War In Ukraine Brings Tension To Russian, U.S. Space Programs

Mark Vandehei spent nearly a year on the ISS, setting a record for the longest single spaceflight by an American. His mission aimed to study microgravity's effects on the human body. During his stay, Russia invaded Ukraine, raising questions about US-Russia relations in space. Speculation arose when Russian crew members wore yellow and blue suits, thought to show solidarity with Ukraine, but Vandehei clarified it was unintentional. A Twitter spat between Scott Kelly and Russia's space program head did not affect Vandehei's confidence in international cooperation. He has since returned to Earth, adjusting to gravity with some discomfort.
