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 Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.

Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.
Tesla Optimus Gen 2.5 vs Gen 3 comparison via @WholeMars on X
The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

Tesla Semi lands the biggest electric truck deal in U.S. history
Tesla leads a record 2,500 truck order, but not every truck will be a Semi.
Tesla has landed the largest electric truck order in U.S. history. ZET SCALE, a new alliance of shippers and carriers, named Tesla its primary manufacturer on Tuesday for an initial order of 2,500 electric Class 8 trucks. The deal alone would nearly double the number of electric heavy trucks operating in the country.
According to the press release from Catalyst Mobility, the nonprofit formerly known as CALSTART, Kenworth, RIDE and Volvo were also selected as secondary manufacturers that carriers can pick if their operations call for it. No split between the four brands has been published, so the exact number of Semis in the order is not yet known.

Tesla won the top slot through a competitive request for proposals. The alliance, which Catalyst Mobility runs with the Smart Freight Centre, scored bidders on price, range, charging capability and production capacity. Pooling freight demand from founding shippers, including Microsoft and PepsiCo, let every truck maker bid lower than it would for a single fleet. “The Tesla Semi is designed for lower cost per mile operations than diesel,” said Dan Priestley, director of the Tesla Semi program, as noted in the press release.
The financing is built to pull in carriers who have avoided electric trucks. ZET Financial is issuing the purchase order for all 2,500 units and will place them with fleets through a fair market value lease. The trucks will be deployed over the next few years across 10 freight hubs in Los Angeles, Stockton, Bakersfield, Seattle and Tacoma, Houston, Dallas, San Antonio, Chicago, Atlanta, and the Newark and New York area. ZET SCALE says the first order is only the opening round, with a longer term goal of 10,000 trucks or more.
Even if Tesla ends up with only a majority share, it would still be the biggest Semi deal to date. Einride’s 500 unit order in August was the previous record, and WattEV’s 370 truck order in May was the largest California deal at the time. Einride’s CEO has since said he expects all 500 trucks delivered by the end of 2027.
The announcement lands two days before Tesla formally inaugurates its Semi factory in Nevada on September 24. The 1.7 million square foot plant sits next to Gigafactory Nevada’s 4680 cell lines and is designed for 50,000 trucks a year.
Tesla has expanded Grok from an in-car chatbot into a hands-free work assistant. On September 22, Tesla officially launched Grok Bot capability, confirming that drivers can now manage email, calendars, files, chats, and tasks by voice and then hand more ambitious errands to the AI-fueled productivity cheat code.
Grok itself is built by xAI. The new car features split into two layers: Connectors link Grok to outside accounts. Grok Bot, currently limited to SuperGrok Heavy subscribers, can complete multi-step tasks such as placing a usual coffee order, booking a reservation, or scheduling an appointment. It truly puts the driver in a nearly complete hands-free driving and productivity setting, with ironically the only task truly requiring your hands being to touch the “Start Self-Driving” button.
We were granted access to Grok Bot’s Tesla integration a few weeks back, and we’ve been able to do a handful of things with it. On a handful of occasions, we’ve used it to order food and have it ready for pickup slightly later into the evening; we’ve managed to pick up groceries after a day of errands with Grok Bot, and outside of the car, it’s helped with budgeting and even my fantasy football draft.
We’ve been using @Grok Bot in Tesla for a few weeks after gaining Early Access, which we thank the awesome engineers for

Tesla shows another way to utilize it: in their demo, a driver says “Hey Grok,” asks the assistant to check an inbox, and hears that a message concerns a weekend reservation. Grok then scans the calendar, reports no conflicts, and confirms the Tahoe trip is clear. It can also add check-in details to a road-trip itinerary. The point is not novelty chat. It is keeping eyes on the road, or on Full Self-Driving, while the car handles the paperwork of a trip:

This Grok rollout is not a gadget add-on as much as it is Tesla’s thesis in software form: the car should stop being a machine you operate and start being a room you occupy.
Connectors and Grok Bot treat the cabin as an office that happens to move, and that has truly been Tesla’s intention for years now. The car has slowly become an extension of a home more than a vehicle. Inbox, calendar, groceries, takeout, and reservations become voice work, not dashboard chores that you need to do before you get in your car.
Responsibility shifts from the driver to the stack, and as many Tesla owners rely on FSD for travel, Grok Bot now handles the monotony of dinner reservations or appointments.
