MIRNEWS.189 22 SEPTEMBER 1993 3d Spacewalk (EVA) put back: Until 22.09.93 the cosmonauts made preparations for an EVA on 24.09.93. During that EVA they had to execute the program 'Panorama', which is an inspection of the outersurface of the station by camera's. On 22.09.93 TsUP announced that the EVA had been put back to 28.09.93. A reason for the delay has not been stated. Possibly the unstable political situation in Moscow has something to do with it, but technical reasons are also possible. On 22.09.93 the crew worked on a problem with a pressure-valve (KVD) of the airlock (Sh.S.O.) in Module-D. MIR-station hit by a particle from outer space: On 21.09.93 at abt. 1205UTC, while the station was near the equator, Tsibliyev heard the clap of a particle colliding with MIR's outer surface. The impact caused a little cloud of dust and released some pieces of paint of the wall. Tsibliyev heard the impact while he was flying from Kvant-1 to the Base Block. Serebrov, who was working in Module-D, did not hear it. Chris v.d. Berg, NL-9165/A-UK3202.
