'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 and Vostok 4 were both launched on Aug. 11, 1962, and orbited in sight of each other. 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.

2017年8月15日 · Major Andrian Nikolaev, 33 and a Chuvash Russian, kicked off the mission the early morning (our time) of August 11. His Vostok 3 ("Falcon") was in space for a full day before his spaecebound comrade, 32-year old Ukrainian Lt. Col. Pavel Popovich blasted off in Vostok 4 ("Golden Eagle"), morning of August 12.

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...

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.

Vostok 4 was a mission in the Soviet space program. It was launched in August 1962, a day after Vostok 3 with cosmonaut Pavel Popovich on board—the first time that more than one crewed spacecraft were in orbit at the same time. The two Vostok capsules came within 6.5 km of one another and ship-to-ship radio contact was established.

Vostok 3 and Vostok 4 landed within 15 minutes and 193 km of each other. Nikolayev unstrapped himself and floated free in his small capsule, the first person to do so. He did not suffer any space sickness during his flight.

The NASA elements for Vostok-3 match radio observations quite well, but the element set at launch for Vostok-4 is the same as that for Vostok-3 that same morning, which is not correct. The two spacecraft were injected into orbits with different orbital periods.

2013年10月17日 · In February of 1962, the United States put John Glenn into orbit. This prompted Soviet leadership to suddenly asked Chief Designer Korolev to launch the next space spectacular promptly. To make this mission truly spectacular the Soviets decided to launch a group flight of two Vostoks lasting up to four days in orbit.
