Soyuz TM-26 was a Russian spaceflight that ferried cosmonauts and supplies to Mir.

It was launched by a Soyuz-U rocket from Baikonur Cosmodrome on August 5, 1997.

The main mission was to transport two specially-trained cosmonauts to repair or salvage the troubled space station.

The crew repaired the power cable and harness/connectors in the severely damaged Spektr module and restored much of the lost power; they also repaired and replaced the oxygen generators in Mir.

During the flight a television advertisement starring Vasily Tsibliyev was filmed on the station.
