SpaceX’s Elon Musk talks Starship heatshield, rocket landings on Joe Rogan podcast

Published

on

In a multi-hour February 2021 interview with Elon Musk himself, Joe Rogan inexplicably told the famous engineer and CEO that he had never seen a SpaceX rocket landing.

Of course, the 200+ minute conversation did produce a few minor tidbits of interesting information about SpaceX (and much more about Tesla projects), but Rogan’s statement that he’d never seen a SpaceX rocket landing before stole the limelight by a long shot.

SpaceX landed its first Falcon 9 booster – to an extraordinary amount of fanfare – in December 2015. In the five years since that breakthrough, SpaceX has successfully landed Falcon boosters 73 more times. A full 26 of those landings occurred in just the last 12 months. Falcon Heavy – responsible for spectacular, crowd-favorite performances – completed three dual-booster landings and one triple-booster landing between February 2018 and June 2019.

It’s not unimaginable that almost every single human on Earth with some level of access to the internet or social media is at least vaguely aware of or has watched videos of SpaceX landing rockets. To be clear, it is an unequivocal fact – including past comments on landings from Rogan himself – that Rogan has watched SpaceX land Falcon boosters at least once, if not several times. The only real takeaway, fellow readers, is that heavy, long-term drug use is inadvisable.

Cringeworthy moments aside, the interview did produce a select few minor details that weren’t explicitly known before. Most notably, Musk briefly discussed the challenge of developing a heat shield capable of safely returning orbital Starships back to Earth and revealed the main issue that SpaceX is currently working on.

Over the last six or so months, SpaceX has been gradually expanding small installations of heat shield tiles on Starship prototypes, ranging from vehicles that never left the ground to high-altitude Starships SN8 and SN9. Those tile installations have grown from a handful (4-8 on Starhopper in 2019) to literal hundreds on the most recent Starship completed by SpaceX.

During earlier ground testing and more recent hop tests with Starships SN5 and SN6, some of those ceramic composite tiles actually fell off or shattered, perhaps due to vibrations from Raptor engines or mechanical stress caused by Starship shrinking and contracting from thermal expansion. According to Musk, what SpaceX is trying to determine with those coupon-style tests is how to install a heat shield with tiles that are neither too close together or too far apart.

According to Musk, ceramic heat shield tiles placed too close together will ultimately shatter, break, or fall off when subjected to the stresses of Starship operations. Those stresses include the violent vibrations created by rocket propulsion supersonic to hypersonic travel, as well as airframe expansion and contraction that occurs when Starship’s steel hull is cyclically heated and cooled by Raptor burns and cryogenic propellant. In other words, assuming fragile, ceramic tiles are a necessity, they need to be placed far enough apart to avoid all of those possible pitfalls.

On the opposite hand, though, the entire point of Starship’s heat shield is to insulate it from extreme thermal stress during atmospheric reentry. If individual tiles are situated too far apart, superheated gas (plasma) produced during reentry will find its way between those tiles, heating up the structure they’re meant to keep cool. In the case of Starship, its steel hull is more than twice as resilient to reentry heating than comparable vehicles (like the Space Shuttle) with common aluminum frames, but a few millimeters of steel is still not enough to prevent weakening, damage, or outright burn-through in the face of orbital reentry.

In essence, SpaceX has to “get the gaps just right” – not too far apart to protect the airframe from plasma intrusion but not so close together that tiles impact or damage their neighbors as Starship cools and warms.

Tesla announces crazy new Full Self-Driving milestone

The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.

Tesla has announced a crazy new Full Self-Driving milestone, as it has officially confirmed drivers have surpassed over 8 billion miles traveled using the Full Self-Driving (Supervised) suite for semi-autonomous travel.

The FSD (Supervised) suite is one of the most robust on the market, and is among the safest from a data perspective available to the public.

On Wednesday, Tesla confirmed in a post on X that it has officially surpassed the 8 billion-mile mark, just a few months after reaching 7 billion cumulative miles, which was announced on December 27, 2025.

The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.

The milestone itself is significant, especially considering Tesla has continued to gain valuable data from every mile traveled. However, the pace at which it is gathering these miles is getting faster.

Secondly, in January, Musk said the company would need “roughly 10 billion miles of training data” to achieve safe and unsupervised self-driving. “Reality has a super long tail of complexity,” Musk said.

Training data primarily means the fleet’s accumulated real-world miles that Tesla uses to train and improve its end-to-end AI models. This data captures the “long tail” — extremely rare, complex, or unpredictable situations that simulations alone cannot fully replicate at scale.

