NASA’s Dragonfly will fly across the surface of Titan, Saturn’s ocean moon

NASA has just announced its next big interplanetary mission: Dragonfly, which will deliver a Mars Rover-sized flying vehicle to the surface of Titan, a moon of Saturn with tantalizing life-supporting qualities. The craft will fly from place to place, sampling the delicious organic surface materials and sending high-resolution pictures back to Earth. Dragonfly will launch […]

This robot crawls along wind turbine blades looking for invisible flaws

Wind turbines are a great source of clean power, but their apparent simplicity — just a big thing that spins — belie complex systems that wear down like any other, and can fail with disastrous consequences. Sandia National Labs researchers have created a robot that can inspect the enormous blades of turbines autonomously, helping keep […]

The Raspberry Pi Foundation unveils the Raspberry Pi 4

The Raspberry Pi 4 is here — and it’s an awesome upgrade. Earlier rumors said that it would take a while before a major Raspberry Pi upgrade, but it’s available starting today. When it comes to physical design, the Raspberry Pi 4 Model B looks a lot like the Raspberry Pi 3 Model B+, the […]

Tripping grad students over and over for science (and better prosthetic limbs)

Tripping grad students over and over for science (and better prosthetic limbs)

Prosthetic limbs are getting better, but not as quickly as you’d think. They’re not as smart as our real limbs, which (directed by the brain) do things like automatically stretch out to catch ourselves when we fall. This particular “stumble reflex” was the subject of an interesting study at Vanderbilt that required its subjects to […]

Crowdfunded spacecraft LightSail 2 prepares to go sailing on sunlight

Crowdfunded spacecraft LightSail 2 prepares to go sailing on sunlight

Among the many spacecraft and satellites ascending to space on Monday’s Falcon Heavy launch, the Planetary Society’s LightSail 2 may be the most interesting. If all goes well, a week from launch it will be moving through space — slowly, but surely — on nothing more than the force exerted on it by sunlight. LightSail […]

NASA’s X-59 supersonic jet will have a 4K TV instead of a forward window

NASA’s X-59 supersonic jet will have a 4K TV instead of a forward window

NASA’s X-59 QueSST experimental quiet supersonic aircraft will have a cockpit like no other — featuring a big 4K screen where you’d normally have a front window. Why? Because this is one weird-looking plane. The X-59, which is being developed by Lockheed Martin on a $247 million budget, is meant to go significantly faster than […]

This $99 AirPower knockoff is available for order now

This $99 AirPower knockoff is available for order now

There are a number of key differences between Apple’s AirPower and lookalike knockoff, AirUnleashed. The most pertinent one, however, is that one of the two is actually available for purchase. Apple gave up the AirPower ghost back in March, after having gone silent on the product for some time, citing an inability to “achieve [its] […]
