On this day, 37 years ago, on August 29, 1988 (July 18, 1988 lunar calendar), a Soviet spacecraft successfully docked with the space station. Astronauts in the space station On August 29, 1988, cheers were deafening at the Baikonur launch site in the Soviet Union. Two days after the 49-meter-high spacecraft "Soyuz TM-6" sent the three astronauts into space, the Soyuz spacecraft and the "Peace" space station successfully docked over the Ural Mountains. People watched the spectacle on a large-screen TV at the Kaliningrad Space Center near Moscow. The three astronauts and the two residents of the "Peace" station warmly hugged and congratulated each other. Colonel Liakhov, who traveled in space for the third time, stayed in space this time for another eight days and investigated, and then transferred to "Soyuz-5" to return to Earth. The accompanying astronaut doctor Polyakov stayed at the "Peace" station to take care of Maganov and Titov, who had been working on the station since the end of 1987, until December 21, 1988. The three of them returned to land together. Manarov and Titov stayed on the space station for 366 days and nights, setting a record for the longest continuous flight in space and establishing a new feat in the history of human spaceflight. The achievements of the Soviet aerospace industry are amazing. On October 4, 1957, the Soviet Union launched the first artificial satellite, ushering in a new era of human conquest of the universe. A month later, the "Earth Companion-2" was sent into space with the first "passenger" puppy Laika. On September 12, 1959, the man-made spacecraft "Luna-2" landed on the moon for the first time. After the unmanned, ground-controlled lunar rover "Moonwalker-1" landed on the moon in November 1970, it walked on the lunar surface, observed, and sent data back to Earth. Five years later, the "Venus-9" and "Venus-10" probes landed on Venus one after another and sent back pictures of the surface of Venus. On April 19, 1971, Su launched the first orbital science station "Salyut-1". Four days later, the Soyuz-10 spacecraft carrying three astronauts successfully docked with it, setting a precedent for astronauts to stay in space for a long time and carry out various scientific research work. Astronauts are being tested on the Mir space station
