However, this is not the first spacecraft to use an ion source as the primary propulsion system. For some time thay have been used for orbit correction of geosynchronous satellites. The engine provides 10 times the specific impulse of chemical propulsion. Therefore ion propulsion systems reduce the weight and cost of carrying propellant. in this paper the physical basics of such systems are described</dc:description><dc:description xml:lang="sl">Pred kratkim je ameriška vesoljska agencija NASA poslala v vesolje sondo Deep Space 1, ki jo poganja ionski izvir. To pa ni prvi primer uporabe ionskih izvorov za pogon vesoljskih plovil. Že dlje časa jih uporabljajo tudi za korekcijo orbite geostacionarnih satelitov. Ionski izviri dajejo specifične impulze, ki so 10-krat večji od tistih, ki jih dobimo s pogonskimi sistemi na osnovi kemijskih goriv. Zato tak način pogona vesoljskih plovil zmanjšuje maso in ceno potrebnega goriva. V prispevku opisujemo osnovne fizikalne zakonitosti, na katerih temelji delovanje ionskih izvirov za pogon vesoljskih plovil</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-HT6VHUCC"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-HT6VHUCC" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-HT6VHUCC/c3592028-bcdf-4587-af93-9d04b528642f/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo za vakuumsko tehniko Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-HT6VHUCC/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-HT6VHUCC" /></ore:Aggregation></rdf:RDF>
