Key answer first
The first female spacewalk was performed by Soviet cosmonaut Svetlana Savitskaya on July 25, 1984, during the Soyuz T-12 mission to the Salyut 7 space station. She stepped outside with mission commander Vladimir Dzhanibekov to test tools, techniques, and a specialized spacesuit, marking the first time a woman had left a spacecraft in orbit. The walk lasted 3 hours and 35 minutes and helped prove that women could conduct complex extravehicular activities in support of future long-duration missions and space station assembly.
Why this milestone still matters
The first woman to walk in space reshaped how agencies think about crew selection, training, and EVA planning. It demonstrated that EVA capability was not limited by gender, informed spacesuit design, and expanded the pool of candidates for long-duration missions on stations that evolved into today’s International Space Station. Savitskaya’s flight also highlighted the importance of having crew members with diverse skills perform tasks outside the spacecraft, influencing protocols and training for both Russian and U.S. programs.
Historic context: women in space before the first EVA
By the mid-1980s, women had already flown in orbit, but no had yet exited a spacecraft in open space. Earlier missions had proved that women could function safely in weightlessness and operate complex systems inside a spacecraft. The next logical step for many spacefaring nations was to validate that women could also perform the more physically demanding work of an EVA, including tool use, tethering, and managing umbilicals in a vacuum environment.
Salyut 7 and the Soviet program’s EVA capabilities
At the time, the Salyut 7 station was regularly crewed, and Soviet spacewalkers were routinely tasked with installing sensors, inspecting hulls, and testing construction techniques. The availability of a dedicated airlock and an experienced cadre of EVA-trained cosmonauts created the conditions for including a female crew member in an EVA. The Soyuz T-12 mission was planned as a visiting expedition to Salyut 7 with the explicit goal of testing a female cosmonaut’s performance during an EVA.
The visiting crew that flew Soyuz T-12
Soyuz T-12 carried a visiting expedition to Salyut 7 that included Vladimir Dzhanibekov, commander and an experienced spacewalker; Svetlana Savitskaya, research cosmonaut and the first woman to perform an EVA; and Igor Volk, a test cosmonaut serving as flight engineer. Their combined experience in EVA, spacecraft docking, and scientific work supported a focused set of objectives aimed at proving women could conduct meaningful tasks outside the station.
Mission and EVA details
On July 25, 1984, Savitskaya and Dzhanibekov departed Salyut 7 through the station’s airlock, tethered to handrails and equipped with cameras and tools to test techniques that would support future construction and repair work. Activities focused on transferring materials, using cutting and welding tools, and evaluating the stability of a crew member in open space while wearing a spacesuit designed for women. The EVA was carefully choreographed, with ground control monitoring suit telemetry, tether security, and crew fatigue to refine procedures.
Hardware and tools used on the first female EVA
The cosmonauts used standard Soviet EVA tools adapted for the mission, including handheld cameras, a welding apparatus, and foot restraints to anchor themselves while working. An important goal was testing a specialized spacesuit intended for women, assessing mobility at the joints, comfort during sustained work, and the behavior of the life-support backpack in microgravity. Data from this walk informed later spacesuit iterations and contributed to the development of modular tools that could serve both male and female crew members.

Operational lessons and best practices highlighted by the EVA
- Pre-EVA training should include gender-neutral task design so that suits, tools, and restraints work for any crew member.
- Telemetry and real-time monitoring of suit systems are essential when an EVA represents a new demographic profile.
- Planning should account for variation in reach, strength, and ergonomics, which can affect tool placement and anchor points.
- Documenting both successes and anomalies helps subsequent missions refine procedures and hardware.
- Cross-team coordination between training, engineering, and operations ensures that support teams are prepared for diverse crew needs.
Legacy and influence on later programs
Savitskaya’s EVA was referenced by later space agencies when developing mixed-gender EVA teams and when revising selection criteria to focus on task competence rather than physical stereotypes. NASA, ESA, JAXA, and other agencies used the mission’s data to inform spacesuit sizing, tool handle designs, and tether configurations. On the International Space Station, EVAs have routinely included crew members of varied backgrounds, with task assignments driven by skill and mission needs rather than gender, an approach that can be traced in part to the path first cleared in 1984.
Frequently asked questions
- How many women have performed spacewalks since 1984? Dozens of women have conducted EVAs on U.S. and Russian stations, with the number continuing to grow as missions become more gender-balanced.
- Did the first female EVA require custom tools or spacesuits? Tools were largely adapted from existing hardware, and the spacesuit was a modified Orlan-M tailored for female anthropometry, demonstrating that dedicated fit and mobility considerations were part of the planning.
- What were the main goals of the EVA on Soyuz T-12? Objectives centered on verifying that a female cosmonaut could safely perform standard EVA tasks such as tool handling, tethered movement, and operating portable workstations outside the spacecraft.
- How long did the EVA last? Approximately 3 hours and 35 minutes, timed to match workload estimates and station procedures at the time.
Bottom line
Svetlana Savitskaya’s spacewalk in July 1984 marked a durable shift in how human spaceflight prepares for and plans EVA operations. By proving that women could safely exit a spacecraft, conduct technical work, and return without incident, the mission influenced training, hardware design, and policy for decades. Its emphasis on task competence and procedural rigour remains a useful model as programs continue to integrate diverse crews and expand the scope of in-space construction and maintenance.
