The brightest supernova in recorded history was first seen by Chinese and Egyptian observers, in the constellation Lupus near Centaurus. Although widely recorded in the rest of the world, there are no known surviving records of the event in Europe.

1938
Born, Larry Niven, science fiction author

1945
Born, Michael J. Smith, US astronaut (Challenger 10)
Michael John Smith (April 30, 1945 - January 28, 1986) was an American astronaut, pilot of the Space Shuttle Challenger when it exploded because of booster failure on the STS 51-L mission. All seven crew members died.

Smith was selected for the astronaut program in May 1980. In addition to being pilot on the Challenger, he had been slated to pilot a future shuttle mission which had been scheduled for Fall of 1986.

NASA civilian pilot Joseph A Walker flew the X-15 to an altitude of 75,190 meters (246,686 feet, 46.7 miles).

1966
The USSR launched Luna 1966A, which was tentatively identified as a Lunar orbiter mission by outside observers; the SL-6/A-2-e launcher failed to get the spacecraft to Earth orbit.

The Dutch/Itallian Beppo-SAX (Satellite for X-Ray Astronomy) was launched from Cape Canaveral, Florida.
Bebbo-SAX, launched 30 April 1996 from Cape Canaveral, Florida, was the X-Ray Astronomy Satellite selected by the Italian National Space Plan for inclusion in the Science Plan. The mission objective was to perform spectroscopic and time variability studies of celestial X-ray sources in the energy band from 1 to 200 keV, including an all-sky monitoring investigation of transients in the 2-30 keV energy range. The payload included the following narrow-field detectors coaligned to a common pointing axis: (1) four X-ray imaging concentrators sensitive from 1 to 10 keV (one of them extending down to 0.1 keV), (2) one gas scintillation proportional counter sensitive from 3 to 12 keV, and (3) a sodium iodide scintillator crystal in phoswich configuration operating from 15 to 200 keV. At 90 degrees to the axis of the narrow field instruments is an array of three identical wide field camera units sensitive from 2 to 30 keV. The SAX mission payload and science program was under the responsibility of a consortium of Italian institutes together with institutes from Holland.
