Two mini-rovers have sent their first pictures back from the surface of the asteroid Ryugu, a day after they were dropped off by Japan’s Hayabusa 2 spacecraft. The pictures are blurry because they were taken while the rovers were hopping around the half-mile-wide space rock, more than 180 million miles from Earth. As fuzzy as they are, the photos represent a huge victory for the $150 million Hayabusa 2 mission, which was launched nearly four years ago to get an unprecedented look at the surface of an asteroid. The Japan Aerospace Exploration Agency first tried to do it more than a decade ago during the first Hayabusa mission, which targeted the asteroid Itokawa. That part of the mission fizzled, however, when the MINERVA rover carrier missed the mark and sailed off into interplanetary space. Hayabusa 2, in contrast, dropped its MINERVA-II-1 carrier right on target. The carrier deployed two 7-inch-wide, disk-shaped rovers that touched down on Ryugu’s rock-strewn terrain. It … [Read more...] about Japanese mini-rovers send back their first images as they hop around an asteroid
AT&T is tapping into Seattle’s historic coffee culture and its booming tech scene to create a first-of-its-kind experience for the global telecommunications company. On Capitol Hill, a neighborhood long known for its bars, cafes and hangout spaces, AT&T has found a home for “The Lounge,” combing high-tech retail, high-tech coffee and more. In a 3,000-square-foot space that looks nothing like what you’d walk into at the local mall, AT&T is opening what it calls a “second living room” for residents of the neighborhood — whether they use AT&T as a wireless provider or not. The Lounge sits beneath six stories of new residences in a building at the corner of East Thomas Street and Harvard Avenue East. AT&T has partnered with Ada’s Discovery Cafe, a second location for the owners of nearby Ada’s Technical Books and Cafe. The sleek coffee counter features cutting-edge coffee technology, including two towering, Japanese … [Read more...] about AT&T merges high-tech retail, coffee and hangout space in Seattle for its first ‘Lounge’ concept
Human relationships rely on trust, which is why the true history of authentication extends back long before the first written documents referencing it. I suspect that as early as humans formed tribes, they found ways to “authenticate” each other at night using specific sounds or watchwords. At the very least, Roman soldiers used watchwords regularly during the late B.C. and early A.D. periods. Over time authentication has become more complex. When you actually know someone, it’s easy to authenticate them by simply looking at them. However, as society has become more complicated, humans have had to develop new ways to authenticate people they don’t directly know. For example, a general in the Roman army may have led thousands of soldiers but couldn’t personally know them all. If one of those soldiers were to walk up on the street and claim to be part of his army, he’d need some way to prove it. Besides watchwords, society has developed many … [Read more...] about Digital authentication: The past, present and uncertain future of the keys to online identity

Astronomers on the team for NASA’s Transiting Exoplanet Survey Satellite mission, or TESS, are reporting their first potential planet discoveries, just days after the spacecraft’s first science image was unveiled. The first reported candidate planet was detected orbiting a star known as Pi Mensae, a sunlike yellow dwarf star nearly 60 light-years from Earth that was already known to harbor a world that’s more than 10 times as massive as Jupiter. The newly detected prospect is closer to its parent star in the southern constellation Mensa, making a complete orbit every 6.3 Earth days. In a paper published on the ArXiv pre-print website and submitted to the journal Astronomy & Astrophysics, the team’s scientists say Pi Mensae c appears to be about twice as wide as Earth. Its density is estimated as roughly equal to water’s density, which suggests the planet is a super-Earth that “may have held on to a significant atmosphere,” the … [Read more...] about TESS probe finds first potential planets
