16 Jan : Humans transferred in space

Do you remember the film ‘Martian’. It has a reel life story of real life incident. Today in 1969, Soviet spacecraft Soyuz 4 and Soyuz 5 performed the first-ever docking of manned spacecraft in orbit. Soviet cosmonauts Aleksei Yeliseyev and Yevgeny Khrunov transferred from Soyuz 5 to Soyuz 4, which were docked together. It was the first-ever transfer of crew from one space vehicle to another, and the only time such a transfer was accomplished with a space walk.

They remained docked for four and a half hours – three orbits of the Earth. During that time, two cosmonauts ‘space walked’ from Soyuz 4 to Soyuz 5, becoming the first spacefarers to return to Earth in a different spacecraft from the one in which they went into space. It was not until 1978 that this was repeated – when the Soyuz 27 crew returned to Earth from Salyut 6 aboard Soyuz 26.

आज 1969 में पहली बार अंतरिक्ष में दो स्पेसक्राफ्ट के क्रू मेंबर्स ने स्पेसक्राफ्ट की अदला-बदली की। स्पेस में चलते हुए एक स्पेसक्राफ्ट का क्रू मेंबर दूसरे स्पेसक्राफ्ट में गया और दूसरे स्पेसक्राफ्ट का क्रू मेंबर पहले स्पेसक्राफ्ट में गया। ये स्सोवियत पेसक्राफ्ट थे Soyuz 4 और Soyuz 5। आसमान में चलते हुए एक स्पेसक्राफ्ट से दूसरे स्पेसक्राफ्ट में पहुंचना कितना मुश्किल और खतरनाक होता है इसका अंदाज़ा आप ऊपर लगे वीडियो को देखकर लगा सकते हैं।
