A:
Psychologist Kris Kelvin (Donatas Banionis) spends his last day on Earth reflecting on his life while walking by a lake near his childhood home where his elderly father still resides. Kelvin is about to embark on an interstellar journey to a space station orbiting the remote oceanic planet Solaris. After decades of study, the scientific mission at the space station has barely progressed. The crew is sending confusing messages. Kelvin is dispatched to evaluate the situation aboard the ship and determine whether the venture should continue.Henri Berton (Vladislav Dvorzhetsky), a former space pilot, visits Kelvin. They watch film footage of Berton's own testimony years before of seeing a four-meter-tall child on the ocean surface of Solaris while searching for two lost scientists.

Although he readily accepted the mission, it is a choice that weighs heavily upon Kelvin's conscience.Upon his arrival at Solaris Station,[10][11] a scientific research station hovering above the oceanic surface of the planet Solaris, none of the three remaining scientists bother to greet Kelvin, who finds the disarrayed space station dangerously neglected. He soon learns that his friend among the scientists, Dr. Gibarian (Sos Sargsyan), had killed himself. The two surviving crewmen are uncooperative and evasive. Kelvin...
