Syncom 3

  • August 19, 1964

Syncom 3NASA launches the experimental, Hughes Aircraft-built communications satellite Syncom 3 into a geostationary orbit, the first human-made satellite to occupy that orbit. Much like Syncom 2, Syncom 3 is capable of handling two-way telephone calls, as well as teletype and fax transmissions. Placed in an orbit roughly over the International Date Line, Syncom 3 is instrumental in providing live TV coverage of the 1964 Summer Olympics from Tokyo to American television audiences, and the satellite’s technology is considerably upgraded compared to that of Syncom 2 in order to handle television transmission. Control of Syncom 2 is handed over to the Department of Defense in 1965 once NASA has completed its run of experimental communications tests.

Nimbus-1

  • August 28, 1964

NimbusNASA and the United States Weather Bureau launch the first test article of the next-generation weather satellite, Nimbus-1. Using the more advanced camera technology (including infrared filters to watch cloud motion even on Earth’s night side) tested aboard TIROS-8, Nimbus-1 provides a vast improvement on satellite weather observations over the hardware on the TIROS experimental satellites. The first Nimbus satellite remains in service for only a month; later Nimbus satellites continue to be launched into service well into the late 1970s, and most of them remain operational into the 1980s.
