JULY 1999

2nd spacewalk (EVA) 27th Main Expedition MIR:

This time Afanasyev and Avdeyev 'walked' in open space and Haignere =
stayed inside to lend assistance, act as  a liaison between TsUP and his =
comrades outside  and to make video and photos.
The exit hatch of the Sh.S.O. (airlock of the Module-D) was opened 9 =
minutes before the scheduled time. So for a while some profit of time, =
but all activities during the EVA lasted longer than planned and so  did =
the EVA.  The hatch swung open at 1106UTC and was  closed behind the =
cosmonauts at 1713UTC, so a duration of 6 hrs and 7 minutes, 28 minutes =
longer than had been foreseen in the original plan.=20

The number of tasks was quite substantial and not all of them could be =
accomplished.  One item had been added to the schedule, i.e. the search =
for an air-leakage  in the hull of the module Kvant-2 (Module-D).  We =
still remember how difficult it was to find the leakage in the hull of =
the module-O (Spektr) during EVA-s and also with the help of gaseous =
dyemarkers for observations from departing Shuttles,  and so it is not =
difficult to conclude that this task would be a mission impossible.  The =
fact that the cosmonauts at least had  to give it a try clearly =
indicates that specialists at TsUP consider the leakage, though very =
small, to  be a serious problem.  Ultimately they did not find the =
leakage.=20

A lot of time was consumed during attempts to deploy a new system for =
the deployment of antennae for satellites. This antenna was a =
Russian-Georgean project. The parabolic reflector antenna  had to be =
installed at the Sofora girder and deployed with a remote control.  =
Afanasyev was able to open the antenna for 80 or 90%. During the =
following EVA the cosmonauts will try to achieve 100%. If they do not =
succeed the antenna they will get rid of it.=20

During the EVA the cosmonauts had to retrieve some experiments from the =
outersurface. They succeeded to do so with the experiments Exobiology =
and  Dvikon.=20
Exobiology  is a study to determine the possibility for survival in open =
space of  organic samples wrapped up in meteoritelike materials. Dvikon =
is a study to determine and measure the  effects ot the exhaust of MIR's =
engines on  materials nearby.  Due to lack of time they did not try to =
retrieve the experiment Spica.=20

The EVA ended in a great hurry due to a failure of the thermoregulation =
in the spacesuit of Afanasyev. A filter was overheated.=20

Communications: A serious handicap for cosmonauts who have to do EVA-s =
is the fact that there is not a single geostationary communication =
satellite available.  A lot of crucial activities they had   to do when =
they were out of range of groundfacilities, for instance the opening of =
the exit hatch. The communications between MIR and TsUP took place on =
143.625 mc (UKW-1) as well  as on 130.165 mc (UKW-2).  As always during =
EVA-s 7 kc/s lower than normal.=20

When MIR came in range during orbit 76715 at 1640UTC, the hatch was =
still open. During the first passes within my range TsUP and the =
cosmonauts experienced a lot of noise caused by cross modulation from =
air-traffic control centers. So the help of Haignere as a relaystation =
was very useful.=20
 The cosmonauts got orders to close the hatches between the air lock and =
the P.N.O. and the P.N.O. and P.G.O (respectively the =
scientific-instrument compartment and the instrument-cargo compartment) =
of the module which is leaking air, Module-D.=20

3rd EVA:  This EVA is scheduled for 28.07.1999 between 1020 and 1530UTC. =
 Which of the Russians will make this EVA together with Haignere was not =
yet known during the hard  disc preparation of this report.=20
