Falcon Heavy is now scheduled to loft Astranis’ first commercial communications satellite to orbit next spring, the San Francisco-based company announced Thursday (Sept. 23).
Columbus OH (SPX) Sep 24 2021 — Engineering researchers have developed a method to use signals broadcast by Starlink internet service satellites to accurately locate a position here on Earth, much like GPS does. It is the first ti.
New chip eliminates the need for specific decoding hardware, could boost efficiency of gaming systems, 5G networks, the internet of things, and more.
A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND). The work was led by Muriel Médard, an engineering professor in the MIT Research Laboratory of Electronics.
Alphabet’s floating internet venture Project Loon may have been deflated, but its legacy looks set to live on through a new effort called Project Taara. The team has salvaged the technology to deliver internet connectivity with lasers, demonstrating the viability in a new test between two cities separated by the Congo River.
Originally a Google side hustle before being spun off into its own project by parent company Alphabet, Project Loon had lofty goals of connecting remote regions to the internet by beaming lasers between high-altitude balloons. After years of successful trials however, the project was eventually grounded in January 2021 due to sky-high costs.
The balloons may have been a bust, but there’s still life in the lasers. After all, wireless optical communication systems could help connect communities where it’s not feasible to build complex grids of underground optical fiber cables, and where cellular or satellite internet is patchy or expensive.
Internet on Mars!!
Elon Musk’s ‘Starlink’ is currently providing services in parts of the US and Canada and has plans to enter India by the end of 2021. Tech mogul Elon Musk, via his recent tweet, revealed that his satellite broadband company ‘Starlink’ will extend its services to Mars. Musk informed about this idea while replying to a user’s tweet last week, as per reports by The Science Times. Currently, the broadband internet provider is undergoing public beta testing in parts of the US and Canada.
Starlink will strengthen Starship’s communication Musk’s idea came to light when a user asked if Starlink will be deployed between Earth and Mars to strengthen communication for Starship is SpaceX’s ambitious project that is being touted as the vehicle that will ferry cargo and crew to the red planet and back in the coming years. In response to the user’s tweet, Musk amplified the excitement with one word, “yeah”.
What would a world without banks look like? The answer may lie in decentralized finance.
Decentralized finance is an emerging ecosystem of financial applications and protocols built on blockchain technology with programmable capabilities, such as ethereum and solana. The transactions get executed automatically through smart contracts on the blockchain, which includes the agreement of the deal.

Google runs a plethora of aspirational projects to explore one moonshot or another, but only some become real products. The company’s Project Loon internet balloons didn’t make the cut, having shut down in early 2021. However, one aspect of Loon has lived on to become its own Googley project. Google says it has used the Free Space Optical Communications (FSOC) links developed for Project Loon to beam hundreds of terabytes of data nearly five kilometers, no wires necessary.
Now under the purview of the company’s X labs, the little-known Project Taara is already enhancing connectivity in Kenya and India. Google says FSOC is essentially a fiber optic connection (up to 20 Gbps) without the wires, but it requires a direct line of sight. In Africa, Taara is now beaming data across the Congo River from Brazzaville in the Republic of Congo and Kinshasa in the Democratic Republic of Congo. After setting up the links over the past few years, Google is now sharing some of the project’s more impressive metrics.
Project Taara lead Baris Erkmen notes that Project Taara transmitted 700 TB over a recent 20-day period. This helped to back up wired connections in use by Google’s local partner Econet. Testing Taara in Africa makes sense because line-of-sight laser communication falls apart in a foggy locale like Google’s Bay Area home, and the fast-flowing Congo River has made connectivity in the region much more expensive.
Every piece of data that travels over the internet — from paragraphs in an email to 3D graphics in a virtual reality environment — can be altered by the noise it encounters along the way, such as electromagnetic interference from a microwave or Bluetooth device. The data are coded so that when they arrive at their destination, a decoding algorithm can undo the negative effects of that noise and retrieve the original data.
Since the 1950s, most error-correcting codes and decoding algorithms have been designed together. Each code had a structure that corresponded with a particular, highly complex decoding algorithm, which often required the use of dedicated hardware.

One of SpaceX’s oldest rockets launched on a historic 10th flight, carrying the first stack of Starlink satellites into space in more than two months before sticking a landing at sea to cap the successful mission.
The previously-flown Falcon 9 rocket blasted off from Space Launch Complex 4E at Vandenberg Space Force Station at 11:55 p.m. EDT (8:55 p.m. PDT, or 355 Sept. 14 GMT), marking the company’s 22nd launch of the year. It also marked a record 10th flight for this particular first stage booster.
