Although a sister rocket did not fare nearly as well during a separate landing attempt 48 hours later, SpaceX Falcon 9 Block 5 booster B1046 nailed its third successful launch and landing on December 3rd and arrived in Port of Los Angeles a bit less than 48 hours later.

Greeting the rocket after its milestone third reuse was a rare Los Angeles rainstorm, lending a lovely reflective sheen to all uncovered surfaces as low clouds and an obscured sun bathed everything in a stark and uniform off-white light.

It is difficult to conceive of a set of conditions that might serve to better emphasize the well-worn patina of soot and charring now fully covering the once-shiny white exterior of B1046’s fuel and oxidizer tanks, a sort of literal badge of honor for the three orbital-class launches the booster has now supported in the last six months. Functionally speaking, cleaning a Falcon 9 booster from top to bottom would be an unbelievably tedious, time-consuming, and largely pointless task, requiring careful spot-cleaning of something like 400 square meters (4300 square feet).

While SpaceX did repaint recovered Falcon 9 boosters a handful of times around the start of commercial reflights, it always served more of an aesthetic purpose over anything seriously utilitarian. Furthermore, aerospace-grade paint like that used by SpaceX is quite heavy potentially weighing several hundred kilograms per booster and requiring a week at minimum to fully apply a new coat. Some followers like to point out the lost benefits of Falcon 9’s reflective white paint, serving as a mild thermal insulator for Falcon 9’s tanks when filled with supercool propellant. While it certainly exists, the additional heating induced by soot coatings is completely negligible for Falcon 9, which is constantly topped off with chilled propellant prior to launch.

As such, sooty boosters will be around as long as the kerolox-power Falcon family remains in operation. Not too long from now, shiny new Falcon rockets will likely be as rare as the expendable rocket launches they partially represent – the launch vehicles of the future will be rugged workhorses more comparable to the 737s that fill the ranks of airliner fleets than to single-use works of art. Nevertheless, soot is by no means an innate feature of rockets, reusable or otherwise, instead deriving from Falcon 9’s pragmatic choice of kerosene as fuel – soot is simply an inevitable byproduct of kerosene combustion.

 

A long and sooty future

Whenever it begins flying, the sole byproducts of the combustion of BFR/Starlink/Super Heavy’s methane-oxygen (methalox) propellant are water vapor and carbon dioxide, although true methane supplies will inevitably have slight impurities and thus cause the negligible production of some less pleasant byproducts. Raptor, the methalox rocket engine that will power BFR, has been performing hot-fire tests for more than two years, and the sheer differences between the exhaust of Merlin and Raptor are a striking example of the different chemistries at work. As a result of much cleaner combustion, BFR may produce no soot byproducts whatsoever – enjoy it while it lasts!

In the meantime, Falcon 9 will continue to fly and refly for the foreseeable future. B1046’s third successful launch and recovery is a huge step in that direction and the very fact that the most noticeable difference is a new coating of soot at least partially hints at the efficacy of Block 5’s reusability-minded upgrades. Even when twice-flown Block 5 octaweb heat shields are glimpsed, it’s all but impossible to tell the difference between an unflown or twice-flown example, while the new jet-black thermal protection on Block 5 interstages and octawebs only exhibit subtle scarring after reentry heating.

It almost goes without saying that the real killer in multi-use aerospace products – fatigue – is rarely visible to the naked eye, so the external appearance of Falcon boosters is more of a swoon-worthy placebo than anything else. Still, Falcon 9 Block 5 continues to demonstrate that its external appearance is almost equally indicative of truly robust reusability engineering.

SpaceX soars with its first launch as a public company, marking a new era

Published

SpaceX executed its first Falcon 9 launch since going public on June 15, a routine yet symbolically powerful Starlink mission from Vandenberg Space Force Base in California.

Liftoff of the Falcon 9 booster B1093, on its 14th flight, occurred at approximately 8:34 a.m. PDT from Space Launch Complex 4E (SLC-4E), deploying 24 Starlink V2 Mini Optimized satellites into low-Earth orbit.

The first stage successfully landed on the droneship “Of Course I Still Love You” in the Pacific Ocean, underscoring the company’s unmatched reusability track record.

This mission comes just three days after SpaceX’s historic IPO on June 12, which shattered records as the largest ever. The company raised $75 billion by pricing shares at $135, with trading under ticker SPCX on Nasdaq opening at $150 and closing at $160.95—a 19 percent gain—valuing SpaceX at over $2.1 trillion.

The launch highlights the seamless transition from private innovator to public powerhouse. SpaceX, founded in 2002, has revolutionized access to space with over 650 Falcon 9 flights and a massive Starlink constellation now serving millions globally.

As a public company, it faces new pressures: quarterly earnings, shareholder scrutiny, and expectations to accelerate Starship development for Mars ambitions and deeper NASA partnerships. Yet the market response signals strong confidence in its dominance, as launch costs are slashed by 95 percent, rapid satellite deployment, and a backlog of government and commercial contracts.

Ron Baron on Tesla stock

Renowned investor Ron Baron, founder and CEO of Baron Capital, has once again demonstrated his unwavering faith in Elon Musk’s ventures.

