ATS-1

  • December 7, 1966

Earth from ATS-1NASA launches Aplications Technology Satellite-1, the first of a new series of experimental satellites with a goal of combining the functions of existing weather and communication satellites, with other technology demonstrations added on. ATS-1 transmits the first-ever view of the entire face of Earth visible from geosynchronous orbit, as well as testing some of the first satellite navigation technology. ATS-1’s position in orbit also proves ideal for the North-America-to-Australia link during 1967’s global Our World broadcast. ATS-1 remains in serice for almost exactly 12 years.

Janus

  • December 15, 1966

JanusFrench astronomer Audouin Dollfus discovers Janus, the tenth discovered natural satellite of the planet Saturn, orbiting just beyond the outer edge of Saturn’s ring. Confusion is caused when, mere days later, an American astronomer discovers another body in a near-identical orbit that cannot be reconciled with the orbit calculated for Janus. Only in the late 1970s will a theory emerge that explains the inconsistencies as the presence of two moons moving around Saturn as a co-orbital pair, occasionally swapping positions. Janus’ existence will be verified in 1980 by Voyager 1. (Janus is shown here in a 21st century Cassini photo.)

Epimetheus

  • December 18, 1966

EpimetheusJust days after the discovery of a satellite in a near-identical orbit, U.S. Naval Observatory astronomer Richard Walker discovers Epimetheus, another natural satellite of the planet Saturn, again orbiting just beyond the outer edge of Saturn’s ring. Many of Walker’s fellow astronomers believe this is merely a second sighting of Janus, discovered mere days before, but irregularities in the computed orbits vex astronomers well into the 1970s, at which point it is conceded that the observations are best explained by two satellites in a very close orbit to one another. Epimetheus and Janus will next be spotted by Voyager 1 in 1980, conclusively proving the existence of two bodies. Epimetheus’ name won’t be made official until 1983. (Epimetheus is shown here in a 21st century Cassini photo.)

Luna 13

  • December 21, 1966

Luna 13The Soviet Union launches unmanned space probe Luna 13 toward the moon, where it becomes the third space vehicle to successfully make a soft landing on the lunar surface. Larger than its Soviet predecessor, Luna 9, Luna 13 measures the temperature, radiation, and hardness of the moon’s surface, all useful information to have in advance of a manned landing. After operating on the lunar surface for four days, the Luna 13 lander’s batteries are exhausted and the mission is over.
