MIRNEWS.141 29 JULY 1992 SOYUZ-TM15 DOCKED TO MIR: After an approach without problems the docking took place on 29.07.92 at 0749UTC. APPROACH: The first pass within our range was during orbit MIR 36883, 0738-0747UTC. Assisted by Avdeyev Solovyov reported to TsUP distances, approachspeeds and attitude angles and kept a manual control on the X-axis (roll). OPENING OF HATCH BETWEEN S-TM15 AND TRANSITION COMPARTMENT: During the next pass (orb. 36884, 0918UTC) the crews of both space-objects reported a perfect air-seal -S-TM15 still via 121.750 and MIR via 143.625 mc andithat they were ready to open the hatch. This happened a few seconds after LOS for our position. Just before LOS Kaleri got instructions to adjust the attitudeuts and complex for communications via the TDRS Altair. (So obviously the SUD -movements control system- is working well.) COMMUNICATIONS VIA ALTAIR: After 0930UTC for a long time monitored by OM Peter. He observed TV as well as voice communications and was witness of the coming in os and new crew and the French guest-spationaute Tognini and ts and conversation between Tognini and president Mitterand. During the passes in orb. 36886 (1226UTC) and 36887 (1404UTC) the VHF on 143.625mc was in use again. EXPERIMENTS: Tognini did not let the grass grow under his feet and helped by his Russian colleagues het installed the equipment for the experiments Viminal and Alice. A lot of more experiments will have to be carried out by Tognini, i.e. Orthostatisme (study of bloodcirculation), Viminal (influence of micro-gravityutn image- and impression processing, Illusions (mechanisms nervesystem and sensoro-motorism), Biodose (influence of cosmic radiation during spaceflights), Nausica (somewhat like Biodose, but concentrated on radiation doses in different compartments, Immunologie (influence micro-grav. on immunesystems human organism.), Alice (behaviour of liquids), Supraconducteur (crystall-growth in micro-gravity with the use os and Krater oven, Exeq (influence of ions on micro-processors and Micro-accelerometre (new device based on modern technologyuso better than the m.a.m.-s used thusfar.) DURATION OF TOGNINI's FLIGHT: Tognini will return to earth with Soyuz-TM14 on 10.08.92 together with Viktornko and Kaleri. Chris v.d. Berg, NL-9165/A-UK3202.
