NASA’s human spaceflight management team provided a media update Aug. 14 on the agency’s Boeing Crew Flight Test at the International Space Station. The group, including the Associate Administrator for Space Operations Ken Bowersox, highlighted the role safety plays as a core value at NASA and how safety guides the decision-making process for the mission.

The panel also touched on numerous aspects of the Crew Flight Test as NASA and Boeing evaluate the Starliner testing data generated over the past few weeks ahead of the agency’s Commercial Crew Program control board. NASA then plans to hold a readiness review where agency leadership will finalize the plan to return astronauts Butch Wilmore and Suni Williams from the space station. Following the readiness review, mission leadership will host a televised briefing to discuss the decision and path forward.

Listen to a full replay of the media update. Other briefing participants included:

  • Joel Montalbano, deputy associate administrator, NASA’s Space Operations Mission Directorate
  • Russ DeLoach, chief, NASA’s Office of Safety and Mission Assurance
  • NASA chief astronaut Joe Acaba
  • Emily Nelson, chief flight director, NASA’s Flight Operations Directorate

Although no final decisions have been made, teams are evaluating returning Wilmore and Williams aboard the Starliner spacecraft. In parallel, NASA also is looking more closely at the capability to return the crew as part of the agency’s SpaceX Crew-9 mission. Crew-9 will launch no earlier than Tuesday, Sept. 24, and return to Earth in February 2025.

While work continues on Earth to analyze the Starliner spacecraft and its systems, Wilmore and Williams continued their work aboard the International Space Station. Since the mission is a flight test, the crew has undergone rigorous training for any duties or issues that may arise, and the astronauts are well prepared for all situations.

The main goal of the agency’s Commercial Crew Program is two unique human spaceflight systems. Should any one system encounter an issue, NASA still has the capability to launch and return crew members to ensure safety and a continuous human presence aboard the station.

The International Space Station is the world’s leading space laboratory where researchers conduct cutting-edge research and technology development that will enable human and robotic exploration of destinations beyond low Earth orbit, including the Moon and Mars.

Astronauts Butch Wilmore and Suni Williams, crew members of NASA’s Boeing Crew Flight Test mission, performed a host of research activities and other roles aboard the International Space Station. Wilmore and Williams give the microgravity laboratory a complement of nine people working through daily tasks.

On Monday, Wilmore and Williams reviewed the procedures for using the Fluid Systems Servicer, which drains, purges, and circulates fluids on systems aboard the space station. Wilmore then refilled coolant loops in the water pump assembly located in the Columbus module. Tuesday saw the pair take turns during the morning pedaling on an exercise cycle while attached to heart and breathing sensors that measured their aerobic capacity. The duo then split up as Wilmore serviced a pair of research freezers that preserve scientific samples and Williams installed hardware on an experiment that explores atmospheric reentry and thermal protection systems.

The seven-member Expedition 71 crew joined the two Boeing Crew Flight Test astronauts to practice an emergency drill in collaboration with mission controllers. The teams aboard the orbital outpost and on the ground coordinated communications and reviewed procedures in the unlikely event of a pressure leak, chemical leak, or fire aboard the space station. Following that, Wilmore and Williams spoke to reporters from the space station, answering questions about their mission and the Starliner vehicle. NASA and Boeing managers also discussed the Crew Flight Test mission with the media in an audio teleconference afterward. Watch the crew news conference here and listen to the media briefing here. The duo also completed life support work refilling temperature loops with water in the Tranquility module’s internal thermal control system.

Advanced biology research also was underway aboard the orbiting lab on Thursday with astronauts exploring how living in space affects the human body and mind. Williams extracted DNA to identify microbe samples collected from station water systems. Results from the genetic biotechnology experiment may improve ways to keep crews healthy and spacecraft systems clean on future missions.

NASA astronaut Michael Barratt also assisted Wilmore, who spent all day servicing a pair of spacesuits in the Quest airlock. The duo cleaned the suits’ cooling loops and checked the communication systems ahead of a spacewalk planned for July 29.

NASA, Boeing Update Starliner Crew Flight Test Return from Station

The Starliner spacecraft on NASA’s Boeing Crew Flight Test is pictured docked to the Harmony module’s forward port as the International Space Station orbited 263 miles above the Mediterranean Sea.

Teams from NASA and Boeing now are targeting no earlier than 10:10 p.m. EDT Tuesday, June 25, for the undocking of the Starliner spacecraft from the International Space Station. For the primary undocking opportunity, NASA astronauts Butch Wilmore and Suni Williams, the first crew to fly aboard Starliner, would land about 4:51 a.m. on Wednesday, June 26, at White Sands Space Harbor in New Mexico.

Mission teams supporting NASA’s Boeing Crew Flight Test continue to review Starliner’s data from the completed test objectives.

During a media teleconference on Tuesday, Steve Stich, manager of NASA’s Commercial Crew Program, discussed the flight test and upcoming return plans. Stich was joined by Dana Weigel, manager of NASA’s International Space Station Program; Mike Lammers, flight director at NASA’s Johnson Space Center in Houston; and Mark Nappi, vice president and manager of Boeing’s Commercial Crew Program. Listen to a full replay of the teleconference.

Following undocking and the deorbit burn, Starliner will descend under parachutes to land in the desert grounds of White Sands. Airbags attached to the bottom of Starliner will soften the spacecraft’s touchdown. The landing will mark the first time an American capsule has touched down on land with astronauts aboard. A team of NASA and Boeing specialists will retrieve the crew soon after landing.

Wilmore and Williams docked the Starliner spacecraft to the space station’s forward port on June 6 and have been testing spacecraft systems and performing tasks aboard the orbiting laboratory.

The United Launch Alliance Atlas V rocket booster has separated from the Centaur upper stage carrying Boeing’s Starliner spacecraft. The Centaur will continue to help propel Boeing’s Starliner to a suborbit before the spacecraft boosts itself to orbit, bringing it closer to the International Space Station. 

Measuring 10 feet in diameter and 41.5 feet in length, the Centaur upper stage uses liquid hydrogen and liquid oxygen to power its twin Aerojet Rocketdyne RL10A-4-2 engines. The burn of the Centaur’s dual engines is expected to last a little more than seven minutes before engine cutoff and separation from Starliner. Following separation, the crew capsule carrying NASA astronauts Butch Wilmore and Suni Williams will be on its own for the remainder of the journey to the space station. 

Following its separation, the Atlas Centaur will land in the ocean near Australia. 

NASA Television will provide continuous coverage leading up to docking at the space station and through hatch opening and welcome remarks.
