SpaceX Inspiration4 astronaut shares behind-the-scenes look at largest space window’s ‘first light’
SpaceX Inspiration4 astronaut Sian Proctor has shared the first behind-the-scenes look at what it was like for the world’s first all-private astronaut crew to witness the largest window ever flown in space for the first time.
In front of the camera: Hayley Arceneaux, now the youngest American astronaut in history and the first person ever to fly in space (or orbit) with an internal prosthetic. The mission: Inspiration4, a philanthropic creation of billionaire and CEO Jared Isaacman heavily focused on raising money (and awareness) for St. Jude’s Children’s Hospital and the fight against childhood cancer. While, as many an internet-goer will be more than eager to point out, Isaacman could have technically donated ~10% – not ~5% – of his net worth and been done with it, he instead decided to commit $100M to St. Jude’s and shepherd the world’s first all-private crewed orbital spaceflight into existence.
Private orbital spaceflight is not unique – seven other paying customers have flown to orbit and back in the 21st century. What Jared conceived of, however, is. Instead of a rather less inspirational mishmash of anyone rich enough to pay ~$20-40M for a seat, Isaacman chose to invite three relatively ordinary people along for the ride and even raffled one of the three ‘tickets’ to any American willing to donate $10 or more to the fight against childhood cancer. A step further, thanks to an excellent and transparent social media presence, millions of people from around the world got to follow the mission’s progress, watch a large portion of it live, and generally be awed by an important step forward for spaceflight and inspired by one of the most simultaneously eclectic and ordinary astronaut crew of all time.
More to the point, millions of people (or at least hundreds of thousands, for now) wouldn’t have gotten to vicariously experience the sheer joy of the first orbital cancer survivor experiencing the largest, most uninterrupted window ever flown in space for the first time. Officially known as the ‘cupola,’ SpaceX conceived of, designed, built, qualified, and flew the massive dome window in less than a year from start to finish.
Measuring around 1.2m (3.9 ft) wide and around 0.8-1m (2.5-3.2 ft) wide on the inside, Inspiration4’s cupola might offer less internal volume than NASA’s decade-old International Space Station cupola, but it makes up for the tighter space with the largest seamless window ever flown in space. Likely made out of several layers of acrylic domes not dissimilar to the ‘bubbles’ one might come across at aquariums, the innermost ‘layer’ of Dragon’s cupola carries an odd brownish hue but the glass (technically plastic) is still almost completely transparent and has no ‘frame’ or interruptions save for where it attaches to the spacecraft itself.
Thankfully, by all appearances, that brownish hue – perhaps some kind of optical coating or a tint to reduce glare – isn’t easily discernable from the inside looking out. Instead, the uninterrupted window practically melts away into a crystal-clear nothing, offering what has to be one of the best views available in space.
Given that SpaceX reportedly turned Dragon’s cupola from idea to reality in the matter of a single year and for a single customer, it’s difficult to imagine what additional upgrades could be realized on future Dragon spacecraft. Already, a senior SpaceX director says that the company is seriously considering building one or several new Dragons solely for private astronaut launches after receiving a massive uptick in demand for tickets to orbit. Even before Inspiration4 had splashed down, CEO Elon Musk promised that future flights would offer in-flight internet and hot food with the addition of a small oven/heater and a connection to the company’s own Starlink satellite constellation.
If SpaceX were to build an entirely new Dragon just for private free-flyer launches, it could potentially implement significant design changes as long as they didn’t appreciably lower safety. Given that an exclusively free-flying Dragon would never need to worry about docking in orbit, SpaceX might even be able to tweak the nosecone and make the cupola wider and taller. The possibilities may be far from endless but the fact that SpaceX would consider a modification as extreme as the cupola that flew on Inspiration4 in the first place suggests that the company is quite a lot more confident – and more willing to make big changes – than one might have previously guessed.

