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 dominates JD Power EV Satisfaction ranking, grabbing top two spots

The Model 3 was the highest ranking EV considered, with a score of 804, followed by the Model Y at 797, the BMW i4 at 795, and the BMW iX at 794.

Tesla dominated JD Power’s EV Owner Satisfaction ranking for 2026, grabbing the top two spots in the survey with the Model 3 and Model Y.

The two Tesla models grabbed the first and second spots, respectively, with scores of 804 and 797 out of 1,000 possible points.

Brent Gruber, Executive Director of JD Power’s EV practice, said:

“EV market share has declined sharply following the discontinuation of the federal tax credit program in September 2025, but that dip belies steadily growing customer satisfaction among owners of new EVs. Improvements in battery technology, charging infrastructure, and overall vehicle performance have driven customer satisfaction to its highest level ever. What’s more, the vast majority of current EV owners say they will consider purchasing another EV for their next vehicle, regardless of whether they benefited from the now-expired federal tax credit.”

JD Power’s study showed three key findings: Public charging satisfaction was higher than ever, premium BEVs saw more pronounced quality improvements, and BEVs held their satisfaction ratings compared to plug-in hybrid electric vehicles (PHEVs).

Tesla Grabs Top 2 Spots

Despite what some publications might try to make you believe, Tesla is still the cream of the crop when it comes to EV ownership, and real-world owners surveyed by JD Power will prove that to you.

The Model 3 was the highest ranking EV considered, with a score of 804, followed by the Model Y at 797, the BMW i4 at 795, and the BMW iX at 794. The segment average for “Premium Battery Electric Vehicles” was 786. The Cadillac OPTIQ (762), Rivian R1S (758), Lucid Air (740), Rivian R1T (739), and Audi Q6 e-Tron (690) all finished below that threshold.

Meanwhile, a separate category for “Mass Market Battery Electric Vehicles” had the Ford Mustang Mach-E as the EV with the highest rating at 760. The segment average for this class was 727.

Tesla Supercharging Improves Public Charging Satisfaction

JD Power said the availability of public charging is “by far the most improved index factor,” and that the consistent growth of publicly available charging has helped push many consumer sentiments in a positive direction.

Most of this is due to the Tesla Supercharger Network and its expansion. However, Tesla owners are also becoming more satisfied with the infrastructure after expanding access to other EV brands, the study said.

Musk company boycott proposal at City Council meeting gets weird and ironic

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal to ban Musk-operated companies. It got weird and ironic.

A city council meeting in California that proposed banning the entry of new contracts with companies controlled by Elon Musk got weird and ironic on Tuesday night after councilmembers were forced to admit some of the entities would benefit the community.

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal called “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies.”

The proposal claimed that Musk ” has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”

We reported on it on Tuesday before the meeting:

California city weighs banning Elon Musk companies like Tesla and SpaceX

However, the meeting is now published online, and it truly got strange.

While it was supported by various members of the community, you could truly tell who was completely misinformed about the influence of Musk’s companies, their current status from an economic and competitive standpoint, and how much some of Musk’s companies’ projects benefit the community.

City Council Member Admits Starlink is Helpful

One City Council member was forced to admit that Starlink, the satellite internet project established by Musk’s SpaceX, was beneficial to the community because the emergency response system utilized it for EMS, Fire, and Police communications in the event of a power outage.

After public comments were heard, councilmembers amended some of the language in the proposal to not include Starlink because of its benefits to public safety.

One community member even said, “There should be exceptions to the rule.”

Community Members Report Out of Touch Mainstream Media Narratives

Many community members very obviously read big bold headlines about how horribly Tesla is performing in terms of electric vehicles. Many pointed to “labor intimidation” tactics being used at the company’s Fremont Factory, racial discrimination lawsuits, and Musk’s political involvement as clear-cut reasons why Davis should not consider his companies for future contracts.

However, it was interesting to hear some of them speak, very obviously out of touch with reality.

Musk has encouraged unions to propose organizing at the Fremont Factory, stating that many employees would not be on board because they are already treated very well. In 2022, he invited Union leaders to come to Fremont “at their convenience.”

The UAW never took the opportunity.

Some have argued that Tesla prevented pro-union clothing at Fremont, which it did for safety reasons. An appeals court sided with Tesla, stating that the company had a right to enforce work uniforms to ensure employee safety.

Another community member said that Tesla was losing market share in the U.S. due to growing competition from legacy automakers.

“Plus, these existing auto companies have learned a lot from what Tesla has done,” she said. Interestingly, Ford, General Motors, and Stellantis have all pulled back from their EV ambitions significantly. All three took billions in financial hits.

One Resident Crosses a Line

One resident’s time at the podium included this:

He was admonished by City Council member Bapu Vaitla, who said his actions were offensive. The two sparred verbally for a few seconds before their argument ended.

City Council Vote Result

Ultimately, the City of Davis chose to pass the motion, but they also amended it to exclude Starlink because of its emergency system benefits.

Saudi artificial intelligence firm HUMAIN has confirmed a $3 billion Series E investment in xAI just weeks before the startup’s merger with SpaceX.

The transaction converts HUMAIN’s xAI stake into SpaceX shares, positioning the Saudi-backed firm as a significant minority shareholder in the newly combined entity.

The investment gives HUMAIN exposure to what has been described as one of the largest technology mergers on record, combining xAI’s artificial intelligence capabilities with SpaceX’s scale, infrastructure, and engineering base, as noted in a press release.

“This investment reflects HUMAIN’s conviction in transformational AI and our ability to deploy meaningful capital behind exceptional opportunities where long-term vision, technical excellence, and execution converge, xAI’s trajectory, further strengthened by its acquisition by SpaceX, one of the largest technology mergers on record, represents the kind of high-impact platform we seek to support with significant capital” HUMAIN CEO Tareq Amin stated.

The investment also positions HUMAIN for potential long-term equity upside should SpaceX proceed with a public offering.

The investment expands on an existing partnership announced in November 2025 at the U.S.-Saudi Investment Forum. Under that agreement, HUMAIN and xAI committed to jointly develop more than 500 megawatts of next-generation AI data center and compute infrastructure in Saudi Arabia.

The collaboration also includes deployment of xAI’s Grok models within the kingdom, aligning with Saudi Arabia’s broader strategy to build domestic AI capacity and attract global technology players.

HUMAIN, backed by the Public Investment Fund, is positioning itself as a full-stack AI player spanning advanced data centers, cloud infrastructure, AI models, and applied solutions. The Series E investment deepens its role from development partner to major shareholder in the Musk-led AI and space platform.
