MIRNEWS.384 16 SEPTEMBER 1997 Priroda: Drying out of this module lasted longer than expected. In the evening of 11.09 Vinogradov collected 8 liters of condense water. Kristall: This module is dry. This is not the case with the SO (docking compartment) attached at Kristall. The crew supposed that they have to dry out this SO in the same way as they do with Priroda. On 14.09 TsUP asks Vinogradov whether the crew already used condensation for drinking water. Analyses of water samples delivered on earth on 14.08 should justify the potable use of water from condensation. Vinogradov said that they did not thusfar, but that they have used this water for the refilling of the Elektron. On 14.09 at 1028UTC the crew got orders to switch off the Ts.V.M.-1 (Main OBC). Telemetry indicated that 2 of the 3 channels (possibly interfaces) of that computer produced incorrect data. Due to the better charged accumulators this time the usual 'chain-reaction' was not as abrupt as during Ts.V.M.-1 failures in the past. Nevertheless the SUD, the attitude control, switched itself off and the gyrodynes slowed down and stopped. The Elektron, which consumes 1 Kw was switched off. The complex came in the so called 'free drift'. When on 15.09 the station passed over here for the 3d time in orb. 66107 (0509UTC) the cosmonauts had switched on the Ts.V.M.-1 as well as the SUD. This was only for a short period. Later on both systems were 'off'. The cosmonauts got permission to dismantle the computer and to replace some parts and/or accessories. At TsUP considerations were going on about the replacement of this computer by a reserve which has been in stock for a long time if the repairs might fail. At last the decision was taken to have the whole computer replaced and so the crew did. In the evening the cosmonauts rebooted the 'new' computer. In the night from 15 to 16.09 Solovyov was on duty while experts at TsUP loaded data in the computer. As soon as the computer was operational the attitude of the complex could be stabilised. On 16.09 at 02.15.03UTC the orientation was restored in such a manner that recharging of the accumulators could begin. Radiotraffic revealed that the situation was normalizing. A number of systems, among which the Elektron, remained off. For oxygen production the cosmonauts continued to use 'disks' (lithium perchlorate cartridges). The pressure of MIR's atmosphere was 618 mm mercury. More computer news: Progress-M36 has to deliver a brand-new computer in October this year. Chris v.d. Berg, NL-9165/A-UK3202.
