At our factory in Decatur, Alabama, skilled technicians are putting the finishing touches on the CFT hardware before shipment to the Cape Canaveral launch site, and also working on the assembly and testing of the PCM-1 rocket.
These launches will be the second and third flights of the Starliner program. The first flight, the Orbital Flight Test (OFT), will be an uncrewed checkout mission to the International Space Station scheduled for August 2019. All Atlas V hardware for OFT is in Cape Canaveral and will soon begin processing for the first flight.The Atlas first stage for CFT is in final processing in Decatur. Photo credit: ULA
The CFT launch vehicle, designated AV-082, is in final processing in Decatur and will soon travel to Florida in the Mariner cargo ship. The Atlas V first stage and the Dual Engine Centaur (DEC) upper stage are fully assembled and now undergoing closeouts in preparation to depart the factory.
The PCM-1 rocket, designated AV-085, is making great strides in its manufacturing. The first stage tanks have been completed and the Dual Engine Centaur is in the final assembly cleanroom.

For each Starliner launch, the Atlas V first stage will fire for four-and-a-half minutes before separating. The DEC then ignites its twin Aerojet Rocketdyne RL10 engines for a burn lasting more than seven minutes to put the spacecraft on the trajectory to reach the International Space Station.
CFT will carry Boeing astronaut Chris Ferguson and NASA astronauts Mike Fincke and Nicole Mann for an extended duration test flight to live and work aboard the station. The trio is undergoing training at the Johnson Space Center in Houston, learning the intricate details of Starliner's systems and operational information about the station facility. Fincke and Mann are training to conduct spacewalks at the station, while Ferguson is rehearsing his support role from inside the complex.Both Centaurs for CFT and PCM-1 sit side-by-side in the Clean Room in the factory.

PCM-1 will be NASA's first operational mission on Starliner, taking astronauts Suni Williams and Josh Cassada on a long duration expedition to the orbiting laboratory.
Starliner, and the United Launch Alliance Atlas V rockets that will launch the spacecraft, are key elements of NASA's Commercial Crew Program to restore the capability to send astronauts into orbit from U.S. soil.
Feb. 18, 2019 -- The joint team that will launch the United Launch Alliance Atlas V rocket and Boeing’s CST-100 Starliner on its Orbital Test Flight conducted a successful Integrated Crew Exercise (ICE) on Feb. 12.
ULA, Boeing, NASA and Air Force personnel executed a mock countdown that practiced fueling the rocket and operating on the unique launch day timeline that features a four-hour built-in hold at the T-minus 4 minute mark. The Blue Team entered Space Launch Complex-41 and took the Crew Access Tower elevator to the White Room for simulated work to ready the Starliner’s crew module for flight.
The team was given simulated issues with hardware and downrange assets to exercise troubleshooting, problem resolution procedures and the coordination that goes into adjusting the countdown as necessary. There were even simulated challenges from the weather, forcing officials to react to a changing weather conditions at the pad.
The exercise culminated with a successful liftoff and climb into space.
Participants were in various locations just like they will be on the day of launch, including Cape Canaveral Air Force Station and Kennedy Space Center in Florida, Denver, Colorado and Johnson Space Center in Houston, Texas.
Formal rehearsals like this one allow the combined organizations to practice as one team, demonstrate the roles and responsibilities of each team member and practice the countdown scripts.
Leading the Atlas V countdown were ULA Chief Launch Conductor Doug Lebo, ULA Launch Director Bill Cullen and ULA Anomaly Chief Dave McFarland. Key personnel leading CST-100 Starliner activities were Spacecraft Mission Director LeRoy Cain at the Cape, Spacecraft Launch Conductor Louis Atchison at Boeing Mission Control at NASA’s Kennedy Space Center and Flight Director Richard Jones in the Mission Control Center at NASA’s Johnson Space Center in Houston. Commercial Crew astronaut Mike Fincke also participated in the simulation.
The OFT will be the uncrewed test of the CST-100 Starliner spacecraft under NASA’s Commercial Crew Program. Starliner will launch to the International Space Station for an automated rendezvous and docking, complete a short stay and then return to Earth.
Feb. 13, 2019 -- Watch the episode where a rocket scientist (Tory Bruno, ULA CEO and President) and an Astronaut (Chris Ferguson, Boeing Astronaut) discuss the Atlas V Starliner, Star Wars and Star Trek, favorite moments leading to launch, their excitement about launch day and more.
