On July 25, 1984, Soviet cosmonaut Svetlana Savitskaya made history by becoming the first woman to perform a spacewalk. This groundbreaking event took place during the Soyuz T-12 mission to the Salyut 7 space station. Savitskaya, along with her crewmates Vladimir Dzhanibekov and Igor Volk, launched from the Baikonur Cosmodrome in Kazakhstan. Once they docked with the space station, Savitskaya and Dzhanibekov began their preparations for the spacewalk. On July 25, the two cosmonauts donned their bulky Orlan spacesuits and ventured outside the space station. During the 3-hour and 35-minute spacewalk, Savitskaya and Dzhanibekov conducted welding experiments, testing out a new type of electron beam hand tool designed for cutting and welding materials in space. Savitskaya's historic spacewalk was a major milestone for women in space exploration. It came 19 years after the first-ever spacewalk performed by Soviet cosmonaut Alexei Leonov in 1965, and 20 years after Valentina Tereshkova became the first woman in space in 1963. Imagine the excitement and nervousness Savitskaya must have felt as she stepped out of the airlock and into the vast expanse of space. The incredible views of Earth below and the twinkling stars above must have been breathtaking. As she worked alongside Dzhanibekov, wielding the innovative welding tool, she knew that her actions were not only advancing space technology but also breaking down barriers for women in the space program. Savitskaya's achievement paved the way for future female spacewalkers, including NASA astronauts Kathryn Sullivan (1984) and Peggy Whitson, who holds the record for the most spacewalks by a woman (10 spacewalks totaling 60 hours and 21 minutes). Today, we celebrate Svetlana Savitskaya's bravery, determination, and the historic leap she made for women in space on July 25, 1984.
