New Experimental Lockheed Supersonic Jet Starts Production (wtop.com)
Lockheed Martin's X-59 Quiet Supersonic Technology aircraft is officially in "the manufacturing phase," bringing the company "one step closer to enabling supersonic travel for passengers around the world." The experimental jet was awarded a contract from NASA earlier this year as it is capable of flying at supersonic speeds without creating loud supersonic booms. Currently, commercial supersonic aircraft are banned from flying over land because of the noise and potential damage the booms may cause. WTOP reports: "The long, slender design of the aircraft is the key to achieving a low sonic boom," said Peter Iosifidis, Low Boom Flight Demonstrator program manager at Lockheed Martin. "As we enter into the manufacturing phase, the aircraft structure begins to take shape, bringing us one step closer to enabling supersonic travel for passengers around the world," he said.
Lockheed expects to conduct its first flight in 2021 and gather community response data on the acceptability of the "quiet sonic boom" the plane creates. NASA will use that information to establish an acceptable commercial supersonic noise standard to overturn current regulations banning supersonic travel over land. The X-59 will cruise at a speed of about 940 mph and an altitude of 55,000 feet. Lockheed says it will create a sound about as loud as a car door closing, instead of a deafening sonic boom. -
National Microbiome Initiative To Harness Microbes For Health, Environment (wtop.com)
An anonymous reader quotes a report from WTOP: The National Microbiome Initiative being announced by White House science officials Friday aims to bring together scientists who study the microbes that live in the human gut and in the oceans, in farm soil and in hospitals -- to speed discoveries that could bring big payoffs. Consider: Taking antibiotics alters the diversity of your gut bacteria, which eventually settle into a new normal. The 2010 oil spill altered microbes in the Gulf of Mexico, which likewise settled into a new normal, said Dr. Jo Handelsman, associate director of the White House Office of Science and Technology Policy. Despite the parallels, "we have no idea if that's a healthier norm or a less healthy norm than before, and no idea how to fix it," said Handelsman, who led development of the initiative. The U.S. government spends about $300 million a year on microbiome research, until now mostly an effort to catalog different communities of bacteria, viruses and other microbes, Handelsman said. The National Microbiome Initiative will add $121 million this year and next for ecosystem-crossing federal research. And in partnership with the government, dozens of universities, foundations and other organizations are announcing more than $400 million in additional microbiome research investments, she said. The ultimate goal is to control and alter microbes to improve either human or environmental health. One of the most recent discoveries was of a gut microbe that completely lacks mitochondria. -
D.C. Police Detonate Man's 'Suspicious' Pressure Cooker
An anonymous reader writes: Yesterday evening in Washington D.C., police officers on routine patrol spotted an unoccupied car parked near the National Mall. They deemed it "suspicious," and took a look inside, where they found a pressure cooker. They also claimed to smell gasoline. The officers called the bomb squad, and at 7:45pm they initiated a controlled detonation of the car's contents. Afterward, a search of the car found no evidence that it contained explosives or any other hazardous materials. The car's owner was located and arrested for driving on a revoked license. -
Virginia DMV Cracks Down On Uber, Lyft
An anonymous reader writes 'Talk about regulatory capture! As radio station WTOP reports, "The Virginia Department of Motor Vehicles says that ride services Lyft and Uber are violating state law and must stop operating immediately. The DMV sent cease and desist orders to both companies Thursday." Who benefits most? It's not the people who are voting with their dollars and feet — seems more like the current stable of taxi drivers and others blessed by the state of Virginia. Good thing there's no call for or benefit from greater per-car occupancy, or experimentation more generally with disruptive disintermediation. Given enough bribe money down the road, I'm sure a deal can be struck, though.' -
Sochi Drones Are Shooting the Olympics, Not Terrorists
Hugh Pickens DOT Com writes "Rachel Feltman reports that drones are being used to film ski and snowboarding events at the Winter Olympics in Sochi and unlike military drones, which often look like a remote-controlled airplane, the creature floating around Sochi resembles a huge flying spider. The legs of the flying spider hold the rotors that spin around to keep it airborne. The drone then has a flight deck that holds the flight control system with GPS for navigation, sensors and receivers. The camera can be mounted in the middle or suspended below the flight deck. A drone with mounted camera can cost anywhere from a few thousand dollars to $37,000 for a top-of-the-line Ikarus from Britain's Heliguy, which is advising broadcast clients in Sochi on using drones. That compares with the cost of a few thousand dollars an hour to rent a helicopter with pilot, not including the camera crew and equipment. Cameraman Remo Masina says he can fly a drone at up to 40 mph while transmitting a high-definition, live image and says the chances of drone crashes are close to zero when a drone is handled by an experienced pilot, because the drones are programmed to return to base at the slightest problem — such as a low battery, rough winds or a malfunction. 'There have been mishaps, however. In one case last year, a drone filming an imitation version of Spain's running of the bulls in Virginia crashed and injured a few spectators.'" -
Cameras To Watch Cameras In Maryland
Cornwallis writes in with a story reminding cameras everywhere that just because you're paranoid doesn't mean they aren't watching you. "Many people find speed cameras frustrating, and some in the region are taking their rage out on the cameras themselves. But now there's a new solution: cameras to watch the cameras. One is already in place, and Prince George's County Police Maj. Robert V. Liberati hopes to have up to a dozen more before the end of the year. 'It's not worth going to jail over a $40 ticket or an arson or destruction of property charge,' says Liberati." -
VA Governor Wants Military Drones For Police
New submitter Screen404-O writes "During a radio interview, Virginia governor Bob McDonnell suggested that using unmanned drones to assist police would be 'great' and 'the right thing to do.' 'Increased safety and reduced manpower are among the reasons the U.S. military and intelligence community use drones on the battlefield, which is why it should be considered in Virginia, he says. ... McDonnell added Tuesday it will prove important to ensure the state maintains Americans' civil liberties, such as privacy, if it adds drones to its law enforcement arsenal.' Is this the next step toward militarizing our law enforcement agencies? How exactly can they ensure our privacy, when even the Air Force can't?" -
What NASA Won't Tell You About Air Safety
rabble writes "According to a report out of Washington, NASA wants to avoid telling you about how unsafe you are when you fly. According to the article, when an $8.5M safety study of about 24,000 pilots indicated an alarming number of near collisions and runway incidents, NASA refused to release the results. The article quotes one congressman as saying 'There is a faint odor about it all.' A friend of mine who is a general aviation pilot responded to the article by saying 'It's scary but no surprise to those of us who fly.'"
