According to reports in the last couple of weeks, the planned lowering 
of Mir's orbit (over the next 6 months) using the Progress M-39 by the 
end of June 98 has been delayed due to the next launch of Progress M-40 
moving from August to Sept 98. I suspect there are no plans to boost the 
orbit. Glitches, I suspect.
