Looking at the tle's form this object, I don't think it will decay in the
next few hundred years.  If something happened to it, it will be failure(but
I can't confirm this at the moment)

Last elset still in 966X1011km orbit, no big change here except for some
elsets(96255,96263,96269,96277,96291 and 96325) with slightly higher n'/2
values.(due to luni-solar perturbations ?)
