China begins assembling its supercomputer in space
China has launched the first 12 satellites of a planned 2,800-strong orbital supercomputer satellite network, reports Space News. The satellites, created by the company ADA Space, Zhijiang Laboratory, and Neijang High-Tech Zone, will be able to process the data they collect themselves, rather than relying on terrestrial stations to do it for them, according to ADA Space’s announcement (machine-translated).
The satellites are part of ADA Space’s “Star Compute” program and the first of what it calls the “Three-Body Computing Constellation,” the company writes. Each of the 12 satellites has an onboard 8-billion parameter AI model and is capable of 744 tera operations per second (TOPS) — a measure of their AI processing grunt — and, collectively, ADA Space says they can manage 5 peta operations per second, or POPS. That’s quite a bit more than, say, the 40 TOPS required for a Microsoft Copilot PC. The eventual goal is to have a network of thousands of satellites that achieve 1,000 POPs, according to the Chinese government.
With announcements like this, you begin to understand that, by comparison, Americans are not a serious people. We are too busy fighting with each other while China assumes the mantle of the lone technological superpower.
Space Force warns of Chinese satellites ‘dogfighting’
China has practiced co-ordinated satellite maneuvers in space that resemble aerial combat, according to a US Space Force General.
Speaking on Tuesday at the McAleese Defense Programs Conference in Washington, the vice chief of space operations General Michael Guetlein said the US is preparing to develop capabilities for off-planet warfare. Space Force needs to guarantee “space superiority,” over China, Russia, and other nations, he opined.
That status is necessary because China has already launched a refuelling station in geosynchronous equatorial orbit to service its growing satellite fleet.
Now it’s used some of its orbiting assets in what look like offensive drills.
“We observed five objects in space moving in and out and around each other in synchrony and in control,” Guetlein said. “That’s what we call dogfighting in space - they are practicing tactics, techniques and procedures to do in-orbit space operations from one satellite to another.”
This is not the future I wanted to live in, but here we are.
The United States needs a backup positioning system for GPS and it needs it yesterday.
Space junk could have a transcendent, purposeful afterlife
The idea of a skyhook has been under study for half a century now; it would take the form of a long and strong tether extending from a base station on Earth’s surface into space. The other end of the tether, a counterweight like Envisat, would remain in orbit around Earth. As the tether rotates, the counterweight generates centrifugal force, creating tension in the tether. Spacecrafts and payloads can then be attached to the tether and released into space when they reach the desired velocity, essentially ‘hooking’ them into orbit. The counterweight’s substantial mass and its fixed position in space would act as the pivot point for the entire system, allowing the tether to maintain tension and transfer momentum. Depending on the tether’s length, materials and the specific rotational characteristics of the skyhook, the momentum it imparts to payloads could potentially extend their reach beyond Earth’s orbit to reach other celestial bodies. Further into the future, skyhooks could span across three celestial bodies – Earth, the Moon and Mars – forming a seamless interconnected network.
Airbus Launches Device to Prevent Dead Satellites from Tumbling
Detumbler is a magnetic damping device that’s meant to be attached to a satellite that’s nearing the end of its life, according to Airbus. Weighing around 100 grams, Detumbler has a central rotor wheel and magnets that interact with the Earth’s magnetic field, which prevents unwanted motion when defunct satellites start to tumble. The device is designed to behave like a compass when the satellite is flying normally in its orbit, aligning with Earth’s magnetic field. If it begins to tumble, however, the movement of the rotor will trigger eddy currents (loops of electrical current within conductors induced by a changing magnetic field) and cause friction to slow down the motion.
Awesome.

SpaceX Starlink satellites had to make 25,000 collision-avoidance maneuvers in just 6 months — and it will only get worse
Lewis expects that, unless regulators cap the number of satellites in orbit, collisions will soon become a regular part of the space business. Such collisions would lead to rapid growth in the amount of space debris fragments that are completely out of control, which would lead to more and more collisions. The end point of this process might be the Kessler Syndrome, a scenario predicted in the late 1970s by former NASA physicist Donald Kessler. Depicted in the 2013 Oscar-winning movie “Gravity,” the Kessler Syndrome is an unstoppable cascade of collisions that might render parts of the orbital environment completely unusable.
Modernity is untenable.
