MIRNEWS.393                                3 NOVEMBER 1997
4th Spacewalk (EVA) crew 24th Main Expedition to MIR. 
The EVA lasted from 03.32.30UTC (opening hatch) until 0937UTC (closing hatch) 
, so duration 6 hrs 4 mins.  The EVA bega n later due to a failure in a 
telemetry unit of Solovyov's spacesuit.    After the opening of the hatch  
Vinogradov lau nched the minisputnik PS-2 (or: Sputnik 40 or RS-17). Then the 
crew dismantled the MSB-4, the old solarpanel on Kvant-1
 (module-E), which originally was installed on Kristall.  They parked the 
solarpanel at the outside of the Base Block. 
The clamps between the segments of the solarpanel had to be opened 
electrically from a keyboard inside MIR . Wolf who g ot instructions from 
Solovyov took care of this task. He also made video- and photo-images of his 
colleagues.  
Further they installed a cap at the outside of the Base Block to close an 
outlet for a new Vozdukh CO2 scrubber. Now th is outlet has been sealed off 
the crew can install a valve on the inside of the Base Block where a new 
Vozdukh will be installed. Through that valve the Vozdukh can blow  CO2 and 
water vapour into open space. This valve will be installed on 4.11.1997. If 
the crew succeed they can remove the cap from the outersurface during the 
next EVA on 6.11.1997. 
 
The Altair-2 satellite was scarcely used possibly due to the fact that the 
area in which the cosmonauts had to work was
 very close to the ONA, the Antenna for the Antares transmitter. Altair-2 was 
in use before and during the return of th e cosmonauts in the airlock of 
Module-D. Simultanuously they communicated via the VHF channel on 143.618mc.
PS-2 (Sputnik 40 or RS-17): During the VHF windows of MIR the transmitters of 
this minisputnik could be monitored on 14 5.820 mc. The signals  are not very 
strong.  The use of the reception mode USB helps a lot.
