... Courtesy of NASA's National Space Science Data Center . Originally designated the Pluto Fast Flyby (PFF), the Pluto Express mission is planned to be a two-spacecraft mission designed to make studies of the planet Pluto and its satellite Charon. Its major science objectives are to: (1) characterize the global geology and geomorphology of Pluto and Charon; (2) map the composition of Pluto's surface; and, (3) determine the composition and structure of Pluto's atmosphere. ...

The global analysis of the Earth linear structure elements has allowed to define the position of geographical poles in the different geochronological periods [3, 4]. ... It is the curves that unite sequences of geographical poles - poles of symmetry of faults in the global stress field fixed by faults on a surface of the mantle during its rotation around of the core. ...

... The planets differ greatly in size and properties, and their fields differ too. ... In 1959, after the Earth's radiation belt had been discovered, Frank Drake observed Jupiter and concluded from the relative intensities in a range of wavelengths that the signal was probably emitted by electrons trapped in a strong magnetic field. Then in 1973 the space probe Pioneer 10 passed by Jupiter and found there, sure enough, an enormous planetary magnetic field and a very intense radiation belt. ...

... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

... Since planets are expected to form out of the material in disks around young stars, the formation of a planet will thoroughly alter the structure of the circumstellar disk of their host star, forming significant gaps in the radial distribution of matter around the star. Additionally, processing of solids (annealing/crystallization) and changes in the overall gas/dust ratio are thought to happen during the planet formation process and are believed to alter the observational signature of the disk. ...

Europa ("yoo ROH puh") is the sixth of Jupiter 's known satellites and the fourth largest; it is the second of the Galilean moons. ... Discovered by Galileo and Marius in 1610. ... But Europa's surface is not at all like anything in the inner solar system. ... The images of Europa's surface strongly resemble images of sea ice on Earth. It is possible that beneath Europa's surface ice there is a layer of liquid water , perhaps as much as 50 km deep, kept liquid by tidally generated heat. ...

... In summer 1994, the biggest news in astronomy was the collision of comet Shoemaker-Levy 9 with Jupiter. During this school year, Jupiter will charge back into the limelight with the arrival of the Galileo spacecraft (see figure 8 ). On Dec. 7, following a tortuous six-year ramble through the solar system, Galileo will begin its two-year mission studying Jupiter and its gaggle of moons. ... Besides the camera, Galileo will carry instruments capable of identifying minerals on Jupiter's moons. ...

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms.
