+# NewSpace Market MRD
+
+Typed, datasheet-sourced specifications for **2,486 spacecraft flight hardware products
+across 24 categories** — reaction wheels, star trackers, propulsion, radios, antennas,
+structures, ground stations and more — with **19,011 values, each citing the vendor
+datasheet page it came from**.
+
+The dataset exists because component selection is a task where a language model must not
+improvise: a wheel that cannot take a 12 V bus is not a "close enough" answer. Three rules
+make the data safe to compute on.
+
+* **Nothing is guessed.** A missing property means the vendor does not publish it. The
+  record is absent rather than filled with a typical value.
+* **Conditions are kept apart.** Idle, steady-state and peak power are separate rows, each
+  with its measurement condition. They are never averaged into one number.
+* **Every value is traceable.** Source file and page, plus a confidence level: `L0`
+  machine-extracted, `L1` verified by a human against the vendor datasheet.
+
+## Files
+
+| File | One row is | Rows |
+|------|------------|------|
+| `mrd-values.csv` | one measured value | 19,011 |
+| `mrd-products.csv` | one product | 2,486 |
+| `mrd-properties.csv` | one property in the dictionary | 111 |
+| `mrd-full.json` | everything, nested by product | — |
+
+### Columns of `mrd-values.csv`
+
+| Column | Meaning |
+|--------|---------|
+| `product_id`, `product_name`, `category` | which item the value belongs to |
+| `prop` | property key; see `mrd-properties.csv` for its label and canonical unit |
+| `num`, `num_max` | the figure; both are filled when the vendor published a range |
+| `text` | for non-numeric properties: interface, band, material, heritage |
+| `unit` | canonical unit, converted **by code** (kg→g, dBm→W, psi→bar, tf→mN) |
+| `bound` | `min`, `typical`, `max`, `range`, `nominal` — which end of the spec this is |
+| `condition` | measurement condition as printed, e.g. "at 4200 rpm", "Ka-band" |
+| `source` | `datasheet <file> p.N`, `vendor product page`, or `product description` |
+| `confidence` | `L0` machine-extracted · `L1` human-verified |
+

+
+## Live data and tools
+
+The snapshot here is dated; the layer grows weekly. For current data:
+
+* **Reverse search** — pass requirements, get candidates grouped A (meets all) / B (fails a
+  named requirement, both figures quoted) / C (data missing, fields named):
+  `https://newspacemarket.com/mrd-connect/match?category=reaction-wheels&momentum_min=0.2&bus_v=12`
+* **Full category dump** — `https://newspacemarket.com/mrd-connect/specs?category=star-trackers`
+* **MCP server** for AI assistants — `https://newspacemarket.com/mrd-connect/mcp`
+  (also in the official MCP registry as `io.github.newspacemarket-com/mrd`)
+* **OpenAPI 3.1** — `https://newspacemarket.com/mrd-connect/openapi.json`
+* Code, schema and examples — <https://github.com/newspacemarket-com/mrd>
+
+## How it was built
+
+Values are extracted from vendor datasheets (text, and page images for scanned documents),
+from vendor product pages and from product descriptions — the `source` column says which.
+Unit conversion is done in code, not by a model. A validation pass rejects any figure whose
+unit does not match the property, and an outlier scan flags values far from the category
+median for human review.
+
+## Limitations
+
+Coverage is not exhaustive: where a vendor publishes nothing machine-readable, the product
+is not here. Most rows are `L0` — machine-extracted and not yet checked by a person. Values
+are provided as-is; verify against the vendor datasheet before committing to a design.
