Launch from the Baikonur Cosmodrome; 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 maneuvering
capability. They quickly drifted apart. Vostok 3 also conducted several
scientific observations and further improvement of the space ship systems,
communications (spaceship ground control and spaceship to spaceship), guidance
and landing. There were no problems with his spacesuit, but there was only a
minor problem with the Tral telemetry system.

was launched the next day aboard
. Data on the two spacecraft's
orbital parameters that were released periodically by Soviet news agency TASS
seemed to indicate a change in Vostok 3's orbital trajectory within ten hours
of Vostok 4
's launch, leading to
speculation that the former spacecraft modified its orbit to bring it closer to
that of the latter. The Vostok spacecraft is not believed to have had the
ability to modify its orbit. Plans were for the spacecraft to approach to 5 km
(3.1 mi), but the closest distance achieved was 6.5 km (4.0 mi). At the start
of Vostok 3's thirty-third orbit this distance had diverged to 850 km (530 mi),
and to 2,850 km (1,770 mi) at the start of the sixty-fourth.
made contact with one another via shortwave radio
soon after their spacecraft approached one another; they would maintain regular
ship-to-ship communications over the course of their mission in addition to
their contact with the ground. Andriyan

spent time out of their seats each day, conducting a
series of tests to determine their ability to maneuver and work in conditions
of weightlessness. Each test was said to last "about one hour." The physical
and mental state of the cosmonauts were monitored: biometric sensors relayed
the cosmonauts vital statistics to the ground; the cosmonauts' behavior and
coordination was observed via a cabin-mounted video camera; and the cosmonauts'
ability to perform various operations in coordination with ground controllers
was considered. The cosmonauts' speech was monitored both by controllers on the
ground and one another. The results of the tests were deemed positive, evidence
of the ability of humans to function and work over longer periods in
A final "first" for Vostok 3 was Andriyan
's taking of colour movie footage of the Earth from
orbit and from the cabin interior.
The reentry was the same procedure
as in the other Vostok missions.
