Artemis.fyi - Real-time tracker for the Artemis II Moon mission

In plain words

Artemis.fyi is a real-time tracker for NASA's Artemis II Moon mission that displays crew activities, Orion spacecraft position, and velocity data. The tool pulls live ephemeris data from JPL's Horizons API and NASA's Deep Space Network feed, updated every five seconds. It was designed to be simpler and more reliable than existing trackers, with a clean interface that works well on mobile devices, showing users exactly what they want to know about the mission's progress.

Real-time and historical telemetry from NASA's Artemis missions, powered by JPL Horizons

In the maker’s words, at launch

There are plenty of Artemis II trackers out there. I looked at a bunch and kept running into the same issues - some had data that didn't look right, it was hard to use on smaller screen, others felt overly complicated for what I actually wanted to know: what's the crew doing, where is Orion, how fast is it going.

  Beautiful 3D ISS tracker with live video and near-realtime clouds2024 · iss.matteason.co.uk · ▲139

  This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
