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 exec pleads for federal framework of autonomy to U.S. Senate Committee

Tesla executive Lars Moravy appeared today in front of the U.S. Senate Commerce Committee to highlight the importance of modernizing autonomy standards by establishing a federal framework that would reward innovation and keep the country on pace with foreign rivals.

Moravy, who is Tesla’s Vice President of Vehicle Engineering, strongly advocated for Congress to enact a national framework for autonomous vehicle development and deployment, replacing the current patchwork of state-by-state rules.

These rules have slowed progress and kept companies fighting tooth-and-nail with local legislators to operate self-driving projects in controlled areas.

Tesla already has a complete Robotaxi model, and it doesn’t depend on passenger count

Moravy said the new federal framework was essential for the U.S. to “maintain its position in global technological development and grow its advanced manufacturing capabilities.

He also said in a warning to the committee that outdated regulations and approval processes would “inhibit the industry’s ability to innovate,” which could potentially lead to falling behind China.

Being part of the company leading the charge in terms of autonomous vehicle development in the U.S., Moravy highlighted Tesla’s prowess through the development of the Full Self-Driving platform. Tesla vehicles with FSD engaged average 5.1 million miles before a major collision, which outpaces that of the human driver average of roughly 699,000 miles.

Moravy also highlighted the widely cited NHTSA statistic that states that roughly 94 percent of crashes stem from human error, positioning autonomous vehicles as a path to dramatically reduce fatalities and injuries.

Skeptics sometimes point to cybersecurity concerns within self-driving vehicles, which was something that was highlighted during the Senate Commerce Committee hearing, but Moravy said, “No one has ever been able to take over control of our vehicles.”

This level of security is thanks to a core-embedded central layer, which is inaccessible from external connections. Additionally, Tesla utilizes a dual cryptographic signature from two separate individuals, keeping security high.

Moravy also dove into Tesla’s commitment to inclusive mobility by stating, “We are committed with our future products and Robotaxis to provide accessible transportation to everyone.” This has been a major point of optimism for AVs because it could help the disabled, physically incapable, the elderly, and the blind have consistent transportation.

Overall, Moravy’s testimony blended urgency about geopolitical competition, especially China, with concrete safety statistics and a vision of the advantages autonomy could bring for everyone, not only in the U.S., but around the world, as well.

Tesla Model Y lineup expansion signals an uncomfortable reality for consumers

Published

Tesla launched a new configuration of the Model Y this week, bringing more complexity to its lineup of the vehicle and adding a new, lower entry point for those who require an All-Wheel-Drive car.

However, the broadening of the Model Y lineup in the United States could signal a somewhat uncomfortable reality for Tesla fans and car buyers, who have been vocal about their desire for a larger, full-size SUV.

Tesla has essentially moved in the opposite direction through its closure of the Model X and its continuing expansion of a vehicle that fits the bill for many, but not all.

Tesla brings closure to Model Y moniker with launch of new trim level

While CEO Elon Musk has said that there is the potential for the Model Y L, a longer wheelbase configuration of the vehicle, to enter the U.S. market late this year, it is not a guarantee.

Instead, Tesla has prioritized the need to develop vehicles and trim levels that cater to the future rollout of the Robotaxi ride-hailing service and a fully autonomous future.

But the company could be missing out on a massive opportunity, as SUVs are a widely popular body style in the U.S., especially for families, as the tighter confines of compact SUVs do not support the needs of a large family.

Although there are other companies out there that manufacture this body style, many are interested in sticking with Tesla because of the excellent self-driving platform, expansive charging infrastructure, and software performance the vehicles offer.

Additionally, the lack of variety from an aesthetic and feature standpoint has caused a bit of monotony throughout the Model Y lineup. Although Premium options are available, those three configurations only differ in terms of range and performance, at least for the most part, and the differences are not substantial.

Minor Expansions of the Model Y Fail to Address Family Needs for Space

Offering similar trim levels with slight differences to cater to each consumer’s needs is important. However, these vehicles keep a constant: cargo space and seating capacity.

Larger families need something that would compete with vehicles like the Chevrolet Tahoe, Ford Expedition, or Cadillac Escalade, and while the Model X was its largest offering, that is going away.

Tesla could fix this issue partially with the rollout of the Model Y L in the U.S., but only if it plans to continue offering various Model Y vehicles and expanding on its offerings with that car specifically. There have been hints toward a Cyber-inspired SUV in the past, but those hints do not seem to be a drastic focus of the company, given its autonomy mission.

Tesla appears to be mulling a Cyber SUV design

Model Y Expansion Doesn’t Boost Performance, Value, or Space

You can throw all the different badges, powertrains, and range ratings on the same vehicle, it does not mean it’s going to sell better. The Model Y was already the best-selling vehicle in the world on several occasions. Adding more configurations seems to be milking it.

The true need of people, especially now that the Model X is going away, is going to be space. What vehicle fits the bill of a growing family, or one that has already outgrown the Model Y?

Not Expanding the Lineup with a New Vehicle Could Be a Missed Opportunity

The U.S. is the world’s largest market for three-row SUVs, yet Tesla’s focus on tweaking the existing Model Y ignores this. This could potentially result in the Osborne Effect, as sales of current models without capturing new customers who need more seating and versatility.

Expansions of the current Model Y offerings risk adding production complexity without addressing core demands, and given that the Model Y L is already being produced in China, it seems like it would be a reasonable decision to build a similar line in Texas.

Listening to consumers means introducing either the Model Y L here, or bringing a new, modern design to the lineup in the form of a full-size SUV.

Elon Musk recently reiterated one of the most ambitious forecasts for Tesla’s humanoid robot, Optimus, stating it could become the first real-world example of a Von Neumann machine. He also noted once more that Optimus would be Tesla’s biggest product.

Musk shared his comments in a series of posts on social media platform X.

Optimus as a von Neumann machine

In response to a post on X that pondered on sci-fi timelines becoming real, Musk wrote that “Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet.” In a separate post, Musk wrote that Optimus will be Tesla’s “biggest product ever,” a phrase he has used in the past to describe the humanoid robot’s importance to the electric vehicle maker.

A Von Neumann machine is a class of theoretical self-replicating systems originally proposed in the mid-20th century by the mathematician John von Neumann. In his concept, von Neumann described machines that could travel to other worlds, use local materials to create copies of themselves, and carry out large-scale tasks without outside intervention.

Elon Musk’s broader plans

Considering Musk’s comments, it appears that Optimus would eventually be capable of performing complex work autonomously in environments beyond Earth. If Optimus could achieve such a feat, it could very well unlock humanity’s capability to explore locations beyond Earth. The idea of space exploration becomes more than feasible.

Elon Musk has discussed space-based AI compute, large-scale robotic production, and the role of SpaceX’s Starship in transporting hardware and materials to other planets. While Musk did not detail how Optimus would fit with SpaceX’s exploration activities, his Von Neumann machine comments suggest he is looking at Tesla’s robotics as part of a potential interplanetary ecosystem.
