Dr. John F. Clark, Goddard Space Flight Center Director, and Dr. James W. Smith, president of Greenbelt Homes, Inc., signed a cooperative agreement to install experimental solar heating units in four four-family housing units in Greenbelt, Md. During the first phase of the project, all four of the units would be instrumented to measure heat loss and fuel-consumption characteristics, and two of the four would be fully insulated. Based on the cost-effectiveness of the first phase, the two insulated buildings would be equipped with solar heating units designed to augment existing hot-water radiator systems. The remaining two units would serve as control for comparison. The solar units, which would be designed at GSFC, would be installed in time for the 1975-1976 heating season.

The first airborne terminal for an Air Force communications satellite system was being installed in a C-141 aircraft as part of a flight-test program to develop a system for transmitting high-priority messages throughout the world via Air Force repeater satellites. In addition to the C-141 terminal, the system included six additional airborne and four ground terminals. Results of the 6-mo test would help DOD decide whether the terminals should be produced in quantity. (AFSC Release OIP 303.74)
