Died, Edwin Hubble, American astronomer

Edwin Powell Hubble (20 November 1889 - 28 September 1953) was a noted American astronomer, generally credited for discovering and proving redshift and that the universe is expanding. (The redshift had actually been observed by Vesto Slipher in the 1910s, but the world was largely unaware.)

Hubble's studies at the University of Chicago concentrated on mathematics and astronomy. After earning a law degree at Oxford, and teaching high school in New Albany, Indiana, he returned to astronomy at the Yerkes Observatory of the University of Chicago, where he earned a Ph.D. in 1917. In 1919 Hubble was offered a staff position by George Ellery Hale, the founder and director of Carnegie Institution's Mount Wilson Observatory, near Pasadena, California, where he remained until his death. Shortly before his death, Palomar's 200-inch Hale Telescope was completed, Hubble was the first to use it.

His arrival at Mount Wilson coincided roughly with the completion of the 100-inch Hooker Telescope, then the world's most powerful telescope. Hubble's observations in 1923-1924 with the Hooker Telescope established beyond doubt that the fuzzy "nebulae" seen earlier with less powerful telescopes were not part of our galaxy, as had been thought, but were galaxies themselves, outside the Milky Way. He announced his discoveries on 30 December 1924.

Subsequently, with Milton Humason, Hubble discovered the velocity-distance relation, now know as the Hubble's law, which led to the concept of the expanding universe.

NASA's orbiting Hubble Space Telescope is named in his honor.

The US Navy launched the (classified) Transit 5B-1 navigation satellite and the APL SN 39 research satellite from Vandenburg, California on a Thor Able-Star booster.

The mission of Satellite 1963-038C (APL SN 39), launched together with a classified Department of Defense spacecraft on 28 September 1963, was to measure the omnidirectional flux of protons and electrons at various energy levels, radiation effects on transistors, and the effectiveness of thermal coatings. Its planned orbit was 1120 x 1070 kilometers with an inclination 88.9 degrees. The satellite weighed 62 kg; its body was in the shape of an 0.46 meter x 0.25 meter octagonal prism. It was powered by four solar blades, and transmited on 136, 162, and 324 MHz. The spacecraft was built for the Bureau of Naval Weapons. In 1967, it was still sending usable data from all systems.

1971 04:00:00 GMT
Japan launched SS-01 Shinsei into orbit from Kagoshima for scientific observations in outer space, the first Japanese scientific satellite.

Shinsei (new star) was the first Japanese scientific satellite, launched 28 September 1971. The scientific payload included solar radio receivers, cosmic-ray detectors, and ionospheric probes. The power supply system consisted of solar cells and nickel cadmium batteries. The satellite was a 26-sided body measuring 71.2 cm in diameter across the flat sides. All experiments operated nominally after launch, except for the electron temperature probe (damaged on separation) and one Geiger tube (failed after 3 days). Otherwise, good data were received for four months until a tape recorder failure occurred. Only a very limited amount of realtime data was subsequently obtained. By late 1973, the experimental equipment had become no longer useful for meaningful scientific observations.

USSR launched Luna 19 to the Moon, a heavy Lunar orbiter which conducted Lunar surface mapping.

Luna 19 was placed in an intermediate Earth parking orbit on 28 September 1971, from which it was put on a translunar trajectory by the Proton Block D stage. It entered Lunar orbit 3 October 1971. Luna 19 extended the systematic study of Lunar gravitational fields and location of mascons (mass concentrations). It also studied the Lunar radiation environment, the gamma-active Lunar surface, and the solar wind. Photographic coverage via a television system was also obtained.

USSR launched the Intercosmos 24 scientific satellite from Plesetsk, which released the Czech Magion 2 subsatellite, permitting simultaneous spatially separated investigations of plasma processes in circumterrestrial space.

The Intercosmos 24 scientific satellite, launched 28 September 1989, carried particles and fields experiments for a comprehensive study of the processes of propagation of low-frequency electromagnetic waves in the Earth's magnetosphere and their interaction with charged particles of the radiation belts, in cooperation with Bulgaria, Czechoslovakia, the German Democratic Republic, Hungary, Poland and Romania (the international scientific project entitled "Aktivny"), including US participation. The Czechoslovak Magion 2 subsatellite was deployed on 3 October 1989, which examined signal propogation from Intercosmos 24 for research of the magnetosphere and the ionosphere of the Earth. Magion 2 formed a part of the scientific program of Intercosmos 24: execution of the Aktivny project in conjunction with Intercosmos 24 permitted simultaneous spatially separate investigations of plasma processes in circumterrestrial space.
