When NASA’s latest Mars rover, Perseverance, launches this week, the robot will have a tiny stowaway on board: a small box-shaped helicopter. If the copter manages to successfully hover above the Martian terrain, it’ll be the first time that a human-made vehicle has ever flown on another world — and it could open up a whole new way of exploring the Solar System in the future.

The helicopter, named Ingenuity, is not the main focus of the rover. Perseverance’s biggest goal is to look for signs of life on Mars and dig up samples of dirt that could one day be returned to Earth for study. But engineers managed to find room under the rover’s belly to stow the tiny helicopter. At some point during Perseverance’s journey, the rover will deploy...

Image
Image: Samsung Samsung introduced its first TVs with Micro LED technology at CES 2021, and they wound up being perhaps the best sets that the company has produced yet — not counting the exorbitantly priced The Wall, that is. So this year, Samsung is opting for a different approach: it’s taking smaller strides in hardware and focusing more of its efforts on software refinement and new features. Samsung’s 2022 TVs will continue to run the company’s Tizen OS, but they’ll now come with a totally revamped home screen that’s described as “a testament to our vision for the future of TVs.” The first part of the new user experience is what Samsung calls the Media Screen.

Image
The L’Oreal ColorSonic is meant to make at-home hair coloring more convenient. | Image: L’Oreal While you might not expect it, L’Oreal has been a regular at CES these past few years, launching everything from wearable UV and pH sensors to an AI-powered skin care gadget . This year, the company is back with yet another invention, the Colorsonic — a device meant to make dying your hair at home a hell of a lot more convenient. The Colorsonic doesn’t look too far off from other hair styling gadgets. The top half has a nozzle with bristles, while the bottom half stores a cartridge containing a “precise mix of developer and formula.” The device works by dispensing the correct amount of hair color and then the bristles oscillate over 300 times a minute at a specific angle to evenly apply the color. Basically, the idea behind the device is... Continue reading…
