NASA-UAP-D034, Space Shuttle Anomaly Evaluation Working Group Technical Summary, 1998

NASA-UAP-D034 is a technical memorandum from the National Aeronautics and Space Administration, dated October 15, 1998, and attributed to Johnson Space Center, Texas. The Department of War declassified and released it as part of PURSUE Release 05 on August 7, 2026, under Section 1842 of the National Defense Authorization Act for Fiscal Year 2024. ¹²³

  Provenance and Content

The memorandum was produced by NASA's Space Shuttle Anomaly Evaluation Working Group. It reviews optical tracking data and ice-debris particle dynamics from shuttle missions, including STS-80, and covers sensor captures from those flights that the working group could not resolve. The version released under PURSUE Release 05 retains the observable data while withholding whatever material remains restricted.¹²³

  What the Record Supports

The document shows NASA's own working group evaluating shuttle-flight sensor anomalies against known ice-debris behavior, not a claim of anomalous origin. Some of the captures reviewed remained unresolved at the time the summary was written.³
