Early on Saturday morning, SpaceX Crew Dragon ‘Endeavour’ (capsule C206) – carrying four international astronauts – flawlessly docked with the International Space Station (ISS) for the second time in less than a year.

Capping off a smooth 24 hours of free-flight following an equally successful Falcon 9 launch on Friday, April 23rd, Dragon’s third crewed space station arrival was captured in spectacular fashion – thanks in part to the presence of a separate Crew Dragon vehicle already docked to the orbiting outpost. Recently swapped between the two ISS docking ports capable of supporting Dragons, Crew-1 NASA astronaut Mike Hopkins had – by far – the best view in the house of Crew-2’s space station rendezvous while looking out the window of the other Crew Dragon on orbit.

Former NASA flight director and Space Shuttle program manager Wayne Hale put it best, stating that SpaceX “[made] it look easy” with a “perfectly successful [Crew-2] launch and docking” – the company’s third astronaut launch and space station rendezvous since May 2020.

After a mere three days of delays – one for weather – from an April 20th (4/20) target set almost three months earlier, Crew Dragon lifted off on SpaceX and NASA’s Crew-2 mission shortly before dawn on April 23rd. As the rocket rapidly carried Dragon and its passengers from sea level to dozens of kilometers above the Earth’s surface, it sailed into sunlight, producing a spectacle that stretched across a vast swath of the pre-dawn sky as the sun lit up Falcon 9’s second stage exhaust plume.

The four astronauts aboard the flight-proven Dragon were equally amazed as the inky black vacuum outside their spacecraft’s windows turned to blinding, unfiltered sunlight. One spectacle and a flawless trip into orbit on Falcon 9 behind them, French European Space Agency (ESA) astronaut Thomas Pesquet caught a glimpse of the rocket’s expended second stage effectively flying in formation a few miles below Crew Dragon.

After almost exactly 24 hours on its own and five major Draco thruster orbit-raising and trajectory-matching burns, as well as an unwelcome collision avoidance warning that ultimately turned out to be a false alarm, Crew Dragon capsule C206 completed its second space station docking without delay around 5am on April 24th. Pesquet has published several dozen excellent photos of the flight and docking, offering the best look yet at what life aboard a free-flying Dragon is really like for the four astronauts packed into a volume – as he himself notes – roughly equivalent to a large car’s cabin.

With its successful arrival, SpaceX – for the first time ever – had two separate Crew Dragon spacecraft docked to ISS simultaneously, marking the first of at least two more Dragon ‘hand-off’ milestones to come. Though NASA nominally planned to have Commercial Crew providers SpaceX and Boeing essentially take turns on operational astronaut ferry missions, the latter company’s Starliner spacecraft is more than a year and a half behind schedule and is unlikely to perform its first crewed demonstration flight before Q1 2022.

In other words, SpaceX has been forced to mature its Crew Dragon program much faster than expected to complete at least four back-to-back astronaut launches in ~17 months, while NASA is effectively dependent on the company to ensure the ISS remains fully crewed from May 2020 to sometime in 2022.

Following Crew-2’s smooth arrival, Crew-1’s Crew Dragon and its four-astronaut crew will return to Earth as early as April 28th. Sometime in October or November 2021, SpaceX will repeat that hand-off process once again when it launches Crew-3 and recovers Crew-2. There is a distant chance Boeing will have completed two successful test flights and be ready for Starliner’s operational astronaut launch debut in early 2022, but it’s arguably much more likely that SpaceX will also perform a third hand-off between Crew-3 and Crew-4 sometime in Q2 2022 before finally handing over the reins to Starliner.

Tesla’s northernmost Supercharger in North America opens

Published

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.

Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.

There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.

Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.

Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.

Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.

Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.

Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla hints toward Premium Robotaxi offering with Model S testing

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.

Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.

However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.

Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.

Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”

However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.

Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.

He said:

“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”

At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:

“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”

The Hardware

Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.

It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.

ACM3 specs include:

  • 1600 sparse INT8 TOPS (Trillion Operations Per Second).
  • The processing power of 5 billion pixels per second.
  • RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
  • RAP1 is enabled by an in-house developed AI compiler and platform software

As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”

More Details

Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.
