Soyuz TM-25 docked with Mir at the forward port on February 12 at 15:51:13 GMT. The EO-22 crew of Korzun and Kaleri, together with Ewald, undocked from Mir in the Soyuz TM-24 spaceship at 03:24 GMT on March 2 and landed at 06:44 GMT near Arkaylk in Kazakstan.
AKA: Sirius (Sirius ); Soyuz TM-25 (Ewald).
First Launch: 1997.02.10.
Last Launch: 1997.03.02.
Duration: 19.69 days.
Communications Soyuz-TM25: 3 hours after launch on 10.2.97 (orb. 2, 1712-1714 UTC) the transmissions of the ship could be monitored on the well known frequencies with Tsibliyev on 121.750 mc with TsUP. During the next pass (1841-1848 UTC) he reported the good results of the 2 orbit corrections. He also mentioned some problems with a TV-installation or a screen. Apart from some interference by the ground services of a near by airport (also using 121.750 mc, but AM-W) the signals came in loud and clear. Also during the second day (11.02.1997) traffic could be heard during all passes for our position.
Communications Mir: On 8.02.1997 DLR's GSOC in Oberpfaffenhofen (Germany) and Mir tested the direct link via the quasi-geostationary comsat Altair-1 over 16dgs West. Good images and audio from inside Mir demonstrated that the test was a great success. They also checked the performance of the so called BDD (Betriebstechnik Deutschland Direkt). This is an interface assembly for direct data exchange between specialists on earth and Reinhold Ewald during experiments in the framework of the Mir-97 program. A few days later it was clear that the direct link between GSOC and Mir will be a normal routine until 2.03.1997 (the end of Mir-97).

Anniversaries: On 20.02.1997 Tsibliyev celebrated his 43d birthday. Exactly 11 years ago the Base block of Mir was launched. . Problems with a gyrodyne: On the eve of these anniversaries the crew had to solve a difficult problem. On 19.02.1997 during the pass in orbit 62876 (1521-1527 UTC) TsUP gave Korzun data, which had to be loaded in the system Svet for the movements control of the complex. Korzun asked what the reason was. TsUP informed him that Telemetry showed the malfunction of a gyrodyne in Kvant-2 (Module-D). In the evening and night the crews solved the problem.
Communications: Contrary to the expectations the German GSOC Oberpfaffenhofen seldom uses the possibility for direct links with Mir via the (almost) geostationary Altair-1 (Cosmos-2054). Apart from the 143.625 mc, Ewald regularly uses the so called UKW-2 (VHF-2) on 130.165 mc for communications with his consultants (Sigmund Jähn) at TsUP and (Hans Schlegel) in GSOC. Now and then Linenger can be heard on that frequency with the American consultative group at TsUP . The 145.800 mc is the downlink frequency for Packet radio or phone. Mostly Korzun can be heard here. A few times Ewald uses this facility for contacts with German radio-amateurs. He uses the call sign DL2Mir. In the simplex mode he sometimes can be heard on 145.925 mc.

Last week of Mir'97 and Main Expedition Mir 22:
The fire in the night from 22 to 23.02 put its stamp on this last week due to the pollution of the Mir's atmosphere during the first days and the extra attention the crew had to give to the damaged oxygen-generator and cables. For a long time there was the smell caused by the fire. One of the cosmonauts spoke about the smell of 'roasted turkey'. Some crew members suffered from some irritation of the bronchia, a dry throat and sleeping problems. Nobody was hurt with the exception of Korzun who had a very small burn on his hand. Ewald had already executed the majority of the Mir'97 experiments and the events did not significantly influence that program. German project managers were satisfied about the successful results and conclusion of the mission. During this week there has been a lot of radio traffic on 2 frequencies simultaneously: the Russians used 143.625 mc and Ewald and Linenger 130.165 mc. For some planned TV sessions, i.e. for the RTL children's programme Captain Bluebear and about a contest for drawings by children with the wife of the German President Herzog they did not use the geostationary satellites but direct TV transceivers on lower frequencies. For phone during these sessions Ewald used the UKW-2 130.165 mc.
Siriusses: The new crew, Tsibliyev and Lazutkin, the 23d M.E. to Mir, and Jerry Linenger will have to do a lot of work in the near future. In fact there are still a lot of experiments in the framework of Mir'97 to be done: this had been planned and this work got the designation Mir'97E, the letter 'E' standing for 'Extension'.
Progress-M33: This old freighter is still flying autonomously until her 2d docking at Mir. That will take place on 4.03.97. Tsibliyev got orders to control the approach and docking manually with the remote-control system TORU. There has also been an instruction to leave Progress-M33's hatch closed after docking. Kaleri asked TsUP to consider the possibility to open the hatch and to use the still available room in the spherical part of Progress-M33 to stow stuff no longer needed: especially the considerable amount of human waste. During the long period with a crew of 6 the quantity of this increased enormously.
