SpaceX’s ninth Starlink launch gets a boost from first all-women weather crew
SpaceX’s second Starlink launch of the month is currently tracking towards a June 13th liftoff from Cape Canaveral, Florida.
In order for a rocket launch to get off the ground, however, a perfect mix of ingredients must come together. One of the most crucial ingredients is the weather. Behind the scenes, the U.S. Space Force’s 45th Weather Squadron of the 45th Space Wing Operations Group – based out of Patrick Air Force Base – works diligently to monitor and predict weather conditions leading up to and at the time of liftoff. Every rocket launch that lifts off from Kennedy Space Center or Cape Canaveral Air Force Station utilizes the weather monitoring services provided by the 45th Weather Squadron and SpaceX – the most prolific US launch company is – no different.
For SpaceX’s upcoming Starlink V1 L8 Rideshare Program mission, the entire weather team on console is female, a first in program history. The team is made up of six women all responsible for specific roles that must coordinate and work cohesively to monitor the weather and determine when it is safe to launch the Falcon 9.
The diverse team is comprised of military personnel and civilian weather officers. It is overseen by Maj Emily Graves, Launch Weather Commander, and orchestrated by Capt. Nancy Zimmerman, Launch Weather Director. A Lead Launch Weather Officer, Arlena Moses, coordinates information between the launch customer, SpaceX, and the 45th while three other members constantly monitor and decipher mountains of weather data.
Airman 1st class Hannah Mulcahey serves as Duty Forecaster and Jessica Williams serves as Radar Launch Weather Officer. Williams is responsible for monitoring information produced by a series of systems every three minutes. She monitors radar data for the amount of precipitation, clouds that are present in the area, and the thickness of the clouds among other things. This information is used to determine whether or not the rocket’s flight path is safe for the duration of the mission. Thick clouds can be an indicator of an unstable atmosphere capable of producing electricity – either naturally as cloud produced lightning or lightning produced by a rocket thrusting through the unstable atmosphere called triggered lightning.
Should radar information be too ambiguous or overexaggerated, the Reconnaissance Launch Weather Officer, Melody Lovin, coordinates the mission with a reconnaissance aircraft known as Weather One. For SpaceX’s upcoming launch, Weather One will only be activated if there is going to be bad weather present for launch, a small possibility if the launch date slips. Other launch customers such as NASA or United Launch Alliance will sometimes have Weather One in the air on standby throughout the duration of the countdown to launch dependent on mission constraints.
When Launch Weather Director, Capt Nancy Zimmerman, was asked during a media teleconference about how this historical assignment came about, she stated that it was pure coincidence. “It was happenstance. The flight commander of space lift, my supervisor, actually created a team, as he always does, and was like ‘Huh, this is actually an all-female team. Have we ever done this?’ And looking back through the database, you know, it hasn’t been done and he was like ‘Well, should we do this?’ and I said ‘Yes, let’s do it.’” Zimmerman said .
A primary factor enabling an all-female led launch weather team is simply that the workforce of the 45th Weather Squadron is now comprised of more females than ever before. According to Lovin, “We simply have more women on the team. Before we only had one and that was from the year 2000 to 2018 and 2018 came around and a lot of resident launch weather officers left and they also decided to expand the unit.” She went on to state that the massive uptick in launches from the Cape Canaveral Air Force Station and Kennedy Space Center was a driving factor of the weather unit expansion, “when they expanded the unit they hired three more women, so that means we have six women on the team.”
The personnel of the 45th Weather Squadron work day in and day out to monitor and forecast weather conditions ensuring safe air and space operation all year round. When it comes to rocket launches, watching the weather begins early and is done frequently. Weather patterns in central Florida can change rapidly causing a rocket launch attempt to be scrubbed completely, which is what occurred with SpaceX’s first attempt to launch NASA astronauts Bob Behnken and Doug Hurley to the International Space Station.
Understanding and tracking developing weather patterns of central Florida allows the 45th Weather Squadron to create launch mission execution forecasts that outline a possibility of violation (POV) of specific launch weather constraints ahead of a launch attempt and any planned backup attempts. These comprehensive forecasts cover everything from systems like frontal boundaries that influence area weather to the type of clouds expected at the time of launch. The forecasts are put together based on a series of ten Lightning Launch Commit Criteria rules and a series of user-defined constraint rules that are specific to each mission and launch vehicle such as SpaceX’s Falcon 9 or United Launch Alliance’s Atlas V for example.
The ten lightning launch commit criteria rules have been in place since the 1980s when an Atlas-Centaur rocket was ultimately lost due to triggered lightning. The rocket launched into a highly unstable and electrified atmosphere full of thick clouds creating the conditions necessary to trigger a lightning strike of the vehicle. It lost its navigation system and began to dangerously veer from its course. It was then destroyed in-flight by launch teams.
Given the high degree of uncertainty of Florida weather, a well-versed team of highly trained weather professionals is a necessary piece of the puzzle that is rocket launching. For the first time, that team is made up of incredibly inspiring females that undoubtedly will make the correct GO/NO GO call on launch day.
For SpaceX’s first Starlink SmallSat Rideshare Program mission, targeted to launch no earlier than (NET) Saturday, June 13 at 5:21 a.m. EDT (09:21 UTC), the 45th Weather Squadron team predicts a 30% chance of violation – meaning that weather is 70% GO for launch. The primary concern is a bank of cumulus clouds expected to be in the area. You can view the full launch mission execution forecast on the 45th Weather Squadron’s website.

