Launch from the Baikonur Cosmodrome and
landing 193 km southwest of Karaganda.
This was the first time that
more than one manned spacecraft were in orbit at the same time. The mission was
a
rendezvous flight with Vostok
3 at time. Both spacecrafts came close to 6.5 km (visibility), although
the
Vostok capsules had no maneuvering capability. They
quickly drifted apart. Pavel
Popovich had problems with his life support system, resulting
in the cabin temperature dropping to 10 degrees Centigrade with 35% humidity
conditions. But he still managed to conduct several experiments, and further
improve the space ship systems, communications (spaceship ground control and
from spaceship to spaceship), guidance and landing. His work included taking
color motion pictures of the terminator between night and day and of the cabin
interior.
Pavel
Popovich had been briefed to tell ground control that he was
'observing thunderstorms' if he felt the motion sickness that had plagued
German
Titov and would have needed to return. The problem was that
he actually saw real thunderstorms over the Gulf of Mexico, a fatal
misunderstanding that caused him to land one day earlier than
planned.
