The rate of rate of decay of USSTRATCOM's elements has settled down sufficiently to make initial estimates of decay dates. I used Alan Pickup's Satevo 0.51, with 10.7 cm solar flux of 69. Omid's (09004A / 33506) epoch 09034.82386470 elements yield estimated decay in mid June 2009. Omid rocket's (09004B / 33507) epoch 09034.76761317 elements yield estimated decay in late July 2009. This far in advance, the uncertainty is about one month.
