Press release: March 18, 2001, 09:00 (Moscow time) [06:00 UTC]

The operation with OC [Orbital Complex] “Mir” scheduled for March 17 is
complete.

The recent telemetry data confirmed the OC “Mir” remains pressurized, the
thermal condition is normal, continues deceleration in the upper atmosphere.

The next status report will be issued on March 19.
