At Bletchley Park in the 1940s, Alan Turing and colleagues decrypted Enigma messages, providing ULTRA intelligence that aided Allied victory. The United States began launching military communications satellites in the 1960s, and by 1982 the second- and third-generation DSCS satellites offered nuclear-hardened, anti-jamming, high-data-rate links worldwide. In 1976, Diffie–Hellman introduced public-key cryptography, and DES was…

During Operation Rising Lion in mid-June 2025, Israel ingested more than 12,000 fresh satellite images during the shooting phase from the Ofek optical and SAR constellation and commercial vendors, with tens of millions of square kilometers imaged day and night. The domestic space stack centers on Ofek-16 (optical) and Ofek-13 SAR, delivering 0.5 m visual…

Starlink has over 7,500 active LEO satellites as of 2025 at about 550 km altitude, with plans to up to 42,000, uses Ku/Ka bands and laser inter-satellite links, and is piloting Direct-to-Cell IoT connectivity with latency around 20–50 ms. OneWeb has approximately 600 active satellites out of 648 in its first-generation network in near-polar orbits…

In June 2025, Wu Jian of Peking University of Posts & Telecom and Liu Chao of the Chinese Academy of Sciences directed a 2-watt laser from 36,000 km in geostationary orbit to a ground station, achieving 1 Gbps. The test claimed the 1 Gbps downlink is five times faster than Starlink downlinks, per the South…

The CORONA (Discoverer) program operated from 1959 to 1972 as the United States’ first photo-reconnaissance satellite program, with Discoverer XIV achieving the first mid-air film recovery in August 1960. KH-11 KENNEN (CRYSTAL), first launched in 1976, introduced electro-optical digital imaging with about 15 cm per-pixel resolution, and a 2019 declassified image from USA-224 reportedly achieved…

Satellite internet data travels from your dish to a satellite, then to a gateway and onto the internet, with traditional GEO orbits at about 35,786 km and newer systems like SpaceX Starlink using low Earth orbit swarms and inter-satellite laser links. Geostationary (GEO) latency is roughly 500–700 ms for a round trip, while Starlink’s low…
