NASA and Boeing teams continue to make progress in preparing for Starliner’s first crewed flight to and from the International Space Station.
In a media teleconference Aug. 8, leaders from NASA and Boeing discussed the path forward for the spacecraft, including work to address two technical issues identified during the agency’s certification process to ensure the system meets crew safety requirements.
The Starliner team expects to have the Crew Flight Test spacecraft ready in March 2024. A specific target launch date will be set closer to spacecraft readiness, and with consideration of the International Space Station, United Launch Alliance, and Eastern Range availability.
A replay of the teleconference is available on NASA’s YouTube channel.
NASA astronauts Butch Wilmore and Suni Williams are assigned to fly Starliner and United Launch Alliance Atlas V rocket to the International Space Station. The duo will remain docked at the orbiting laboratory for about two weeks to evaluate the new spacecraft and its systems before returning to Earth in the Western United States.
Following a successful first flight with crew, NASA will complete work to certify the Starliner system as an operational crew system for long-duration crew rotation missions to the space station.
NASA and Boeing hosted a media teleconference on June 1 to provide an update on the agency’s Boeing Crew Flight Test (CFT) to the International Space Station – the first flight with astronauts on the company’s CST-100 Starliner spacecraft.
During the call, managers shared they have made the decision to stand down on a July launch attempt for CFT to take time to address recent emerging issues.
CFT is the final flight test prior to regular crewed missions to the space station on the next-generation system. For CFT, the Starliner spacecraft will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, returning approximately eight days later in White Sands, New Mexico. The flight will carry two NASA astronaut test pilots, Butch Wilmore and Suni Williams, on the demonstration flight to prove the end-to-end capabilities of the Starliner system.
Following a successful test flight with astronauts, NASA will begin the final process of certifying the Starliner spacecraft and systems for regular crew rotation flights to the space station.

NASA and Boeing completed a joint Crew Flight Test checkpoint review May 25 ahead of the first flight of Starliner with astronauts to the International Space Station. During the checkpoint, mission teams reviewed open work ahead of launch planned no earlier than July 21, including emerging issues that need a path to closure prior to a decision to fuel the spacecraft in June.
“We are taking a methodical approach to the first crewed flight of Starliner incorporating all of the lessons learned from the various in-depth testing campaigns, including Starliner’s flight tests and the agency’s verification efforts,” said Steve Stich, manager of NASA’s Commercial Crew Program. “All Orbital Flight Test-2 anomalies are closed. In addition to the closeout of ongoing work, the team remains vigilant on tracking new technical issues as we complete certification for crewed flight.”
As part of the ongoing effort, 95% of the Crew Flight Test certification products are complete. This includes approval of Starliner’s crew module batteries, based on additional testing and analysis, along with post-certification flight mitigations and a proposed battery upgrade for future missions. Teams are conducting final spacecraft closeouts and preparing for upcoming hardware milestones, including spacecraft fueling, spacecraft rollout to the launch site, and integration with the United Launch Alliance Atlas V rocket.
While the team continues to work the remaining certification products, they also are working resolution paths on the following items:
Teams will remove and replace a by-pass valve on the active thermal control system, which is located on the Starliner service module and is used to flow coolant into the system to cool the onboard avionics. The Starliner team is replacing the valve that was restricting flow to one of two redundant loops, and running a diagnostic to confirm the suspected issue with the malfunctioning hardware. This work is expected to take about a week with no overall impact to the launch schedule at this time.
Engineers also are working to evaluate any elevated risk from a specific type of tape used on the spacecraft to protect wires from chafing. Although the tape is commonly used in spaceflight, the adhesive properties of the tape could present a flammability risk under certain conditions. NASA and Boeing are evaluating this material and the system’s overall wiring protection to confirm it is acceptable for crewed flight. Those efforts are ongoing and are expected to complete before Boeing begins fueling operations on the spacecraft.
NASA and Boeing also are working to reassess Starliner’s parachute system margins based on new data reviews as part of the ongoing design certification process. Engineers are reviewing the overall efficiency of certain joints within the parachute system to confirm they meet all required factors of safety for crewed flight.
“Crew safety remains the highest priority for NASA and its industry providers, and emerging issues are not uncommon in human spaceflight especially during development,” said Stich. “If you look back two months ago at the work we had ahead of us, it’s almost all complete. The combined team is resilient and resolute in their goal of flying crew on Starliner as soon as it is safe to do so. If a schedule adjustment needs to be made in the future, then we will certainly do that as we have done before. We will only fly when we are ready.”
Starliner spacecraft fueling is expected to begin as early as mid-June, and there is some operational flexibility in that timeline that can be used if needed. Teams will continue to monitor the forward work and determine whether an adjustment in the current launch date is needed. An update on the team’s progress will be provided in the coming weeks.
NASA and its industry partners, Boeing and SpaceX, are planning target launch schedules for upcoming commercial crew missions to the International Space Station.

