It is therefore important for spacecraft design to evaluate the impact risk by using environment models. In this paper, the authors compared the results of the debris impact flux in low Earth orbit, as calculated by four debris environment engineering models -NASA's ORDEM2000 and ESA's MASTER-2001, MASTER-2005 and MASTER-2009. The results reveal large differences in the flux estimation for debris larger than 1 mm and more than 100 microm in diameter., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065217000, レポート番号: JAXA-RM-11-020E}, title = {Comparison of Space Debris Environment Models: ORDEM2000, MASTER-2001, MASTER-2005 and MASTER-2009}, year = {2012} }
