The Russian Soyuz MS spacecraft that carries crews today, Rogozin said, is the “world’s most reliable spacecraft” with 173 successful flights, and three aborts in 1975, 1983 and 2018 that allowed the crews to eject safely. The Soyuz rocket that carries the spacecraft overall has more than 1,900 successful launches, he added. “The U.S. engineers have yet to earn this reputation. I sincerely wish them luck,” he said.
