Satellite could plummet to Earth

Thats only 2 days away

dingo,they want to start early, and avoid the rush. Let's hope they hit it the first time up; otherwise you will remain on pins and needles for the ensuing shots.

The SM-3 KW design features a large aperture wide field of view long wave infrared seeker that provides acquisition ranges greater than 300 km against typical ballistic missile threats. Seeker pointing and intercept guidance are supported by a production IFOG Inertial Measurement Unit and wooden round simplicity of the SDACS propulsion providing over 2 miles of terminal divert capability. The KW includes a fully encrypted data downlink capability for full engineering evaluation of KW performance and to support rapid kill assessment.

Discrimination algorithms enable defense systems to compare objects in a target scene to determine which to intercept. Increasingly complex threats with separated target elements, countermeasures, and debris, require advanced signal processing and discrimination algorithms to identify object features needed to provide robust target selection. SM-3 has flown and demonstrated fundamental discrimination capability for unitary threats.

Computer program design upgrades are in work to expand the current selection accuracy and add capability against more stressing unitary and separating target scenes using target features observed by the Aegis radar system and the KW LWIR seeker to optimize selection confidence. Leveraging off discrimination architecture used across Raytheon’s missile programs, SM-3 continues to evolve an integrated discrimination design for insertion with the current seeker design and each of the sensing and signal processor upgrades available to counter advancing threats.

Well I wont be leaving the house on thursday and as long as it doesnt fall on my house I should be right .




US vows to pay for satellite damage.

A little birdie told me that you never coughed up last time it landed on us

I think you have to spell your country name like this, Dingo, if you want any money from us:

I-R-A-Q


:crazy:

I hope this isn't gonna be "shock and awe" for the Aussies!!!

Amazing that there is always money for Iraq, but little, if any, for anything else that is absolutely needed.

We need to end the 200 billion a year cost of the War In Iraq.

We need to end the 200 billion a year cost of illegal immigrants.

Like I've said before, Buzz for Prez.

Buzz,
That is funny.
I hope mother earth is completely safe when this thing falls. Buzz, any chance it weill go into the middle of the ocean?

With the earth being mostly ocean, pm, it could do that easily on its own, but if we are going to shatter it into bits, and pieces, no telling where it all might end up. I'm hoping they begin releasing more technical details, as to the exact orbit, altitude, etc..

 

[philamena]

I hope they release more details too. This is scary.

They have done any number of these intercepts out in the middle of the Pacific over the last 15 years - the first successful one was 24 years ago with the Exoatmospheric Re-entry Interceptor Subsystem (ERIS) program.

Here's a link to some photos of the satellite in space, as well as on the launch pad. Some interesting discussion, as well.

The satellite is known as NRO L21, or USA 193. It was built by the United Launch Alliance, a company started jointly by Boeing and Lockheed-Martin.

It was expected to burn up in the atmosphere upon reentry until some smart cookie at NASA pointed out that the fuel tank was frozen solid and would likely survive intact. I don't think it can be predicted with any certainty where it will land until it is very close to the surface.

Oops, that is the old thread from last fall. Here's the current thread, entitled Defunct Spy Satellite Falling From Orbit -AP

Truly, the NRO L21, is the launch designation number. The bus (booster), so to speak, was built by United Launch Alliance. ULA contracts out their launch vehicle to put satellites into orbit. I think I remember this alliance beginning just before I retired.

Congratulations on your retirement, Buzz

United Launch Alliance was incorporated on December 1, 2006. The National Reconnaissance Office satellite which we are discussing failed moments after liftoff on December 14, 2006. If there was a solar array, it never deployed. Hopefully, there was no rtg (radioisotope thermoelectric generator) on board.

Interesting discussion over on nasaspaceflight.com, eh? Excellent informed debate on this topic. Are there any other sites which you would recommend? Cheers.

US to try satellite shoot-down Thursday

WASHINGTON (AFP) - The United States will take its first shot at an out-of-control spy satellite on Thursday, trying to knock it into the sea before it crashes to Earth, possibly causing damage, CNN news reported Monday.

A second attempt would be possible if the first misses, the channel said, citing military sources. Pentagon officials were not immediately available for confirmation.

Without intervention, the crippled satellite is due to break into the Earth's atmosphere on March 6 and crash down at an unpredictable spot, risking rupturing its tanks of toxic fuel, US authorities warned last week. A US warship will fire a surface-to-air missile at the satellite at a specific point in its orbit that ensures any Earth-bound debris will splash into the ocean.

The shoot-down plan drew criticism on Sunday from Russia, whose defense ministry said in a statement it looked like a veiled weapons test and an "attempt to move the arms race into space."

Can't believe Russia is saying that.
Why don't they help in shooting it down....
Putin makes bad decisions, remember the hostage situation when
so many children got killed?
