<p>好就是好 不好就是不好</p><p>日本拥有独立开发大推力运载火箭的能力,各种卫星漫天飞</p><div class=\"t_msgfont\" id=\"postmessage_15625131\">“月亮女神”,轨道机动在日本时间4号6:20分进行,都已经进入月球轨道了,现在的轨道参数11741x101km<br/><br/>JAXA performed the lunar orbit injection maneuver (LOI1) for the “KAGUYA” (SELENE) at 6:20 a.m. on October 4, 2007 (Japan Standard Time, JST.) As a result of the orbit calculation after the maneuver, we have confirmed that the KAGUYA was injected into the following lunar orbit. <br/>Injected orbit:Apogee altitude 11,741 km, Perigee altitude 101 km<br/>The satellite is confirmed to be in good health.<br/>We are now pleased to be able to report to you that we have safely delivered messages and signs that were collected from 412,627 people around the world through the Wish upon the Moon Campaign and engraved on the sheets to be aboard the KAGUYA to the Moon. We would like to express our profound appreciation to all perticipants and hope your continued support to the KAGUYA mission.</div><p>你的例子实在是延迟的厉害,日本不能永远当反面例子用</p><p>德国的份额再高,不过是局部技术的先进。航空上,没有自己独立的航空发动机,航天上没有自主的大推力运载火箭,就此2点就足够致命了</p><p>航空航天的竞争是一个系统工程,不是比谁的光学镜头买的多</p><p>航天技术,老大是美国,其次是前苏联,然后是法国、其实是欧空局,之后是中国,日本。其他国家根本没有自己独立的体系,无论搞什么都靠着前面的几个大国干,要排队都得往后</p>
