WHAT IS THIS?

No, it's not a run-a-way spacecraft from the outer limits. But it does have something to do with space.

It is the Raytheon-Boeing X-Band radar that sits atop a converted sea-based oil-drilling platform and will be used to help direct the Pentagon's "missile offense" program.

The $900 million X-Band radar was just towed into West Seattle (Washington state) for repairs before it heads back out into the Pacific Ocean where it will do its work.

There appears to be an effort underway by activists in the Seattle area to organize protests against this expensive and provocative system that is driving a new arms race into space.
