NASA-UAP-D5 is a three-page PDF released in Department of War PURSUE Release 01 on May 8, 2026. The release metadata describes it as an excerpt from the Apollo 17 Crew Debriefing for Science, dated January 8, 1973, in which Dick Henry, a co-investigator on the Apollo 17 ultraviolet experiment, discussed unexpected results.1
Apollo 17 Science Debrief
Apollo 17 was the ninth crewed U.S. mission to the Moon and the sixth to land astronauts on the lunar surface.1 The PDF cover identifies the underlying source as MSC-07632, Apollo 17 Crew Debriefing for Science, prepared by the Planetary and Earth Sciences Division at the Manned Spacecraft Center in Houston.2
The released file is not the full debriefing. It contains the cover and transcript pages 119-120, where Henry is already speaking when the excerpt begins and is still speaking when it ends.2
Henry's Ultraviolet Findings
The excerpt opens with Henry finishing a discussion of whether ionized hydrogen could explain what was gravitationally holding the Coma cluster together. He says the Apollo 17 ultraviolet work looked for redshifted Lyman-alpha radiation from that hydrogen and did not see it, leaving the cluster question unresolved in this passage.2
The UAP-relevant language appears in Henry's fourth point, where he turns from known ultraviolet light in the Milky Way to observations looking toward the North and South Galactic Poles. He compares the question to the unexpected discovery of an X-ray background and says that, in ultraviolet astronomy, "you never know until you look."2
Henry says the Apollo 17 data showed a spectrum above the instrument's dark count, and that the spectrum resembled a hot star even though there were "no hot stars" in the field of view.2 His conservative interpretation was ultraviolet light from hot stars in the galactic plane reflecting off interstellar dust, but he also said some spectral characteristics did not fit that theory and that the signal could be "extragalactic radiation."2
The next section discusses Lyman-alpha hydrogen radiation as a separate problem. Henry describes hydrogen inside the solar system reflecting sunlight, likely from interstellar hydrogen streaming through the solar system, and says Apollo 17 collected a large data set for later analysis.2
No Lunar Object Report
The released pages do not describe a discrete object, spacecraft, maneuver, close-range visual sighting, or astronaut report of an object near the Moon. They preserve a scientist's discussion of ultraviolet spectra, background radiation, and possible astrophysical explanations.
The excerpt also has hard boundaries. It begins mid-discussion, ends mid-topic, and omits the surrounding debriefing pages. Its UAP relevance comes from the Department of War's release framing and from the record's unexpected-observation language, not from a conclusive identification of an anomalous vehicle or event.12
A Narrow Apollo Data Point
NASA-UAP-D5 matters because it gives primary-source context for a historical Apollo record included in a modern UAP release. The public text shows a real unresolved scientific observation in Apollo 17 ultraviolet data, but the uncertainty is about source interpretation in astronomy rather than about an observed craft.
That distinction is useful. The record supports careful claims about unexpected spectra, interstellar dust, possible extragalactic radiation, and the need for detailed computer analysis. It does not support stronger claims about object identity, origin, or performance without evidence outside this released excerpt.2
