IBM introduces the Model 3340 hard disk drive system for its System/370 mainframe computers. Housed in a large casing similar to a combined washer and dryer, this is the birth of modern hard disk technology, with read and write heads integral to the drive itself rather than being mounted on an arm which reaches into the drive casing. The 3340’s removable modules, each containing drive platters and the read/write heads, can be swapped out with other modules containing other drives. IBM ships the 3340 with two maximum storage capacities: 35 megabytes or 70 megabytes; the unit is internally called a Winchester hard drive, a case of a code name that sticks well beyond development. The 3340 is available through 1984.

CBS premieres the made-for-TV movie Genesis II, starring Alex Cord, Mariette Hartley, Ted Cassidy, and Percy Rodrigues. Created and written by Star Trek creator Gene Roddenberry, Genesis II is clearly a series pilot, the first of several attempts by Roddenberry to chart a career beyond Star Trek. The story concerns an astronaut named Dylan Hunt who is frozen in suspended animation, only reawakening after the fall of human civilization; the pilot does not result in a series pickup, though the story of Dylan Hunt will form the basis of Gene Roddenberry’s Andromeda, a syndicated series produced in the early 2000s after Roddenberry’s death.

The Soviet Union launches a second space station, and the first station designed exclusively for military tasks in orbit. Salyut 2 is the first station to use the Almaz military space station design devised in the 1960s as a response to the US Air Force’s never-flown Manned Orbiting Laboratory. Within two weeks, however, technical difficulties take their toll: Salyut 2 begins to tumble out of control, and its crew compartment depressurizes. (The redesigned Soyuz vehicle is not ready to fly yet, so no crew ever visits Salyut 2.) The second Soviet space station burns up in the atmosphere less than two months after launch.
The unmanned space probe Pioneer 11 is launched on a course that will be one of the first real tests of the theory of gravity assist. Reaching Jupiter in 1975, it will use the giant planet’s gravity to throw it across the solar system to rendezvous with Saturn, the first human-made vehicle to visit that planet. The experience gained with Pioneer 11’s groundbreaking trajectory through the solar system will prove instrumental in the upcoming Mariner Jupter/Saturn ’77 mission, which is later be renamed Voyager.
