SpaceX, Firefly Aerospace targeting three rocket launches in two days
Update: As is a common occurrence in spaceflight, two of the three planned missions have been delayed or scrubbed. Firefly’s second Alpha launch has slipped to no earlier than (NET) September 12th after an aborted attempt on the 11th, and SpaceX’s Starlink 4-34 mission was pushed from September 11th to September 13th.
SpaceX and Firefly Aerospace are on track to attempt three orbital launches this weekend as the former continues to relentlessly assemble a constellation of Starlink internet satellites and the latter works to secure its first success.
On the heels of 40 successful Falcon 9 launches this year, SpaceX is a few days away from two more Starlink missions that will likely leave the company with more than 3000 working satellites in orbit.
Founded in 2017, 15 years after SpaceX, Firefly Aerospace is almost entirely focused on one near-term goal: the first successful launch of its Alpha rocket.
Firefly’s Alpha rocket lifted off for the first time on September 2nd, 2021. Just moments after launch, a faulty cable caused one of the Alpha first stage’s four Reaver engines to shut down, immediately dooming the attempt. The rocket inexplicably persevered, though, and managed more than two minutes of powered flight before it lost control, became a range safety risk, and was terminated.
More than a year later, Firefly believes it has solved the problems that doomed Alpha Flight 1 and is on the cusp of the rocket’s second launch attempt, which has been scheduled no earlier than (NET) 3pm PST (22:00 UTC) on Sunday, September 11th.
Recently, the second fully stacked Alpha rocket completed a wet dress rehearsal and static fire while installed on Firefly’s Vandenberg Space Force Base (VSFB) SLC-2W pad, confirming its readiness for flight. Measuring 1.8 meters (6 ft) wide and 29.5 meters (~95 ft) tall, Alpha is about half the width and height of SpaceX’s Falcon 9 workhorse, and Firefly estimates that the expendable rocket will be able to launch up to 1.17 tons (~2560 lb) to Low Earth Orbit (LEO).
That’s several times more performance per launch than competitors like Rocket Lab, Astra Space, and Virgin Orbit, but 14 times less than a partially reusable Falcon 9. At $15 million apiece, however, the rocket’s list price will be 4.5 times less than Falcon 9’s, which could be enough to create a niche for customers that want to spend a bit more to send smaller satellites exactly where they want instead of getting dropped off in the general vicinity as a rideshare payload.
Demonstrating an impressive level of transparency, Firefly will offer a public livestream of Alpha’s second flight in full awareness that it could ultimately broadcast a launch failure for the second time in a row. There are very few instances in the history of spaceflight where a new group’s new rocket successfully reached orbit on its first launch, so it’s a credit to the startup to acknowledge the reality that launch failures are a common extension of the development process, rather than something to hide from the public.
SpaceX knows that reality well. Falcon 1, its first rocket, was about half the size of Firefly’s Alpha and suffered three launch failures in two and half years before finally succeeding on its fourth attempt. More than a magnitude larger, Falcon 9 likely benefitted from SpaceX’s Falcon 1 experience and had a much smoother start to life, though it did eventually experience its own share of failures years after its 2010 debut.
12 years later, Falcon 9 is one of the most successful launch vehicles of all time, and has simultaneously pioneered the commercially viable reuse of orbital-class rockets. Currently on a historic pace of one launch every ~6.2 days in 2022, Falcon 9 recently completed its 146th successful launch in a row and 173rd successful launch overall.
Hopefully continuing those trends, Next Spaceflight reports that Falcon 9 is scheduled to launch two more batches of Starlink satellites at 9:10 pm EDT on Saturday, September 10th, and 10:53 pm EDT on Sunday, September 11th. In addition to several dozen Starlink satellites, the first mission – Starlink 4-2 – is expected to carry a relatively large 1.5-ton (~3300 lb) satellite prototype for space-to-phone communications startup AST SpaceMobile. The second mission, known as Starlink 4-34, should be a dedicated launch of another 53 or 54 Starlink satellites.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
