Esox SpaceTier A — Prospecting Dossier
Single-body report: reflectance spectrum, phase curve parameters, delta-v estimate, diameter, albedo, taxonomy, and meteorite analog — where available from the GASP/GAPC catalog suite.
Space Data Intelligence
Validated data for the space economy
Esox Space builds on two open Gaia catalogs — GASP (19,190 asteroid reflectance spectra, published RNAAS) and GAPC (128,885 phase curve parameters) — and a merged catalog of 18,307 complete asteroid profiles (DOI: 10.5281/zenodo.19867798) — delivering validated, cross-matched data for mission screening and due diligence.

Gaia DR4
Full pipeline update planned on next Gaia data release — expected to significantly expand catalog size.
Catalog Suite
Two open catalogs built on the same reproducible infrastructure — GASP for reflectance spectra, GAPC for phase curve parameters. Both published on Zenodo under MIT license.
GASP — Reflectance Spectra
19,190 asteroids · 77 columns · NUV-corrected · Published RNAAS 2026
GAPC — Phase Curves
128,885 asteroids · HG1G2 parameters · diameter, albedo, taxonomy · Zenodo 2026
Gaia DR3 acquisition
Reflectance spectra from ESA’s archive, structured for reproducible processing.
NUV correction
Published correction for near-ultraviolet systematics (Tinaut-Ruano et al.).
Cross-match & enrichment
Photometry, families, albedo where available — aligned to the public GASP catalog.
ML classification & ranking
Random Forest classifier trained on 358 labelled objects. F1-macro 0.72, extending taxonomy to 42.7% catalog coverage.
Services — In Preparation
Services
Fixed-scope products where possible. All commercial outputs label screening estimates as illustrative; independent verification remains your responsibility.
Current catalogs are based on Gaia DR3. Full commercial services launch with Gaia DR4 (expected late 2026), which will significantly expand coverage and data quality. Early enquiries welcome at vienna@esoxconsult.com
Tier B — Target Filter
Portfolio-level shortlist against constraints you define. Delivered as tables and a concise technical memo. Illustrative economic figures where shown.
Tier C — Mission Analysis
Deeper trajectory-accessibility and scenario work for a narrow target set — scoped after intro call. Scoping calls welcome now — contact vienna@esoxconsult.com
All economic figures are illustrative. No investment advice implied.
Use Cases
Who uses Esox Space data
Mission target selection
Identify accessible, high-value asteroid candidates before committing mission resources. GAPC provides delta-v proxies and compositional screening for 128,885 objects — filtered to your orbital and mineralogical constraints.
