On May 27th, the European Space Agency (ESA) published updated renders of a proposed spacecraft, called the Earth Return Orbiter (ERO). ERO would be the last of four critical elements of a joint NASA-ESA Mars sample return mission, meant to return perhaps 1-5 kg (2-11 lb) of Martian samples to scientists on Earth. In a best-case scenario, such a sample return is unlikely to happen before the tail-end of the 2020s and will probably slip well into the 2030s, barring any unexpected windfalls of funding or political support.

Enter SpaceX, a private American company developing Starship/Super Heavy – a massive, next-generation launch vehicle – with the goal of landing dozens of tons of cargo and just as many humans on Mars as few as 5-10 years from now. The radically different approaches of SpaceX and NASA/ESA are bound to produce equally different results, while both are expected to cost no less than $5B-$10B to be fully realized. What gives?

The high price of guaranteed success

  • As proposed, the Mars sample return mission will be an extraordinary technical challenge.
    • At a minimum, the current approach involves sending a single-stage-to-orbit (SSTO) rocket from Earth to Mars, landing the SSTO with extreme accuracy on the back of a new Mars lander, deploying a small rover to gather the sample container, loading that container onto the tiny rocket, launching said rocket into Mars orbit, grabbing the sample with large orbiter launched from Earth, and returning said sample to Earth where it will reenter the atmosphere and be safely recovered.
  • This downright Rube Golberg machine-esque architecture is nevertheless the best currently available with current mindsets and hardware. It’s also likely the only way NASA or ESA will independently acquire samples of Mars within the next few decades, barring radical changes to both the mindsets and technologies familiar and available to the deeply bureaucratic spaceflight agencies.
  • However, this is by no means an attempt to downplay the demonstrated expertise and capabilities of the space agencies and their go-to contractors. Both ESA and NASA have a decades-long heritage of spectacular achievements in robotic space exploration, reaching – however briefly, in some cases – almost every major planet and moon in the solar system.
    • The NASA-supported Jet Propulsion Laboratory (JPL) remains a world-leading expert of both designing, building, and landing large, capable, and long-lived rovers/landers on the surface of Mars. JPL also has a track record of incredible success with space-based orbiters, including Cassini (Saturn), Magellan (Venus), Galileo (Jupiter), Voyager (most planets, now in interstellar space), Stardust (comet sample return), Mars Reconnaissance Orbiter (MRO, Mars orbiter) and more.
  • This success, however, can often come with extreme costs. NASA’s next Mars rover – essentially a modified copy of the Curiosity rover currently operating on Mars and a critical component of the proposed sample return – is likely to cost more than $2B, while Curiosity cost ~$2.5B. The Cassini Saturn orbiter cost around ~$3.5B for 15 years of scientific productivity. ESA’s Rosetta/Philae comet rendezvous cost at least $2B total. In the scheme of things, it would be hard to think of a more inspiring way to spend that money, but the fact remains that these missions are extremely expensive.

High risk, high reward

  • The price of missions like those above may, in fact, be close to their practical minimum, at least relative to the expectations of those footing the bill. However, it’s highly likely that similar results could be achieved on far tighter budgets, another way to say that far more returns could potentially be derived from the same investment.
    • The easiest way to explain this lies in the fact that the governments sponsoring and funding ESA and NASA have grown almost dysfunctionally risk-averse, to the extent that failure really isn’t an option in the modern era. Stakeholders – often elected representatives – expect success and often demand a guaranteed return on their support before choosing to fight for a given program’s funding.
    • As it turns out, an unwillingness to accept more than a minute amount of risk is not particularly compatible with affordably attempting to do things that are technically challenging and have often never been done before. That happens to be a great summary of spaceflight.
    • As risk aversion and the need for guaranteed success grew hand-in-hand, a sort of paradox formed. As politicians strove to ensure that space agency funding was efficiently used, space agencies became far more conservative (minimizing results and the potential for leaps forward) and the cost of complex, capable spacecraft grew dramatically.
    • The end result: spacecraft that are consistently reliable, high-performance, derivative, and terrifyingly expensive.
  • SpaceX is in many ways an anathema of the low-risk, medium-reward, high-cost approach that government space agencies and their dependent contractors have gravitated towards over the last 40-50 years. Instead, SpaceX accepts medium to high risk to attain great rewards at a cost that space agencies like NASA and ESA are often unable to accept as possible after decades of conservatism.
    • This is the main reason that it’s possible that NASA/ESA and SpaceX will both succeed in accomplishing goals at a dramatically disproportionate scale with roughly the same amount of funding.
    • If NASA/ESA bite the bullet and begin to seriously fund their triple-launch Mars Sample Return program, the missions will take a decade or longer and cost something like $5 million per gram of soil returned to Earth, but success will be all but guaranteed.
    • Both SpaceX’s Starship/Super Heavy and Mars colonization development programs run significant risks of hitting major obstacles, suffering catastrophic failures, and could even result in the death of crew members aboard the first attempted missions to Mars.
    • For that accepted risk, the rewards could be unfathomable and the costs revolutionary. SpaceX could very well beat the combined might of ESA and NASA to return large samples of Martian soil, rock, and water to Earth, all while launching ~100,000 kg into Martian orbit instead of the sample return’s ~10 kg.
    • In a best-case scenario, SpaceX could land the first uncrewed Starship on Mars as early as 2022 or 2024. Barring some unforeseen catastrophe or the company’s outright collapse, that first uncrewed Mars landing might happen as late as the early 2030s, around the same time as NASA and ESA’s ~10kg of Mars samples will likely be reentering Earth’s atmosphere.
  • Regardless of which approach succeeds first, space exploration fans and space scientists will have a spectacular amount of activity to be excited about over the next 10-20 years.

