Soyuz 9 (Russian: Союз 9, Union 9) was a June, 1970, Soviet crewed space flight. The two-man crew of Andriyan Nikolayev and Vitaly Sevastyanov broke the five-year-old space endurance record held by Gemini 7, with their nearly 18-day flight.

联盟号飞船是前苏联继 东方号载人飞船 和 上升号载人飞船 后自研的第三款载人飞船，是世界上服役时间最长、发射频率最高，同时可靠性最好的载人飞船，其原目的是作为苏联载人登月计划中的往返工具，由于苏联后来取消了登月计划，联盟号飞船的活动范围就此被限制于地球轨道。 1991年红旗落地后，联盟号技术等转由俄罗斯航天局掌握，主要负责对 和平号空间站 与 国际空间站 的人员运输、物资补给。 2011年美国航天飞机全线退役后，直至2020年美国的 载人龙 飞 …

2020年3月28日 · Soyuz 9 performed the first night launch in the era of human spaceflights. The crew performed photographical and visual Earth observation, several astrophysical, physiological experiments and technical studies.

The Soyuz-9 spacecraft lifted off from Pad 31 in Tyuratam on June 1, 1970, at 22:00 Moscow Time, with commander Andriyan Nikolaev, and flight engineer Vitaly Sevastyanov onboard. Nine minutes after the liftoff, the spacecraft successfully entered a 219.0 by 206.2-kilometer orbit with an inclination 51.7 degrees toward the Equator.

Head-over-heels rotation of Soyuz to conserve fuel and lack of exercise resulted in terrible condition of astronauts on return. The Soviets almost reconsidered their space station plans as a result. AKA: Sokol (Falcon). Launched: 1970-06-01. Returned: 1970-06-19. Number crew: 2 . Duration: 17.71 days. Manned flight endurance test.

Soyuz (Russian: Союз, IPA:, lit. 'Union') is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau (now Energia).

1970年6月1日 · Soyuz 9 carried cosmonauts Andrian Nikolayev & Vitali Sevastyanov to orbit. The mission lasted 17 days, 16 hours & 58 minutes completing 288 orbits around Earth. They broke the endurance record held by Gemini 7 for 5 years. This was the first crewed space launch that lifted off at night.

Soyuz 9 was piloted by veteran cosmonaut A. Nikolayev, commander, and V. Sevastyanov, flight engineer. The flight tested, for a longer period of time than any other, the capacity of the hardware and the human crew.
