NASA Decides to Bring Starliner Spacecraft Back to Earth Without Crew
Stephanie Plucinsky Posted on August 24, 2024
NASA will return Boeing’s Starliner to Earth without astronauts Butch Wilmore and Suni Williams aboard the spacecraft, the agency announced Saturday during a news conference. The uncrewed return allows NASA and Boeing to continue gathering testing data on Starliner during its upcoming flight home, while also not accepting more risk than necessary for its crew. The news conference is available here.
Wilmore and Williams, who flew to the International Space Station in June aboard NASA’s Boeing Crew Flight Test, have been busy supporting station research, maintenance, and Starliner system testing and data analysis, among other activities.
“Spaceflight is risky, even at its safest and most routine. A test flight, by nature, is neither safe, nor routine. The decision to keep Butch and Suni aboard the International Space Station and bring Boeing’s Starliner home uncrewed is the result of our commitment to safety: our core value and our North Star,” said NASA Administrator Bill Nelson. “I’m grateful to both the NASA and Boeing teams for all their incredible and detailed work.”
Wilmore and Williams will continue their work formally as part of the Expedition 71/72 crew through February 2025. They will fly home aboard a Dragon spacecraft with two other crew members assigned to the agency’s SpaceX Crew-9 mission. Starliner is expected to depart from the space station and make a safe, controlled autonomous re-entry and landing in early September.
NASA and Boeing identified helium leaks and experienced issues with the spacecraft reaction control thrusters on June 6 as Starliner approached the space station. Since then, engineering teams have completed a significant amount of work, including reviewing a collection of data, conducting flight and ground testing, hosting independent reviews with agency propulsion experts, and developing various return contingency plans. The uncertainty and lack of expert concurrence does not meet the agency’s safety and performance requirements for human spaceflight, thus prompting NASA leadership to move the astronauts to the Crew-9 mission.
“Decisions like this are never easy, but I want to commend our NASA and Boeing teams for their thorough analysis, transparent discussions, and focus on safety during the Crew Flight Test,” said Ken Bowersox, associate administrator for NASA’s Space Operations Mission Directorate. “We’ve learned a lot about the spacecraft during its journey to the station and its docked operations. We also will continue to gather more data about Starliner during the uncrewed return and improve the system for future flights to the space station.”
Starliner is designed to operate autonomously and previously completed two uncrewed flights. NASA and Boeing will work together to adjust end-of-mission planning and Starliner’s systems to set up for the uncrewed return in the coming weeks. Starliner must return to Earth before the Crew-9 mission launches to ensure a docking port is available on station.
“Starliner is a very capable spacecraft and, ultimately, this comes down to needing a higher level of certainty to perform a crewed return,” said Steve Stich, manager of NASA’s Commercial Crew Program. “The NASA and Boeing teams have completed a tremendous amount of testing and analysis, and this flight test is providing critical information on Starliner’s performance in space. Our efforts will help prepare for the uncrewed return and will greatly benefit future corrective actions for the spacecraft.”
NASA’s Commercial Crew Program requires spacecraft fly a crewed test flight to prove the system is ready for regular flights to and from the space station. Following Starliner’s return, the agency will review all mission-related data to inform what additional actions are required to meet NASA’s certification requirements.
The agency’s SpaceX Crew-9 mission, originally slated with four crew members, will launch no earlier than Tuesday, Sept. 24. The agency will share more information about the Crew-9 complement when details are finalized.
NASA and SpaceX currently are working several items before launch, including reconfiguring seats on the Crew-9 Dragon, and adjusting the manifest to carry additional cargo, personal effects, and Dragon-specific spacesuits for Wilmore and Williams. In addition, NASA and SpaceX now will use new facilities at Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida to launch Crew-9, which provides increased operational flexibility around NASA’s planned Europa Clipper launch.
The Crew-9 mission will be the ninth rotational mission to the space station under NASA’s Commercial Crew Program, which works with the American aerospace industry to meet the goal of safe, reliable, and cost-effective transportation to and from the orbital outpost on American-made rockets and spacecraft launching from American soil.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon where the agency is preparing for future human exploration of Mars.

The moon setting over the Pacific.
Went to the cupola to shoot Tropical Storm Hone near Hawaii but right after we passed by the storm the moon started to set.
400mm, ISO 500, 1/20000s shutter speed, f2.8, cropped, denoised.
Andrew McCarthy
@AJamesMcCarthy
Excellent detail for 400mm. Do I assume 1/20000 is a typo?
Matthew Dominick
@dominickmatthew
Not a typo. f2.8 is a contributor. Also shooting bracketed shots at (5F, 1EV steps, 20 fps) because the moon sets quickly due to our orbital speed. Not a lot of time to adjust settings. Best just to shoot a lot. Sometimes the -2EV or -1EV turn out better. Camera in spot metering with auto focus and metering on moon. This was the -2EV shot.

