WARSAW, Poland—Poland’s only cosmonaut, Gen. Miroslaw Hermaszewski, who circled the Earth in a Soviet spacecraft in 1978, has died. He was 81.
The retired air force pilot’s death on Monday was announced via Twitter by his son-in-law, European Parliament member Ryszard Czarnecki. He later told Polish media outlets that Hermaszewski died at a hospital in Warsaw of complications from a surgery he had undergone in the morning.
