Watch This Tesla Car Drive Itself With the New ‘Summon’ Option

As reported by The Next Web: Ok, this is cool. The latest version of Tesla’s software actually allows drivers to get out of the car and let the Model S do all of the work, driving itself with just a tap of the key fob.

Called ‘Summon,’ the feature allows Tesla owners to let the car park and back itself out of parking spaces at will. If the car is connected to a garage door through the ‘HomeLink’ connection, the car will also be able to operate that all by itself. So if you’re really over driving the extra few feet inside your garage or you’d just rather have your car ready to go in the morning, the Model S uses the myriad of sensors and cameras already built into the car to get the job done with no driver involved.

Plus, it just looks cool. Like James Bond cool.

The new update, v. 7.1, also features new restrictions to the car’s semi-autonomous ‘Autopilot’ feature to maximize road safety — particularly ensuring that the car does not exceed five miles above a given speed limit, and that the person operating the car must be in the driver’s seat. For those of you brave enough to take your hands off the wheel, you can do so with more safety involved.

Laser X-rays to Help Nab Nuclear Smugglers

As reported by GizMag: With over 100 million cargo containers in transit each year, screening them for illicit nuclear material is a major problem. To keep commerce flowing while maintaining an eye on nuclear terrorism and smuggling, a team of scientists at the University of Nebraska-Lincoln (UNL) is developing a laser-based X-ray machine that can image a uranium disk the size of a stack of three US nickels hidden between three-inch (7.6 cm) steel panels.

Nuclear smuggling is a much larger problem than many people realize. It isn't just a question of preventing the doomsday scenario of a terrorist group trying to sneak a nuclear warhead or dirty bomb past customs. There's also the matter of stopping the smuggling or theft of civilian nuclear materials for engineering or medicine that could fall into the wrong hands or endanger the public through improper disposal.

The problem is that equipment for routine scanning is expensive and tends to be on the bulky side, with some systems running to dimensions equivalent to those of a small stadium. This is not helped by the fact that detecting radioactive material is even more difficult if it's sealed in a shielded container.

The UNL team led by Donald Umstadter, director of the Diocles Extreme Light Laboratory at UNL, is working on a nuclear material imager that uses a laser-driven X-ray source based on the laser-wakefield-accelerator-driven inverse-Compton-scattering (LWFA-ICS) device. Put very simply, this is a device developed by UNL in 2013 that scatters lasers off of an electron beam generated by a synchrotron accelerator. In the UNL imager, this scattering produces a narrowly focused X-ray beam that can be directed like a laser pointer and can travel long distances.

According to UNL, the new imager reduces the size of stadium-sized facilities to that of a trailer truck. It's lighter, more portable, and uses lower energy levels, so it's safer to use with people in the vicinity. In proof-of-principle experiments, it imaged a coin-size sample and the teams says that it can detect uranium in smaller amounts than the required one-kilogram (2.2 lb) standard through steel much thicker than that used in shipping containers.

The UNL team is currently working on improving the performance and precision of the device, so it can identify shielded nuclear materials while the US government reviews the technology. The team sees the device as having applications in not only curtailing the smuggling of nuclear materials, but also in physics research and as a nuclear site inspection tool.

"It's not unusual for scientists to go beyond basic research to develop new technologies, as we did with our device," says Umstadter. "However, the great urgency and importance of detecting smuggled nuclear materials compelled us to go even further and be the first to apply the new technology."

This Drone Can Fly Through the Air and Under Water

As reported by TNW News: While drones have been getting a bad rap for dropping from the skies at inopportune moments, a new drone from Rutgers University can swim as well as fly.

Recently a World championship skier was nearly hit by a falling
drone during the World Cup in Italy.

Funded by a grant from the Office of Naval Research, the Naviator can be deployed for either aerial reconnaissance or for snooping underwater.

