What did valentina terishkova discover?

Answer 1

She was the first woman in space, took pictures of the horizon : Although Tereshkova experienced nausea and physical discomfort for much of the flight,[4] she orbited the earth 48 times and spent almost three days in space. With a single flight, she logged more flight time than the combined times of all American astronauts who had flown before that date. Tereshkova also maintained a flight log and took photographs of the horizon, which were later used to identify aerosol layers within the atmosphere. That was from Wikipedia.

Valentina Tereshkova, a Soviet cosmonaut, became the first woman to travel into space on June 16, 1963. She piloted the Vostok 6 spacecraft and orbited the Earth 48 times during her mission.
