In plain words
Satlas is a real-time 3D orbit tracker that monitors over 31,000 satellites, space objects, and debris. Users can query it in plain English through an AI agent to find when satellites pass overhead, receiving precise timing, elevation angles, and visibility conditions. The tool includes pass visibility scoring, category filters, country-specific tracking, and a public REST API. It is designed for space enthusiasts, researchers, and anyone curious about orbital mechanics. The platform is fully open source with no authentication required.

From the sources
Satlas is a real-time 3D orbit tracker for 31,000+ objects, satellites, and debris, queryable in plain English via an AI agent. Ask "when does the ISS pass over Melbourne?" and it runs actual orbital mechanics, tells you the time, max elevation, and whether the sky will be dark enough to see it. Click any country to see every satellite overhead right now. Features: pass visibility scoring, category filters, country mode, and a public REST API at satlas.app/docs. No auth. Fully open source.

Orbit – AR satellite tracker, watch 15k+ objectsJul 2026 · nagylukas.github.io · ▲89Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have. This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
