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.

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

Tesla Supercharger Diner officially opens: menu, prices, features, and more

Tesla has officially opened its Supercharger Diner in Los Angeles to the public for the first time. It is an 80-Supercharger lot with two movie screens and a full-service 24/7 diner that serves a wide variety of locally sourced food for patrons while they charge or even just stop by.

It is not exclusive to Tesla owners, as anyone can stop by to experience the Diner and movie theater. It officially opened to the public at 4:20 p.m. local time.

In 2018, CEO Elon Musk said he was hoping to build a full-scale 50s era diner that served as a drive-in movie theater. Seven years later, it has officially come to life, and in typical Tesla fashion, it opened at a very appropriate time of day. We heard of people waiting as many as 13 hours for the site to open.

Elon Musk’s Neuralink posts massive update with new milestone

This is the first time Neuralink has successfully implanted two patients in a single day.

Elon Musk’s Neuralink has posted a massive update with a new milestone that puts the company’s progress into perspective. Over the past few years, we have seen tremendous strides in Neuralink’s capabilities.

Now, the company has completed a new first, bringing more hope to the future of this revolutionary technology.

Neuralink’s third brain chip patient shares first video edited with BCI

Neuralink revealed in an update on Monday morning that it has officially completed two implants in a single day, with Patients 8 and 9 both receiving devices over the past weekend.

“Both participants are recovering well and in great spirits,” the company said in the short update. It did not disclose which day the surgeries were completed, but it did state explicitly that they both occurred on the same day:

Musk said that Neuralink’s capabilities could do “life-changing good for ultimately millions, maybe billions, of people.” Right now, it is being used to help combat life-altering diseases, such as ALS, also known as Lou Gehrig’s Disease, as well as cervical spinal cord injuries.

Eventually, Neuralink could resolve things like anxiety, depression, and blindness, among many other ailments.

Its Link device also received FDA recognition for speech restoration earlier this year, marking a significant bit of progress in the program as it explores ways to cure ailments of various natures.

Elon Musk gives key update on plans for Tesla Diner outside of LA

More Tesla Supercharger Diners are on the way, Elon Musk says, as long as the initial one is successful.

Elon Musk has given a key update on its plans for the Tesla Supercharger Diner, as the first location in Los Angeles is set to open today, July 21.

The idea for the Supercharger Diner, which resembles a 50s-style eatery with elements of futuristic technology, is seven years in the making. Many wondered whether Tesla would expand its idea for a Supercharger restaurant outside of LA, and now we have an answer directly from Musk.

Elon Musk confirms awesome new features at Tesla Diner Supercharger

The Tesla CEO said that the company will establish these types of experiences “in major cities around the world, as well as at Supercharger sites on long distance routes.”

The Supercharger Diner has plenty of ways to draw in customers, and although the food and merchandise sold at the location will not be a major contributor to Tesla’s balance sheet, where investors want to see it, it could pay off in other ways.

The Diner is not exclusive to Tesla owners, so those who drive gas cars can still stop in for a burger, fries, and a shake while roaming around Los Angeles. The features of the Diner, however, do require a Tesla vehicle.

In-car ordering and movie screens syncing to the center touchscreen are two things that Tesla owners will enjoy that other drivers will not. These might be trivial, but the experience on its own could be a way that some consider buying a Tesla.

It might sound crazy that a singular diner experience would flip someone to buy a car, but it’s not the most outlandish thing we’ve ever come across.

The question is where Tesla will plan to build these Supercharger Diners. Musk has already indicated that Starbase, Texas, will be one location, which fits with one of his other companies, SpaceX.

Austin could be an ideal location, but New York, Miami, Washington D.C., Boston, and plenty of other popular metro areas within the U.S. could see their own diners in the coming years.
