WASHINGTON, Feb. 20, 2008 The Pentagon has opened the window of time in which it will shoot down a malfunctioning U.S. reconnaissance satellite, a senior U.S. military officer said here today.
Todays return of the space shuttle Atlantis to Earth prompted the start of the optimal time period for shooting down the satellite, which extends until about the end of the month, the senior officer told Pentagon reporters.
Only tens of seconds will be available each day for a favorable launch of a ship-based SM-3 interceptor missile, the senior officer said. The window is small, but were looking for the best orientation of the satellite before launching the missile, the officer explained.
The 5,000-pound satellite malfunctioned soon after it was launched in 2006, making it unresponsive to ground control. It is carrying a tank full of hydrazine, a toxic rocket fuel. The satellite, orbiting every 90 minutes or so, was expected to fall to Earth in February or March with its tank of hydrazine intact, possibly endangering human populations.
President Bush directed the Defense Department to engage the satellite just before it enters the atmosphere at about 150 miles above the Earth. The goal is for the missile to hit and rupture the tank of rocket fuel, causing the hydrazine to burn up harmlessly in the atmosphere, along with debris from the stricken satellite.
About 50 percent of debris produced by the missile strike is expected to burn up during the stricken satellites first two orbits after being hit, the senior military officer said, with the rest burning up shortly after. The strike is designed to leave no space debris.
Defense Secretary Robert M. Gates is to give the order to launch, based upon commanders recommendations, the senior officer said. Gates will be advised as to the optimal time to launch by the commander of U.S. Strategic Command, based at Offutt Air Force Base, in Omaha, Neb.
All space sensor and missile-tracking activity related to the missile launch is being coordinated by the Joint Space Operations Center, at Vandenberg Air Force Base, Calif. Sensors, such as large radars and telescopes, are being coordinated by the Joint Integrated Missile Defense Team in Colorado Springs, Colo., under the U.S. Armys Space and Missile Defense Command.
Three U.S. Navy ships -- the cruiser USS Lake Erie and the destroyers USS Decatur and USS Russell -- are posted in the Pacific Ocean waiting for an optimal time to launch, the senior officer said. The Erie is slated to shoot at the satellite, and it is fitted with two SM-3 missiles. The Decatur has one, and the Russell has none. The missiles were modified to carry additional sensor equipment for the mission, the senior officer said.
The launch will be conducted during daytime over the Pacific, the senior officer explained, so that all sensors involved can better track the results of the missile launch. Necessary criteria for launch include satisfactory alignment of all pre-launch sensor-supplied data, as well as favorable weather conditions, he said.
Currently, the wave height about the ships is unfavorable to launch, the officer said. However, this and other conditions are subject to change, he added.
This isn’t an issue when going up against non-state foes, but if we should have to confront any major power, you can see what the first targets are going to be.
Punch out your enemy’s satelites, and you’ve punched out his lights.
I’m sure there are smart people thinking about this, on both sides.
It's called land debris when it crashes into your backyard.
I think they’ll nail it. First shot.
Hope so,.. son is an civilian aerospace engineer on the project.

I'm an engineer and was just thinking about how kewl it would be to work on a project like this. Big props to your son.
Let’s do this!!!!!!
Jeepers it has been an exciting day. The shuttle landed. Eclipse in a few hours. And shooting down the satellite!
If they miss, and you see the missile or the satellite headed for you in a fiery ball, put your head FIRMLY between your knees, and kiss your ass good bye!
my bad
My husband is an engineer. Dow Chemical Co. 35 years.
Kick the tires and light the fires!!
OUCH! We just finished remodeling, took EIGHT months! I hope we don’t get zapped by it. It was neat living in So. Cal. sometimes you could see the fireworks when they shot down a missile during testing. I think from vandenberg AFB
Who’s going to start a live LUNAR ECLIPSE + ASAT popcorn thread?
YOU CAN! I will go get the beer!
Who has clear skies for the eclipse? it is raining here in Houston and on the coast. DRAT
Looking at the map, it looks like they’ll have a chance on the next orbit.

. . .
How long will it take for the moon to be encircled with satellite traffic like Earth? Not very long, with the current moon rush. By the end of 2011, nine satellites could be buzzing around up there.
So we might get an artificial meteor shower out of this?
