This record unit documents the operation of Project Celescope from its inception in 1958 until shortly before the launch of the experiment in December 1968. Records
include correspondence; memoranda; TWX messages; contracts, invitations, bids and proposals; reports; and related materials concerning the technical development of Celescope;
involvement of NASA in the project; SAO administration of the project; and the selection and work of contractors producing instruments for the project.
Conceived in 1958, Project Celescope was an experiment undertaken by the Smithsonian Astrophysical Observatory (SAO) to study the atmospheres of the hotter stars by
means of photometric measurements in those regions of the ultraviolet that are accessible only from above the earth's atmosphere. Measurements were achieved by mounting telescopes,
in an orbiting satellite, that would focus starlight on ultraviolet-sensitive television cameras. Project Celescope was funded by the National Aeronautics and Space Administration
(NASA) as part of its Orbiting Astronomical Observatory (OAO) program. The project reached a climax on December 7, 1968, when NASA launched the second OAO satellite containing
the Celescope experiment. More than 8,500 photographs of more than 2,800 areas of the sky were made during the experiment's lifetime.
From 1958 to 1965, Project Celescope existed as a separate division of SAO. In 1965 the project was placed under administrative control of the newly created Department
of Flight Operations. The project's primary staff included Fred Lawrence Whipple, project director; Robert J. Davis, project scientist; and Francis R. Nitchie, Jr., engineering
administrator, 1958-1962. In 1962, the title of the latter position was changed to project manager. Project managers included G. K. Megerian, 1962; Charles A. Lundquist, acting
project manager, 1963; and John J. Burke, 1964-1968.
