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’s Semi truck factory is open with a detail that changes everything
Tesla’s dedicated Nevada Semi factory has opened, targeting 50,000 trucks per year as fleet adoptions accelerate nationwide.
Nearly nine years after Elon Musk unveiled the Tesla Semi in November 2017, the company is now opening a dedicated factory just outside of Reno, Nevada, and ramping toward mass production of 50,000 trucks per year.
Volume production began in March 2026 at the new Tesla Semi factory, with the competitive advantage not being the factory itself. Rather, it’s where Tesla built it. By constructing the 1.7 million square foot facility directly adjacent to Gigafactory Nevada in Sparks, Tesla closed the one supply chain loop that had delayed the Semi program for years. The 4680 battery cells that power the Semi are manufactured in the same complex, which significantly streamlines supply logistics. That single decision eliminates the bottleneck that forced Tesla to prioritize battery supply for passenger cars over the Semi throughout 2020, 2021, and 2022, which is precisely why the first deliveries slipped three years past the original target. Every other electric truck manufacturer sources its battery cells from a separate supplier, ships them to a separate factory, and absorbs the cost and delay that comes with that. Tesla built its Semi factory around its battery factory, and that vertical integration is what makes 50,000 trucks per year a realistic number rather than an aspirational one.
At the 2025 Annual Shareholder Meeting, Musk was direct about where things stood, stating “Starting next year, we will manufacture the Tesla Semi. We already have a lot of prototype Semis in operation – PepsiCo and other companies have been using them for some time. But in 2026, we’ll begin volume production at our Northern Nevada factory.” Full ramp to volume output is targeted before June 30, 2026.

The first limited deliveries happened in December 2022 to PepsiCo, which eventually doubled its fleet to 50 trucks out of its California distribution facility. Since then the Semi has been showing up in more corporate fleets. As Teslarati noted in March, a Ralph’s Supermarkets branded Semi was spotted on a Los Angeles highway, confirming Kroger’s partnership with Tesla to deploy up to 500 electric Semis. Walmart, Costco, Sysco, US Foods, DHL, Hight Logistics and WattEV are among the companies actively running or receiving units. DHL logged real-world efficiency of 1.72 kWh per mile under a full 75,000 pound load over 388 miles, matching Tesla’s targets closely.
The 2026 production model arrives with meaningful upgrades over the original, with a 1,000 pound weight reduction, updated aerodynamics, and support for 1.2 MW Megacharger speeds that can restore 60% of range in around 30 minutes during a mandatory driver rest break. Tesla opened its first public Megacharger in Ontario, California in March, positioned near the I-10 and I-15 interchange serving the Ports of Los Angeles and Long Beach. The company plans 37 Megacharger sites by end of 2026 and 66 total across 15 states by early 2027, with construction beginning at the nation’s largest truck stop operator in the first half of this year.

Musk has described the Semi’s economics as a straightforward case. “The Semi is a TCO no-brainer,” he said, noting the total cost of ownership is “much, much cheaper than any other transportation you could have.” At under $300,000, the truck costs roughly double a comparable diesel, but California’s $200,000 per vehicle subsidy has driven over 1,000 state orders alone. As Teslarati has tracked, the prototype fleet accumulated over 13.5 million miles with 95% fleet uptime before production ever scaled. The factory opening now turns that proof of concept into a production program.

Tesla Full Self-Driving gets first-ever European approval
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
Tesla Full Self-Driving (Supervised) got its first-ever European approval, as the Netherlands gave the suite the green light to begin operation.
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
The Dutch vehicle authority RDW granted the type approval after more than 18 months of rigorous testing on both closed tracks and public roads. FSD Supervised complies with UN R-171 standards and benefits from Article 39 exemptions under EU Regulation 2018/858. Importantly, it is not a fully autonomous vehicle.
The RDW stressed that the driver remains fully responsible and must maintain attention at all times. “Safety is paramount for the RDW,” the authority stated. “Proper use of this driver assistance system contributes positively to road safety.” Sensors monitor driver alertness, issuing warnings if eyes leave the road or hands are unavailable to take control immediately.
CEO Elon Musk also commented on the approval in a post on X, saying:
“First (supervised) FSD approval in Europe! Congratulations to the Tesla team and thank you to the regulatory authorities in the Netherlands for all of the hard work required to make this happen.”

Trained on billions of kilometers of real-world driving data, FSD Supervised allows the vehicle to handle residential streets, dense city traffic, and highways under constant supervision. Tesla’s post declared:
“It can drive you almost anywhere under your supervision – from residential roads to city streets & highways. No other vehicle can do this.”
The company added that it is “excited to bring FSD Supervised to more European countries soon.”
This national approval paves the way for broader EU adoption. Other member states can recognize the Dutch certification individually, with a potential bloc-wide rollout via European Commission committee vote anticipated by this Summer. The decision underscores Europe’s stricter safety and documentation requirements compared to U.S. self-certification.
Tesla Europe shares FSD test video weeks ahead of launch target
The Netherlands’ approval represents a pivotal step for Tesla in Europe, where complex regulations and mixed traffic have delayed rollout. Musk added that the RDW was “rigorous” in its assessment of FSD.
By proving the system’s safety in one of the continent’s most bicycle- and tram-heavy nations, Tesla positions itself to transform mobility across the EU—delivering greater convenience while keeping drivers firmly in control.
As the first domino falls, anticipation builds for FSD Supervised to reach additional countries soon.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.
Our @corememory crew went to Nevada to see the line come to life, as it gets ready to pump out thousands of all-electric trucks. We saw the new cab and went on a drive too. Wunderbar! pic.twitter.com/a0S5zVEr87

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.

Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.