Tesla has lost the director who designed one of the company’s best features: Over-the-Air updates.

Thomas Dmytryk, who has spent over 11 years with Tesla and helped to develop Over-the-Air updates and the company’s vehicles’ ability to utilize them to improve, has decided to leave. In a lengthy statement on LinkedIn, Dmytryk said that he’s “closing the book.” He had nothing but good things to say:

“After 11 incredible years at Tesla, I’m closing the book. It’s been the ride of a lifetime: always on the news, innovating relentlessly, constantly pushing the limits. Tesla is THE place for talented, passionate people. I feel insanely lucky to have been part in that culture for so long.”

It appears the intense lifestyle of developing and creating intensively for so long might have caught up to Dmytryk, who did not give his definitive plans for the future, and it appears he may be taking some time off before jumping into a new venture:

“The future? Extremely bright. Ambitions intact, just getting started as a transformative company that could elevate billions of lives. So why leave now?! Human life’s always been my North Star, right now I need to be with mines. I’ve always admired Tesla’s top leadership and vision. But what I’ve always found incredible is the tenacity, brilliance and devotion of people on the front line. YOU make Tesla unstoppable. I wish you all the best and of course EPIC wins.”

The move was first reported by NotaTeslaApp.

Over-the-Air updates are among Tesla’s best features. They are used to improve the Full Self-Driving suite, add features, remedy recalls, and more. Many vehicles have the ability to receive OTA updates, as I did in a Ford Bronco previous to my Model Y. However, Tesla does them better than anyone else: they’re seamless, effective, and frequent. Your car always improves.

The move is a blow to Tesla, of course, considering Dmytryk’s massive contribution to the company and extremely long tenure spent, but not something that is overwhelmingly detrimental. Tesla deals with a lot of extremely intelligent people, some of whom are the best in their field, so they are sure to find a suitable replacement.

However, it’s no secret that the company has been losing some of its top talent, some of whom were in executive roles. Some have left to take on new projects, and others have not revealed their career plans.

It seems at least some of those employees are simply deciding to walk away and try new things after working so hard for so long. According to Dmytryk’s LinkedIn, he also played a large part in Musk’s acquisition of X, as he stated he “worked at Twitter/X ~45/week while working at the same pace for Tesla.”

That averages a 13-hour day, seven days a week, or 18 hours for the normal five-day work week.

Tesla’s most wanted Model Y heads to new region with no sign of U.S. entry

Unlike the standard Model Y, the “L” stretches the wheelbase by roughly 150 mm and the overall length by about 177 mm to 4,976 mm. The result is a genuine 2-2-2 seating layout that gives six adults proper legroom and cargo space — a true family hauler without the cramped third-row compromises of many three-row SUVs.

Tesla’s most wanted Model Y configuration is heading to a new region, and although U.S. fans and owners have requested the vehicle since its release last year, it appears the company has no plans to bring it to the market.

According to fresh regulatory filings, the six-seat Model Y L is coming to South Korea with signs indicating an imminent launch. The extended-wheelbase configuration, already a hit in China, just cleared energy-efficiency certification from the Korea Energy Agency, paving the way for deliveries as early as the first half of 2026.

The vehicle is already built at Tesla’s Giga Shanghai facility in China, making it an ideal candidate for the Asian market, as well as the European one, as the factory has been known as a bit of an export hub in the past.

