... Artist?s conception of the collision of Comet Shoemaker-Levy 9 with Jupiter, as seen from the Galileo spacecraft. At the time of the first impact, the comet fragments will be much farther apart than shown in this illustration. ... One orbit, computer May 18, 1993 by Syuichi Nakano, showed that the comet passed close to Jupiter in July 1992, and would pass within 45,000 kilometers of the center of Jupiter in July, 1994. ... The fragments of Shoemaker-Levy 9 move around Jupiter. ...

Originally Discovery had been set to launch on 1 November, but this was delayed when fatigue cracks were found in the structure of its External Tank. ... A little bit of trivia is that Discovery has actually made the only shuttle-era Christmas time flight to date, this was STS-103 ,€а a mission to repair the Hubble Space Telescope in 1999. ...

... Shortly after its discovery it was determined to be in a highly elliptical path near Jupiter and on a collision course. ... The size and mass of the original body and the individual fragments is as of this writing still highly uncertain. ... Between 16 July 1994 and 22 July 1994 the fragments impacted the upper atmosphere of Jupiter. ... The pictures were posted to the Net within hours of the impacts and caused severe overloading on some ftp and WWW sites. ... JPL's SL9 page . ... Small Bodies .. ...

... Galileo Probe . The Galileo spacecraft was designed to study Jupiter's atmosphere, satellites, and surrounding magnetosphere for two years. ... From there, Galileo will spend more than five years traveling to Jupiter, where it will become the first spacecraft to make direct measurements from an instrumented probe within Jupiter's atmosphere. ... This image, taken by the Hubble Space Telescope, shows the predicted site at which the Galileo Probe will enter Jupiter's atmosphere on December 7, 1995. ...

... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...
