Dr. Kris Kelvin arrives on Solaris Station],[5] a space station orbiting the ocean planet of Solaris. The scientists there have been studying the planet and its ocean for many decades. Shortly before Kelvin's arrival, the crew exposed the ocean to a high-energy gamma-ray bombardment. The ocean's response tests the scientists' minds by confronting them with their most painful thoughts and memories. The ocean does this by materializing physical human simulacra. Kelvin confronts memories of his dead lover and guilt about her suicide. The torments of the other researchers are only suggested but seem even worse than Kelvin’s personal ordeal. The ocean’s intelligence expresses physical phenomena in ways difficult for their limited science to explain, deeply upsetting the scientists. The alien mind of Solaris appears to differ so much from the human mind that communication doesn't seem possible.
