Semiautonomous Cars Have Flaws. That's Why They Need Tests

August 09, 2018

These days, modern cars come with sophisticated driver assistance tools, like adaptive cruise control, which maintains a set distance from the car in front, and active steering, which keeps a vehicle in its lane. They can also brake automatically if the driver doesn’t spot a stopped object ahead, and warn when there’s a motorbike hovering in a driver’s blind spot.

China has outspent the US by $24 billion in 5G technology since 2015, study shows

August 09, 2018

China has in recent years outspent the U.S. by $24 billion in the area of next-generation mobile internet technology known as 5G, potentially creating a "tsunami" that will be difficult to catch up with, according to a Deloitte study published Tuesday.

Curiosity Rover Begins Its 7th Year on Mars Still Going Strong

August 09, 2018

It was a crazy idea on the face of it -- sending a $2.5 billion robot to another planet with a complex rocket sled contraption to get it safely to the surface. It worked, though, and Curiosity began its exploration of the red planet six years ago. As the rover begins its seventh year on Mars, let’s look at how it got there and where it’s going.

America Is Not Ready for Exploding Drones

August 09, 2018

Top U.S. officials, including FBI director Christopher Wray, have warned that America is vulnerable. Washington, D.C., for example, has what Department of Homeland Security officials have called “the most tightly controlled airspace in the country;” it’s illegal to fly drones anywhere in the District. And yet: In 2015, an off-duty government employee managed to crash a drone onto the White House lawn.

Russia Is Slowly Declining As a Space Superpower

August 08, 2018

Complaints about Chinese acquisition of Russian rocket technology have become a common refrain in Russian state media. (The Kremlin exercises heavy influence over Lenta.ru’s editorial decision-making, like many of the country’s media outlets.) China is now close to a working copy of the Soviet-designed yet still effective RD-180 rocket engine, due to what Russia has painted as a multi-decade ripoff of its technology.

Opposition to a Space Force Simmers in the Senate

August 07, 2018

The Pentagon is in the final stages of preparing a report to lawmakers laying out the groundwork for the change, including initial steps they can make without Congress. But the final step--officially creating a new service branch—will require legislative authorization. And it is Senate Republicans who could stand in the way of Trump’s so-called Space Force; the House has already signaled its support for the move.

5 Unanswered Questions About Space Force

August 07, 2018

Space Force is getting closer to reality. As early as this week, the Pentagon is expected to announce various steps to reorganize the military’s space-related procurement and operations, culminating in a planned request for congressional action to authorize the creation of a separate service branch for space.

NASA Says Terraforming Mars Is Currently Impossible

August 06, 2018

Mars has long been seen as a potential second home for humanity, but it won’t be a comfortable place to hang your hat until we’ve addressed the lack of breathable air. According to NASA, fantasies about terraforming the red planet are premature. A new analysis of Mars and its composition shows that we’re nowhere near being able to terraform the planet with current technology.

An AI-driven robot hand spent a hundred years teaching itself to rotate a cube

August 06, 2018

AI researchers have demonstrated a self-teaching algorithm that gives a robot hand remarkable new dexterity. Their creation taught itself to manipulate a cube with uncanny skill by practicing for the equivalent of a hundred years inside a computer simulation (though only a few days in real time).
