Expedition 71 Flight Engineers Tracy C. Dyson and Mike Barratt, both NASA astronauts, pose for preflight portraits at NASA’s Johnson Space Center in Houston, Texas.
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 after the crew sets their suits to internal battery power ahead of exiting the airlock. The spacewalk is set to last about six and a half hours.
NASA astronauts Tracy C. Dyson and Mike Barratt 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. Barratt 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 third for Barratt. It is the 271st spacewalk in support of space station assembly, maintenance, and upgrades.

NASA and Boeing leadership are adjusting the return to Earth of the Starliner Crew Flight Test spacecraft with agency astronauts Butch Wilmore and Suni Williams from the International Space Station. The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data. Listen to a full replay of the June 18 media briefing where NASA and Boeing leadership discussed the ongoing efforts.
“We are taking our time and following our standard mission management team process,” said Steve Stich, manager of NASA’s Commercial Crew Program. “We are letting the data drive our decision making relative to managing the small helium system leaks and thruster performance we observed during rendezvous and docking. Additionally, given the duration of the mission, it is appropriate for us to complete an agency-level review, similar to what was done ahead of the NASA’s SpaceX Demo-2 return after two months on orbit, to document the agency’s formal acceptance on proceeding as planned.”
A media telecon with mission leadership will follow the readiness review’s conclusion, and the agency will share those details as they are solidified. Boeing’s Starliner spacecraft remains cleared for return in case of an emergency on the space station that required the crew to leave orbit and come back to Earth.
Mission managers are evaluating future return opportunities following the station’s two planned spacewalks on Monday, June 24, and Tuesday, July 2.
“Starliner is performing well in orbit while docked to the space station,” said Stich. “We are strategically using the extra time to clear a path for some critical station activities while completing readiness for Butch and Suni’s return on Starliner and gaining valuable insight into the system upgrades we will want to make for post-certification missions.”
Wilmore and Williams remain integrated with the Expedition 71 crew, assisting with station operations as needed and completing add-on in-flight objectives for NASA certification of Starliner.
“The crew’s feedback has been overwhelmingly positive, and they know that every bit of learning we do on the Crew Flight Test will improve and sharpen our experience for future crews,” said Mark Nappi, vice president and program manager, Boeing’s Starliner Program.
The crew is not pressed for time to leave the station since there are plenty of supplies in orbit, and the station’s schedule is relatively open through mid-August.

NASA and Boeing now are targeting no earlier than Saturday, June 22, to return the agency’s Boeing Crew Flight Test mission from the International Space Station. The extra time allows the team to finalize departure planning and operations while the spacecraft remains cleared for crew emergency return scenarios within the flight rules.
NASA and Boeing leadership will discuss the details of the new return target, flight status, and weather considerations for landing during a pre-departure media teleconference at 12 p.m. EDT Tuesday, June 18. NASA will provide additional media teleconference details soon.
“We are continuing to understand the capabilities of Starliner to prepare for the long-term goal of having it perform a six-month docked mission at the space station,” said Steve Stich, manager of NASA’s Commercial Crew Program. “The crew will perform additional hatch operations to better understand its handling, repeat some ‘safe haven’ testing and assess piloting using the forward window.”
NASA and Boeing teams also prepared plans for Starliner to fire seven of its eight aft-facing thrusters while docked to the station to evaluate thruster performance for the remainder of the mission. Known as a “hot fire test,” the process will see two bursts of the thrusters, totaling about a second, as part of a pathfinder process to evaluate how the spacecraft will perform during future operational missions after being docked to the space station for six months. The crew also will investigate cabin air temperature readings across the cabin to correlate to the life support system temperature measurements.
“We have an incredible opportunity to spend more time at station and perform more tests which provides invaluable data unique to our position,” said Mark Nappi, vice president and program manager, Commercial Crew Program, Boeing. “As the integrated NASA and Boeing teams have said each step of the way, we have plenty of margin and time on station to maximize the opportunity for all partners to learn – including our crew.”
NASA astronauts Butch Wilmore and Suni Williams, who are serving as Starliner’s crew for the mission, arrived at the International Space Station on June 6. They’ve completed numerous flight objectives required for NASA certification of Boeing’s transportation system for flights to the orbiting laboratory under the agency’s Commercial Crew Program.
Over the past three days, Wilmore and Williams have performed tasks as part of the space station team, including installing research equipment, maintaining the lab’s hardware, and helping station crewmembers Matt Dominick and Tracy Dyson prepare for a spacewalk. After NASA called off Thursday’s spacewalk, Williams worked to help the crew out of their spacesuits.
Engineering teams continue to increase their understanding of previous observations from Starliner propulsion systems on the spacecraft’s service module.
Pending spacecraft return readiness and acceptable weather conditions, Starliner will undock from the space station for a parachute and airbag-assisted landing in the southwestern United States.
