ANOTHER SOVIET SPACE SPECTACULAR,  THE JOINT FLIGHT OF VOSTOK-5 (see
newspaper article) FOLLOWED TWO DAYS LATER BY VOSTOK-6 CARRYING
VALENTINA TERESHKOVA, THE FIRST WOMAN IN SPACE.
On June 14, 1963 the Soviet Union launched Vostok-5, piloted by Lt. Col.
Valery F. Bykovsky. - see newspaper article to the right--->>>>>>>>>>>>>>>>
SEE ABOVE STAMP- Following about a day later, on June
16,1963, Lt. Valentina Tereshkova rode Vostok-6 into orbit
as  the first spacewoman.  On the first orbit, Vostok-6 came
within 5km of Vostok-5 and established radio contact.  At
the time, this was impressive shooting for Russian
rocketry.  Both Cosmonauts landed safely on June 19th.  
NOTE-  A GREAT job by the Russian Launch Team, after
firing Vostok-5 into orbit and then following with the rapid
launch of Vostok-6.  This demonstrates a fast turn around
time for Baikonur Pad#1 and a professional support crew.

Early Russian Cosmonauts were trained to communicate in Morse code as a backup
to their AM voice mode of operation.  The Russian spacecraft from that era relied
heavily on shortwave radio which is dependent on favorable atmospheric
conditions.  When shortwave radio conditions were poor, the cosmonauts had to
abandon their AM voice mode and switch to Morse code which is more readable
through static and weak signal conditions.  Above, in a training session,  Cosmonaut
Valentina Tereshkova listens to code being sent by Cosmonaut Yuri Gagarin.
