... Ballistics, navigation and flight control of the spacecraft, going to the L2 point of Sun-Earth system. ... and calculation algorithms have been developed: - an algorithm, building nominal trajectories for one impulse flights to the L2 point of Sun- Earth system, including a Moon swingby maneuver or not. - an algorithm, calculating corrections of spacecraft trajectory needed for the flight from Earth to halo orbit and for stationkeeping of the spacecraft moving in halo ...

... Sternberg Astronomical Institute , Moscow University . ... Present edition unites two parts of Catalogue of interacting galaxies by B.A.Vorontsov-Velyaminov: the first part (Part 1) containing 355 systems was published in 1959 [1] and the second one (Part 2) with 497 objects - in 1976 [2].Thus two published parts of Catalogue include 852 interacting systems. ... All new of them (1162 by number) were taken from the comments to the galaxies in Morphological catalogue by Vorontsov-Velyaminov et al.[ ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
