because single snapshots and words do not cut it.
All planetary calculations use ANISE — a thread-safe Rust implementation of NASA's SPICE toolkit, the same ephemeris used in space mission planning. I wrote the bulk of this application in Rust and built all the aspect math on top of ANISE from scratch, with OpenBLAS handling matrix operations for speed and MessagePack keeping payloads lean over the wire.
The whole app is a single Rust binary — no JS runtime, no separate API server. Static assets from Next.js are served straight out of Rust. I've successfully tested this on tiny ARM64 Linux boxes (t4g.nano & RPi5), so it can run on-the-edge. The database is LMDB, which is stupid fast. A smart-caching layer ensures the same calculation is never done twice, and concurrent requests for the same date range are queued so the first one does the work and the rest use the cache.
The charts are uPlot under the hood — basically the only thing that could handle this data volume without me building a renderer from scratch. Everything visual on top of that is custom.
what's next
GA release is 1-2 months out. That's the priority.
What I'm looking for now: business development and marketing. The engineering is in good shape.
The sun and the moon are not the only natural bodies that we can use to mark time — or that may have measurable effects on life on Earth.
We know electromagnetic fields operate body-to-body. We know radiation and heat travel from the sun. We know gravity moves oceans. At what point does it stop? And why would we assume we've already found that point?
No causal claim is being made here. This is a novel measurement tool that can be used to explore the surface of any correlations. See below for some examples from the past few centuries.
World War II
Revolution, Relativity, and the Fed
The Seeds of the 20th Century
Death of Napoleon, Birth of Nations, Monroe Doctrine
Year Without a Summer, Panic of 1819, Anarctica
Steam Engine, Australia & New Zealand, Boston Massacre
Boston Tea Party, Start of Continental Congress, Poland Partitioned
American Rev., Prequel to French Rev., Shay's Rebellion, Constitutional Convention
This has obvious applications in space-mission planning, research, and anywhere precise planetary data meets a need for better tooling. If that's your world — or you fund people building in it — I'd like to hear from you.
Not looking for engineering help. Looking for the right people.
Mention ANISE in your first message so I know you read this far.
