    NASA Explorer 6: Archive of Original Material from the 1959 Launch of this Important Research Satellite, also Photos and Press Release on the Pioneer P-3 Lunar Orbiter. An extensive collection of period photos, bulletins, and press releases regarding this satellite launched August 7, 1959, from Cape Canaveral, to study radiation, cosmic rays, geomagnetism, and upper atmosphere radio propagation. Included in this archive are the following.
    Photos: Four original U.S. Air Force 8" x 10" B&W glossy photos with captions on verso- three showing the satellite in assembly stages and one of the launch atop a Thor-Able rocket.
    Press Releases: A collection of sixteen printed press releases, many multi-page, from the satellite's primary builder, Space Technology Laboratories, and many of the sub-contractors and contributors. STL's releases titled Components, Environmental Testing, Multiplexer, Radiation Experiments, Satellite Comparison, and Key Personnel are included. Also, releases from Gillfillan Brothers, Gulton Industries, Hallamore Electronics, Hoffman Electronics, Motorola (2), Radiation, Inc., Radio Propagation Laboratory (Sanford University), Rantec, Space Electronics, and University of Chicago.
    Official Explorer Bulletins: Eight different (nine total) multi-page weekly bulletins giving the details of the satellite's performance and a summary of data received by day and station. The very last bulletin in the series, dated 8 October through 14 October, begins as follows: "Continued efforts are being made to acquire the Explorer VI satellite. No data has been transmitted since the evening of the 6th of October." As it turned out, the satellite would never be heard from again. Its orbit decayed July 1, 1961.
    Biographies and Photos: Three single page bios and 4" x 5" photos of the key STL personnel: Ruben F. Mettler, Executive V.P.; George E. Mueller, Vice president and Associate Director R&D; and Adolph K. Thiel, Program Director, Experimental Space Projects.
    Additional Explorer 6: A teletype page directed to STL, photostatic copies of technical information and a map of the satellite's trajectory, and a 24-page paper by Frank A. Burnham on the Explorer Program.
    NASA Pioneer P-3: Four 8" x 10" B&W glossy Air Force photos of the craft pre-launch and an extensive NASA press release regarding this mission, also called Atlas-Able 4, that was launched on November 26, 1959, and failed 45 seconds into the flight. Its primary objective was to explore space between the earth and the moon with a highly-instrumented 372-pound payload.
    Additional research material downloaded from the Internet also included in this binder/portfolio. Generally very fine.
