NASA’s coverage is underway on NASA+, NASA Television, YouTube, the NASA app, and the agency’s website as two astronauts will conduct a spacewalk outside of the International Space Station. The spacewalk is scheduled to begin at 8 a.m. EDT and last about six and a half hours.
NASA astronauts Tracy C. Dyson and Matt Dominick will exit the station’s Quest airlock to complete the removal of a faulty electronics box, called a radio frequency group, from a communications antenna on the starboard truss of the space station. The pair also will collect samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory.
Dyson will serve as spacewalk crew member 1 and will wear a suit with red stripes. Dominick will serve as spacewalk crew member 2 and will wear an unmarked suit. U.S. spacewalk 90 will be the fourth for Dyson and the first for Dominick. It is the 271st spacewalk in support of space station assembly, maintenance, and upgrades.
Astronaut Tracy C. Dyson works inside the Quest airlock and checks procedures on a computer tablet to prepare a spacesuit for a fit verification.
The Expedition 71 crew is in final preparations for a science and maintenance spacewalk set to begin Thursday morning. The two astronauts on NASA’s Boeing Crew Flight Test spent their day aboard the International Space Station performing genetic sequencing and orbital plumbing.
NASA astronauts Tracy C. Dyson and Matthew Dominick are in their final day of preparations for a spacewalk planned to start at 8 a.m. EDT on Thursday. Once the astronauts set their spacesuits to battery power, the spacewalkers will exit the Quest airlock into the vacuum of space for six-and-a-half hours of maintenance and science work. The duo will first remove the radio frequency group hardware from a pallet on the side of the Destiny laboratory module with assistance from the Canadarm2 robotic arm. Next, the spacewalkers will swab surfaces on the Destiny and Quest modules to determine if microorganisms released through station vents can survive the external microgravity environment.
Dyson and Dominick readied Quest, checked their spacesuits, and organized spacewalking tools on Wednesday morning. NASA Flight Engineers Mike Barratt and Jeanette Epps practiced on a computer the Canadarm2 maneuvers they will use during Thursday’s spacewalk. All four astronauts at the end of the day called down to mission controllers for a final spacewalk preparedness conference.

Orbiting Earth as part of the nine-person crew of the International Space Station, NASA astronauts Butch Wilmore and Suni Williams continue testing Boeing’s Starliner spacecraft as part of its first flight with astronauts. The testing is part of the data collection on the Starliner system for certification by NASA for regular crewed mission to the orbital complex.
As part of NASA’s Boeing Crew Flight Test, Wilmore and Williams, along with teams on the ground, are stepping through numerous flight objectives following arrival of Starliner to the space station on June 6, including:
Powering the spacecraft down into a minimal power mode, which it will enter during operational missions while the crew works aboard station, and then powering it up again;
Conducting “safe haven” checks to show the spacecraft can support a crew with its own air and consumables during in an emergency on the station;
Performing a habitability study, along with astronauts Tracy Dyson and Matthew Dominick,to evaluate seating positions and other factors, such as air circulation for a four-person crew;
Evaluating spacesuit and seat-fits, as well as checkouts of the service module’s batteries.
Meanwhile, ground teams continue to assess and monitor Starliner’s performance and planning for return of the mission no earlier than Tuesday, June 18, pending weather and spacecraft readiness. Starliner is cleared for crew emergency return scenarios from space station, if needed, in accordance with the flight rules.
While Starliner remains docked to station, ground teams are continuing to evaluate propulsion system in-flight observations.
“Butch and Suni are doing great aboard station as ground teams continue digging into the details of Starliner’s on-orbit, rendezvous, and docked performance,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We expected to do a lot of valuable learning on this test flight, and I am extremely proud of how the NASA and Boeing teams are working together to ensure we can safely execute the return portion of the mission.”
One of Starliner’s aft-facing reaction control system (RCS) thrusters, capable of about 85 pounds of thrust, remains de-selected as teams continue to evaluate its performance. Ground teams plan to fire all 28 RCS thrusters after undocking to collect additional data signatures on the service module thrusters before the hardware is expended. As part of normal operations, the service module separates from crew module on return, so NASA and Boeing will gather as much data as possible to aid in system assessments.