“They have submarines that can launch things from the submarine and it pops out into the water and goes and does some things, but it can’t come back,” explains Marco Maia, a Rutgers doctoral student who worked on the project.

“It does one mission and one mission only. Then you have airplanes that deploy vehicles from the air that can dive into the water, from then on they’re in the water and cannot come back out. This vehicle does all those things.”

The Office of Naval Research has taken a keen interest in the project as it can help with the maintenance of ships, explains associate professor Javier Diez.

“They have a number of applications we’ve been talking about. You can do ship inspections. You can deploy from the bridge and quickly be able to make the decision on whether to call a repairman or not. If you have an oil spill you can use this to see how far and how deep the spill goes.”

The naviator is just a concept for now. But the team from Rutgers are looking to improve speed and its ability to carry bigger payloads.

SpaceX Makes History: Successfully Launches, Lands Falcon 9 Rocket

As reported by NBC News: SpaceX successfully launched a Falcon 9 rocket on Monday night, the first from the private spaceflight company since its rocket exploded on liftoff in June.

The first stage of the rocket, used to propel the payload to 100km (62 miles) or so until the second stage takes over, then successfully landed on Earth again at a prepared landing zone. This is the first time SpaceX has ever attempted to land a rocket on land, and the first successful attempt to recover a rocket from an orbital flight. Previous attempts, all unsuccessful, were attempted on floating landing pads.

SpaceX has come close to landing a rocket but until now, never actually pulled the feat off. Blue Origin, founded by Amazon CEO Jeff Bezos, stuck a landing last month — but SpaceX founder Elon Musk pointed out that was a suborbital trip, the requirements for which are considerably different. Creating reusable rockets is important for lowering the cost of space travel, which could make space tourism and a trip to Mars more feasible.

The launch's payload, 11 ORBCOMM satellites destined to join others in the communications company's network, was also successfully deployed with no problems.

On June 28, a SpaceX Falcon 9 rocket carrying a Dragon spacecraft filled with cargo for the International Space Station exploded a few minutes after lift-off.

The launch was originally scheduled for Sunday night, but was delayed because there was a 10 percent better chance of a successful landing on Monday, according to Musk.

 

Below is a shot which showcases the scale of the concrete landing pad where the rocket booster landed. That’s a person standing right there in the middle in case you couldn’t tell.  
But on to the good stuff. Here we have a long exposure shot showcasing the rocket launch, re-entry, and landing burns.

Next we have a nice still of the first stage landing right before making impact. 

 

And of course, here’s the booster resting comfortably after a successful landing. 

 

Driverless Cars Always Obey the Law—Why That Could be a Problem

As reported by Business Insider: Earlier in November, Google got some interesting press when one of its cars was pulled over for, of all things, driving too slowly.  

But the incident shined a spotlight on a very real issue with driverless cars: they're too safe, and that simply doesn't mesh with the way humans drive.

The fact of the matter is humans don't obey traffic laws all the time — sometimes we zip through yellow lights or commit a rolling stop at stop signs.

 But when you combine human error with the consistent precision of driverless cars, accidents are inevitable.

That's why programmers are currently debating whether it's time to teach self-driving cars to commit infractions, according to a Bloomberg article.

“It’s a constant debate inside our group,” Raj Rajkumar, co-director of the General Motors-Carnegie Mellon Autonomous Driving Collaborative Research Lab in Pittsburgh, told Bloomberg. “And we have basically decided to stick to the speed limit. But when you go out and drive the speed limit on the highway, pretty much everybody on the road is just zipping past you. And I would be one of those people.”

When Rajkumar offered rides to members of Congress in the lab's driverless Cadillac SRX SUV, the car ended up swinging across three lanes of traffic to merge on I-395 because it didn't know how humans make room when there's a lot of traffic build up.

Although a human took control, thereby avoiding a potential accident, it showed how driverless cars struggle to interpret how humans drive.

“It’s a dilemma that needs to be addressed,” Rajkumar said.

