SpaceX sends reused Falcon 9 booster west for first California Starlink launches
SpaceX has shipped the first of one or two flight-proven Falcon 9 boosters from Florida to California in the latest sign that the company is preparing to begin dedicated polar Starlink launches in the near future.
On May 27th, a Reddit post revealed a Falcon 9 booster arriving at Vandenberg Air/Space Force Base (VAFB), the home of SpaceX’s West Coast SLC-4E launch pad. Only truly useful for polar or high-inclination launches with satellites that need to orbit the Earth’s poles instead of the equator, SpaceX has only used SLC-4E twice in the last two years – once in June 2019 and most recently in November 2020.
Now, amidst a major hiring spree and rare new activity at a nearby Los Angeles port, SpaceX is clearly gearing up to return its SLC-4E launch pad to active duty.
B1049 began its career in Florida (Telstar 18V), moved to Vandenberg for its second flight (Iridium-8), went back to Florida for seven Starlink missions, and is once again returning to the best coast.— Michael Baylor (@nextspaceflight) May 27, 2021
Both recent West Coast Falcon 9 missions hosted booster landings at LZ-4, a landing zone situated a little over 1000 feet (300m) away from the launch pad. That freed up SpaceX to ship former West Coast drone ship Just Read The Instructions (JRT) across the Panama Canal in August 2019, where it ultimately joined the company’s Florida rocket recovery fleet in early 2020 to support a major launch cadence ramp.
As a partial result, SpaceX was able launch Falcon 9 26 times in 2020, beating the previous record – 21 flights – by almost a quarter. In 2021, SpaceX is well on its way to smashing that annual launch record again and has completed 16 orbital launches with seven full months left in the year. That cadence is pushing SpaceX’s launch pads, recovery ships, and booster fleet to their limits. Due to the voracious demands of SpaceX’s almost weekly launch cadence, the company would only be shipping a workhorse booster to Vandenberg if there was a pressing need for it.
Said to be Falcon 9 B1049 by Next Spaceflight and NASASpaceflight reporter Michael Baylor, the booster that arrived at Vandenberg Air Force Base on Thursday has flown nine times – two of which it completed in February and May 2021. B1049 hasn’t been the most rapidly reusable of the fleet and is the oldest Falcon booster still operational after debuting in September 2018. However, SpaceX’s SLC-4E is relatively old itself and recruiting documents distributed as recently as 2021 indicated that the company’s West Coast resurgence was targeting a maximum cadence of one launch per month.
Virtually all of those missions will carry the company’s own Starlink satellites. On Wednesday, May 26th, SpaceX completed its 28th operational East Coast Starlink launch, effectively completing the first ‘tranche’ of the constellation once the satellites already in space reach their operational orbits. In April, SpaceX COO and President Gwynne Shotwell stated that polar Starlink launches would begin not long after that 28-launch milestones.
The day before B1049 arrived, SpaceX filed the first regulatory documents for at least six Vandenberg Starlink launches between July 2021 and January 2022 – one mission per month. It’s hard to say when the first launch will come. With B1049 now on site, FCC permits in work, and a new berth lease active in Port of Long Beach, the only real piece of the equation missing is a drone ship to support polar Starlink launches. According to said FCC documents, SpaceX will continue to push Falcon 9 to its limits on the West Coast, recovering boosters 640 km (~400 mi) downrange after polar Starlink launches.
SpaceX’s two operational drone ships – OCISLY and JRTI – currently have their hands full on the East Coast. Transporting either to California will take several weeks, limiting SpaceX’s East Coast launch cadence during that period. SpaceX and its contractors are currently hard at work completing a third drone ship – A Shortfall of Gravitas (ASOG), but past experience suggests that the vessel is at least a few months away from completion.
Once a drone ship has arrived at SpaceX’s new West Coast docks, though, the company will have almost everything it needs to kick off polar Starlink launches.
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.
Tesla shows rapid teardown of Model S and X lines, paving the way for Optimus at Fremont
Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.

Tesla reveals 2026 Summer Update with crazy fixes to Nav and more
Tesla (NASDAQ: TSLA) will report its earnings for the second quarter of 2026 this evening after market close, and investors and analysts are waiting anxiously to see what the company will report for the second three-month span of the year.
Analysts have already put out their expectations from a financial standpoint for the company’s second quarter, but what’s unknown is what Tesla plans to discuss during the call.
Financial Expectations
Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.53, while revenues are expected to come in around $26.4 billion.
This would compare to an EPS of $0.39 and $22.19 billion compared to Tesla’s Q2 2025. Last quarter, EPS came in at $0.41 on $22.387 billion of revenue. Additionally in Q1, Tesla beat analyst expectations, but shares dropped over 3 percent the following trading day.
What We Expect
In terms of discussions, Tesla earnings are pretty sporadic and depend on a handful of things, including current events, investor questions, and more.
Tesla uses a platform called Say to field questions from investors and analysts. These questions are what will be used during the call. Here are the top 5 from the Retail side and top 3 from the Institutional side:
Retail:
“Tesla has missed short-term guidance on robotaxi 3 earnings reports in a row, from 50% coverage of USA by end of 2025 to most recently 7 new cities in 1H26. What is keeping Tesla back from accomplishing these short term goals that they’ve set for themselves?”
“What are the main constraints to expanding robotaxi operations faster, and how do you see that lining up with Cybercab production?”
“What’s the current status of Optimus Gen 3 production ramp, initial deployment in factories, and external sales timeline/volume for 2027? What tasks can we expect the Optimus to perform by end of 2027?”
“To reward long-term Tesla retail shareholders for their loyalty, can you commit to achieving at least half of the goals outlined in your 2025 compensation plan before considering any offers to acquire or merge Tesla?”
“Why has growth of robotaxi vehicles stalled? When will we see cybercab start customer rides?”
Institutional
“Previously, you’ve said Tesla would lead the R&D while SpaceX would lead production for Terafab. Can you provide an update on how that division of responsibilities is evolving, and any additional clarity on the expected capital contributions from Tesla and SpaceX?”
“For autonomous driving, Tesla’s fleet created a huge data advantage by collecting billions of real-world miles. That advantage doesn’t yet exist for Optimus. How should we think about data availability and its impact on Optimus development?”
“Why is it necessary to limit robotaxi operations within specific zones within cities to start? Will every city have to be rolled out this way?”
Tesla will report earnings for Q2 this evening with the Shareholder Deck at 4 p.m. ET, with the call starting around 5:30 p.m. ET.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