In the absence of the live video stream, I've been watching the ISS-Mimic data to follow along with the deployment of the ArgUS payload adapter out to the Bartolomeo platform. What I think they've done so far:
- SSRMS removed the Bishop airlock from the port end berthing port on Node 3.
- The airlock was handed off to the MBS Payload ORU Accommodations (POA) LEE.
- SSRMS picked up Dextre from the Node 2 PDGF.

Monday Sees Physical Science Prep and Training for Station Crew
Abby Graf Posted on August 26, 2024
A suite of training and conferences kept the International Space Station residents busy on Monday as they embark on a new week of work in microgravity. Though a light duty science day, some crew members did schedule in time to assess how spaceflight affects the human body and prep for upcoming physical science investigations.
In the morning, NASA astronaut Jeanette Epps set up hardware for the CIPHER investigation and then conducted an exam on NASA astronaut Mike Barratt to assess how microgravity affects the vestibular system, including spatial orientation, cognitive function, and changes in head-eye coordination.
NASA astronaut Tracy C. Dyson spent some time in the Tranquility module troubleshooting the toilet pressure sensor, then replaced experiment samples and igniter tips in SoFIE, a physical science payload used to study the ignition and flammability of spacecraft materials. Meanwhile, NASA astronaut Matthew Dominick spent some time replacing Packed Bed Retractor Experiment hardware, another physical science investigation that looks at the behaviors of gases and liquids in microgravity.
Boeing Crew Flight Test Commander Butch Wilmore and Pilot Suni Williams spent Monday powering up communication software and holding a conference with ground teams as they begin their formal integration into the Expedition 71/72 crew.
NASA announced on Saturday that Boeing’s Starliner spacecraft will return to Earth uncrewed, allowing the agency and Boeing to continue gathering testing data on Starliner during its upcoming flight home, while also not accepting more risk than necessary for its crew. Wilmore and Williams will continue their work aboard the orbiting laboratory through February 2025 and fly home aboard a Dragon spacecraft with two other crew members assigned to the agency’s SpaceX Crew-9 mission. Starliner is expected to depart from the space station and make a safe, controlled autonomous re-entry and landing in early September. Since their arrival, the duo has been supporting station research, maintenance, Starliner system testing, and a host of other orbital activities.
To prepare for upcoming missions in September, Barratt, Epps, Dyson, Dominick, Wilmore, and Williams, along with cosmonaut Alexander Grebenkin, all completed a round of SpaceX Dragon overview training throughout the day. The septet then joined forces in the evening to review Dragon emergency procedures and hold a conference with ground teams to discuss future Dragon configuration.
Afterward, the septet was joined by station Commander Oleg Kononenko and Flight Engineer Nikolai Chub of Roscosmos to discuss emergency response and coordination amongst all crew members.
Kononenko and Chub also partnered throughout the day to inspect and replace hardware in the Zvezda service module and install software to a few station computers.
Soyuz MS-26 prime and backup crew members flew to their launch site in Baikonur, Kazakhstan to begin final prelaunch training ahead of the launch of NASA astronaut Don Pettit and Roscosmos cosmonauts Alexei Ovchinin and Ivan Vagner, currently scheduled for Wednesday, Sept. 11.

So sad to see her all broken up about being stranded on the ISS.
On the contrary, she looks like she's in her Happy Place!!

Now that the video feed is back up, some screenshots from the ongoing ROBO ops:
1) Wide shot showing the Bishop airlock on the MBS POA.
2) Dextre cam view, with the end CBM on Node 3 (where Bishop was removed from) visible.
3) Camera pans up - good view of Endeavour.
4) Camera looks into airlock, revealing two ArgUS multi-payload adapters.

5) Dextre lines up to retrieve one of the ArgUS plates.
6) Grappling ArgUS.
7) Withdrawing ArgUS - looks like this one has just the one, low-profile payload attached on the left side of that center fin.
8) In transit over to the Bartolomeo platform, with a certain misbehaving crew capsule in the background.

9) Cygnus NG-21 makes a cameo appearance, along with the Quest airlock and that one flappy panel on the radiator.
10) Looking up at the underside of the Columbus lab, including the Bartolomeo platform. The camera then zoomed in for survey photography, including...
11) The ColKA antenna installed by Mike Hopkins and Victor Glover back on EVA-69 in January 2021.
12) The Multineedle Langmuir Probe (mNLP) Experiment, installed in September 2023 (the first payload to be deployed on Bartolomeo).
13) The arm which is eventually supposed to hold a laser / optical communications system.
14) Last up, one last angle with a slightly better view of the payload installed on the ArgUS adapter - no distinguishing markings, though. (Airbus's LinkedIn page indicates that this one is ArgUS 2-1, launched on NG-21, while the other plate with more payloads on it is ArgUS 1-1, launched on CRS-30.)

Another BCPA pump R&R is in progress for the urine processor. I've lost count at this point. When the next NASA press conference occurs, someone needs to ask about the 50% increase on use/wear and tear on the systems (urine processing, CO2 filtration, exercise equipment, etc) that are currently happening. Nice to have ISS Youtube feed back up.
