Like Vostoks 3 and 4, Vostok 5 and 6 were joint missions in the Soviet space program, and like the previous pair, came close to one another in orbit and established a radio link.
Cosmonaut Valery Bykovsky was originally intended to stay in orbit for eight days, but the mission details changed many times due to elevated levels of solar flare activity at the time and he was eventually ordered back after only five days.
A problem with the spacecraft's waste collection system is reported to have made conditions "unpleasant" in the capsule. The only other difficulty encountered was that, like on Vostoks 1 and 2, the re-entry module failed to separate cleanly from the service module when it was time for Bykovsky to come home.
The re-entry capsule is now on display at the Tsiolkovsky Museum in Kaluga.
