Part of the mission's goal was to track the impact of being in space on the human body. Scott Kelly has an identical twin, Mark, who was studied together with Scott to track the impact.
Star City is a training training center for cosmonauts in Russia, where Kelly went through training and monitoring together with Russian cosmonauts before the mission.