NASA and Boeing now are targeting no earlier than Friday, July 21, for the agency’s Boeing Crew Flight Test (CFT) to the International Space Station, pending coordination for the U.S Eastern Range availability.
The new target date provides NASA and Boeing the necessary time to complete subsystem verification testing and close out test flight certification products and aligns with the space station manifest and range launch opportunities.
The goal of CFT is to test the end-to-end capabilities of the Starliner system with crew onboard, including the United Launch Alliance Atlas V rocket, from prelaunch to docking and undocking to landing and recovery. Following a successful test flight, Boeing will work to finalize operational readiness for its post-certification missions and NASA will begin the final process of certifying the Starliner spacecraft and systems for regular, crewed missions to the space station.
Certification Process Approximately 90% of the certification products required for the flight test are complete. NASA and Boeing anticipate closure on remaining CFT certification products this spring after ongoing verification testing of several subsystems is complete, including testing on the spacecraft’s backup manual flight mode for added redundancy in cases of emergency.
Starliner Status The Starliner spacecraft build is complete. The team is now working through final interior closeouts of the spacecraft and wrapping up integrated testing. The loading of cargo apart from some late-stow items also is complete. The next major hardware milestones are specific to the launch campaign timeline, such as spacecraft fueling and rolling out to the launch site.
Atlas V Status NASA completed its rocket readiness assessment, which evaluates all CFT launch vehicle segment flight critical items prior to integration activities. All rocket hardware is at Cape Canaveral Space Force Station in Florida, awaiting processing ahead of rocket stacking at the launch site.
Crew Readiness The NASA astronauts who will fly on CFT recently completed the critical Crew Equipment Interface Test. Conducted in two parts during February and March, the test allowed astronauts to perform hands-on training with the tools, equipment and hardware they will use on orbit. In the first part, they worked with the Starliner team to perform in-cabin checkouts, including adjusting the spacecraft seats, inspecting spacecraft interfaces, examining cargo, and conducting floor panel and side hatch operations. The second part of the test included the astronauts maneuvering inside the cabin with cargo installed in the spacecraft.

NASA and Boeing recently completed a full start to finish integrated mission dress rehearsal for the company’s CST-100 Starliner flight with astronauts to the International Space Station, which is scheduled to launch in April 2023.
The Crew Flight Test, or CFT, will launch NASA astronauts Barry “Butch” Wilmore and Suni Williams on Starliner – atop a United Launch Alliance Atlas V rocket – from Space Launch Complex-41 at Cape Canaveral Space Force Station as part of the agency’s Commercial Crew Program.
During several days at Boeing’s Avionics and Software Integration Lab (ASIL) in Houston, the ASIL Mission Rehearsal (AMR) combined tests of software and crew systems, along with operations teams. The completion of the end-to-end mission rehearsal clears a path for the next CFT milestones, including working with the crew and flight controllers on various integrated failure scenarios and a series of flight-day parameter updates that will become available as the team nears launch day.
“Testing is a key component to the success of a human space program,” said NASA Commercial Crew Program Software Certification Manager Chad Schaeffer. “The AMR and the integrated failure scenarios are excellent examples of the rigorous testing teams are performing on Starliner. The rehearsal went well and reflects the continued improvement in executing this test and helps pave the way to the much anticipated first crewed flight.”
During the rehearsal, Wilmore and Williams, along with fellow NASA astronaut Mike Fincke, worked through mission milestones in coordination with mission operations teams located inside flight control rooms at NASA’s Johnson Space Center. Starliner engineering teammates also supported from Boeing’s Mission Control Center located in Florida.
The crew members worked in a flight deck simulator networked to control rooms and avionics, operating the same software that will be used during CFT. They effectively demonstrated the software is ready to operate Starliner during prelaunch, launch, docking to the space station, undocking, and the return to Earth through landing.
The AMR provided end-to-end testing of hardware configuration, software, communications, preparation configuring hardware and software, routing communications channels, and mapping simulated sensor data. Similar testing was performed ahead of NASA and Boeing’s Orbital Flight Test-2 (OFT-2) uncrewed mission in early 2022.
“We began conducting AMRs with the creation of OFT-2, and the integrated team has continued to get more efficient with each rehearsal,” said Aaron Kraftcheck, Starliner avionics software integration and test manager. “With the participation of our astronauts in this CFT AMR, we have enhanced the team dynamics, and continued to learn and adjust, which is what AMR is all about.”

