• D. Voskhod spacecraft
  The Voskhod spacecraft was a Soviet crewed space capsule that succeeded Vostok and enabled milestones such as the first multi-person crewed mission and the first spacewalk during the early space race.
• E. Falcon 1 rocket
  Falcon 1 rocket is a small, privately developed orbital launch vehicle created by SpaceX that became the first privately built liquid-fueled rocket to reach orbit.
