The crew for SpaceX and Shift4’s all-civilian Inspiration4 mission is now complete. The final two members of the groundbreaking mission were announced on Tuesday at the Kennedy Space Center in Floria, where the Falcon 9 rocket carrying Inspiration4’s Crew Dragon capsule will be launching later this year.
Joining 38-year-old Shift4Payments CEO Jared Isaacman and 29-year-old physician assistant Hayley Arceneaux will be 41-year-old Chris Sembroski, an Air Force veteran and educator working for Lockheed Martin, and 51-year-old Dr. Sian Proctor, an entrepreneur, educator, and trained pilot who has a passion for space.
The final two crew members representing the #Inspiration4 mission pillars of Generosity and Prosperity have been named! Stay tuned to meet the full crew today at 10AM ET live on the Inspiration4 YouTube channel! https://t.co/K6Owk59wK9 pic.twitter.com/hSQbsuU6as

As per Inspiration4’s website, Sembroski will represent the virtue of Generosity, and Dr. Proctor will represent Prosperity. Isaacman represents the virtue of Leadership, while Arceneaux represents the virtue of Hope.
In an interview with TODAY‘s Tom Costello, Dr. Proctor remarked that being selected for the Inspiration4 mission felt like “opening up the chocolate bar and seeing the golden ticket to Willy Wonka and the chocolate factory.” She remarked that she had no worries about the mission at all, and that her reservations were actually more rooted in the prospect of the opportunity to go to space slipping by.
“I was more worried that this opportunity had slipped me by and I would never get the chance to go to space, but now here I am and that just shows you never give up because that moment for me is here… I’m ready. Just strap me in, let’s go!” she said.
As for Sembroski, launching from the Kennedy Space Center would be a rather symbolic experience. Twenty years ago, Sembroski showcased his passion for education and supporting passions by serving as a Space Camp counselor, an experience that he highlighted during his interview with TODAY.
And the last two crew members of Inspiration 4 are…

“I’ve taken that experience with me to really drive the passion for getting kids to seek their passion in science and technology and really spark the interest in those fields by using space as that medium, and then ever since it’s stuck with me,” he said.
Isaacson, for his part, remarked that he is extremely excited for the Inspiration4 launch. “This is a very real moment, but I can’t help but be overwhelmed just thinking about all of the history that came before us here. That’s what’s going through my mind, like the astronauts climbing into the Apollo missions and Skylab and the space shuttle. It’s just so incredible to be here,” he said.
The Inspiration4 crew would now be undergoing intensive training for their upcoming mission, which is expected to launch sometime this fall. Previously, Isaacson has noted that Inspiration4 could launch around October, but in his recent interview with the US media outlet, he noted that the mission could launch before the end of September instead. Such a timetable would give the crew just about six months to get fully trained and ready for a multi-day trip to space about 335 miles above Earth.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990
Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.
Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.
The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.
Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:
- Heated/Ventilated Front Seats with Powered Thigh Cushion
- Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
- Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
- Improved Airflow, Increased Efficiency, More Range
- 89 cubic feet of trunk space
- Upgraded Acoustic Glass and Suspension to Minimize Road Noise
- Adaptive Damping for a Smooth, Stable Ride
- Staggered Tires for Enhanced Grip
- Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
- 16″ First Row and 8″ Second Row Touchscreens
- 19-Speaker Immersive Tesla Audio
- 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
- FSD Supervised and Integrated Grok AI
Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:
- Door Trim Puddle Lights
- Suede Dashboard Wing
- Exterior and Interior Badging
- Floor Mats
- Sill Plates
The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.
Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

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.
The full interview with Lars Moravy is available below:
