MIRNEWS.366 1 JULY 1997
Radiotraffic in the period 26.6 - 1.7.1997:
During this period it was for me a relief when I during the first pass of the
daily sequence heard the voices of the c rew. Every conversation between
the crew and TsUP referred to the difficult situation and their 'struggle for
life'.
26.06: Just like on 'collision day' they again had to do everything to adjust
those solar-arrays which still were opera tional to the best angle towards
the sun. The absence of the gyrodynes for the movements control and the
absence of t he possibility to have commands executed by computer programs
means that the crew has to adjust the solararrays manuall y. One of the
complaints was that the solararrays on Module D moved very slowly.
Nevertheless the angles towards the s un gradually improved leading to an
increase of power supply. The crew did all what was possible to determine the
dama ge by observations and making images via several portholes, but it was
impossible to get a full picture. For the recept ion of radiograms the RTTY
system was in use again. The attitude control of the complex was executed by
thruster jets, also with those of the transportvehicle Soyuz-TM25. They did
not do any experiments for which electrical energy was ne eded and all
radio-amateuractivities had been suspended. For the filtering of the air
from CO2 now and then the Vozduk h scrubber was activated.
27.06: This day there was word about a gyro-stabilized orientation, possibly
with the attitude control of the S-TM25. For the neutralization of CO2 TsUP
wished the use of lithium hydroxide canisters. Tsibliyev asked permission to
do this
with Vozdukh. At first they had to do this with those canisters, but later
on they got permission to switch on Vozdukh
for a while. The crew also worked on the Elektron, but this oxygen producer
had to remain switched off to economize e nergy. During the pass in orb.
64863 there has been a TV-link (Anna-72 and Anna-86) and possibly they used
for the pho ne during these communications the VHF-2 130.165 mc. During the
pass in orb. 64865 the crew answered questions of a l ady on earth. The
crew said that only a few experiments ('sleep' and the 'orangery') can be
executed. During this inte rview the possibility of a spacewalk (EVA) was
mentioned. Tsibliyev spoke about an 'internal' EVA. Tsibliyev hoped that
their spacesuits will enable them to enter the Spektr. He stated that the
present situation is far from hopeless. Pro blem is that 1 solararray has
been severely damaged. The other 3 solararrays on Spektr are still in good
order, but it
is a 'bloody shame' that they cannot deliver electrical power. One of those
3 is badly needed for the powersupply. Th e lady asked how things are
looking inside the Spektr. Tsibliyev said, that they do not know this for
they have not be en inside. In his opinion a spacestation can be compared
with a 'test firing range' where everything is possible. They
are very proud of their MIR. Cosmonauts are prepared to undergo normal and
emergency situations, even those which have
not been foreseen. But together with the experts on earth they always will
'twist themselves out'.
28.06: Today again attitude corrections with the thrusters of Soyuz-TM25.
Also a few times TV-links. The work on the E lektron has been postponed until
next Monday, probably due to a valve that cannot be opened. Later on they
spoke about
the functioning of the Elektron in Kvant. (37KE). Today the transfer of
radiograms with Packet Radio could be monitor ed.

A lot conversations about the 'internal' EVA. The equipment needed for this
EVA has to be transferred from the Sh.S.O. (airlock of Module-D) to the
P.Kh.O. (transitionsection, which again has to function as airlock). They
spoke about the
spacesuits, POV, BSS and so on.
29.06: During passes they almost exclusevily spoke about the next EVA and
also mentioned the spacesuits which have to be used: Orlan-M or Orlan-DMA.
Foale is also involved in the solution of these problems. It was also
obvious that a p art of the available gyrodynes is functioning normally. Now
and then they speak about the switching off of one gyrodyne
or the use of a reserve.
30.06: Again a lot about the EVA. There was also work to do on the
coolingloops VGK and K.Okh-B in Kvant (37KE).
1.07: Foale spoke with Wendy Lawrence, his successor. He says that his
'little room is in vacuum now'. Meanwhile the radio-amateur Packet Radio
transmissions on 145.985 mc have been resumed. (this means that the power
supply situation really improved)
During the pass in Orb. 64925 Tsibliyev reports: 'At about 1100UTC we heard
some dull claps or knocks. It was not clear
what it was. When we at 1103UTC entered the light from the shadow we saw a
big cloud of very little white flakes nea r the Module-O (Spektr). Obviously
there is fuel leaking away from somewhere'. He asked TsUP to check the
fueltanks b y Telemetry.
That's all for now folks.