Tesla deploys Unsupervised FSD in Europe for the first time—with a twist
Europe has so far been elusive for Tesla’s FSD rollout.
Tesla has officially started using Unsupervised FSD in Europe, at least, within the Giga Berlin complex.
Ready for rollout
As per a video from the Tesla AI team, Model Y units that are produced at Giga Berlin now autonomously transport themselves from the end of the production line to their designated holding areas. The video demonstration, which was posted on X, followed a Model Y unit that parked itself autonomously at a charging station, and another that headed straight to Giga Berlin’s outbound area.
Giga Berlin plant manager André Thierig shared his insights on the video, stating that “Every Tesla we built has the ability to drive autonomously and we use this feature 100% for outbound operations, starting from the light tunnel until the car arrives at the outbound yard! Really impressive!” He also stated that he “cannot wait to see this on European roads outside the factory.”
Unsupervised FSD in Europe
Europe has so far been elusive for Tesla’s FSD rollout. While FSD Supervised has been rolled out to consumers in the United States, and to some degree, in China, only tests have so far been implemented in Europe. This has resulted in numerous Tesla owners getting their patience tested, especially those who have purchased FSD in vehicles that are now several years old.
Tesla, for its part, has been demonstrating Unsupervised FSD operating on public European roads across several countries, such as France and Germany. So far, however, the wait is still on for Europe to allow FSD, both Supervised and Unsupervised, to be operated by regular consumers on public roads.

Tesla Robotaxi makes major expansion with official public app launch
Tesla officially announced on early Thursday morning that its Robotaxi suite is officially public, launching its separate Robotaxi app to iOS users for the first time, allowing them to test out the driverless ride-hailing platform.
Tesla has made a major expansion with its Robotaxi platform, marking its official public launch of the app for iOS users.
Tesla has had an active Robotaxi program for two and a half months now, launching it for the first time in Austin, Texas, in late June.
It was not a public beta, as the company extended invitations to a select group of relevant influencers and media in the space, aiming to keep things relatively private until confidence in its performance was established.
Over the past ten weeks, Tesla has expanded its fleet size, its geofence, and its list of invitees on several occasions. However, it was still not offering rides to anyone on the street. That has changed.
Tesla officially announced on early Thursday morning that its Robotaxi suite is officially public, launching its separate Robotaxi app to iOS users for the first time, allowing them to test out the driverless ride-hailing platform:

Once you download the app, you will be put on a waitlist to enter the company’s list of riders. It seems that the earlier you download and join, the sooner you will be able to test one of the company’s driverless Model Y vehicles in the city.
The expansion of the app marks a major achievement for Tesla in the sense that the company is confident to begin allowing more riders to utilize the platform. It may also be looking for a more local consumer base, as many users of the app do not reside in Austin. Tesla may hope to attract more daily users who would utilize Robotaxi for their commute to work, rides to dinner and social events, and other regular uses.
In its nearly three months of operation, Tesla has expanded the Robotaxi geofence in Austin on three occasions, with the most recent bringing the Service Area to 190 square miles.
Tesla Robotaxi geofence expansion enters Plaid Mode and includes a surprise
The most recent growth included new territories, including Giga Texas, the company’s manufacturing facility, Austin-Bergstrom International Airport, and freeway driving for the first time.
Freeways are where Tesla has taken a slightly different approach, as it will be moving the safety monitor to the driver’s seat for those trips for the time being.

It appears that there are several big changes to this next-generation version of Optimus, some of which have been discussed by Musk and Tesla in the past.
The first is purely cosmetic, but the gold color that Optimus is wearing in this is a new and fresh look that we have not seen before.
Perhaps the most interesting change that is evident here is the hands, which are much more detailed than past versions of Optimus:
However, we’re not too sure that these are what will be released with the next-gen Optimus, because they don’t appear to be functional, and they are more reminiscent of mannequin hands than anything.
The hands on Optimus have been a significant part of the program, as they are among the most crucial pieces of equipment on a robot. It needs to be able to perform both delicate and more imposing tasks. Tesla has aimed for Optimus to be able to thread needles or play the piano.
It was one of the most discussed improvements the company mentioned in past comments regarding how it planned to improve from Gen 2 to this next version.
Musk mentioned regarding Optimus:
“Next-generation Optimus hand, which we have in prototype form, has actuators that have moved to the forearm, just like humans, and they operate the fingers through cables, just like human hands.”
Within Optimus lies a significant opportunity for Tesla to gain considerable strength in terms of market share and valuation.
If Tesla can efficiently develop and deploy the humanoid robot over the next several years, the company stands to gain, as companies will utilize it for tasks that require tedious labor.
Musk recently said Optimus will be a major contributor to Tesla’s valuation moving forward. He believes it will make up roughly 80 percent of the company’s value.
