Which person flew into space first, Ivan Bella or Sigmund Jähn?
Ivan Bella Ivan Bella (born 25 May 1964 in Brezno, Czechoslovakia (now Slovakia)) is a Slovak Air Force officer who became the first Slovak citizen to fly in space. He participated in an eight-day joint Russian-French-Slovak mission to the Mir space station in 1999.
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.
