* 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.
