One road into a city isn't enough — and NASA knew it.
On the eve of a long-anticipated launch from Cape Canaveral, NASA and Boeing teams rehearsed the final countdown for the Starliner Crew Flight Test — a mission carrying astronauts Butch Wilmore and Suni Williams to the International Space Station aboard a vehicle that has never before carried human beings. Though a valve problem delayed the attempt, the deeper significance held: for the first time since the shuttle era ended in 2011, Mission Control in Houston would direct a crewed launch, and for the first time since SpaceX's Dragon began flying NASA crews in 2020, America would have a second certified path to orbit. In the long arc of human spaceflight, redundancy is not a luxury — it is the architecture of resilience.
- A valve fault on the Atlas V rocket scrubbed the May 6 launch attempt, halting a mission years in the making just hours before ignition.
- The stakes extend well beyond a single flight — NASA currently depends entirely on SpaceX Dragon for crew access to the ISS, a single point of failure that Starliner's certification would eliminate.
- Johnson Space Center's White Flight Control Room is managing a crewed launch for the first time in thirteen years, a symbolic and operational return that underscores how much has changed since the shuttle's retirement.
- Canadian astronaut Josh Kutryk, serving as capcom, identified the orbital insertion burn at 31 minutes post-launch as the mission's most critical moment — the threshold between vulnerability and stability.
- The scrub is a pause, not a defeat: the Starliner-1 crew is already assigned, the follow-on capsule is built, and a successful CFT would unlock expanded docking access and long-duration ISS stays.
On the Sunday before a planned Monday night launch, NASA and Boeing controllers at Johnson Space Center ran a full simulated countdown for the Starliner Crew Flight Test — powering up the Atlas V and Starliner stack, testing communications, and walking through hundreds of verification procedures. It was as close to the real thing as possible without lighting the engines. The launch, set for 10:34 p.m. Eastern from Pad 41 at Cape Canaveral, was ultimately scrubbed due to a valve problem on the United Launch Alliance Atlas V. The delay, however, did nothing to diminish what the mission represents.
Aboard Starliner would be NASA astronauts Butch Wilmore and Suni Williams — both former Navy test pilots, and the first humans ever to fly the vehicle. Their roughly ten-day trip to the International Space Station is the Crew Flight Test, or CFT, designed to certify Starliner as NASA's second commercial crew option alongside SpaceX's Dragon. Canadian Space Agency astronaut Josh Kutryk, present at the Cape and assigned as capcom for the launch, was direct about the strategic importance: with only Dragon currently certified, NASA has a single point of access to the ISS. Starliner changes that.
The mission also marks a historic return for Mission Control. JSC's White Flight Control Room hasn't directed a crewed launch since the shuttle program ended in 2011 — SpaceX manages its own launches from California. For the first time in thirteen years, Houston would be calling the shots.
Kutryk, who is himself assigned to Starliner-1 — the first full operational mission, targeted for no earlier than 2025 — described the capcom role as the connective tissue between crew and ground: verifying systems, checking suits, tracking abort options in the Atlantic until the critical orbital insertion burn 31 minutes after launch. That burn, he said, is the moment that matters most.
Starliner's path here was hard-won. A software error stranded its first uncrewed test in 2019 in the wrong orbit. A second uncrewed attempt in 2022 succeeded. CFT is the next deliberate step — and a successful outcome would open additional docking ports on the ISS and pave the way for the months-long stays that operational missions demand. The scrubbed launch was a delay. The mission, and the strategic architecture it represents, remains very much alive.
Down at Cape Canaveral on a Sunday in early May, the people responsible for putting two astronauts aboard a brand-new spacecraft were doing what launch teams always do the day before: running through it one more time. NASA and Boeing controllers gathered at Johnson Space Center in Houston and simulated a full countdown for Boeing's Starliner, all the way to the moment of liftoff — a dry run for a mission that, if it worked, would change the shape of American human spaceflight.
The mission in question is the Crew Flight Test, or CFT — a roughly ten-day trip to the International Space Station carrying NASA astronauts Butch Wilmore and Suni Williams, both former U.S. Navy test pilots. They would be the first humans to fly aboard Starliner, and the first to ride an Atlas V rocket. The plan called for launch Monday night, May 6, at 10:34 p.m. Eastern, from Pad 41 at Cape Canaveral Space Force Station. That launch was ultimately scrubbed due to a valve problem on the United Launch Alliance Atlas V, but the weight of what the mission represented didn't go anywhere.
Canadian Space Agency astronaut Josh Kutryk was at the Cape for all of it, speaking by phone from near the press center. His role during the actual launch would be capcom — capsule communicator, the person whose voice the crew hears from the ground. It's one of the most consequential seats in Mission Control, and Kutryk was plainspoken about why the mission itself mattered beyond the technical achievement. Starliner, he said, is the second major piece of America's strategy for reaching low Earth orbit, following SpaceX's Dragon. Without it, NASA has only one commercial option for getting its astronauts to the station.
