ASSOCIATION MEMBERSHIP

NASA’s National Space Science Center is seeking capability statements for association membership that will support the provision of high‑accuracy ephemeris data and conjunction‑assessment services for NASA assets. The effort will be performed under a sole‑source contract to Space Data Association Ltd, with work centered on maintaining a secure repository, converting and screening ephemerides, providing twice‑daily notification of close approaches, and delivering web‑based analysis and maneuver‑planning tools. The contract period runs from July 1 2026 through June 30 2027, and responses are due by mid‑October 2026. • Provide a secure, redundant central repository for operator‑provided ephemeris predictions. • Perform twice‑daily screening of NASA asset ephemerides against other operators’ data and issue notifications. • Supply web‑based tools for close‑approach analysis, contact sharing, and avoidance‑maneuver planning.
