SpaceX preparing for back-to-back Starlink launches from California and Florida
Update: Next Spaceflight reports that SpaceX has delayed Starlink 4-15 to 4:38 pm EDT, May 14th, ending the immediate possibility of a new SpaceX record for time between launches.
After a few days of delays pushed the missions closer together, SpaceX is now preparing to launch two batches of 53 Starlink satellites just eight hours apart – one from Florida and the other from California.
Originally scheduled to launch as early May 10th, which would have tied SpaceX’s Vandenberg Space Force Base (VSFB) SLC-4E launch pad turnaround record, Starlink 4-13 slipped to May 12th within the last few days. 2400 miles (~3900 km) to the east, SpaceX’s Starlink 4-15 mission – preparing to launch from the company’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad – recently found itself in the opposite boat.
On April 22nd, Spaceflight Now reported that Starlink 4-15 was scheduled to launch no earlier than (NET) May 8th. At the time, Starlink 4-13 was also scheduled to launch on the 8th, placing the two Starlink missions just a few hours apart. On April 28th, Spaceflight Now updated its well-sourced launch calendar, revealing that Starlink 4-13 had slipped to May 10th and Starlink 4-15 to May 16th, ending their concurrence. Finally, on May 7th and May 8th, photographer Ben Cooper reported that Starlink 4-15 had moved up to 2:08 am EDT (06:08 UTC), May 13th and FAA documents revealed that Starlink 4-13 had slipped again to 3:29 pm PDT (22:29 UTC), May 12th.
In other words, the missions have again found themselves just a handful of hours apart after weeks of unrelated juggling and delays. Barring additional issues, Starlink 4-13 and Starlink 4-15 are scheduled to launch just 7 hours and 41 minutes apart. Set in late 2021, the shortest time between two Falcon launches is currently 15 hours and 17 minutes. But above all else, the constant back and forth – only to end up with both launches again just hours apart – demonstrates just how agonizing and unforgiving the planning behind every rocket launch schedule truly is.
Fittingly, Starlink 4-13’s drone ship headed to sea just ~60 hours before the scheduled launch and Starlink 4-15’s drone ship has yet to depart, keeping the launch dates of both missions about as uncertain as they can be without guaranteeing that delays are coming. Both drone ships must be towed about 400 miles downrange at speeds that almost never exceed 8-10 mph, translating to a minimum two-day journey even with zero stops, slowdowns, or detours.
Beyond the record-breaking potential, Starlink 4-13 is an otherwise ordinary mission that will launch another 53 Starlink V1.5 satellites to an ordinary 53.2-degree inclination, which simply means that they’ll end up in the same ‘shell’ as the other satellites in Starlink’s ‘Group 4’ shell. Despite launching from the opposite coast of the US, Starlink 4-15 will be almost identical and is expected to deploy another 53 Starlink V1.5 satellites to the same orbital shell. However, it appears that Starlink 4-15 will have a few highly unusual features.
Instead of performing a hockey stick-like ‘dogleg’ maneuver to avoid overflying any populated islands in the Bahamas, Falcon 9 will directly overfly the country’s largest western island and attempt to land right in the middle of the archipelago, potentially touching down on a drone ship just 5-15 miles away from Nassau and a couple other islands. The fact alone that SpaceX was able to convince both the Bahamas and the US’ FAA to allow it to fly the trajectory shown above is extremely impressive and belies a deep trust in SpaceX’s expertise and Falcon 9’s safety and reliability. At the same time, SpaceX may be taking some degree of risk, as the trajectory’s minuscule margins for error probably mean that Falcon 9’s automatic flight termination system will be programmed to destroy the rocket at the slightest hint of deviation from the planned trajectory.
Adding to the oddity, Starlink 4-15 will be the first in a long line of 45 dedicated Starlink launches to debut a new Falcon 9 booster. According to Next Spaceflight, Falcon 9 B1073 will claim that unusual first, almost entirely flipping the table on the precedent of conservative government customers – still timid about SpaceX reusability – scrambling to secure increasingly rare launch opportunities on new Falcon 9 boosters. Alternatively, it’s possible – but unlikely – that SpaceX implemented significant changes to Falcon 9 B1073 that it wants to verify independently before risking customer payloads.
With any luck, the new rocket will perform flawlessly and give some nearby Bahamians a truly one-of-a-kind experience: the ability to watch a SpaceX Falcon 9 booster land at sea… from the comfort of their own homes.

Elon Musk and Tesla AI Director share insights after empty driver seat Robotaxi rides
The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.
Tesla CEO Elon Musk and AI Director Ashok Elluswamy celebrated Christmas Eve by sharing personal experiences with Robotaxi vehicles that had no safety monitor or occupant in the driver’s seat. Musk described the system’s “perfect driving” around Austin, while Elluswamy posted video from the back seat, calling it “an amazing experience.”
The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.
Elon and Ashok’s firsthand Robotaxi insights
Prior to Musk and the Tesla AI Director’s posts, sightings of unmanned Teslas navigating public roads were widely shared on social media. One such vehicle was spotted in Austin, Texas, which Elon Musk acknowleged by stating that “Testing is underway with no occupants in the car.”
Based on his Christmas Eve post, Musk seemed to have tested an unmanned Tesla himself. “A Tesla with no safety monitor in the car and me sitting in the passenger seat took me all around Austin on Sunday with perfect driving,” Musk wrote in his post.
Elluswamy responded with a 2-minute video showing himself in the rear of an unmanned Tesla. The video featured the vehicle’s empty front seats, as well as its smooth handling through real-world traffic. He captioned his video with the words, “It’s an amazing experience!”
Towards Unsupervised operations
During an xAI Hackathon earlier this month, Elon Musk mentioned that Tesla owed be removing Safety Monitors from its Robotaxis in Austin in just three weeks. “Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks,” he said. Musk echoed similar estimates at the 2025 Annual Shareholder Meeting and the Q3 2025 earnings call.
Considering the insights that were posted Musk and Elluswamy, it does appear that Tesla is working hard towards operating its Robotaxis with no safety monitors. This is quite impressive considering that the service was launched just earlier this year.

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.