Teams currently are assessing what impacts, if any, five small leaks in the service module helium manifolds would have on the remainder of the mission. Engineers evaluated the helium supply based on current leak rates and determined that Starliner has plenty of margin to support the return trip from station. Only seven hours of free-flight time is needed to perform a normal end of mission, and Starliner currently has enough helium left in its tanks to support 70 hours of free flight activity following undocking. While Starliner is docked, all the manifolds are closed per normal mission operations preventing helium loss from the tanks.
Engineers also are evaluating an RCS oxidizer isolation valve in the service module that is not properly closed. Ground teams performed a successful propulsion system valve checkout on Sunday. All other oxidizer and fuel valves within the service module were cycled normally. The suspect oxidizer isolation valve was not cycled in the recent checkout. It will remain commanded closed for the remainder of the mission while ground teams continue to evaluate its data signatures. The crew module propulsion valves, which are part of an independent system that steers the capsule in the last phase of flight before landing, also were successfully cycled, and all those valves are performing as designed.
Mission managers are continuing to work through the return plan, which includes assessments of flight rationale, fault tolerance, and potential operational mitigations for the remainder of the flight. NASA and Boeing will hold a pre-departure media teleconference to provide additional updates before Starliner undocks from station.
With launch and docking already completed, the last remaining dynamic phase of the mission will come at the end of the flight test when Starliner will undock from the orbiting laboratory and then adjust its orbit to move away from the space station. The spacecraft, with Wilmore and Williams aboard, will perform a deorbit burn before entering the atmosphere and landing in the southwestern United States under parachutes and landing airbags to complete the flight.
As part of the agency’s Commercial Crew Program, the mission is the first crewed flight for the Starliner spacecraft. Learn more about the mission by following the commercial crew blog,@commercial_crew on X, and commercial crew on Facebook.

NASA Flight Engineers Tracy C. Dyson and Matthew Dominick are preparing for the first of three planned spacewalks for science and maintenance on the orbital lab. The astronauts are expected to set their spacesuits to battery power at 8 a.m. EDT on Thursday officially beginning their scheduled six-and-a-half-hour spacewalk. The spacewalkers will retrieve faulty communications hardware, also known as the radio frequency group, and swab station surfaces to determine the ability of microorganisms to survive the extreme microgravity environment.
Mission managers will discuss the upcoming spacewalk details during a news conference at 4 p.m. on Tuesday. Live coverage will air on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.
NASA Flight Engineer Mike Barratt assisted Dominick as he tried on his spacesuit during a standard fit check in the Quest airlock on Monday morning. During the afternoon, the two spacewalkers joined Barratt and NASA Flight Engineer Jeanette Epps and reviewed Canadarm2 robotic arm procedures necessary to retrieve the radio gear.
Earlier, Epps attached an acoustic monitor to herself measuring the sound environment she’s exposed to aboard the station. Afterward, she collected lab water samples to test for microbes then conducted a hearing exam listening to tones on a pair of headphones connected to a computer. Dyson joined cosmonaut Nikolai Chub at the end of the day and peered at a standard eye chart reading characters to test their visual acuity.
New station visitors Butch Wilmore and Suni Williams, both veteran NASA astronauts, learned on Sunday they will orbit Earth until June 18 before returning home aboard Boeing’s Starliner spacecraft. The extra days in space will allow teams more time to checkout Starliner’s systems and free up the Expedition crew’s schedule for more spacewalk preparations.
Wilmore and Williams started Monday with health checks measuring their temperature, blood pressure, pulse, and respiratory rate. The duo then split up as Wilmore worked on computer maintenance inside the Microgravity Science Glovebox and Williams installed hardware to support a space fire investigation.
In the orbital outpost’s Roscosmos segment, Chub transferred water stowed inside the Progress 88 resupply ship to tanks inside the Zvezda service module. Flight Engineer Alexander Grebenkin cleaned vents and air ducts then checked lighting systems in the Zvezda, Nauka, and Poisk modules. Station commander and veteran cosmonaut Oleg Kononenko studied plasma physics in the Columbus laboratory module then wore a sensor-packed cap and explored futuristic spacecraft and robotic piloting techniques.