Dec. 11, 2018 -- All launch vehicle hardware has been delivered to Cape Canaveral for the United Launch Alliance Atlas V rocket to launch Boeing’s first CST-100 Starliner spacecraft on its uncrewed Orbital Flight Test.
The Atlas V first stage rolled off of the Mariner cargo vessel on Dec. 7 at the Cape Canaveral wharf for the short drive to the Atlas Spaceflight Operations Center for receiving inspections and checkout.
Mariner is the ocean-going vessel that ULA uses to transport rocket stages from the manufacturing plant in Decatur, Alabama to the launch sites. The Atlas stage departed the factory Nov. 28 for the journey of nearly 2,000 miles.
Early in 2019, the stage will move further north to the Vertical Integration Facility to be raised on the mobile launch platform. The twin solid rocket boosters will be mounted to the bottom of the first stage. Then, the top of the rocket stack, which consists of the interstage, Centaur upper stage and payload adapter, will be hoisted into position.
This delivery means all of the hardware that ULA needs to launch the first Starliner has been received at the launch site for final integration.
Nov. 29, 2018 -- The dual-engine Centaur upper stage that will power Boeing’s first CST-100 Starliner crew capsule into space for its Orbital Flight Test is one step closer to launch.
Inside a ULA launch site test cell, the Centaur has been hoisted upright and attached to the interstage adapter that supports the stage atop the Atlas V rocket’s first stage during the initial minutes of launch. The Launch Vehicle Adapter (LVA) was mated to the forward end of Centaur and provides the mechanical interface to attach Starliner.
This three-piece combined element is called the OVI stack, or Off-site Vertical Integration, for the Atlas V rocket’s launch campaign. It will be driven to the Vertical Integration Facility and lifted atop the first stage when the time comes.
The Atlas V program evolved to OVI stacking operations in 2015 to improve launch processing techniques and enable schedule efficiencies. This process eliminates several days of lifting operations at the VIF that would require acceptable weather to stack each structure separately.
The Centaur was built at ULA’s manufacturing facility located in Decatur, Alabama. It arrived at Cape Canaveral aboard the Mariner cargo ship on Oct. 19 and spent two weeks undergoing receiving activities at the Atlas Spaceflight Operations Center before the short drive to the Delta Operations Center to begin the OVI assembly sequence. The LVA arrived at the Cape on Nov. 12.
Centaur will separate from the interstage adapter during in-flight staging before igniting its twin RL10A-4-2 engines more than four minutes after liftoff. Starliner will be released from the Launch Vehicle Adapter when the spacecraft separates from the Atlas V to conclude the launch.
Nov. 15, 2018 -- An elite group of United Launch Alliance (ULA) specialists will serve as an ascent flight control team during launches of Boeing’s Starliner spacecraft aboard Atlas V rockets.
Stationed in the Vehicle Ascent and Launch Operations Room (VALOR) at ULA’s Denver headquarters, this dedicated team will monitor the health and performance of the Atlas V rocket during every Starliner capsule’s climb to space.
The safety of astronauts is paramount in the return of human spaceflight launch capabilities to the United States, and ULA’s VALOR team takes this responsibility seriously. The highly trained engineers staffing the consoles will provide real-time status of the Atlas V vehicle and assist in making real-time decisions with Boeing’s flight director at Mission Control in Houston.
“This ULA Ascent Team in the VALOR is Boeing’s and the flight crew’s insight into the launch vehicle during ascent. If you compare it to the space shuttle program, we are equivalent to the BOOSTER position in Mission Control,” said Gregory Plettinck, the Ascent Room Coordinator (ARC).
VALOR is located in the Denver Operations Support Center, which provides engineering expertise during all ULA launches. This new room is isolated to ensure no distractions to the engineers’ work that goes beyond the normal level of ascent data monitoring.
Console positions will monitor all critical systems, like avionics, the engines, fuel tanks and the vehicle navigation. They also will be supplying confirmation of launch ascent events to Mission Control in Houston, such as engine ignitions, throttling events and cutoffs, and the jettisoning of the twin solid rocket boosters, the first stage, aeroskirt and Starliner itself.
