Launch from the Baikonur Cosmodrome; landing
620 km northeast of Karaganda or 200 km west of Barnaul The spacecraft carried
the first female cosmonaut.
The flight objectives included: Comparative
analysis of the effect of various spaceflight factors on the male and female
organisms; medico biological research; further elaboration and improvement of
spaceship systems under conditions of joint flight.
This mission was a
rendezvous flight with Vostok 5
km distance) at time. There were directly communication between both capsules
during the closest approach.
During the mission Valentina
suffered from space sickness and did not reply
during several communications sessions. It is unknown until today, if this was
due to an equipment failure or, that she had been paralysed with fear. It was
also planned, that she took manual control of the spacecraft, but that was
hat also problems (pain) with her right shin. She
did not eat enough during their flight, because the bread was too dry.
On the other side, she filmed cities, forrests, and rivers, but didn't complete
the biological experiment - she couldn't reach the equipment. Star observations
were also performed and she took two photometric measurements, even writing was
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
, 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.
Many errors occurred
in the entire landing sequences, including actions of the
recovery forces. Both spacecraft landed two
degrees of latitude north of the aim point. It was calculated that this could
have occurred by duplicate landing commands having been sent, but such a
failure could not be duplicated in post flight tests of ground
It was revealed in 2004 that an error in the control program
made the spaceship ascend from orbit instead of descending. Valentina
noticed the fault on the first day of the flight
and reported it to Sergei Korolev. The mistake was promptly repaired. Valentina
entered the data that she got from the Earth into
the descent program and landed safely.
