The Skylab 4 crew was in orbit when Soyuz 13 launched back in December 1973. Is that the first time astronauts and cosmonauts were in orbit at the same time?Interestingly, the Soyuz 18 crew was onboard Salyut 4 when the Apollo-Soyuz (Soyuz 19) mission flew in 1975. Cosmonaut Pyotr Klimuk flew on both Soyuz 13 and Soyuz 18. |

The joint flights of Vostok 3 and Vostok 4 launched a day apart in August 1962. It was the first time that two manned spacecraft were in orbit at the same time. Vostok 4 landed about 7 minutes after Vostok 3 on August 15.The joint flights of Vostok 5 and Vostok 6 launched two days apart in June 1963. Vostok 6 landed a few hours before Vostok 5 on June 19. There are interesting accounts of the Vostok flights in Encyclopedia Astronautica, including some post-flight debriefng comments by the cosmonauts. |

Weren't there some early 70s Soyuz flights that did crew exchanges? |

January 1969... Soyuz 4 and Soyuz 5 swapped two crew members from Soyuz 5 to Soyuz 4. |

Vostok 4 landed about 7 minutes after Vostok 3 back in 1962. How far apart were the touchdowns? |

I quote from my diary for Wednesday 19th December, 1973: "Yesterday a historic event occurred. For the very first time Americans and Russians were in space at the same time. The mission of Soyuz 13, unlike Skylab 3, is obscure." |

Very roughly Vostok 3 landed about 100 kms south of Karaganda, Vostok 4 landed some 300 kms to the south east of this town. |

Thanks for that. I think all six cosmonauts ejected from their Vostok capsules prior to touchdown and landed using their own parachutes. |

A similar EVA and possible crew member swap were briefly considered for the Gemini 7 and Gemini 6A flights. Schirra and Stafford were all for the idea, but Borman was against it.It is mentioned in NASA SP-4203 on page 276. |

The STS-35 and Soyuz TM-11 were in orbit together in December 1990. ------------------

Had Soyuz-1 not encountered problems on orbit which required what subsequently turned out to be a fatal return to earth, Soyuz 2 was planned to launch the following day with cosmonauts Bykovsky, Khrunov and Yeliseyev aboard. After linking up, Khrunov and Yeliseyev would have transferred to Soyuz-1 for landing along with commander Komarov. In which case the Soviet Union would almost certainly have lost three cosmonauts due to the faulty parachute system on that spacecraft, which may even have been fatally replicated in Bykovsky's Soyuz-2. The loss of Komarov was bad enough, but imagine the ramifications had they lost four cosmonauts aboard two spacecraft? |

A pretty ambitious flight plan for the first manned Soyuz flight. Those early Soyuz missions had some major in-flight problems.Khrunov and Yeliseyev were the two cosmonauts who completed the Soyuz 5 to Soyuz 4 EVA transfer mentioned earlier. The Soyuz T-4 cosmonauts were onboard Salyut 6 when STS-1 launched in 1981. By my rough count, only 19 of 135 shuttle flights launched when there were no cosmonauts in orbit. |
