Optical Inter-Satellite Link
21 in indexFree-space optical links between satellites, replacing RF cross-links with higher-bandwidth, harder-to-jam laser communications.
Optical Inter-Satellite Links (OISL) use laser communications between spacecraft instead of RF. The trade: dramatically higher data rates (multi-Gbps to Tbps), tight beam steering (which is both a security feature and an acquisition challenge), and no spectrum coordination required.
OISL is what makes a constellation a network. Without it, every satellite needs ground gateways for backhaul. With it, traffic routes in space, latency drops, and ground infrastructure simplifies. SDA's Tranche 1/2, Starlink v2, and most modern defense architectures all assume OISL.
- Backhaul in LEO comms constellations
- Cross-domain (LEO-GEO, LEO-Lunar) data relay
- Tactical defense networks (SDA PWSA)

Approximately 10,000 years ago, teenagers in what is now western Sweden chewed wads of birch bark pitch and spat them out, and the saliva preserved in the wads contained enough human and microbial DNA that scientists have since sequenced the chewers’ complete genomes, identified the food they had eaten that day, and detected the bacterial signature of their gum disease.
The site is called Huseby Klev. It sits on the island of Orust on the western coast of Sweden, about an hour’s drive north of Gothenburg. Approximately ten thousand years ago, when sea levels were higher and the coastline ran further inland, Huseby Klev was a coastal fishing camp at the end of a narrow […] The post Approximately 10,000 years ago, teenagers in what is now western Sweden chewed wads of birch bark pitch and spat them out, and the saliva preserved in the wads contained enough human and microbial DNA that scientists have since sequenced the chewers’ complete genomes, identified the food they had eaten that day, and detected the bacterial signature of their gum disease. appeared first on Space Daily.
The longest-lived people on Earth do not run marathons, lift weights, or follow structured exercise plans — instead, they live in places where physical movement is built into daily life through walking, gardening, and the simple geography of hilly terrain — meaning the most effective anti-aging routine ever identified by researchers may be one that doesn’t feel like a routine at all
The 75-year-old Sardinian shepherd Tonino Tola, profiled by National Geographic during Dan Buettner’s original Blue Zones research in the early 2000s, walked at least five miles every day along the rugged mountain trails of his island’s interior. He did not walk for exercise. He walked because his sheep needed tending, his garden needed weeding, his […] The post The longest-lived people on Earth do not run marathons, lift weights, or follow structured exercise plans — instead, they live in places where physical movement is built into daily life through walking, gardening, and the simple geography of hilly terrain — meaning the most effective anti-aging routine ever identified by researchers may be one that doesn’t feel like a routine at all appeared first on Space Daily.
