 note = {メインベルト小惑星帯に属する小惑星を調査することで、太陽系がいかにして形成されたかがわかると考えられているため、小惑星帯は科学的に非常に興味深い。しかしそれらは望遠鏡で調べるには小さすぎるため、代わりに探査機を用いる必要がある。数多くの小惑星を探査できればそれだけ多くの情報が得られ、新たな発見につながるであろう。そこで本研究では、ふたつの場合において探査機が最多の小惑星とフライバイするための軌道を求めた。ひとつ目では軌道長半径がおよそ2.35AUの小惑星を調査対象とした(ケース1)。ふたつ目はすべての小惑星を対象としたが、そこでは独自の評価関数を用いて最多の小惑星とフライバイできる探査軌道を決定した(ケース2)。更に探査機を逆周回に投入する方法を定量的に求めた。, Asteroids in the Main Belt are said to have evidences of how the Solar System was formed, so they are really important for science. But it is not easy to investigate them by using telescopes, because they are too small to be examined sufficiently. One way to solve this problem is to send a space probe. The more asteroids are examined, the more discoveries can be gotten. In this present study, orbital elements of the space probe were optimized to meet as many asteroids as possible in two cases. In one case, asteroids whose semi-major axes are close to 2.35 AU (1 AU equals 1.5 x 10(exp 8)) km were targeted (case 1). In the other case, all asteroids in the Main Belt were concluded in the calculation where the original function was introduced (case 2). What is more, a quantitative way to throw the space probe into a clockwise orbit was gotten., 資料番号: AA0047897037},
