SpaceX has silently published the first known detailed render of its new stainless steel Starship’s design on the cover of Popular Mechanic’s April 2019 issue, showing the next-generation orbital spacecraft reentering Earth’s atmosphere in a blaze of glowing metal and plasma.

Despite the fact that the render seems to only be available in print and then only through one particular news outlet, Teslarati has acquired a partial-resolution copy of the image to share the latest official glimpse of SpaceX’s Starship with those who lack the means, access, or interest to purchase a magazine. Matters of accessibility aside, SpaceX’s updated render offers a spectacular view of Starship’s exotic metallic heat shield in action, superheating the atmosphere around it to form a veil of plasma around the spacecraft’s hull. According to CEO Elon Musk, the hottest parts of Starship’s skin will be reinforced with hexagonal tiles of steel and transpiration cooling, a largely unproven technology that SpaceX is already in the process of testing.

Aside from one additional view – again only distributed to Popular Mechanic – showing a far wider angle of a SpaceX Starship entering the Martian atmosphere and video shown by CEO Elon Musk to students in Flint, MI a few days ago, this appears to be the first official render of an unequivocally metallic Starship. Aside from its shiny steel exterior, this latest render also offers an exceptionally-illustrated artist’s interpretation of what a Starship with metallic thermal protection might look like during reentry, appearing to take into account a number of things that set such a system apart from traditional heat shielding.

Aside from NASA’s Space Shuttle, which used fragile tiles of insulating material in its reusable heat shield, no other spacecraft have been flown with a primary heat shields that experiences little to no ablation, meaning that the material itself is not eroded during peak heating. Ablative heat shields like the PICA-X system used on SpaceX’s Crew and Cargo Dragons produce distinctly different ‘tails’ during reentry, mainly as a result of the addition of ablated material, much like injecting different elements into a fire or using different materials in rocket nozzles can drastically change the color (and sometimes behavior) of the flame.

While the extreme compressive heating of spacecraft reentering Earth’s atmosphere at many miles/kilometers per second produces plasma instead of what humans recognize as fire, the general idea remains the same. Comparing the reentry tails of spacecraft like the Apollo Command Module, the Space Shuttle, and Orion makes it clear that each vehicle and heat shield produces a subtle but distinctly unique plasma tail over the course of several minutes of peak reentry heating, when the vehicle’s velocity is fast enough to compress atmospheric gases into plasma. Different ablators end up injecting different gases into the superheated plasma tail, hence the different appearance of each tail.

Aside from a unique lack of ablation for Starship’s stainless steel hull and curious hexagonal steel heat shield tiles, SpaceX may end up having to implement a wholly unproven technology known as transpiration cooling, in which some of Starship’s liquid methane propellant would be intentionally pushed out from micro-scale holes drilled or perhaps laser-cut in certain hexagonal plates. After traveling through the steel skin/shield and out of the holes, the liquid methane would almost instantly vaporize into gas and then plasma as it confronts the spacecraft’s superheated bow shock wave, reducing the thermal loads on tiles with such an active cooling solution installed.

It’s unclear what the resulting methane-rich plasma plume might look like but it’s not out of the question that SpaceX’s graphic design team have either done the math themselves, so to speak, or asked engineers to verify what color Starship’s plasma tail might end up looking like. As shown in the latest render, a plume of hues ranging from light blue and indigo to red through white seems entirely plausible. Regardless, Starship is bound to look spectacular during orbital reentries thanks to its metallic skin and shield and planned hot structure, meaning that the entire windward half of the vehicle could end up glowing red, orange, yellow, and even white-hot, precisely like the thermal testing video Musk recently shared.

SpaceX’s first orbital Starship prototype is already under construction at the company’s ad-hoc South Texas ‘shipyard’, for lack of a better term. According to Musk, that vehicle could be ready to be done “around June” of this year, while its complimentary Super Heavy booster could begin assembly as early as April thru June, as well.

