SpaceX sets new Falcon 9 Block 5 reusability milestones for second half of 2019
Speaking at 2019’s Asia-Pacific Satellite (APSAT) Conference, SpaceX Vice President of Commercial Sales Jonathan Hofeller – squeezed into a sea of breaking-news updates – announced that the company plans to launch the same Falcon 9 Block 5 booster for the fifth (or sixth) time by the end of 2019.
Just an add-on at the end of a number of updates focused on SpaceX’s next-generation Starship/Super Heavy rocket, the phrasing reported by SpaceNews.com technically means that there are plans for a Falcon 9 booster to launch for the sixth time in the second half of 2019. The demonstration of such an extreme level of operational reusability barely 18 months after Falcon 9 Block 5’s debut would make it clear that SpaceX’s latest Falcon upgrade has been a resounding success. In line with those positive signs, Hofeller also noted that SpaceX is already starting to transfer the fruits of those labors to its customers by permanently lowering the base price of Falcon 9 launch contracts.
Block 5 off to a spectacular start
First reported on by SpaceNews’ Caleb Henry, one of a few spaceflight journalists able to attend 2019’s Jakarta, Indonesia-based APSAT conference, details about the near-term future of Falcon 9 Block 5 reusability milestones were effectively tacked on at the end of much higher-profile breaking-news tidbits. Although wildly ambitious Starship goals led headlines (stay tuned for Teslarati’s own analysis later this week), the fact remains that ambitious development goals are inherently tenuous and likely to slip, particularly when the subject is large-scale, fully-reusable launch vehicles developed from a nearly blank slate.
What is not up for debate, however, is the fact that SpaceX’s Falcon 9 Block 5 upgrade is already flying routinely and reliably. After a successful debut in May 2018, Block 5 took over all SpaceX launches less than two months later. Since then, a total of 12 freshly-built Block 5 boosters have supported 16 Falcon 9 and 2 Falcon Heavy launches, ten – more than half – of which involved flight-proven boosters. According to official statements made recently by SpaceX executives, Block 5 boosters are expected to support an additional 12-19* launches in the second half of 2019.
*Derived by stacking “2-6 dedicated Starlink launches” and SpaceX’s 2019 target of 18-21 non–Starlink launches
Tied directly to claims that the same Falcon 9 Block 5 booster will launch for the fifth or sixth time by the end of 2019, SpaceX already has three Falcon 9 boosters that have each completed a trio of launches, as well as an additional five with either one or two launches under their belts. Pictured at the top of the article, all three thrice-flown Falcon 9 boosters – B1046, B1048, and B1049 – could arguably be selected to become the next pathfinder as SpaceX prepares to put boosters through their fourth launches and beyond.
Rumored to be assigned to Crew Dragon’s in-flight abort (IFA) test prior to a major capsule anomaly on April 20th, B1046 could be off the manifest if SpaceX is confident that said IFA test can still be performed within the next several months. It’s currently unclear if that is a viable option for SpaceX’s Crew Dragon schedule, likely to remain uncertain until the failure investigation is fully completed and any necessary design/hardware/software fixes have been implemented. B1046 completed its third launch in December 2018 (a full six months ago), followed by B1048 in February 2019 and B1049 in May 2019. Although the “unknown territory” aspect of Block 5 reuse milestones is becoming less noteworthy, SpaceX is still likely to treat B104X’s fourth launch as a pathfinder, requiring extra time to dot I’s and cross T’s. With B1046 and B1048 potentially ready to go, that milestone could come any time now.
SpaceX customers already reaping financial benefits
Meanwhile, although certain heads-in-sand competitors continue to act and claim otherwise, SpaceX has reportedly normalized earlier prices for customers flying on flight-proven milestone missions. Speaking at APSAT, SpaceX’s Jonathan Hofeller indicated that that pricing is now the company’s “normal pricing”, pushing Falcon 9’s base price as low as ~$50M according to comments CEO Elon Musk made about a year ago. Two years prior to those comments and about six months prior to SpaceX’s first-ever booster reuse, COO and President Gwynne Shotwell reported that the company was offering discounts of ~10% for customers willing to contract launches on flight-proven Falcon 9 boosters.
In other words, SpaceX has cut Falcon 9’s base launch costs by anywhere from 10-20% over the last three years, a period in which the Falcon 9 V1.2 Full Thrust rocket’s capabilities were also dramatically upgraded from Block 1 (debut: December 2015) through Block 5 (debut: May 2018). Speaking during a press conference focused on Falcon 9 Block 5’s launch debut, CEO Elon Musk estimated that SpaceX has spent more than $1 billion to develop Falcon 9 reusability, while he previously estimated Falcon Heavy’s development costs to be well north of ~$500M. Musk and other execs have previously confirmed that SpaceX means to recoup some or all of that investment, indicating that the current margins of Falcon 9 launch contracts must be extremely favorable.
SpaceX has a healthy commercial manifest and will need to support dozens to hundreds of its own dedicated Starlink launches in order to orbit an operational and profitable constellation.

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.

— Elon Musk (@elonmusk) March 11, 2026
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.

Tesla adds awesome new driving feature to Model Y
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla writes in the release notes for the feature:
“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

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.
