Imagine a future where internet connections are not only lightning-fast but also remarkably reliable, even in crowded spaces. This vision is rapidly approaching reality, thanks to new research on terahertz communications technologies. These innovations are set to transform wireless communication, particularly as communications technology advances toward the next generation of networks, 6G.

I’m an engineer who focuses on photonics, the study of how light and other electromagnetic waves are generated and detected. In this research, my colleagues and I have developed a silicon topological beamformer chip. The paper is published in the journal Nature. Topological.

Terahertz frequencies are crucial for 6G, which telecommunications companies plan to roll out around 2030. The radio frequency spectrum used by current wireless networks is becoming increasingly congested. Terahertz waves offer a solution by using the relatively unoccupied portion of the electromagnetic spectrum between microwaves and infrared. These higher frequencies can carry massive amounts of data, making them ideal for the data-intensive applications of the future.

SpaceX satellite internet service Starlink said it will comply with court orders to block social network X in Brazil.

WASHINGTON — SpaceX resumed launches of its Falcon 9 rocket early Aug. 31 after the Federal Aviation Administration ended a brief grounding of the vehicle.

One Falcon 9 lifted off from Cape Canaveral Space Force Station’s Space Launch Complex 40 at 3:43 a.m. Eastern, placing 21 Starlink satellites into orbit. It was followed at 4:48 a.m. Eastern by another Falcon 9 lifting off from Vandenberg Space Force Base’s Space Launch Complex 4E, also delivering 21 Starlink satellites to low Earth orbit. The 65 minutes between launches is the shortest interval yet between Falcon 9 launches.

The launches were the first by SpaceX since the Aug. 28 launch of a Falcon 9 where the booster was lost during landing on a droneship in the Atlantic Ocean. While the rocket successfully placed its payload of Starlink satellites into orbit, the Federal Aviation Administration ordered a halt in Falcon 9 launches later that day to investigate any public safety implications of the failed landing.

Elon Musk said Starlink’s direct-to-cellular service would provide free emergency services at SpaceX seeks FCC approval for the technology.

ICYMI: Elon Musk’s social media platform X was instructed by a Brazilian court to name a local representative, but failed to do so.

The justice said the platform will stay suspended until it complies with his orders, and also set a daily fine of 50,000 reais ($8,900) for people or companies using…

SAO PAULO — Brazil started blocking Elon Musk’s social media platform X early Saturday, making it largely inaccessible on both the web and through its mobile app after the company refused to comply with a judge’s order.

Three days ago, an old Falcon 9 booster crashed and exploded while landing on a drone ship during its 23rd landing.

The FAA has cleared SpaceX to launch the Falcon 9 while the investigation into Wednesday’s mishap wraps up.

While the idea of a quantum internet has a huge amount of potential, getting it hooked up to the regular old internet has its challenges.

Now a new study hints at how existing and future networks could be combined.

An experiment conducted by researchers from Leibniz University Hannover in Germany show how quantum information and the classic 1s and 0s of conventional data could be beamed down the same optical fiber.

Optical fiber, as a physical medium for information transmission, is the “highway” of modern economic and social development. However, with the continuous emergence of high-speed and high-capacity communication scenarios such as virtual reality, 5G, intelligent driving, and the Internet of Things (IoT), there is an upper limit to the communication capacity (traffic flow) of the traditional single-mode fiber-optic communication system (highway).

Reports that each of NASA’s Artemis launches could cost as much as $4.1 billion…

“Costs going up faster than the tower,” self-described internet rocket scientist Scott Manley joked at the time.

NASA used its Mobile Launcher 1 for its inaugural — albeit uncrewed — Artemis mission in late 2022. According to a 2020 audit, the tower, which was originally built for NASA’s canceled Constellation program, cost $234 million to develop.
