I recommend https://issinfo.net/artemis over the surge of vibe coded Artemis II trackers. Seen two others so far and they've all had major inaccuracies either regarding trajectory, current distance, or current mission state. One even said the remaining mission time was over 400 days. They all obviously used Claude Code.

Just to be clear one glance and I can tell issinfo.net also used claude code
Great sense of scale, lovely to see the Moon apparently a long way from the "intercept" point, and it seems "accurate enough".

Thanks - it's very nice to have a progress bar that you can scrub through to see where and when they have been and will be later in the mission.

I did not use claude code, but codex, and I am fetching space weather from NOAA SWPc, trajectory, distance, speed, and comms delay are computed from NASA's published Artemis II mission plan parameters, not pulled live from NASA telemetry. Also, the current discrepancy is likely caused by the orbital phase and reference model being used. tracker shows about 192,000 km, while NASA's AROW shows about 80,000 miles, which is roughly 129,000 km. it is off by around 60,000 km.
difference can happen because the spacecraft is in a elliptical orbit and different trackers may be using different assumptions, interpolation methods,... or reference points for the trajectory

To me, what's super interesting about this is the fact that my brain instantly recognized it's AI coded (not sure why, it might be the spacing, the font, the text glow, etc.).

Developers and their customers mostly gave up design many years ago and used frameworks like Bootstrap because they are good enough, they are cheap to create, they increase speed to deliver with no external designer in the loop, etc. That made many sites look alike. AI designed web sites are the next natural step.

The First thought that came to mind was It's AI coded. Maybe it's because they follow a similar design pattern. Or maybe we have some supernatural powers
This sort of bluish dark mode with monospace fonts. Similar accent colors. Not sure where it got this style from.

What's even more interesting is that data is completely off compared to official sources, and the author doesn't even have the decency and self-reflection of checking if their slop is at all accurate before posting it to the HN front page.
Vibe coders, like the eggman himself, are philosophical zombies.

I think it's because the UI sucks, like really bad. Why is there a CRT-type line in the background going down constantly. The mission timeline has weird colors that make no sense. Some graphs don't even fit their parent element. And so on.
I don't care if its vibe-coded but if you looked at this and thought "yeah that looks good", it only shows how bad you are at UI.
These types of interfaces are cool if you're like 12

It says the distance from Earth right now is 154,000km, but the other trackers, including NASA, say 30,000km (numbers rounded). The velocity is different as well, 7km/s vs NASA's 4km/s.

It has "Distance From Earth" at 44,096 km (converted from miles...,) as opposed to 158,000 km. So yes, far off.

NASA uses Imperial units (well, unless the it's the Mars Climate Orbiter). Can we get a version that follows the units they are using with their public feeds?

Great UI, but inaccurate slop. Couldn’t this have been validated against NASA’s site? Can we get this off the front page if the author can’t even be bothered to do that?

This has always been a peeve of mine, but the lack of scale diagrams in coverage of this is maddening. We know what the Earth and the Moon look like, there is no need to make them 20 times bigger. Surely the point of these diagrams is to show the unbelievable scale of the journey. I'm yet to see one this news cycle, from NASA or anyone else
zamadatix 22 hours ago [-]
In defense of the given approach:
False scale gives a direct way to see which body is which and where the craft is between them without having to work it out backwards from the rest of the context (while real scale makes both sides just looks like dots on typical sized screens and you need to know/read the rest before you can figure out which is which otherwise).
Combine that with "the scale of the Earth is already too large to comprehend accurately anyways" and defaulting to real scale doesn't really add as much as one might think to the experience anyways.
The actual Earth and Moon are still not nearly to scale though!

zamadatix 22 hours ago [-]
I'll be the guy that talks down about Show HN becoming a place to post the thing you just vibe coded then because they didn't even bother to check the accuracy of the result - the numbers it provides about the mission are waaay off from reality right now, it just looks fancy.
I'm not necessarily against people sharing AI generated projects but there almost needs to be an [AI] tag if they do because it's really crashing the excitement of seeing a Show HN post where the assumption is this is something someone has been working hard on and is proud to show it off rather than something they just got out of Claude or whatever after a few prompts.
My take: If you didn't spend at least 24 hours of your own time (i.e. not munging with what the LLM is outputting but dedicated time for your own edits/testing) then it shouldn't qualify as a normal Show HN.

The closest they get to the moon is about 8000km/5000 miles above the surface over the far side
The trajectory depicted has them hitting the moon; it should instead show them passing 2+ lunar diameters behind the moon.

BTW, 90% of the comments being about whether this was made with AI or not (and personal opinions on it) is much MUCH worse than it being made with AI. The lack of downvotes for submissions is not an invitation to bring negativity to the comments; if the submission doesn't provide value to you, just move along. Make another post with your opinions on AI and see how many care to read it.
Bless! Absolutely love this, and an absolutely no disrespect, this is vibe code goodness! These are the kinds of things I have an absolute ball building, usually when I’m sitting on the couch at the end of the day duel screening.
What’s the data source? Assuming NASA being NASA they have a public API for the mission?
