美间谍卫星被击中

Decaying spy satellite USA 193 | Home |
USA-193 has now been hit by a missile fired from a US warship near Hawaii. The debris from the satellite will re-enter the atmosphere over the coming weeks. It is not yet known whether the hydrazine fuel tank was ruptured by the missile, which was the primary purpose of the firing.
LaunchUSA 193 was launched on December 14th, 2006 from Vandenberg Air Force Base in California. The launch vehicle was a Delta II. Shortly after reaching orbit, ground controllers lost the ability to control the satellite, and have never regained it.
PurposeThe exact design and purpose of USA 193 are, or course, closely guarded secrets, but specialists believe it is probably a high resolution radar satellite which was intended to produce images for the National Reconnaissance Office (NRO).
When and where will it hit the Earth ?Now that the satellite has been broken up by the missile collision, the debris will come down over wide area over the coming weeks as they are slowed by atmospheric friction. Re-entry will happen when the pieces reach about 100km. The plot below shows the decay of USA-193 before it was hit by the missile. “想看碎片吗?查看这里是否过你处”。。。
拉倒吧,轨道根数都还是19号的! 原帖由 活动星图 于 2008-2-22 05:44 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif

做梦吧,鬼才能告诉你每个碎片的根数 呵呵1361192.gif 哈哈 原帖由 ALMACH 于 2008-2-22 05:47 AM 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif

我还真没做梦,要不是它是保密卫星,每个碎片都有根数发布,风云一号就是一个很好的例子! RIM-161 (SM-3)
标准3导弹果然名不虚传啊……::070821_15.jpg::
从巡洋舰发射就可以拦截大气层外低轨道目标,那拦截战斗机是不是太轻松了……
中国的Su-27怎么突防啊…… 原帖由 Plane 于 2008-2-22 16:33 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif

据说巡洋舰发射SM导弹可是一秒一枚,一艘船有一百多枚呢,即使弄一个机群,也不是人家的个呀 所以要发展射程超过280公里的高超音速掠海反舰导弹,靠飞机过去投弹肯定都要被揍下来。 ::070821_09.jpg::
中国揍人家巡洋舰毫无疑问是用潜艇
再说了,反舰导弹用低弹道、超低空飞行他射程远管什么用 原帖由 沈阳-陈博丹 于 2008-2-22 16:54 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif

去看看Lock On 里面的标准1导弹的速度就知道了,基本是1km迎头做9G的机动可以躲掉
不过拦截KH41掠海反舰导弹不是那么容易。但是对于标准3就不知道了…… 原帖由 张紫恒 于 2008-2-22 17:28 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif
我国的超音速反舰导弹还是比较先进的~::070821_01.jpg::
目前只有进口俄方的反舰导弹可以胜任 原帖由 Bear2 于 2008-2-22 17:39 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif

前提是能够完整得逼近到敌方舰队附近 虽然是两天前的新闻...可现在变成导弹论坛了!!!::hairsmile:: 航空航天和天文是相通的吗~::070821_01.jpg:: 哎,人家造那么一堆潜艇,自有人家的办法
