The Celestial Canopy: An Asymmetric Game in Low Earth Orbit, Chapter 3: Drifting Efficiency Strangulation. When the alarm sounded for the first time at the Starlink command center, the duty staff officer assumed it was a equipment malfunction. The signal strength curve for the Taiwan Strait area on the screen suddenly plummeted like a choked pulse, dropping from a stable 99.7% to 61%. Red warning lights flickered beneath the ceiling. "Check the low-orbit satellite cluster!" the commander's roar cut through the silence. Real-time monitoring footage from the 200-kilometer orbit was pulled up. A silver-gray membrane was slowly unfurling like a jellyfish, its edges glinting with metallic luster under the sunlight. The annotation read: "Phase II of the Celestial Canopy Project - Satellite Civil Sunshade Engineering, Civilian Satellite." The commander jabbed his finger heavily at the screen. "How can its orbital projection area cover the entire Taiwan Strait terrain deployment zone?" No one could answer. Over the next 15 minutes, 200 military drones from Starlink in the Taiwan Strait successively reported signal jumps, a 3.2-second delay when switching to medium-orbit satellites, a 42% signal attenuation when penetrating the membrane, and failed target lock. When the membrane retracted like an umbrella back into the satellite, the signal strength slowly recovered, but the combat system logs had already recorded 317 instruction execution anomalies. At the same time, Lin Ye watched the real-time data at the command center, his lips pressed into a straight line. Zhao Gang's team had frequency windows as precise as a surgeon's scalpel: the military frequency band of 30-40 GHz maintained a penetration rate of 99.5%, allowing their own drones' operational commands to flow unimpeded, while Starlink's reliance on the 12-18 GHz band happened to fall into the membrane's attenuation trap. "The second Celestial Canopy satellite is ready for relay," Lin Ye pressed the communication key. "On schedule, entering the shielding position at 11:03," Zhao Gang's voice came through the earphones, hoarse from staying up late. "Coating stability exceeded expectations, with attenuation rate maintained at 35.2%. The manufacturer just called, wanting to apply for a patent for the new sunscreen material—I suppressed it as a technical confidentiality issue." Lin Ye chuckled softly. The manufacturer still thought those coatings doped with ferrite nanoparticles were only meant to increase sunlight reflectivity by 12%. They had no idea that every roll of membrane they produced was executing another secret mission in the 200-kilometer orbit. The game intensified over the next three months. Starlink tried three countermeasures. First, they lowered their low-orbit satellites to 330 kilometers, attempting to bypass the membrane shielding zone, only to find that the Celestial Canopy satellites could fine-tune their orbits using pulse thrusters, always staying on the beam path. Next, they switched to the transitional frequency band of 18-20 GHz; Zhao Gang's team adjusted the coating formula within 48 hours, stabilizing the attenuation rate at 34%. Finally, they added 12 high-orbit satellites, but as signals traveled an even longer path through the membrane, the attenuation rate rose to 47%. Reports from the Western satellite monitoring center grew increasingly anxious. The transit times of the Celestial Canopy satellites perfectly overlapped with the signal attenuation over the Taiwan Strait, suggesting suspected directional interference capability. But all allegations lacked solid evidence. The public parameters of those membranes met civilian standards, and laboratory tests on the coating composition only showed excellent thermal reflection performance. Six months later, Starlink command received feedback from frontline forces: communication reliability in the Taiwan Strait area had fallen to 57%, and drone units no longer dared to execute high-precision strike missions. Meanwhile, their financial statements showed that the orbital maneuvers and frequency adjustments made to evade the shielding had consumed 43% of the annual budget—enough to launch another 1,200 low-orbit satellites, yet still unable to fill the efficiency gap torn open by the Celestial Canopy satellites. That evening, Lin Ye received a photo from Zhao Gang. In the new exhibition case at the Aerospace Museum, next to a sample of the Celestial Canopy Project's membrane, stood a descriptive plaque reading: "2042: Reduced the temperature of the Yangtze River Delta by 1.8°C." In the corner of the photo, a child stood beside the sample and asked, "Dad, why does this plastic sheet make the Earth cooler?" Lin Ye picked up his phone and sent a brief message to the General Staff Operations Department: "Celestial Canopy operating stably. Recommend purchasing three additional spare satellites under the name of the Celestial Canopy Project Phase III." As the "Sent successfully" prompt appeared, on the 200-kilometer orbit, the third Celestial Canopy satellite was unfurling its membrane. That 8,000-square-kilometer sunshade drifted slowly in the sunlight, like a transparent barrier, silently rewriting the rules of low-Earth space. And on the ground, no one knew the truth of this silent strangulation—except for the number circled in red ink on the orbital parameter table: 200 kilometers.
