MIRNEWS.364 27 JUNE 1997
Progress-M34: The Russians abandoned the plan to finish the existence
of this freighter today. Pr-M34 is still
needed for Telemetry analyses, necessary for the investigations
on the cause of the 'mini-cat astrophe. For the time being it
is extremely difficult to get a reliable picture of that what happened
due to the
huge amount of versions and rumours about the failed docking attempt.
When Pr-M34 will enter the earth's atmo sphere and decay has been not
decided, it might take place on 28 or 29.07.97.
Inquiries: An extensive commission under the chairmanschip of the Head
of the RKA (Russian Space Agency),
Yuriy Koptev, discussed the situation on 26.07.97 and decided to
delegate the investigations to one or more w orking groups. These
specialists will pay extensive attention to the Telemetry from Pr-M34
after the undocking unti l the collision. Already before the session of
the commission Koptev gave a statement in which he emphasized
that the operations with MIR will not be interrupted, that the
crew will not be evacuated and that Russia
will perform her obligations in the framework of the
international cooperation. (How far political int entions will conflict
with technical imperfections and even impossibilities certainly will turn
out in due cour se.)
Intentions and options known up to now (27.06.1997 1200UTC): A lot of
press-releases speak about the necessity
to make a spacewalk (EVA) for the inspection and eventual repair of the
little gap or crack in the hull of M odule Spektr. Such an EVA will
certainly be executed, but this will take place not before the
arrival of the
next cargoship Progress-M35. The first EVA will be a so called
'internal EVA' using the transition section (P.Kh.O.) as an airlock via
which the cosmonauts can enter the Spektr.
Module Spektr: For a long time this module was the 'base and home' of
the American astronauts. In this module Fo ale disposed about a lot of
equimpent and experiments. The crew has to determine what still is
available and can be saved and what is lost. For the time being a lot of
experiments cannot be executed and in fact the experi mental program for
this expedition is almost fully suspended. One of the 4 solarpanels of
Spektr has been severely d amaged, possibly beyond repair. The other 3
might be able to deliver power, but due the disconnection of cables ,
some of those cables had even to be cut in two, they are out of order.
The damaged one and one of the other 3
are badly needed for powersupply for the whole complex. The event caused
a powerreduction of appr. 50% . Before
I spoke about a little gap or crack and not as generally is done in
publications about this damage, about
a gap, or even big hole. If it would be a real gap the crew would be
dead. Depressurization would have been a matte r of seconds not only or the
Spektr but also for the whole complex. This depressurization was in fact
a process which passed off slowly. The crew felt the decrease of
the pressure in their ears and they had still enough
time to close one of the hatches to Spektr and -possibly we will hear
about this later- do a lot of things before
closing that hatch.
Situation on board of MIR : A summary about the developments after the
collision as derived from the enormous amount of radiotraffic will be
published in NEWS.365.
