WASHINGTON — A Falcon 9 launched another set of Starlink satellites March 14, with the rocket’s first stage setting a record with its ninth launch and landing.

The Falcon 9 lifted off from Launch Complex 39A at the Kennedy Space Center at 6:01 a.m. Eastern. The upper stage deployed its payload of 60 Starlink satellites into orbit 65 minutes later, bringing the size of the broadband internet constellation to 1260 satellites.

The launch was the eighth for the Falcon 9 this year, and took place a little more than 72 hours after another Falcon 9 launch of Starlink satellites. Six of the eight Falcon 9 launches this year have been dedicated to Starlink, and one of the other two, the Transporter-1 dedicated rideshare flight, also carried 10 Starlink satellites.

CAMBRIDGE, Mass.—(BUSINESS WIRE)—Engineers from HyperLight, a leader in the commercialization of thin-film lithium niobate (LN) photonic integrated circuits (PICs), have achieved breakthrough voltage-bandwidth performances in integrated electro-optic modulators. The broadband electro-optic PIC could lead to orders of magnitude energy consumption reduction for next generation optical networking.

Energy consumption in optical networking for ethernet, data centers and 5G is soaring as a result of the rapidly growing data traffic. This is because of the limited performance of existing electro-optic modulators, the key element in converting data from the electrical to optical domain at high speed for optical networks. Current electro-optic modulators require extremely high radio-frequency (RF) driving voltages (5 V) as the analog bandwidth in ethernet ports approaches 100 GHz for future terabits per sec capacity transceivers. In comparison, a typical CMOS RF modulator driver delivers less than 0.5 V at such frequencies. Compound semiconductor modulator drivers can deliver voltage 1 V at significantly increased cost and energy consumption but still fall short to meet the optimum driving voltage. The limited voltage-bandwidth performance in electro-optic modulators poses a serious challenge for meeting tight power consumption requirements from network builders.

Elon Musk’s SpaceX is preparing to further expand testing of its Starlink satellite internet in a test for the U.S. Air Force, an FCC request revealed.

Elon Musk’s SpaceX is preparing to further test its Starlink satellite internet in a demonstration for the U.S. Air Force, the company revealed in a recent request to the Federal Communications Commission.

“SpaceX seeks to make minor modifications to its experimental authorization for additional test activities undertaken with the federal government,” the company wrote to the FCC in a filing on Thursday.

These shifting dynamics in India’s digital marketplace are yet another warning sign of what’s been dubbed the splinternet, foreshadowing a possible world where each country sticks to its own apps and abandons the open and global nature of the internet. For now, however, these homegrown apps may find it difficult to compete at the same level unless the government decides to ban Facebook and Twitter, too.

While Twitter finds itself in a prolonged standoff with the Indian government over the company’s refusal to take down certain accounts, a senior executive of a very similar Indian social network says the sudden attention on his app has been “overwhelming.”

“It feels like … you’ve just been put in the finals of the World Cup suddenly and everyone’s watching you and the team,” Mayank Bidawatka, co-founder of Koo, told CNN Business.

SpaceX has launched 1265 Starlinks to date with another 60 awaiting launch this weekend. Thousands more are planned.

Researchers have developed a new data transfer system that is 20 times faster than USB 3.0.

This combines high-frequency silicon chips with a polymer cable as thin as a strand of hair. The system could boost energy efficiency in data centres and lighten the loads of electronics-rich spacecraft. Researchers presented their breakthrough at the recent IEEE International Solid-State Circuits Conference, held virtually.

“There’s an explosion in the amount of information being shared between computer chips – cloud computing, the Internet, big data. And a lot of this happens over conventional copper wire,” says Jack Holloway, who led the research. Holloway completed his PhD in MIT’s Department of Electrical Engineering and Computer Science last year and currently works for Raytheon.

It was the 6th launch and landing for this Falcon 9 first stage.

A SpaceX Falcon 9 rocket launched a new batch of 60 Starlink internet satellites to orbit early this morning (March 11) and nailed its landing on a floating platform at sea.

MIT scientists demonstrate a hair-like plastic polymer cable that can transmit data 10 times as fast as USB.

How fast does data flow? The answer: not fast enough.

The search for more efficient data-transfer solutions to meet the ever-increasing demand for computation never ends. Even today, most data transmission happens via traditional copper cables, which are power-hungry, leading to a compromise between data exchange and energy consumed. Fiber-optic cables are an alternative, but they don’t work well with the silicon chips in our computing systems. Overcoming these limitations, while theoretically possible, can turn out to be prohibitively expensive, especially for electronics-rich applications like data centers, spacecraft, electric vehicles and so on.

SpaceX wants to begin connecting moving vehicles – from cars and trucks to jets and ships – to its Starlink satellite internet network, according to a request the company filed with the Federal Communications Commission.

“This application would serve the public interest by authorizing a new class of ground-based components for SpaceX’s satellite system that will expand the range of broadband capabilities available to moving vehicles throughout the United States and to moving vessels and aircraft worldwide,” SpaceX director of satellite policy David Goldman wrote in a letter to the FCC filed on Friday.

Starlink is the company’s capital-intensive project to build an interconnected internet network with thousands of satellites, known in the space industry as a constellation, designed to deliver high-speed internet to consumers anywhere on the planet.
