Valentina Tereshkova became the first woman to travel in space when Vostok 6 launched on June 16, 1963. Her flight belonged to the Soviet Vostok program and occurred two days after Valery Bykovsky launched aboard Vostok 5.
Tereshkova had worked in a textile factory and developed substantial parachuting experience before cosmonaut selection. That experience mattered because Vostok crews did not land inside the capsule: the cosmonaut ejected during descent and completed the final landing by parachute.
The Soviet Union selected a small group of women for cosmonaut training in 1962. NASA historical material notes that political and propaganda considerations were part of the selection environment as the Soviet Union sought another highly visible space first.
Vostok 6 used the call sign Chaika, or Seagull. Tereshkova completed 48 orbits over nearly three days, communicating by radio and conducting observations during the flight.
Vostok 5 and Vostok 6 approached within a few miles during their separate orbital missions, but they did not dock. Any description of a joint mission should therefore preserve the distinction between coordinated simultaneous flights and physical rendezvous or docking.
Tereshkova returned June 19 and completed a parachute landing after ejection from the descent module. The procedure was normal for Vostok rather than an emergency.
She never flew in space again. The next woman in space, Svetlana Savitskaya, did not fly until 1982, emphasizing how little the symbolic first immediately changed crew selection patterns.
For TransitSatellite, the mission should be shown as an orbital transportation story with launch, repeated Earth orbits, reentry and parachute landing rather than as an aviation route between cities.
