The satellites are covered by nearly 1000 small, front-surface aluminum mirrors that are machined by technology students in Utah and polished by tens of thousands of students all over the world. ... And this is only small story about it. ... We will be able to measure the angular position of that satellite by observing sunlight flashes from small mirrors mounted on the surface of the satellite, as it passes across the starry sky before sunrise and after sunset.. ...

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

How the rings were formed. ... Because of the velocity of mutual collisions increases at the approaching to the planet, there is a region near an every planet where the particles reaching the definite sizes begin to pull due to the mutual collisions. ... Any big particle passes the whole cycle from the destruction to the restoration. ... Why the rings are so flat? ... The gravitation compresses the system from all sides and the rotation axis, but it cannot prevent compression along the axis. ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...
