wrist and elbow joint of the ERA. Following the completion of the EVA's needed on the ERA, joint tests will be carried out, followed by multiple joint tests. Following the completion of these tests, the ERA will be relocated by grappling base points on the surface of the ISS and will be checked by being commanded to grapple and relocate the Portable Work Platform. The portable work platform launched with spare elbow joint on MRM-1 in 2010 can attach to the end of the ERA to allow cosmonauts to ride on the end of the arm during spacewalks. Upon completion the ERA will be placed in hibernation mode. The third stage will be the brakes run-in, thermal validation and imaging quality checks. This will have the brakes run-in so that they will function correctly to manipulate heavy payloads. As well thermal parameters will be monitored inside the ERA at different points. Finally the ERA cameras will be evaluated under different lighting conditions, and include the accuracy in proximity targeting by the end effector cameras as well as image quality. The final two stages of preparation of the ERA for full operation was checking its motion performance as well the procession of data on the ground. After completion of all five stages of the In-Orbit Validation to a satisfactory level, the ERA validation ended, and the ERA system was considered ready for operational use. Installation of outfitting equipment for Nauka Mission Preparation and Training Equipment Mission Preparation and Training Equipment (MPTE) are tools and facilities developed by National Aerospace Laboratory - NLR, used in the training of astronauts and operators, supporting maintenance, as well as aiding in missions. Three identical versions of the MPTE were installed at Rocket-Space Corporation Energia RSC/E, the Russian Mission Control Centre for the ISS, the Gagarin Cosmonaut Training Center (GCTC), as well as the European Space Research and Technology Centre (ESTEC). Both the arm and the MPTE had to be designed to be able to function and operate for a minimum of 10 years. In February and March 2006, the MPTE was delivered to several locations in Russia. Due to the delays in the launch, much of the hardware in the computer systems had surpassed its expected life span. As a result, it had become hard to maintain the computers in the MPTE as spare parts were becoming obsolete, and hard to find. As well the
