Satellites and Launches
TLE history, SATCAT, Starlink fleet, constellations, ground stations, launch logs, reentry events, and satellite databases.
Galaxies and Cosmology
Galaxy morphology, clusters, properties, redshift surveys, quasars/AGN, gravitational lenses, and Type Ia supernovae for cosmology.
Stellar Catalogs
Spectroscopic surveys (RAVE, APOGEE, GALAH), nearby stars (Hipparcos, CNS5), and stellar populations (Wolf-Rayet, carbon, brown dwarfs, white dwarfs).
Space Probe & Mission Datasets
Voyager, Pioneer, Cassini, Mars Express, Rosetta, Curiosity, Perseverance, InSight. 50+ years of interplanetary spacecraft data in Parquet.
Planetary Science Datasets
Impact craters (Moon, Mars, Ceres), IAU planetary nomenclature, and meteorite landings. The most comprehensive surface geology datasets.
Space Weather Datasets
Solar flares, CMEs, geomagnetic storms, Kp/Ap/Dst/AE indices, F10.7, sunspot numbers, solar wind, and NOAA alerts. Updated daily.
Asteroids and Small Bodies
JPL SBDB, NEO close approaches, Sentry impact risk, asteroid taxonomy, families, lightcurves, mining, comets, and meteoroids.
Sky Surveys
Multi-wavelength sky survey catalogs: radio (NVSS, FIRST, VLASS), X-ray (eROSITA, Chandra), gamma-ray (Fermi), and reference frames.
Variable Stars and Transients
Cepheids, RR Lyrae, eclipsing binaries, variable star catalogs (GCVS, AAVSO VSX), supernovae, TDEs, and exoplanet transit timing.
Solar System Datasets
Planetary missions, crater databases (Moon/Mars/Ceres), atmospheric profiles (Jupiter/Titan), marsquakes, and Mars surface exploration.
Physics Datasets
PDG particle properties, cosmic ray spectra, ultra-high-energy events, and gamma-ray catalogs from Fermi, Swift, INTEGRAL, HAWC, and LHAASO.
Astronomy Datasets
Exoplanets, gravitational waves, pulsars, GRBs, FRBs, quasars, variable stars, and million-source radio/X-ray sky surveys in Parquet.
Orbital Mechanics Datasets
Satellites, TLEs, launches, NEOs, and asteroids. Track every orbiting object from NORAD SATCAT to Starlink fleet health and JPL impact risk.
