Checkout operations for Skylab 4, scheduled for Nov. 11 launch to crew the Skylab 1 Orbital Workshop launched May 14, went into a hold period at Kennedy Space Center. Operations had been accelerated so that Skylab 4 could act as a rescue vehicle if needed for Skylab 3, docked with the Workshop since July 28. The acceleration made necessary a hold until Sept. 25 so checkout operations could resume their normal flow [see July 28-Sept. 25]. (KSC Release 207-73)
September 11-12: The third colloquium of users of NASA'S Structural Analysis (NASTRAN) computer system was held at Langley Research Center. Some 300 industry and Government representatives heard 40 papers and talks on the uses of NASTRAN to integrate project disciplines, to manage design work data and make it available during any stage of a design cycle, and as a source of computer analyses of structural stress, buckling, vibration, and transient-response of large and complex structures.

September 11, 13, 18: The House Committee on Science and Astronautics' Subcommittee on Energy held hearings on geothermal energy. Dr. Alfred J. Eggers, Jr., Assistant Director for Research Applications with the National Science Foundation, testified Sept. 11 that geothermal energy was recognized as a "currently viable and relatively unpolluting energy resource." Its importance depended upon development of new technologies and "resolution of institutional constraints.' NSF was recommending a program to develop necessary technologies and "to synthesize these into pilot plants capable of generating power from a variety of geothermal sources." An advantage of geothermal energy was "that construction of power plants can be carried out in a relatively short time." With solution of the technical problems in extracting the earth's heat and converting it into electricity, "the commercial impact of geothermal energy could begin to be felt within this decade. Geothermal energy is, therefore, counted on to contribute at least regionally to a resolution of the energy crisis in the short term as well as to provide sizable blocks of energy in the remaining years of this century."
