Where we always second guess!
Soviet cosmonaut and aviator Svetlana Yevgenyevna Savitskaya, on August 19, 1982, became the second woman to go into space. Her mission, which was a flight to the Salyut 7 space station and back, lasted about 8 days. As part of a three-person crew, she flew to the station on the Soyuz T-7, and back from the station on the Soyuz T-5.
Savitskaya’s second spaceflight was her most well-known. During that flight, July 25, 1984, she became the first woman to conduct an EVA (extra-vehicular-activity, that is, she did a spacewalk). While floating outside of her vehicle, she conducted welding experiments where he actually cut and welded materials in space.
