Janus Audouin Dollfus is credited with the discovery of Janus in 1966 but it is not certain whether the object he saw was Janus or Epimetheus and his observations led to a spurious orbit. www.daviddarling.info /encyclopedia/J/Janus.html   (294 words)

Lake County Astronomical Society NightTimes Audouin Charles Dollfus, a French physicist and astronomer was born on November 12, 1924. In 1966 Dollfus discovered Janus, the innermost moon of Saturn, at a time when the rings to which it is very close were seen edge on from Earth (and practically invisible). Dollfus estimated that the atmospheric pressure at ground level was about 1 mm of mercury. www.bpccs.com /lcas/Articles/dollfus.htm   (494 words)

AllRefer.com - Janus, in astronomy (Astronomy, General) - Encyclopedia The French astronomer Audouin Dollfus is credited with the discovery of Janus in 1966. Janus and Epimetheus are co-orbital, that is, they share the same average orbit; about every fourth year : at closest approach : the lower, faster satellite overtakes the other, they exchange angular momentum, and the lower one is boosted into a higher orbit while the higher one drops to the lower orbit. Also known as Saturn X (or S10), Janus is an irregularly shaped (nonspherical) body measuring about 122 mi (196 km) by 119 mi (192 km) by 93 mi (150 km); it orbits Saturn at a mean distance of 94,120 mi (151,472 km), and has equal orbital and rotational periods of 0.6945 earth days. reference.allrefer.com /encyclopedia/J/Janus-ast.html   (297 words)

Dollfus_harris.doc Dollfus was one of the first, probably the first, person in France to obtain lunar samples for analysis. Dollfus' father was a famous balloonist in France, which explains his interest (and expertise) in ballooning. So while the field has advanced to the point that Dollfus' contributions are easily criticized and could be dismissed as currently irrelevant, I think he deserves to be remembered as a pioneer. dorothy.as.arizona.edu /sykes/DPS/Dollfus_harris.doc   (568 words)

Dollfus, Audouin Charles In 1966 Dollfus discovered Janus, the innermost moon of Saturn, at a time when the rings - to which it is very close - were seen from Earth edgeways on and practically invisible. Hoping to establish the mineral composition of the Martian deserts, Dollfus checked the polarization of light by several hundreds of different terrestrial minerals to try to find one for which the light matched that polarized by the bright Martian desert areas. He was the first to detect a faint atmosphere round the planet Mercury, in 1950, and established that the Moon does not have one. www.cartage.org.lb /en/themes/Biographies/MainBiographies/D/Dollfus/1.html   (151 words)

Janus (moon) - Wikipedia, the free encyclopedia The discovery of Janus is attributed to its first observer: Audouin Dollfus, on December 15 1966 (IAUC 1987 (http://cfa-www.harvard.edu/iauc/01900/01987.html#Item1)). Astronomers assumed that there was only one body in that orbit, and accordingly had a hard time figuring out their orbital characteristics; it is obviously impossible to reconcile the observations of two distinct objects as a single object. The new object was given the temporary designation S/1966 S 2. peekskill.us /project/wikipedia/index.php/Janus_(moon)   (449 words)

Dollfus, Audouin Charles (1924-) Before the Viking landings, he correctly concluded, from polarization experiments with hundreds of different terrestrial minerals and polarization observations of the Red Planet, that the Martian deserts are strewn with iron oxide (Fe Since 1946, he has been at the Meudon Observatory outside Paris. Before the first planetary probes, Dollfus sought evidence for tenuous atmospheres around Mercury and the Moon, and made the first ascent in a stratospheric balloon in France in order to carry out detailed studies of Mars.

Strange Lights Seen on the Moon French astronomer, Audouin Dollfus of Observatoire de Paris, has recently finished analyzing his 1992 observation of disturbances on the lunar surface. Dollfus believes that the glows are caused by escaping gas that lifts dust off the lunar surface, into the sunlight. On December 30, 1992, Dollfus witnessed something on the moon that was not there the day before. www.21stcenturyradio.com /lightsonmoon-12.10.00.htm   (280 words)

History and Technical Notes In 1959, Audouin Dollfus carried scientific instruments to 40,000 feet using a chain of 105 balloons that stood 1,500 feet tall. Don Piccard, son of Jean and a major figure in the development of the modern sport of hot-air ballooning, made flights using clusters of plastic balloons in 1957 and 1962, including a flight to 17,747 feet that still stands as a world altitude record for category AA-2 balloons.
