The U.S. Air Force launches NAVSTAR-1, the first of a planned constellation of experimental satellites supporting the Department of Defense’s Global Positioning System project. Envisioned as a network of satellites providing extremely accurate location data for military purposes, the Global Positioning System will later grow to service civilian customers as well. Three other NAVSTAR satellites are launched in 1978 alone, and later satellites in the original NAVSTAR series will be launched betwen 1980 and 1985. Unlike the later, more advanced NAVSTAR II satellites of the 1990s, data from the original NAVSTAR constellation is restricted to the American military.

Corvus Systems introduces its Winchester hard disk drive for the Apple II computer, available with five or ten megabytes of storage. A bulky device requiring its own power supply independent of the computer to which it’s connected, the Winchester drive carries a $5,000 price tag and an unconventional data backup system, Corvus Mirror, which uses videocassettes (also a fairly new technology). As the investment in this new mass storage technology is fairly daunting, Corvus will introduce a networking system the following year to allow multiple computers access to a single hard drive.

Space Shuttle Columbia is launched on the 75th shuttle flight, staying in orbit for nearly 16 days. The crew attempts to deploy a tethered satellite experiment flown unsuccessfully in 1992, only to watch as the tether snaps with the satellite 12 miles away from the shuttle. The remainder of the flight is spent conducting planned material science experiments. Aboard Columbia for her 19th flight are Commander Andrew Allen, Pilot Scott Horowitz, Payload Commander Franklin Chang-Diaz, and mission specialists Maurizio Cheli, Jeffrey Hoffman, Claude Nicollier and Umberto Guidoni. To this day, video of the satellite floating in space after the tether failure is circulated as “proof” of the existence of UFOs.
