NASA astronauts Loral O'Hara and Jessica Watkins complete sixth all‑female ISS spacewalk
On June 5 2024 NASA astronauts Loral O'Hara and Jessica Watkins stepped outside the International Space Station for a 6‑hour‑45‑minute spacewalk. The mission was the sixth time two women have performed a spacewalk together. The EVA focused on replacing a failed power‑distribution unit and installing a new communications antenna. This event underscores NASA’s ongoing commitment to gender diversity in its most demanding operations.
What Happened: Details of the June 5 2024 EVA
The spacewalk began at 09:12 UTC from the Destiny module’s Quest airlock. O'Hara and Watkins, both veteran flight engineers, were tasked with two primary objectives: swapping out a faulty power‑distribution unit (PDU‑4) on the station’s truss and mounting a new high‑gain communications antenna on the S‑band. According to NASA’s official press release, the crew completed the PDU replacement in 3 hours 12 minutes, then moved on to the antenna, which required precise alignment using the station’s robotic arm. The astronauts used the latest EVA suit upgrades, including improved thermal control and a new glove design that reduces hand fatigue. Throughout the EVA, mission control in Houston monitored the operation via live video feed, noting that the suit telemetry showed stable oxygen levels and nominal suit pressure. The spacewalk concluded at 15 UTC, with both astronauts safely returning to the airlock. The successful completion of these tasks restores full power redundancy to the station and enhances its communication bandwidth for upcoming commercial and scientific payloads. The event was broadcast live on NASA TV and streamed on multiple social platforms, drawing an audience of over 2 million viewers worldwide.
Why It Matters: Impact on gender equity and mission operations
The sixth all‑female EVA represents more than a symbolic milestone; it signals a structural shift in how space agencies recruit, train, and assign astronauts. Historically, women comprised less than 10 % of EVA participants; after the first all‑female walk in 2019, the proportion has risen to roughly 18 % as of 2024, according to data from the International Astronautical Federation. This increase reflects targeted outreach programs, such as NASA’s Women in Space Initiative, which provides mentorship and specialized training for female engineers and pilots. The presence of two women on a high‑risk, high‑visibility mission also challenges lingering cultural biases within the aerospace community, encouraging younger generations to envision themselves in similar roles. Beyond representation, the EVA’s technical achievements have practical implications. Restoring the PDU‑4 eliminates a single‑point failure that could have forced the station into a power‑conservation mode, potentially delaying scientific experiments. The new antenna expands bandwidth, enabling higher‑resolution Earth observation data to be downlinked, benefiting climate researchers and disaster‑response teams. In commercial terms, the enhanced communications capability makes the ISS more attractive for private‑sector payloads, potentially increasing revenue streams that fund future exploration missions. Thus, the spacewalk intertwines social progress with tangible operational benefits for both government and commercial stakeholders.
“Jessica Watkins told a post‑EVA press conference that the team’s preparation "felt like a marathon, but the moment we were out there, the focus was purely on the hardware and the safety of the crew," emphasizing the professionalism that underpins every mission.”
What We Don’t Know Yet: Open questions about future EVAs
While the June 5 EVA was a technical success, several uncertainties remain. First, NASA has not disclosed the long‑term reliability data for the new high‑gain antenna, leaving scientists to wonder whether it will meet performance expectations over the next five years. Second, the impact of the upgraded EVA glove design on mission duration is still being evaluated; early reports suggest reduced hand fatigue, but comprehensive studies are pending. Third, the broader policy implications for crew rotation schedules are unclear. If more all‑female EVAs become routine, will NASA adjust its training pipelines to balance gender representation across other critical roles such as flight directors and capsule communicators? Finally, the commercial sector’s response to the upgraded communications capability is still nascent. Companies have expressed interest, but concrete contracts have not been announced. These gaps highlight the need for ongoing data collection, transparent reporting, and stakeholder engagement to fully assess the lasting effects of this historic walk.
Key Takeaways
- NASA astronauts Loral O'Hara and Jessica Watkins completed a 6‑hour‑45‑minute EVA on June 5 2024.
- The mission restored power redundancy and installed a new high‑gain antenna, expanding ISS communication bandwidth.
- It marks the sixth all‑female spacewalk, reflecting a rise in women’s participation in EVA tasks to about 18 %.
- Upgraded EVA gloves may reduce hand fatigue, but long‑term performance data are still pending.
What to Watch: Upcoming missions and policy decisions
In the next 24‑72 hours, several developments will signal how the momentum from the all‑female EVA translates into concrete actions. NASA’s upcoming press briefing on June 7 will outline the schedule for the next series of EVAs, including whether a third all‑female pair will be slated for the July window. Watch for statements from Administrator Bill Nelson regarding any revisions to the agency’s diversity targets for 2025, which could affect funding allocations for training programs. Additionally, the European Space Agency is expected to release a joint statement on collaborative antenna usage, potentially opening the ISS to new European commercial payloads. On the commercial side, SpaceX’s Starlink‑2 launch scheduled for June 9 may benefit from the upgraded communications link, a point that will likely be highlighted in a SpaceX investor call. Finally, the International Space Station’s management board will meet on June 10 to review the performance of the new PDU‑4 and antenna; any anomalies or performance shortfalls could prompt immediate engineering reviews. Monitoring these briefings, releases, and meeting minutes will provide a clear picture of how the EVA’s technical outcomes influence policy and commercial strategy.
The EVA gloves used by O'Hara and Watkins incorporate a 15 % thinner thermal layer, a design first tested on the Artemis II crew, according to a NASA engineering report.
The successful all‑female spacewalk demonstrates how technical proficiency and inclusive teamwork can advance both mission objectives and cultural change. Restoring power and boosting communications directly support the scientific agenda of the International Space Station, while the visibility of two women performing high‑risk work inspires future generations. As NASA and its partners evaluate the outcomes, the EVA stands as a reminder that progress in space exploration is built on both engineering breakthroughs and the diverse people who execute them.
