China’s Spaceplane Has Released Multiple Mystery Objects In Orbit

China’s shadowy miniature spaceplane appears to have deployed at least six objects into orbit while conducting its latest mission, its third. The reusable space vehicle, which is understood to be broadly comparable to the U.S. Space Force’s X-37B, clearly has military applications, although the exact nature of its payloads remains mysterious.

The Chinese spaceplane, named Shenlong (meaning Divine Dragon), has placed the objects in Earth orbit since it was launched from the Jiuquan Satellite Launch Center on December 14. The existence of these objects has been confirmed by amateur spacecraft trackers.

The spaceplane itself is launched atop a traditional space launch rocket and is propelled into orbit using a secondary booster. It returns to Earth in an unpowered mode, much like the X-37B.

One amateur astronomer, Scott Tilley, told Space.com’s Brett Tingley that some of the objects — which have been named A, B, C, D, E, and F — seem to be transmitting signals. Tilley has described these objects as “mysterious wingmen,” a nod to the “loyal wingman” terminology used for the drones that operate collaboratively with piloted aircraft. The Shenlong, of course, is uncrewed.

Tilley also provided Space.com with details on the differences in transmissions between the objects, with Object A said to be sending small amounts of data, while Objects D and E seem to be only emitting “placeholder” signals, without accompanying data.

DREAM CHASER SPACEPLANE IS GEARING UP TO HELP NASA DELIVER CARGO TO THE INTERNATIONAL SPACE STATION

An innovative new spaceplane cargo system is advancing toward its first delivery to the International Space Station (ISS), as one of NASA’s commercial partners providing resupply services.

The Dream Chaser spaceplane, designed by Colorado-based Sierra Space, is an uncrewed cargo spacecraft that is expected to carry out its first demonstration mission next year, NASA said in a news release.

Currently the only commercial runway-capable spaceplane, the reusable cargo system comprises two components, the Dream Chaser, a lifting body spacecraft, and its cargo module, Shooting Star. The system, a modified HL-20 spacecraft, is designed for reuse as many as 15 times and can be prepared for launch in as little as 24 hours.

Dream Chaser’s first flight will undertake in-orbit demonstrations next year to help Sierra Space and its partners at NASA gauge its readiness for future resupply missions. Flight controllers with Sierra Space will oversee the launch, with assistance and support from NASA personnel and the agency’s launch facilities.

At the time of launch, Dream Chaser’s wings are folded within five-meter fairing panels that are jettisoned once they reach orbit, which protect the spacecraft while being carried to orbit on board a United Launch Alliance (ULA) Vulcan Centaur rocket.

On its way to the ISS, Dream Chaser’s wings are deployed, as well as solar arrays on its cargo module, Shooting Star, which can deliver pressurized and unpressurized cargo to the ISS, as well as retrieve it and bring it back to Earth. The cargo module is disposable, and after each use, it can be jettisoned before reentry.

Before entering joint operations with NASA Mission Control in Houston, Dream Chaser will first demonstrate attitude control, abort capabilities, and other crucial maneuvers well beyond the vicinity of the ISS during initial test phases. These will be followed by near-field demonstrations, which will feature sensor systems and response commands that test its ability to maneuver within proximity to the space station before ultimately being cleared to approach it.

Amazon Fires Up Its Space Lasers 

A shoot-out featuring thousands of lasers is about to break out in low earth orbit. Luckily, no one will get hurt—the lasers’ targets are the protagonists’ own communications satellites.

Amazon has just announced that two of its prototype internet satellites equipped with infrared lasers transferred data at 100 gigabits per second over a distance of nearly 1000 kilometers. The company says all of its upcoming 3236 Project Kuiper satellites will include such interlinks, forming a high-speed mesh network to route data around the world.

SpaceX’s rival Starlink system, which already boasts over 1.5 million customers including the Ukrainian military, has been experimenting with optical interlinks for about a year. It recently claimed to have more than 8,000 space lasers on its newest generation of satellites, which began launching earlier this year.

Now the race is on to build the first complete optical inter-satellite link (OISL) constellation, at a price that’s competitive with terrestrial 5G and fiber networks.

AI gives birth to AI: Scientists say machine intelligence now capable of replicating without humans

Artificial intelligence models can now create smaller AI systems without the help of a human, according to research published Friday by a group of scientists who said the project was the first of its kind.

Essentially, larger AI models — like the kind that power ChatGPT — can create smaller, more specific AI applications that can be used in everyday life, a collaboration between Aizip Inc. and scientists at the Massachusetts Institute of Technology and several University of California campuses demonstrated. Those specialized models could help improve hearing aids, monitor oil pipelines and track endangered species.

“Right now, we’re using bigger models to build the smaller models, like a bigger brother helping [its smaller] brother to improve. That’s the first step towards a bigger job of self-evolving AI,” Yan Sun, CEO of the AI tech company Aizip, told Fox News. “This is the first step in the path to show that AI models can build AI models.”

Eye-Ball Scanning Digital ID Company Worldcoin Integrates With Reddit, Telegram, and More

Worldcoin, the eye-ball scanning protocol co-founded by Sam Altman, is cracking open a wider integration network by adding support for platforms such as Minecraft, Reddit, Telegram, Shopify, and Mercado Libre to its World ID offering. This comes on the back of the cohesive upgrades it has already sealed with Discord, Talent Protocol, and Okta’s Auth0.

Digital ID systems, like the one used by WorldCoin, raise significant privacy concerns due to the sensitive nature of the biometric data they collect and store. The other issue is that identity becomes immutable.

Consider a scenario where your digital identity becomes inaccessible, perhaps due to regulatory action or technical issues. In conventional financial systems, including traditional cash and most cryptocurrencies, you can simply create a new wallet and start over. However, with systems tied to unique biometric identifiers, such as iris scans, you can’t easily replace your identity. Unlike a plot from a science fiction movie, obtaining a new iris scan is not a feasible option.

