Operation Hurricane, the first test detonation of a British-built atomic bomb, takes place aboard a Royal Navy frigate anchored near the Monte Bello Islands off of the western Australian coast. The detonation has a yield of 25 kilotons, and is remotely detonated aboard the frigate to gauge the damage that would result from a scenario in which a nuclear device is smuggled into a sea port aboard a ship. This is a continuation of Britain’s own nuclear weapon development program initiated during World War II, and makes the U.K. the third nuclear-armed nation on Earth.

The recently-rechristened Environmental Sciences Service Administration (previously the U.S. Weather Bureau) launches, with the help of NASA, weather satellite ESSA-3, the third in a constellation of Earth-observing weather satellites. The timing of the launch is fortunate, as ESSA-3 takes up its station in orbit mere days before the unexpected shutdown of ESSA-1’s camera system. ESSA-3’s own camera system begins to fail in less than a year, and it is deactivated near the end of 1968 due to continued system failures.

Long after Glen A. Larson’s science fiction series Battlestar Galactica has completed its run, a California judge throws out 20th Century Fox’s 1978 lawsuit, which alleged that Galactica was too close to elements of Star Wars for the studio’s comfort. (Also at issue, though not specifically mentioned in the legal proceedings, was Universal Studios’ hiring of such Star Wars personnel as FX guru John Dykstra and illustrator Ralph McQuarrie to work on Galactica.) Universal’s television series is declared different enough in key areas to not be considered a rip-off – small comfort for the studio, since ABC cancelled had the series earlier in the year. Still, Galactica’s legal status will come into play later, as Universal will later reassert and exploit its rights to the basic Battlestar Galactica storyline in the 21st century. This is not the end of the lawsuit, however; much like both franchises, it too is revived in 1983, and Universal is ordered to pay 20th Century Fox a settlement of nearly a quarter million dollars in 1984.

This new module is a permanent addition to the final Salyut station, offering more habitable space for work and storage aboard the aging station. Kosmos 1686 arrives with nearly 10,000 pounds of supplies and consumables, and serves as a case study to help engineers plan the upcoming Mir space station, which is designed from the outset to consist of several add-on modules.
