In a successful demonstration of new laser communications capabilities, NASA beamed an ultra-high definition video across 19 million miles of space from its Psyche spacecraft to Earth earlier this month. It’s the first time a UHD streaming video has been sent from deep space via laser. The history-making video? A 15-second clip of an orange cat named Taters chasing a laser dot.
The signal from the video, sent on December 11, made it to Earth in 101 seconds from Psyche’s location at the time, which was about 80 times as far as the distance between Earth and the moon. It was uploaded before the mission launched, and sent back home by a flight laser transceiver aboard Psyche at a rate of 267Mbps. The spacecraft, which set off on its journey in October, is on its way to study a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.
“Despite transmitting from millions of miles away, it was able to send the video faster than most broadband internet connections,” said Ryan Rogalin, the receiver electronics lead for the project at NASA’s Jet Propulsion Lab. “In fact, after receiving the video at Palomar, it was sent to JPL over the internet, and that connection was slower than the signal coming from deep space.”

Yesterday Google announced that they’ll be moving away from naming Android releases after desserts, and Android Q will officially be Android 10. There’s a ton of good reasons for that, especially with certain desserts and treats not really making sense in some countries around the world. Q, for example, would’ve actually be really hard to […]

Amazon is taking Microsoft’s naming approach to hardware devices, as they’ve just introduced the somewhat more privacy focused Echo Show 5. The naming comes from the device’s 5.5-inch screen, which is quite a bit smaller than the 10.1-inch display on the larger Echo Show. This nestles the Echo Show 5 right in between the Echo […]

DxOMark has declared the camera on the Samsung Galaxy S7 Edge the best they’ve ever tested.
The Galaxy S7 Edge this week received a score of 88 from DxOMark, which is the highest recorded score for outstanding image quality.
From Samsung:
“From blink-of-an-eye autofocus delivering fewer blurry photos, to superior low-light photography, to significant advancements in video capture, the Galaxy S7 Edge gives users a chance to capture every memory reliably and true to life. Central to this performance is the groundbreaking dual-pixel technology in the Galaxy S7 Edge camera—previously found only in expensive DSLR cameras.”
This is not the first superlative for Samsung’s new flagship line. The 5.1-inch Quad HD (2560×1440) Super AMOLED display of the Galaxy S7 was named by DisplayMate as the best ever.
