Watch SpaceX’s Inspiration4 mission launch four private astronauts live [webcast]
Update: SpaceX, Falcon 9, Crew Dragon, the crew, and the weather remain on track for the company’s historic Inspiration4 mission, which is set to become the first dedicated orbital space tourism launch in history.
SpaceX has begun more than four hours of live coverage for the mission, which remains on track to launch no earlier than just before 8:03 pm EDT (00:03 UTC). Tune in below to watch the launch live!
In less than 12 hours, SpaceX will kick off a more than four-hour webcast covering Crew Dragon’s historic Inspiration4 mission – set to be the world’s first all-private orbital astronaut launch and the highest private citizens have ever flown.
Safely tucked inside a once-flown orbital Dragon capsule and riding on a twice-flown Falcon 9 booster, the latter a first for SpaceX, Inspiration4’s approximately five-hour launch window is scheduled to open just before 8:03 pm EDT on Wednesday, September 15th (00:03 UTC 16 Sept). Barring weather or technical delays (or clouds in general), a liftoff ~35 minutes after sunset could produce spectacular views for anyone watching from the ground as Falcon 9 and its immense exhaust plume ascend back into sunlight.
No matter the view, though, Inspiration4 will be a milestone both for SpaceX, spaceflight, and orbital tourism as a whole.
The mission will both be SpaceX’s first private astronaut launch of any kind and the first all-private orbital astronaut launch in history. In a single mission, SpaceX will singlehandedly boost the number of private astronauts that have reached orbit by 50% – a feat only eight other people have achieved. If all goes according to plan, it will also be the first time ever that private citizens have successfully flown to orbit and back on or in a flight-proven rocket or flight-proven spacecraft.
According to SpaceX, Falcon 9 will launch Crew Dragon to an apogee of around 575 km (~357 mi) – more than a third higher than the ISS, the highest humans have flown since 2009, and the highest altitude ever reached by private astronauts. With Inspiration4, SpaceX will also launch astronauts on a twice-flown Falcon 9 booster and simultaneously operate three Dragon spacecraft in orbit for the first time ever, pushing the company’s own technical abilities forward.
Despite the myriad impressive firsts Inspiration4 is set to mark, one thing is certain: it won’t be the last time private astronauts head to (real) space on a SpaceX spacecraft. Already, SpaceX has contracts from Axiom Space for four dedicated private launches to the International Space Station in 2022 and 2023, each carrying up to four private astronauts. Space Adventures – responsible for organizing all eight other non-SpaceX private orbital astronaut launches in history – also has plans to launch a private crew of four to unprecedented heights, though it’s unclear if the mission has secured any customers.
I asked about future non-government missions for SpaceX:

In an official Q&A held on Tuesday, Benji Reed – SpaceX director of Dragon mission management – said that the company’s “Dragon manifest is getting busier by the minute” with “a growing backlog of commercial astronaut mission.” Reed also expects SpaceX to soon be capable of a minimum of 4-6 Dragon launches annually. Axiom-1, the first fully private astronaut mission to the International Space Station (ISS), is scheduled to launch no earlier than January 2022.
As for Inspiration4, Jared Isaacman, Sian Proctor, Haley Arceneaux, and Chris Sembroski will spend a bit less than three days in orbit and are expected to perform a few small science experiments, take plenty of photos, and host a couple live events over the course of the mission. They’ll also get to take advantage of Crew Dragon’s ‘cupola’ – designed specifically by SpaceX for Inspiration4 and set to be the largest window ever flown in space. A small camera inside the nosecone that will protect that window during ascent and reentry will hopefully allow the crew to take self-portraits with Earth as a spectacular backdrop.
If all goes according to plan, Dragon will reenter and return its private astronauts to Earth around 7pm EDT on Saturday, September 18th. SpaceX is expected to provide live coverage of Inspiration4’s launch and reentry and the launch webcast will begin around 4pm EDT (20:00 UTC), four hours before liftoff.

