The International Space Station experiences constant, low-level aerodynamic drag, which causes its orbit to steadily decay. Electrodynamic tethers had long been proposed to generate thrust by using solar power to drive electrical current (collected from the ionosphere in this animation) against an induced voltage, adding orbital energy to compensate for that which was lost to aero drag.

STARLINK IS RUNNING EARTH’S LARGEST SERVER… IN ORBIT While everyone else is bragging about data centers on the ground, SpaceX quietly put 9,000 solar-powered computers in space and called it a constellation! Orbital Math: •⁠ ⁠Starlink sits at over 9,000+ active satellites after the latest batch •⁠ ⁠The entire rest of Earth manages roughly 3,000 to 4,000 combined •⁠ ⁠Each Starlink unit is a solar-powered network node with onboard compute •⁠ ⁠SpaceX now operates around 75 % of all active satellites in orbit At this rate Earth’s “space industry” is basically Starlink plus supporting characters!

🚨 SPACEX IS ABOUT TO TEST A RADICALLY DIFFERENT KIND OF SPACECRAFT AND IT COULD UPEND THE ENTIRE ORBITAL MANUFACTURING INDUSTRY. On Tuesday, SpaceX plans to fly the first prototype of Starfall, a flat, disk-shaped reentry capsule designed to return up to 1,000 kilograms of cargo from orbit in a single flight. That’s roughly 30 times more payload capacity than current commercial return vehicles (like those from Varda Space Industries). It’s not a scaled-down Dragon it’s a completely different approach: no onboard deorbit engine, a wide flat disk geometry, and Starlink terminals mounted to maintain communication through the plasma blackout during reentry. Why this matters: • Current orbital manufacturing companies are limited to returning only dozens of kilograms per mission • Starfall’s design could make large-scale commercial production in space economically viable for the first time • SpaceX would be directly competing with companies (like Varda) that currently pay SpaceX to launch their capsules • Successfully testing Starlink through reentry plasma would be a major technical win with applications across SpaceX’s vehicles The deeper implication: SpaceX is quietly expanding its vertical integration. They already dominate launch. Now they’re moving into the return leg of the orbital manufacturing supply chain the part that has been the biggest bottleneck for companies trying to make products in microgravity and bring them back to Earth. If Starfall works at scale, it doesn’t just give SpaceX another revenue stream. It gives them significant control over the economics of an entire emerging industry. The disk shape and high-capacity design suggest they’re thinking about high-cadence, lower-cost returns rather than the traditional high-value, low-volume approach. This is classic SpaceX: take an existing problem (expensive, low-capacity return from orbit), apply first-principles thinking to the vehicle design, and try to make it dramatically cheaper and higher volume. How do you think this move into orbital return changes the competitive landscape for companies trying to build businesses in space manufacturing? Follow for more analysis on SpaceX’s expanding role across the space economy.

🚨 BREAKING: Starcloud just turned Starlink’s laser network into the backbone for orbital AI data centers. A company called Starcloud has ordered 50+ Starlink Mini Laser terminals to equip 25+ future satellites. Not ground stations. Not fiber cables. Direct laser-linked computing nodes in orbit plugged straight into SpaceX’s space-based optical mesh. This is the sci-fi future arriving now: Orbital cloud computing AI servers floating in space Powered by 24/7 sunlight Connected globally at light speed via Starlink lasers The insane part: Starcloud says its satellites will eventually handle full AI inference and training workloads directly in orbit. Data won’t always need to come back to Earth to be processed. The advantages are massive: • Unlimited solar energy (no grid limits) • Zero land or water constraints • Passive radiative cooling in vacuum • Instant global relay with zero terrestrial bottlenecks • Near real-time Earth observation analysis Their first major spacecraft (Starcloud-3) is designed for 200 kilowatts in orbit a full-on space-based data center node, not just a satellite. And here’s the bigger picture: SpaceX has filed plans for up to ONE MILLION orbital data centers of its own. Read that again. We may be watching the birth of the first true space-based computing infrastructure layer for civilization. The internet already left the ground. Now AI might be next. What happens when the cloud literally moves into space? Follow for more frontier physics and future technology.

The countdown has begun! The upcoming SpaceX Transporter-12 mission, in collaboration with D-Orbit will carry four more of our Connecta IoT satellites into orbit. These additional satellites will unlock the high-capacity and decrease the revisit times, propelling our commercial services to new horizons. As we prepare to launch the next phase of our Connecta IoT Network, this mission marks a giant leap in our journey. Stay tuned and join us as we continue to redefine what's possible in space! #WeArePlanS #PlanS #Connecta #countdown

The Chinese Space Station will have 3 orbital conjunctions with the ISS this weekend. It will be a historic first photo opportunity. Here is a video of one conjunction over Africa. At the right solar angles, visibility may be favorable. But they will have to snap fast!

STARMIND sounds like something from a sci-fi movie. Naturally, SpaceX set its mind to make it real. Starlink connects the world from space. STARMIND would run AI from space. Solar-powered orbital compute, laser-linked satellites, and eventually a massive xAI network above Earth. Starlink's wi-fi connection went into orbit first. Now the xAI brain wants a launch window.

seeing the earth from space is absolutely life changing. my mission, Inspiration4, was the first all-civilian orbital space mission. it was a new beginning — opening up space exploration to more and more people. I hope that you all will be able to experience these views for yourself someday, but if you prefer staying on Earth, please enjoy my videos 🚀
