Globální satelitní internetová revoluce Starlinku: mobilní pokrytí, tarify a překvapivé novinky pro rok 2025

Klíčová fakta Úvod Starlink je průlomová satelitní internetová síť spuštěná společností SpaceX Elona Muska. Na rozdíl od tradičních satelitních poskytovatelů, kteří používali několik satelitů ve vzdálenosti 36 000 km, Starlink provozuje megakonstelaci tisíců malých satelitů na nízké oběžné dráze Země (~550 km) starlink.com.

  • Securing AI to Benefit from AI: Trust, Identity, and Agentic Defense
    October 21, 2025, 8:44 AM EDT. AI holds promise for strengthening cyber defense, reducing alert fatigue, and scaling analysis beyond human limits. But to realize benefits, organizations must secure the systems powering AI. Without governance, strong identity controls, and visibility into how AI makes decisions, deployments can add risk faster than they reduce it. To truly benefit, defenders must apply the same rigor to AI as to any critical system: establish trust in training data, ensure accountability for actions, and provide oversight of outcomes. Identity security becomes the foundation: every model, script, or autonomous agent is a distinct identity that must be authenticated, authorized, and auditable. With Agentic AI-systems that can act with delegated authority-end-to-end provenance, least privilege, authentication, key rotation, and segmentation are essential. Treat every agent as a first-class identity within IAM to defend smarter, not just faster.
  • UGA Ethics Week Lecture: Responsible AI for the Future of Work with Arun Rai
    October 21, 2025, 8:42 AM EDT. Arun Rai, a veteran scholar in digital innovation, will headline UGA's Ethics Week Lecture on Nov. 7, exploring 'Responsible AI for the Future of Work.' The talk, from 11 a.m. to noon in the Russell Building auditorium, is free and open to the public with registration encouraged. Rai's work centers on responsible AI, workforce transformation, and the intersection of research, education and policy. He is a Regents' Professor at Georgia State University and co-director of the Center for Digital Innovation, leading efforts on human-AI augmentation and fairness. He also leads the Georgia Hub of Pathways for AI Training and Hiring, linking higher education, business and government. The lecture underscores UGA's commitment to an ethical culture and resources for ethics in AI and technology.
  • Orion Installed on SLS as Artemis II Prep Advances During Shutdown
    October 21, 2025, 8:40 AM EDT. NASA says the Orion spacecraft, named Integrity, has been fully attached to the Space Launch System (SLS) inside the Kennedy Space Center's Vehicle Assembly Building (VAB), a key milestone for Artemis II. After rolling to the VAB on Oct. 16 and receiving the launch abort system on top, Orion is set for the early next year circumlunar flight. Acting administrator Sean Duffy announced the update on social media Oct. 20, saying the White House approved continuing Artemis II preparations during the shutdown, with safety-critical work prioritized. NASA's continuity of appropriations plan notes ongoing work to protect Artemis II and III and to maintain supply chains. At Kennedy, 989 of 2,075 civil servants are excepted from furloughs, while Langley has far fewer exemptions.
  • JAXA launches three cubesats from the ISS Kibo module to study space weather
    October 21, 2025, 8:38 AM EDT. JAXA has lofted three cubesats from the ISS using the Kibo module. The trio-YOTSUBA-KULOVER, e-kagaku-1, and BOTAN-were developed by the Kyushu Institute of Technology, the e-kagaku Association, and the Chiba Institute of Technology, respectively. These compact spacecraft exemplify how standardized designs and off-the-shelf components can shorten development cycles and costs. Once deployed, they will monitor auroral activity and broader space weather factors, helping scientists understand how solar activity influences Earth's near-space environment. By focusing on volcanic pumice and other atmospheric interactions, the missions aim to deepen our knowledge of how space weather affects satellites and communications. This set underscores the ongoing push to broaden access to space research through cubesats.
  • Muon Space to Integrate SpaceX Starlink Mini Lasers Into Halo Platform for Real-Time, In-Orbit Connectivity
    October 21, 2025, 8:34 AM EDT. Muon Space announced an agreement with SpaceX's Starlink to integrate its mini laser terminals into Muon's Halo satellite platform, delivering persistent optical connectivity in orbit. The system enables real-time tasking, payload operations, and high-bandwidth data streaming with speeds up to 25 Gbps at distances up to 4,000 km, reducing reliance on ground networks. By linking Muon's satellites to Starlink's global network, customers gain continuous, on-orbit access to data and constellations, enabling new business models where spacecraft act as always-on nodes with Earth-based cloud-like responsiveness. Executives call the move a sea change in space ops, turning Halo into an active node on Starlink's in-space laser mesh and delivering ultra-low latency to terrestrial points of presence.