TIME honors SpaceX’s Gwynne Shotwell: From employee No. 7 to world’s most valuable company

Time Magazine honors Gwynne Shotwell as SpaceX reaches a $1.25 trillion valuation and eyes its IPO.

Published

By

TIME Magazine has put SpaceX President and COO Gwynne Shotwell on its cover, and the timing could not be more fitting. Published today, the profile of Shotwell arrives at a moment when the company she has quietly run for more than two decades stands at the center of the most consequential developments in aerospace, artificial intelligence, and the future of human civilization.

Shotwell joined SpaceX in 2002 as its seventh employee and has never stopped expanding her role. She oversees day-to-day operations across multiple executive teams spanning Falcon, Starlink, Starship, and now xAI following SpaceX’s February 2026 merger with Elon Musk’s artificial intelligence company, a deal that made SpaceX the world’s most valuable private company at a reported valuation of $1.25 trillion. A highly anticipated IPO is expected in the second quarter of 2026.

Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI

Her track record is historic. She oversaw the first landing of an orbital rocket’s first stage, the first reuse and re-landing of an orbital booster, and the first private crewed launch to Earth orbit in May 2020. She built the Falcon launch manifest from nothing to more than 170 contracted missions representing over $20 billion in business. Under her operational leadership, SpaceX completed 96 successful missions in 2023 alone and has now flown more than 20 crewed Falcon 9 missions. Starlink, which she championed as a financial pillar of the company long before it was a mainstream topic, now connects tens of millions of users worldwide and provided a critical communications lifeline to Ukraine following the 2022 invasion.

Elon Musk has never been shy about what Shotwell means to him and to SpaceX. When she shared her vision for worldwide internet connectivity through Starlink, Musk responded on X with a simple statement, “Gwynne is awesome.” It is a sentiment that has been echoed across the industry. NASA Administrator Bill Nelson once said of Musk: “One of the most important decisions he made, as a matter of fact, is he picked a president named Gwynne Shotwell. She runs SpaceX. She is excellent.”


Now, with Starship targeting its first crewed lunar landing under the Artemis program by 2028, an xAI integration underway, and a pending IPO that could reshape capital markets, Shotwell’s mandate has never been larger. She told Time that 18 Starships are already in various stages of construction at Starbase. “By 2028,” she said, gesturing across the factory floor, “these should be long gone. They better have flown by then.” If Shotwell’s history at SpaceX is any guide, they will.

SpaceX’s IPO might arrive sooner than you think

Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.

Elon Musk’s SpaceX is on the verge of one of the most anticipated Initial Public Offerings (IPO) in history.

However, a new report from The Information indicates the rocket and satellite giant is aiming to file its IPO prospectus with U.S. regulators as soon as this week, or early next week at the latest.

People familiar with the plans told The Information that advisers involved in the process expect the IPO could raise more than 75 billion dollars, potentially making it the largest stock market debut ever and eclipsing Saudi Aramco’s 29.4 billion dollar offering in 2019.

The filing would mark the formal start of what has long been rumored: SpaceX’s transition from a closely held private powerhouse to a publicly traded company.

The timing aligns with earlier signals.

In late February, Bloomberg reported that SpaceX was targeting a confidential IPO filing in March and a possible public listing in June, with a valuation north of 1.75 trillion dollars. At the time, the company’s private valuation hovered around 1.25 trillion dollars.

SpaceX considering confidential IPO filing this March: report

Starlink, SpaceX’s satellite internet constellation, has been the primary driver of that surge, now serving millions of customers worldwide and generating steady revenue. Recent Starship test flights and a record pace of Falcon launches have further bolstered investor confidence.

Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.

A June listing would give SpaceX immediate access to public capital markets at a moment when demand for space-related stocks remains high. It would also allow early employees and long-time investors to cash out portions of their stakes while giving everyday shareholders a chance to own a piece of the company behind reusable rockets, global broadband, and NASA contracts.

Of course, nothing is certain until the SEC filing appears. Market conditions, regulatory reviews, and Musk’s own schedule could still shift timelines.

