The ULA Atlas V rocket was moved into the company’s Vertical Integration Facility at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, which starts the preparations for its stacking operations ahead of NASA’s Boeing Crew Flight Test.

The rocket’s main stage was transferred from the nearby Advanced Spaceflight Operations Center to the integration facility Wednesday, Feb. 21, where it will await integration with the rocket’s upper Centaur stage and Starliner. The spacecraft will carry NASA astronauts Suni Williams and Butch Wilmore to the orbiting laboratory for a short stay of about one to two weeks before returning to a landing site in the southwest United States.

The mission will test the end-to-end capabilities of the Starliner system, including launch, docking, and a return to Earth. After successful completion of the mission, NASA will begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

NASA and Boeing are targeting no earlier than late April for launch. Starliner completed two uncrewed flight tests, including Orbital Flight Test-2, which docked to the space station on May 21, 2022, and provided valuable data leading up to its first crewed flight.

NASA astronauts Suni Williams and Butch Wilmore successfully completed an integrated crew exercise simulation that moves Boeing’s Starliner spacecraft one step closer to its first flight with astronauts to the International Space Station.

Targeted for launch no earlier than mid-April 2024, NASA’s Boeing Crew Flight Test (CFT) will fly Williams and Wilmore to the orbiting laboratory for about up to two weeks. They will evaluate Starliner and its systems before returning to Earth in the Western United States. Liftoff will be aboard a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.

Completing the simulation Wednesday at NASA’s Kennedy Space Center in Florida marks another milestone toward CFT launch. The integrated exercise involved participation from the flight crew, NASA, Boeing, and ULA, and allowed teams to rehearse prelaunch operations beginning roughly four hours before a targeted liftoff. The exercise began with Wilmore and Williams walking through suit-up procedures inside the Astronaut Crew Quarters in NASA Kennedy’s Neil Armstrong Operations and Checkout building.

Following this, they took an elevator down to the ground floor and exited the same double doors they will on launch day where their crew transportation vehicle was waiting to transport them to the launch pad. The crew and support teams then convoyed to the launch pad, where Williams and Wilmore supported operations from the white room – an area at the end of the launch tower’s crew access arm that will provide access to the spacecraft. The remainder of the rehearsal involved the crew traveling back to NASA Kennedy to support from Boeing’s Mission Control Center.

Over the next several weeks, teams will run through additional simulations focused on each phase of the mission. Some upcoming milestones include CFT certification, fueling Starliner with propellants, and stacking Starliner on the Atlas V rocket before rolling out to the launch pad in preparation for liftoff.

Starliner completed two uncrewed flight tests: Orbital Flight Test-2, which launched from Cape Canaveral and completed its space station mission in May 2022, and Orbital Flight Test-1, which provided teams with additional flight data in December 2019. During these two uncrewed missions, the end-to-end capabilities of the spacecraft were successfully tested.

NASA and Boeing teams are preparing for a flight test no earlier than mid-April in which the Starliner spacecraft will carry two NASA astronauts to the International Space Station.

Teams have made significant progress in resolving technical issues identified during the agency’s flight certification process. Following a successful drop test earlier this month in which recent modifications to Starliner’s parachute system were validated, NASA and Boeing are working to perform final analysis of the test data and complete overall system certification ahead of Starliner’s first crewed flight. This standard NASA process is designed to independently verify Starliner’s parachute system meets crew safety requirements and is expected to continue over the next six to eight weeks.

Meanwhile, Boeing completed removal of P213 tape that may have posed a flammability risk in certain environmental conditions. Boeing removed more than 17 pounds, or roughly 4,300 feet, of the material from the Starliner crew module. For areas in which removal of the tape carried an increased risk to Starliner hardware, Boeing applied tested remediation techniques such as overwrapping the P213 tape with another non-flammable, chafe-resistant tape, and installing fire breaks on wire harnesses. The agency worked to clarify the properties and safe usage guidance relative to P213 tape in the NASA Materials Usage Agreements database to prevent a similar misapplication from occurring across industry in the future.

Additionally, major integrated flight operations exercises are underway. Mission support teams recently completed a two-day undock to landing mission dress rehearsal with recovery personnel on the ground at White Sands Missile Range in New Mexico. Teams simulated Crew Flight Test procedures and spacecraft sequences starting with pre-undock powerup and continuing through undock, entry, landing, and crew recovery. The exercise provided an additional training opportunity for NASA and Boeing to practice Starliner’s return to Earth in a high-fidelity environment before the flight.

Teams from ULA (United Launch Alliance) are preparing the Atlas V rocket hardware for processing and spacecraft integration. Boeing is targeting completion of Starliner assembly at the end of January. The upgraded parachutes were delivered and installed on the spacecraft, along with Starliner’s forward heat shield and ascent cover. Prior to fueling operations, following final installation of thermal protection system blankets and internal closeout work, Boeing will begin flowing a nitrogen purge into the Starliner’s service module to ensure ambient moisture does not permeate into the propulsion isolation or active thermal control system valves. In the weeks ahead, NASA and Boeing will work to identify any remaining work before loading Starliner propellant.

