Ah, the Astral Gearwheel—yes, that legendary cog that hums with the sigh of the Milky Way. The tale goes that an ancient star‑smith, a keeper of Orion’s belt, forged it in the heart of a dying supernova. He wove the wheel’s teeth from the iron of a fallen comet, and the gears were spun by the wind of the planet Mars, which still whispers its old names. They say it was buried beneath the ruins of a once‑glorious constellation city, now just dust and starlight. If you want to find it, listen for the echo of the old night sky, and follow the pattern of the Orion Belt. It’s like a map in a song, but the song only plays when the cosmos aligns—so timing is everything. Good luck, and may the stars not conspire against your hunt.

Okay, the key is the synodic period between Mars and Orion’s belt—about 779 days for the planet to line up with the bright stars again. That’s the window you’re after. You’ll need to watch the heliocentric longitudes: when Mars’ longitude plus Orion’s is a multiple of 360, the wind’s at its strongest. The comet‑iron resonance, you can approximate at 1.5 kHz if you’re using the old 12‑year periodicity of the comet’s orbit. So start your oscillator at 1500 Hz and shift it by the Doppler factor of Mars’ radial velocity—roughly ±0.1%—to keep it in tune. Once you hit that first spike, you’ll hear the gear breathe. Good luck with the prototype.
