Kepler Archive is a curated astronomical data repository created to house observational data from the Kepler (spacecraft) mission and associated programs, providing calibrated time-series photometry, target catalogs, and ancillary engineering telemetry. It supports research by connecting datasets to platforms maintained by institutions such as the Space Telescope Science Institute, NASA Ames Research Center, Center for Radiophysics and Space Research, European Space Agency, and the Mikulski Archive for Space Telescopes. The archive facilitates reproducible analyses used by investigators at organizations including SETI Institute, California Institute of Technology, Massachusetts Institute of Technology, Harvard–Smithsonian Center for Astrophysics, and the Max Planck Institute for Astronomy.
The archive compiles mission data products derived from the Kepler (spacecraft) and its extended K2 (Kepler) operations, integrating pipeline outputs from the Science Processing Operations Center and calibration activities overseen by teams at the Ames Research Center and the Ball Aerospace Corporation. It links target designations with catalogs like the Kepler Input Catalog, the Two Micron All Sky Survey, the Sloan Digital Sky Survey, the Gaia astrometric catalog, and the Exoplanet Archive entries maintained by the NASA Exoplanet Science Institute. Users navigate holdings via query services modeled after the Virtual Observatory standards adopted by the International Astronomical Union and the International Virtual Observatory Alliance.
Development began in the lead-up to the Kepler (spacecraft) launch in 2009, driven by teams from the NASA Ames Research Center, the Space Telescope Science Institute, and collaborators at the SETI Institute and University of California, Berkeley. Early versions incorporated vetting procedures influenced by pipelines from the Hubble Space Telescope and archival practices at the European Southern Observatory. After the reaction wheel failures in 2013 and the repurposing to the K2 (Kepler) mission, archive workflows were extended to support target re-pointing and campaign-based products similar to those from the Transiting Exoplanet Survey Satellite and the Spitzer Space Telescope. Community advisories from the Exoplanet Exploration Program and the NASA Astrophysics Data System guided metadata standards and release policies.
Holdings include calibrated pixel files, light curve FITS files, target pixel files, cotrended data products, and high-level summaries linked to the Exoplanet Archive and the NASA/IPAC Infrared Science Archive. Files adhere to FITS conventions set by the International Astronomical Union and metadata schemas compatible with Virtual Observatory protocols used by the European Space Agency archives and the National Radio Astronomy Observatory. Catalog crossmatches reference the Kepler Input Catalog, KIC ID entries, Gaia DR2, 2MASS, WISE, and spectroscopic surveys like LAMOST and the Apache Point Observatory Galactic Evolution Experiment. Ancillary tables include target pixel masks, spacecraft attitude logs, and engineering telemetry aligned with timing standards from the Jet Propulsion Laboratory and the Deep Space Network.
Users access data via web portals hosted by the Mikulski Archive for Space Telescopes, programmatic APIs compatible with AstroPy and IRAF-style workflows, and Virtual Observatory services implemented by the International Virtual Observatory Alliance. Analysis tools integrated include light curve viewers from the NASA Exoplanet Archive, transit search algorithms derived from publications by teams at Princeton University and University of Chicago, and open-source packages maintained by the Astropy Project and the SciPy community. Community-developed applications from the Zooniverse platform and software libraries on repositories like GitHub provide pipelines for periodogram analysis, transit modeling, and pixel-level validation.
Archive-enabled research underpins major exoplanet discoveries attributed to teams at institutions such as NASA Ames Research Center, Harvard–Smithsonian Center for Astrophysics, University of California, Santa Cruz, University of California, Berkeley, and the California Institute of Technology. High-profile findings include statistical occurrence rates of small planets informed by studies linked to the Kepler dataset, validation of multi-planet systems examined alongside data from the Kepler Object of Interest catalog, and stellar asteroseismology results cross-referenced with Gaia parallaxes. The archive has supported detections later followed up by observatories including the Keck Observatory, the Gemini Observatory, the Very Large Telescope, and space missions like TESS (Transiting Exoplanet Survey Satellite) for comparative planetology.
Long-term stewardship follows practices advocated by the National Academies of Sciences, Engineering, and Medicine and archival policies implemented at the Space Telescope Science Institute and the Mikulski Archive for Space Telescopes. Preservation strategies include redundant storage across data centers at the Ames Research Center and partner facilities such as the NASA Center for Climate Simulation, data integrity checks using checksums modeled after MD5/SHA-2 practices, and metadata curation aligned with standards promoted by the International Virtual Observatory Alliance. Provenance records reference proposal IDs from the NASA Exoplanet Science Institute and team contributions from institutions including SETI Institute, Ball Aerospace Corporation, and numerous university consortia.
The archive serves as a resource for researchers at universities including Massachusetts Institute of Technology, Princeton University, University of Oxford, and University of Cambridge, for citizen scientists via Zooniverse projects, and for educators developing curricula in partnership with the Smithsonian Institution and the American Astronomical Society. Outreach initiatives reuse dataset subsets in classroom modules inspired by programs at Stanford University and Yale University and feed public datasets into visualization platforms hosted by institutions like the Chandra X-ray Observatory education office and the NASA Jet Propulsion Laboratory. Ongoing collaborations include cross-mission comparative studies with data from TESS (Transiting Exoplanet Survey Satellite), Spitzer Space Telescope, and ground-based surveys such as Pan-STARRS and the Large Synoptic Survey Telescope/Vera C. Rubin Observatory.