That strategic logic is what gives CFT its stakes. SpaceX has been flying NASA crews since 2020, and Dragon is proven. But relying on a single provider for something as operationally critical as crew access to the ISS is a vulnerability. Starliner's certification would give NASA a backup — and more than a backup, a genuine alternative. Kutryk put it directly: this is important strategically.
The Sunday simulation was thorough. Controllers powered up the Atlas V and Starliner stack on the pad, tested communications systems, and walked through hundreds of pages of technical verification procedures. The CFT crew sat this one out — they had their own pre-launch tasks — but the exercise was otherwise as close to the real thing as you can get without actually lighting the engines. Come Monday, the launch team would return to the White Flight Control Room at JSC around 4 p.m. Eastern, take control of the vehicle from Boeing, and begin fueling. Wilmore and Williams would be strapped into their seats roughly three hours before launch.
What made the moment additionally notable was the venue. NASA's Johnson Space Center hasn't managed a crewed launch from its White Flight Control Room since the space shuttle program ended in 2011. SpaceX runs its own launches from a separate facility in Hawthorne, California. For the first time in thirteen years, Mission Control in Houston would be calling the shots on a crew going to orbit.
Kutryk described the capcom role in practical terms: talking to the crew, talking to the technicians strapping them in, verifying that complex systems and simple ones alike are functioning. Pressure checks on the vehicle, pressure checks on the suits. The moment he called most critical would come about 31 minutes after launch — the orbital insertion burn that would place Starliner in a stable orbit. Until that burn, the team would be tracking potential abort sites in the Atlantic. After it, they'd have options.
Kutryk has more than a passing interest in how all this goes. He is assigned to Starliner-1, the first full operational mission, currently scheduled for no earlier than 2025. That mission will fly a new physical capsule — already built and sitting inside Boeing's facility. The Starliner-1 crew, which includes NASA's Mike Fincke as commander and Scott Tingle as a crew member, has completed its ISS certification. Fincke was quarantining with the CFT crew at Kennedy Space Center in the days before launch, serving as their backup.
Starliner's road to this point was not smooth. A software error on its first uncrewed test in 2019 left the spacecraft stranded in the wrong orbit, never reaching the station. A second uncrewed attempt in 2022 succeeded. CFT is the next step in a deliberate build-up approach — each mission expanding what the vehicle is certified to do. A successful CFT would open the door to docking at additional ports on the ISS's Harmony module, and eventually to the kind of long-duration stays, measured in months rather than days, that operational missions require. The scrubbed launch was a delay, not a verdict. The mission, and what it means for NASA's options in low Earth orbit, remains very much in play.
Citas Notables
This is the second big piece of America's overall strategy for access to low Earth orbit, after implementing SpaceX's Dragon.— Josh Kutryk, Canadian Space Agency astronaut and CFT capcom
That orbital insertion burn is really critical for the whole mission — it puts the crew in a sustainable, safe orbit where we have a lot more options and flexibility.— Josh Kutryk, paraphrased
La Conversación del Hearth Otra perspectiva de la historia
Why does it matter so much that there's a second commercial crew vehicle? SpaceX Dragon already works.
It matters for the same reason you don't want a single road into a city. Dragon works, but if something grounds it — a technical issue, a contract dispute, anything — NASA has no other way to get its people to the station.
So this is really about redundancy more than competition?
Partly. But certification also changes what NASA can negotiate, what it can plan around. Having two providers shifts the whole conversation.
Kutryk is capcom for the launch but also assigned to the next mission. Is that unusual?
It's actually a smart arrangement. He's learning the vehicle from the inside out in real time, not just in simulation. By the time Starliner-1 flies, he'll have lived through a launch on console.
The orbital insertion burn 31 minutes after launch — why is that the hinge point?
Before that burn, you're in a temporary trajectory with limited options. After it, you're in a stable orbit and you have time to think, to troubleshoot, to adapt. The whole ascent team is essentially working toward that moment.
Johnson Space Center hasn't run a crewed launch since 2011. Does that gap matter operationally?
The people are trained, the procedures exist. But there's something real about doing it live after thirteen years. The simulation on Sunday was partly about shaking that rust loose.
Starliner's history includes a pretty significant failure in 2019. How much does that shadow this mission?
It's present. The software that sent the spacecraft to the wrong orbit has been redesigned. But the program has been methodical — two uncrewed flights before putting people on board. That caution is itself a response to what happened.
What changes if CFT succeeds?
Practically, it unlocks more docking ports and longer stays at the station. Strategically, it means NASA has two certified paths to orbit. That's a different world than the one they're in right now.
