NASA Astronaut Spacewalk Outside ISS Postponed Over ‘Spacesuit Discomfort Issue’

NASA’s plans for a spacewalk outside the International Space Station (ISS) have been temporarily delayed due to a “spacesuit discomfort issue.” The announcement, made through a post on X (formerly Twitter) by the ISS, has left the space community awaiting further updates on the rescheduled event. This spacewalk, which marks the 90th for the U.S., was intended to address several critical tasks on the ISS.

Planned Tasks for the Spacewalk

The scheduled spacewalk was to feature NASA astronauts Tracy C. Dyson and Matt Dominick, who were set to exit the ISS’ Quest airlock. Their mission included removing a faulty electronics box from a communications antenna located on the starboard side of the station. This task is essential for maintaining the ISS’s communication capabilities, which are vital for both everyday operations and emergency situations.

In addition to this technical task, the astronauts planned to collect samples from the exterior of the ISS. These samples are crucial for scientific research aimed at understanding how microorganisms survive and reproduce in the harsh conditions of space. This knowledge could have significant implications for future long-duration space missions and the potential for life in space.

Postponement Details

The exact nature of the “spacesuit discomfort issue” has not been disclosed, but such concerns are not uncommon in the meticulous and safety-conscious environment of space exploration. Spacesuit integrity and astronaut comfort are paramount, as even minor issues can escalate into significant problems in the vacuum of space.

NASA has yet to announce a new date and time for the postponed spacewalk. Once rescheduled, the event will be streamed live across multiple platforms, including NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. This accessibility allows the public to witness these critical operations firsthand.

The Astronauts Involved

Tracy C. Dyson

Tracy C. Dyson is a seasoned astronaut, currently on her third trip to space. She has been on the ISS since March 2024 and this would have been her fourth spacewalk. Dyson will be identifiable by the red stripes on her spacesuit. Her extensive experience makes her a key player in maintaining and upgrading the ISS.

Matt Dominick

Matt Dominick, the commander of the SpaceX Crew-8 mission, is also aboard the ISS since March 2024. This postponed spacewalk would have been his first. Dominick will wear an unmarked suit. Despite his relative inexperience with spacewalks, his role as a mission commander speaks to his capabilities and importance to the ISS operations.

Boeing Starliner Astronauts

Adding to the complexity and collaborative spirit of this mission, astronauts Suni Williams and Butch Wilmore from Boeing’s Starliner spacecraft have extended their stay at the ISS to assist with the spacewalk. Initially scheduled to stay for just a week following their successful launch and docking, their return to Earth has now been postponed to no earlier than Tuesday, June 18. Their extended presence underscores the collaborative efforts necessary to ensure mission success and safety.

Importance of Spacewalks

Spacewalks, or extravehicular activities (EVAs), are critical for the maintenance and advancement of the ISS. They allow astronauts to perform tasks that cannot be done from inside the station, such as repairs, upgrades, and scientific experiments. Each spacewalk is meticulously planned and rehearsed to ensure the safety of the astronauts and the success of the mission.

The postponement of a spacewalk, while not uncommon, highlights the inherent challenges of operating in space. Every aspect of an EVA, from the astronauts’ physical condition to the performance of their equipment, must be in perfect working order. The rigorous checks and balances in place are designed to prevent any potential issues from escalating during the actual spacewalk.

How to Watch the Rescheduled Spacewalk

Once a new date and time for the spacewalk are set, NASA will provide live coverage of the event. This live stream will be accessible on several platforms, including:

  • NASA+
  • NASA Television
  • NASA app
  • YouTube
  • NASA’s official website

These platforms will offer real-time updates and coverage, allowing viewers to follow the progress of Dyson and Dominick as they perform their tasks outside the ISS.

The Future of U.S. Spacewalks

Following the completion of the 90th spacewalk, NASA will announce the astronauts who will participate in the 91st and 92nd U.S. spacewalks, scheduled for June 24 and July 2, respectively. These upcoming spacewalks are expected to build on the tasks and objectives of the 90th, further ensuring the operational integrity and scientific productivity of the ISS.

The Role of Spacewalks in Scientific Research

One of the significant aspects of spacewalks is their contribution to scientific research. The samples collected by astronauts during EVAs provide invaluable data on the behavior of microorganisms in space. This research can lead to a better understanding of the potential for life in space and help develop measures to protect astronauts during long-duration missions.

Additionally, spacewalks often involve installing or repairing scientific instruments that contribute to a wide range of research, from climate science to physics. These instruments provide data that is not only crucial for scientific discovery but also for improving life on Earth.


The postponement of the 90th U.S. spacewalk due to a “spacesuit discomfort issue” is a reminder of the meticulous care and preparation required for space missions. As NASA works to reschedule the spacewalk, the importance of these activities in maintaining the ISS and advancing scientific knowledge remains clear. With astronauts Tracy C. Dyson and Matt Dominick poised to undertake this mission, and the support of their colleagues on the ISS, the space community eagerly awaits the continuation of this critical work.

The forthcoming spacewalks, along with the invaluable contributions of astronauts like Dyson and Dominick, demonstrate the ongoing commitment to exploration, discovery, and international cooperation in space. As we look forward to the rescheduled spacewalk, the broader implications for science, technology, and human achievement in space continue to inspire and drive forward the mission of space exploration.