Starlink passes 9 million active customers just weeks after hitting 8 million
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
SpaceX’s Starlink satellite internet service has continued its rapid global expansion, surpassing 9 million active customers just weeks after crossing the 8 million mark.
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
9 million customers
In a post on X, SpaceX stated that Starlink now serves over 9 million active users across 155 countries, territories, and markets. The company reached 8 million customers in early November, meaning it added roughly 1 million subscribers in under seven weeks, or about 21,275 new users on average per day.
“Starlink is connecting more than 9M active customers with high-speed internet across 155 countries, territories, and many other markets,” Starlink wrote in a post on its official X account. SpaceX President Gwynne Shotwell also celebrated the milestone on X. “A huge thank you to all of our customers and congrats to the Starlink team for such an incredible product,” she wrote.
That growth rate reflects both rising demand for broadband in underserved regions and Starlink’s expanding satellite constellation, which now includes more than 9,000 low-Earth-orbit satellites designed to deliver high-speed, low-latency internet worldwide.
Starlink’s momentum
Starlink’s momentum has been building up. SpaceX reported 4.6 million Starlink customers in December 2024, followed by 7 million by August 2025, and 8 million customers in November. Independent data also suggests Starlink usage is rising sharply, with Cloudflare reporting that global web traffic from Starlink users more than doubled in 2025, as noted in an Insider report.
Starlink’s momentum is increasingly tied to SpaceX’s broader financial outlook. Elon Musk has said the satellite network is “by far” the company’s largest revenue driver, and reports suggest SpaceX may be positioning itself for an initial public offering as soon as next year, with valuations estimated as high as $1.5 trillion. Musk has also suggested in the past that Starlink could have its own IPO in the future.

NVIDIA Director of Robotics: Tesla FSD v14 is the first AI to pass the “Physical Turing Test”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine.
NVIDIA Director of Robotics Jim Fan has praised Tesla’s Full Self-Driving (Supervised) v14 as the first AI to pass what he described as a “Physical Turing Test.”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine. And just like smartphones today, removing it now would “actively hurt.”
Jim Fan’s hands-on FSD v14 impressions
Fan, a leading researcher in embodied AI who is currently solving Physical AI at NVIDIA and spearheading the company’s Project GR00T initiative, noted that he actually was late to the Tesla game. He was, however, one of the first to try out FSD v14.
“I was very late to own a Tesla but among the earliest to try out FSD v14. It’s perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn’t tell if a neural net or a human drove you home,” Fan wrote in a post on X.
Fan added: “Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.”
The Physical Turing Test
The original Turing Test was conceived by Alan Turing in 1950, and it was aimed at determining if a machine could exhibit behavior that is equivalent to or indistinguishable from a human. By focusing on text-based conversations, the original Turing Test set a high bar for natural language processing and machine learning.
This test has been passed by today’s large language models. However, the capability to converse in a humanlike manner is a completely different challenge from performing real-world problem-solving or physical interactions. Thus, Fan introduced the Physical Turing Test, which challenges AI systems to demonstrate intelligence through physical actions.
Based on Fan’s comments, Tesla has demonstrated these intelligent physical actions with FSD v14. Elon Musk agreed with the NVIDIA executive, stating in a post on X that with FSD v14, “you can sense the sentience maturing.” Musk also praised Tesla AI, calling it the best “real-world AI” today.

Tesla AI team burns the Christmas midnight oil by releasing FSD v14.2.2.1
The update was released just a day after FSD v14.2.2 started rolling out to customers.
Tesla is burning the midnight oil this Christmas, with the Tesla AI team quietly rolling out Full Self-Driving (Supervised) v14.2.2.1 just a day after FSD v14.2.2 started rolling out to customers.
Tesla owner shares insights on FSD v14.2.2.1
Longtime Tesla owner and FSD tester @BLKMDL3 shared some insights following several drives with FSD v14.2.2.1 in rainy Los Angeles conditions with standing water and faded lane lines. He reported zero steering hesitation or stutter, confident lane changes, and maneuvers executed with precision that evoked the performance of Tesla’s driverless Robotaxis in Austin.
Parking performance impressed, with most spots nailed perfectly, including tight, sharp turns, in single attempts without shaky steering. One minor offset happened only due to another vehicle that was parked over the line, which FSD accommodated by a few extra inches. In rain that typically erases road markings, FSD visualized lanes and turn lines better than humans, positioning itself flawlessly when entering new streets as well.
“Took it up a dark, wet, and twisty canyon road up and down the hill tonight and it went very well as to be expected. Stayed centered in the lane, kept speed well and gives a confidence inspiring steering feel where it handles these curvy roads better than the majority of human drivers,” the Tesla owner wrote in a post on X.
Tesla’s FSD v14.2.2 update
Just a day before FSD v14.2.2.1’s release, Tesla rolled out FSD v14.2.2, which was focused on smoother real-world performance, better obstacle awareness, and precise end-of-trip routing. According to the update’s release notes, FSD v14.2.2 upgrades the vision encoder neural network with higher resolution features, enhancing detection of emergency vehicles, road obstacles, and human gestures.
New Arrival Options also allowed users to select preferred drop-off styles, such as Parking Lot, Street, Driveway, Parking Garage, or Curbside, with the navigation pin automatically adjusting to the ideal spot. Other refinements include pulling over for emergency vehicles, real-time vision-based detours for blocked roads, improved gate and debris handling, and Speed Profiles for customized driving styles.