This is not the same as the total miles driven on Full Self-Driving, which is the 8 billion miles milestone that is being celebrated here.

The FSD-supervised miles contribute heavily to the training data, but the 10 billion figure is an estimate of the cumulative real-world exposure needed overall to push the system to human-level reliability.

Tesla Cybercab production begins: The end of car ownership as we know it?

While this could unlock unprecedented mobility abundance — cheaper rides, reduced congestion, freed-up urban space, and massive environmental gains — it risks massive job displacement in ride-hailing, taxi services, and related sectors, forcing society to confront whether the benefits of AI-driven autonomy will outweigh the human costs.

The first Tesla Cybercab rolled off of production lines at Gigafactory Texas yesterday, and it is more than just a simple manufacturing milestone for the company — it’s the opening salvo in a profound economic transformation.

Priced at under $30,000 with volume production slated for April, the steering-wheel-free, pedal-less Robotaxi-geared vehicle promises to make personal car ownership optional for many, slashing transportation costs to as little as $0.20 per mile through shared fleets and high utilization.

While this could unlock unprecedented mobility abundance — cheaper rides, reduced congestion, freed-up urban space, and massive environmental gains — it risks massive job displacement in ride-hailing, taxi services, and related sectors, forcing society to confront whether the benefits of AI-driven autonomy will outweigh the human costs.

Let’s examine the positives and negatives of what the Cybercab could mean for passenger transportation and vehicle ownership as we know it.

The Promise – A Radical Shift in Transportation Economics

Tesla has geared every portion of the Cybercab to be cheaper and more efficient. Even its design — a compact, two-seater, optimized for fleets and ride-sharing, the development of inductive charging, around 300 miles of range on a small battery, half the parts of the Model 3, and revolutionary “unboxed” manufacturing — is all geared toward rapid production.

Operating at a fraction of what today’s rideshare prices are, the Cybercab enables on-demand autonomy for a variety of people in a variety of situations.

It could also be the way people escape expensive and risky car ownership. Buying a vehicle requires expensive monthly commitments, including insurance and a payment if financed. It also immediately depreciates.

However, Cybercab could unlock potential profitability for owning a car by adding it to the Robotaxi network, enabling passive income. Cities could have parking lots repurposed into parks or housing, and emissions would drop as shared electric vehicles would outnumber gas cars (in time).

The first step of Tesla’s massive production efforts for the Cybercab could lead to millions of units annually, turning transportation into a utility like electricity — always available, cheap, and safe.

The Dark Side – Job Losses and Industry Upheaval

With Robotaxi and Cybercab, they present the same negatives as broadening AI — there’s a direct threat to the economy.

Uber, Lyft, and traditional taxis will rely on human drivers. Robotaxi will eliminate that labor cost, potentially displacing millions of jobs globally. In the U.S. alone, ride-hailing accounts for billions of miles of travel each year.

There are also potential ripple effects, as suppliers, mechanics, insurance adjusters, and even public transit could see reduced demand as shared autonomy grows. Past automation waves show job creation lags behind destruction, especially for lower-skilled workers.

Gig workers, like those who are seeking flexible income, face the brunt of this. Displaced drivers may struggle to retrain amid broader AI job shifts, as 2025 estimates bring between 50,000 and 300,000 layoffs tied to artificial intelligence.

It could also bring major changes to the overall competitive landscape. While Waymo and Uber have partnered, Tesla’s scale and lower costs could trigger a price war, squeezing incumbents and accelerating consolidation.

Balancing Act – Who Wins and Who Loses

There are two sides to this story, as there are with every other one.

The winners are consumers, Tesla investors, cities, and the environment. Consumers will see lower costs and safer mobility, while potentially alleviating themselves of awkward small talk in ride-sharing applications, a bigger complaint than one might think.

Elon Musk confirms Tesla Cybercab pricing and consumer release date

Tesla investors will be obvious winners, as the launch of self-driving rideshare programs on the company’s behalf will likely swell the company’s valuation and increase its share price.

Cities will have less traffic and parking needs, giving more room for housing or retail needs. Meanwhile, the environment will benefit from fewer tailpipes and more efficient fleets.

A Call for Thoughtful Transition

The Cybercab’s production debut forces us to weigh innovation against equity.

If Tesla delivers on its timeline and autonomy proves reliable, it could herald an era of abundant, affordable mobility that redefines urban life. But without proactive policies — retraining, safety nets, phased deployment — this revolution risks widening inequality and leaving millions behind.

The real question isn’t whether the Cybercab will disrupt — it’s already starting — it’s whether society is prepared for the economic earthquake it unleashes.
