Comments Off on NASA plans to send a helicopter to Mars

A small, autonomous helicopter could soon soar above the rusty rocks of Mars . Dubbed the Mars Helicopter, the rotorcraft is hitching a ride to the Red Planet as part of NASA’s Mars 2020 rover mission. The BBC said this could be the first test of “heavier-than-air aircraft on another planet.” “After the Wright Brothers proved 117 years ago that powered, sustained, and controlled flight was possible here on Earth, another group of American pioneers may prove the same can be done on another world,” NASA’s Science Mission Directorate associate administrator Thomas Zurbuchen said . The technology demonstration has been many years in the making; it started in 2013 at NASA’s Jet Propulsion Laboratory (JPL). The Mars Helicopter weighs just under four pounds, with a fuselage about as big as a softball. It has twin, counter-rotating blades that will slice the air at nearly 3,000 revolutions per minute (rpm), which, according to NASA , is “about 10 times the rate of a helicopter on Earth.” Related: NASA unveils plan to make oxygen on Mars Solar cells will help the Mars Helicopter charge its lithium-ion batteries , and it’s equipped with a heating mechanism to survive frigid Martian nights. NASA is planning as many as five flights over a 30-day test campaign. The first flight could see the Mars Helicopter fly up to 10 feet and hover there for around 30 seconds. As it flies farther and longer in following tests, it could travel “up to a few hundred meters” and soar for around 90 seconds. JPL Mars Helicopter project manager Mimi Aung said in NASA’s statement, “The altitude record for a helicopter flying here on Earth is about 40,000 feet. The atmosphere of Mars is only one percent that of Earth, so when our helicopter is on the Martian surface, it’s already at the Earth equivalent of 100,000 feet up. To make it fly at that low atmospheric density, we had to scrutinize everything, make it as light as possible while being as strong and powerful as it can possibly be.” NASA describes the Mars Helicopter as a high-risk, high-reward project. The agency said in their statement if the technology demonstration doesn’t work, the Mars 2020 mission won’t be impacted — but if it does, “helicopters may have a real future as low-flying scouts and aerial vehicles to access locations not reachable by ground level.” + NASA Via the BBC Image via NASA/JPL-Caltech

Comments Off on AeroMobil reveals flying taxi that transforms from car to electric airplane

Designed for both the skies and the streets, the AeroMobil 5.0 is the latest futuristic creation from the Slovakia-based flying car company. Rather than taking off as a traditional airplane does, the AeroMobil 5.0 is able to gain altitude through vertical thrust from powerful rotors embedded in retractable wings that deploy when you are ready to hit the skies. A rear propeller provides the vehicle with midair thrust. Billed as the “first and only electric VTOL (Vertical Takeoff and Landing vehicle) to also drive on the road,” the AeroMobil 5.0 could potentially someday be your taxi, offering convenient flights right at your doorstep. The AeroMobil 5.0 is designed to complement previous models of flying car from the company, including the AeroMobil 4.0. “The multi-product strategy means we can provide urban travel with the AeroMobil 5.0 VTOL and intra-city travel with the AeroMobil 4.0 STOL,” said Juraj Vaculik, co-founder and CEO of AeroMobil, in a statement . “Our strategy solves the limitations of alternative VTOL concepts which are tied to dedicated landing pods rather than also using the existing road infrastructure .” Related: Uber and NASA team up to launch flying taxis by 2020 The AeroMobil 5.0 is designed to seat four passengers, with each rider having access to a personalized experience thanks to a sophisticated advanced data, communications and media system onboard. The cumulative experience at AeroMobil and developed technologies upon which the new flying car is based has made the company quite confident in its ability to finally deliver on that long-held dream of owning, or at least riding in, a flying car. “AeroMobil 4.0 STOL uses several patented technologies, a highly innovative combustion engine and has the benefit of using existing aerospace and automotive technology, combined in a unique way, thus achieving far greater energy efficiency , speed and range than any electric VTOL,” said AeroMobil Chairman Patrick Hessel in a statement . “It is also designed within existing regulation , hence enabling much sooner go-to-market in 2020 than the electric VTOL category, which in general is being mooted as ready for shipment in 2025”.

