June 17, 1963 - The Russians reported Lieutenant Colonel Valery Bykovsky lost altitude today on his fourth day aloft in space. But his orbiting duet with blond Valentina Tereshkova continued and Tass said both retired for the night in their separate spaceships. There was no report of any change in the flight of the world’s first space woman. She had circles under her eyes in live television pictures, indicating some fatigue after more than a day in space. But she kept smiling brightly for the camera inside her craft, and radioed to earth from 100 miles out in space, “Tell Mama not to worry.”
