Russian Boom for Solar Arrays

The Russian Boom for Solar Arrays is a telescoping extension which connects the Solar Arrays to the Radiators and the Base.  The boom also holds the Autonomous Thruster Facility (not shown), which will maintain the correct orientation for the Space Station in orbit.  The thruster facility will be fully fueled when it is launched.  When all its fuel has been used up a replacement thruster will be sent from the Earth and the unit will be changed.

Also on the boom will be the European Robotic Arm manipulator, and  a transport trolley to carry the arm up and down the Russian Boom.
