Educator's Guide to Micrometeorites . ... They are actually small bits of rock and metal that collide with Earth's upper atmosphere and, because of friction, burn up. On rare occasions, man-made satellites and spacecraft parts fall into the atmosphere and burn up the same way. ... That is what is happening to the particles in the upper atmosphere. ... Most meteorites fall into Earth's oceans. ... There is an easy way to collect meteorites, but we must be satisfied with finding small metal ones. ...

... In the presence of only uniform magnetic field B , the motion of a charged particle can be described with gyration about the guiding center and motion along the field line. ... In the precence of both magnetic and electric fields, the equation of motion for charged particle (mass m, charge q) is m d v /dt = q ( E + v x B ). ... Because v is independent of the mass and sign of the charge, it is the same for negatively and positively charged particles, and does not create electric current. ...

Saturn is a big planet, about nine times as wide as the Earth, so the rings are huge. Let me put them into scale, if Saturn and the rings were moved so that one edge of the rings touched the Earth, then the distance across the rings to the opposite edge would extend more than halfway to the Moon. ... Saturn has a lot of moons. ...

... Particle Sizes in Saturns Rings . ... Credit Copyright: RSS , JPL , ESA , NASA Explanation: What size particles compose Saturn's rings? To help find out, the robot Cassini spacecraft now orbiting Saturn broadcast radio waves of three different wavelengths right through the rings to Earth earlier this month. The experiment was sensitive to ring particle sizes because ring particles much larger than a broadcast radio wavelength will reflect those radio waves away. ... NASA Official: Jay Norris. ...

... Particle Sizes in Saturn's Rings . ... Explanation: What size particles compose Saturn's rings? ... The experiment was sensitive to ring particle sizes because ring particles much larger than a broadcast radio wavelength will reflect those radio waves away. ... The white center of Saturn's B-ring indicates that the density of ring particles was too high to make a good determination. Other radio observations indicate that some ring particles can be as large as several meters across. ...

The classic solution for homogeneous sphere was suggested in 1899 by A.E.N. Love [ 330 ], in 1908 by G. Mie [ 342 ] and in 1909 by P. Debye [ 199 ]. ... Traditionally the theory of light scattering by a sphere is called the Mie theory. ... The exact solutions of the Mie problem for an optically active sphere (i.e. a sphere of optically active material [ 7 ]) and for a sphere with an optically active mantle were first obtained in 1974-5 by S. Bohren [ 158 , 159 ]. ...