Tesla finalizes AI5 chip design, Elon Musk makes bold claim on capability
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Tesla has finalized its chip design for AI5, as Elon Musk confirmed today that the new chip has reached the tape-out stage, the final step before mass production.
But in a brief reply on X, Musk clarified Tesla’s AI hardware roadmap, essentially confirming that the new chip will not be utilized for being “enough to achieve much better than human safety for FSD.”
He said that AI4 is enough to do that.
Instead, the AI5 chip will be focused on Tesla’s big-time projects for the future: Optimus and supercomputer clusters.
Musk thanked TSMC and Samsung for production support, noting that AI5 could become “one of the most produced AI chips ever.” Yet, the key pivot came in his direct answer: vehicles no longer need the bleeding-edge silicon.
And thank you to @TaiwanSemi_TSC and @Samsung for your support in bringing this chip to production! It will be one of most produced AI chips ever.

Existing AI4 hardware, which is already deployed in hundreds of thousands of HW4-equipped Teslas, delivers safety metrics superior to human drivers for Full Self-Driving. AI5 will instead accelerate Optimus robot development and massive Dojo-style training clusters.
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Now, with AI4 proving sufficient, the company avoids costly retrofits across its fleet while redirecting next-generation compute toward higher-value applications: dexterous robots and exponential training scale.
But is it reasonable to assume AI4 enables unsupervised self-driving? Yes, but with important caveats.
On the hardware side, the claim is credible. Tesla’s FSD stack runs end-to-end neural networks trained on billions of miles of real-world data. Internal safety data reportedly shows AI4-equipped vehicles already outperforming average human drivers by a significant margin in controlled metrics (collision avoidance, reaction time, edge-case handling).
Dual-redundant AI4 chips provide ample headroom for the driving task, leaving bandwidth for future model improvements without new silicon. Musk’s assertion aligns with Tesla’s pattern of over-provisioning compute early, then optimizing ruthlessly, exactly as HW3 once sufficed before HW4 scaled further.
Optimus and our supercomputer clusters.
AI4 is enough to achieve much better than human safety for FSD.

Unsupervised autonomy, meaning Level 4 or higher, is not solely a compute problem. Regulatory approval remains the primary gate.
Even if AI4 achieves “much better than human” safety statistically, agencies like the NHTSA demand exhaustive validation, liability frameworks, and public trust.
Tesla’s supervised FSD has shown rapid gains in recent versions, yet real-world edge cases, like construction zones, emergency vehicles, and adverse weather, still require driver intervention in many jurisdictions. Competitors like Waymo operate limited unsupervised fleets, but only in geofenced areas with extensive mapping. Tesla’s vision-only, fleet-scale approach is more ambitious—and harder to certify globally.
In short, Musk’s post is both pragmatic and bullish. AI4 is likely capable of unsupervised FSD from a technical standpoint. Whether regulators and consumers agree, and how quickly, will determine if Tesla’s bet pays off.
The company’s capital-efficient path keeps existing cars relevant while pouring future compute into robots. If the safety data holds, unsupervised autonomy could arrive sooner than many expect.

Elon Musk signals expansion of Tesla’s unique side business
Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
Elon Musk has signaled an expansion of Tesla’s unique side business, something that really has nothing to do with cars or spaceships, but fans of the company have truly adopted it as just another one of its awesome ventures.
Musk confirmed on Wednesday that Tesla would build a new Diner location in Palo Alto, Northern California. After hinting last October that it “probably makes sense to open one near our Giga Texas HQ in Austin and engineering HQ in Palo Alto,” it seems one of those locations is being set into motion.
Sure

Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
He first floated broader expansion plans shortly after the LA opening in July 2025, noting that if the prototype succeeded, Tesla would roll out similar venues in major cities worldwide and along long-distance Supercharger routes.
Earlier hints included a confirmed second site at Starbase in Texas, tied to SpaceX operations, underscoring the Diner’s role in enhancing Tesla’s ecosystem behind vehicles.
The Los Angeles location on Santa Monica Boulevard in West Hollywood has served as a high-profile test case. Opened in July 2025 at 7001 Santa Monica Blvd., it features the world’s largest urban Supercharging station with 80 V4 stalls open to all NACS-compatible EVs, over 250 dining seats, rooftop views, and 24/7 service.
The retro-futuristic building replaced a former Shakey’s and quickly became a destination. Tesla reported selling 50,000 burgers in the first 72 days—an average of over 700 daily—drawing crowds with Cybertruck-shaped packaging, breakfast extensions until 2 p.m., and movie screenings.
Palo Alto stands out as a logical next step for several reasons. As Tesla’s longstanding engineering headquarters in the heart of Silicon Valley, the city is home to thousands of Tesla employees, engineers, and executives who could benefit from a convenient, branded gathering spot.
The area boasts high EV adoption rates, dense tech talent, and heavy traffic along key corridors, making a large Supercharger-diner an ideal fit for both daily commuters and long-haul travelers.
Proximity to Stanford University and the innovation ecosystem would amplify its appeal, potentially serving as a showcase for Tesla’s vision of integrated mobility and lifestyle experiences. It could be a great way for Tesla to recruit new talent from one of the country’s best universities.
If Tesla and Musk decide to move forward with a Palo Alto diner, it would build directly on the LA prototype’s momentum while addressing Musk’s earlier calls for expansion near core Tesla hubs.
Whether it materializes as a full confirmation or evolves from these hints remains to be seen, but the pattern is clear: Tesla is testing ways to make charging stops memorable. For EV drivers and enthusiasts alike, a Silicon Valley outpost could blend cutting-edge tech with nostalgic comfort, further embedding Tesla into everyday culture. As Musk’s comments suggest, the future of the Diner looks promising.

The Starship V3 static fire everyone was waiting for just happened
SpaceX completed a full duration of Starship V3 today clearing the path for Flight 12.
SpaceX is that much closer to launching their next-gen Starship after completing today’s full duration static fire out of Starbase, Texas. This marks a direct signal that Flight 12, the maiden voyage of Starship V3, is imminent. SpaceX confirmed the test on X, posting that the full duration firing was completed ahead of the vehicle’s next flight test.
The road to today started on March 16, when Booster 19 completed a shorter 10-engine static fire, also at the newly constructed Pad 2. That test ended early due to a ground systems issue but confirmed all installed Raptor 3 engines started cleanly. Booster 19 returned to the Mega Bay, received its remaining 23 engines for a full complement of 33, and rolled back out this week for the complete test campaign. Musk confirmed earlier this month that Flight 12 is now 4 to 6 weeks away.
Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
The numbers behind the world’s most powerful rocket are genuinely hard to put in context. Each Raptor 3 engine produces roughly 280 tons of thrust, and with all 33 firing simultaneously from the super heavy booster, this generates approximately 9,240 tons of combined thrust, more than any rocket in history. For context, that’s enough thrust to lift the entire Empire State Building, and then some. V3 stands 408 feet tall and can carry over 100 tons to low Earth orbit in a fully reusable configuration. The V2 generation topped out at around 35 tons.
Historically, a successful full-duration static fire is the last major ground milestone before launch. SpaceX has followed this pattern with every Starship iteration since the program began in 2023. Musk has been direct about the ambition behind all of it. “I am highly confident that the V3 design will achieve full reusability,” he wrote on X earlier this year. Full reusability of both stages is the foundation of SpaceX’s plan to make regular flights to the Moon and Mars economically viable. Today’s test brings that goal one significant step closer.
Starship V3 delivers on two most critical promises of full reusability and in-orbit refueling. The reusability case is straightforward, and one we have seen with Falcon 9 wherein the rocket can fly again within a day rather than building a new one for every mission. It’s the only economic model that makes frequent lunar cargo runs viable. The in-orbit refueling piece is less obvious but equally essential. To reach the Moon with enough payload, Starship requires roughly ten dedicated tanker flights to fuel up a propellant depot in low Earth orbit before it can even begin its journey to the lunar surface. That capability has never been demonstrated at scale, and Flight 12 is the first step toward proving it works. As Teslarati reported, NASA’s Artemis II crew completed a historic lunar flyby earlier this month, the first humans to travel beyond low Earth orbit since 1972, but getting astronauts to actually land and eventually supply a permanent Moon base requires a cargo pipeline that only a fully reusable, refuelable Starship V3 can deliver at the volume and cost NASA’s plans demand.
