The prelaunch processing of the Progress-MS-13 cargo transport spacecraft is in progress at the Baikonur Cosmodrome. Specialists of RSC Energia and Space Center Yuzhny completed the check of the spacecraft solar arrays (SA) with control illumination.

Work on the parameter control of solar arrays envisages opening of the stand sites where the spacecraft is installed, installation of technological tables-templates, removal of protection panels from solar arrays and their deployment, after which the solar array illumination and operation control are provided with special illuminators. Upon completion of work the solar arrays were folded and covered with protection panels anew.
