Despite a number of technical hurdles, SpaceX CEO Elon Musk believes that the company’s next-generation Starship spacecraft could eventually be capable of pad aborts in the event of a Super Heavy booster failure before liftoff.

For a vehicle as large and heavy as Starship, this would necessitate a number of compromises, but would undoubtedly serve as a major confidence-booster for prospective passengers in lieu of an established record of reliability. If Starship were capable of pad aborts like the company’s Crew Dragon spacecraft, high-profile and high-value customers like NASA and other space agencies could be far more willing to place astronauts and payloads on what they perceive to be a bizarre but high-performance launch vehicle.

Although SpaceX would almost certainly prefer that Starship and Super Heavy skip the first half of Falcon 9’s life cycle (marked by two catastrophic failures), building a new launch vehicle – particularly one with all new materials, engines, and production processes – is extremely challenging, and failures are to be expected as kinks are worked out.

On the plus side, after several lessons were learned the hard way, SpaceX has demonstrated that it can build an extremely reliable launch vehicle. Since its last catastrophic failure in September 2016, SpaceX has successfully completed 49 launches of Falcon 9 and Falcon Heavy in barely 2.5 years, compared to 29 launches (with 2 failures) from 2010 to 2016. In short, SpaceX has simultaneously proven that it can beat almost any other single provider’s launch cadence and do so with impressive reliability, all while pushing the boundaries of reusable rocketry and constantly upgrading flight hardware.

Destroying customer payloads remains unacceptable, but the ultimate success of SpaceX’s Falcon launch vehicle family – at the cost of two operational failures – is undeniable. With Starship and Super Heavy, SpaceX thankfully has several new advantages, owing to its spectacular success over the last few years. With the fruit of major fundraising in hand, an independent F9/FH launch business humming along, and the freedom to pursue significant R&D projects on its own dime, SpaceX may be able to stomach one or several Starship/Super Heavy failures and do so during internal missions.

By accepting possible (and probable) vehicle failures during development and insulating SpaceX’s external customers from any associated risk, the company should be able to develop Starship and Super Heavy in exactly the ways it wants to.

Hence CEO Elon Musk’s indication that SpaceX “is not planning for pad abort with early Starships”. In short, adding the ability for pad aborts to Starship would/will be a major challenge. Assuming a dry mass of 100 tons (220,000 lb) and a wet mass of 1000-1200 tons (2.2M-2.7M lb), Starship’s six planned Raptor engines – capable of producing up to ~1200 tons of thrust at sea level – could be barely enough to lift a fully-fueled spacecraft. In pad abort scenarios, the rocket booster would be suffering some sort of catastrophic failure, if it wasn’t already mid-explosion. As such, getting far away from said explosion as fast as possible is the name of the game, particularly if the priority is ensuring passenger/astronaut survival.

Starting a high-performance liquid rocket engine fast enough to make an abort possible is also a major challenge, though Musk says that Raptor could be capable of extremely fast start-ups in emergency scenarios. Assuming that Raptor can somehow be ignited from standstill in less than a second (preferably 0.1-0.5s) and would still be able to ignite a second time for a soft landing, SpaceX could technically give Starship the thrust-to-weight ratio needed to quickly escape a Super Heavy failure by reducing the propellant load. With the minimal propellant needed to safely reach a stable low Earth orbit (LEO) during crewed Starship launches, SpaceX would have to lean almost exclusively on rapid orbital refueling, but the combination might be enough to ensure that Starships can abort at almost any point during launch.

It’s extremely unlikely that SpaceX will pursue this capability during the prototype phase, but it may not be out of the question for the first crewed mission(s) of finalized Starships.

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 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.”