“The team undergoes extensive training and all members must be certified to properly carry out their roles on day of launch. The safety of the flight crew depends on them,” said ULA Mission Manager Caleb Weiss.
In addition, VALOR will offer situational awareness of any off-nominal launch vehicle data in the telemetry stream from the rocket and prompt the engineers to report flight rule violations if they occur.
“In the event of a developing anomaly, the team will provide a recommendation to the flight director in Houston on the course of action to best keep the crew safe,” Weiss said.
The VALOR will be available to support other missions that use an Ascent Team such as the ULA-made Interim Cryogenic Propulsion Stage on NASA’s Space Launch System.
Nov. 12, 2018 –The Launch Vehicle Adapter (LVA) that will attach Boeing’s first Starliner spacecraft to the Atlas V launch vehicle arrived at Cape Canaveral from the United Launch Alliance factory today.
The Mariner cargo vessel brought the LVA and two stages of a Delta IV rocket from our manufacturing plant in Decatur, Alabama. The ship, which was purpose-built to transport the large diameter Delta IV stages to Florida and California launch sites, set sail on Nov. 3 and traveled nearly 2,000 miles, arriving Nov. 11.
Technicians unloaded the elements today and they were transported for the LVA to begin integrated operations with the Centaur upper stage.
The LVA is the specially-designed structure that will be fitted to the top of Centaur. It will soon be attached to the Centaur during pre-launch stacking operations and eventually support the Starliner spacecraft during launch of the Orbital Flight Test next year.
Also part of the LVA is the aeroskirt, which ULA designed in collaboration with Boeing and NASA for added aerodynamic stability during the flight. This metallic orthogrid structure will smooth the air flow over the Starliner-Atlas V vehicle, and will be nominally jettisoned after the first stage of flight. The aeroskirt also has provisions for venting in the event the Starliner abort engines are fired.
OFT, the precursor to Boeing’s Crew Flight Test, is being performed in partnership with NASA’s Commercial Crew Program to return the nation’s human spaceflight launch capability.
Oct. 25, 2018 -- Barry “Butch” Wilmore, the NASA astronaut who piloted shuttle Atlantis’ STS-129 flight and commanded Expedition 42 on the International Space Station, stopped by ULA today to check out the dual-engine Centaur upper stage and engage with employees working on the Commercial Crew Program.
Oct. 19, 2018 -- The dual-engine Centaur upper stage that will launch Boeing's first Starliner spacecraft on its uncrewed Orbital Flight Test to the International Space Station has arrived at Cape Canaveral for final processing by United Launch Alliance technicians.
The stage arrived Oct. 19 aboard the Mariner cargo ship, the ocean-going vessel that ULA uses to transport rocket stages from the manufacturing plant in Decatur, Alabama to the launch sites.
Wrapped in a protective covering for the transit, the Centaur was offloaded at the Port Canaveral wharf and driven on a specialized trailer to ULA's Atlas Spaceflight Operations Center for initial arrival checks.
Later, it will move to the Delta Operations Center to be raised vertically, mounted onto the interstage structure and fitted with the adapter that will support Starliner atop the rocket. That combined stack will then be ready for mating to the Atlas V first stage at the Vertical Integration Facility next year.
Mariner left Decatur on Oct. 10 for the journey of nearly 2,000 miles.
The venerable Centaur will resume flights in a dual-engine configuration -- which was once commonplace -- for this inaugural launch of Starliner. The last Centaur stage to utilize two engines was an Atlas IIAS rocket launch in 2004.
The Atlas V has needed only single-engine Centaurs to perform all of its launches to date to deliver payloads to their intended destinations, but the Starliner mass along with the need to shape the trajectory to limit astronaut accelerations and optimize ascent abort performance in case of a vehicle failure necessitates the thrust of two engines.
For the OFT launch, the Centaur will be powered by a pair of Aerojet Rocketdyne RL10A-4-2 cryogenic engines, burning liquid oxygen and liquid hydrogen to generate nearly 45,000 pounds of thrust.
Centaur flew for the 250th time on Oct. 17 in launching the Air Force's AEHF-4 protected communications satellite. Two-thirds of those previous launches were dual-engine configurations.
The high-energy stage has launched spacecraft to every planet in our solar system, plus the moon, Pluto and solar observatories, and critical national security, communications and weather satellites.
