NASA and the United States Weather Bureau launch the seventh experimental TIROS weather satellite, TIROS-7. In addition to observing weather on Earth, TIROS-7 carries instruments to measure electron activity in Earth’s vicinity and to measure the temperature of space. Enhancements designed to extend the satellite’s life prove to be wildly successful: TIROS-7 is the longest-lived of the experimental TIROS series, remaining in service for five years (and, critically, five hurricane seasons).
