Space missions are an excellent way to increase our knowledge of asteroids. Near-Earth asteroids (NEAs) good targets for such missions, as they periodically approach the orbit Earth. Thus, increasing number NEAs being planned worldwide. Recently, NEA (153591) 2001 SN263 was chosen target ASTER MISSION – First Brazilian Deep Mission, with launch 2015. discovered in 2001. In 2008 February, radio astronomers from Arecibo-Puerto Rico concluded that is actually a triple system. The announcement...
The problem of changing spacecraft energy in minimum time near an oblate planet by means tangential low thrust is considered. mass ow rate and the exhaust velocity are assumed constant. Simple approximate formulas allowing calculation three-dimensional spiral trajectory obtained. rstapproximation more accurate second-approximation given. All valid both for ascent descent orbit. accuracy estimated; it shown that they provide high when acceleration much smaller than gravitational acceleration.
Attention is attracted to the idea of using magnetic flux trapping (MFT) HTSC as a memory medium (MM). From this point view writing-storage-reading-erasing' cycle was studied. Investigations feasibility in principle local writing and measurements MFT dependences on temperature, external field transport current have been performed. For YBa2Cu3Oy ceramics following values trapped fields were obtained: Hlt approximately=20-30 Oe at 77K; approximately=60 4.2 K, for films 4-9 Hlt>or...
This paper presents a handful of the underlying properties spacecraft’s transfer from low Earth orbit (LEO) to moon’s using an electric propulsion (low-thrust) system. The use analytical and numerical-analytical modeling in complex natural technical processes is key factor this issue Symmetry, which has been thoroughly explored paper. First, optimization problem was considered find locations lengths thrust arcs that maximizes final mass spacecraft for number orbits, thereby limiting scope...
