Which person flew into space first, Ivan Bella or Sigmund Jähn?
Sigmund Jähn Sigmund Werner Paul Jähn (born 13 February 1937) is a German cosmonaut and pilot, who in 1978 became the first East German (and German native) to fly in space as part of the Soviet Union's Interkosmos programme.
Yuri Kondratyuk Yuriy Vasilievich Kondratyuk (real name Aleksandr Ignatyevich Shargei, Ukrainian: Олександр Гнатович Шаргей , "Oleksandr Hnatovych Sharhei") (June 21, 1897 – February 1942) was a Soviet engineer and mathematician. He was a pioneer of astronautics and spaceflight, a theoretician and a visionary who, in the early 20th century, developed the first known lunar orbit rendezvous (LOR), a key concept for landing and return spaceflight from Earth to the Moon. The LOR was later used for the plotting of the first actual human spaceflight to the Moon. Many other aspects of spaceflight and space exploration are covered in his works.
