Vostok 6 was the first human spaceflight mission to carry a woman -- cosmonaut Valentina Tereshkova -- into space. This was to some degree a publicity exercise on the part of the Soviet government. Data was collected on the female body's reaction to spaceflight. Like other cosmonauts on Vostok missions, she maintained a flight log, took photographs, and manually oriented the spacecraft. Her photographs of the horizon from space were later used to identify aerosol layers within the atmosphere. The mission, a joint flight with Vostok 5, was originally conceived as being a joint mission with two Vostoks each carrying a female cosmonaut, but this changed as the Vostok program experienced cutbacks as a precursor to the retooling of the program into the Voskhod program. Vostok 6 was the last flight of a Vostok 3KA spacecraft.
According to reports and rumors over the years, Tereshkova was reported to have experienced several physical problems during her flight, including space sickness and significant menstruation[citations needed]. Some reports also claim that at one point in the flight she had become hysterical and began crying uncontrollably until verbally scolded back to rationality by Sergei Korolev over the radio link[citations needed]. However, despite her problems, records and evidence both from before and after the fall of the Soviet Union contend that she completed the flight program as specified.
It was revealed in 2004 that an error in the control program made the spaceship ascend from orbit instead of descending. Tereshkova noticed the fault on the first day of the flight and reported it to Sergey Korolev. The mistake was promptly repaired – Tereshkova entered the data that she got from the Earth into the descending program and landed safely.
By request of Soviet spaceship designer Sergey Korolev, Tereshkova kept the problem secret for dozens of years. “I kept silent, but Evgeny Vasilievich decided to make it public. So, I can easily talk about it now,”
The landing site was the Pavinskiy Collective Farm west of Bayevo in the Altai Region. After parachuting from the capsule, Tereshkova barely missed the lake because of the violent wind. After the landing, the wind was blowing off her parachute, and Tereshkova received a large nose bruise before she managed to free herself from it.
The re-entry capsule is now on display at the RKK Energia Museum in Korolyov (near Moscow).
This was the final Vostok flight.
