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.
After reading up on this technology, (see my earlier post on the missile technology) I suspect that we are much much further along then we're letting on. If we can launch these pop up vehicles from war ships, we probably have the capability of putting them into guardian orbits, at least for short term (a couple of days) missions.
This should get listed under “breaking news”
NW Hawaii sea Weather bouy still reports 2.6’ seas,5.7 intervals & 3/10 cloud cover
Is there some official Nasa or DOD website where we can get up-to-the-minute info on this? How will we know if it happens and/or the results?
Just SW of Sydney and down to 160sm and lowering
Agreed- can this be in Breaking?
Starting northbound leg now. Air warning red, weapons free.
I’m monitoring NASA TV, but no indication they will cover it live
Just east of New Caledonia.. and haulin a$$
As you said it's "the plan". Hope they also have contingency plans B, C, and D.
Operation “Burnt Frost” about to commence.
Radar Lock.. cooling sensors..
FYI— CNN just said they are “waiting for news in the possible Navy shoot down,” and will bring any news of it first. Probably true because Greta is doing her thing and can’t be bothered with anything that deviates from her script.
NASA not covering.
T-minus 7mins.. down to 155 sm
I really wish we could see this.
I’m waiting for the report on Pacific Radio - “Clean-up on isle 23, 24, 25, . . . 2186, 2187, . . .”, etc,etc,etc.
