MIRNEWS.306 25 MAY 1996 3d Spacewalk (EVA) crew 21ste Main Expedition MIR: The cosmonauts Onufriyenko and Usachov made this EVA between 24.05 at 2047UTC and 25.05 at 0230UTC. This EVA lasted somewhat longer than planned, but all went well. The cosmonauts installed the new solarpanel on the outersurface of Kvant-1, connected the contacts and attended the deployment of that panel. This was also a good performan ce. During the last phase of the EVA radiotraffic went via Altair-1 (Cosmos-2054) and the known VHF-frequencies. After returning inside MIR the cosmonauts expressed their satisfaction about the good cooperation with TsUP during this work and also about the very good construction of the new solarpanel. 4th EVA: This EVA is on schedule for 30.05.1996 between 1900- 2100UTC. Main task will be the transfer of the MOMS (optoelectronic stereoscanner) to the outersurface of the Priroda module and the installation of this device over there. The MOMS has been delivered to MIR as a part of the cargo of the Priroda. Apart from this work they will also have to accomplish some minor tasks. Chris v.d. Berg, NL-9165/A-UK3202.
