Soyuz TM-28 docked at 10:56 GMT on August 15 with the rear (Kvant) port of the Mir space station, which had been vacated at 09:28 GMT on August 12 by Progress M-39. The EO-25 crew, Musabayev and Budarin, landed with Baturin on Aug 25, leaving the EO-26 crew of Padalka and Avdeyev on the station. As only one final Soyuz mission to Mir was planned, with two of the seats on that Soyuz pre-sold to Slovak and French experimenters, the return crew of Soyuz TM-28 was subject to constant replanning and revision. On February 8, 1999, at 11:23 GMT Padalka and Avdeyev undocked from Mir's -X port in Soyuz TM-28, and redocked at the +X Kvant port at 11:39 GMT, freeing up the front port for the Soyuz TM-29 docking. Finally on February 27, 1999 EO-26 commander Padalka and Slovak cosmonaut Bella undocked Soyuz TM-28 from the Kvant rear docking port at 22:52 GMT, landing in Kazakhstan on February 28 at 02:14 GMT. Avdeyev remained on Mir with the EO-27 crew delivered on Soyuz TM-29, heading for a manned space flight time record.
