Navy Missile Hits Decaying Satellite Over Pacific American Forces Press Service
WASHINGTON, Feb. 20, 2008 – A network of land-, air-, sea- and spaced-based sensors
confirms that the U.S. military intercepted a non-functioning National
Reconnaissance Office satellite which was in its final orbits before entering the
earth's atmosphere. 降下中の衛星の破壊に成功しますた。
At approximately 10:26 p.m. EST today, a U.S. Navy AEGIS warship, the USS Lake Erie
(CG-70), fired a single modified tactical Standard Missile-3 (SM-3) hitting the
satellite approximately 247 kilometers (133 nautical miles) over the Pacific Ocean
as it traveled in space at more than 17,000 mph. USS Decatur (DDG-73) and USS
Russell (DDG-59) were also part of the task force.

The objective was to rupture the fuel tank to dissipate the approximately 1,000
pounds (453 kg) of hydrazine, a hazardous fuel which could pose a danger to people
on earth, before it entered into earth's atmosphere. Confirmation that the fuel
tank has been fragmented should be available within 24 hours.
衛星には453キロのヒドラジンがあった。
Due to the relatively low altitude of the satellite at the time of the engagement,
debris will begin to re-enter the earth’s atmosphere immediately. Nearly all of
the debris will burn up on reentry within 24-48 hours and the remaining debris
should re-enter within 40 days.
低高度の衛星破壊の為、発生するデブリは多くが24-48時間で降下燃焼、残るものは40日
以内に降下する。
DoD will conduct a press briefing at 7 a.m. EST to provide further information
related to the operation. The briefing can be viewed live on www.Defenselink.com
through the Pentagon Channel. 後ほど記者会見を行なう。
