Tech companies continued to draw criticism for their roles in political and social scandals, most notably when whisteblower and former Facebook employee Frances Haugen testified to lawmakers. Undeterred, Facebook rebranded itself Meta and said it would now focus on building the metaverse. Twitter CEO Jack Dorsey stepped down and likewise changed the name of his company Square to Block in a not-so-subtle nod to the blockchain.

Meanwhile, volatile cryptocurrencies set new records, their prices jumping and crashing on a tweet. NFTs, a once-obscure type of cryptoasset, went on an eye-watering tear as redditors pushed meme stocks skyward. It was also the year of ever-bigger AI. Machine learning models surpassed a trillion parameters, designed computer chips, and tackled practical problems in biology, math, and chemistry. Elsewhere, billionaires went to space, regular folks bought 3D printed houses, fusion power attracted billions in investment, gene editing trials hit their stride, and “flying car” companies hit the New York Stock Exchange.

For this year’s list of fascinating stories in tech and science, we sifted our Saturday posts and selected articles that looked back to where it all began, glanced ahead to what’s coming, or otherwise stood out from the chatter to stand the test of time.

Space Exploration Technologies Corporation’s (SpaceX) ch8ef executive officer Mr. Elon Musk has shared the latest details for his company’s Starlink satellite internet constellation. Starlink is SpaceX’s internet service which uses low Earth orbit (LEO) small satellites to beam down the Internet to its users. Due to a rapid cadence of launches, SpaceX has ensured that Starlink is the world’s largest internet constellation in service, and the company is currently upgrading the satellites with laser based connectivity. This will allow Starlink to expand its coverage and reach areas that cannot be served without ground stations to connect the satellites and the users to internet servers.

Starlink Will Soon Start To Operate Laser Links Between Satellites Confirms Musk

Mr. Musk shared the latest details through his social media platform Twitter, as he outlined the number of Starlink satellites currently in orbit and his company’s plans to activate newer spacecraft capable of optical communication. These are crucial for evaluating the internet service’s current capacity, which has come under fire from rivals in proceedings for spectrum sharing and licensing currently underway at the Federal Communications Commission (FCC).

Elon Musk—via Starlink, a division of SpaceX—is in talks with “several” airlines to provide in-flight WiFi for passengers. His plan is to use Starlink’s ever-growing megaconstellation of satellites to equip customers with better WiFi while they fly the friendly skies.

Jonathan Hofeller, SpaceX’s vice president of Starlink and commercial sales, gave out details on the ambitious plan during a panel at the Connected Aviation Intelligence Summit on Wednesday.

I’ve posted some vids of her before. But here she says at 3:52 that she thinks stopping the aging process is farfetched.

Dr. Morgan Levine, a professor who specializes in the biology of aging, answers the internet’s burning questions about aging. Is there anyway to stop aging? Is aging a disease? Do you age slower in space? Dr. Levine answers all these questions and much more!

The metaverse, which requires a massive amount of computing power, is set to benefit global chipmakers— but other tech-related industries could also gain from it, analysts say.

Widely seen as the next generation of the internet, the metaverse refers broadly to a virtual world where humans interact through three-dimensional avatars that can be controlled via virtual reality headsets like Oculus.

Through the metaverse, users can engage in virtual activities such as gaming, virtual concerts or live sports.

This is interesting. It looks like SpaceX is abandoning their backup plan to launch V2.0 Starlink satellites with the Falcon 9 and instead they are going to launch them with Starship instead. They are also saying they will be ready to launch them as soon as 2 months from now. This confirms the rumors that I’ve been hearing that the Raptor 2 engine for Starship is much more stable than the Raptor 1 engines were.

Note that this means they are planning on launching satellites before they have perfected landing but this makes sense since they did the same with the Falcon 9, crashing and burning 19 rockets in a row until they were able to land part of one. It should take 5 or less orbital attempts to land the Starship booster stage. (They will lose a ton of engines with the booster stage so this will be a high priority to get working.)

TAMPA, Fla. — SpaceX has dropped a plan to use Falcon 9 to launch the 30,000 satellites in its proposed second-generation Starlink broadband constellation, and is instead focusing on a configuration leveraging its upcoming Starship vehicle.

We are currently witnessing an explosion of network traffic. Numerous emerging services and applications, such as cloud services, video streaming platforms and the Internet of Things (IOT), are further increasing the demand for high-capacity communications. Optical communication systems, technologies that transfer information optically using fibers, are the backbone of today’s communication networks of fixed-line, wireless infrastructure and data centers.

Over the past decade, the growth of the internet was enabled by a technique known as digital signal processing (DSP), which can help to reduce transmission distortions. However, DSP is currently implemented using CMOS integrated circuits (ICs), thus it relies heavily on Moore’s Law, which has approached its limits in terms of power dissipation, density and feasible engineering solutions.

As a result, distortions caused by a phenomenon known as fiber nonlinearity cannot be compensated by DSP, as this would require too much computation power and resources. Fiber nonlinearities remain the major limiting effect on long-distance transmission systems.

SpaceX launched another batch of Starlink satellites to the fourth shell of the constellation for the first global orbital launch attempt of the year.

Lifting off from historic Launch Complex 39A (LC-39A), the Starlink Group 4–5 mission lifted 49 Starlink v1.5 satellites southeastward from Kennedy into a 210 × 339 km low Earth orbit with an inclination of 53.22 degrees.
