. Authors . Problem . Method . Advises . Contact Analysis of an accuracy of CCD asteroid observations carried out by professional and amateur astronomers . An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400
... В наши дни невозможно представить себе жизнь без услуг космических систем связи и телевидения, навигации и спасения. Их создание вплотную связано с деятельностью коллектива Научно-производственного объединения прикладной механики (НПОПМ), до недавнего времени возглавляемого действительным членом Российской академии наук, одним из ведущих ученых и организаторов в области космического машиностроения Михаилом Федоровичем Решетневым. ...

ПОЧЕМУ МАРС? ... В космическом центре JPL (США) построена модель гравитационного поля Марса, «Mars 50с», в которой разложение гравитационного потенциала планеты по сферическим функциям доведено до 50-ой гармоники [24]. ... В противоположность этому, Марс, начиная с Хесперийской эпохи (1.8 млрд. лет тому назад), стал весьма не похож на Землю, когда скорость процессов эрозии стала очень низкой, и она с тех пор привела к малым изменениям поверхности в месте посадки КА «Марс Пасфайндер». ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
