本研究では、地球接近小惑星が地球に衝突することを回避する手段として、宇宙機を小惑星に衝突させて、小惑星の軌道を変更する手法を検討し、宇宙機が小惑星に与える速度増分の不�

Collisions between protoplanets, the dependence of the collisional cross section upon the impact energy

Autor: Noda, Akiyoshi, Emori, Hiroyuki, Nakazawa, Kiyoshi

Publikováno v: 第39回月・惑星シンポジウム = Proceedings of the 39th ISAS Lunar and Planetary Symposium. :158-161

Collisions between protoplanets are common events in the later stage of planetary formation process. Protoplanets grew into present planets through these collisional events. So it is necessary to obtain information about redistribution of mass and an

Orbital evolution of asteroid (25143) Itokawa

Autor: Michel, Patrick, Yoshikawa, Makoto

Publikováno v: 第38回月・惑星シンポジウム = Proceedings of the 38th ISAS Lunar and Planetary Symposium. :139-142

The orbital motion of Asteroid Itokawa is quite chaotic at present, and we cannot calculate its orbital evolution accurately more than about 200 years. Therefore we studied the orbital evolution of Itokawa by a statistical method and found that the f

Continuous reorientation of the early Moon as a consequence of a leading-trailing asymmetry in the cratering rate

Autor: Morota, Tomokatsu, Furumoto, Muneyoshi

Publikováno v: 第38回月・惑星シンポジウム = Proceedings of the 38th ISAS Lunar and Planetary Symposium. :76-79

Cratering rate on the early Moon was expected to have been extremely high and spatially asymmetrical between the leading and trailing hemispheres because of a fast orbital motion of the Moon. Morota et al. [2004] have suggested a probable model of ev

Petrogenesis of Apollo 14 crypt-mare basalt

Autor: Lofgren, Gary E., Arai, Tomoko, Takeda, Hiroshi, Miyamoto, Masamichi, Kojima, Hideyasu

Publikováno v: 第38回月・惑星シンポジウム = Proceedings of the 38th ISAS Lunar and Planetary Symposium. :88-91

Apollo 14 crypt-mare basalt clasts in a series of three polished thin sections of 14,305 polymict breccias are mineralogically studied in order to understand crypt-mare magmatism. This is the first report to show an evidence that the 14,305 oldest (4

In situ observations on impact vaporization of water ice

Autor: Sugi, Norio, Arakawa, Masahiko, Kouchi, Akira, Maeno, Norikazu

Publikováno v: 第28回月・惑星シンポジウム = Proceedings of the 28th ISAS Lunar and Planetary Symposium. :33-36

Impact vaporization of ice was an important physical process in the accretion of icy satellites because this process could cause the varieties of the bulk density of these satellites. Thus, we have developed a new experimental equipment to measure th
