[edit] Astronomy and space exploration
- February 13 - Asteroid 7253 Nara is discovered by Fumiaki Uto.
- December 2 - STS-61 is launched. This Space Shuttle mission to the Hubble Space Telescope (HST) installs corrective optics, plus upgrades, that not only allow the telescope to focus properly, but also increase magnification/clarity beyond the original design. HST had been pre-designed for such continuous improvement.
- The first definite asteroid moon is confirmed when the Galileo probe discovers Dactyl orbiting 243 Ida.[1]
[edit] Computer science
- March 22 - The Intel Corporation ships the first Pentium chips
- March 31 - A bug in a program written by Richard Depew sends an article to 200 newsgroups simultaneously. The term spamming is coined by Joel Furr to describe the incident.
- April 22 - Release of version 1.0 of the Mosaic web browser.
