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.

California city weighs banning Elon Musk companies like Tesla and SpaceX

A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”

A California City Council is planning to weigh whether it would adopt a resolution that would place a ban on its engagement with Elon Musk companies, like Tesla and SpaceX.

The City of Davis, California, will have its City Council weigh a new proposal that would adopt a resolution “to divest from companies owned and/or controlled by Elon Musk.”

This would include a divestment proposal to encourage CalPERS, the California Public Employees Retirement System, to divest from stock in any Musk company.

A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”

It claims 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.”

If adopted, Davis would bar the city from entering into any new contracts or purchasing agreements with any company owned or controlled by Elon Musk. It also says it will not consider utilizing Tesla Robotaxis.

A staff report on the proposal claims there is “no immediate budgetary impact.” However, a move like this would only impact its residents, especially with Tesla, as the Supercharger Network is open to all electric vehicle manufacturers. It is also extremely reliable and widespread.

Regarding the divestment request to CalPERS, it would not be surprising to see the firm make the move. Although it voted against Musk’s compensation package last year, the firm has no issue continuing to make money off of Tesla’s performance on Wall Street.

The decision to avoid Musk companies will be considered this evening at the City Council meeting.

The report comes from Davis Vanguard.

It is no secret that Musk’s political involvement, especially during the most recent Presidential Election, ruffled some feathers. Other cities considered similar options, like the City of Baltimore, which “decided to go in another direction” after awarding Tesla a $5 million contract for a fleet of EVs for city employees.

Starlink restrictions are hitting Russian battlefield comms: report

The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.

SpaceX’s decision to disable unauthorized Starlink terminals in Ukraine is now being felt on the battlefield, with Ukrainian commanders reporting that Russian troops have struggled to maintain assault operations without access to the satellite network. 

The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.

Lt. Denis Yaroslavsky, who commands a special reconnaissance unit, stated that Russian assault activity noticeably declined for several days after the shutdown. “For three to four days after the shutdown, they really reduced the assault operations,” Yaroslavsky said.

Russian units had allegedly obtained Starlink terminals through black market channels and mounted them on drones and weapons systems, despite service terms prohibiting offensive military use. Once those terminals were blocked, commanders on the Ukrainian side reported improved battlefield ratios, as noted in a New York Post report.

A Ukrainian unit commander stated that casualty imbalances widened after the cutoff. “On any given day, depending on your scale of analysis, my sector was already achieving 20:1 (casuality rate) before the shutdown, and we are an elite unit. Regular units have no problem going 5:1 or 8:1. With Starlink down, 13:1 (casualty rate) for a regular unit is easy,” the unit commander said.

The restrictions come as Russia faces heavy challenges across multiple fronts. A late January report from the Center for Strategic and International Studies estimated that more than 1.2 million Russian troops have been killed, wounded, or gone missing since February 2022.

The Washington-based Institute for the Study of War also noted that activity from Russia’s Rubikon drone unit declined after Feb. 1, suggesting communications constraints from Starlink’s restrictions may be limiting operations. “I’m sure the Russians have (alternative options), but it takes time to maximize their implementation and this (would take) at least four to six months,” Yaroslavsky noted.

SpaceX and its AI subsidiary xAI are reportedly competing in a new Pentagon prize challenge focused on autonomous drone swarming technology, as per a report from Bloomberg News

The six-month competition was launched in January and is said to carry a $100 million award.

Bloomberg reported that SpaceX and xAI are among a select group invited to participate in the Defense Department’s effort to develop advanced drone swarming capabilities. The goal is reportedly to create systems that can translate voice commands into digital instructions and manage fleets of autonomous drones.

Neither SpaceX, xAI, nor the Pentagon’s Defense Innovation Unit has commented on the report, and Reuters said it could not independently verify the details.

The development follows SpaceX’s recent acquisition of xAI, which pushed the valuation of the combined companies to an impressive $1.25 trillion. The reported competition comes as SpaceX prepares for a potential initial public offering later this year.

The Pentagon has been moving to speed up drone deployment and expand domestic manufacturing capacity, while also seeking tools to counter unauthorized drone activity around airports and major public events. Large-scale gatherings scheduled this year, including the FIFA World Cup and America250 celebrations, have heightened focus on aerial security.

The reported challenge aligns with broader Defense Department investments in artificial intelligence. Last year, OpenAI, Google, Anthropic, and xAI secured Pentagon contracts worth up to $200 million each to advance AI capabilities across defense applications.

Elon Musk previously joined AI and robotics researchers in signing a 2015 open letter calling for a ban on offensive autonomous weapons. In recent years, however, Musk has spoken on X about the strengths of drone technologies in combat situations.
