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.
“On behalf of the family, I’m confirming the very sad news about the death of Gen. Miroslaw Hermaszewski,” Czarnecki tweeted, calling him a “great pilot, good husband and father, and much beloved grandfather.”
Hermaszewski became a national hero thanks to his trip to space. For nine days in June and July of 1978, Hermaszewski and Soviet cosmonaut Pyotr Klimuk circled the Earth in the Soyuz 30 spaceship that docked at the Salyut 6 orbital space station. They went around the globe 126 times.
In an 2018 interview with the Polish newspaper Rzeczpospolita, Hermaszewski said his biggest fear during the flight was that their spacecraft would be struck by a meteor. His and Klimuk’s senses were sharpened, catching even the smallest sound, he said.
Hermaszewski traveled into space as part of the Soviet Union’s Intercosmos program, which offered an opportunity to explore space for countries within the then-Eastern Bloc, under Moscow’s domination or which had ties with the Soviets.
The first person to blast off as part of the program was Vladimir Remek of then-Czechoslovakia, in March 1978. Hermaszewski followed, while Sigmund Jahn of then-East Germany was the third to fly that year. They all trained at the Star City space flight preparation facility outside Moscow.
Among other countries that contributed cosmonauts were Hungary, Bulgaria, Cuba, Vietnam, Mongolia, Romania, Syria, Afghanistan, and India. France later took part in the program, sending Jean-Loup Chretien in 1982.
