SpaceX CEO Elon Musk has revealed the first technical details about the company’s next-generation Starlink ‘Gen2’ satellite design, confirming that it will far outmatch the current generation of satellites by almost every measure.

Speaking in an onsite interview and Starbase tour with YouTuber Tim Dodd (The Everyday Astronaut), Musk – largely unprovoked – revealed that SpaceX has already built at least one functional Starlink Gen2/V2.0 satellite prototype and shipped it to the South Texas Starship factory, where it is currently being stored. More importantly, Musk also provided the first direct specifications for the next-generation spacecraft, stating that each Starlink V2.0 satellite will weigh about 1.25 tons (~2750 lb), measure about seven meters (~23 ft) long, and be almost an order of magnitude more capable than the “Starlink 1” satellites they’ll ultimately supersede.

Almost ten months after SpaceX first revealed its updated plans for a next-generation, 30,000-satellite constellation, those details have confirmed a few key points of speculation about the future of Starlink.

China has to have the capability to identify and destroy SpaceX’s Starlink satellites, according to Chinese military experts in a report released in April. The research, headed by Ren Yuanzhen of the Beijing Institute of Tracking and Telecommunications, was published in the Chinese peer-reviewed journal Modern Defence Technology. The publication inexplicably disappeared from the online version of The South China Morning Post after The South China Morning Post reported on its contents.

David Cowhig, a former US ambassador, was able to complete the translation of the document before it vanished, which allowed him to uncover a number of preventative steps that were suggested to be taken against Starlink. According to the study, China has to “use a mix of soft and hard kill measures to disrupt the operating system of the constellation and deactivate part of the Starlink satellites.”

The mission, called OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing-1), will send a robotic spacecraft equipped with robotic arms and all the tools and equipment needed to fix, refuel, or extend satellite lifespans, even if those satellites were not designed to be serviced on-orbit.

A small spacecraft will wade the gravitational tides between Earth and the Moon.

SpaceX informed the Federal Communications Commission (FCC) it surpassed 400,000 Starlink Internet subscribers across 36 countries. The company had a private conference presentation with FCC representatives on May 19 about using the 12GHz band “for providing next-generation satellite services to Americans,” including to use Starlink broadband satellite service on moving vehicles.

An outline of the presentation was submitted as a public filing to the Commission where it states the new subscriber count and a list of how Starlink has been useful; a screenshot of the document is shown below. SpaceX doubled the amount of Starlink subscribers in just a couple months. SpaceX announced its Starlink division had 250,000 subscribers in February.

SpaceX’s FCC presentation says the Starlink service is active in 48 U.S. states. Besides the United States, Starlink is now available in portions of: Canada, United Kingdom, Germany, New Zealand, Australia, Austria, Netherlands, Belgium, Ireland, Denmark, Chile, Portugal, Switzerland, Poland, Italy, Czech Republic, Sweden, Mexico, Croatia, Lithuania, Spain, Slovakia, Slovenia, Brazil, Bulgaria, Romania, Greece, Luxembourg, Latvia, Tonga, Hungary, and Ukraine. SpaceX plans to expand service to Africa, Asia, and the Middle East in 2023. The company recently released an interactive Starlink Coverage Map which shows where the internet service is “available” and on a “waitlist” by simply typing an address.

War feels ‘a hundred times more irrational’ when viewed from space.

Satellite images taken from space have been vital in reporting on the war in Ukraine. They have even helped to debunk disinformation that has spread since the start of Russia’s invasion in late February.

While satellites — such as those used by Maxar Technologies to help document the war — are equipped with powerful cameras that can zoom into vast regions, it turns out the conflict is also visible to the naked eye from orbital space.

Volcanic eruptions remind us that the inside of our planet isn’t exactly tranquil, but there’s plenty of completely unknown stuff happening beneath our feet.

ESA’s Swarm satellite mission has detected a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years.

The finding could help us to understand more about Earth’s magnetic field, without which life as we know it could not exist.

The study was led by Ren Yuanzhen, a researcher with the Beijing Institute of Tracking and Telecommunications, under the PLA’s Strategic Support Force. Coauthors included several senior scientists in China’s defense industry.

Ren and his colleagues could not immediately be reached for comment and it is uncertain to what extent their view represents an official stance of the Chinese military or government.

“A combination of soft and hard kill methods should be adopted to make some Starlink satellites lose their functions and destroy the constellation’s operating system,” said the paper, published in the domestic, peer-reviewed journal Modern Defense Technology.
