'Orient 3' or 'East 3') and Vostok 4 (Восток-4, 'Orient 4' or 'East 4') were Soviet space program flights in August 1962, intended to determine the ability of the human body to function in conditions of weightlessness, test the ground control capability to launch and manage two separate, concurrent flights, and test the endurance of the ...

The Vostok-3 mission lasted 94 hours and Vostok-4 spent 71 hours in flight. The Soviet manned space flight record exceeded the America's only three-orbit mission by 60 orbits!

Vostok 3 set a new time record in space of 94 hours and traveled more than 1,600,000 miles (2,560,000 km) in Earth orbit. The final two missions in the Vostok series included the participation of the first woman cosmonaut. Vostok 5 lifted off on June 14, 1963, followed two days later by Vostok 6 carrying Valentina V. Tereshkova.

Vostok 3, the third spacecraft in the USSR's manned flight series, was piloted by cosmonaut Andriyan G. Nikolayev. The spacecraft consisted of a nearly spherical cabin covered with ablative material. There were three small portholes and external radio antennas.

2020年7月28日 · Vostok 3 and 4 was a daring double mission in which two separate spacecraft launched within a day of each other, on Aug. 11 and 12, 1962. Cosmonaut Andriyan Nikolayev rode on Vostok 3 and Pavel...

The Vostok 3KA was the spacecraft used for the first human spaceflights. They were launched from Baikonur Cosmodrome using Vostok 8K72K launch vehicles. The first flight of a Vostok 3KA occurred on March 9, 1961. The first flight with a crew—Vostok 1 carrying Yuri Gagarin—took place on April 12, 1961.

Vostok 3 studied man's ability to function under conditions of weightlessness; conducted scientific observations; furthered improvement of space ship systems, communications, guidance and landing. Immediately at orbital insertion of Vostok 4, the spacecraft were less than 5 km apart. Popovich made radio contact with Cosmonaut Nikolayev.

1961年3月25日，斯普特尼克10号 （Vostok-3KA 1）发射升空。带着小狗兹维奥兹多奇卡(小星星，Звёздочка)的返回舱成功着陆，并根据飞行计划将假人弹射出舱。

This was the first launch of what was to be the first double spaceflight. Vostok 4 would be launched the next day with Pavel R. Popovich aboard. The two craft passed within 6.5 km of each other. Vostok 3 and Vostok 4 landed within 15 minutes and 193 km of each other.

2020年8月11日 · Launch from the Baikonur Cosmodrome and landing 200 km southeast of Karaganda. This mission was a rendezvous flight with Vostok 4. Both spacecrafts came close to 6.5 km (visibility), although the Vostok capsules had no …
