SpaceX Crew Dragon, four astronauts set for brief flight around the space station
To set the stage for another Dragon launch just a few weeks from now, NASA astronauts are preparing to board a SpaceX Crew Dragon for a brief flight around the International Space Station (ISS).
Orbiting roughly 400 km (250 mi) above the Earth’s surface, the ISS and its crew of seven international astronauts have just two docking ports available to manage a growing influx of SpaceX Crew and Cargo Dragon 2 spacecraft, as well as Boeing’s chronically delayed Starliner. While Starliner hasn’t flown since a near-catastrophic orbital debut in December 2019 and isn’t likely to reattempt that uncrewed flight test until the second half of 2021, SpaceX is in the exact opposite position as it prepares to sustain an unprecedented Dragon launch cadence.
One challenge of that cadence ramp – space station port logistics and availability – is now becoming clear as SpaceX nears its next Crew Dragon NASA astronaut launch.
All launched on SpaceX Cargo Dragons, including a third destroyed during Falcon 9’s CRS-7 launch failure, the International Space Station has just two perpendicular International Docking Adapter (IDA) ports – one facing space and the other facing Earth. Regardless of CRS-7’s lost port, that IDA duo was always NASA’s plan.
The ISS requires the use of a huge, robotic arm (Canadarm2) to unload unpressurized cargo from spacecraft and that arm doesn’t have the mobility to access vehicles docked to the Earth-facing IDA port, meaning that cargo spacecraft with IDA ports can really only dock on the space-facing port. Cargo Dragon 2’s use of IDA docking and the Cygnus spacecraft’s use of berthing thankfully mean that neither NASA Commercial Resupply Services 2 (CRS2) vehicle is at risk of a traffic jam.
Sierra Nevada Corporation (SNC) is set to debut the cargo variant of its Dream Chaser spaceplane as early as 2022 for annual launches and will need to share that same lone IDA port with Cargo Dragon for its (approximately) annual resupply missions. More importantly, though, Crew Dragon and Boeing’s Starliner both require the use of one of those two IDA ports to deliver astronauts to and from the ISS. Both spacecraft are also expected to leave with the same crew that launched on them, meaning that both will spend a fully six or so months in orbit on each crew rotation mission.
In general, NASA also plans to overlap all Commercial Crew Program (CCP) astronaut launches, meaning that Crew Dragon will wait for Starliner to arrive (and vice versa) before departing the ISS with its four-astronaut crew. Those use-cases and safety requirements combine to create strict, complex scheduling challenges that mean a Cargo Dragon or Dream Chaser can never be docked to the ISS during a crew handover, while also adding significant constraints to any planned private astronaut (tourist) missions to the station – of which SpaceX already has at least one.
In the meantime, though Boeing’s Starliner is now at least 18 months behind SpaceX’s Crew Dragon on the path to launching NASA astronauts to and from the ISS, SpaceX is picking up the slack to the extent that station ‘traffic’ conditions are practically unaffected. Whereas NASA’s nominal plan was to alternate between its two redundant Commercial Crew providers before Boeing ran into huge delays, SpaceX is on track to launch Crew Dragon’s Crew-2 astronaut ferry mission as early as April 22nd.
The flight-proven Demo-2 Dragon will then rendezvous with the ISS while Crew-1’s Dragon and four astronauts are still aboard the station. Crew-1 and Crew-2 will spend about a week together before the former group boards their Dragon and heads for home. As few as six or so weeks later, SpaceX could launch its second Cargo Dragon 2 resupply mission, known as CRS-22. – This morning’s “port relocation,” which will see the Crew-1 Dragon will ‘relocate’ from the station’s Earth-facing IDA to its space-facing port, is thus necessary to free up that port for Cargo Dragon’s arrival when Crew-1 departs.
Barring major delays, SpaceX is currently on track to complete another two Crew and Cargo Dragon launches in 2-3 months, marking four Dragon missions in seven months if all goes to plan. Another three Dragon missions are firmly scheduled in 2021, potentially making for seven Dragon launches in 11-12 months if schedules hold. SpaceX’s current record – technically achieved twice in 2018 and 2019 – is five orbital Dragon missions in 12 months.
Tune in below around 6am EDT (UTC-4) to catch Crew Dragon C207’s brief 46-minute jaunt around the International Space Station (ISS) – a first for an American crewed spacecraft of any kind.

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.”

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.