The cop who pulled over the robot Google car that was driving too slow at 24 miles per hour in a 35 mile per hour zone also noted the issue with driverless cars being too cautious.

"“The right thing would have been for this car to pull over, let the traffic go and then pull back on the roadway,” Sergeant Saul Jaeger, the Mountain View cop, told Bloomberg. “I like it when people err on the side of caution. But can something be too cautious? Yeah.”

To address the issue, Google is working on making its cars more aggressive to "naturally fit into the traffic flow," Dmitri Dolgov, principal engineer of the program, told Bloomberg.

“Driving is a social game," he said.

Galileo Program Adds Pair of Satellites to GNSS (EU GPS) Constellation

As reported by The Register: Two new satellites blast off, eight now in orbit.

Europe is now two satellites closer to firing up its Galileo SatNav system following the launch of Galileos 11 and 12.

The pair blasted off from the European Spaceport in Kourou, French Guiana, atop a Soyuz rocket at 11:51 GMT December 17th 2015. While the Russian lifter hoisted the satellites into low orbit, the final task of getting them to their final Medium Earth Orbit at an altitude of roughly 23,500km is a job for the restartable, autonomous Fregat upper stage.

The Galileo project kicked off in earnest back in October 2011, with the launch of two operational satellites as part of the In-Orbit Validation (IOV) phase of the program. Two further IOV satellites were sent heavenwards in October 2012, before the "Full Operational Capability" (FOC) launches commenced.

With today's lift-off, the Galileo FOC fleet aloft now comprises eight satellites. Galileos 5 and 6 launched in August 2014. Galileos 7 and 8 departed planet Earth back in March 2015, followed by Galileos 9 and 10 in September.

The full-fat system, comprising 24 operational satellites and six orbiting spares, is due to be up and running by 2020, offering one-meter accuracy. The European Space Agency says: "The Galileo navigation signals will provide good coverage even at latitudes up to 75 degrees north, which corresponds to Norway's North Cape - the most northerly tip of Europe - and beyond.

"The large number of satellites together with the carefully optimized constellation design, plus the availability of the three active spare satellites per orbital plane, will ensure that the loss of one satellite should have no discernible effect on the user."

SpaceX Selects 124 Engineering Teams to do Battle in Hyperloop Pod Design Competition

As reported by GizMag: SpaceX itself might not be building Elon Musk's Hyperloop, but it is making every effort to push things along. Earlier this year it announced the construction of a 1-mile (1.6-km) test track and it has now invited over 120 engineering teams to show off design concepts for a Hyperloop pod to a panel of judges in January. The most promising will then put their human-scale prototypes through their paces at SpaceX HQ the following US summer.  

SpaceX announced its Hyperloop Pod Competition in June, encouraging engineering teams to develop their own designs for passenger capsules that could be shuttled through the system's frictionless tubes at up to 760 mph (1,223 km/h). Since then it has received more than 1,200 submissions, but has now whittled that number down to 124 entrants who will present their concepts at the SpaceX Hyperloop Pod Competition Design Weekend at Texas A&M University on January 29 and 30.
Universities from all over the world will be represented, including teams from India's Vellore Institute of Technology and Uzbekistan's Turin Polytechnic University in Tashkent, along with names already well established in engineering circles like Stanford University and MIT. The full list can be viewed here.

The teams will present their designs to a panel made up of judges from SpaceX, Tesla and Texas A&M. From there, a number will be shortlisted and move on to building functional prototypes for the final phase of the competition. This will take place in the coming US summer at SpaceX's Hyperloop test track adjacent to its California headquarters.

Two unrelated companies are in the process of building their own Hyperloop test tracks, with the view to making the futuristic transport system more than a pipe dream. Hyperloop Transportation Technologies is constructing a 5-mile (8-km) track in Quay Valley, a proposed self-sustaining model town in California's Central Valley. The similarly named Hyperloop Technologies plans to begin open air-testing on its own track next month.
