Amazon: Our Drones 'Will be More Like Horses Than Cars'

As reported by The VergeAmazon's delivery drones will be "more like horses than cars," according to Paul Misener, Amazon's vice president for global public policy. Misener makes the claim in an interview with Yahoo, but he doesn't mean that his company's aerial vehicles will be covered in fur and burdened with a love for sugar — instead, he likens them to horses because they'll automatically avoid obstacles that could be a danger to them.
"Try riding a horse into a tree."
"If you have a small tree in your front yard," Misener explains, "and you want to bang your car into it for some reason, you can do that. Your spouse might not be happy with you, but you can do it. But try riding a horse into the tree. It won't do it. The horse will see the tree and go around it. Same way our drones will not run into trees, because they will know not to run into it." Misener says Amazon's prototype drones have "sense-and-avoid" technology that aims to keep them out of power lines, trees, and other obstacles that could come between them and your ordered items.
That's prototypes, plural. Amazon is working on several variations of drone at the same time, Misener says, and is likely to use different drones when the time comes to actually roll the service out for customers in different locations. "Our customers in the United States live in hot, dry, dusty areas like Phoenix," he says, "but they also live in hot, wet, rainy environments like Orlando, or up in the Colorado Rockies." Their homes, too, are different. "Some live in rural farmhouses, some live in high-rise city skyscrapers, and then everything in between, in suburban and exurban environments." Those that live in larger homes with yards can expect deliveries dropped off there if they're not home when the drone calls, but Misener says Amazon is still working on how to get you your items if you live in an apartment building.
Amazon isn't worried about people shooting drones to get their items
Some have expressed concern that the sight of a drone carrying an Amazon package would entice people along its flight path to break out a rifle and try to shoot it down, but Misener dismisses the fears. "I suppose they could shoot at trucks, too," he says, glossing over the fact that trucks — unlike drones — have human drivers that might not take kindly to being shot at. But he says that Amazon thinks its Prime Air drones will be "as normal as seeing a delivery truck driving down the street someday," reducing the novelty and stopping would-be shooters from intercepting your orders.
More of an immediate concern is the legislation stopping Amazon's drones from getting off the ground. Amazon has proposed a limit that would keep piloted aircraft above 500 feet, while leaving a window from 200 to 400 feet that would allow its Prime Air drone fleet to operate, but the government body has been dragging its feet so far. "We believe that [the FAA] must begin, in earnest, planning for the rules that are more sophisticated, that go to the kinds of operations that Amazon Prime Air will encompass," Misener says. "Other countries already are doing this," he explains. "There's no reason why the United States must be first. We hope it is."

SpaceX Successfully Launches Satellite But Rocket Explodes During Drone Ship Landing Attempt

As reported by ForbesSpaceX successfully launched the Jason-3 satellite into orbit yesterday. However, its attempted landing of the rocket on a drone ship once again failed explosively.
Apart from the landing, the launch from a SpaceX Falcon 9 rocket from the Kennedy Space Center was flawless. It lifted off at 1:42pm ET from Vandenberg Air Force Base in California.
The Jason-3 satellite is a project of NOAA, in partnership with the Centre National d’Etudes Spatiales (CNES), European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), and NASA. Jason-3 continues a series of satellite observations of the ocean which began in 1992. The purpose of the satellite is to measure changes in the ocean’s surface. This helps scientists track sea level rise due to climate change.
In addition to tracking sea level rise, the satellite will also make possible better weather forecasting, including better tracking of hurricane intensity and changes of weather patterns caused by El Nino. It will also track decadal patterns in oceans that can be used to assist the management of fisheries and other ocean-dependent businesses.
The second part of SpaceX’s goal for this launch was to once again make an attempt to land a reusable Falcon 9 first stage onto the deck of a droneship on the ocean. In December, SpaceX was successful in landing a reusable first stage on the ground following a launch. However, it’s attempts to land on a ship so far haven’t worked.  Elon Musk's video of the landing is shown here.
Yesterday was no different, although the first stage came closer than ever. According to the company, the rocket made a successful soft landing on the ship about 1.3 meters from its target. However, one of the landing legs failed, causing the rocket to fall over and explode.

NASA Picks Three Private Space Companies to Resupply the ISS

As reported by EngadgetNASA will fund the International Space Station at least through 2024, so keeping the astronauts on it fed and experimenting is a big deal. That's why the nation's top space agency announced new resupply contracts for Orbital ATK and Elon Musk's SpaceX, two major incumbents that were joined by newcomer Sierra Nevada and its resumable, mini-spaceplane. Each company will get at least six resupply missions, but it's "likely" that NASA will buy more than 18 flights — NASA will grant additional missions based on what they and the station's spacefaring crew need at the time.

