Released ASTRA-1 3B on Ollama — a purpose-built space science model
ASTRA-1 3B is a model purpose-built for space physics and aerospace engineering. It runs the Cosmica persona and is focused entirely on space science — not a general assistant.
Some things worth noting from testing:
— Handles conceptual space science well — black holes, orbital mechanics, stellar physics, general relativity
— Does actual math when asked — escape velocity derivations, time dilation near black holes, angular momentum conservation
— Deflects off-topic questions cleanly instead of hallucinating an answer
— Says "we don't know" on genuinely open questions like dark matter composition or what's inside a neutron star core
It's a 3B so it has limits — complex multi-step calculations aren't its strong suit, but for conceptual space science it holds up well at this size.

Feedback welcome — especially from anyone who pushes it on harder questions.
Ad astra per aspera.