The next couple of months teams will:

  • work to complete overall Crew Flight Test certification;
  • put the finishing touches on the Starliner spacecraft, which is already joined to its service module;
  • run simulations of operational conditions to rehearse every phase of the mission with the crew, flight controllers, and ground operations teams;
  • fuel the spacecraft with propellants for its onboard thrusters for in-space maneuvering;
  • stack the ULA Atlas V rocket and Starliner spacecraft before rolling them to the pad at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida;
  • and work through detailed systems reviews, culminating with a flight readiness review in the days before launch to verify the system and teams are ready.

Starliner’s Crew Flight Test will launch NASA astronauts Butch Wilmore and Suni Williams to the orbiting laboratory for a stay of one to two weeks before returning them to a landing in the southwest United States. The mission will mirror the tasks of regular crew rotation flights for Boeing’s Starliner under contracts with NASA’s Commercial Crew Program.

CSA (Canadian Space Agency) astronaut Joshua Kutryk has been selected as a mission specialist for NASA’s Boeing Starliner-1 mission – the first crew rotation flight for the spacecraft to the International Space Station.

Kutryk joins Scott Tingle and Mike Fincke of NASA, who will serve as the CST-100 Starliner spacecraft commander and pilot, respectively, for the mission. Both astronauts have previously flown as crew members aboard the space station. This will be Kutryk’s first spaceflight. The final crew assignment for Starliner-1 will be announced following review and approval by the agency and its international partners.

Starliner-1 will launch following the successful completion of NASA’s Boeing Crew Flight Test (CFT), with NASA astronauts Butch Wilmore and Suni Williams,  which aims to demonstrate Starliner’s ability to achieve NASA certification and safely fly regular crewed missions to space station. Kutryk is the capsule communicator for ascent and re-entry of the CFT mission, relaying communication from Mission Control at the agency’s Johnson Space Center in Houston to the astronauts aboard the spacecraft.

NASA and Boeing are targeting the Starliner-1 launch no earlier than the beginning of 2025 on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The four astronauts will join an expedition crew aboard the space station.

NASA and Boeing are working to complete the agency’s verification and validation activities ahead of Starliner’s first flight with astronauts to the International Space Station. While Boeing is targeting March to have the spacecraft ready for flight, teams decided during a launch manifest evaluation that a launch in April will better accommodate upcoming crew rotations and cargo resupply missions this spring.

Once the spacecraft meets the agency’s safety requirements, NASA’s Boeing Starliner Crew Flight Test (CFT) will see astronauts Butch Wilmore and Suni Williams perform the first crewed mission of the spacecraft designed to take astronauts to and from the orbital laboratory.

Ahead of CFT, Boeing has completed P213 tape removal in the upper dome of the Starliner crew compartment and work is underway to remove or remediate the tape in the lower dome of the spacecraft. These hardware remediation efforts inside the Starliner production facility at NASA Kennedy are expected to be completed during the next several weeks. After the P213 tape remediation efforts conclude, engineers will conduct final assessments to ensure acceptable risk of any remaining tape.

A set of parachutes is on track to be delivered and installed on the CFT spacecraft by the end of this year to support the current target launch date. Separately, the team also is planning a drop test of Starliner’s updated drogue and main parachutes. The parachutes will incorporate a planned strengthening of main canopy suspension lines and the recent design of the drogue and main parachute soft-link joints, which will increase the safety factor for the system. The drop test is planned for early 2024 based on the current parachute delivery schedule.

Boeing and NASA also are planning modifications to the active thermal control system valves to improve long-term functionality following a radiator bypass valve issue discovered during ground operations earlier this year. As discussed during a Starliner media teleconference in June, teams have modified the spacecraft hardware and identified forward work to prevent a similar issue in the future. Options include a system purge to prevent stiction, component upgrades and operational mitigations.

Additionally, about 98% of the certification products required for the flight test are complete, and NASA and Boeing anticipate closure on remaining CFT certification products early next year. Meanwhile, NASA and Boeing have made significant progress on requirement closures related to manual crew control of the spacecraft and abort system analysis.

The latest version of Starliner’s CFT flight software completed qualification testing and is undergoing standard hardware and software integration testing inside Boeing’s Avionics and Software Integration Lab. Starliner’s crew and service modules remain mated and await continuation of standard preflight processing.

The United Launch Alliance Atlas V rocket also is in Florida at Cape Canaveral Space Force Station awaiting integration with the spacecraft.

The NASA astronauts who will fly aboard CFT continue to train for their roughly eight-day mission to the orbiting laboratory, which includes working with operations and mission support teams to participate in various simulations across all phases of flight.

Starliner completed two uncrewed flight tests, including Orbital Flight Test-2, which docked to the space station on May 21, 2022, following a launch two days prior from Kennedy. The spacecraft remained docked to space station for four days before successfully landing at the White Sands Missile Range in New Mexico.
