SpaceX Falcon 9 nears NASA’s first flight-proven Block 5 launch after static fire delays
After multiple days of delays, many a finger is crossed that SpaceX will be able to perform a critical static fire test of Falcon 9 booster B1056.1 on Friday morning (July 19th).
Falcon 9 B1056 and a fresh upper stage are scheduled to launch Cargo Dragon mission CRS-18 no earlier than 7:35 pm EDT (23:35 UTC), July 21st. As always, SpaceX requires each Falcon 9 rocket to successfully perform a static fire ignition test prior to declaring launch readiness, and B1056 was originally planned to be loaded with propellant and fire its nine Merin 1D engines on Wednesday, July 16th.
After a solid handful of slips, the test has most recently been rescheduled on Friday morning, a delay of 48 hours. SpaceX has demonstrated a three-day turnaround between static fire and launch with Falcon 9 Block 5, but a static fire delay beyond Friday – perhaps even beyond early Friday afternoon – will almost certainly push CRS-18’s launch back a day or two. If not, SpaceX is certainly cutting it close to make the current July 21st date.
In support of Cargo Dragon Commercial Resupply Mission-17 (CRS-17), Falcon 9 B1056 launched for the first time on May 4th, roughly 11 weeks (76 days) ago and 78 days before its planned return to flight. For both SpaceX and NASA, CRS-18 will be a fairly significant launch for a variety of reasons
Falcon2
First and foremost, Falcon 9 B1056 previously supported a NASA Cargo Dragon mission, as described above. Even before the booster successfully landed and returned to port, plans were already in order to essentially keep the booster “in family”, reusing it for NASA launches only. Discussed on Teslarati immediately after the subject was broached during a post-launch press conference, NASA manager Kenny Todd didn’t split hairs.
“Quite frankly, [NASA] had a vested interest in this particular booster. We were gonna require it – the intent is to [reuse B1056 on SpaceX’s upcoming CRS-18 launch] and – potentially – CRS-19.”

Not only will NASA fly Cargo Dragon’s CRS-18 mission on B1056, but the agency is already actively considering reusing the same Falcon 9 booster – assuming a successful launch and landing next week – on CRS-19, SpaceX’s second-to-last Dragon 1 (i.e. Cargo Dragon) launch. If all goes well with CRS-18, CRS-19 could come as early as December 2019, while CRS-20 – likely Dragon 1’s last launch ever – is scheduled no earlier than March 2020 and could certainly make use of B1056.3 if NASA is interested.
Dragon3
Meanwhile, although neither SpaceX or NASA have confirmed it, the Cargo Dragon capsule flight-proven Falcon 9 B1056 will itself be flight-proven – although that’s nothing shocking after a full half-dozen successful launches of reused capsules. What will be exceptional, however, is the likely event that CRS-18 will mark the first time that SpaceX has launched the same Cargo Dragon capsule on its third orbital mission.
Speaking all the way back in summer 2017, now two years distant, SpaceX CEO Elon Musk revealed that Cargo Dragon (Dragon 1) was designed at the outset to be reused three times. Almost exactly 24 months later, SpaceX is likely to prove that that is the case. Based on a list of known Dragon 1 capsules and their serial numbers, SpaceX has already launch and reused all but one of the last seven capsules built and successfully recovered. Capsule 107 (C107) supported CRS-5 in January 2015 and was successfully recovered one month later.
Aside from CRS-7 capsule C109, destroyed in June 2015 during Falcon 9’s first and only in-flight failure, all other capsules (C108-C113) have been successfully launched, recovered, and relaunched. As such, it seems extremely improbable that CRS-5 capsule C107 will be supporting CRS-18. Instead, one of SpaceX’s six twice-flight-proven orbital spacecraft has likely been refurbished for the final time, preparing to become the first orbital-class commercial spacecraft to be reused twice.
Thy Holy Stripe
Finally, it also appears that CRS-18 will mark the debut some sort of on-orbit Falcon upper stage test, hinted at by a grey ring wrapping what looks like just a portion of its fuel (RP-1/kerosene) tank. The objective of this modification is unclear, although chances are good that either NASASpaceflight.com or SpaceX itself will provide at least a bit more information in the coming days.

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.
