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? |

Anybody know what the inclination of the target satellite's orbit was? I got a sinking feeling that it might well have been in a polar orbit...worried a bit about the NOAA polar orbiters & that debris cloud...
EDIT: Yep, it was in a polar orbit, but a bit below the NOAA POES... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I got a sinking feeling that it might well have been in a polar orbit...worried a bit about the NOAA polar orbiters & that debris cloud... EDIT: Yep, it was in a polar orbit, but a bit below the NOAA POES... According to Jonathan's Space Report ( http://www.planet4589.org/space/jsr/latest.html ): The FY-1C was in an 843 x 862 km x 98.7 deg orbit; the debris cataloged so far ranges from 165 x 850 km to 850 x 3500 km, a wide range of heights indicating an energetic fragmentation with delta-Vs of -190 to +550 m/s. Of course, we are missing the tail of dV significantly less than -190 since those objects would reenter immediately. Correct me if I'm wrong, but doesn't this put ALL satellites from 165 to 3500 km at risk and not just the ones around 850 km? |
