SpaceX’s first West Coast rocket launch in almost a year and a half is back on track after an October 2nd Falcon 9 launch abort triggered several different delays.

Deemed Sentinel-6A Michael Freilich after the late US oceanographer and former NASA Earth Sciences director, Falcon 9 will launch the ~1500 kg (~3300 lb) spacecraft into low Earth orbit, where it will nominally spend a decade or more precisely measuring the height of the ocean surface to track sea level rise, ocean currents, heat distribution, and more.

Minutes after launch, new Falcon 9 booster B1063 will also attempt to land back at Landing Zone 4 (LZ-4), situated barely a thousand feet away from the launch pad. Sentinel-6A will be SpaceX’s first launch from the West Coast since it orbited Canada’s Radarsat Constellation Mission (RCM) satellite trio in June 2019, as well as SpaceX’s third LZ-4 booster recovery ever.

On October 28th, NASA convened a press conference call to provide an update on an investigation SpaceX and the space agency were conducting into October 2nd’s Falcon 9 launch abort. By then, the company had concluded that the abort had been caused by a slip in quality assurance that allowed improperly cleaned vendor parts to slip through the cracks.

“According to SpaceX vice president of build and flight reliability Hans Koenigsmann, in the course of the rapid and complex mechanical and electrical ballet preceding Falcon 9 first stage ignition, the rocket’s autonomous flight computer observed that two of the GPS III SV04 booster’s nine Merlin 1D engines appeared to be running ahead of schedule, so to speak. The computer immediately halted the ignition process to avoid what could have otherwise been a “hard” (i.e. stressful or damaging) start. SpaceX quickly began inspecting the rocket within 24 hours but was unable to detect anything physically or electrically wrong with Falcon 9’s Merlin 1D engines and engine section.

Out of an abundance of caution, SpaceX removed both misbehaving engines and shipped them to its McGregor, Texas development and test facilities where – somewhat miraculously – the same premature startup behavior was replicated on the test stand. After a great deal of increasingly granular inspections, SpaceX finally narrowed the likely cause down to a tiny plumbing line feeding one of the engine’s gas generator relief valves. In a seemingly random subset of relatively new Merlin 1D engines, SpaceX eventually discovered that a supplier-provided relief valve line was sometimes clogged by a protective lacquer Koenigsmann likened to “red nail polish.

When SpaceX uncovered the possible cause and cleaned out the blocked plumbing, each previously affected Merlin 1D engine performed perfectly, all but directly confirming both the cause and the cure for Falcon 9’s October 2nd abort.”

As part of the investigation, SpaceX traced similar bad behavior back to engines on more than just the Falcon 9 booster (B1062) involved in the GPS III SV04 launch abort, ultimately impacting both Falcon 9 booster B1061 – assigned to launch four NASA astronauts to the ISS – and B1063 – assigned to launch Sentinel-6A.

Per Kathy Lueders, NASA’s Associate Administrator of the Human Exploration and Operations Mission Directorate (HEOMD), SpaceX has ultimately decided to replace two of the Sentinel-6A booster’s nine Merlin 1D engines out of an abundance of caution. Formerly scheduled to launch no earlier than (NET) November 10th, the new Falcon 9 rocket is now tracking towards its first Sentinel-6A launch attempt on Saturday, November 21st.

BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor

Published

on

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:

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 Earnings Call: Top 5 questions investors are asking

Published

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:

SpaceX IPO is coming, CEO Elon Musk confirms

  1. You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
    1. 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.
  2. When is FSD going to be 100% unsupervised?
    1. 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.
  3. 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?
    1. 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.
  4. 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?
    1. Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
  5. 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.
    1. 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 shares incredible detail about Tesla Cybercab efficiency

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.

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.”
