Downlink · the open-data ground station

Every archive, one antenna

The world's observation satellites publish their science to public archives. DOWNLINK pulls that data down, shows what each mission offers, and hands it to the analysis pipeline — TESS transits, JWST spectra, Hubble imaging, and more, all from NASA's MAST and partner archives.

Variable-star workflow (fold → classify → verify)

Classify a variable's light-curve shape, then confirm it against space (Gaia) and ground-based (AAVSO VSX) records. The pipeline is systematic and every verdict is checkable.

The archives

TESS

extended

NASA · MAST

All-sky transit survey — full-frame images and 2-minute light curves for millions of stars. The frontier THE FIELD flies over.

exoplanetstime-domain

James Webb (JWST)

operational

NASA · ESA · CSA · MAST

The infrared flagship at Sun–Earth L2. Public imaging and spectra after the proprietary period — atmospheres, first galaxies, protoplanetary disks.

Hubble (HST)

operational

NASA · ESA · MAST

Three decades of optical/UV imaging and spectroscopy — the most-cited archive in astronomy.

NASA · MAST

The survey that found thousands of planets. Long-baseline photometry still yielding discoveries in the archive.

Gaia

completed

ESA · ESA Gaia Archive

Positions, distances, and motions for ~2 billion stars — the 3D map the whole field builds on.

NASA · Chandra Data Archive

High-resolution X-ray imaging — black holes, supernova remnants, hot gas in clusters.

Rapid-response gamma-ray-burst and transient follow-up — the sky's fast-alert workhorse.

How CAPCOM gets smarter

Every analysis the community downlinks and validates through a Go/No-Go review becomes an admitted source CAPCOM may cite — a governed, auditable knowledge base that grows with use (Constitution §IV.7). CAPCOM improves not by an opaque model swap but by accumulating vetted, sourced results: the more real data flows through DOWNLINK and passes review, the more it can ground its answers.

Live coverage is served by the discovery service (NASA MAST via astroquery). Archive links go to each mission's public data host. This is DOWNLINK v1 — per-mission product download + more archives (Gaia TAP, Chandra) are the declared next reach.