It seems like Tesla was prepping for this release anyway, as the timing was no accident. A camouflaged Model Y L prototype was spotted testing on Korean highways the same day the certification dropped. Tesla has already secured similar approvals for Australia and New Zealand, with both markets expecting the larger Model Y in 2026.

Unlike the standard Model Y, the “L” stretches the wheelbase by roughly 150 mm and the overall length by about 177 mm to 4,976 mm. The result is a genuine 2-2-2 seating layout that gives six adults proper legroom and cargo space — a true family hauler without the cramped third-row compromises of many three-row SUVs.

South Korean filings list it as an all-wheel-drive imported electric passenger vehicle with a 97.25 kWh total battery capacity supplied by LG Energy Solution. Local tests show an impressive 543 km (337 miles) combined range at room temperature and 454 km (282 miles) in colder conditions, easing one of the biggest concerns for Korean EV buyers.

Tesla Model Y lineup expansion signals an uncomfortable reality for consumers

But for U.S. fans, things are not looking good for a launch in the market.

CEO Elon Musk has been blunt. The six-seater “wouldn’t arrive in the U.S. until late 2026, if ever,” he said, pointing to the company’s heavy bet on unsupervised Full Self-Driving and robotaxi platforms like the Cybercab. With the Model X slated for discontinuation, many families hoped the stretched Model Y would slide into the lineup as an affordable three-row bridge. So far, that hope remains unfulfilled.

For now, South Korean drivers will be among the first buyers outside China to enjoy the spacious, efficient Model Y L. Tesla continues its global rollout strategy, tailoring vehicles to regional tastes while North American customers keep refreshing their apps and crossing their fingers.

The Model Y L proves the appetite for practical, family-sized electric SUVs is stronger than ever. Hopefully, Tesla will listen to its fans and bring the vehicle to the U.S. where it would likely sell well.

Tesla is ramping up its advertising strategy on social media

Tesla has long stood out in the automotive world for its unconventional approach to advertising—or, more accurately, its near-total avoidance of it. For over a decade, the company spent virtually nothing on traditional marketing.

Tesla seems to be ramping up its advertising strategy on social media once again. Marketing and advertising have not been a major focus of Tesla’s, something that has brought some criticism to the company from its fans.

However, the company looks to be making adjustments to that narrative, as it has at times in the past, as ads were spotted on several different platforms over the past few days.

On Facebook and YouTube, ads were spotted that were evidently placed by Tesla. On Facebook, Tesla was advertising Full Self-Driving, and on YouTube, an ad for its Energy Division was spotted:

Tesla has long stood out in the automotive world for its unconventional approach to advertising—or, more accurately, its near-total avoidance of it. For over a decade, the company spent virtually nothing on traditional marketing.

In 2022, Tesla’s U.S. ad spend was roughly $152,000, a rounding error compared to General Motors’ $3.6 billion the following year.

Traditional automakers averaged about $495 per vehicle on ads; Tesla spent $0. CEOElon Musk’s stance was explicit: “Tesla does not advertise or pay for endorsements,” he posted on X in 2019. “Instead, we use that money to make the product great.”

The strategy relied on word-of-mouth from delighted owners, Elon’s massive X following, viral product launches, media frenzy, and customer referrals. A great product, Musk argued, sells itself. It does not need Super Bowl spots or billboards. Resources poured into R&D instead, with Tesla investing nearly $3,000 per car, far more than rivals.

Tesla counters jab at lack of advertising with perfect response

This reluctance wasn’t arrogance; it was philosophy, and Musk made it clear that the money was better spent on the product. Heavy spending on ads was seen as wasteful when innovation and authenticity drove organic demand. Shareholder calls for marketing budgets were ignored.

The current shift, paid Facebook ads promoting Full Self-Driving (Supervised) and YouTube Shorts offering up to $1,000 back on Powerwall batteries, marks a pragmatic evolution.

These targeted campaigns coincide with the end of one-time FSD purchases and a March 31 deadline for FSD transfer eligibility on new vehicles.

This move likely signals Tesla adapting to scale, as well as a more concerted effort to stop misinformation regarding its platform. As EV competition intensifies and the company bets big on robotaxis and energy storage, pure organic buzz may not suffice to hit adoption targets. Selective digital ads allow precise, cost-effective reach without abandoning core principles.

If successful, it could foreshadow measured expansion into marketing, boosting high-margin software and home energy revenue while preserving Tesla’s innovative edge. But, it’s nice to see the strategy return, especially as Tesla has been reluctant to change its mind in the past.
