SpaceX’s Starlink internet shows fast speeds during early tests, capable of gaming and streaming

Posted by in categories: Elon Musk, entertainment, internet, satellites

SpaceX gave an update on early tests of its Starlink satellite internet network, which showed speeds capable of playing online video games and streaming movies.

Starlink is the ambitious plan by Elon Musk’s company to build an interconnected network of about 12,000 small satellites in low Earth orbit. To date, SpaceX has launched about 650 of its version 1.0 satellites and is currently building a system of ground stations and user terminals to connect consumers directly to its network.

The company confirmed during the webcast of its latest launch on Monday that employees have been testing Starlink’s latency and download speeds, key measures for an internet service provider. SpaceX senior certification engineer Kate Tice said that the initial results of those tests “have been good.”

Watch: This video is narrated in Spanish, my native language, but I added comprehensive subtitles in English

Posted by in categories: internet, life extension, transhumanism

Actually, the predominant language of the website is English, but even me being bilingual, I felt more comfortable delivering the narrative in my native language.

In the video, I give a thorough overview of the content and organization of my website Transhumanplus.com. It has a huge amount of information, growing constantly, on the transhumanist movement, emerging technologies in general, and very specially, on the longevity, rejuvenation and life extension field.

Memory in a metal, enabled by quantum geometry

Posted by in categories: information science, internet, quantum physics, robotics/AI

The emergence of artificial intelligence and machine learning techniques is changing the world dramatically with novel applications such as internet of things, autonomous vehicles, real-time imaging processing and big data analytics in healthcare. In 2020, the global data volume is estimated to reach 44 Zettabytes, and it will continue to grow beyond the current capacity of computing and storage devices. At the same time, the related electricity consumption will increase 15 times by 2030, swallowing 8% of the global energy demand. Therefore, reducing energy consumption and increasing speed of information storage technology is in urgent need.

Berkeley researchers led by HKU President Professor Xiang Zhang when he was in Berkeley, in collaboration with Professor Aaron Lindenberg’s team at Stanford University, invented a new data storage method: They make odd numbered layers slide relative to even-number layers in tungsten ditelluride, which is only 3nm thick. The arrangement of these atomic layers represents 0 and 1 for data storage. These researchers creatively make use of quantum geometry: Berry curvature, to read information out. Therefore, this material platform works ideally for memory, with independent ‘write’ and ‘read’ operation. The using this novel data storage method can be over 100 times less than the traditional method.

This work is a conceptual innovation for non-volatile storage types and can potentially bring technological revolution. For the first time, the researchers prove that two-dimensional semi-metals, going beyond traditional silicon material, can be used for information storage and reading. This work was published in the latest issue of the journal Nature Physics. Compared with the existing non-volatile (NVW) memory, this new material platform is expected to increase speed by two orders and decrease energy cost by three orders, and it can greatly facilitate the realization of emerging in-memory computing and neural network computing.

Two-photon comb with wavelength conversion and 20-km distribution for quantum communication

Posted by in categories: internet, quantum physics

Quantum technologies have seen a remarkable development in recent years and are expected to contribute to quantum internet technologies. The authors present an experimental implementation over commercial telecom fibres of a two-photon comb source for quantum communications with long coherence times and narrow bandwidth, which is used in a 20 km distribution experiment to show the presence of remote two-photon correlations.

Gravity wave insights from internet-beaming balloons

Posted by in categories: climatology, internet, physics

Giant balloons launched into the stratosphere to beam internet service to Earth have helped scientists measure tiny ripples in our upper atmosphere, uncovering patterns that could improve weather forecasts and climate models.

The ripples, known as waves or buoyancy waves, emerge when blobs of air are forced upward and then pulled down by gravity. Imagine a parcel of air that rushes over mountains, plunges toward cool valleys, shuttles across land and sea and ricochets off growing storms, bobbing up and down between layers of stable atmosphere in a great tug of war between buoyancy and gravity. A single wave can travel for thousands of miles, carrying momentum and heat along the way.

Although lesser known than —undulations in the fabric of space-time— are ubiquitous and powerful, said Stanford University atmospheric scientist Aditi Sheshadri, senior author of a new study detailing changes in high-frequency gravity waves across seasons and latitudes. They cause some of the turbulence felt on airplanes flying in and have a strong influence on how storms play out at ground level.

Following schedule adjustment, Starlink now set to launch September 3

Posted by in categories: internet, satellites

SpaceX has officially shifted Tuesday’s planned launch of 60 Starlink internet satellites from pad 39A at NASA’s Kennedy Space Center in Florida. Representatives from SpaceX wrote on Twitter, “Now targeting Thursday, September 3 at 8:46 a.m. EDT for launch of Starlink from Launch Complex 39A, pending Range acceptance — team is using additional time for data review.” Prior to the flight schedule change being made and published on Monday, members of the media had been out at the remote camera setup event at LC 39A. It is unclear whether there will be any need for additional.

This is the second scrub for this mission in as many days; Sunday’s planned launch, the first in what was planned to be a back-to-back double launch day, pushed to Tuesday September 1 due to inclement weather during pre-flight operations.

Beyond this mission, Starlink 12 and Starlink 13 are currently scheduled for September 12 and 13 respectively, launch times TBD.
