Underwater Training for Cosmonauts: Preparing for the European Robotic Arm Era

The video discusses the preparation of cosmonauts for installing the European robotic arm, ERA, on the ISS. The training takes place underwater to simulate weightlessness, allowing cosmonauts to practice assembling the arm. Despite challenges like limited vision and tool handling, the training is successful. ERA, initially planned for launch in 2001, is set to fly in 2007, enhancing the ISS's capabilities. The Yuri Gagarin Hydrolab plays a crucial role in training, and procedures are refined to prevent issues during the actual mission. The Space Shuttle Discovery is also set to resume ISS services.
