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 ships out update that brings massive change to two big features
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
Tesla has shipped out an update for its vehicles that was caused specifically by a California lawsuit that threatened the company’s ability to sell cars because of how it named its driver assistance suite.
Tesla shipped out Software Update 2026.2.9 starting last week; we received it already, and it only brings a few minor changes, mostly related to how things are referenced.
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
The following changes came to Tesla vehicles in the update:
- Navigate on Autopilot has now been renamed to Navigate on Autosteer
- FSD Computer has been renamed to AI Computer
Tesla faced a 30-day sales suspension in California after the state’s Department of Motor Vehicles stated the company had to come into compliance regarding the marketing of its automated driving features.
The agency confirmed on February 18 that it had taken a “corrective action” to resolve the issue. That corrective action was renaming certain parts of its ADAS.
Tesla discontinued its standalone Autopilot offering in January and ramped up the marketing of Full Self-Driving Supervised. Tesla had said on X that the issue with naming “was a ‘consumer protection’ order about the use of the term ‘Autopilot’ in a case where not one single customer came forward to say there’s a problem.”
This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.

It is now compliant with the wishes of the California DMV, and we’re all dealing with it now.
This was the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” names. Previous Transportation Secretary Pete Buttigieg was one of those federal-level employees who had an issue with the names “Autopilot” and “Full Self-Driving.”
Tesla sued the California DMV over the ruling last week.

Tesla workers push back against Giga Berlin unionization
“IG Metall did not succeed in Giga Berlin‘s works council election earlier today. The union share was reduced from nearly 40% in 2024 to 31% in 2026! This is a clear message by the Giga Berlin team towards an independent co-determination! The list called Giga United, led by the current chairwoman, Michaela Schmitz, received the most votes with more than 40%! Good news for Giga Berlin!”
Tesla workers pushed back against unionization efforts at Gigafactory Berlin, and over the past few years, there has been a dramatic decrease in interest to unionize at the German plant.
Gigafactory Berlin Plant Manager André Thierig announced on Wednesday that IG Metall, the European union group, saw its share reduce from 40 to 31 percent in 2026 as employees eligible to vote on the issue. Instead, the Giga Berlin team, known as Giga United, received the most votes with more than 40 percent.

Thierig gave specific details in a post on X:
“IG Metall did not succeed in Giga Berlin‘s works council election earlier today. The union share was reduced from nearly 40% in 2024 to 31% in 2026! This is a clear message by the Giga Berlin team towards an independent co-determination! The list called Giga United, led by the current chairwoman, Michaela Schmitz, received the most votes with more than 40%! Good news for Giga Berlin!”
There were over 10,700 total employees who were eligible to vote, with 87 percent of them turning out to cast what they wanted. There were three key outcomes: Giga United, IG Metall, and other notable groups, with the most popular being the Polish Initiative.
The 37-seat council remains dominated by non-unionized representatives, preserving Giga Berlin as Germany’s only major auto plant without a collective bargaining agreement.
Thierig and Tesla framed the outcome as employee support for an “independent, flexible, and unbureaucratic” future, enabling acceleration on projects like potential expansions or new models. IG Metall expressed disappointment, accusing management of intimidation tactics and an “unfair” campaign.
The first election of this nature happened back in 2022. In 2024, IG Metall emerged as the largest single faction with 39.4 percent, but non-union lists coalesced for a majority.
But this year was different. There was some extra tension at Giga Berlin this year, as just two weeks ago, an IG Metall rep was accused by Tesla of secretly recording a council meeting. The group countersued for defamation.

This result from the 2026 vote reinforced Tesla’s model of direct employee-management alignment over traditional German union structures, amid ongoing debates about working conditions. IG Metall views it as a setback but continues advocacy. Tesla sees it as validation of its approach in a competitive EV market.
This outcome may influence future labor dynamics at Giga Berlin, including any revival of expansion plans or product lines, which Musk has talked about recently.

SpaceX President Gwynne Shotwell details xAI power pledge at White House event
The commitment was announced during an event with United States President Donald Trump.
SpaceX President Gwynne Shotwell stated that xAI will develop 1.2 gigawatts of power at its Memphis-area AI supercomputer site as part of the White House’s new “Ratepayer Protection Pledge.”
The commitment was announced during an event with United States President Donald Trump.
During the White House event, Shotwell stated that xAI’s AI data center near Memphis would include a major energy installation designed to support the facility’s power needs.
“As you know, xAI builds huge supercomputers and data centers and we build them fast. Currently, we’re building one on the Tennessee-Mississippi state line. As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors…
“xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
She added that the system would provide significant backup power capacity.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”
Shotwell also noted that xAI will be supporting the area’s water supply as well.
“We haven’t talked about it yet, but this is actually quite important. We will build state-of-the-art water recycling plants that will protect approximately 4.7 billion gallons of water from the Memphis aquifer each year. And we will employ thousands of American workers from around the city of Memphis on both sides of the TN-MS border,” she noted.
The Ratepayer Protection Pledge was introduced as part of the federal government’s effort to address concerns about rising electricity costs tied to large AI data centers, as noted in an Insider report. Under the agreement, companies developing major AI infrastructure projects committed to covering their own power generation needs and avoiding additional costs for local ratepayers.