Just after SpaceX’s record-breaking IPO, Baron announced he purchased an additional $1 billion in SpaceX (NASDAQ: SPCX) shares. This move pushes Baron Capital’s total holdings in the company to a staggering $25 billion in market value, underscoring one of the most successful private-to-public investment stories in recent history.

Baron’s relationship with SpaceX dates back to 2017, when his firm began investing approximately $1.75–2 billion through secondary markets and employee tender offers at valuations around $20–22 billion.

By the time of the IPO, which valued SpaceX at over $2 trillion with shares closing near $161, those early stakes had generated more than $13 billion in unrealized gains. Post-IPO, Baron’s position ballooned further, reflecting the company’s meteoric rise driven by reusable rocketry, Starlink’s global satellite internet constellation, Starshield defense applications, and ambitious plans for orbital infrastructure.

Baron highlights emerging opportunities like space-based AI data centers and direct-to-cell satellite connectivity, positioning SpaceX at the forefront of a new space economy projected to generate trillions in value.

Critics may question the lofty projections amid high valuations and execution risks, but Baron’s track record speaks volumes. His Tesla holdings, initiated in the mid-2010s, have also delivered outsized returns. As one of the largest institutional holders of SpaceX pre-IPO, Baron Capital’s funds, such as Baron Partners, benefited immensely from valuation markups.

Baron’s $1 billion IPO purchase signals deep confidence in SpaceX’s post-IPO trajectory. In an era of short-term market noise, his strategy exemplifies patient capital: backing visionary leadership and transformative technology.

For investors watching the space sector, it serves as a powerful endorsement that the final frontier may indeed yield the next great wealth-creation engine. As Baron puts it, SpaceX isn’t just building rockets—it’s trying to “save humanity” by expanding our horizons beyond Earth.

SpaceX maintains bold advertising push for Starlink, contrasting Tesla’s minimalistic approach

SpaceX and Tesla, the two flagship companies under Elon Musk’s leadership, share a commitment to groundbreaking technology yet pursue dramatically different paths in how they connect with customers.

Tesla has built its brand through a philosophy of minimal traditional advertising, trusting that exceptional products will generate their own momentum.

SpaceX, by contrast, has embraced high-visibility paid advertising for its Starlink satellite internet service, placing prominent spots during major live sporting events such as the Super Bowl and the recent UFC Freedom 250. This divergence highlights how each company tailors its marketing to the unique demands of its products and target markets.

Tesla’s approach stems directly from Musk’s long-held conviction that superior engineering sells itself. Musk has repeatedly explained that the company redirects resources into research and development rather than endorsements or television commercials.

Tesla’s growth has relied instead on organic channels: enthusiastic owner referrals, viral product reveals like the Cybertruck, extensive media coverage of launches and achievements, and the sheer visibility of its vehicles on roads everywhere.

Even as the company has tested more social media promotions in response to fluctuating demand, its overall strategy remains restrained and digital-focused compared to legacy automakers that pour hundreds of millions into marketing annually.

SpaceX has taken a more assertive route with Starlink to drive widespread consumer awareness. In February of this year, SpaceX aired its first-ever Super Bowl advertisement, marking the initial time any Musk-led enterprise invested in the massive event.

The thirty-second spot emphasized fast and affordable internet available nearly anywhere on the planet, blending inspiring footage of Falcon 9 and Starship landings with narration drawn from science fiction visionary Arthur C. Clarke. United Airlines complemented this with its own Super Bowl commercial showcasing Starlink-enabled high-speed Wi-Fi on flights.

But that is not all SpaceX has done to get word out about its internet service.

Just last night, Starlink branding appeared prominently on the octagon and during the broadcast of UFC Freedom 250, the high-profile event staged on the White House South Lawn. These placements represent a strategic investment in reaching massive, engaged audiences.

The rationale behind SpaceX’s advertising push lies in Starlink’s distinct position as a consumer broadband service. Unlike Tesla’s visually striking cars that act as mobile billboards for early-adopter enthusiasts, Starlink must overcome awareness gaps in rural, remote, and mobile markets where traditional internet infrastructure falls short.

Starlink now serves as SpaceX’s leading revenue generator, with ambitions tied to future growth and potential public offerings. Targeted advertising during sports broadcasts efficiently demonstrates real-world reliability for applications ranging from home connectivity to aviation and live event broadcasting.

Partnerships with airlines and mobile providers further extend its reach, while high-profile placements help convert curiosity into subscriptions amid competition and regulatory considerations.

Ultimately, these contrasting strategies reflect the different maturity levels and competitive landscapes each business navigates. Tesla benefits from built-in visibility and a passionate community that amplifies its message at little cost.

Starlink, operating in the more fragmented broadband sector, requires deliberate efforts to educate and attract mainstream users. By leveraging the spectacle of major sporting events where Tesla once declined to participate, SpaceX is accelerating Starlink toward global ubiquity.

This flexibility underscores a key lesson: even the most innovative companies must adapt their tactics to the practical realities of their markets and customer acquisition challenges.
