NASA Facts: Lot of 14 Informational Sheets

Fourteen issues of “NASA Facts,” the agency’s ongoing series of single-topic public-information sheets, spanning center profiles, mission summaries, and classroom science handouts. “Apollo 17: The Last Apollo” and “Manned Space Flight — The First Decade” both look back on the program from its close. “Most-Asked Questions About Space” answers the mail NASA’s Public Affairs Office says it received at a rate of 7,500 letters a month, addressing everything from program cost (“about 2-1/2 percent of all federal spending”) to whether NASA will ever fly a woman astronaut (“probably, but not in the immediate future”). Four sheets belong to the “Science Series” issued for junior and senior high classrooms in August 1967: Telemetry, Weightlessness, Spacecraft Tracking and Communication, and Rocket Propulsion. “The Pioneer Spacecraft” (NF-31, Vol. IV, No. 3) covers NASA’s sun-orbiting Pioneer probes monitoring interplanetary space and forecasting solar flares, referencing Pioneer VI (launched December 1965) and Pioneer VII (August 1966), placing this issue around 1966–67. Also included: profiles of the Lyndon B. Johnson Space Center and the Langley Research Center (the latter’s own headline misprints “Research” as “Reseach”), a Gemini Program Summary, “Project Apollo: Manned Exploration of the Moon,” “Space Benefits,” and “Explorer XXIX (The Geodetic Explorer)” on the geodetic satellite that mapped irregularities in Earth’s gravity field.
