar to those in space in terms of pressure and isolation, the SeaOrbiter will be used by NASA and ESA (the European equivalent) for protocol training as well as physiological and psychological experiments.

Go With the Flow: The SeaOrbiter was designed primarily to float along with the ocean’s natural currents, allowing scientists to study the relationship between those currents and climate. The keel weighs 180 tons and helps provide stability to the ship. It can be retracted when the vessel is in shallow water.

5 Ships: The total number of SeaOrbiters Rougerie eventually hopes to build, one to sail in each of Earth’s oceans. A number of partners have given their support to the SeaOrbiter project, including National Geographic and UNESCO.
