24 alternatives to Artemis.fyi - Real-time tracker for the Artemis II Moon mission
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. The best one I found was issinfo.net/artemis, which inspired a lot of the design. So I built my own. The part that was genuinely interesting to me was the data. Turns out anyone can query JPL's Horizons API for full ephemeris data on the Orion spacecraft - position, velocity,…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 2 we have checked on their own sites, 2 of them free or with a free tier.

Made a little Artemis II tracker for anyone else who is unnecessarily invested in this mission: https://artemis-ii-tracker.com/ For those of us who apparently need a dedicated place to monitor this mission instead of behaving like well-adjusted people.

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…

The other day I googled "Where is Artemis" expecting to find a tracker showing me the position, but instead getting results from news articles without live data. I eventually found the NASA tracker (https://www.nasa.gov/missions/artemis-ii/arow/) and https://artemislivetracker.com/, but neither is optimized for mobile and frankly I found them both underwhelming. The domain (whereisartemis.com) was available and I thought "someone should use that", bought the domain and got started. Hopefully, this is something that can be extended for future…

Atlas of Spacefree▲770Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System. As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun. The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits…

Hey 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

Earlier this year, I made a web reader that only showed a list of post titles, author domains, and links. The reader only updated once per day, so I wouldn't feel compelled to keep checking for new posts. I have been using the tool, which I called Artemis, for several months. Every morning, I looked forward to my "morning paper" of blogs I love reading. There are no notifications, read vs. unread states, counts of posts, etc. Only the last seven days of posts are available. The colour scheme is changeable. Dark mode is supported. All popular feed formats are supported. There is no reading…

I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

I built a browser-based simulator of NASA's Artemis II mission — the first crewed lunar flight since Apollo 17. You fly the actual mission profile: launch to parking orbit, raise to High Earth Orbit, fire Trans-Lunar Injection when the Moon is in position, swing behind the Moon, and return to Earth. The physics uses RK4 integration with real Earth and Moon gravity. Have fun experimenting with what happens if you don't time it right!

Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…

Hey HN, This is a follow-up to our original Show HN post, where I launched the first version of MBCompass. https://news.ycombinator.com/item?id=44155741 Since then, I've added several features based on user feedback and community input... I just released v1.1.9 of MBCompass - Minimal, FOSS compass and navigation app. New in this version: - Theme toggling (Dark/Light) controlled via settings - Fix current location arrow visibility - Compass accuracy alerts - Sensor status indicator - Explicit button for showing the GPS current location - Smooth transitions and many more..…
