According to this link, China fired a missile to destroy an orbiting weather satellite last week: http://www.spacewar.com/reports/China_Tras...e_Test_999.html

I am curios about what kind of projectile could be used? A "smart" one with on board guidance system or just a dumb one? How close did the "killer satellite" came to the target?

Does anybody have an idea?

There was an article quoting unamed sources that there were three previous unsuccessful attempts.

Regarding detecting / tracking the ASAT engine plume, the ASAT would only need course correction maneuvers in the end game. These burns are relatively low energy. Early warning sats are required to detect rocket plumes during boost phase which are much larger. Whether their sensors are sensitive enough to detect small ASAT course correction burns is unknown outside the classified realm, but my guess is not likely.

Regarding staring sensors, the operational US early warning sats in geosynchronous orbit still use a scanning sensor. There have been tests of staring senors in add-on payloads to other military sats in high elliptical orbits. I don't recall reading that these are in operational use.
