Estimates of the total debris population > 1 cm in size run more than an order of magnitude higher, and there are many more < 1 cm. See, for example, http://apollo.cnuce.cnr.it/CODRM97/AAS98-173.html also www.navspace.navy.mil/factsheets/slep.htm which says, "Scientists estimate that lowering the space surveillance threshold to the 5-centimeter size will expand the space object catalog to more than 100,000 items." ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/sat/seesat/seesatindex.html
