hey HN, i built this because i wanted to know what had actually photographed my street.

type in any place and it finds every satellite that passed over it in the last 7 days (SGP4 on the CelesTrak catalog, runs in your browser in about half a second), then pulls the real Sentinel-2 / Landsat / NASA images from those passes.

some fun bits: - the pass search can't skip a pass. checked it against a brute force on poles, the antimeridian and tiny swaths: 0 missed - all ~17k objects in orbit are drawn on the GPU, solving Kepler's equation every frame - Sentinel-2 timestamps are often 5-10 min off from when the sat actually crosses your spot, which was a fun one to figure out

it only says "watched" if a real image exists, and it doesn't store your location.

would love feedback, especially on what data sources to add

This is not only a very cool idea, but also fantastic execution! Great work and very neat!

I don't say this lightly: This may be the best combination of style and substance I have ever seen.

Um, wow. Amazing UI.

This photo of the SF Bay this morning is a great representation of the fog that settles in over the area:

This is very cool, and a bit creepy too, but mostly cool

Really liked the UX, even on a small phone screen it was easy to use. I enjoyed the big typing cursor, it was a unique surprise (almost 100% of text form inputs have either a very small vertical line cursor, or nothing at all - the big cursor feels refreshing)

Can you get high res images, or are they typically not made public?

Very cool tool

Very cool. Was this inspired by the latest season of cyberpunk? In case you and Capri need to escape onto a satellite. XD

This is great for planning backpacking trips. I have been using Copernicus but you have a lot more and it's much easier to access. Very nice!

I have seen a lot of sites with satellites’ overviews… I work in geospatial.

This site is really good one as you can see exact image taken by a satellite.

Well done.

Pretty damn cool and super smooth. Thanks op!

Great user interface - animations are such a nice touch.

That looks really nice. I especially like the view showing the satellite flying overhead and the line marking the scanned area.

Love the fly overs, and the interface. Just beautiful.

Awesome page. Thanks for building.
