... Parameters of the Moon-perturbed orbit . ... From orbits consistent with this limitation and with the date of the launch October 1, 2000 as an example, an orbit was selected with apogee directed to the North Galactic pole at the begining and rotation of orbit plane was maximized. The initial state vector is given in the inertial coordinate system in epoch J2000.0. ... The orbit has initial perigee radius Rp=7000.0 km, initial apogee radius Ra=343000.0 km and initial period T=8.453 days. ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

The problem of solar wind data correlation for the observations onboard several spacecraft is very important for three points of view: . ... This problem is studied now in detail by systematic determination of ion flux and ion velocity data correlations by INTERBALL-1 (IKI group), WIND and IMP 8 (both - MIT group). ... Solar wind plasma correlation lengths from IMP 8, WIND and INTERBALL-1. ... Correlation of solar wind observations onboard several spacecraft: INTERBALL-1, IMP 8 and WIND data. ...

God Science Forum Message . ... The Destropic Principle . ... Abstract: The “Destropic Principle” is an argument that establishes that every universe is equiprobable, and the possibility of life is not a more special feature than any other. This opposes to the “anthropic principle” when it is used to argue that there is a necessity for a divinity, or multiple universes, in order to explain the configuration of our universe, particularly, the capability of harboring life. ... www.astronomy.net . ...

THE PHOTOMETRIC RESEARCHS OF THE MERCURY'S SURFACE BY MEANS OF DIGITAL MODELS. ... The surface brightness of Mercury was measured Danjon (1933, 1949, 1953) and Harris (1961) in phase angle 3o-123o. The analysis of the various data of the integral photometric gives the results of determination of the main photometric constants for Mercury. ...

... 09.03.2001 . ... March 09 2001 09:00 (Moscow time) . The operations scheduled on OC "Mir" for March 8 are complete. The recent telemetry data confirmed that the complex remains pressurised, the thermal mode is normal, the onboard systems perform norminal. Enough electricity is generated to maintain the onboard systems operation and measure orbit parameters. The OC "Mir" onboard systems were checked out, orbit radio monitoring performed. Currently, the OC "Mir" is in free drift. ...

. The station "Clementina". The station "Clementina", launched in January 1994, belonged to the apparatus of a new generation, made on the base of superlight materials. Besides the Moon's relief shooting this station measured the height of relief and thinkness of the Moon crust, the model of the gravitation field and some other parameters. Back .

The acquisition data base of meteorological temporal data including systematic and chronologic cataloque for Global Tropical Cyclogenesis (on the whole of World Ocean's aquatorium) for 1983-1992 time interval is developed and based on personal computer IBM PC/AT. ... The data base consists of the following units: 1. ... This data base offers a unique opportunity to analyze macro- and synoptic-scale temporal features of global tropical cyclogenesis as indivisible physical process. ...

Magnetic Stars, 2011, pp. ... We discuss our most recent determination of the rotational period from longitudinal magnetic field measurements and H variability -- the latter obtained from over a decade's worth of professional and amateur spectroscopic observations. ... We concluded that the dipolar field of HD 57682 is characterized by a polar strength of 1.7 kG, and a magnetic axis aligned within 10 to 50 of the rotation axis, depending on the inclination of the rotation axis to our line of sight. ...
