... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...
