Any significant debris generating event would be covered in Orbital Debris Quarterly News found here: http://orbitaldebris.jsc.nasa.gov/newsletter/newsletter.html but I find nothing like this mentioned. The back issues are fascinating; see the January 2010 issue for interesting summary charts showing debris growth over the last 70 years. Debris from the deliberate destruction of Fengyun-1C will need 100 to 150 years to re-enter. In comparison, I understand that all debris from the deliberate destruction of NRO Launch 21 by the US on 2-18-08 re-entered within 1 year.

Not too reliable I suggest. I would expect loads of debris to appear on Space-Track if this was true. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@wanadoo.nl Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
