MIRNEWS.380 25 AUGUST 1997
Internal Spacewalk (IVA): accomplished on 22.08.97 from 1114-1430UTC. Some
minor technical irregularities caused a de lay of more than 2 hours. The
crew worked according to a checklist (cyclogram). This checklist contained
hundreds of items. The activities according to this checklist continued when
the MIR was out of range of tracking stations or the g eostationary Altair-2.
This time Altair-2 was in use for phone conversations only. Altair-2 was
active long before the IVA began, for instance during orbit 65734 from
0640-0732UTC. The crew donned their spacesuits and Foale went on b oard
Soyuz-TM26.
According to plan the preparations for the IVA had to be concluded and the
hatch to Spektr had to be opened during the window in orb. 65735,
0826-0910UTC. A valve (KVD) between the P.Kh.O. and one of the modules
(possibly module-T) coul d not be closed which caused a delay of about 1
hour.
In orbit 65736 (0958-1043UTC) all went well and at 1015UTC the pressure in
P.Kh.O. (serving as airlock for this IVA) was 50 mm. At that moment the
pressure in the space suit of Vinogradov decreased due to a leak in his left
glove. The
crew immediately repressurized the P.Kh.O. They did this before the end of
the window and Vinogradov could put on a s pare glove. At 1114UTC when the
MIR was out of range the hatch to Spektr had been opened.
Orbit 65737, 1135-1216UTC.: IVA going on. All went well. Solovyov had
joined Vinogradov inside the module. Vinogradov
had already connected cables at the connectors of the new hatch and except
for a single cable he did not met proble ms. During this window and the
following one (orb. 65738/39, 1310-1400UTC) V. and S. inspected the
interior of Spektr
and retrieved a lot of thusfar not specified items from there. During these
activities they consulted Foale. Vinograd ov reported that he saw ventilators
and pumps which were still working. He and S. did not find traces of
exploded mo nitors or test-tubes. They did not succeed in finding places
where the hull of Spektr had been penetrated. At last V.
and S. left the Spektr to prepare the closure of the hatch. Foale ,
keeping a log book, reported that the hatch h ad been closed at 1430UTC.
After repressurizing the P.Kh.O. in orb. 65740 (1448-1528UTC), Foale joined
his colleagues over there. In a short state ment he expressed his admiration
for the achievements of his crewmates and those on Earth who had been
working on thi s operation.
