SpaceX to upgrade Dragon with the most immersive window ever launched into space

SpaceX and Inspiration4 customer Jared Isaacman have revealed a substantial and unexpected design change made to the Crew Dragon spacecraft that will carry the billionaire and three guests into orbit later this year.

Reminiscent of the beloved “Cupola” (Italian for dome) built by the European Space Agency (ESA) and installed on the International Space Station (ISS) in 2010, SpaceX says it has designed a spectacular ‘glass dome’ window add-on for Crew Dragon. Thanks to some level of newfound commercial interest in free-flying Crew Dragon missions, in which the spacecraft would operate as its own miniature space station for several days, SpaceX concluded that it could fully remove the spacecraft’s docking adapter.

In its place, SpaceX has apparently designed a huge, monolithic, dome-like window that promises to offer a viewing experience likely unmatched in the history of spaceflight.

While the ISS Cupola is reminiscent of Crew Dragon’s glass dome, the two windows are only similar in the sense that they’re both space-based viewing windows. Beyond that, the Dragon Dome is more akin to the ultimate realization of the platonic ideal that ESA engineers tried to achieve with the Cupola. Featuring an approximate 2:1 ratio of framework and structural support material to glass, the Cupola’s central circular window has an uninterrupted diameter of 80 cm (2.6 ft), while the whole assembly has a total internal diameter of ~2m (6.6 ft) and a depth (the ‘height’ of the conical windowed area) of about 50 cm (1.6 ft).

Assuming SpaceX is explicitly designing the dome to integrate with Crew Dragon’s existing International Docking Adapter (IDA) support structure, it could have a diameter as large as 1.4m (~4.5 ft) and a depth of 60 cm (~2 ft; assuming a perfect hemisphere for maximum strength). If SpaceX’s official render is correct, the dome will also be monolithic, meaning that the glass window itself would be completely uninterrupted by structural supports.

Assuming a semi-modular design, a Dragon’s ‘dome’ would likely be installed where the innermost red ring (a vacuum seal) is located – a diameter of 1.3-1.4m (4.3-4.6 ft). The ISS Cupola’s total internal diameter is about the same as the larger red nosecone seal. (NASA)

Much like the Cupola, which has foldable ‘petals’ that serve as shades and micrometeorite shields when the module isn’t in use, Crew Dragon’s glass dome would be safely enclosed inside the spacecraft’s nosecone. It’s unclear what material the dome would be made out of, given that large, monolithic, bulletproof domes are a technology that effectively does not exist. At least one company, Surmet, specializes in manufacturing aluminum oxynitride (“transparent aluminum”) windows, including small domes for things like missile sensor pods.

However, the maximum size of those commercial ALON domes is roughly half a foot in diameter and there is no evidence that anyone has attempted the produce an ALON dome even a full magnitude smaller than what SpaceX’s Dragon window would require. This is to say that if SpaceX has found a way to produce massive monolithic windows and domes rated for space travel, it will effectively leap from a total outsider to a de facto leader of the niche bulletproof glass dome industry. It’s worth noting that CEO Elon Musk has stated that Tesla’s Cybertruck will feature “transparent metal” windows, which would likely make the EV company the world leader in ALON window mass-production – expertise that SpaceX could borrow from given their history of joint materials R&D.

In a live March 30th event celebrating the final crew selection, SpaceX director Benji Reed stated that NASA has been closely involved with with development of Dragon’s dome window. Most notably, he strongly implied that flight-proven Crew Dragons would be able to swap between dome and docking hardware with enough ease that a Dragon flown with a dome on a SpaceX tourist mission could still be modified to support NASA astronaut launches, thus ensuring commonality within the Dragon ‘fleet’ SpaceX is building.

SpaceX has implied that its Dragon Dome will debut as early as September 2021 on billionaire Jared Isaacman’s Inspiration4 mission – currently on track to become the world’s first fully private astronaut launch.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent

Published

on

Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.

Tesla reported it delivered 467,762  Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.

Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.

For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.

Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

Tesla sends production Cybercab with no steering wheel, pedals to on-road testing

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.

Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.
