U.S. will try to shoot down spy satellite gone bad

February 15, 2008 4:30am

The ignorance shown by most of the posters is appalling.

First off, High school level Orbital math shows that it is impossible for an intercept of this nature to put debris into a higher orbit as orbit changes take TWO velocity changes. One to change the perigee, one to change the apogee.

Secondly, the SM3 missile that will be used to intercept the sat is a hit to kill. The SM3 can attain orbital altitude but has magnitudes less velocity than the sat. Imagine if you could throw a baseball high enough that high flying jet would fly into it. The damage to the jet would be because it is flying at 700mph & the baseball is essentially at rest. Using an SM3 to intercept a sat cannot add any velocity to the sat which will be deorbiting anyway within weeks.

Lastly, the reason everyone condemned the Chinese ASAT test is because their intercept took place at such a high altitude that debris will be a danger to spacecraft for thousands of years (http://meetings.aps.org/Meeting/APR08/Event/84079). Debris from the coming event will be gone within weeks.

Since boingboing seems to enjoy editing my post to remove all vowels & thus make it unintelligible, let me repost it again:

Hypocrites. The Serbs are again playing their favorite game: "pretending" to be victims while at the same time oppressing their smaller neighbors. Stop protecting your genocidal murderers like Mladic, the butcher of Sebrenica. Surrender him to the UN war crimes tribunal & let Kosovo vote freely for their independence. Maybe then the civilized nations of Europe will judge that you are worthy of joining us.
