Following recent tests, Amazon is finally ready to launch its Project Kuiper space internet project in a bid to rival Elon Musk's Starlink, the company announced. The first batch of 27 satellites on the KA-01 (Kuiper Atlas 1) mission are set to launch into low earth orbit (LEO) aboard a United Launch Alliance Atlas V rocket on April 9th next week from Cape Canaveral if conditions allow. Amazon hopes to start offering the high-speed internet service "later this year," it said. Amazon's network will eventually comprise 3,200 satellites launched from partners including ULA, Arianespace, Blue Origin and even SpaceX. Much like that company's Starlink, Project Kuiper's service will cover the entire planet when completed. It will work with a dish as small as seven inches that will deliver speeds up to 100Mbps, smaller than Starlink's Mini, or up to 1Gbps with larger dishes. The company said the cost of terminals will be under $400. The satellites will cruise at 17,000 mph at 392 miles above earth, circling the planet in about 90 minutes. They'll use a dialectic mirror film coating that's supposed to scatter light and make them less visible to ground-based astronomers, Amazon said. SpaceX's constellation currently uses over 7,000 satellites, so the Project Kuiper and Starlink fleet will use over 10,000 LEO satellites once Amazon's network is complete. Amazon Amazon launched two test satellites in October 2023 and proclaimed its early tests a success, with the pair sending and retrieving data at speeds of up to 100 gigabits per second. Later in December, it bolstered the network with a network of high-speed laser cross-links that promise further speed boosts. The company claims its mesh network can move data about 30 percent faster than terrestrial fiber optic cables. Project Kuipers first launch will be the heaviest payload yet for the Atlas V, which will fly in its most powerful configuration. The rocket will include five solid rocket boosters in addition to the main booster, and a payload fairing 77 feet high and 16.4 feet wide. Despite past successful tests, the mission isn't without risk. "Weve done extensive testing on the ground to prepare for this first mission, but there are some things you can only learn in flight, and this will be the first time weve flown our final satellite design and the first time weve deployed so many satellites at once," Project Kuiper vice president Rajeev Badyal wrote. "No matter how the mission unfolds, this is just the start of our journey, and we have all the pieces in place to learn and adapt as we prepare to launch again and again over the coming years."This article originally appeared on Engadget at https://www.engadget.com/science/space/amazon-will-start-launching-its-project-kuiper-starlink-rival-next-week-123011012.html?src=rss

After years of lagging behind rivals when it comes to video capture (and then suddenly buying cinema camera manufacturer RED), Nikon is pushing new boundaries in that area. Its latest salvo is the $1,699 24-megapixel full-frame Z5 II, perhaps the cheapest mirrorless camera so far to support internal RAW video. It also offers improved autofocus with new AI powers, cleaner images and enhanced image stabilization. The Z5 II is a wholesale remake of the original Z5 and that starts with video. While still limited to 4K 30 fps and cropped 4K 60 fps, it can now capture those formats internally using the company's 12-bit N-RAW format with N-log, along with 10-bit H.265 and 8-bit H.264. Interestingly, it will record in N-RAW to SDXC UHS-II cards, since the camera lacks high-speed CFexpress slots. That likely means you'll need to buy very fast (and expensive) cards and that the N-RAW video will be highly compressed. Still, it's a feature available on no other camera in this price range. Nikon Nikon is also promising much-improved autofocus bolstered by a new image-processing engine and tech borrowed from its high-end Z9 and Z8 models. The Z5 II can now lock onto subjects more quickly, particularly human eyes, faces and bodies, and works in lower light down to -10 EV, compared to -3 EV before. Meanwhile, the AI system can detect up to nine subject types ranging from animals (including a Bird Detection mode) to bicycles. When working in Auto-Area AF, these subjects can be detected, focused on, and tracked automatically. Native ISOs have been boosted to 100-64000 (50-204,800 in expanded modes), up from a maximum 51,200 before. That should improve noise levels across the ISO ranges, the company said. However, resolution is still limited to 24 megapixels. Nikon In-body stabilization has been boosted to 7.5 stops with supported lenses, way up from five stops on the Z5. That's paired with electronic stabilization designed to keep handheld video steady. The Z5 II's viewfinder still offers a decent 3.69-million dots of resolution, but brightness has been boosted to 3,000 nits with 13 levels of brightness control. And it now comes with a 1.7-million-dot vari-angle display that's a big improvement from the previous model's tilt-only screen. The body now has a deeper grip to improve handling and comes with a one-touch Picture Control button for previewing and switching between color profiles in real time, matching a recent trend started by Fujifilm's X100 VI. Other features including dual SD UHS-II card slots, 3.5mm headphone and mic jacks, camera to cloud connectivity via Nikon's Imaging Cloud and a new weather-proof build "on par with the Z6 III," according to Nikon. The Z5 II looks to be an impressive hybrid full-frame camera for the money and rivals Sony and Canon don't really have anything in the same price range that can match it. However, it also comes at a price $300 higher than the Z5 was at launch. Still, it could tempt filmmakers and others away from similarly priced crop sensor cameras from the likes of Fujifilm and Sony. The Z5 II is now on pre-order for $1,699 (body only) or $1,999 with a 24-50mm f/4-6.3 kit lens.

Healthcare provider Akido Labs is bringing AI-powered medical care directly to New York City's busy ride-share drivers, addressing a critical gap in access for gig workers who often skip seeing a doctor to avoid losing income. The Los Angeles-based company will deploy its ScopeAI technology, which suggests diagnoses and treatments based on patients' symptoms and medical histories, with human doctors reviewing and making final decisions. The Wall Street Journal reports that Akido trained its model with historical data gathered from actual patient visits.Partnering with the Independent Drivers Guild and Workers Benefit Fund, Akido plans to position employees equipped with ScopeAI in strategic locations throughout New York. Appointments facilitated by the technology typically last 30-45 minutes, with certified medical assistants gathering patient information prompted by the AI system. The initiative aims to deliver "whole person care" addressing physical, behavioral and social health factors for drivers whose demanding schedules often exceeding 10 hours a day make traditional healthcare access challenging.