Speaking of needs, these three companies were chosen in part for their different approaches to transport. Orbital ATK (which used to be known as Orbital Sciences) has its non-recoverable Cygnus capsule, which typically houses waste from the Space Station and burns up in the atmosphere upon re-entry. SpaceX's Dragon capsule can be used to both ferry cargo to the station and bring things back down, though the capsule has to be fished out of the ocean. Then there's Sierra Nevada, whose Dream Chaser shuttle can land on traditional runways — that means samples returning to earth can be offloaded and studied that much sooner. Recovery of cargo could take as little as three hours, though that all depends on whether the Dream Chaser passes its test flights later this year.

US Government Announces $4 Billion Self-Driving Car Program

As reported by EngadgetTurns out we're way closer to our self-driving car future than most of us expected. US Department of Transportation Secretary Anthony Foxx announced at the Detroit Auto Show (pdf) Thursday that the Obama administration will have a national blueprint for autonomous vehicle standards by July. What's more the administration is earmarking $4 billion of the 2017 budget to create a decade-long program that will support and accelerate development of the technology.

"We are on the cusp of a new era in automotive technology with enormous potential to save lives, reduce greenhouse gas emissions, and transform mobility for the American people," Secretary Foxx said in a statement.

Currently, each state has individual laws regarding the burgeoning technology. This forces automakers and early adopters like Google to juggle multiple sets of rules and regulations, depending on where in the country the technology is being built. For example, California recently decided that a human "driver" be present at all times should something go wrong. This program should reduce the number of hoops companies have to jump through by creating an overarching, national-level development framework.

DARPA is Developing an Unjammable Communications System

As reported by Engadget: Electronic warfare (EW) techniques -- from killing missiles with microwaves to downing drones with radio interference -- have become an integral part of modern wars. 

This issue is exasperated by the fact that both sides in a conflict must also compete for the finite spread of interference-free wireless spectrum with which they operate their multitude of wireless devices. 

To maintain American fighting superiority over the likes of China and Russia, both of whom are considered "near peers" in terms of EW combat capabilities, DARPA has developed an ultrafast chip to convert analog wireless signals into digital ones in record time.

DARPA's ADC, or analog-to-digital converter, will allow US forces to avoid being jammed by enemy EW methods by processing chunks of the electromagnetic spectrum about 10 times faster than what current-generation alternatives can muster. It takes over 60 billion analog and digital samples -- equivalent to roughly 1 Terabyte of data -- every second. This allows US forces to analyze more data from a larger swath of the spectrum in the same amount of time as current ADCs.

The chip isn't quite ready for the battlefield just yet, however. Its current iteration still draws far too much power to be useful in the field. DARPA is therefore partnering with GlobalFoundries to shrink the processor from its current 32nm fab down to 14nm. That should reduce its power consumption by 50 percent while maintaining its blistering performance. Next, DARPA will tackle managing the massive amounts of data this thing produces.

Pilots Rely Too Much on Automated Tech, DOT Says

As reported by Engadget: While automakers are still in the midst of developing driverless tech for cars, pilots are already relying too much on automated systems. According to the Department of Transportation, the Federal Aviation Administration isn't even making sure they're properly trained on how to manually fly planes. 

In the audit report published by the agency, it said that "several recent accidents, including the July 2013 crash of Asiana Airlines flight 214" can prove that. Those instances showed that pilots who typically rely on automation can be prone to errors during emergency situations and in any event wherein they have to switch to manual controls.

The report continued:
"As a result, reliance on automation is a growing concern among industry experts, who have also questioned whether pilots are provided enough training and experience to maintain manual flying proficiency."

Advancements in technology contribute to "diminished manual flying skills," the DOT said, which is dangerous as studies show pilots overestimate their ability to navigate a plane in manual mode. To ensure the safety of passengers, the agency wants the FAA to develop guidelines airlines can use to train and evaluate their pilots. Plus, it believes the FAA should conjure up standards on how to determine if they've received sufficient training to be able to fly planes on their own.

Google Maps Will Soon Work Out Where You’re Going by Itself

As reported by The VergeGoogle is adding a new feature to Maps for Android that could make its navigation software even smarter. Called "Driving Mode," the new Maps mode will take into account your history and current location to try and determine your destination. The app will then suggest info about your route like travel times and traffic conditions, according to Android Police. It appears to be similar to the algorithmic suggestions offered up in Google Now cards, yet tailored for getting around by car and even when you already know how to get there. You'll be able to launch Driving Mode with an app icon shortcut or through Maps' in-app sidebar.
Image result for Google Maps Will Soon Work Out Where You’re Going by ItselfGoogle Maps version 9.19, the one with Driving Mode, is in the process of being pushed to the Play Store and may not be widely available for some time. You can install the version manually, but figuring out how to activate the feature is proving difficult. Android Police managed to get it up and running on two devices without figuring out how to replicate the process on a third. While we can hope Google's general release will fix the issue, we might be waiting until a later version to try out the fully featured Driving Mode.