NASA and Boeing teams continue to conduct training and testing ahead of the Boeing Crew Flight Test (CFT), scheduled to launch in April 2023 to the International Space Station for the agency’s Commercial Crew Program.
For the crewed flight test, Boeing’s CST-100 Starliner spacecraft will launch aboard a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, returning approximately eight days later in White Sands, New Mexico.
Most recently, the CFT Super Suited Week took place at NASA’s Johnson Space Center in Houston in late October through early November. During the training, NASA astronauts Barry “Butch” Wilmore and Suni Williams, CFT commander and pilot, respectively, and Mike Fincke, CFT backup spacecraft test pilot, donned their spacesuits while participating in various simulations, good day and bad day scenarios, and spacecraft ingress and egress. The event also gave the crew extended time to get comfortable wearing their suits.
Prior to that, the astronauts participated in a crew validation test in October to evaluate and fine tune operations. These tests provide astronauts with hands-on training while giving the launch pad crew further experience with crucial tasks. In addition, teams can address issues encountered during previous checks and identify items that still need to be resolved prior to launch.
During the exercise, the astronauts suited up and tested the pressurized crew module to assess seat fit, suit functionality, cabin temperature, audio, and day of launch operations. The teams cycled through different environmental control configurations and flow rates, including oxygen and emergency gas, so the crew will be accustomed to a variety of scenarios on orbit. The astronauts also familiarized themselves with camera, tablet, and wireless application set-up. Communication checks went well between the Mission Control Center and the crew in the spacecraft.
Overall, the training activities gave the astronauts and support teams confidence in operations and built their knowledge base for subsequent flight preparation activities.
“Preparing for this flight doesn’t feel like traditional training that Suni and I went through for missions on the space shuttle or Soyuz,” Wilmore said. “We’re thoroughly embedded in all aspects of developing a brand-new spacecraft, making this more akin to an experimental process. The entire team is learning how to plan, train, and fly Starliner into space.”
Following a successful CFT mission, NASA will begin the final process of certifying the Starliner spacecraft and systems for crew missions to the space station. Regular, long-duration commercial crew rotation missions enable NASA to continue the research and technology investigations taking place aboard the orbiting laboratory. Such research benefits people on Earth and lays the groundwork for future exploration of the Moon and Mars, starting with the agency’s Artemis missions, which include landing the first woman and first person of color on the lunar surface.
NASA and its mission partners are gearing up for a busy 2023 with crew launches and returns from the International Space Station. NASA worked closely with its international partners and commercial crew providers, Boeing and SpaceX, to secure new target launch dates for the upcoming flights that are optimal for space station needs.

Starliner Flight Date Targets
NASA and Boeing now are targeting April 2023 for the agency’s Crew Flight Test (CFT), the first flight with astronauts on the company’s CST-100 Starliner. The date adjustment deconflicts visiting spacecraft traffic at the space station as NASA and Boeing work together to achieve flight readiness.
The team continues to make progress toward Starliner’s crewed flight following the successful uncrewed Orbital Flight Test-2 (OFT-2) to the space station in May. Starliner and United Launch Alliance’s Atlas V rocket hardware remain on track for readiness in early 2023. The joint team continues to close out the OFT-2 anomalies and partner closely together to identify forward work and ensure all requirements for crewed flight are met. NASA and Boeing currently are working on a variety of verification efforts across several critical systems that will be used for Starliner’s crew flight certification.
For CFT, Boeing recently completed the exterior of the Starliner crew module with the installation of the forward heat shield and entry cover. The previously flown crew module, named Calypso, will be connected to a new service module later this year. Formal qualification testing on the CFT version of Starliner’s flight software was completed last month. NASA astronauts Barry “Butch” Wilmore and Suni Williams, CFT’s commander and pilot, respectively, and Mike Fincke, backup spacecraft test pilot, along with the Boeing team, also successfully completed the crew validation test during which the astronauts suited up and tested out the pressurized crew module to ensure seat fit, suit functionality, cabin temperature, audio system and day of launch operations.
The CFT astronauts will live and work on the space station for about two weeks. Following a successful crewed flight, NASA will work to complete certification of the Starliner spacecraft and systems for regular crew rotation missions to the space station. A launch date for NASA’s Boeing Starliner-1 mission will be determined following a successful flight test with astronauts and close out of the agency’s certification work.

SpaceX Flight Date Targets
NASA and SpaceX are targeting mid-February 2023, for launch of the agency’s Crew-6 mission to the International Space Station.
A SpaceX Falcon 9 rocket will launch Dragon and NASA astronauts Stephen Bowen and Woody Hoburg, United Arab Emirates astronaut Sultan AlNeyadi, and Roscosmos cosmonaut Andrei Fedyaev to the space station from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew will spend approximately six months on the space station, starting with a short handover with Crew-5, which arrived at the station in October for a science expedition at the microgravity laboratory.
SpaceX certification and Falcon 9 hardware remain on track for the sixth crew rotation mission of the company’s human space transportation system and its seventh flight with NASA astronauts, including the Demo-2 test flight, to the space station.
The Crew-6 mission will be Dragon Endeavour’s fourth flight to the space station, which previously supported the Demo-2, Crew-2, and Axiom Mission 1 (Ax-1) missions, making the spacecraft the fleet leader in number of flights to and from the station. The Dragon spacecraft currently is undergoing refurbishment at SpaceX’s Dragonland facility at Cape Canaveral Space Force Station in Florida.
NASA and SpaceX also are targeting fall 2023 for launch of the agency’s Crew-7 mission to the International Space Station, ahead of the return of Crew-6.
