SpaceX operational astronaut launch debut back on track after “nail polish” delay
In a new NASA briefing, SpaceX vice president of build and flight reliability Hans Koenigsmann was able to explain in far more detail why a recent last-second Falcon 9 launch abort happened and how it wound up delaying the company’s first operational astronaut launch.
Now scheduled to lift off no earlier than (NET) 7:49 pm EST (00:49 UTC) on Saturday, November 14th, SpaceX’s Crew Dragon Crew-1 mission was originally expected to launch in late September, October 23rd, and October 31st. On October 2nd, however, a new Falcon 9 booster – sibling to Crew-1’s own new booster – automatically aborted its GPS III SV04 satellite launch attempt just two seconds before liftoff. The rare last-second abort was quickly blamed on “unexpected pressure rise in the turbomachinery gas generator” by CEO Elon Musk.
Likely built side-by-side with faulty GPS III SV04 Falcon 9 booster B1062 at SpaceX’s Hawthorne, California factory, Crew-1 Falcon 9 booster B1061 was almost immediately inspected to search for any commonality once the cause of the abort was better understood.
Just one week before the latest briefing, NASA human spaceflight program administrator and former Commercial Crew Program manager Kathy Lueders revealed in a statement on Twitter that SpaceX was still analyzing the cause of the abort but had already determined that at least one Crew-1 booster engine would need to be replaced, as well as one engine on Falcon 9 booster B1063.
Now, during NASA’s October 28th Crew-1 briefing, SpaceX’s Koenigsmann revealed that the company had ultimately decided to replace not one but two of Crew-1 booster B1061’s nine Merlin 1D engines. Thanks to Falcon 9’s namesake nine-engine booster design and SpaceX’s prolific rocket factory, that process was completed extraordinarily quickly, simply requiring the redirection of already qualified Merlin 1D engines from a fairly large pool. Based on Koenigsmann’s phrasing, SpaceX has already installed both replacement engines on the Crew-1 booster.
What, though, caused GPS III SV04’s launch abort and how did that affect Crew-1?
Rocket engine vs. “nail polish”
According to Koenigsmann, in the course of the rapid and complex mechanical and electrical ballet preceding Falcon 9 first stage ignition, the rocket’s autonomous flight computer observed that two of the GPS III SV04 booster’s nine Merlin 1D engines appeared to be running ahead of schedule, so to speak. The computer immediately halted the ignition process to avoid what could have otherwise been a “hard” (i.e. stressful or damaging) start. SpaceX quickly began inspecting the rocket within 24 hours but was unable to detect anything physically or electrically wrong with Falcon 9’s Merlin 1D engines and engine section.
Out of an abundance of caution, SpaceX removed both misbehaving engines and shipped them to its McGregor, Texas development and test facilities where – somewhat miraculously – the same premature startup behavior was replicated on the test stand. After a great deal of increasingly granular inspections, SpaceX finally narrowed the likely cause down to a tiny plumbing line feeding one of the engine’s gas generator relief valves. In a seemingly random subset of relatively new Merlin 1D engines, SpaceX eventually discovered that a supplier-provided relief valve line was sometimes clogged by a protective lacquer Koenigsmann likened to “red nail polish.”
Used to selectively exclude parts of the engine tubing during a surface finishing process known as anodization, the lacquer was either unsuccessfully removed on a random selection of engine parts or was accidentally channeled into a blockage by over-enthusiastic cleaning. Ultimately, for whatever, reason that miniscule blockage was enough to cause affected Merlin 1D engines to consistently attempt to ignite a tiny fraction of a second early.
Crucially, when SpaceX discovered the possible cause and cleaned out the blocked plumbing, each previously affected Merlin 1D engine performed perfectly, all but directly confirming both the cause and the cure for Falcon 9’s October 2nd abort.
Astronauts enter quarantine
In anticipation of SpaceX seemingly simple solution to the gas generator problem, NASA Commercial Crew Program manager Steve Stich revealed that SpaceX’s Crew-1 mission astronauts – Shannon Walker, Victor Glover, and Mike Hopkins, and JAXA (Japanese) astronaut Soichi Noguchi – had begun routine prelaunch quarantine procedures in anticipation of a November 14th launch.
Stich also offered a more specific Crew-1 schedule, beginning with an integrated Falcon 9 and Crew Dragon static fire test NET November 9th and a full dry dress rehearsal on November 11th before the first launch attempt on November 14th. Notably, thanks to coincidental orbital dynamics, a successful launch on November 14th would enable Crew Dragon to raise its orbit and rendezvous with the International Space Station a brisk eight and a half hours after liftoff – three times quicker than the more common 27.5-hour transit.
Stay tuned for updates as the mission’s launch date approaches.

