SpaceX set to launch its first previously-flown Block 5 rocket tonight
At the same time as SpaceX is readying its first Falcon 9 Block 5 booster reuse, the company’s second flight-proven Block 5 launch is already fast approaching and could be a strong contender to beat the company’s record of 72 days between launches of the same rocket.
A critical milestone for Falcon 9 Block 5
Formerly known as Telkom 4, SpaceX’s 1:18 AM EDT August 7th launch of the Merah Putih (Red and White in Indonesian) communications satellite will place the 5800 kg (12,800 lb) craft into a high-energy geostationary transfer orbit and will become the second heaviest GTO launch completed by SpaceX while still recovering the Falcon 9 booster. More importantly, however, Telkom 4 will also mark a critical milestone for Falcon 9 as the first reuse of a Block 5 booster.

Designed to be many times more reusable and reliable than the already impressive Falcon 9 Full Thrust iterations preceding it, pathfinder booster B1046 could be capable of flying anywhere from 5, 10, or even 100 launches over the course of its flightworthy lifespan. It very well may require some considerable refinements to approach the true goal of orbital Falcon 9 launches with zero refurbishments between flights. CEO Elon Musk discussed those aspirations just before Block 5’s launch debut on May 11:
“We need to basically take the rocket from its landing pad, rotate it horizontal, stow the legs. Take it to the launch pad, attach an upper stage, attach a fairing with a payload. Then transport it out the launch pad, rotate it vertically, load propellant, and fly. And in principle, that is literally all that’s necessary.” – Elon Musk
This is understandably SpaceX’s goal, and it’s unlikely to happen just a few months after Block 5’s debut. Nevertheless, SpaceX appears to be already pushing the envelope of what they’ve previously accomplished with reusable Falcon 9s.

Breaking records four months after launch debut
While B1046 is tracking towards a booster turnaround of roughly 92 days, compared with the current Block 4 booster record of 72 days, it’s worth noting that more than a majority of that time was likely spent in a state of unique analysis for the inaugural Block 5 rocket, involving extensive disassembly. As stated by Musk, “we need to take [B1046] apart to confirm that it does not need to be taken apart.” He also expected that teardown analysis to be “very rigorous”, indicating that B1046 probably deserves the crown for booster turnaround so long as one only accounts for time spent in transport and undergoing refurbishment.
Still, winning by a technicality is never any fun. On that note, SpaceX appears to be tracking towards a true record-breaking rocket reuse, potentially as few as 40 days between launches. Not one to let its other launch facilities be left out, this record-breaking turnaround attempt will occur on the West Coast with Falcon 9 B1048, the recovery of which has been extensively documented by Teslarati photographer Pauline Acalin over the last two weeks. NASASpaceflight.com confirmed that SpaceX intends to reuse B1048 for this mission for the NET mid-September launch and the record ~50 days between flights could help explain an unusually extensive and lengthy analysis of the rocket after it was lifted off drone ship Just Read The Instructions and placed on its dockside recovery stand.

After 10 days of recovery operations and analysis, B1048 was transported to SpaceX’s Hawthorne factory on August 6th, where it will presumably undergo refurbishment in preparation for its next launch. If B1046 and B1048 are representative samples of SpaceX’s growing rocket fleet, their stunningly quick turnarounds (especially for a largely new rocket that debuted less than 3-4 months prior) are likely a sign of things to come as SpaceX gets a handle on the real-world capabilities of its robust Block 5 upgrade.
It’s entirely possible that every Block 5 reuse to come can and will break the previous launch turnaround record, at least up to the point that SpaceX demonstrates a true 24-hour turnaround sometime next year. Stay tuned…

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:
Robotaxi rides without any safety monitors are now publicly available in Austin.
Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
