MIRNEWS.415 2 APRIL 1998

1st Spacewalk (EVA) 25th Main Expedition to MIR:

The EVA started (hatch opening between airlock Sh.S.O. and open space) =
15 minutes later than planned at 1335UTC. Budarin needed more time to =
open the locks of the hatch. Also considerably later than planned, the =
hatch closed behind Musabayev and Budarin at 2015UTC. So a duration of 6 =
hrs and 40 mins. There have been reports about a duration of 4 hrs: a =
mistake or April 1 prank.=20

All availble windows via the geostationary Altair-2 were used for =
radiotelephony. The information about the opening and closure of the =
hatch, taking place outside those windows, was reported by Musabayev =
afterwards.=20

The cosmonauts worked energeticly. Musabayev observed Budarin, =
instructed him what to do and warned him if he moved to fast or came too =
close to obstacles. He also now and then spoke with Andy Thomas to tell =
him how and from where to make photographs and video. Andy regularly =
reported temperatures inside MIR varying between 32 and 37 degrees =
Celsius. (Unclear what kind of temperatures)

Meanwhile the spacewalkers enjoyed the cool temperatures in their =
spacesuits.=20

For their transport M. and B. used the Strela crane. The package with =
the handrails which they had to install at the outside of the Spektr =
module had been placed outside MIR during one of the EVA's of Solovyov. =
They spoke about the 'Solovyov package'.=20

Unpacking, deploying and installing of these handrails lasted much =
longer than was expected and so there was no time left for the =
reinforcement of the damaged solar panel of Spektr by a beam. They also =
had to install 2 foot restraints for future work at Spektr. They =
succeeded in stalling just one of those restraints.=20

At approx. 1912UTC there was a gruesome event: Budarin called Musabayev, =
but he did not get a reaction. After a few minutes the voice of M. =
showed up again. He reported that he had switched off the power supply =
of his spacesuit by accident. Thus he lost all functions: cooling, =
communication, ventilation, destilation, etc. After restoring the =
powersupply he reported sequently the good functioning of his systems. =
(Whether this has been a April 1 prank or not, I do not know, but it =
made my flesh creep).=20

7 Minutes after the closure of the hatch which took place at 2015UTC the =
window for Altair-2 communications opened again. M. reported the time of =
the closure. From that moment on the long sequency of repressurizing, =
airseal checks and post EVA activities could be monitored. Towards the =
end of this window the cosmonauts were back in the Base Block and they =
managed to transmit some video images made by Andy Thomas during the =
EVA.=20

When the EVA and the repressurization were still going on, there were =
some VHF-windows. (As always during EVA's lower in the band, 143.618 mc) =
I could monitor these signals simultaneously with those via Altair-2. =
Due to the longer path of the signals via Altair-2 there was a very =
clear echo-effect.=20

And again there was the well-known interference (a kind of =
cross-modulation) from an airtraffic control centre. These signals also =
were relayed via Altair-2.=20

Sometimes this traffic bothered the cosmonauts.=20

When the cosmonauts came back in the PGO (Instrument and cargo =
compartment) from the PNO (Instrument and scientific compartment) the =
applaus from the people at TsUP could be heard in the background.

2nd EVA of the 25th Mainexpedition to MIR:

This EVA is scheduled for 6.04.1998 from 1155UTC for a duration of =
approx. 6hrs.=20

Main task: Splinting the damaged solar panel on the Spektr module.=20