Comments Off on Uber and NASA team up to launch flying taxis by 2020

Although Uber has suffered some setbacks recently in Europe, having recently been banned from London’s streets , it seems to be clear skies in the United States for the ride-hailing/future self-driving car company. In a speech at the Web Summit in Lisbon, Portugal, Jeff Holden, head of product at Uber, announced that the company has signed a Space Act Agreement with NASA to design and enact an air traffic control system for its prospective flying taxi fleet as part of its Uber Elevate service. Uber hopes to get its taxis airborne by 2020, with three cities – Dallas-Fort Worth, Dubai, and now Los Angeles – serving as test sites. With its agreement to develop software with NASA, Uber has taken one step closer towards take-off. In a video shown at Uber’s NASA collaboration announcement, the public is offered a look into how Uber Elevate would function. Just as it is for its earthbound service, users would hail a cab using the app. After booking a flight , users would head towards a designated port, shown on top of a tall building in the video, where they would board their taxi. The video demonstrates the flying taxi’s traffic dodging ability by showing riders soaring over gridlock and highways-turned-parking-lots. The company claims that the flying taxi service could turn an hour and a half drive from LAX to the Staples Center in Los Angeles into a half hour pleasure cruise. “Closer than you think” is the tagline that concludes the video, hinting that the long-promised future featuring flying cars may finally be arriving. Related: Airbus’ flying electric taxi is on track to soar next year Uber’s flying taxis, and those of other companies hoping to get into the game, are known as vertical take-off and landing (VTOL) craft. By design, they are easier to land and take off because of their ability to hover in place. Uber is partnering with five companies, Aurora Flight Sciences, Pipistrel Aircraft, Embraer, Mooney and Bell Helicopter, to procure its vehicles, all of which will be electric . Uber is similarly partnering with ChargePoint to enable its vehicles to quickly recharge at vehicleports. Perhaps most ambitiously, Uber intends for its Elevate service to be priced similar to its UberX service. With credible collaborators in tow and a globally established brand, the sky seems to be the limit for Uber . Via Engadget Images via Uber

Groundbreaking quark fusion generates 10 time as much energy as nuclear fusion

Comments Off on Groundbreaking quark fusion generates 10 time as much energy as nuclear fusion

Physicists at Tel Aviv University and University of Chicago have discovered that quark fusion, involving the tiny particles known as quarks of which protons and neutrons are made, is an even more potentially energy-packed reaction than much-touted nuclear fusion . Although the scientists were originally concerned about quark fusion’s potential destructive power and had considered keeping the discovery secret, they came to learn that the process, still theoretical, would most likely be safe for civilian use. The newly identified kind of reaction, which could yield up to ten times as much energy as nuclear fusion, could be the answer to endless clean energy someday. A fusion reaction, whether nuclear or quark, occurs when two or more atomic nuclei are close enough to each other to form at least one different atomic nuclei and subatomic particles. In fusing, the involved reactants and products release an enormous amount of energy, which could theoretically be harvested as nearly-infinite clean energy , the holy grail of renewable technology. A quark reaction, which could yield up to ten times as much energy as nuclear fusion, involves the fusion of bottom quarks, subsequently resulting in a larger subatomic particle, a spare particle known as a nucleon, and an enormous output of energy.  It’s reaction is so potent that it is potentially more powerful than the reaction at the center of an exploding hydrogen bomb. Related: These mini spherical reactors could help scale fusion energy by 2030 “I must admit that when I first realized that such a reaction was possible, I was scared,” said Marek Karliner, quark fusion co-researcher at Tel Aviv University, “but, luckily, it is a one-trick pony.” Nuclear explosions in hydrogen bombs gain their destructive power from chain reactions. Quark fusion, it seems, could not possibly be dangerous because bottom quarks disappear only a picosecond (1/1,000,000,000,000 of a second) after they form. There simply is not enough time for these subatomic particles to form a chain reaction. “If I thought for a microsecond that this had any military applications , I would not have published it,” Karliner said, according to Live Science. Although quark fusion remains in the theoretical stage, the researchers state that it could be achieved at the Large Haldron Collider, the world’s largest and most powerful particle collider located in France .

Comments Off on Undergrad student leads scientists to discover nearly 100 unknown volcanoes – in Antarctica

There’s a new contender for the continent with Earth’s biggest volcanic region: Antarctica . Researchers found 91 previously unknown, massive volcanoes , ranging in height from around 328 to 12,631 feet. A University of Edinburgh third-year undergraduate student tipped the researchers off to the incredible discovery. Third-year student Max Van Wyk de Vries had the idea to analyze radar mapping data of the continent, and proposed a study to the university. Scientists were then able to verify there are indeed many volcanoes, concentrated in a region called the West Antarctic Rift System, and concealed by West Antarctica’s ice sheet. They say the newly discovered volcanic region is quite similar to East Africa’s volcanic ridge, which currently holds the title for the region with the world’s densest concentration of volcanoes. Related: Colossal landforms discovered under Antarctic ice sheet are 5X bigger than any on Earth Scientists drew on ice-penetrating radar measurements, satellite records, and geological information from aerial surveys to confirm Van Wyk de Vries’ concept. Van Wyk de Vries said in a statement, “Antarctica remains among the least studied areas of the globe, and as a young scientist I was excited to learn about something new and not well understood. After examining data on West Antarctica , I began discovering traces of volcanism. Naturally, I looked into it further, which led to this discovery of almost 100 volcanoes under the ice sheet .” Researchers say the discovery could help them better understand how Antarctica has changed during the varying climates of history, and how volcanoes influence ice sheet fluctuations. They have not determined if the volcanoes are active or not, but the awareness of their presence could help scientists researching seismic monitoring in Antarctica. The research has been published in the Geological Society Special Publications series.

