Since launching to Jupiter requires high departure energy and the initiation of solar polar observation does not happen quickly, the author this year presents another idea of ballistic realization of them via multiple Venus swingbys and also multiple earth swingbys. This paper successfully concludes quick acquisition of them with significantly lowered departure energy with admissibly high inclined trajectory for frequent solr polar observation., 形態: カラー図版あり, 形態: CD-ROM1枚, Physical characteristics: Original contains color illustrations, Note: One CD-ROM, 資料番号: AA0064738002},