Tesla Robotaxi app update now tells riders if Cybercab is the better choice
Tesla’s Robotaxi app now shows ETAs, wait times and availability for Cybercab and Model Y.
Tesla has rolled out a new vehicle selection screen in its Robotaxi app, and it puts the numbers riders care about most in front of them before they book.
Version 26.11.0 of the app shows the estimated arrival time, the expected wait and current availability for each vehicle option on a single screen, according to a video shared by @gheeunit on X on November 7. Riders deciding between a Cybercab and a Model Y Robotaxi can now compare those figures side by side instead of picking a car first and learning how long it will take afterward.
Tesla first gave riders that choice on September 3, the day paid Cybercab rides began in Austin. The original version of the screen listed the Cybercab, which seats two, next to the Model Y, which seats four. A later build, 26.8.2, added a seating capacity indicator so groups knew which car would fit them. What it did not show was whether choosing the Cybercab meant standing on the curb a few extra minutes.
Newest version of @robotaxi app has a new vehicle selector UI for choosing between Cybercab and Model Y and shows you the fare for both simultaneously! https://t.co/7qoDQ0vACX — mantequilla 🧈 (@gheeunit) November 7, 2026
That question matters more now than it did two months ago. Tesla had 45 Cybercabs on the Texas DMV roster when rides started. By late October the state listed 573, alongside 631 Model Ys, and community trackers logged a record 1,576 Cybercab sightings across Austin on Halloween alone. With two large fleets sharing one service area, the closest car and the quickest pickup are not always the same vehicle.
Inline availability also changes what happens when demand spikes. If no Cybercab is free nearby, the rider sees that on the selection screen rather than after trying to book one.
For now the comparison is mostly an Austin feature. Riders in Dallas, Houston, Fort Worth and the Florida markets are still matched with Model Y vehicles, though Tesla said on its third quarter earnings call that Cybercab rides would launch in Dallas this month.
The update follows a steady run of smaller changes to the rider experience. Late last month Tesla brought a quiet mode that blacks out the cabin screen to Model Y Robotaxis after first testing it in the Cybercab, and it has stretched Austin service to run from 6 a.m. to 2 a.m.
The Cybercab side of that selection screen is about to get much busier. Elon Musk said this week that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab output, and Tesla has said it is aiming to get Cybercabs to customers by the end of this year.
Tesla has not published official release notes for version 26.11.0.
Tesla is ending Cybertruck production sometime in mid-2027, according to CEO Elon Musk.
Musk made the announcement on X last night, which came as a shock to many. He said that the Cybertruck will end production “to make room for increased Cybercab production” at Gigafactory Texas.
It is a huge blow to the fans of Tesla who have come to love the Cybertruck and identify with it as a symbol of their fandom. It has been the best-selling electric pickup, but it has had an underwhelming sales performance in terms of what was expected. This is mostly due to Tesla not meeting the prices it planned to offer the Cybertruck, as its unveiling and actual release were four years apart.

Overall, the responses were mixed. Some fans understood the move toward Cybercab production, especially as Tesla is truly pushing the autonomous future through its Robotaxi platform. However, others did not understand it.
“Damn, how many Cybercabs do you guys need?” one response read. Another said it was “Sad but understandable.”Even analyst Gary Black had responded to the news, stating he hoped Tesla planned to replace it with a traditional pickup design.
It doesn’t seem like that will be the case.
Tesla is so hell-bent on delivering autonomy and eventually providing a driverless service that owning a car seems like an arbitrary idea, according to their thesis. Instead, Cybercabs will be available to pick you up and drop you off on demand, safely, without any human help.
As a result, Tesla has thinned its lineup considerably, and one can only ask where the vehicle lineup goes from here. Eventually, it seems like Cybercab could be the only vehicle that Tesla will sell.

SpaceX’s next Starship flight set to make history on Friday the 13th
SpaceX is targeting Friday, November 13 for Starship Flight 15 and its first ship catch.
SpaceX is targeting Friday, November 13 for Starship Flight 15, the mission the company plans to use for its first attempt at catching the ship itself with the launch tower.
SpaceX Vice President of Launch Kiko Dontchev shared the date on stage at the UP.Summit on Thursday, according to Ars Technica’s Eric Berger, who was in attendance. It is the first launch target to come directly from a SpaceX executive. Until now, the public schedule had relied on FAA air traffic planning slides, which listed Flight 15 for no earlier than November 8 and later November 12. SpaceX has not posted an official mission page yet, and no launch time has been shared.
The date lands inside the window Elon Musk sketched out last month. Speaking at Giga Texas on October 10, Musk said the flight would “probably launch a little bit before Thanksgiving,” as Teslarati reported. On SpaceX’s third quarter earnings call ten days later, he confirmed that Flight 15 would try to catch both the Super Heavy booster and the ship, and put the odds of a successful ship catch at “more likely than not.” SpaceX also aired an animation of the maneuver during that webcast, showing the ship swinging vertical over Starbase before dropping into the tower’s chopsticks.
The hardware is ready. Booster 22 fired all 33 of its Raptor engines for a full duration static fire at Pad 2 on October 25. Ship 42 followed with a single engine burn simulating a deorbit maneuver on October 26 and a 60 second firing of all six engines the next day, according to NASASpaceflight. Ship 42 had already rehearsed the catch in September, when the Pad 2 arms lifted it into position and crews connected the quick disconnect arm while the vehicle hung from the tower.
The remaining hurdle is regulatory. The FAA’s Starship page does not yet list a Flight 15 license. SpaceX President Gwynne Shotwell said in October that, after “significant constructive engagement with the FAA,” she expects the license to cover a return to the launch site and a tower catch for both stages. Bringing the ship home means a reentry path that heads toward land, rather than ending over open ocean as every Starship flight so far has.
SpaceX has caught Super Heavy three times, on Flights 5, 7 and 8, but the ship comes back from orbital velocity and has never been caught. Flight 14 on September 28 was the first Starship to reach orbit, deploying 26 Starlink V3 satellites before splashing down despite an early engine shutdown that Musk blamed on engine computer software.
Musk has called a successful ship catch “the first time that there’s been full recovery of an orbital class rocket,” and he has already named the step after it: a Flight 16 where both the booster and the ship fly again. NASASpaceflight reports that Ship 43, the next vehicle in line, is set for static fire testing in December.