Yet the latest word from The Information suggests the window has opened. If the filing lands this week, SpaceX’s roadshow could begin in earnest within weeks, setting the stage for what many analysts already call the IPO of the decade.

Elon Musk’s TERAFAB project: Everything you need to know

The CEO has hinted heavily for several quarters that it would probably need to produce its own computing power to stay up to speed on the demand it is facing for its projects. It is now taking matters into its own hands.

On Sunday, Elon Musk formally made TERAFAB official—a groundbreaking $20-25 billion joint venture uniting Tesla, SpaceX, and xAI, three of the world’s richest man’s most significant and powerful ventures.

Musk described the project as “the most epic chip building exercise in history by far.”

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

The initiative aims to produce over one terawatt of AI compute annually, dwarfing the global industry’s current output of roughly 20 gigawatts per year. Musk framed the effort as “the next step towards becoming a galactic civilization,” positioning it as essential for scaling humanity into a multi-planetary species.

The Need for TERAFAB

Existing chip suppliers such as TSMC, Samsung, and Micron cannot expand quickly enough to meet the explosive demand for AI hardware.

Musk explained the situation clearly:

“We’re very grateful to our existing supply chain… but there’s a maximum rate at which they’re comfortable expanding. We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab.”
The CEO has hinted heavily for several quarters that it would probably need to produce its own computing power to stay up to speed on the demand it is facing for its projects. It is now taking matters into its own hands.

Chip Types and Production Goals

The facility will manufacture two specialized chip families, according to the presentation:

  • Edge-inference AI5 and AI6 processors optimized for Tesla’s Optimus humanoid robots and Full Self-Driving systems in vehicles and Robotaxis
  • High-power D3 chips hardened for space environments

Musk outlined annual output targets, which are between 100 and 200 gigawatts of terrestrial compute for robotics, supporting Musk’s vision of producing 1-10 billion Optimus units per year, and the majority (80%) of chips dedicated to orbital AI data centers. Overall, TERAFAB aims to produce 100-200 billion custom AI and memory chips each year.

Scale and Strategy

The size of the TERAFAB project will be remarkable, as Musk indicated after the presentation that the entire Gigafactory Texas campus would not be large enough to fit the needs of the project. In fact, Musk said it would be around 100 million square feet in size, the equivalent of 15 Pentagons or three Central Parks.

Yes, the one in New York City.

Construction will begin with an “advanced technology fab” on the Giga Texas campus in Austin, enabling rapid iteration: design a chip, fabricate lithography masks, produce and test wafers, all within days.

However, the full-scale TERAFAB requires thousands of acres and over 10 gigawatts of power, far exceeding what Giga Texas can accommodate. Musk stated:

“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.”
Multiple large sites are currently under consideration, but this will need a sprawling land mass to get started.

Key Applications

TERAFAB will be a crucial part of the development of some of Tesla’s most valuable projects, including Optimus and data center development, especially from an orbital standpoint. For that reason, we will break this down into Terrestrial and Orbital applications:

  • Terrestrial: Powers autonomous vehicle fleets and billions of Optimus robots performing physical labor
  • Orbital: Starship will launch massive AI satellite constellations, starting with 100-kilowatt “Mini” units, and scaling to larger Megawatt models, creating the world’s largest data center in low-Earth orbit.

Space-based advantages include five times greater solar irradiance, efficient vacuum heat rejection, and freedom from terrestrial grid constraints (U.S. electricity generation totals just 0.5 terawatts). Musk emphasized the principle:

“Quantity has a quality all its own.”

We wrote about SpaceX’s recent filing with the FCC for 1 million orbital data center plans.

Strategic Vision

TERAFAB represents vertical integration at an unprecedented scale, combining AI hardware, robotics, and orbital infrastructure.

Musk described the project as “the final missing piece of the puzzle.” With production ramping toward 2027, TERAFAB is set to accelerate an era of abundance, transforming science fiction into reality and positioning Musk’s companies at the forefront of galactic-scale innovation.