WORLD’S FIRST SUPERCOMPUTER THAT WILL RIVAL THE HUMAN BRAIN TO BE UNLEASHED IN 2024

Researchers in Australia are developing the world’s first supercomputer capable of simulating networks at a scale comparable to the human brain, which they say will be complete by next year.

The remarkable supercomputer, which its creators call DeepSouth, is a neuromorphic system designed to be capable of simulating the efficiency of biological processes, achieved with hardware that emulates large networks of spiking neurons at an astounding 228 trillion synaptic operations each second.

The human brain is remarkable for its efficiency. Capable of processing the equivalent of one billion-billion mathematical operations per second, known as an exaflop, each second while only using 20 watts of power, researchers have long hoped to be able to replicate the way our brains process information.

Under development by a research team at Western Sydney University, Australia, the astounding 228 trillion synaptic operations per second that DeepSouth is expected to be capable of will not only rival the capabilities of the human brain, but also pave the way toward the future creation of synthetic brains that may exceed the remarkable capabilities ours possess.

Brain implants revive cognitive abilities long after traumatic brain injury in clinical trial

In 2001, Gina Arata was in her final semester of college, planning to apply to law school, when she suffered a traumatic brain injury in a car accident. The injury so compromised her ability to focus she struggled in a job sorting mail.

“I couldn’t remember anything,” said Arata, who lives in Modesto with her parents. “My left foot dropped, so I’d trip over things all the time. I was always in car accidents. And I had no filter—I’d get pissed off really easily.”

Her parents learned about research being conducted at Stanford Medicine and reached out; Arata was accepted as a participant. In 2018, physicians surgically implanted a device deep inside her brain, then carefully calibrated the device’s electrical activity to stimulate the networks the injury had subdued. The results of the clinical trial were published Dec. 4 in Nature Medicine.

She noticed the difference immediately. When she was asked to list items in the produce aisle of a grocery store, she could rattle off fruits and vegetables. Then a researcher turned the device off, and she couldn’t name any.

“Since the implant I haven’t had any speeding tickets,” Arata said. “I don’t trip anymore. I can remember how much money is in my bank account. I wasn’t able to read, but after the implant I bought a book, ‘Where the Crawdads Sing,’ and loved it and remembered it. And I don’t have that quick temper.”

For Arata and four others, the experimental deep-brain-stimulation device restored, to different degrees, the cognitive abilities they had lost to brain injuries years before. The new technique, developed by Stanford Medicine researchers and collaborators from other institutions, is the first to show promise against the long-lasting impairments from moderate to severe traumatic brain injuries.

Pentagon Seeks EMP Weapon To Eliminate Drone Swarms

Faced with the reality that drones are reshaping the modern battlefields in Ukraine and Gaza, the Pentagon has been tasked with finding a budget-friendly solution to eliminate these “flying IEDs.” While missiles are too expensive, and laser beams are a distant dream, the next best cost-effective weapon US military officials are eyeing up could be electromagnetic pulse weapons to counter drone swarms.

According to the System for Award Management (SAM.gov) website, the US Air Force has published a contract opportunity for private industry titled “Electromagnetic Pulse (EMP) Defense Against Unmanned Aircraft Systems (UAS).” 

The service outlined the drone-killing features of the new EMP weapon it is seeking:

“The Air Force Research Laboratory (AFRL/RI) is conducting market research to seek information from industry on the landscape of research and development (R&D) for available Electromagnetic Pulse (EMP) solutions towards countering multiple Unmanned Aircraft Systems (UAS). EMP solutions could be ground and/or aerial based that provide effective mitigation against Department of Defense (DoD) UAS groups 1, 2, and smaller group 3 aircraft.”

GOVERNMENT-FUNDED STUDY EXPLORES WARP DRIVES AS MEANS OF FASTER-THAN-LIGHT COMMUNICATION THROUGH “HYPERWAVES”

Exploring faster-than-light (FTL) communication, a concept rooted in science fiction has intrigued scientists and engineers for years. The proverbial little brother to FTL travel, where a spacecraft is sent at warp to a distant location, FTL communication may be a promising first step, and one theorist is shifting focus to “Hyperwaves,” a method of sending messages across vast distances faster than the speed of light.

The recent paper, partially funded by the British government’s Defence Science and Technology Laboratory and the Ministry of Defence, uploaded to arXiv, “Hyperwave: Hyper-Fast Communication within General Relativity,” by Dr. Lorenzo Pieri, offers a novel approach to this challenge. It suggests using “hypertubes” – structures that can manage the distribution and configuration of negative energy – to accelerate and decelerate warp bubbles, facilitating FTL communication.

China’s online censors target short videos, artificial intelligence and ‘pessimism’ in latest crackdown

China’s internet censors are targeting short videos that spread “misleading content” as part of its latest online crackdown.

The Cyberspace Administration of China said on Tuesday that it would target short videos that spread rumours about people’s lives or promoted incorrect values such as pessimism – included for the first time – and extremism.

The campaign would also target fake videos generated using artificial intelligence, the watchdog said.

The country’s top censorship body has been running an annual online crackdown known as “Qing Lang”, which means clear and bright, since 2020.

It said this year’s crackdown would benefit people’s mental health and create a healthy space for competition that would help the short video industry develop.

The country’s best known short video platform is Douyin – the Chinese sibling of TikTok – but content is shared on a number of other Chinese social media platforms, including major players such as WeChat and Weibo.

The watchdog said one of the targets of the latest campaign would be content producers who make up stories about social minorities to win public sympathy. It would also crack down on people staging incidents, “making up fake plots and spreading panic”.