Comments Off on Chinese researchers develop flexible salt-powered batteries

As the world rushes to transition to a new energy economy, researchers are uncovering novel methods to harvest energy from mundane, everyday sources. A research team in China has created a new battery that could be safely used in wearable or implantable devices, thanks to its use of salt-based electrolytes. This breakthrough could drastically improve the quality and safety of battery-dependent medical technology and may even pave the way for sweat-powered devices. In order to be effective, implantable or wearable batteries need to be flexible to allow functional bending on organic surfaces. In prior iterations, these batteries usually included a mix of toxic chemicals that serve as the electrolytes through which electrical charge can flow. This new battery uses non-harmful electrolytes such as sodium sulfate and saline. Because there is less of a concern regarding leakage of these chemicals, the battery’s design does not require extra material to protect humans from exposure and is significantly less bulky. Related: Inexpensive new battery generates power with just a drop of saliva One particularly interesting implication of a salt-based battery is the idea that the batteries could prove effective at harvesting sweat and other salty bodily fluids to power a workout assistant device. The researchers also noted that the batteries have a marked ability to convert dissolved oxygen into hydroxide ions, which could prove useful in medical applications.  “We can implant these fiber-shaped electrodes into the human body to consume essential oxygen, especially for areas that are difficult for injectable drugs to reach,” said researcher Yonggang Wang. “Deoxygenation might even wipe out cancerous cells or pathogenic bacteria since they are very sensitive to changes in living environment pH. Of course, this is hypothetical right now, but we hope to investigate further with biologists and medical scientists.” Via Engadget Images via Deposit Photos , Tim Simpson/Flickr  and Andy Armstrong/Flickr

Before long, passengers will be able to travel at airline speeds for the price of a bus ticket to destinations around the world. How so? By boarding the Hyperloop One, which uses magnetic levitation technology to transport objects in a vacuum. The concept, which was first proposed by Elon Musk in 2013, is finally becoming a reality – today Hyperloop One announced that it has completed its first full-scale test. The company’s hyperloop vehicle reached 70 mph while pulling 2Gs on the test track. The Verge reports that the aerodynamic pod is 28 feet long and is made of structural aluminum and carbon fiber. It relies on electromagnetic propulsion and mag-lev technology to carry both human and cargo passengers at near supersonic speeds. The company wrote on its website , “The world is ready for a new mode of transportation that will change the way we live. We’re in the business of selling time, the most precious resource there is.” After Hyperloop One’s first full system test, co-founder Shervin Pishevar and chief engineer Josh Giegel appeared on CBS This Morning. A video of the low-speed test was also released to the public (above). Pishever described the test as the company’s “Kitty Hawk Moment” and said it is their “first in flight ” milestone. Related: Hyperloop One exhibits exciting first images of full-scale test track Hyperloop One is now entering its next phase of testing with a goal of reaching 250 mph.

Comments Off on First civilian jetpack gives humans the power of flight

Most of us have dreamed about flying . Now company JetPack Aviation is making those dreams reality. They’ve designed “the only true JetPack ,” the JB10, and it packs a powerful punch. Humans can soar up to 10,000 feet in the air at speeds of 68 miles per hour with the futuristic technology . JetPack Aviation has designed a personal flight jetpack that allows humans to zoom through the air for around 10 minutes. The technology is powered by two efficient jet engines that run on diesel. While flying, users can lean forward to move and speed up, or lean back to slow down to a hover. The right handle controls thrust and throttle; the left handle governs spin. The jetpack can even be equipped with an automatic inflation system which will release a float bag in seconds if the jetpack hits water. Related: Dubai firefighters now have jetpacks in their arsenal JetPack Aviation CEO David Mayman said in a Mashable video, “I think that the jetpack is the ultimate expression of freedom. It’s more than just a fantasy or a dream; it’s more than science fiction ; it’s something that we can literally do right now.” Mayman has been working for ten years with chief designer Nelson Tyler, who has been working on jetpacks for decades and whom Mayman describes as “like one of the original Wright brothers.” The jetpacks aren’t just for having fun in the backyard; the company has envisioned several practical applications for their jetpacks as well. They said commuters and first responders could benefit from the technology, and the military could use the jetpacks on search and rescue missions. JetPack Aviation recently raised $285,269 on equity crowdfunding platform StartEngine . The company says 500 people, military services, and government agencies have contacted them for more information, and they’ve already received their first order from a private citizen.
