Goddard Space Flight Center awarded Boeing Co. a fixed price incentive contract for $8 236 000 to provide modules for the first two Atmospheric Explorer missions: AEM-A (heat capacity satellite) and AEM-B (the stratospheric aerosol gas experiment-SAGE). AEM-A, scheduled for launch in 1978, would carry a heat-capacity mapping radiometer that NASA would acquire independently, to gather thermal-inertia data on rock types, location of mineral resources, soil moisture, and vegetation-cover temperature measurements. AEM-B's SAGE would measure spatial distribution of stratospheric aerosol and ozone on a global basis. It had been scheduled for launch in 1979. (NASA Release 75-299; WSJ, 24 Nov 75, 28)
