Impulse Space Miras Approach Within 200 Meters in Orbital Rendezvous Demonstration
Two Impulse Space Mira orbital transfer vehicles approached within approximately 200 meters of each other in low Earth orbit during a July 2026 rendezvous and proximity operations demonstration, the California-based company announced September 8. The maneuver involved spacecraft launched on the LEO Express 2 and LEO Express 3 missions and demonstrated controlled orbit matching, close…

China’s First Open Shared TT&C Platform for Commercial Space Begins Operations in Beijing
China’s first open shared platform for commercial space tracking, telemetry and command (TT&C) services officially began operations Aug. 19 in Beijing, supporting the full measurement and control process for the launch of a Honghu-03 satellite and the recovery of a reusable rocket booster. The Beijing Rocket Street Commercial Space Intelligent TT&C Center, located in Beijing…

Project-S Emerges from Stealth With Funding for Space-Based Radar, Targets October Demonstration
Munich-based Project-S publicly emerged from stealth on September 2, 2026, announcing multi-million-euro backing to develop space-based radar for detecting and tracking orbital debris. The startup plans to launch its first radar demonstrator aboard a SpaceX Transporter rideshare mission in October, an initial step toward providing satellite operators with better information on small objects that threaten…

Starlink Ephemeris Data Enable First Real-World Tomographic Map of Thermospheric Density
Researchers at Kyoto University have demonstrated a new way to observe Earth’s upper atmosphere by transforming publicly available Starlink orbital data into the first tomographic map of thermospheric density derived from real satellite measurements rather than simulations. The study, published in *Earth, Planets and Space*, used orbital ephemeris data from approximately 1,200 Starlink satellites operating…

NASA Extends Starling Mission After Demonstrating GPS-Free Autonomous Satellite Navigation
NASA has extended its Starling spacecraft swarm mission through at least 2028 after a successful in-orbit demonstration of a navigation system that allows satellites to determine their position without relying on the Global Positioning System (GPS), marking a significant step toward greater spacecraft autonomy for future lunar and deep-space operations. The technology, known as Fast…

As Satellites Multiply, Does Space Need “Traffic Police”? A Survey of China’s Space Traffic Management Companies
Suppose a satellite receives an alert in the early hours of the morning: in 36 hours, it may pass dangerously close to a defunct rocket fragment. The predicted miss distance is only a few hundred meters. That sounds alarming, but operators cannot immediately fire the thrusters and change orbit. They must first determine whether the…

China’s New Space Contest Will Be Fought With Commercial Satellites
Over the past decade, the commercial space industry has transformed satellites from assets reserved for national-level missions into industrial products that can be mass-produced and deployed on demand. As thousands of low-Earth-orbit broadband, remote-sensing and navigation satellites form constellations, space is taking on the characteristics of infrastructure for the first time—continuously providing connectivity, observation and…

The New Space Race Will Be Won by Commercial Satellites
Over the past decade, commercial space has transformed satellites from “national-level missions” into industrial products that can be mass-produced and deployed on demand. As thousands of low-Earth orbit broadband, remote-sensing and navigation satellites form interconnected constellations, space has acquired the characteristics of infrastructure for the first time. It can continuously provide connectivity, observation and positioning…
